Or j("#button").trigger("mousedown"); which will execute the code in the onmousedown attribute and any event handlers attached to the "mousedown" event.

You can use:

eval(script);

The eval() function evaluates and/or executes a string of JavaScript code.

First, eval() determines if the argument is a valid string, then eval() parses the string looking for JavaScript code. If it finds any JavaScript code, it will be executed.

You can use the js eval function.

document.write("<br />" + eval("2+2"));

the eval will execute the string script..
