测试APICloud的一段代码

在学习APICloud， 还是需要实践

// 随意切换按钮
    function randomSwitchBtn( tag ) {
    	/*
        if( tag == $api.dom('#footer li.f_0') )return;
        var eFootLis = $api.domAll('#footer li'),
            eHeaderLis = $api.domAll('header li'),
            index = 0;
        for (var i = 0,len = eFootLis.length; i < len; i++) {
            if( tag == eFootLis[i] ){
                index = i;
            }else{
                $api.removeCls(eFootLis[i], 'f_0');
                $api.removeCls(eHeaderLis[i], 'active');
            }
        }
        $api.addCls( eFootLis[index], 'f_0');
        $api.addCls( eHeaderLis[index], 'active');
        api.setFrameGroupIndex({
            name: 'group',
            index: index
        });
        */
       if( tag == $api.dom('#footer li.f_0 a') )return;
       var eFootLis = $api.domAll('#footer li a');
       		eFootLisMyGy = $api.domAll('#footer li');
       		eHeaderLis = $api.domAll('header li'),
            index = 0;
            
       for (var i = 0,len = eFootLis.length; i < len; i++) {
            if( tag == eFootLis[i] ){
                index = i;
            }else{
                $api.removeCls(eFootLisMyGy[i], 'f_0');
                $api.addCls( eFootLisMyGy[i], 'f_c');
                $api.removeCls(eHeaderLis[i], 'active');
            }
        }
        
        //alert(index);
        
        $api.removeCls(eFootLisMyGy[index], 'f_c');
        $api.addCls( eFootLisMyGy[index], 'f_0');
        $api.addCls( eHeaderLis[index], 'active');
        api.setFrameGroupIndex({
            name: 'group',
            index: index
        });
        
    }
