微信小程序自定義switch

微信小程序自帶的switch，可以改變大小，顏色，但是是有侷限性的，所以好多時候都需要自己去寫一個。

修改微信小程序自帶對的switch

/*swtich整體大小及背景色*/
.wx-switch-input{
    width:82rpx !important;
    height:36rpx !important;
    background: red !important;
    border: red !important;
}
/*關閉狀態的樣式*/
.wx-switch-input::before{
    width:80rpx !important;
    height: 36rpx !important;
}
/*開啓狀態的樣式*/
.wx-switch-input::after{
    width: 40rpx !important;
    height: 36rpx !important;
}

自定義switch

<view class="switch {{isOpen? 'toggle-on' : 'toggle-off'}}" style="background-color:{{anonymousSwitch ?'#00CED0' : '#ddd'}}" bindtap="selSwitch"></view>

---

Page({
	data:{
		isOpen:false,//默認關閉
	},
	onLoad:function(){
	
	},
	selSwitch(){
		this.data.isOpen=!this.data.isOpen;
		this.setData({
			isOpen:this.data.isOpen;
		})
	}
})
