easyui tabs按照标签页ID进行检索

默认的tabs只能根据index或者title检索，现在进行修改，看到的一个不错的教程，非改源代码，只要贴在js文件里就能用

$.extend($.fn.tabs.methods, {
    getTabById: function(jq,id) {
        var tabs = $.data(jq[0], 'tabs').tabs;
        for(var i=0; ivar tab = tabs[i];
            if (tab.panel('options').id == id){
                return tab;
            }
        }
        return null;
    },
    selectById:function(jq,id) {
        return jq.each(function() {
            var state = $.data(this, 'tabs');
            var opts = state.options;
            var tabs = state.tabs;
            var selectHis = state.selectHis;
            if (tabs.length == 0) {return;}
            var panel = $(this).tabs('getTabById',id); // get the panel to be activated 
            if (!panel){return}
            var selected = $(this).tabs('getSelected');
            if (selected){
                if (panel[0] == selected[0]){return}
                $(this).tabs('unselect',$(this).tabs('getTabIndex',selected));
                if (!selected.panel('options').closed){return}
            }
            panel.panel('open');
            var title = panel.panel('options').title;        // the panel title 
            selectHis.push(title);        // push select history 
            var tab = panel.panel('options').tab;        // get the tab object 
            tab.addClass('tabs-selected');
            // scroll the tab to center position if required. 
            var wrap = $(this).find('>div.tabs-header>div.tabs-wrap');
            var left = tab.position().left;
            var right = left + tab.outerWidth();
            if (left < 0 || right > wrap.width()){
                var deltaX = left - (wrap.width()-tab.width()) / 2;
                $(this).tabs('scrollBy', deltaX);
            } else {
                $(this).tabs('scrollBy', 0);
            }
            $(this).tabs('resize');
            opts.onSelect.call(this, title, $(this).tabs('getTabIndex',panel));
        });
    },
    existsById:function(jq,id){
        return $(jq[0]).tabs('getTabById',id) != null;
    }
});

使用方法：

var tab = $("tabs").tabs("selectById","tabId");
var isExist = $("tabs").tabs("existsById","tabId");

或者

 var t = top.$('#index_tabs');
 t.tabs("existsById","tabId")
