<body>
<form id="myForm" method="get" action="./" />
<label>Text Box #1a: <input type="text" name="txt1" id="txt1" /></label>
<p>
<input type="button" value="Add Textbox" onClick="addTextBox(this.form,this.parentNode) " />
<input type="button" value="Remove Textbox" onClick="removeTextBox(this.form)" />
</p>
<p><input type="Submit" value="Submit" /></p>
</form>
</body>
</html>
用easyUI属性columns:[[
{field:'b',title:'修改',width:190,formatter:function(row){
return '<input id="sage" name ="age">'
}
]]
可以实现动态每列自动生成文本框，希望采纳。
