find and replace characters in string with array objects dynamically jquery

Question

My string is:

var str = "hi {0} your contact is {1}";

{0},{1} indicates dynamic data we can substitute to that string. Have to find "{0}" and replace it with objects in array where array contains:

var my_arr=[[{"data":"priya"},{"data":"reena"},{"data":"mathew"}],[{"data":"123456"},{"data":"745896"},{"data":"236521"}]]

and I want to replace {0} with my_arr[0] data and {1} with my_arr[1] data. Finally my output would be like this :

var result={"hi priya your contact is 123456","hi reena your contact is 745896","hi mathew your contact is 236521"}.

please help me to do this, any changes in array format can be acceptable. Thanks in advance.

Try below code.

var str = "hi {0} your contact is {1}";

var my_arr=[[{"data":"priya"},{"data":"reena"},{"data":"mathew"}],[{"data":"123456"},{"data":"745896"},{"data":"236521"}]]

var result = [];

$.each(my_arr[0],function(i) {
  var str = "hi {0} your contact is {1}";
  result.push(str.replace('{0}',my_arr[0][i].data).replace('{1}',my_arr[1][i].data));
});
console.log(result);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

(str.replace('{0}',my_arr[0][i].data) here I want to search dynamically like ' {'+i+'}'.where i can be 0,1,2..how could I do this — cindrella, May 06 '17 at 06:01

use nested loop and string replace like this

var my_arr=[[{"data":"priya"},{"data":"reena"},{"data":"mathew"}],[{"data":"123456"},{"data":"745896"},{"data":"236521"}],[{"data":"address1"},{"data":"address2"},{"data":"address3"}]]

var str = "hi {0} your contact is {1}  and address is {2}";
var new_arr =[];
  
for(i=0;i<my_arr.length;i++)
 {
     for(j=0;j<my_arr[i].length;j++)
     {
        if(i==0)
 {  
            str_1 = str.replace("{"+i+"}",my_arr[i][j]['data']);
            new_arr.push(str_1);
         }
 else
 {
     new_arr[j]=new_arr[j].replace("{"+i+"}",my_arr[i][j]['data']); 
        }
     }   
  }
 
console.log(new_arr);
