我正在为一个FAQ创建一个单词过滤器，现在它工作，但只与第一个单词，我应该使用什么正则表达式来过滤任何单词?
我无法将单词传递给pattern，因为它们来自Wordpress中的高级自定义字段。
我已经尝试了很多方法，但我不是一个regex专家。
Thanks in advance
$(".search-field").keyup(function() {
var pattern = new RegExp(
"^" + this.value.replace(/([\(){}|-])/g, "\$1"),
"i"
);
$(".js-list-faq li a")
.hide()
.filter(function() {
return !!$(this).text().match(pattern);
})
.show();

</html>你的正则表达式错误，"^">
用这个代替:
...
var pattern = new RegExp(
this.value.replace(/([\(){}|-])/g, "\$1"), 'i'
);
...
