I am trying to use indexedDB to store some data client side and I am having trouble properly setting up the database.
I am following the tutorial here
The onupgradeneeded()
event is being fired when I install the extension for the first time, but for some reason, none of the events associated with the object store transaction are being fired and I can't find any documentation that addresses this issue.
This is the relevant code:
const db_name="Tags";
var request = window.indexedDB.open(db_name, 1);
var tags = [
//codes: 0 - markdown wrap tag
// 1 - HTML wrap tag
// 2 - single tag
{ domain: "www.youtube.com",
bold:["*",0],
strikethrough:["-",0],
italic:["_",0]
},
{ domain: "www.stackoverflow.com",
bold:["<strong>",1],
italic:["<em>",1],
strikethrough:["<del>",1],
superscript:["<sup>",1],
subscript:["<sub>",1],
heading1:["<h1>",1],
heading2:["<h2>",1],
heading3:["<h3>",1],
blockquote:["<blockquote>",1],
code:["<code>",1],
newline:["<br>",2],
horizontal:["<hr>",2]
}
];
request.onerror = function(event) {
alert("Error opening the database");
};
request.onupgradeneeded = function(event) {
var db = event.target.result;
var objectStore = db.createObjectStore("domains", {keyPath: "domain" });
objectStore.createIndex("domain", "domain", { unique: true });
alert("I'm trying to do stuff");
objectStore.transaction.oncomplete = function(event) {
var domanStore=db.transaction("domains","readwrite").objectStore("domains");
for(var i in tags)
{
domainStore.add(tags[i]);
alert("added " + tags[i]["domain"] + " to the DB");
}
alert("I might have done stuff");
};
objectStore.transaction.onerror = function(event) {
alert("Transaction error");
};
objectStore.transaction.onabort = function(event){
alert("Transaction aborted");
};
db.onerror=function(event){
alert("DB ERROR bubbled up");
};
alert("I thought I did something");
};
The only alert boxes that pop up are for
I'm trying to do stuff.
and
I thought I did something.
The console shows no errors.
The only thing I can think of is that I'm not creating the object store correctly, but I can't see what I'm doing wrong here.
Some other helpful sources:
You can use something like this-
const db_name="Tags";
var request = window.indexedDB.open(db_name, 1);
var tags = [
//codes: 0 - markdown wrap tag
// 1 - HTML wrap tag
// 2 - single tag
{ domain: "www.youtube.com",
bold:["*",0],
strikethrough:["-",0],
italic:["_",0]
},
{ domain: "www.stackoverflow.com",
bold:["<strong>",1],
italic:["<em>",1],
strikethrough:["<del>",1],
superscript:["<sup>",1],
subscript:["<sub>",1],
heading1:["<h1>",1],
heading2:["<h2>",1],
heading3:["<h3>",1],
blockquote:["<blockquote>",1],
code:["<code>",1],
newline:["<br>",2],
horizontal:["<hr>",2]
}
];
request.onerror = function(event) {
alert("Error opening the database");
};
request.onupgradeneeded = function(event)
{
var db = event.target.result;
var objectStore = db.createObjectStore("domains", {keyPath: "domain" });
objectStore.createIndex("domain", "domain", { unique: true });
alert("I'm trying to do stuff");
for(var i in tags)
{
objectStore.add(tags[i]);
alert("added " + tags[i]["domain"] + " to the DB");
}
alert("I might have done stuff");
alert("I thought I did something");
};
Since you are populating the data at time of creation of the objectStore you don't have to create a transaction in onupgradeneeded function, outside of this function you have to create transaction
