Javascript jQuery脚本运行于（文档）.ready和$（窗口）.resize
我对javascript/jQuery一无所知 我有一个用jQuery（document）调用的脚本。准备好了，这很好，我还希望在调整窗口大小时脚本能够自我更新。脚本的调用方式如下：Javascript jQuery脚本运行于（文档）.ready和$（窗口）.resize,javascript,jquery,resize,ready,Javascript,Jquery,Resize,Ready,我对javascript/jQuery一无所知 我有一个用jQuery（document）调用的脚本。准备好了，这很好，我还希望在调整窗口大小时脚本能够自我更新。脚本的调用方式如下： jQuery(document).ready(function($) { $('#accordion').AccordionImageMenu({ 'openPc': <?PHP echo $params['openPc']; ?>, 'width':<?PHP
jQuery(document).ready(function($) {
$('#accordion').AccordionImageMenu({
'openPc': <?PHP echo $params['openPc']; ?>,
'width':<?PHP echo $params['width']; ?>,
'height':<?PHP echo $params['height']; ?>,
'effect': '<?PHP echo $params['effect']; ?>',
'duration': <?PHP echo $params['duration']; ?>,
'openItem': <?PHP echo ($params['keepMenuItemOpen'] ==1)? $openItem : "null"; ?>,
'border' : <?PHP echo $params['border']; ?>,
'color' : '<?PHP echo $params['color']; ?>',
'position' : '<?PHP echo $params['position']; ?>',
'fadeInTitle': <?PHP echo $params['fadeInTitle']; ?>
});
});
我想出来了。而不是添加$（窗口）.resize（函数（）{在调用页面中，我将其添加到包含的JS文件中。通过这种方式，我可以“看到”触发器并对其进行操作。为了对其进行操作，我创建了一个名为resize的新函数，该函数更新了我所需的参数。缺点：如果用鼠标手动调整浏览器窗口的大小，它会将菜单的大小一次调整1个像素，这并不完美，而且不会改变有时会摔倒。如果你只是简单地从一种尺寸换到另一种尺寸，那么效果就很好。这是完成的代码。我相信有更好的方法（提示），但我已经用尽了我自己的知识

参数的宽度和高度在页面发送到客户端之前由php设置。一旦客户端接收到页面，所有动态代码都由javascript处理。感谢您的回复，所讨论的参数不是我需要动态更改的参数，下面是我设法修改以响应的脚本片段[code]var menuWidth=$（'#accordion'）.width（）；//根据menuWidth var openDim=Math.round（menuWidth*（_this.menuSettings.openPc/100））；[/code]我只需要脚本重新计算[code]var menuWidth=$（'#accordion'）.width（）；[/code]从问题中不清楚你想做什么。调整手风琴的大小？如何调整？注释中的代码很难阅读。什么是
