Merge keys array and values array into an object in JavaScript
(14 answers)
Closed 8 years ago.
I have 2 arrays which are the same length like this:
$scope.access_name = ['group1','group2','group3','group4']
access_value=[1,2,1,3]
How can I combine to have result like this:
object_access = {'group1:1','group2:2','group3:1','group4:3'}
thankyou very much
var object_access={};
for(int i=0;i<access_value.length;i++)
{
object_access[$scope.access_name[i]]=access_value[i];
}

How to access Viena
There could be a lot of cities
[{"Viena":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"},{..},{..}],{"Paris":[{..}]} ]
You can use Array.filter for this.
var data = [{"Viena":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"}]},{"Paris":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"}]}];
var result = data.filter(function(value){return Object.keys(value).indexOf("Viena") != -1;});
console.log(result[0]);

Here is my jsfiddle
Here is my array looks like
var arr = [];
arr['alpha'] = {'a':'1','b':'1'};
arr['beta'] = {'a':'2','b':'4'};
console.log(arr)
When i take console.log(arr.length) It says 0. So i can't able to for loop this one
How can i iterate this array ?

I don't want to use jquery, i prefer only javascript

I dont see how we can find the length of an object. For arrays i can your array.length but it doesnt work for objects, any suggestions?
Thanks!
Just like that:
Object.keys(objectName).length;
