Javascript名称数组输入选择器(name [sometext])

Question

如何在jQuery中正确选择这样的命名输入而不分配ID？

<input name="person[first]" type="hidden">
<input name="person[last]" type="hidden">

// Seems to be acting on multiple hidden elements instead of this named one
// This sets the value of both of those hidden elements in some cases
$("input[type=hidden][name=person[first]]").val('Test');

// So I've changed it to this. Is there a better way?
$("input[name=person[first]]").val('Test');

将属性值放在引号中...

$("input[type=hidden][name='person[first]']").val();
   // ---------------------^-------------^

来自属性等于选择器的文档 ......

属性属性名称.

value属性值.可以是不带引号的单个单词或带引号的字符串.

由于您不仅仅有一个单词,因此应该引用它.
