动态表格，通过按钮增加行，删除时删除选择的checkbox那一行

<script>

//给table增加一行

function addTableRow() {

var table1 = document.getElementById('table1');

var cloneTab = document.getElementById('table2');

//alert(cloneTab.firstChild.firstChild.innerHTML);

//alert(cloneTab.firstChild.firstChild.cloneNode(true).innerHTML);

table1.firstChild.appendChild(cloneTab.firstChild.firstChild.cloneNode(true));

var v= table1.firstChild.childNodes;

var len = v.length;

for(var i=1;i<len;i++){

v[i].childNodes[0].firstChild.id=i;//给第一个单元格id赋值

}

}

//给table删除一行

function delTableRow(){

var table1 = document.getElementById('table1');

var isChecked = document.getElementsByName('isChecked');

var len = isChecked.length;

for(var i=len-1;i>=0;i--){

if(isChecked[i].checked==true){

table1.firstChild.removeChild(isChecked[i].parentNode.parentNode);

//alert(isChecked[i].id);

//alert(isChecked[i].parentNode.parentNode.innerHTML);

}

}

}

</script>
