js动态生成指定行数的表格
人气:0
下面用js实现可以生成用户所需行数的表格。
1.首先在body中填入下列代码，获取用户填入的行数值
<table>
<tr>
<td>动态生成表格</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>
效果如下图所示：
2.header中添加js代码
<script>
function table() {
if (document.getElementById("Num").value == "" || document.getElementById("Num").value.search("^[0-9]*$") == -1) {
document.getElementById("errmsg1").style.display = "block";//判断Num是否为空或不是数字 提示错误
document.getElementById("errmsg1").innerHTML = "提示信息：行数为空或不是数字！";
}
else {
document.getElementById("errmsg1").style.display = "none";//隐藏提示信息
var Num = parseInt(document.getElementById("Num").value); //获取行数
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：
