我为这个推出了我自己的选择器,并为它制作了一个插件。这是我第一次制作jQuery插件,所以欢迎任何建议或反馈。代码高度依赖于jquery1.4.2、jqueryui的CSS格式的弹出窗口和
DataTables
用于表格格式化和分页的插件。
jquery.tablepicker.js
(function($) {
// Shell for the plugin code
$.fn.tablePicker = function(options) {
// Plugin code
var tbl = null;
return this.each(function() {
// for each item in selector
options = $.extend($.fn.tablePicker.defaults, options);
tbl= $('#'+options.tblName);
$(tbl).wrap(options.container);
if(!$.isEmptyObject(options.header)){
var headerHtml= '<div align="center">' + options.header + '</div>';
$(this).find("#tp-container").prepend(headerHtml);

.ui-hidden-on-load{display: none;}

.ui-widget-header div{ width: 100% }
使用:这高度依赖于JQuery和数据表.net插入。
