校验输入金额、保留两位小数

<input type="text" class="word" v-model="form.price" @blur="handleInputBlur(form.price)" />


handleInputBlur() {
    var reg = /(^[1-9]\d*(\.\d{1,2})?$)|(^0(\.\d{1,2})?$)/;
    if (reg.test(this.form.price)) {
	} else {
	    uni.showToast({
	    title: '请输入正确价格',
	    icon: "none",
	    duration: 1000,
	})
	    this.form.price = ''
	    return false
	}
},
