How can I select a hidden field by value?
提问by flesh
I have the following HTML generated by an ASP.NET repeater:
我有以下由 ASP.NET 中继器生成的 HTML:
<table>
<tr>
<td><input type="hidden" name="ItemId" id="ItemId" value="3" /></td>
<td>Terry</td>
<td>Deleted</td>
<td>Low</td>
<td>Jun 21</td>
</tr>
<!-- rows repeat -->
</table>
How do I select a particular hidden field by value, so that I can then manipulate the columns next to it?

Using jQuery Selectors, you can target your element by a certain attribute matching the desired value:
使用jQuery Selectors,您可以通过匹配所需值的特定属性来定位您的元素:
$('input[value="Whatever"]');
This way you are targeting an input
element, by the attribute value
that is equal to the desired value.
通过这种方式,您可以input
通过value
等于所需值的属性来定位元素。
EDIT 5/14/2013:According to an answer below, this no longer works as of jQuery 1.9.

Note: Since jQuery 1.9 the input[value="banana"] selector is no longer valid, because 'value' of the input is technically not an attribute. You need to use the (far more difficult to read) .filter
注意:从 jQuery 1.9 开始, input[value="banana"] 选择器不再有效,因为输入的 'value' 在技术上不是一个属性。您需要使用(更难阅读) .filter
E.g.
例如
$("input").filter(function () {
return this.value === "banana";
});
