javascript - how to print the return value of a function in jquery -

i want print return value function

$(document).ready(function () {     $('.click').click(function (e) {         var value = 1;         check(value); //function call value:value=1         alert(val); //here want return value function     });     function check(value) {         if (value == 1) {             var val = 'success';             return val;         } else {             var val = 'error';         }     } }); //document ready function 

so how acieve return value of function , print value of function returned

you this:

var value = 1; var valofvalue = check(value); //function call value:value=1 alert(valofvalue); //here want return value function 

or, shorter:

var value = 1; alert(check(value)); 

the reason wasn't working because val not global variable - made in check() function , no 1 other things inside check() can access it. made variable, valofvalue, store return value , use in click function.

even better, save making multiple variables, put val variable way @ top of function, don't need return anything:

$(document).ready(function () {    var val = '';     $('.click').click(function (e) {     var value = 1;     check(value);      alert(val);   });    function check(value) {     if (value == 1) {         val = 'success';     } else {         val = 'error';     }   } });
