I am working in jQueryMobile and PhoneGap.

I Have 2 objects: eup and gld. The length of eup is 22, and the length of gld is 6.

I have tried:

//common.push(eup,gld);
//common.join(eup,gld);
//common.concat(eup,gld);

alert(common.length)  // 2

When I check common.length, it's 2.

But for my logic I need it as 1. That means merge eup and gld and shows its length as 1. I got the result of eup and gld from two different APIs and it's in JSON format. The main thing is the tags of both objects are identical. So I think it should be possible to merge these values as one and show its length as ONE.

Is there any solution for this????

  • Which is the structure of those arrays? Commented May 31, 2013 at 9:23
  • why 1? length of final array should be 28 , right ? Commented May 31, 2013 at 9:26
  • Like this { "company_data": { "doors": "2-4 Doors", "transmission": "Manual", "aircondition": "A/C", "CarSize": "xxxx", "type": "ss", "total_price": "1124.16" } } Commented May 31, 2013 at 9:29
  • are you trying to merge two objects or arrays ? Commented May 31, 2013 at 9:31
  • @tracevipin I need this : common.length = 1 but now I got common.length = 2 (eup,gld) Commented May 31, 2013 at 9:31

It sounds like you want to extend an object, not concatenate an array.

var common = $.extend({}, eup, gld);

However, this will overwrite values with common keys. To merge without overwriting, the solution is explained at Merge JS objects without overwriting.

@Derek : Actually my requirement is; In my application; I have two or more api’s . In its response as JSON format; there are lot of Tags are given in the Result but my required details are given in a Tag known as "company_data". so now I’m collecting company_data details to an array in each respond file.. var eup =new Array(); var gld=new Array(); var common =new Array() When I got the result from each API calling; its company_data are set to its array value.
@Amir, I apologize, but I cannot understand what you are saying. Can you perhaps post what you expect common to look like? Seeing the result will help eliminate confusion and give you a working solution. (BTW, don't use new Array(); use [] instead.)
@Derek Sorry.. I will explain my requirement once again. In my list there is 2 different companies (Actually its value is dynamic depends up on different countries); I got 2 companies details in JSON format. Here I have 2 API for 2 Companies. company1.php and company2.php And I got 2 Different JSON data. But here the JSON both are same format that means Tags are same in Both JSON and only the values are different.Then I need to merge the values of 2 different JSON data to a common array.For this; var eur =new Array(); var gld=new Array(); var common =new Array();
1st api result set to Array "eru" and 2nd api result set to Array "gld".. currently this purpose is OK. To get the values as one ; I tried to set the values of two different arrays "eru and gld" to a Common Array. For this method; I tried; common.push(eup,gld); common.join(eup,gld); common.concat(eup,gld); alert(common.length) In this case; I got the common.length=2. But Actually I need the length "common.length=1". The concept is I need to set the values of both Arrays in to Common Array and shows as one... :(
