JQUERY:将div调整到窗口宽度

I am trying to force the width of a div to the width of a browser window. So that even if the window is resize the adjusts it's width.

我试图将div的宽度强制为浏览器窗口的宽度。所以即使窗口调整了大小它的宽度。

I have been researching for about an hour and have found odd bits and pieces such as .resize() but can't find anything which works.

我已经研究了大约一个小时，发现了一些奇怪的东西，比如.resize()，但是找不到任何有用的东西。

Without a container limiting the width, a div should span the width of the browser window by default. You can explicitly set the width to 100%, but that shouldn't be necessary:

如果没有限制宽度的容器，div应该在默认情况下跨越浏览器窗口的宽度。您可以显式地将宽度设置为100%，但这是不必要的:

<div style="width:100%;">Hello world</div>

I think CSS is more appropriate here, but you can do this in jQuery like this:

我认为CSS在这里更合适，但是你可以用jQuery这样做:

$("#div1").width($(window).width());

To run the above code whenever the window is resized, you can do this:

要在窗口调整大小时运行上述代码，您可以这样做:

$(window).resize(function(){
    $("#div1").width($(window).width());
});

Here's a jsFiddle. For the sake of demonstration, the div expands on button click.

<div id="full"></div>

<script type="text/javascript">
    function reSize($target){
        $target.css('width', $(window).width()+'px');
    }
    $(document).ready(function(){
        $(window).bind('resize', reSize($('#full')));
        $(window).trigger('resize');
    });
</script>
