javascript - 使用特殊字符进行 Optgroup 过滤

Question

var branches = $('#branch_name').html();
var filtrate = optgroup[label="Abe's Milk"]
var options = $(branches).filter(filtrate).html();

我明白了:

throw new Error ( "Syntax error, unrecognized expression: " + msg );

但是如果我输入:

var filtrate = optgroup[label="Abes Milk"]

没有错误。

我尝试使用正则表达式自动转义 Abe's 中的单引号，但这也失败了，因为没有 optgroup 与 Abe\'s Milk 匹配。

请帮忙。谢谢!

Answer 1

I tried automatically escaping the single quote in Abe's with a regular expression, but this failed as well because no optgroup matched Abe\'s Milk.

尝试:

optgroup[label="Abe\'s Milk"]
