在方法中，分支不要嵌套

```
login(){
	if(!this.hasRead){
		uni.showModal({
			title: '提示',
			content: '请勾选用户协议',
			showCancel: false,
		});
	}else{
		if(this.phone == '' || !this.phone){
			uni.showModal({
				title: '提示',
				content: '请填写手机号码',
				showCancel: false,
			});
		}else{
			if(this.loginType == 0 && (this.code == '' || !this.code)){
				uni.showModal({
					title: '提示',
					content: '请填写验证码',
					showCancel: false,
				});
			}else{
				if(this.loginType == 1 && (this.password == '' || !this.password)){
					uni.showModal({
						title: '提示',
						content: '请输入密码',
						showCancel: false,
					});
				}else{
					var that = this;
					console.log('openid',that.openid);
					uni.request({
						url: config.apiHost + config.apiUrl.sendLoginData,
						data: {phone: that.phone, type: 'code', code: that.code, openId: that.openid, loginType: that.loginType, password: that.password}	,
						success: function (res) {
							let response = res.data;
							if(response.code == 0){
								uni.setStorageSync('adminId', response.data.id);
								uni.setStorageSync('schoolId', response.data.schoolId);
								let redirect = uni.getStorageSync('redirectUrl');
								if(!response.data.mp_open_id || response.data.mp_open_id == ''){
									//跳转新的webview页面获取用户公众号的openid
									uni.navigateTo({
										url: '/pages/index/open?userId='+ response.data.id
									})
									return;
								}
								// uni.setStorageSync('adminTypes', response.data.types);
								uni.showToast({
									title: '登录成功，即将跳转首页',
									duration: 2000
								});
								if(redirect){
									uni.reLaunch({
										url: redirect
									});
								}else{
									uni.reLaunch({
										url: '/pages/index/index'
									});
								}
							}else{
								uni.showModal({

									content: response.msg,

					});
				}
			}

	}
},
```

修改后

```
