Javascript函数在Chrome中不起作用

Question

For some reason javascript functions are not working right now.

function alert(){
alert('Close')
}

When I trigger the alert using:

<span onclick="alert()">Hi</span>

I get the following error:

Uncaught RangeError: Maximum call stack size exceeded

What could be wrong? Is it something wrong with jQuery?

Example (of the error): http://jsfiddle.net/qNjjN/show

Answer 1

You've overridden the default alert() function with your own! So when you call alert() within the method it is making an infinite recursive call.

Rename your method to something else and it will be fine :)

Answer 2

The issue here is that there is a native javascript function called alert and you are essentially overriding it with your alert function.

When you call your function, your function calls itself over and over. This is called recursion and in your case results in your error.

Answer 3

You have an infinite loop by calling alert from itself. This would be fine as a recursive function but there's currently no logic to end itself.
