To retrieve all the records from IndexedDB that are not equal to a specific value, you can use the openCursor()
method to iterate over each record in the object store, and then use a conditional statement to filter out the records that do match the desired value.
Here's an example code snippet that demonstrates this approach:
var transaction = db.transaction(["objectStoreName"], "readonly");
var objectStore = transaction.objectStore("objectStoreName");
var results = [];
objectStore.openCursor().onsuccess = function(event) {
var cursor = event.target.result;
if (cursor) {
if (cursor.value.fieldName !== "specificValue") {
results.push(cursor.value);
}
cursor.continue();
}
};
transaction.oncomplete = function(event) {
console.log("Retrieved records:", results);
};
In this example, we first create a read-only transaction on the desired object store, and then define an empty results
array to store the filtered records. We then use the openCursor()
method to iterate over each record in the object store, and check if the value of the fieldName
property is not equal to the specified value ("specificValue" in this case). If the record does not match the desired value, we push it into the results
array. Finally, when the iteration is complete, we log the resulting results
array to the console.
