The content of this article is about how to customize the showmodal pop-up box (with code) in the WeChat applet. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

I have been busy fixing bugs and adding new features recently. I haven’t summarized it for a long time, and I don’t know what to summarize. Let’s write a custom showmodal box first

No nonsense and go straight to the code

wxml part

<view class="mask" catchtouchmove="preventTouchMove" wx:if="{{showModal}}"></view>
<view class="modalDlg" wx:if="{{showModal}}">
<view class=&#39;img_wrap&#39;>
<image src=&#39;http://pbqyqto63.bkt.clouddn.com/%E9%92%BB%E7%9F%B3.png&#39;></image>
</view>
<view class=&#39;useralert_huiyuan&#39;>{{uservip}}</view>
<view class=&#39;useralert_quanyi&#39;>享受以下会员权益</view>
<view class=&#39;fenggexian&#39;></view>
<view class=&#39;vipinfo&#39;>{{vipinfo}}</view>
<view class=&#39;shutalert&#39; bindtap="go">

</view>
</view>

Among them, mask is the mask layer style

modalDlg is the pop-up container style

js part

Define a showModal in data[]: false The initial value must be false

I wrote two methods separately to control the switch because it is relatively rigid. , such

submit: function() {
this.setData({
showModal: true
})
},
go: function() {
this.setData({
showModal: false
})
},

Copy after login

There is a more direct

You can control the switch in one method, and it can also be used for the mask layer. Click on the mask layer to close

Here I am Feel free to write

and define a showalert in data: false

Method:

alert: function() {
var that= this;
this.setData({
showalert: !that.data.showalert
})
},

Copy after login
