What is Javascript Stacktrace?
A Javascript tool that allows you to debug your Javascript by giving you a stack trace of function calls leading to an error (or any condition you specify)
How do I use Javascript Stacktrace?
Just include stacktrace.js file on your page, and call it like so:
<script type="text/javascript" src="path/to/stacktrace.js" />
<script type="text/javascript">
... your code ...
if (errorCondition) {
var trace = printStackTrace();
//Output however you want!
alert(trace.join('\n\n'));
}
... more code of yours ...
</script>
New! bookmarklet available on the project home page.
You can also pass in your own Error to get a stacktrace:
<script type="text/javascript">
var lastError;
try {
// error producing code
} catch(e) {
lastError = e;
// do something else with error
}
// Returns stacktrace from lastError!
printStackTrace({e: lastError});
</script>
Some people recommend just assigning it to window.onerror:
window.onerror = function() {
alert(printStackTrace().join('\n\n'));
}
What browsers does Javascript Stacktrace support?
It is currently tested and working on:
- Firefox (and Iceweasel) 0.9+
- Google Chrome 1+
- Safari 3.0+
- IE 5.5+
- Konqueror 3.5+
- Flock 1.0+
- SeaMonkey 1.0+
- K-Meleon 1.5.3+
- Epiphany 2.28.0+
- Iceape 1.1+
Working (readable, valid stack trace) but not perfectly tested on:
- Opera 7+
