[#1]

var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates"]

var uniquValues = unique(indexArray);

alert(uniquValues);

function unique(array) {
var o = {};
r = [];
for (i = 0; i < array.length; i++) {
o[array[i]] = array[i];
}
for (i in o) {
r.push(o[i]);
}
return r;
};

Try the following

var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates"]

var uniquValues = unique(indexArray);

alert(uniquValues);

function unique(array) {
	var o = {};
	r = [];
	for (i = 0; i < array.length; i++) {
		if(o[array[i]])
			delete o[array[i]]
		else
			o[array[i]] = array[i];
	}
	for (i in o) {
		r.push(o[i]);
	}
	return r;
};

Hi Manan,

Superrrrrrr.

But,

Try this index value:
var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates","Apple"];

The index value must be removed, its available n numbers are OK but must be removed.

Thanks

I completely lost it, please explain again. I checked with the new value that you sent and the returned array has values Cherry, Dates, Apple which looks correct. What is the issue?

Hi Manan,

The Duplicate values need to remove, 

Output of your lines is: Cherry, Dates, Apple

but expected output is: Cherry, Dates

apple is duplicate value and beed to remove it come 2 or and above.

Thanks

Try the following

var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates"]

var uniquValues = unique(indexArray);

alert(uniquValues);

function unique(array) {
	var o = {};
	r = [];
	var d = []
	for (i = 0; i < array.length; i++) {
		if(o[array[i]])
		{
			d.push(o[array[i]])
			delete (o[array[i]])
		}
		else if(!d[array[i]])
			o[array[i]] = array[i];
	}
	for (i in o) {
		r.push(o[i]);
	}
	return r;
};

Works for me just fine, see the screengrab of the same code executing on my machine

Hi Manam,

Please use the following index value:

var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates","Apple","Banana","Graphes"]

Apple, Banana are repeated values. so need to remove those in the array

required output: Cherry, Dates and Graphes

Glad for your response every time.

Thanks

Apologies, the variable d should have been an object, but I wrote it as an array. Try the following, it should work fine now hopefully. This code can be made more concise and more understandable, I am hopeful you would do that once it works for your use cases.

var indexArray =["Apple", "Banana","Cherry","Apple","Banana","Dates","Apple","Banana","Graphes"]
//var indexArray = ["Apple", "Banana","Cherry","Apple","Banana","Dates"]

var uniquValues = unique(indexArray);

alert(uniquValues);

function unique(array) {
	var o = {};
	r = [];
	var d = {}
	for (i = 0; i < array.length; i++) {
		if(o[array[i]])
		{
			d[o[array[i]]] = 1
			delete (o[array[i]])
		}
		else if(!d[array[i]])
			o[array[i]] = array[i];
	}
	for (i in o) {
		r.push(o[i]);
	}
	return r;
};
