jQuery resize function doesn't work on page load
提问by Nicki
How do I get this function to not only run on window resize but also on initial page load?
如何让这个函数不仅在窗口调整大小时运行，而且在初始页面加载时运行？
$(window).resize(function() {
...
});

You'll want to use:
你会想要使用：
$(document).ready(function() { /* your code */ });
To make something happen onload. If you want something to work onload and onresize, you should do:
使某些事情发生在加载。如果你想要一些东西在 onload 和 onresize 上工作，你应该这样做：
onResize = function() { /* your code */ }
$(document).ready(onResize);
$(window).bind('resize', onResize);

I think the best solution is just to bind it to the load and resize event:
我认为最好的解决方案是将其绑定到 load 和 resize 事件：
$(window).on('load resize', function () {
// your code
});

This behavior is by design.
此行为是设计使然。
You should put your code into a named function, then call the function.
您应该将代码放入一个命名函数中，然后调用该函数。
For example:
例如：
function onResize() { ... }
$(onResize);
$(window).resize(onresize);
Alternatively, you can make a plugin to automatically bind and execute a handler:
或者，您可以制作一个插件来自动绑定和执行处理程序：
$.fn.bindAndExec = function(eventNames, handler) {
this.bind(eventNames, handler).each(handler);
};
$(window).bindAndExec('resize', function() { ... });
Note that it won't work correctly if the handler uses the eventobject, and that it doesn't cover every overload of the bindmethod.
请注意，如果处理程序使用该event对象，它将无法正常工作，并且它不会涵盖该bind方法的每个重载。

$(document).ready(onResize);
$(window).bind('resize', onResize);
didn't work with me.
没有和我一起工作。
Try
尝试
$(window).load('resize', onResize);
$(window).bind('resize', onResize);
instead.
反而。

Another approach, you can simply setup a handler, and spoof a resize event yourself:
另一种方法，您可以简单地设置一个处理程序，并自己欺骗调整大小事件：
// Bind resize event handler through some form or fashion
$(window).resize(function(){
alert('Resized!');
});
// Trigger/spoof a 'resize' event manually
$(window).trigger('resize');
