Stop function if condition is true

rated 0 times [ 190] [ 6] / answers: 1 / hits: 18594 / 10 Years ago, sat, may 10, 2014, 12:00:00

I use the Array map() Method to check each element in an Array and if the condition in the if clausel is true i call another function.

$.map(data['icd'], function (field, i) {

   if(field.nummer == search){

      Diagnose.single(field.id);

   };

});

Now my problem is that i want to stop the map method if a element fullfills the if condition. Because i noticed that when i have for example 6 elements that fullfill the condition the function Diagnose.single(field.id); is called 6 times instead of once!

I tried:

$.map(data['icd'], function (field, i) {

   if(field.nummer == search){

      Diagnose.single(field.id);

      return true;

   };

});

But this didnt worked! What can i do instead? Thanks

Use simple for-loop with break statement:

for (var i = 0; i < data['icd'].length; i++) {

   if (data['icd'][i].nummer == search){

      Diagnose.single(data['icd'][i].id);

      break;

   };    

}

map is used for different tasks.
