    in my color chart, I have set 3 addEventListeners for this chart. [*][*]click on any color(it will transform the viewing scale i,e; zoom the color element for better view)[*]an event for selecting the color by double clicking on it(it will show the color hex code inside a div)[*]an mouseout event (which will retrun the scale size to its normal size) Everything works fine. The problem is after 3 to 4 time experiment with the color chart small elements behind the zoomed element is visible and if mouse coursor touches them mouseout event triggers which is not desirable.mozila ,opera, chrome both behaving the same.opera and chrome not even zoom the element properlywhat's the reason and how can it be fixed? <html><head><style>#colorchart{ position:fixed;

    i am trying to learn how to make a text editor.here i creat a paragraph using "para" button.and inside the paragraph there will be a quote.Every time I press 'enter' within this paragraph, a new paragraph is created, rather than a line break tag (<br>). How can I force a line break tag to be created instead of a paragraph element?also i cant even get outside of the quote tag.though designMode is on and contenteditable is true for both paragrap and quote <head><meta charset="utf-8"><title>Untitled Document</title><style>*{margin:0px;padding:0px;}#idContent{ background-color:pink;}div{ border:1px solid black;}</style></head><body onLoad="loads();" style="position:relative;"><iframe id="idContent" width="600" height="280" contenteditable="true" ></iframe><input type="button" value="para" onClick="para();"><script>function loads(){ idContent.document.designMode="On";}function para(){ var m=document.createElement("p"); m.setAttribute('style',"border:1px solid black;height:100px;width:500px;position:relative;background-color:white;");m.setAttribute('designMode',"on");m.setAttribute('contenteditable',"true"); var t=document.createElement("q"); t.innerHTML="quote here"; t.setAttribute('designMode',"on"); t.setAttribute('contenteditable',"true"); m.appendChild(t); idContent.document.body.appendChild(m); }</script></body></html>

    thanks!spell correction works but it is not allowing me to click on the link and visit the desired page.rather "open in a new tab" using mouse's right button works.i want to make it a clickable link. iframe tag is used to creat browser window inside the main page(as far as i know).so why should i need an iframe tag here? // what i am trying to do is select a word or group of word and replae it with a link

    if(!var_name)

    alzami replied to alzami's topic in JavaScript

    thanks!what actually cofused me is i removed the timer_is_on var from the editor and codes worked fine.so i wonder why use an extra var when it is not necessary!!

Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).</p></div><input type="button" value="select and change" onClick="addLink();"><script>function addLink(){var links=prompt("add link","http://");document.execCommand('creatLink',false,links);}</script></body></html>

    browser detecting problem .before that codes works fine.its job is to make a div up and down within a period of time.after 10/12 times it crashes?what is the reason and how can it be fixed? <!doctype html><html><head><meta charset="utf-8"><title>Untitled Document</title><style>#its{ width:200px; height:0px; background-color:blue; display:block; color:white;}#h{ background-color:green;}</style></head><body><div id="its">this is it</div><input type="button" value="down" onClick="view();" id="h"><script>var i=100;function view(){ var m=document.getElementById("its"); var n=document.getElementById("h"); m.style.webkitTransition="height .5s ease-in-out"; m.style.height="100px"; n.value="up" setTimeout(function(){ m.style.height="0px"; n.value="down"; },600); setInterval(view,1200); } </script></body></html>

    if(!var_name)

    alzami replied to alzami's topic in JavaScript

    in this example what is the use of the variable (timer_is_on)? http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_win_settimeout_cleartimeout2 it is not even needed here. what is the use of If(!timer_is_on) in the function startcount()??

    i am trying a dynamic max power and "x" value input.everything is fine the problem is i can not replace the (x^something) dynamically with replace() method. <!doctype html><html><head><meta charset="utf-8"><title>Untitled Document</title><style>#gap{ width:200px; height:50px; border:1px solid black;}thiss{ width:200px; height:50px;}</style></head><body><div id="gap"></div><p id="thiss"></p><input type="button" value="replace this" onClick="change();"><script>function change(){ var m=document.getElementById("gap"); var n=document.getElementById("thiss"); var t=document.getElementById("thiss").innerHTML; var power=prompt("input highest power of x:"); var i; var arr=new Array(); for( i=power;i>=0;i--){ arr[i]=prompt("coeff of x^"+i); } i=power; for(i=power;i>=0;i--){ if(arr[i]>0 && i==power){ n.innerHTML += arr[i]+"*x^"+i; } else if(arr[i]<0 && i==power){ n.innerHTML += arr[i]+"*x^"+i; } else if(arr[i]>0 && i!=power){ n.innerHTML += "+"+arr[i]+"*x^"+i; } else if(arr[i]<0){ n.innerHTML += arr[i]+"*x^"+i; }else if(arr[i]==0){ n.innerHTML += ""; } } var x_val=prompt("solve with x =");i=power;for(i=power;i>=0;i--){ m.innerHTML=eval(t.replace(/x^i/,"Math.pow(x_val,i)"));} }</script></body></html> mainly problem is here.i know this is garbage .but how can it be fixed.how can i replace using variable for(i=power;i>=0;i--){ m.innerHTML=eval(t.replace(/x^i/,"Math.pow(x_val,i)"));}

    string.replace

    alzami replied to alzami's topic in JavaScript

    what did you just do here? n.replace(/x3/g,""+Math.pow(3,3)) i mean the rule behind it(actually i am not following any books.so little explanation will be a great help)

    string.replace

    alzami replied to alzami's topic in JavaScript

    i am not suggesting anything.i wanted to use a ^ sign to make the statement more understandable.and i am using the string.replace function for the first time.it worked if i just use x2 instead of x^2. i used a backslash to seperate ^ as suggested.it shows the replaced string in the text field .not evaluating. of course there is a mistake.i am failing to figure it out. this simple code works fine <!doctype html><html><head><meta charset="utf-8"><title>Untitled Document</title><style>#gap{ width:200px; height:50px; border:1px solid black;}</style></head><body><div id="gap"></div><p id="thiss">3*x3</p><input type="button" value="replace this" onClick="change();"><script>function change(){ var m=document.getElementById("gap"); var n=document.getElementById("thiss").innerHTML; var rep1=n.replace(/x3/g,"3"); m.innerHTML=rep1 var t=eval(m.innerHTML); m.innerHTML=t;}</script></body></html> if i pass Math.pow(3,3) in stead of 3 eval function don't evaluate it.It pulish 3*Math.pow(3,3)in the screen. but this script works fine....but what could be the mistakes in previous code? <script>function change(){ var m=document.getElementById("gap"); var n=document.getElementById("thiss").innerHTML; var rep1=eval(n.replace(/x3/g,"Math.pow(3,3)")); m.innerHTML=rep1;}</script>

    if you see my codes in post 1 you will find that i used eval function there to evaluate.not worked
