    Need some regex help with basic syntax highlighter.

    in JavaScript

    Posted · Edited by SoItBegins

    Thanks for tip. I finally got it working (almost) but it seems to be a little too greedy item.innerHTML = item.innerHTML .replace(new RegExp('"([^"]|("))*"', 'g'), "<span class="string">$&</span>"); It highlights it like that: a = "I am string for test if escaping "can 'break' it.."; b = 'I am string for test if escaping 'can "break" it..';So I found this:{x}Repeat the previous character, set or group exactly x times.

     

    but "([^"]|("))*"{1} doesn't tell it to stop at first match

    I tried "([^"]|("))*?" but still no effect. Could you tell me what else is wrong with it. Just wondering how much slower/faster it would work If I'd build highlighter manually by using indexOf() to find first quote and and then while loop to find next quote that is not escaped.

    Thanks.I still don't get what I am doing wrong. :(

    item.innerHTML =  item.innerHTML .replace(new RegExp('"([^"]|(")*)?"', 'g'), "<span class="string">$&</span>");
    the code above is based on this example
    // Mimic leading, negative lookbehind like replace(/(?<!es)t/g, 'x')var output = 'testt'.replace(/(es)?t/g, function($0, $1){	return $1 ? $0 : 'x';});
    Edit: Could you tell me if this part of regex is correct: ([^"]|(")*)?

    Trying to upload file with JS.

    Thanks a lot. I got it work that way.

     

    I have one extra question: whats the best way for removing iframe with deleted file from files list?

     

    I have structure like:

    iframe1

    iframe2

    ...

    iframenSeparate iframe for every file.

     

    And what I am currently doing is that once upload is complete I echo delete link back to user:

    echo "File: ". basename( $_FILES['uploaded']['name']). ' <a href="./upload.php?a=delete&file='.$id.'">delete</a>';

    And when user clicks on that link I inform him about it:

     die("File have been successfully deleted.");

    But in my opinion it would look nicer if that iframe were removed instead of displaying "File have been successfully deleted." there. What's the best way of doing that? Can I make that delete link inside iframe so that it would also delete iframe itself or should I write javascript code that would check iframe contents once in every second and delete it if it contains "File have been successfully deleted."?Just looking forward to hear some thoughts/ideas on that.

    Hello.Could anyone give me info about file uploading?

     

    Here's my html form

    <form enctype="multipart/form-data" action="upload.php" method="POST">Please choose a file: <input name="uploaded" type="file" /><br /><input type="submit" value="Upload" /></form>

    And when I hit submit button I get the following post parameter

    -----------------------------31112091625756rnContent-Disposition: form-data; name="uploaded"; filename="acp.css"rnContent-Type: text/cssrnrn body {rn        font: 13px arial, helvetica, sans-serif;rn    }rnrntd.this {rn        font: 13px arial, helvetica, sans-serif;rn    }rnrn    #header ul {rn        list-style: none;rn        padding: 0;rn        margin: 0;rn    }rnrn    #header li {rn        float: left;rn        border: 1px solid #307C99;rn        border-bottom-width: 0;rn        margin: 0 1 0 0;rn    }rnrn    li.Selected {rn        position: relative;rn        top: 1px;rn        background-color: #dbedff;rn    }rnrn    li.NotSelected {rn        position: relative;rn        top: 1px;rn        background-color: #99ccff;rn    }rnrn    #content {rn        border: 1px solid #307C99;rn        clear: both;rn		background-color: #dbedff;rn    }rnrnTABLE,TR,TD,BODY,SELECT,INPUT,BUTTON,TEXTAREA{font-size :12px }rnrna{rn	text-decoration: none;rn	color: #0011ff;rn}rnrnrn-----------------------------31112091625756--rn

    I would like to know what's this called? 31112091625756. I guess I need to know what it is in order to generate valid post parameter.

    Here is javascript submitter I've made so far. Could anyone tell if there is better/easier way that does not include jQuery ? Like formObject.submit() without reloading whole page and with out having to manually write post parameter or something?

    function getXMLObject()  //XML OBJECT{   var xmlHttp = false;   try {     xmlHttp = new ActiveXObject("Msxml2.XMLHTTP")  // For Old Microsoft Browsers   }   catch (e) {     try {       xmlHttp = new ActiveXObject("Microsoft.XMLHTTP")  // For Microsoft IE 6.0+     }     catch (e2) {       xmlHttp = false   // No Browser accepts the XMLHTTP Object then false     }   }   if (!xmlHttp && typeof XMLHttpRequest != 'undefined') {     xmlHttp = new XMLHttpRequest();        //For Mozilla, Opera Browsers   }   return xmlHttp;  // Mandatory Statement returning the ajax object created}var xmlhttp = new getXMLObject();    //xmlhttp holds the ajax objectfunction Upload(action) {  var getdate = new Date();  //Used to prevent caching during ajax call  if(xmlhttp) {    xmlhttp.open("POST","./index.php?p="+p+"&a=upload&id="+id,true); //ToServer    xmlhttp.onreadystatechange = handleServerResponse;    xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');	var post_data = "Editor=" + txtname.value+"&title="+escape(txttitle.value);    xmlhttp.send(post_data); //Posting txtname to PHP File  }}

    Hello.

     

    I am trying to write very basic syntax highlighter. It has to be able to highlight strings quoted in different ways and keywords.

     

    Here is my javascript code:

    	var codes = document.getElementsByClassName('code');	for (var i = 0; i < codes.length; ++i) {		var item = codes[i];		alert(decodeHTMLEntities(item.innerHTML));		item.innerHTML =  item.innerHTML .replace(new RegExp('"([^"]*)"', 'g'), "<span class="string">$&</span>");		//item.innerHTML =  item.innerHTML .replace(new RegExp(keywords, 'g'), "<span class="keyword">$&</span>");	}

    Here is how it currently highlights:

     

    a = "I am string for test if escaping "can break it..";And this is how it should be highlighted

     

    a = "I am string for test if escaping "can break it..";I would also like to know how I could avoid highlighting keywords in string.I know there are enough ready to use highlighters available, but my intention is to get better at javascript/regex by writing at least basic one myself/with help of this forum.Would anyone be so nice and tell me how I could write regex that would do what I want it to?

     

    Why does my page look ugly in IE but okey in rest of browsers?

    in HTML/XHTML

    Posted · Edited by SoItBegins

    Thanks for pointing out that. Forgot to add BuildTable() here. Previous post edited in order to have example for those who have same problem. BuildTable() It just returns html.

     

     

    The reason your code sample doesn't reach the second alert is because alert() is blocking the other elements from loading in the other browsers. Javascript is singlethreaded. Alert() stops javascript in its tracks. It just may be that FF is loading a little more than the other browsers the microseconds before firing the alert() function. Try console.log() and compare the difference.

    Wrong. Yes it is singlethreaded but wonce you click ok the code execution continues.

     

    The innerHTML property is read-only on the col, colGroup, frameSet, html, head, style, table, tBody, tFoot, tHead, title, and tr objects.

    Ok so here is minimal code that demonstrates the problem. Run it with IE first and then with any other browser. What you can see is that in IE you will see empty page, in other browsers you would see "hello"

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head>	<meta content="text/html; charset=UTF-8" http-equiv="content-type">	<title>Title</title></head><body><table id="BOARDSETTINGS"></table><script language="javascript" type="text/javascript">hGeneral= document.getElementById("BOARDSETTINGS");hGeneral.innerHTML = "<tr><td>hello</td></tr>";</script></body></html>

    And here is quick fix for IE

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head>	<meta content="text/html; charset=UTF-8" http-equiv="content-type">	<title>Title</title></head><body><table id="BOARDSETTINGS"></table><script language="javascript" type="text/javascript">function setTBodyInnerHTML(tbody, html) {  var temp = tbody.ownerDocument.createElement('div');  temp.innerHTML = '<table>' + html + '</table>';  tbody.parentNode.replaceChild(temp.firstChild.firstChild, tbody);}hGeneral= document.getElementById("BOARDSETTINGS");setTBodyInnerHTML(hGeneral,"<tr><td>hello</td></tr>")</script></body></html>

    Which shows that IE really is the worst nightmare of web developer.

    I did not have any unclosed <b> tag there but what I found was that as soon as I changed.

     body {        font: 13px arial;    }

    to

     body {        font: 13px;    }

    The bold text problem was gone.Edit: found solution:

    TABLE,TR,TD,BODY,SELECT,INPUT,BUTTON,TEXTAREA{font:11px Tahoma;color:#000}

    A little googling revealed that arial is known to be overweight with IE.Edit2:I figured the cause of my form problem too:

    hGeneral= document.getElementById("BOARDSETTINGS");alert("1");hGeneral.innerHTML = "<tr><td>hello</td></tr>";alert("2");

    Code execution actually never reaches to alert("2"); however it does in FF.IE says:

    SCRIPT600: Invalid target element for this operation.acp.php?id=12&a=MANAGE_SETTINGS, line 176 character 1

     

    however I have <table id="BOARDSETTINGS"></table> above javacript. Any ideas what might cause that?

    Dont you see it like this:ievsff2.pngOr this difference between IE and FF (which can be only see when you look it directly from server and which somehow gets fixed as you save page to disk).

    I am trying to get it up somewhere more accessible place than my home computer as soon as possible, but until that all I can show you is these 2 pictures.

    Thanks again Ingolme. I also figured that <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> didnt work for IE but <!DOCTYPE html> worked. Could <!DOCTYPE html> cause any problems for older browsers that doesnt support html 5?

    If you could show a link to the working page I'd be able to find the problem quickly.

     

    I am currently hosting it in localhost because it's easier to edit files thatway. I guess the saved page should do the same. Actually the code I posted here is already minimal code.

     

    I will upload it somewhere when I get chance to.

     

    However if you are lucky you might be able to get in http://62.65.214.232/a/lib/acp.php?id=12&a=MANAGE_SETTINGS

    with user: test and password: test .Here's acp.zip zip file demonstrates that with IE "Allow BBCode" and "If set to yes, bbcode will be parsed" are both bold but with firefox only "Allow BBCode" is bold (as it should be)Other problem with page attached and linked page is that with IE you will only see submit button. with firefox you will also see form itself. However when you save page and then open that saved file (from zip) then IE also shows form, but it doesn't show it when you view it directly from server.

    Hello.I am facing some problems with html. At the top I have firefox (and it also looks so in other browsers) and the bottom one is IE.Problem is that with IE font is bold and title bar is too tall. (almost no white space between tabs and this blue title bar.) Could anyone tell me how I could fix this please?ievsff.png

    Here is my test.css

     body {        font: 13px arial, helvetica, sans-serif;    }td.this {        font: 13px arial, helvetica, sans-serif;    }    #header ul {        list-style: none;        padding: 0;        margin: 0;    }    #header li {        float: left;        border: 1px solid #307C99;        border-bottom-width: 0;        margin: 0 1 0 0;    }    li.Selected {        position: relative;        top: 1px;        background-color: #dbedff;    }    li.NotSelected {        position: relative;        top: 1px;        background-color: #99ccff;    }    #content {        border: 1px solid #307C99;        clear: both;		background-color: #dbedff;    }TABLE,TR,TD,BODY,SELECT,INPUT,BUTTON,TEXTAREA{font-size :12px }a{	text-decoration: none;	color: #0011ff;}

    And here is my html 

    <html><head>  <meta http-equiv="content-type" content="text/html; charset=UTF-8">  <link rel="stylesheet" type="text/css" href="./test.css"></head><body><div style="text-align: left; width: 100%; background-color: #99ccff"><div style="float:right; text-align: left;"><span>Some text</span></div><h1>Title</h1></div><div id="header"><ul id="TabTop"><li class="Selected"><a href="?id=1">TAB1</a></li><li class="NotSelected"><a href="?id=3">TAB2</a></li><li class="NotSelected"><a href="?id=10">TAB3</a></li><li class="NotSelected"><a href="?id=12">TAB4</a></li></ul></div><div id="content">	<table style="text-align: left; width: 100%;" border="0" cellpadding="2" cellspacing="2">	  <tbody>		<tr>		  <td style="vertical-align: top; width: 200px;">		    <a href="#">Link1<br></a>			<a href="#">Link2<br></a>			<a href="#">Link3<br></a>		  </td>		  <td style="vertical-align: top;">Sample text<br>		  </td>		</tr>	  </tbody>	</table></div><br></body></html>

    Thanks in advance.

    Need help with eval

    in PHP

    Posted

    I am trying to eval if condition but for somereason ""itworks" never gets printed. When you call my_if(true||false); directly, it'll return true but not when you eval code.Does anyone know how to eval expression of trues and falses to get only 1 true or false?

    <?phpfunction my_if($cond){    return $cond;}if(eval("my_if(true||false);")){    print("itworks\n");}?>

    Examples (let T be true and F be false):T||T shall give TT||F shall give TT&&(T||F) shall give T since (T||F) is T therefore T &&T is T
