我正在使用下面的脚本进行HTML网站搜索。
我遇到的问题是,当我希望它在整个XML中独立搜索单词时,它一起搜索单词作为一个短语。即如果有人进入“数字制作人”,它会搜索“数字制作人”,而不是单独搜索“数字制作人”和“制作人”。
非常感谢任何帮助实现这一目标的帮助!

答案 0 :(得分:1)
由于您正在使用正则表达式,您可以做的是用OR运算符|
替换原始搜索字符串中的所有空格(&lt; - 它是一个管道[shift + \],以防它很难告诉)。您可以在keyword = keyword.replace(" ", "|");
var exp = new RegExp(keyword,"gi");
行
请告诉我这是否适合您,如果有意义的话:)
