我在cloud firestor中創(chuàng)建了一個(gè)數(shù)據(jù)庫，所以現(xiàn)在我想通過輸入字段向其中添加一些信息，當(dāng)輸入字段為空信息時(shí)存儲(chǔ)問題并且catch函數(shù)不起作用，我該如何修復(fù)它，并進(jìn)行catch功能工作。這是代碼：HTML：<div class="container"> <input type="text" placeholder="Enter the country" id="country-field" required> <p class="selectPar">Enter City</p> <input type="text" placeholder="Enter the city" id="city-field" required> <p class="selectPar">Enter the place name</p> <input type="text" placeholder="Enter the place name" id="placename-field" required> <p class="selectPar">Enter Address</p> <input type="text" placeholder="Enter the address" id="address-field" required> </div> </div> <div id="btnFrmAlignSec"> <button id="btnFrm" type="button" onclick="AddToDataBase()">Send to admin</button> </div>JavaScript函數(shù)添加到數(shù)據(jù)庫（）{ var inputCountry = document.getElementById("country-field").value; var inputCity = document.getElementById("city-field").value; var inputAddress = document.getElementById("address-field").value; var inputNameofPlace = document.getElementById("placename-field").value; // Add a new document in collection "cities" db.collection("UsersShare").doc().set({ name:inputNameofPlace, city:inputCity, country:inputCountry, address:inputAddress, }) .then(function() { console.log("Document successfully written!"); document.getElementById("reply").style.display="inline"; }) .catch(function(error) { console.error("Error writing document: ", error); });}

if(inputCountry.trim() && inputCity.trim() && inputAddress.trim() &&
inputNameOfPlace.trim()){
// Add a new document in collection
// your code
} else {
// fields are empty --- error message
}

您可以事先檢查字段是否為空，如果不是，則對數(shù)據(jù)庫進(jìn)行操作，否則將錯(cuò)誤記錄到控制臺(tái)，就像您的 catch 函數(shù)一樣：
if(inputCountry && inputCity && inputAddress && inputNameOfPlace){
db.coll.....
} else {
console.error('Field(s) are empty');
}
