这里有新鲜出炉的Javascript教程，程序狗速度看过来！
JavaScript客户端脚本语言
Javascript 是一种由Netscape的LiveScript发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言，主要目的是为了解决服务器端语言，比如Perl，遗留的速度问题，为客户提供更流畅的浏览效果。
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。
