You need to enclose special characters in quotes when using a attribute based selector.
使用基于属性的选择器时，您需要将特殊字符括在引号中。
if ($('ul li a[href="' + id + '"]').length) {
Your version of selector would result
您的选择器版本将导致
if ($("ul li a[href=#!...]").length) {
The #!will throw unrecognized expression.
该#!会抛出无法识别的表达。
My version where the ""escape the characters
我的版本在哪里""转义字符
if ($('ul li a[href="#!..."]').length) {
