以下是使用javascript对表格的添加行,删除行,进行操作..
具体代码如下:
style样式代码:
<style>
.displayStyle{
background-color:00FFFF;
}
.hideStyle{
background-color:#FFFFF;
}
.onClickStyle{
background-color:00FF00;
}
a{
color:red;
}
a:hover{
color:green;
}
</style>
javascript代码:
<script>
var selectRow=null;
//单击时,改变样式;
function onClickChangeStyle(obj){
//获取表格对象;
var tab = document.getElementById("tab");
//获取当前行选择下标;
var currentRowIndex = obj.rowIndex;
//获取表格所有行数;
var tablRows = tab.rows.length;
//获取表格第一行,第一列的值;
//var firstCellValue = tab.rows[0].cells[0].innerHTML;
//获取表格的第一行，第一列的第一个元素的值;
//var firstChildValue = tab.rows[0].cells[0].firstChild.value;
//循环表格的所有行;并且选择的当前行，改变背景颜色；
for(var i = 1;i<tablRows;i=i+1){
if(currentRowIndex == i){
//为选中的当前，设置css样式;
selectRow = tab.rows[i];
tab.rows[i].className= "onClickStyle";
}else{
//把没有选中的行的背景样式设置为白色;
tab.rows[i].className= "hideStyle";
}
}
}
//鼠标移入时，改变颜色;
function onmouseOverMethod(selectThis){
selectThis.className="displayStyle";
if(selectRow==selectThis){
selectThis.className="onClickStyle";
}
}
//鼠标移除时，改变背景颜色;
function onmouseOutMethod(selectThis){
selectThis.className="hideStyle";
if(selectRow == selectThis){
selectThis.className="onClickStyle";
}
}
//添加行;
function addRow(){
var tab = document.getElementById('tab');
var rowIndex = tab.rows.length+1;
//添加一行;
var tr = tab.insertRow();
tr.onmouseover = tr.className="displayStyle" ;
tr.onmouseout = tr.className="hideStyle" ;
tr.onclick=function (){this.className="onClickChangeStyle(this)";}
var td1 = tr.insertCell();
var td2 = tr.insertCell();
var td3 = tr.insertCell();
var td4 = tr.insertCell();
var td5 = tr.insertCell();
var td6 = tr.insertCell();
var td7 = tr.insertCell();
td1.innerHTML = "<input type='hidden'/><input type='checkbox' value = '1'>";
td2.innerHTML = ""+rowIndex;
td3.innerHTML = "测试";
td4.innerHTML = "22";
td5.innerHTML = "无地址";
td6.innerHTML = "<a href='#' onclick='addRow()'>添加</a>";
td7.innerHTML = "<a href='#' onclick='deleteRow(this)'>删除</a>";
//初始化行;
initRows(tab);
}
//初始化行,设置序列号;
function initRows(tab){
var tabRows = tab.rows.length;
for(var i = 0;i<tabRows.length;i++){
tab.rows[i].cells[0].firstChild.value=i;
}
}
//删除行;(obj代表连接对象)
function deleteRow(obj){
var tab = document.getElementById('tab');
//获取tr对象;
var tr = obj.parentNode.parentNode;
if(tab.rows.length>2){
//tr.parentNode，指的是，table对象;移除子节点;
tr.parentNode.removeChild(tr);
}
//重新生成行号;
initRows(document.getElementById('tab'));
}
</script>
