changing javascript variable value

Recommended Posts

spidermanbz

Hello you all! Would somebody help me with a doubt concerning javascript variables? DaleHohm posted the following:

#include <IE.au3>

$oIE = _IECreate()

_IEDocWriteHTML($oIE, "<html><head><script language = 'javascript'>foo='bar';</script></head><body></body></html>")

ConsoleWrite("foo = " & $oIE.document.parentwindow.eval('foo') & @CR)

This was in response to a user that wanted to check a javascript variable value. What if I wanted to change that value after a remote webpage has loaded? For instance, if I navigate to a site which has the code below, how can I alter the value of "x" so that I can manipulate the clock after the page is already running?

<html>
<head>
<script>
var x = 31;
var y = 1;
function startClock() {
    if (x !== 'Done') {
        x = x-y;
        document.frm.clock.value = x;
        setTimeout("startClock()", 1000);
    }
    if (x == 0) {
        x = 'Done';
        document.frm.clock.value = x;
        success.location.href="success.php";
    }
}
</script>
</head>

<body onload="startClock()">
<form name="frm">
<input name="clock" size="3" readonly="readonly" style="font-size: 25pt; font-family: Verdana;" type="text">
</form>
</body>
</html>

BTW, where can I find documentation on these stuff? I mean properties and methods like $oIE.document.parentwindow.eval ?

Thank you very much!

Unless I miss my initial guess - it is illegal to do this. Why do you want to do this, and what is the URL of the site.

You miss.

$oIE.document.parentwindow.eval('x=7;')

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

This looks tough - gorilla tough.
