Okay, so I have an javascript function that retrieves some HTML…

function updateQuestions(i){
    var url = 'getQuestions.php?sys=' + i;
    if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
        receiveReq.open("GET", url, true);
        receiveReq.onreadystatechange = handleQuestionsUpdate; 
        receiveReq.send(null);
    }
}

function handleQuestionsUpdate() {
    if (receiveReq.readyState == 4) {
        var a=receiveReq.responseText;
        document.getElementById('questions').innerHTML=a;
        checkSpeakers(); //Error Occurs Here, even though checkSpeakers() is a function in the returned HTML chunk.
    }   
}

This HTML is not just HTML, but it is more specifically a form and a chunk of javascript. The javascript is hard-coded into the HTML and not referenced by <script src=”..”>

Is it normal that this retrieved JS code isn’t recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update?

This is the text being returned to the javascript function.

function checkPillowSpeakers()
{
    var pillowSpeakers = document.getElementById('Q9').value + document.getElementById('Q10').value;
    document.getElementById('PS1').style.display = ((pillowSpeakers > 0)? '' : 'none');
    document.getElementById('PS2').style.display = ((pillowSpeakers > 0)? '' : 'none');
}~ARRAYSEPERATOR~<html>....</html>

The JS Code is seperated from the HTML code by an ~ARRAYSEPERATOR~ tag. The issue is that I don’t want to EXECUTE the code at this time, I just want it queued so I can call it on command.

    After doing a whole lot of research, it seems Eval() has some memory issues… so I actually came across this solution:

    //Firstly, create a div called codeHolder

var javascriptCode="function test(){.....}";
var JSONCode=document.createElement("script");
JSONCode.setAttribute("type","text/javascript");
JSONCode.text=javascriptCode;

var cell=document.getElementById("codeHolder");
if ( cell.hasChildNodes() )
    while ( cell.childNodes.length >= 1 )
        cell.removeChild( cell.firstChild );

cell.appendChild(JSONCode);
