jquery自动完成插件(autocomplete)应用之PHP版
于工作中需要用到自动提示这个功能,呵呵,自己又是js小菜,于是百度了一下,找到一个用jquery与其插件autocomplete开发的.net版的自动完成功能,于是down下来了改成了php版的,并加了支持向上/向下选择文字等功能,放上来共享一下,纯体力活。。。 :)
1、下载jquery库,网址:http://jquery.com/ ;
2、下载jquery autocomplete插件或者直接使用我附件里提供的文件,自己下载下来的文件需要修改一些内容才能支持向上/向下选择文字、解决中文乱码,其中解决中文乱的问题网上有提到过,就是把文件中的encodeURI改成escape,还有把keydown修改成keyup即可,至于支持向上/向下选择文字请参看附件;
3、以下是调用代码:
auto.html内容:
