This time I will bring you jQuery to implement fuzzy matching query of HTML page text box (with code), jQuery to implement fuzzy matching query of HTML page text box What are the precautions , the following is a practical case, one Get up and take a look.
This function needs to be used in the project. I have used Combobox in EasyUI and searched for corresponding solutions online. However, they are not suitable for my project because I still like relatively pure things. I wrote one myself. It is relatively simple, but still usable. I have already used it in my project. I made a small demo for record. If necessary, just copy the code and modify it.
Next is the code, pure html css jquery:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
