I am using a multiselect element from select2 to enter multiple "tags". When I want to get the value from the element I get something like this (for tag1 en tag2 which I entered in the box):
[{"id":"tag1","text":"tag1"},{"id":"tag2","text":"tag2"}]
How do I get the result from text in an array something like this:
[0] = "tag1"
[1] = "tag2"
And how do I reverse this process?
Here's another approach
[{"id":"tag1","text":"tag1"},{"id":"tag2","text":"tag2"}].map(function(el) {
return el.id;
});
map(), nice approach which returns those id to an array.
Try this simple iteration.
var obj = [{"id":"tag1","text":"tag1"},{"id":"tag2","text":"tag2"}] ;
for (var i =0; i< obj.length ;i++) {
console.log(obj[i].id);
}
var data = JSON.parse('[{"id":"tag1","text":"tag1"},{"id":"tag2","text":"tag2"}] ');
data[0].id
data[1].id
Try this will help you
