JS to realize The imitation Baidu input box automatic matching function example code font: [Increase decrease] type: Reprint

This article is mainly for the JS implementation of Baidu input box automatic matching function of the sample code is introduced, the need for friends can come to the reference, I hope to help you

Now many sites have this effect, in the text box to enter a character, the bottom will come out of the matching content, this code demonstrates how this function is done, of course, this is a static, you can read the contents of the hint from the database, to use the Ajax stuff.

Copy CodeThe code is as follows:
<HTML>
<HEAD>
<title> text box with input matching </title>
<style>
Body,div {
Font-family:verdana;
line-height:100%;
font-size:10pt;

}
H1 {
Text-align:center;
Font-size:2.2em;
