javascript - 如何在jquery中访问id attr中的特殊字符

Question

我有像

这样的元素

<div id = "node-1-@" >
  <div class="region">
    accessData
  </div>
</div> 

JavaScript

var data = $("#node-1-@ .region");
console.log(data.html())

这会产生类似的错误

Syntax error, unrecognized expression: #node-1-@

Answer 1

尝试 var data = $("#node-1-\\@ .region");

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