使用链式 Jquery 插件

问题描述

我正在尝试在 CakePhp (http://www.appelsiini.net/项目/链式)我使用 Jquery 来测试警报并且可以正常工作，但只是链接插件不起作用.我正在尝试使用他们的代码来遵循他们网站上的示例.如果您想查看我的页面，请转到 http://team.southpacificavionics.com/customers/test登录:访客密码:密码

I am trying to use the remote Chained plugin in CakePhp (http://www.appelsiini.net/projects/chained)I used Jquery to test an alert and that works but just the chained plugin is not working. I am trying to follow the example on their website using their code. If you want to view my page go to http://team.southpacificavionics.com/customers/testlogin: guestpassword: password

推荐答案

这实际上与 CakePHP 无关——它是一个客户端 javascript 库.

This has nothing to do with CakePHP really - it's a client-side javascript library.

但是你有两个问题，第一:

But you have two problems, first:

(function() {
    $("#series").chainedTo("#mark");
});

实际上并没有运行"，您只是定义了一个匿名函数，如果被调用，将运行.它应该只是移动到您 alert 所在的位置:

Is not actually "running", you just defined an anonymous function that would run, if called. It should just be moved, probably, to where you're alert resides:

<script type="text/javascript">
    $(document).ready(function () {
        $("#series").chainedTo("#mark");
    });
</script>

现在它会运行，但如果你检查浏览器控制台，它会出错，类似于:

Now it'll run, but if you checked the browser Console, it'll be erroring out, something like:

未捕获的类型错误:$(...).chainedTo 不是函数

库似乎运行不正确.

我不确定您从哪里获得 jquery 链式库的源代码，但它不是您链接的 github 页面中的当前版本:

I'm not sure where you got the source code for the jquery chained library, but it's not the current version in the page you link's github grab it from:

https://github.com/tuupola/jquery_chained/

此处列出了直接最小化版本:
