What this article recommends is to use angularjs to implement the entire process of integrating WeChat’s newly launched UI (weui). Friends who have the same needs can refer to the following

Introduction

Not long ago, WeChat launched its own set of UI. I see that many developers have applied it to some front-end frameworks, such as react and vue. . Recently I am learning Angularjs, so I also want to integrate this UI into this framework. I have tried it in the past few days and simply applied a function. Now I will share it with you. If the separation is not done well, please give some advice from an expert.

Suitable for readers

who have a certain foundation of Angularjs and understand ngRoute and ngAnimate.

Includes files

When integrating, refer to the official demo page and made a demo page myself, completely using Angularjs Made without referencing other frameworks. Let's first explain the imported files.

Use angular.min.js 1.4.9
Use angular-route.min.js 1.4.9
Use angular-animate.min.js 1.4.9
Use weui.min.css 0.4.0

At first, I wanted to make a single page like the official demo page. After development, I found that putting all the content into one file was too messy. Therefore, I used the routing function of Angularjs to separate each small function into separate pages. Load in when needed. This is achieved using the template loading function. Therefore, the navigation page code is displayed very cleanly. If you want to use which part of the function code, you can directly use the corresponding html page and js script file, which is convenient and fast.

The following is the code for the navigation page:

<!DOCTYPE html>
<html lang="en" ng-app="weuiapp">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=0">
  <title>WeUI</title>
  <link rel="stylesheet" href="./css/weui.css" />
</head>
<style type="text/css">
.home,
.view {
  position: absolute;
  width: 100%;
  left: 0;
  top: 0;
}

Most of the above codes come from the official homepage code. Since Angularjs is used, corresponding attributes are added, including ngApp, ngController, ngClick, ngIf and ngView that displays the function demonstration page.

In the code, the showBlock function is used in ngClick. The parameter is the function string of the current click. The parameters of this function are not used after using the routing function. Only the hidden and displayed navigation is added to this function. part and function demonstration part of the code, please see the script code below for details.

This section is the functional code to be implemented by the function. It controls the variables homeShow and viewShow respectively to implement navigation and function demonstration. Showing and hiding the two parts.

.animation(&#39;.home&#39;, [&#39;$animateCss&#39;, function($animateCss) {

The above is the animation effect code when the navigation part is displayed. The navigation part is initialized to absolute positioning, so that it moves out of the display area to the left and fades out before disappearing. After viewing the function demonstration and returning to the navigation, the animation is reversed. The $animateCss service of ngAnimate is used here, and the entry event enter and the exit event leave provided by this service are used. Other animation functions are the same.

$routeProvider
  .when(&#39;/&#39;, {
    controller: &#39;home&#39;,

This is a routing service, corresponding to the href attribute of the a tag in html, so the showBlock function is not used in this program The parameters are no longer useful. This function was only created to add dynamic effects.

Next, let’s take a look at the page code of the function demonstration part.

This is the demo page code for loading the waiting prompt function. There are two styles in total. One is to display text; Second, there is a loading waiting animation and prompt text is displayed.

There are two buttons on the page. Their function is to exhale these two styles respectively. After each style is exhaled, it will automatically disappear after 3 seconds.

In the js of the navigation page, there is a controller and an animation function that call the functions in the script code of this function page, namely the controller function toast() and the animation function toastAnimate(). The code of the script file is as follows.

//toast控制器
function toast($scope, $interval) {
  $scope.toastHide = 0;
  $scope.loadingToastHide = 0;

  $scope.showToast = function() {
    $scope.toastHide = 1;

    $interval(function() {
      $scope.toastHide = 0;
    }, 3000, 1);
  }

  $scope.showLoadingToast = function() {
    $scope.loadingToastHide = 1;

    $interval(function() {
      $scope.loadingToastHide = 0;
    }, 3000, 1);
  }
}

//显示与隐藏时的动画，使用ngAnimate中的$animateCss服务
function toastAnimate($animateCss) {
  return {
    enter: function(element, doneFn) {
      return $animateCss(element, {
        from: { opacity: 0 },
        to: { opacity: 1 },
        duration: .3
      });
    },
    leave: function(element, doneFn) {
      return $animateCss(element, {
        from: { opacity: 1 },
        to: { opacity: 0 },
        duration: .3
      });
    }
  }

At this point, navigation and a function demonstration page have been implemented. Since most of the UI is static and not dynamic, you only need to copy the official demo. If it is necessary to add dynamic code, we have only done this one now, and will continue to add it to completion in the future.
