对表格元素操作的两种方式

选中表格的的一行元素
function dblGetBody(){//双击查看详细内容
        var e=WT.e.fix(e),_e=e.t;
        while(_e.tagName != 'TABLE'){
            if(_e.attr('opt')){
                break;
            }
            if(_e.tagName == 'TR' && _e.attr('idx')){
                createTips('查看');
                newsQuery({id:_e.attr('idx')},function(data){
                    inputDisable();
                    dataView(data[0]);
                });
            }
            _e = _e.pn();
        }
    }

选中表格中某一个元素
function newsOpt(){
        var e=WT.e.fix(e),_e=e.t;
        switch(_e.attr('opt')){
            case 'newsPpl_edit':
                createTips('修改');
                newsQuery({id:_e.pn(2).attr('idx')},function(data){
                    dataView(data[0]);
                    $('newsPpl_edit_btns').dc('dn');
                    $('newsPpl_editRecovery_btn').evt('click',function(){
                        dataView(JSON.parse(WT.ls.get('newsPplInputDate')),true);
                    });
                    $('newsPpl_edit_btn').evt('click',function(){
                        var param = getInputVal();
                        param.id = _e.pn(2).attr('idx')
                        newsEdit(param);
                    });
                    $('newsPpl_edit_close_btn').evt('click',function(){
                        var param = getInputVal();
                        param.id = _e.pn(2).attr('idx')
                        newsEdit(param);
                        settingTips.r();
                        newsBody = null;
                        newsBrief = null;
                        $('tips_mask').hide();
                    });
                    $('clear_edit_btn').evt('click',function(){
                        clearInputVal();
                    });
                });
            break;
            case 'newsPpl_del':
                $('newsPpl_del').dc('dn');
                $('mask').style.display = 'block';
                $('newsPpl_delTitle').ht(_e.attr('tips'));
                $('newsPpl_del_no').evt('click',function(){
                    $('newsPpl_del').ac('dn');
                    $('mask').style.display = 'none';
                });
                $('newsPpl_del_yes').evt('click',function(){
                    newsDel({id:_e.pn(2).attr('idx')});
                });
            break;
        }        
    }
