setTimeout Internet Explorer

Question

I have the following javascript in MSIE:

setTimeout(myFunction, 1000, param );

this seems to work in all browsers except internet explorer. the param just doesnt get forwarded to the function. looking at the debugger, it is undefined.

Just use an anonymous function... – Farid Nouri Neshat Mar 05 '12 at 14:40 — Farid Nouri Neshat, Mar 05 '12 at 14:40

param in Internet explorer specifies whether the code in myFunction is JScript, JavaScript or VBscript ^{See also: MSDN}. It does not behave like other browsers.

The following will work:

setTimeout(function() {
    myFunction(param);
}, 1000);

The previous line does not exactly mimic setTimeout in Firefox etc. To pass a variable, unaffected by a later update to the param variable, use:

setTimeout( (function(param) {
    return function() {
        myFunction(param);
    };
})(param) , 1000);

@clamp The `param` at the bottom is the original `param` variable. `param` at the top is a local variable for the self-invoking function. `param` at the middle resolves to `param` at the top. – Rob W Mar 05 '12 at 16:59
thank you! everything seems to work now in all browsers, just some post processing tools like jshint and google closure compiler complain that this is invalid syntax. but i guess, this should be another question then. – clamp Mar 05 '12 at 17:02
I don't get any warnings/errors with the snippet alone in the [Closure Compiler](http://closure-compiler.appspot.com/home) or [JSHint](http://www.jshint.com/). – Rob W Mar 05 '12 at 18:01
i have to mention that the parameter is an array like this: [a,b] – clamp Mar 06 '12 at 09:09
@clamp That's still not sufficient. If you really want to solve this (interesting?) problem, don't hesitate to post a new question, including the relevant code to demonstrate your case. – Rob W Mar 06 '12 at 15:21

Internet Explorer does not allow you to pass parameters like that. You'll have to do it explicitly from the callback function:

setTimeout(function(){
    myFunction(param);
}, 1000);

Quote from MDN:

Note that passing additional parameters to the function in the first syntax does not work in Internet Explorer.

Take a look at http://www.makemineatriple.com/2007/10/passing-parameters-to-a-function-called-with-settimeout

Looks like you'll need something like this:

setTimeout(function(){ myFunction(param) }, 1000);

That isn't a parameter. Apparently, that last argument is denoting the scripting language.

Use an anonymous function instead:

setTimeout(function() {
  myFunction(param);
}, 1000);

Use an anonymous function:

setTimeout(function() { myFunction(param) }, 1000);

How about this:

setTimeout(function(){
    myFunction(param);
}, 1000);

you can use closure:

setTimeout(function(){myFunction(param)}, 1000);
