JS实现动态表格的添加，修改，删除功能(推荐)
时间：2021-07-25 08:39:56|栏目：JavaScript代码|点击： 次
1. 首先在页面中配置好一个表格框架
<tr> <td>新增参数:</td> <td class="pn-fcontent"><input type="button" value="选择" onclick="openAppParamsPage();"/></td> <td>参数列表:</td> <td class="pn-fcontent"><input type="hidden" id="paramslist" name="paramslist" style="width:190%" height="500"/></td> </tr> <tr> <table id="tab" width="100%" cellspacing="1" cellpadding="0" border="0" style="" class="pn-ltable"> <tr> <td height="20" valign="top" align="center"> 参数名称: </td> <td height="20" valign="top" align="center"> 参数编码: </td> <td height="20" valign="top" align="center"> 参数值: </td> <td id="pos_1" height="20"> 操作 </td> </tr> <tbody id="sortList"></tbody> </table> </tr> <tr> <td align="center" colspan="4"> <input type="submit" class="btn" value="保存" onclick="setParamslist();"/> <input type="button" class="btn" value="返回"/> </td> </tr>
2. 相关JS函数
function setParamslist() {
var tab = document.getElementById("tab");
//表格行数
var rows = tab.rows.length ;
//表格列数
var cells = tab.rows.item(0).cells.length ;
//alert("行数"+rows+"列数"+cells);
var rowData = "";
for(var i=1;i<rows;i++) {
var cellsData = new Array();
for(var j=0;j<cells-1;j++) {
cellsData.push(tab.rows[i].cells[j].innerText);
}
rowData = rowData + "|" + cellsData;
}
document.getElementById("paramslist").value = rowData;
}
//打开相关新增应用参数界面
function openAppParamsPage() {
var param = new Object();
//这个参数一定要传。
param.win = window;
param.id = 100;
param.name = "test";
param.birthday = new Date();
var result = window.showModalDialog("addParamsItem","dialogWidth:500px;dialogHeight:600px;dialogLeft:200px;dialogTop=200px");
//var temp = document.getElementById("paramslist").value;
//document.getElementById("paramslist").value = temp + result;
addSort(result);
}
// 增加应用参数函数
function addSort(data) {
var name = data;
if(name == ""||name==undefined ) {
return;
}
console.log(data);
var params = data.split(",");
var paramName = params[0];
var paramCode = params[1];
var paramValue = params[2];
var row = document.createElement("tr");
row.setAttribute("id", paramCode);
var cell = document.createElement("td");
cell.appendChild(document.createTextNode(paramName));
row.appendChild(cell);
cell = document.createElement("td");
cell.appendChild(document.createTextNode(paramCode));
row.appendChild(cell);
cell = document.createElement("td");
cell.appendChild(document.createTextNode(paramValue));
row.appendChild(cell);
var deleteButton = document.createElement("input");
deleteButton.setAttribute("type", "button");
deleteButton.setAttribute("value", "删除");
deleteButton.onclick = function () { deleteSort(paramCode); };
cell = document.createElement("td");
cell.appendChild(deleteButton);
row.appendChild(cell);
document.getElementById("sortList").appendChild(row);
}
// 删除应用参数函数
function deleteSort(id) {
if (id!=null){
var rowToDelete = document.getElementById(id);
var sortList = document.getElementById("sortList");
sortList.removeChild(rowToDelete);
}
}
附加表格的修改函数
//弹出更新界面相关信息
function updateSort(id) {
if (id!=null){
var row = document.getElementById(id);
//alert("row is " + row.cells[0].innerHTML);
var id = row.cells[0].innerHTML;
var paramName = row.cells[1].innerHTML;
var paramCode = row.cells[2].innerHTML;
var paramValue = row.cells[3].innerHTML;
var param = new Object();
//这个参数一定要传。
param.win = window;
param.id = 100;
param.name = "test";
param.birthday = new Date();
var result = window.showModalDialog(baseUrl + "app/updateParamsItem?id=" + id + "¶mName=" + paramName + "¶mCode=" + paramCode + "¶mValue=" + paramValue,
"dialogWidth:500px;dialogHeight:600px;dialogLeft:200px;dialogTop=200px");
var arr = result.split(",");
row.cells[0].innerHTML = arr[0];
row.cells[1].innerHTML = arr[1];
row.cells[2].innerHTML = arr[2];
row.cells[3].innerHTML = arr[3];
}
}
3. 弹出框页面，新增或者修改参数，并回写相关数据。

var result = paramName.value + "," + paramCode.value + "," + paramValue.value;
window.returnValue = result;
window.close();
