微信小程序这个坑啊,js动态修改样式,我们并不能用js或者jq 轻轻松松一行代码搞定。或者用removeClass addClass 来修改样式。

以下是一种动态修改样式的方法,原理是绑定数据,然后动态的修改数据,从而实现动态样式的改变而已。感觉有点········那个啥的,怪怪的。不过也没办法了。如果你有更好的方法,可以在评论区分享一下。

test.wxml

<view style="text-align: center;">
 <label style="color:pw_color;">我会变色</label>
 <button bindtap="clickRed">变红</button>
 <button bindtap="clickgreen">变绿</button>
</view>

test.js

Page({
 data: {
 color: "red"
 },
 clickRed: function () {
 this.setData({
  color: "red"
 })
 },
 clickgreen: function () {
 this.setData({
  color: "green"
 })
 }
})

效果
