js 操作table
最近把系统前台页面做点功能优化，好几年没写过js了，头顿时很大，经过一系列狂整，总算给做出来了。//删除行
function deleteCurrentRow(obj){
if(confirm("确实要删除吗?")) {
var tr=obj.parentNode.parentNode;
var tbody=tr.parentNode;
tbody.removeChild(tr);
}else{
}
}
table 行上移下移
//上移
function moveUp(src)
{
//上移一行
var rowIndex=src.parentElement.parentElement.rowIndex;
if (rowIndex>=2)
change_row(rowIndex-1,rowIndex);
}
function moveDown(src){
//下移一行
var rowIndex=src.parentElement.parentElement.rowIndex;
var tl = document.getElementById("categoryTable");
if (rowIndex<tl.rows.length-1){
change_row(rowIndex+1,rowIndex);
}
}
function change_row(line1,line2)
{
//执行交换
categoryTable.rows.swapNode(categoryTable.rows);
}
//删除table所有行
function delAllMyRow(){
var mytable = document.getElementById("mybody");
var rowlen=mytable.rows.length;
for(var i=rowlen-1;i>=0;i--){
mytable.deleteRow(i);
}
}
往table 里面插入一行
function selectedChargePackage(value) {
var tab = window.parent.frames.frame1.document.getElementById("categoryTable") ;
//表格行数
var rows = tab.rows.length ;
//添加一行
var newTr =window.parent.frames.frame1.document.getElementById("mybody").insertRow();
//表格列数
// var cells = tab.rows.item(0).cells.length ;
// alert("行数"+rows+"列数"+cells);
//添加四列
var newTd0 = newTr.insertCell();
var newTd1 = newTr.insertCell();
var newTd2 = newTr.insertCell();
var newTd3 = newTr.insertCell();
//设置列内容和属性
newTd0.innerHTML= rows;
newTd1.innerHTML= idValue + tempArray + ",";
newTd2.innerHTML= nameValue + tempArray + ",";
newTd3.innerHTML ="<a href='#' onclick='moveUp(this)' cellpadding='3' cellspacing='1' bgcolor='#c7dffc' style='margin-top:5px; margin-bottom:5px;'>上移</a> " +
"<a href='#' onclick='moveDown(this)' cellpadding='3' cellspacing='1' bgcolor='#c7dffc' style='margin-top:5px; margin-bottom:5px;'>下移</a> " +
"<a href='#' onclick='deleteCurrentRow(this)'cellpadding='3' cellspacing='1' bgcolor='#c7dffc' style='margin-top:5px; margin-bottom:5px;'>删除</a>";
}
获取table 指定行和列的数据
function submitChargePackage() {
var categoryTable = document.getElementById("mybody");
var rows=categoryTable.rows;
// alert("行数:" + rows.length);
for(var i=0;i<rows.length;i++){
// var uu = rows.cells.length;
//alert(rows.cells.innerHTML);
idList = rows.cells.innerHTML;
nameList = rows.cells.innerHTML;
chargePackageIdList = chargePackageIdList + idList;
chargePackageNameList = chargePackageNameList + nameList;
}
}
