AJAX is Javascript.If you can't show the rest of the code or link to your page it won't be easy to help you.

ow sorry, the website is ******and u can login with username: test1pass: test1the page must reload when u are login.at the moment im ive delete the reload pease of the code because i cant call a function automatically when u got any more questions please ask them

[Ingolme]

Well, you don't seem to be calling the checkAll() function at any moment. It won't run if you don't call it.

<span class="tekstheader">Welkom test1! Je bent succesvol ingelogd!</span><br>Je wordt automatisch door gestuurd.<script type="text/javascript"> checkAll(); alert("sdf");</script> is the script when im login, u can see after the text i call the function (checkAll), the alertbox also doesn't work, way i dont have any idee way?

If you're trying to pull in Javascript code using AJAX, you're going to need to use eval to run it. When you add an AJAX response to a page it doesn't get executed, it's just text. If you want to execute any code you will need to isolate the Javascript portion of the code and use eval. eval will give an error if you try to use it on any non-Javascript code, including HTML.

thnx for the tip, i will go check it outi think u mean http://www.w3schools.com/jsref/jsref_eval.asp this functionsfor a test i have try<script type="text/javascript"> eval("alert('Hello world')");</script> but i still dont get any pop-up or error from the javascript. i have also put it into the index.php (just for testen) and then i get a pop-up. so i think im doing wrong but what?

[Synook]

But... can you show us the AJAX bit of your code?

[traxion]

surehttp://cammora.be/functions/func_javascript.js is mine function, i use the function verstuur() for the ajaxthis is a way how i call it <a onclick="verstuur('algemeen-signup.php')">i don't now if u need more info, but its javascript so u should also have the possible to check it out with the site. if u need more info u can always ask for it

[traxion]

oke.. i think not everybody understands mine problem. i will try to explain it a time again.im making a site (cammora) with ajax. i've create mine own ajax function (http://cammora.be/functions/func_javascript.js) and a way to call it is<a onclick="verstuur('algemeen-signup.php')"> now im having a problem using javascript in the ajax, i've been told that ajax disable javascript as protection. U can there is a function called eval() where u can force the javascript to be executed.so i've tried to use the function http://www.w3schools.com/jsref/jsref_eval.asp , but to bad it all isn't working for me.does anybody can tell me way it isn't working or better tell me the solution?

<div id="main">		<table border="0" width="600">	text and the content of the page</table><script type="text/javascript">eval("x=10;y=20;document.write(x*y)");document.write("<br />");document.write(eval("2+2"));document.write("<br />");var x=10;document.write(eval(x+17));document.write("<br />");</script><script src="http://www.google-analytics.com/urchin.js" type="text/javascript"></script><script type="text/javascript">_uacct = "UA-3036431-2";urchinTracker();</script>										</div>

already thnx for the replays

[Ingolme]

Well, before I start searching for more errors, there's already this case:You're calling the function with one parameter:verstuur('algemeen-signup.php')and the function needs four:function verstuur(page, type, name, value)

[traxion]

thats correct. but when u don't need to parameters u can leave them empty, just like in PHP. I didn't get any errors, in IE or FF so i thought it was oke here is a complete function call where all the parameters are filledverstuur('misdaad-route66.php', 'post', new Array('submit1', 'bestuurder', 'kogels'), new Array('dummy', getElementById('bestuurder').value, getElementById('kogels').value))

You didn't understand what I was saying. This is the function you have to handle the ready state changing:

function StatusGewijzigd() { 	if (xmlHttp.readyState==4) document.getElementById("content-main").innerHTML=xmlHttp.responseText;}

All you do is take the response content and write it to the page. That doesn't work with Javascript. You need to eval the code instead. This would work to execute java script:

function StatusGewijzigd() { 	if (xmlHttp.readyState==4) eval(xmlHttp.responseText);}

But pay attention to what I'm about to say. That only works if the response text is Javascript code. So if this is the response text:alert('test');Then the above code will work. If the response text has anything other then Javascript code, eval will fail. This will fail:<script type="text/javascript">alert('eval');</script>That fails because of the script tags. Script tags are not Javascript code, they are part of HTML. The eval function does not evaluate HTML code. Likewise, eval will fail if it sees any other HTML tags.So, if your response text is HTML only then you can use the innerHTML property to put it on the page. If the response text is Javascript only then you can use eval to execute the code. If the response is both HTML and Javascript, then you will need to build a very complex piece of code to find the Javascript embedded inside the HTML and execute it independently of anything you do with the HTML.

oke.. thnx for the clear explanationi don't have right now the time to test it so i've going to ask itis it possible to first the html part and then the eval/ javascript part so that on the page in the end both are loaded?i think of not but just asking for sureeverybody thnx for the replays:)

[justsomeguy]

Of course it's possible, if you want to write all the code that does that. It would be easier to send one request for the HTML, which you write to the page, and a second request for the Javascript, which you eval.

[traxion]

oke... thnx for the infoi've got time to test it all in the weekend, i will update this post with mine experience

[traxion]

thnx man. its works easyive put a function into the eval and then i can do with the javascript what i want:D
