ajax & php & javascript

Ivan P

Hello!

I have a index.php that on one click calls via AJAX a file.php.

index.php looks like this:

<html >
<head>

<script language="javas cript" type="text/javascript" >
var http; // We create the HTTP Object
var dest;
var prenosi;
function getHTTPObject() {
var xmlhttp;
/*@cc_on
@if (@_jscript_vers ion >= 5)
try {
xmlhttp = new ActiveXObject(" Msxml2.XMLHTTP" );
} catch (e) {
try {
xmlhttp = new ActiveXObject(" Microsoft.XMLHT TP");
} catch (E) {
xmlhttp = false;
}
}
@else
xmlhttp = false;
@end @*/
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
try {
xmlhttp = new XMLHttpRequest( );
} catch (e) {
xmlhttp = false;
}
}
return xmlhttp;
}

function processStateCha nge(){
if (http.readyStat e == 4){
contentDiv = document.getEle mentById(dest);
if ((http.status == 200)||(http.sta tus==0)){
response = http.responseTe xt;
contentDiv.inne rHTML = response;
} else {
contentDiv.inne rHTML = "Error: Status "+http.stat us;
}
}
}

function loadHTML(URL, destination){
dest = destination;
var url;
http = getHTTPObject() ;
if(http){
http.onreadysta techange = processStateCha nge;
http.open("GET" , URL, true);
http.send(null) ;
}
}

</head>
<body>

<span onclick="loadHT ML(file.php','' )">Click</span><br>
</html>

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - - - - - - - -

file.php looks like this:

<span id="countdownco ntainer">
write something down
<script type="text/javascript">
document.write( "1")
</script>
</span>

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - - - - - - - -

The problem is that "write something down" displays on the Internet
Explorer, but number 1 doesn't. If we call just file.php - it works then -
it displays both. Why is javascript not executing from ajax called
procedure?

It won't in most other browsers as well.

Yes.
Why is javascript not executing from ajax called procedure?

It has nothing to do with it being an "ajax called procedure". It has to
do with inserting the script via innerHTML and the script blocks don't
get processed when doing that.

If you want to execute script blocks, then you will have to use a
different method of inserting it in the page to get the browser - any
browser - to execute the script.

The only browser I recall that executed script's inserted via innerHTML
was NS6.

What are other methods than innerHTML that support processing JavaScripts on
callback? ... so I can search a web for examples...

AJAX & PHP - generate report & force download?

by: k.mitz | last post by:

Hi, I have a PHP application that allows users to generate a .pdf report of their database content. Normally, I've had to refresh a page to call the script to generate the report, so there's a second or so when the browser goes blank. I was wondering if it was possible to use AJAX to call the script to generate the report, then begin the download without refreshing the page (or in the case of I.E., leaving me with a blank window that...

Ajax & Large Listbox

by: Jeremy | last post by:

I've got a very large listbox that gets populated using ajax. The listbox and a button are in a panel inside an update panel. The button click of the button sets the panel visible property to false. Everything works nice and snappy except for when I click the button. The panel takes about 20 or so seconds to dissapear. I think the ajax call has been made and the browser is executing some javascript synchronously because the browser is...
