jQuery可排序列表不会序列化，为什么? [英] Jquery sortable list won't serialize, why?

问题描述

我正在Zend Framework应用程序中使用jquery实现可排序的图像列表. 我只是无法使用.sortable('serialize')方法返回比空字符串更多的内容.

I'm implementing a sortable list of images with jquery in a Zend Framework application. I just can't get the .sortable('serialize') method to return more than an empty string.

当我在应用程序之外尝试一些简单的示例时，它会起作用.

When I try with a few simple examples outside my application it works.

下面的代码片段是否被其他各种标签包裹起来很重要.我认为不应该.应该通过ID来找到无序列表，对吧?

Does it matter that the snippet below is wrapped in various other and other tags. I think it shouldn't. The unordered list should be found just by the id, right?

HTML:

<ul id="mylist">
    <li id="1">
        <div>
            <img src="image_1.jpg" />
            <p class="value_item">some text</p>
        </div>
    </li>
    <li id="2">
        <div>
            <img src="image_2.jpg" />
            <p class="value_item">some text</p>
        </div>
    </li>
</ul>

JavaScript:

JavaScript:

$(document).ready(function() {                 
    $('#mylist').sortable({ 
        update: function() {
            var order = $('#mylist').sortable('serialize');
            alert(order);
        }                         
    });
});

如果序列化返回空字符串，请确保id属性包含下划线.它们必须采用以下格式:"set_number"例如，具有ID属性 foo_1，foo_5，foo_2 的3元素列表将序列化为foo [] = 1& foo [] = 5& foo [] = 2.您可以使用下划线，等号或连字符来分隔字符集和数字.例如foo = 1或foo-1或foo_1都序列化为foo [] = 1.

If serialize returns an empty string, make sure the id attributes include an underscore. They must be in the form: "set_number" For example, a 3 element list with id attributes foo_1, foo_5, foo_2 will serialize to foo[]=1&foo[]=5&foo[]=2. You can use an underscore, equal sign or hyphen to separate the set and number. For example foo=1 or foo-1 or foo_1 all serialize to foo[]=1.
