jQuery 遍历名称属性包含方括号的复选框

Question

我有这些复选框：

<input type="checkbox" class="ids" name="ids[]" value="2">
<input type="checkbox" class="ids" name="ids[]" value="3">
<input type="checkbox" class="ids" name="ids[]" value="4">
<input type="checkbox" class="ids" name="ids[]" value="5">
<input type="checkbox" class="ids" name="ids[]" value="6">

我的问题是 jquery，我将如何在提交表单时循环访问 ids[]？

$("#form").submit(function(e) {
  //Loop throught ids[] 
});

我试过这个：

$('input[type=checkbox][name=ids[]]').each(function () {   
  console.log("Here");
});

但是没用

您的选择器无效。您应该使用 \.

转义 []

To use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[\]^`{|}~ ) as a literal part of a name, it must be escaped with with two backslashes: \. documentation

$('input[type=checkbox][name=ids\[\]]').each(function(){
  console.log(this.value);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="ids" name="ids[]" value="2">
<input type="checkbox" class="ids" name="ids[]" value="3">
<input type="checkbox" class="ids" name="ids[]" value="4">
<input type="checkbox" class="ids" name="ids[]" value="5">
<input type="checkbox" class="ids" name="ids[]" value="6">
