jQuery get max width of child div's

Question

I need to get the max width(just the one width) of the child div in the wrapper div element ```

```

Accepted Answer

```
Math.max.apply(Math, $('.image').map(function(){ return $(this).width(); }).get());
```

Per suggestion, I'll break that down:

```
$('.image').map(function(){
   return $(this).width();
}).get();
```

The above gets a list of all `.image` divs and converts it into a list of their widths. So you'll now have something like: `[200, 300, 250, 100, 400]`. The `.get()`, as Felix pointed out, is necessary to get an actual Array instead of a jQuery array.

`Math.max` takes N arguments, so you have to call it as: `Math.max(200, 300, 250, 100, 400)`, which is what the `Math.max.apply` piece accomplishes.
