小程序提供的提示弹框没有错误,警告的样式只有success和loading的,但是在实际需求中需要很多的这样的提示框,简单的做了一个,供大家参考
效果预览:

代码介绍:
alert.js:
-
function alertShow(that, iconType, alertlable) {
-
that.setData({
-
isAlert: true,
-
iconType: iconType,
-
alertLable: alertlable
-
});
-
setTimeout(function (e) {
-
that.setData({
-
isAlert: false
-
})
-
}, 1500)
-
}
-
module.exports = {
-
alertShow: alertShow
-
}
alert.wxml
-
<view wx:if="{{isAlert}}" style="position:fixed;margin: auto;left: 0;right: 0;top: 0;bottom: 0;width: 70%;height: 22%;background-color: rgba(66, 66, 66, 0.9); text-align: center;border-radius: 10rpx;z-index:9999">
