el-input及uniappinput限制输入并提示

用if判断小于0的直接设为0

通过正则限制只能输入数字或小数点

uniapp

checkPrice(e) {
				let that = this;
				let num = e.detail.value
				if (num > 10000) {
					this.indata.count = 10000;
					uni.showToast({
						title: '最大可兑换10000',
						icon: 'none',
						duration: 1500
					});
				} else if (num < 0) {
					this.indata.count = 0;
					uni.showToast({
						title: '请输入正确的数量',
						icon: 'none',
						duration: 1500
					});
				}
			},
