javascript - 带有类名和值的目标输入

Question

如何通过类名和值来定位特定输入？

<input type="checkbox" class="something" value="1">
<input type="checkbox" class="something" value="2">
<input type="checkbox" class="something" value="3">

目标类名+值2:

$('target classname = something, value = 2').prop('checked', true);

Answer 1

$('input[class=something][value=2]').prop('checked', true);

$('input[class=something][value=2]').prop('checked', true);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="something" value="1">
<input type="checkbox" class="something" value="2">
<input type="checkbox" class="something" value="3">
