The output I am receiving is:
[{"ref":"contact.html","score":0.7071067811865475}] $.getJSON( "index.json", function(data) {
idx = lunr.Index.load(data);
var searchResults = idx.search(variabletosearch);
var formattedResults = JSON.stringify(searchResults);
console.log(formattedResults);
});
How can I extract the value of 'ref'? When I attempt
console.log(formattedResults[0].ref);UPDATE:
Just a reminder that JSON.stringify returns a string, not an object. Therefore, in this scenario, 'final' holds a string that mirrors the data from the 'results' object.
To retrieve data from an object, you can utilize result[0].ref. Alternatively, if you prefer to use 'final' (even though it's not necessary), you can perform the following:
final = JSON.parse(final)
console.log(final[0].ref)
If there is a single object in the array, the previous solutions suffice. However, since arrays are designed to accommodate multiple objects, consider the following approach:
var arr = [
{"ref": "object1", "score": "1"},
{"ref": "object2", "score": "2"}
]
arr.map(function(object) {
console.log(object.ref)
})
JSFiddle showcasing the use of an alert instead of console.log()
You can also opt for a loop, although the map function provides a neater solution.
const data = [{"page":"home.html","rating":0.7071067811865475}];
data[0].page;
data[0] refers to the first element in the array, which is the object
{"page":"home.html","rating":0.7071067811865475}Here is an expanded version:
const data = [{"page":"home.html","rating":0.7071067811865475}];
const myItem = data[0];
console.log(myItem.page);
// you could also include null checks
if (myItem) {
console.log(myItem.page ? myItem.page : 'no entry');
}
Let's say
let example = [{"location":"page.html","value":0.7071067811865475}];
therefore:
let location = example[0].location;
