如何从Jquery中的嵌套函数调用变量

Question

I wanted to get the value of chkArray variable when called outside the method.

When I called getValues().total from outside the method I am getting a error message as cannot read property total of undefined.

function getValues(){
chkArray = new Array() ;
$("input[type=checkbox]:checked").each(function fire() {
 var total = chkArray.push($(this).val());
console.log(chkArray)    
});
};

Kindly, help how to call that variable outside the method

Answer 1

Use this:

  function getValues(){
     var total = new Array() ;
     $("input[type=checkbox]:checked").each(function fire() {
       total.push($(this).val());
      });
   return total;
  };

Call function

var total= getValues();
console.log(total);

Answer 2

 function getValues() { var total = new Array(); $("input[type=checkbox]:checked").each(function() { total.push($(this).val()); }); return total; }; function doSomething() { var k = getValues(); console.log(k); }
