Applet judges that the data is not empty

explain

The main thing is to simply use if(x), If x=0, It will be false, The judgment is empty , So we need to add another layer to judge whether it is 0, by 0 Is not empty .

Judge as not 0 js You can't use == and != , Use === and !==

One   Judgment of non object data

//  The judgment data of non object mode is not empty 
export const isDataNotEmpty = function(checkObj) {
	console.log(JSON.stringify(checkObj))
	let result = false
	if (checkObj === 0) {
		return true
	}
	// Checke if it is ""、 undefined、 null 、NaN、 []
	if (checkObj) {
		return true
	}
	return false
}

Two   Judgment of object data

//  Checklists 
verify() {
	let isCorrect = true
	let obj = this.dataForm
	let dataFormTitle = {
		spuName: ' Name of commodity ',
		price: ' Price ',
		barCode: ' Bar code of goods ',
		secondaryArea: ' Delivery area ',
		spuLabel: ' Product label ',
		saleType: ' Shipment type ',
		deliveryType: ' Delivery type ',
		payType: ' payment method ',
		storageStatus: ' state ',
		imagePath: ' Commodity images '
	}			
	for (var key in obj) {
		if (key !== 'barCode' && key !== 'imagePath') {
            //  This will set the value to 0 Also judged to be empty , Therefore, it is necessary to judge again as not 0
			if (!obj[key]) {
				if(obj[key] !== 0) {		
				    if(dataFormTitle[key]){
					    isCorrect = false
					    uni.showToast({
						    title: dataFormTitle[key] + ' It's empty ',
						    icon: 'none'
					    })
					    return isCorrect
				    }	
                }
			}
		}
	}
	return isCorrect
},
