easyui-tabs扩展根据自定义属性打开页签

1.增加扩展
<script type="text/javascript" >
/**
* @author {kexb} easyui-tab扩展根据id切换页面
*/
$.extend($.fn.tabs.methods, {
getTabById: function (jq, id) {
var tabs = $.data(jq[0], 'tabs').tabs;
for (var i = 0; i < tabs.length; i++) {
var tab = tabs[i];
if (tab.panel('options').id == id) {
return tab;
}
}
return null;
},
selectById: function (jq, id) {
var tab;
var tabs = $.data(jq[0], 'tabs').tabs;
for (var i = 0; i < tabs.length; i++) {
tab = tabs[i];
if (tab.panel('options').id == id) {
break;
}
}
if (tab != undefined)  {

var curTabIndex = $("#tabs").tabs("getTabIndex", tab);
$('#tabs').tabs('select', curTabIndex);
}

},
existsById: function (jq, id) {
return jq.tabs('getTabById', id) != null;
}
});
</script>
2.点击事件open方法
function Open(text, url, id) {
var tabId = ReplaceAll(url, '/','');
var h = ComputGridHeight();
if (url == "null" || url == "" || url == "") {
return;
}
if ($("#tabs").tabs("existsById", tabId)) {

$("#tabs").tabs("selectById", tabId);
}
else
{

if (url.indexOf("?") < 0) {
url += "?_menuId=" + id;
}
else {
url += "&_menuId=" + id;
}

$('#tabs').tabs('add', {
id:tabId,
title: text,
closable: true,
content: createTabContent(url, h),
url: url
});
}
}
