Maximum call stack size exceeded error

I am using a Direct Web Remoting (DWR) JavaScript library file and am getting an error only in Safari (desktop and iPad)

It says

Maximum call stack size exceeded.

What exactly does this error mean and does it stop processing completely?

Also any fix for Safari browser (Actually on the iPad Safari , it says

JS:execution exceeded timeout

which I am assuming is the same call stack issue)

It means that somewhere in your code, you are calling a function which in turn calls another function and so forth, until you hit the call stack limit.

This is almost always because of a recursive function with a base case that isn't being met.

Viewing the stack

Consider this code...

(function a() {
    a();
})();

Here is the stack after a handful of calls...

As you can see, the call stack grows until it hits a limit: the browser hardcoded stack size or memory exhaustion.

In order to fix it, ensure that your recursive function has a base case which is able to be met...

(function a(x) {
    // The following condition 
    // is the base case.
    if ( ! x) {
        return;
    }
    a(--x);
})(10);

如果你不小心导入/嵌入了相同的JS文件两次，你有时可以得到这个，值得在检查员的资源标签中检查:)

In my case, I was sending input elements instead of their values:

$.post( '',{ registerName: $('#registerName') } )

Instead of:

$.post( '',{ registerName: $('#registerName').val() } )

This froze my Chrome tab to a point it did even show me the 'Wait/Kill' dialog for when the page becomes unresponsive...
