下面用js實(shí)現(xiàn)可以生成用戶(hù)所需行數(shù)的表格，具體步驟及效果圖如下，感興趣的朋友，可以參考下哈，希望對(duì)大家有所幫助

下面用js實(shí)現(xiàn)可以生成用戶(hù)所需行數(shù)的表格。
1.首先在body中填入下列代碼，獲取用戶(hù)填入的行數(shù)值

 
<table> 
<tr> 
<td>動(dòng)態(tài)生成表格</td> 
<td><input id="Cold" type="text" class="input" size="10" name="Num"/>行</td> 
</tr> 
</table> 
</br> 
<input name="" type="button" value="生成" class="buttton" onclick="table()"/></br> 
</br> 
<div id="div1" style="display: none" mce_style="display: none"> 
<div id="table1"></div> 
</div> 
<div id="errmsg1" class="formmsg"></div> 

效果如下圖所示：

2.header中添加js代碼

復(fù)制代碼代碼如下:

 
<script> 
function table() { 
if (document.getElementById("Num").value == "" || document.getElementById("Num").value.search("^[0-9]*$") == -1) { 
document.getElementById("errmsg1").style.display = "block";//判斷Num是否為空或不是數(shù)字 提示錯(cuò)誤 
document.getElementById("errmsg1").innerHTML = "提示信息：行數(shù)為空或不是數(shù)字！"; 
} 
else { 
document.getElementById("errmsg1").style.display = "none";//隱藏提示信息 
var Num = parseInt(document.getElementById("Num").value); //獲取行數(shù) 
var flag = true; 
var data = ""; 
data += " <table >"; 
data += " <tr>" + 
"<td >we are</td>" + 
"<td >zhuzhu</td>" + 
"<td >dudu</td>" + 
"</tr>" ; 
for (var i = 1; i <= Num; i++) { 
data += "<tr >"; 
data += "<td>" + i + "</td>"; 
data += "<td><input name='ColdDay"+i+"' type='text' class='input'></td>"; 
data += "<td><input name='ColdCureMethod"+i+"' type='text' class='input'></td>"; 
data += "</tr>"; 
} 
data += "</table>"; 
document.getElementById("div1").style.display = "block"; 
document.getElementById("table1").innerHTML = data; 
} 
} 
</script> 

生成效果如下：

3.所有代碼如下

復(fù)制代碼代碼如下:

 
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%>

function table() { 
if (document.getElementById("Num").value == "" || document.getElementById("Num").value.search("^[0-9]*$") == -1) { 
document.getElementById("errmsg1").style.display = "block";//判斷payNum是否為空或不是數(shù)字 提示錯(cuò)誤 
document.getElementById("errmsg1").innerHTML = "提示信息：行數(shù)為空或不是數(shù)字！"; 
} 
else { 
document.getElementById("errmsg1").style.display = "none";//隱藏提示信息 
var Num = parseInt(document.getElementById("Num").value); //獲取分期數(shù) 
var flag = true; 
var data = ""; 
data += " <table >"; 
data += " <tr>" + 
"<td >we are</td>" +
