我可以为表添加很多行, 但我不能删除很多行。 我每次连续添加只能删除1行。
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
$("#remCF").on('click',function(){
$(this).parent().parent().remove();
});
});
});
</script>

每页只能有一个唯一ID。将这些ID更改为类,并更改jQuery选择器。
另外,将.on()移到.click()函数之外,因为你只需要设置一次。

$(".addCF").click(function(){
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');

这是html部分......
<form id='students' method='post' name='students' action='index.php'>
<table border="1" cellspacing="0">
<tr>
<th><input class='check_all' type='checkbox' onclick="select_all()"/></th>
<th>S. No</th>
<th>First Name</th>
<th>Last Name</th>
<th>Tamil</th>
<th>English</th>
<th>Computer</th>
<th>Total</th>
</tr>
<tr>
<td><input type='checkbox' class='case'/></td>
<td>1.</td>
<td><input type='text' id='first_name' name='first_name[]'/></td>
<td><input type='text' id='last_name' name='last_name[]'/></td>
<td><input type='text' id='tamil' name='tamil[]'/></td>
<td><input type='text' id='english' name='english[]'/> </td>
<td><input type='text' id='computer' name='computer[]'/></td>
<td><input type='text' id='total' name='total[]'/> </td>
</tr>
</table>
<button type="button" class='delete'>- Delete</button>
<button type="button" class='addmore'>+ Add More</button>
<p>
<input type='submit' name='submit' value='submit' class='but'/></p>
</form>
接下来需要包含jquery ......
<script src='jquery-1.9.1.min.js'></script>
最后添加表行的脚本......
<script>
var i=2;
$(".addmore").on('click',function(){
var data="<tr><td><input type='checkbox' class='case'/></td><td>"+i+".</td>";
data +="<td><input type='text' id='first_name"+i+"' name='first_name[]'/></td> <td><input type='text' id='last_name"+i+"' name='last_name[]'/></td><td><input type='text' id='tamil"+i+"' name='tamil[]'/></td><td><input type='text' id='english"+i+"' name='english[]'/></td><td><input type='text' id='computer"+i+"' name='computer[]'/></td><td><input type='text' id='total"+i+"' name='total[]'/></td></tr>";
$('table').append(data);
i++;
});
</script>
答案 2 :(得分:3)
将ID更改为类:
$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
$(".remCF").on('click',function(){
$(this).parent().parent().remove();
});
答案 3 :(得分:3)
除了其他答案之外,我还希望将删除改进为更通用的内容:
$(this).closest('tr').remove();
这比使用$(this).parent().parent().remove();
要好得多,因为它不依赖于元素的深度。因此,行的结构变得更加灵活。
