触发事件的方法：编辑用户组成员

function editGroupUser(id) {
	$
			.ajax( {
				type : "POST",
				url : "/group/groupUserquery.json",
				dataType : "json",
				data : "id=" + id,
				success : function(data) {


					/**
					 * 这个组已经存在的成员
					 */
					var gxHtml = "<select name='myGroupUser'  border='1'  multiple  style='width:200px;height:285px;' >";
					$.each(data.alreadylinkUser, function(i, noCo) {
						gxHtml += "<option value=" + noCo.userId + ">"
								+ noCo.userName + "</option>";
					});
					gxHtml += "</select>";
					$("#myGroupUsers").html(gxHtml);

					/**
					 * 还没有分组的成员

					var wgxHtml = "<select name='noGroupUser'  border='1'  multiple  style='width:200px;height:285px; ' >";
					$.each(data.noLinkUser, function(i, noCo) {

					$("#myGroupName").text(data.group.groupName);
					$("#myGroupId").val(data.group.id);
										
					$("#dialog_form_editGroupUser").dialog("open");

				},
				error : function(XMLHttpRequest, textStatus, errorThrown) {
					alert("错误状态：" + textStatus + "\n错误信息：" + errorThrown);
				}
			});
