我正在尝试存储来自json文件存储服务器端的数据,我正在使用角度js和html,我可以通过在我的indexeddb函数中输入它来添加json数据,但是我需要使用http.get和然后把它放在数据库中,这是我的代码。
$scope.save_data = function save_data(event) {
let indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;
let open = indexedDB.open("myDB", 1);
open.onupgradeneeded = function () {
let db = open.result;
let store = db.createObjectStore("the_Times", { keyPath: "id", value: "Article1" });
let store1 = db.createObjectStore("the_Times1", { keyPath: "id1", value: "Article2" });
let store2 = db.createObjectStore("the_Times2", { keyPath: "id2", value: "Article3" });
let index = store.createIndex("Article1", ["news.Article1"]);
let index1 = store1.createIndex("Article2", ["news.Article2"]);
let index2 = store2.createIndex("Article3", ["news.Article3"]);
open.onsuccess = function (e) {
let db = open.result;
let tx = db.transaction("the_Times", "readwrite");
let tx1 = db.transaction("the_Times1", "readwrite");
let tx2 = db.transaction("the_Times2", "readwrite");
let store = tx.objectStore("the_Times");
let store1 = tx1.objectStore("the_Times1");
let store2 = tx2.objectStore("the_Times2");
let index = store.index("Article1");
let index1 = store1.index("Article2");
let index2 = store2.index("Article3");
console.log('added successfully');
//this is where i want to pull data from a url containing the json data and put it in the DB
store.put({"JSON string is here... Should be url json data"});
store1.put({"JSON string is here"});
store2.put({"JSON string is here"});
let transaction = db.transaction(["the_Times"], "readonly");
let objectStore = transaction.objectStore("the_Times", "the_Times1", "the_Times2");
let cursor = objectStore.openCursor();
cursor.onsuccess = function (e) {
let res = e.target.result;
if (res) {
console.log(res.key);
console.dir(res.value);
res.continue();
}
tx.oncomplete = function () {
db.open();
};
}
}
}
};
