加载动态“选择"选择元素

问题描述

我正在使用选择的 jQuery 插件(由 Harvest 提供).它在 (document).ready 上运行良好，但我有一个按钮，单击该按钮时，它使用 ajax 动态创建更多我想使用选择"功能的选择对象.但是，只有原始的选择元素具有选择"功能，而新的(动态创建的)不起作用.我正在使用 jQuery.get 附加新元素.以下是代码示例:

I am using the jQuery plugin chosen (by Harvest). It is working fine on (document).ready, but I have a button that, when clicked, uses ajax to dynamically create more select objects that I want to use the "chosen" feature. However, only the original select elements have the "chosen" features, and the new (dynamically created) do not work. I am using jQuery.get to append the new elements. Here is a sample of the code:

jQuery(".select").chosen();//this one loads correctly
jQuery("#add-stage").click(function() {
    jQuery.get('/myurl',{},function(response) {
            //response contains html with 2 more select elements with 'select' class
            jQuery('#stages').append(response);
        jQuery(".select").chosen();//this one doesn't seem to do anything :-(
    });
});

我在想我在某个地方需要一个 .live() 函数，但我还没有弄清楚.非常感谢任何帮助！

I was thinking that I need a .live() function somewhere, but I haven't been able to figure that out yet. Any help is much appreciated!

注意 - 我没有尝试动态加载新选项，如使用文档中指定的那样 trigger("liszt:updated");

推荐答案

确保 response 元素具有 select 类.

Ensure that the response elements have the select class.

console.log( response );  // to verify

仅将插件应用于新元素也是一个好主意.

May also be a good idea to only apply the plugin to the new element(s).

jQuery(".select").chosen();

jQuery("#add-stage").click(function() {
    jQuery.get('/myurl',{},function(response) {
        console.log( response ); // verify the response

        var $response = $(response);  // create the elements

        $response.filter('.select').chosen(); // apply to top level elems
        $response.find('.select').chosen();   // apply to nested elems
        $response.appendTo('#stages');
    });
});

另外，如果 /myurl 返回整个 HTML 文档，您可能会得到不可预知的结果.

Also, if /myurl is returning an entire HTML document, you may get unpredictable results.
