我想從一個url中獲取JSON數據並存儲在sqlite中db.from sqlite數據庫我將數據轉換爲JSON數組對象並使用該值我tryinf執行if else條件我有沒有對象在JSON created_at和field3是要執行的數據，如果field3是0我不得不忽略，如果field3是1，我們必須計算日期n時差從該對象日期n時間下一個obj，其中field3以1結束。我的代碼如下。如果其他條件解析錯誤
function renderList1(tx,result){
newJson = [ ];
if (result != null && result.rows != null) {
for (var k = 0; k < result.rows.length; k++) {
var row = result.rows.item(k);
newJson[k] = { created_at:row.Created_at,entry_id:row.entry_id,field1:row.Field1,field2:row.Field2,field3:row.Field3 };
}
}
var jsonAll = JSON.stringify(newJson);
console.log(jsonAll);
var feeds = $.parseJSON(jsonAll);
console.log(feeds);
power();
function power(){
for (var i=0;i<feeds.length;i++) //feeds contain the JSON data
{
if(feeds[i]["field3"] === "1"){
//Start Time
var d1 = new Date(feeds[i]["created_at"]);
console.log(d1);
for (var j=i+1;j<feeds.length;j++) //compare objects starting from 'i' till next "1" is found
{
if(feeds[j]["field3"] === "0")
{
//End Time
var d2 = new Date(feeds[j]["created_at"]);
console.log(d2);
j=feeds.length;
}
}
//Time difference in milli seconds
var diff = d2.getTime() - d1.getTime();
var diffInHours= diff/1000diff/ 3600/1000;
console.log(diffInHours);
var pow = Powercon * diffInHours;
console.log(pow);
}else{
console.log("Field3 is 0");
}
}
}

我想上面的代碼，當我運行我的，如果和其他條件，如果場3等於1了一個問題，如果條件，但它要它應該執行其他條件。任何人都可以幫助我哪裏出錯？謝謝
你嘗試過嗎？（feeds [i] [「field3」] === 1）{？可能是它的整數。 – abhiklpm
@Anusha嘗試'如果（飼料[我] [「field3」] ==「1」）' – user3441151
