I am working on a WeChat applet recently and need to implement a graph style of process progress. Below I have brought you the example code of the graph style function of the WeChat applet to implement process progress. Friends who need it can refer to it

I am currently working on a WeChat applet, and I need to implement a process progress diagram as shown below

Requirements:

1. Not completed Gray dots represent

2. Complete settings are represented by blue dots

3. The current status is represented by small dots with an outer ring

It is relatively simple to implement. The implementation idea is to use a list. The style of each item in the list is as shown below

Use The drawings in win10 drawing board are not good-looking

What the picture means is that there is a line in front of each item, a circle in the middle, and a line behind it. The reason for this is that the text below needs to be centered below the circle. If no text is needed, it would be simpler to have a circle followed by a straight line.

According to the above picture, the html layout is as follows

 <view class=&#39;order_process&#39;>
  <view class=&#39;process_wrap&#39; wx:for="{{processData}}" wx:key="">
  <view class=&#39;process&#39;>
   <view class=&#39;process_line&#39; style="background:{{item.start}}"></view>
   <image class=&#39;process_icon&#39; src="{{item.icon}}"></image>
   <view class=&#39;process_line&#39; style="background:{{item.end}}"></view>
  </view>
  <text class=&#39;process_name&#39;>{{item.name}}</text>
  </view>
 </view>

OK The list definitely needs an array. The array is as follows

processData: [{
  name: '提交工單',
  start: '#fff',
  end: '#EFF3F6',
  icon: '../../img/process_1.png'
 },
 {
  name: '已接單',
  start: '#EFF3F6',
  end: '#EFF3F6',
  icon: '../../img/process_1.png'
 },
 {
  name: '開始維修',
  start: '#EFF3F6',
  end: '#EFF3F6',
  icon: '../../img/process_1.png'
 },
 {
  name: '維修結(jié)束',
  start: '#EFF3F6',
  end: '#EFF3F6',
  icon: '../../img/process_1.png'
 },
 {
  name: '已確認(rèn)',
  start: '#EFF3F6',
  end: '#fff',
  icon: '../../img/process_1.png'
 }],
 },

According to the above item picture we will see direct display If there will be an extra line on both sides, how can I remove these two lines? It is very simple. Just make the background color of the parent container the same as the previous color.

Change the background of the parent layout to white, then control the color of the front line segment in the first item in the list to white, and the color of the back line segment in the last item to white. This way it looks like the line segments on both sides have been removed

When the data changes, we only need to change the properties of the objects in the array. It is better to use the following as a reference

//進(jìn)度條的狀態(tài)
 setPeocessIcon: function () {
 var index = 0//記錄狀態(tài)為1的最后的位置
 var processArr = this.data.processData
 // console.log("progress", this.data.detailData.progress)
 for (var i = 0; i < this.data.detailData.progress.length; i++) {
  var item = this.data.detailData.progress[i]
  processArr[i].name = item.word
  if (item.state == 1) {
  index = i
  processArr[i].icon = "../../img/process_3.png"
  processArr[i].start = "#45B2FE"
  processArr[i].end = "#45B2FE"
  } else {
  processArr[i].icon = "../../img/process_1.png"
  processArr[i].start = "#EFF3F6"
  processArr[i].end = "#EFF3F6"
  }
 }
 processArr[index].icon = "../../img/process_2.png"
 processArr[index].end = "#EFF3F6"
 processArr[0].start = "#fff"
 processArr[this.data.detailData.progress.length - 1].end = "#fff"
 this.setData({
  processData: processArr
 })
 },

In the data of the above code, state is used to represent completion and incompleteness. We set the completed ones to blue and the unfinished ones to gray.

Use index to record whether it is the current point (the current point is the last one completed by state).

The code in the final css is also very simple

.order_process {
 display: flex;
 flex-wrap: nowrap;
 padding: 10rpx 10rpx 20rpx 10rpx;
 background-color: #fff;
}

.process_wrap {
 display: flex;
 flex-direction: column;
 flex: 1;
 align-items: center;
}

.process {
 display: flex;
 align-items: center;
 width: 100%;
}

.process_icon {
 width: 50rpx;
 height: 50rpx;
}

.process_line {
 background: #eff3f6;
 flex: 1;
 height: 5rpx;
}

.process_name {
 font-size: 24rpx;
}

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
