URLからJSONデータを取得してsqlite db.From sqlite dbに格納しようとしています。データをJSON配列のオブジェクトに変換していて、その値を使用しています。それ以外の場合は、JSON created_atにはn個のオブジェクトがありません.field3は、field3が0の場合に実行されるデータです。無視する必要があります。また、field3が1の場合は、次のobjは、field3の1.Myコードの終わりです。else条件の解析でエラーが発生しました
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");
}
}
}
JSONデータ：私は条件がなく、それが起こっている場合、それは実行する必要があり、私はフィールド3が1に等しい場合ならば、他の条件で問題を抱えて実行したときに、私は上記のコードを試みた
