Question

I’m trying to troubleshoot a problem with someone else’s JavaScript file, and they declared a function like the following.

function window.confirm(str) {
..... code here .....
}

This works fine with IE, but in Google Chrome, it throws an uncaught syntax error on the period in window.confirm. I tried to put a try catch around it like below, but that didn’t work, same syntax error. It then won’t let me use any functions defined in that JavaScript file.

try {
    var window.confirm = function(str) {
        ..... code here .....
    };
}
catch(e) {}

I also tried to change the declaration to a variable, like below, but that didn’t work either. Same error.

var window.confirm = function(str) {
    ..... code here .....
};

Is there a way to catch this in Chrome?

Answer 1

function window.confirm(str) and var window.confirm ... are invalid. instead, try:

window.confirm = function(str){
..... code here .....
}
