How to jump to application in uniapp

With the continuous development of mobile application development, developers' demand for multi-terminal applications is also gradually growing. In response to this situation, the uniapp platform came into being. uniapp is an application development framework that supports writing once and publishing on multiple terminals, so that developers do not have to repeatedly write applications for different platforms, thus improving development efficiency.

In uniapp, realizing cross-platform jump is also a necessary technology. This article focuses on the topic of uniapp jumping to applications, aiming to provide developers with some practical experience and skills.

1. The basic principle of uniapp jumping to the application

In uniapp, the basic principle of jumping to the application is implemented through JSBridge. JSBridge is a JS and Native interaction framework. It is a bridge between the front end and the client, providing the front end with the ability to call Native functions. In the uniapp platform, the method for JS to call native applications is uni.navigateToMiniProgram.

2. How to use uni.navigateToMiniProgram

uni.navigateToMiniProgram is an API provided by uniapp, which is used to jump to another mini program within the current mini program. Authorization will be performed during the process. If the user does not authorize, a pop-up window will prompt for authorization. The usage of this API is as follows:

uni.navigateToMiniProgram({
appId: '', // The appId of the mini program to jump to
path: '', // The appId to jump to Mini program page
extraData: {}, // Data passed to the target mini program, fill in if authorization is required
envVersion: '', // Used to specify the mini program version to jump to, if not specified The default is the official version
success(res) { //Callback when the jump is successful

console.log("跳转成功")

},
fail(res) { //Callback when the jump fails

console.log("跳转失败")

}
})

3. Example operation of jumping to the application

Next, we will demonstrate how to implement jumping to the application in uniapp based on an actual application scenario. operation.

Scenario: In the uniapp application, provide a button to jump to the WeChat video account application. Click to jump to the WeChat video account application.

Operation steps:

1. In the uniapp application, write a function that includes jumping to the WeChat video account.

function jumpToVideo() {
uni.navigateToMiniProgram({

appId: 'wx8f75c5ef5f5a5c02', //微信视频号应用的appId
path: '', //跳转到微信视频号的页面路径
success(res) {
  console.log("跳转成功")
},
fail(res) {
  console.log("跳转失败")
}

})
}

2. In the page of the uniapp application, add a button , and call the above function in the button's click event handler.

Jump to WeChat video account

3. In the WeChat applet developer background, configure jump to application parameters.

In the WeChat Mini Program Developer Backend, select "Settings" - "Third Party Settings" - "Associated Mini Program" in the menu bar, and set the parameters for jumping to the application: application ID, page path etc. content.

Through the above operations, you can jump to the WeChat video account application in the uniapp application.

Summary:

The uniapp framework provides a rich API and usage methods, and is a powerful tool for developing cross-platform applications. When implementing the function of jumping to an application, you need to pay attention to issues such as parameter setting and permission application. I hope this article can be helpful to developers.
