Javascript array of strings

Question

so I encountered weird problem here. I have an array `status=new Array()`. Then I iterate from `0` to `N-1`, and assign `status[i]="idle";` I tried to do alert to check the values, and they are all assigned to a character coma `,`. Anyone knows what's wrong? ``` var status=new Array(); window.onload = function() { for(var i=0;i<5;i++) { status[i]="idle"; alert(status[i]); } } ```

Accepted Answer

Use a different variable name (or better yet, don't use global variables at all). There's a `window.status` property already, and apparently something isn't letting you shadow it with your own (which surprises me slightly; I wonder if the array is being coerced to a string on assignment or something). At global scope, `var` creates properties on the `window` object, which is why `window.status` is relevant.

This example (source) replicates your problem (for me, using Chrome), and this example (source) with just a changed name shows the correct series of alerts.

Note that this is browser-specific. On Firefox, even your old code shows me the correct series of alerts. E.g., Firefox is allowing us to redefine `window.status`, but Chrome isn't.
