This time I will bring you the method of dynamically operating table rows in jquery (with code). What are the precautions for dynamically operating table rows in jquery? Here is a practical case, let’s take a look.
<script src="jquery/jquery-1.3.1.js"></script>
<style type="text/css">
body{background:#FFFFFF;}
</style>
</head>
<body>
<script>
$(function(){
var show_count = 20; //要显示的条数
var count = $("input:text").val(); //递增的开始值，这里是你的ID
var fin_count = parseInt(count) + (show_count-1); //结束递增的条件
$("#btn_addtr").click(function(){
if(count < fin_count) //点击时候，如果当前的数字小于递增结束的条件
{
$("tr:eq(1)").clone().appendTo("table"); //在表格后面添加一行
$("tr:last td input:first").val(++count); //改变添加的行的ID值。
}
});
});
function deltr(){
var length=$("tr").length;
if(length<=2){
alert("至少保留一行");
}else{
$("tr:last").remove();
}
}
</script>
<input type="button" id="btn_addtr" value="增行">
<table id="dynamicTable" width="700" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="30" align="center" bgcolor="#CCCCCC">ID</td>
<td align="center" bgcolor="#CCCCCC">Username</td>
<td align="center" bgcolor="#CCCCCC">Usertype</td>
<td align="center" bgcolor="#CCCCCC">Other</td>
<td></td>
</tr>
<tr>
<td height="30" align="center"><input type="text" size="2" value="1" /></td>
<td align="center"><input type="text" name="username" /></td>
<td align="center">
<select name="type">
<option value="1">Administrator</option>
<option value="2">Guest</option>
</select>
</td>
<td align="center"><input type="text" name="username2" /></td>
<td><input type="button" id="btn_deltr" onclick="deltr()" value="删行"></td>
</tr>
</table>
