按值选择输入？ [英] select an input by value?

问题描述

我在页面上有一堆隐藏的输入...

I have a bunch of hidden inputs on a page...

<input type='hidden' name='thing' value='' />;
<input type='hidden' name='thing' value='' />;
<input type='hidden' name='thing' value='' />;

等...

每次输入可以有任意值。

Each input can have an arbitrary value.

在jquery中，检查其中一个输入是否已设置为已知的特定值的最佳方法是什么？

In jquery, what is the best way to check if one of these inputs has been set to a known, specific value?

谢谢

推荐答案

如果您知道value属性设置为特定值你可以使用属性选择器

If you know that the value attribute is set to a specific value you can use the attribute selector

$('input[value="something"]');

编辑添加：

您可能希望将attr选择器链接为输入[name =thing] [value =something] 并且@Drackir是对的，您可以通过匹配的 length 属性测试是否匹配一个或多个元素。

you may want to chain the attr selector as input[name="thing"][value="something"] and @Drackir is right, you can test if it matches by whether one or more elements is in the set via the length property of the match.
