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.

Answer 1

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);
