This article will lead everyone to implement the clipboard function of the mini program

”

Preface

In the past two days, I have been implementing a function to copy a connection from WeChat. When the mini program is opened, the content can be directly detected and pasted.

Implement function

• Detect content copied by WeChat.
• Regularly matches the required content.

1. Mini program to implement clipboard function

The effect is as follows

Open the WeChat document and you can see the two interfaces provided, one is to set the contents of the system clipboard, and the other is to obtain the system clipboard Content

So what this article will introduce to you is to obtain the contents of the system clipboard, the interface iswx. getClipboardData

First familiarize yourself with the usage rules of this interface according to the documentation.

The above are the rules for using the clipboard, and the usage methods are also provided in the document. Once you know these contents You can come to your own project for verification.

The process here is just to give some development experience to partners who are new to small programs.

<span style="display: block; background: url(https://files.mdnice.com/point.png); height: 30px; width: 100%; background-size: 40px; background-repeat: no-repeat; background-color: #282c34; margin-bottom: -7px; border-radius: 5px; background-position: 10px 10px;"></span><code class="hljs" style="overflow-x: auto; padding: 16px; color: #abb2bf; display: -webkit-box; font-family: Operator Mono, Consolas, Monaco, Menlo, monospace; font-size: 12px; -webkit-overflow-scrolling: touch; padding-top: 15px; background: #282c34; border-radius: 5px;">wx.getClipboardData({<br/>  success (res){<br/>    console.log(res.data)<br/>  }<br/>})<br/></code>

2. Code implementation

The picture below is a very simple implementation, you can see the copied data is printed directly on the console.

Then the next thing to do is to regular match the copied content to match the content we only need.

The following js code can create a new file in the utils directory.

<span style="display: block; background: url(https://files.mdnice.com/point.png); height: 30px; width: 100%; background-size: 40px; background-repeat: no-repeat; background-color: #282c34; margin-bottom: -7px; border-radius: 5px; background-position: 10px 10px;"></span><code class="hljs" style="overflow-x: auto; padding: 16px; color: #abb2bf; display: -webkit-box; font-family: Operator Mono, Consolas, Monaco, Menlo, monospace; font-size: 12px; -webkit-overflow-scrolling: touch; padding-top: 15px; background: #282c34; border-radius: 5px;"><span class="hljs-keyword" style="color: #c678dd; line-height: 26px;">var</span> t = {};<br/><br/>t.handleUrl = <span class="hljs-function" style="line-height: 26px;"><span class="hljs-keyword" style="color: #c678dd; line-height: 26px;">function</span>(<span class="hljs-params" style="line-height: 26px;">t</span>) </span>{<br/>    <span class="hljs-keyword" style="color: #c678dd; line-height: 26px;">var</span> e = <span class="hljs-regexp" style="color: #98c379; line-height: 26px;">/(http:\/\/|https:\/\/)((\w|=|\?|\.|\/|&|-)+)/g</span>;<br/>    <span class="hljs-keyword" style="color: #c678dd; line-height: 26px;">return</span> !!(t = t.match(e)) && t[<span class="hljs-number" style="color: #d19a66; line-height: 26px;">0</span>];<br/>}, <span class="hljs-built_in" style="color: #e6c07b; line-height: 26px;">module</span>.exports = t;<br/></code>

Then import the file where you need to import it and you can use it.

Call the data required for regular matching, and the returned value is the result of the matching.

The second step is to no longer pop up the box when the content of the clipboard is detected to be consistent with the set value.

弹框的代码就是showModel这个接口，可以自行查看文档哈！
