小编Pau*_*uck的帖子

<form action="next.php" method="post">
<table>
    <tr>
      <td>Paul</td>
      <td>Attuck</td>
      <td>paulattuck@yahoo.com</td>
      <td><input type="checkbox" name="list[]" value="paulattuck@yahoo.com" /></td>
    </tr>
    <tr>
      <td>James</td>
      <td>Bond</td>
      <td>jamesbond@yahoo.com</td>
      <td><input type="checkbox" name="list[]" value="jamesbond@yahoo.com" /></td>
    </tr>
    <tr>
      <td>Name</td>
      <td>Last</td>
      <td>lastname@yahoo.com</td>
      <td><input type="checkbox" name="list[]" value="lastname@yahoo.com" /></td>
    </tr>
</table>
    <input type="submit" name="submit" value="submit" />
</form>

如果我选中所有复选框并将表单发送到next.php我可以:

print_r($_POST['tags']);
// output
Array
(
    [0] => paulattuck@yahoo.com
    [1] => jamesbond@yahoo.com
    [2] => lastname@yahoo.com
)

我怎么做:

Array
    (
        [0] => array ([0] => Paul
                      [1] => Attuck
                      [2] => paulattuck@yahoo.com)
        [1] => array ([0] => James …

<input type="text" id="text">
<span id="click">click</span>


$("#click").click(function(){

    if($("#text").val().length < 1){
       alert("click is empty!");
       false;
    }

    alert("ok");
})

为什么在这个例子中如果$ click length == 0我有警报点击是空的(这很好)和下一个警报ok(不好) - 为什么false不会停止脚本？我知道 - 我可以使用其他,但可能会停止虚假？

<span id="aaa_1_bbb">aaa</span>
<span id="aaa_2_bbb">aaa</span>
<span id="aaa_3_bbb">aaa</span>
<span id="aaa_4_bbb">aaa</span>
<span id="aaa_5_bbb">aaa</span>
<span id="aaa_6_bbb">aaa</span>
<span id="bbb_1_bbb">aaa</span>
<span id="ccc_1_bbb">aaa</span>
<span id="ddd_1_bbb">aaa</span>
<span id="aaa_1_xxx">aaa</span>

$('span[id="aaa_*_bbb"]').css('background-color', 'red');

我该如何修改这个jQuery？我想只为aaa _*_ bbb ID添加css(background-color:red).*=数字

id | words                            | other
1  | lorem ipsum                      | dsf
2  | Lorem Ipsum is simply dummy text | sads
3  | simply dummy text                | sdf
4  | Lorem Ipsum  text                | sdfsdf
5  | simply dummy Lorem               | asddasd 

我选择单词*。我如何计算这个查询答案中有多少个单词？在这个例子中应该是17。我使用PHP和Doctrine。

<table><tr>
<td class="delete" new="1">1</td>
<td class="delete" new="2">2</td>
<td class="delete" new="">3</td>
<td class="delete" new="5">4</td>
<td class="delete" new="6">5</td>
</tr>
</table>

$('.delete').remove();

如何删除TD属性new =""(null)？
