本文介绍了select和sugget结合起来使用的例子,支持下拉的直接选择,也支持在下拉内容中输入过滤。
整体效果就是下面这样的:

javascript实现下拉提示选择框 

1、首先需要引入如下文件

<link href="select2.min.css" rel="stylesheet" /> 
<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-2.1.4.min.js">

这里要注意jquery要放在select2的前面。
2、一些实例

<!DOCTYPE html> 
<html lang="en"> 
 
<head> 
  <meta charset="UTF-8"> 
  <title>Document</title> 
  <link href="select2.min.css" rel="stylesheet" /> 
  <style type="text/css"> 
  .select2-dropdown { 
    margin-left: 8px !important; 
    margin-top: 20px !important; 
  } 
  </style> 
</head>

P70系列延期,华为新旗舰将在下月发布

3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。

而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?

根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
