$(document).ready 之外的脚本

发布于 2024-11-09 05:18:29 字数 445 浏览 3 评论 0原文

我为客户构建了一个网站,当用户单击导航链接时,链接页面的内容会动态加载并使用 JQuery 进行转换,而不是加载新页面。

我遇到的问题是,因为它没有加载新页面,所以 $(document).ready 不会再次触发,并且各个页面上的任何 JS 都会被破坏。例如,如果您访问 http://www.woodlandexotica.com/species.php 页面工作正常,但如果您尝试从 http://www.woodlandexotica.com/index_dev.php,JS将无法工作。

我不是 JS 专家,我真的很感谢所有的帮助!

I have built a site for a client and when the user clicks on a navigation link, the content of the linked page is dynamically loaded and transitioned in with JQuery, instead of loading the new page.

The problem I am having is that because it is not loading a new page, $(document).ready doesn't fire again and any JS on the individual pages gets broken. For example, if you visit http://www.woodlandexotica.com/species.php the page works correctly, but if you try to navigate to the page from http://www.woodlandexotica.com/index_dev.php, the JS won't work.

I'm not an expert in JS and I really appreciate any and all help!

问题是,当您调用“.load()”时,您正在使用 URL 字符串和选择器后缀来从加载的内容中提取内容。当您以这种方式使用“.load()”时,jQuery 会删除所有脚本并且不会运行它们。除了实现您自己的“.load(”版本之外,您无能为力。 )”您自己,或者(更好)让您加载的其他页面不是是完整的 HTML 页面。如果您在 URL 字符串上使用不带选择器后缀的“.load()”,则 jQuery 运行脚本。

有关详细信息,请参阅 jQuery 错误 6307。该错误不会被修复,但希望文档能够得到改进。

The problem is that when you call ".load()", you're using a URL string and a selector suffix to extract from the loaded content. When you use ".load()" that way, jQuery strips out all the scripts and does not run them. There's nothing you can do about that other than to implement your own version of ".load()" yourself, or (better) have the other pages you load not be complete HTML pages. If you use ".load()" without the selector suffix on the URL string, then jQuery does run the scripts.

See jQuery bug 6307 for more. The bug will not be fixed but hopefully the documentation will be improved.

您组织这段代码的方式是错误的,

只保留 document.ready 内部的绑定,并将逻辑移到外部的函数中。任何页面都可以访问该函数。

$(document).ready(function() {

            currentImg = 1;

        var currentContainer = activeContainer;

        } else {

The way you organized this code is wrong

Keep only binding's inside document.ready and move the logic outside to a functions..which can be accessed by any page.

$(document).ready(function() {

        var currentContainer = activeContainer;
        if(activeContainer == 1) {
            activeContainer = 2;
        } else {
            activeContainer = 1;
