				<view class="yanzhengma" @click="get_code">{{time}} {{text}}</view>
			</view>
		</view>

		<view class="mylogin" @click="submitFun">确定</view>
	</view>

</template>

<script>
	export default {
		data() {
			return {
				//验证码登录
				mobile: '', //手机号码
				vxcode: '', //验证码

				// 验证码（主要代码，直接复制使用即可）
				time: '',
				text: '获取验证码',
			}
		},
		onLoad(e) {},
		onShow() {},

		methods: { 
			//获取验证码（主要代码，直接复制使用即可）
			async get_code() {
				var that = this;
				if (!that.mobile) {
					uni.showToast({
						title: '请输入手机号',
						icon: 'none'
					})
					return;
				}
				var data = {
					mobile: that.mobile,
				}
				this.$api.appPlateForm('post', this.$url.url.auth_vscode, data, (res) => {
					if (res.code == 200) {
						that.disabled = true;
						that.setInterValFunc();

					}
				});
			},
			setInterValFunc() {
				this.time = 60;
				this.text = '秒';
				this.setTime = setInterval(() => {
					if (this.time - 1 == 0) {
						this.time = '';
						this.text = '重新获取';
						this.code = '';
						this.disabled = false;
						clearInterval(this.setTime);
					} else {
						this.time--;
					}
				}, 1000);
			},

			// 确定
			submitFun() {
				var that = this;
				if (!that.mobile) {
					uni.showToast({
						title: '请输入手机号',
						icon: 'none'
					})
					return;
				}
				
				if (!that.vxcode) {
					uni.showToast({
						title: '请输入验证码',
						icon: 'none'
					})
					return;
				}
				
				//调用列表方法
				var data = {
					mobile: that.mobile, //手机号
					code:that.vxcode,//验证码
				}
				this.$api.appPlateForm('post', this.$url.url.auth_forget_password, data, (res) => {
					if (res.code == 200) {
						uni.showToast({
							icon: 'none',
							title: res.msg
						})
						setTimeout(() => {
							uni.navigateBack()
						}, 1000)
					}
				});
			},
		}
	}
</script>
