js 改变Tab

新增行：

var tab=document.getElementById("tab");

var DataRows=tab.rows;//类似数组的Rows 
 var dataRowLength=DataRows.length+1;
  var  newTR = tab1.insertRow(dataRowLength);
                              var values=["发货单少的",orderIsbn,orderTitle,"",orderAuthor,"",orderPublisher,"",orderPrice,"",orderOrderQnty,"",orderMayang,null];
                              for(var i=0;i<values.length;i++){
                                 newTD=newTR.insertCell(i);
                                 newTD.align="center";
                                  newTD.innerHTML="<span id='sp_"+fileds[i]+"_"+dataRowLength+"'>"+values[i]+"</span>";
                         }

 

删除行：

var tab1=document.getElementById("tab1");
tab1.deleteRow(removeIndex);
