How to increment a numeric string value in angular js

Question

I have numeric value as a String and I want to increment its value. In java we used to do it with Integer.parseInt but I am not getting how to achieve this in angular.

My Controller Code:

var count="18"; 
jsonData["combinationsData"]
                                         .push( {
                                            "vAxis": count,
                                         "dataValue":dataValue
                                         } )
                                        count++;//I want to increment its value

I want to increment the count value to "19","20" so on, Please suggest how could I increment a String represented numeric value.

why are you using a string for a count in the first place? is this set somewhere else that doesn't allow for numbers? — Claies

count = "78";

count = ((+count)+1).toString();

console.log(count);

+count converts it to a number; +1 increments it; .toString() converts to it back to a string.

try this:

var count="18";  
jsonData["combinationsData"]
                                             .push( {
                                                "vAxis": count,
                                             "dataValue":dataValue
                                             } );
                                            count = (parseInt(count)+1).toString();

or:

var count=18;  
jsonData["combinationsData"]
                                             .push( {
                                                "vAxis": count.toString(),
                                             "dataValue":dataValue
                                             } );
                                            count++;

Use parseInt to get an int value out of your string value.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt

var myInt = parseInt(count);
myInt++;
