How to implement text copy function in uniapp

When developing mobile applications, sometimes we need to implement text copy function so that users can easily copy a certain text to the clipboard so that it can be easily Paste and use elsewhere. In uniapp, this function can be achieved by using native APIs and plug-ins. This article will introduce how to implement the text copy function in uniapp, with code examples.

Step 1: Import the plug-in

In uniapp, you can use the "clipboard" plug-in in the uni plug-in market to realize the copy function. First, add the following configuration to the manifest.json of the project:

"mp-alipay": {
  "plugins": {
    "clipboard": {
      "version": "1.1.2",
      "provider": "bytedance"
    }
  }
}

Then, import the plug-in in the vue file of the page where the copy function needs to be used:

<-- 引入clipboard插件 -->
<import name="clipboard" src="@system.clipboard"></import>

Step 2: Call the copy function

Next, we can use the API provided by the plug-in to call the copy function in the code. The following is an example:

methods: {
  copyText() {
    uni.getSystemInfo({
      success: res => {
        if (res.platform == 'android') {
          uni.showToast({
            title: 'Android设备暂不支持复制功能',
            icon: 'none'
          });
        } else {
          uni.setClipboardData({
            data: '需要复制的文本',
            success: () => {
              uni.showToast({
                title: '复制成功'
              });
            },
            fail: () => {
              uni.showToast({
                title: '复制失败',
                icon: 'none'
              });
            }
          });
        }
      }
    });
  }
},

In the above code, we first use uni.getSystemInfo to obtain device information and determine whether the current running environment is an Android device. If it is an Android device, we will pop up a prompt Toast, because Android devices do not support the copy function yet. If the device is in another environment, we can use uni.setClipboardData to implement the copy function. After successful copying, we use uni.showToast to pop up a prompt.

Step 3: Call the trigger of the copy function

Finally, we need to add a button or other trigger event to the page to call the copy function. The following is a sample code that uses a button to trigger the copy function:

<button @click="copyText">复制文本</button>

In the above code, we call the copyText method in the click event of the button, which triggers the copy function.

Summary

Through the above steps, we can implement the text copy function in uniapp. First, import the clipboard plug-in, then call the copy function API in the code, and finally call the copy function through event triggering. This allows users to conveniently copy text to the clipboard, improving the user experience of the application. Hope this article is helpful to you!
