Example of JS regular matching Chinese method

This article describes the method of JS regular matching Chinese. Share it for your reference, as follows:

need: Use JS regular method to match and output the Chinese characters in the string "[smile][pray your lips][daily][chilling]".

Sample code:

<script>
var pattern1 = /[\u4e00-\u9fa5]+/g;
var pattern2 = /\[[\u4e00-\u9fa5]+\]/g;
var contents = "[smile][puff the lips][daily][satisfied][cry]";
content = (pattern1);
alert(content);
content = (pattern2);
alert(content);
</script>

Looking at the above content, Chinese character content has been obtained through pattern1 alert content. Then the meaning of pattern2 is to pay attention to points [,]. It’s nothing. It’s a very simple analysis. It’s worth noting that [\u4e00-\u9fa5] is enough to match Chinese.
