如果td标签使用javascript具有NIL值,我目前遇到隐藏tr标签的问题,下面是表格的代码,它出现在第3个表格中,因为我正在开发Chrome扩展程序,这对于定位它很重要
这是我在jquery中尝试过但我需要在javascript中执行此操作:
$('tr').each(function(){
var tr = $(this);
if (tr.find('td:eq(0)').text()=="NIL"
&& tr.find('td:eq(1)').text()=="NIL"
&& tr.find('td:eq(2)').text()=="NIL"
) tr.addClass('hidden');
});
这是表格代码:
<tr>
<td bgcolor=#5A768D width="22%" height="30" rowspan=5 valign=top>
<font color=#FFFFFF>Assignments</font>
</td>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
<tr>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
<tr>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
<tr>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
<tr>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
</table>
答案 0 :(得分:0)
这就是你想要的:
$("table td:contains('NIL')").closest("tr").css("color", "red");
/* ABOVE HERE IS JUST FOR DEMO CHANGING OF COLOR
BUT USE FOLLOWING TO HIDE
$("table td:contains('NIL')").closest("tr").hide();
*/
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<table>
<tr>
<td bgcolor=#5A768D width="22%" height="30" rowspan=6 valign=top>
<font>Assignments</font>
</td>
<td bgcolor='#EDEADE' width="76%" height="30">
NIL
</td>
</tr>
<tr>
<td bgcolor='#EDEADE' width="76%" height="30">
