㈠ 只用js如何實現表格內容的動態修改
<body>
<tableid='test'>//定義一個table
<tr>
<td></td><td></td>
</tr>
</table>
<script>
vartb=document.getElementById('test');//獲取表格的dom節點
vartd=tb.rows[0].cells[0];//獲取0行0列的td單元格
td.innerHTML='222';//動態修改表格的內容為222
</script>
</body>
思路:
1、獲取表格的dom節點
2、通過rows和cells定位td單元格
3、通過修改innerHTML
JS實現動態表格的新增,修改,刪除操作
一、相關JS函數
function setParamslist() {
var tab = document.getElementById("tab");
//表格行數
var rows = tab.rows.length ;
//表格列數
var cells = tab.rows.item(0).cells.length ;
//alert("行數"+rows+"列數"+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;
}
//打開相關新增應用參數界面
function openAppParamsPage() {
var param = new Object();
//這個參數一定要傳。
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);
}
// 增加應用參數函數
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", "刪除");
deleteButton.onclick = function () { deleteSort(paramCode); };
cell = document.createElement("td");
cell.appendChild(deleteButton);
row.appendChild(cell);
document.getElementById("sortList").appendChild(row);
}
// 刪除應用參數函數
function deleteSort(id) {
if (id!=null){
var rowToDelete = document.getElementById(id);
var sortList = document.getElementById("sortList");
sortList.removeChild(rowToDelete);
}
}
二、彈出框頁面,新增或者修改參數,並回寫相關數據。

㈡ js動態改變tab背景圖片。求大神賜教,jquery做出來也行。
樣式部分:
.selected {background-image: url('...')}
頁面部分:
<ul id="tab">
<li class="selected">1</li>
<li>2</li>
<li>3</li>
</ul>
js部分:
jQuery('#tab li').click(function(){
jQuery('#tab li').removeClass('selected');
jQuery(this).addClass('selected');
});
