js实现对table动态添加、删除和更新的方法_javascript技巧

代码如下:







function addRow() { //增加一行
var tableObj = document.getElementById('myTable');
var rowNums = tableObj.rows.length;
var newRow = tableObj.insertRow(rowNums);
var col1 = newRow.insertCell(0);
col1.innerHTML = "幸福从天而降";
var col2 = newRow.insertCell(1);
col2.innerHTML = "$18.5";
col2.align = "center";
var divInfo = document.getElementById('displayInfo');
divInfo.innerHTML = "添加商品成功";
}
function delRow() { //删除第二行
document.getElementById('myTable').deleteRow(1);
var divInfo = document.getElementById('displayInfo');
divInfo.innerHTML = "删除商品成功";
}
function updateRow() { //更新行的信息
var uRow = document.getElementById('myTable').rows[0];
uRow.className = "title";
}
