Question

im trying to find a way to alert when there is a null values in an object, if its present it should alert fail and if it doesn’t it continues with the another action. Currently im able to alert for each key. with this code:

var ave = {
 'a': '02',
 'b': '04',
 'c': '',
 'd': '',
 'f': '07'
 };

var total = 0
$.each(ave, function(key, value) {
  var numbersA = total + value.length;
    if (numbersA === 0) {
       alert("Fail!");
     } else {
       alert("Pass!");
     }
});

It pops up Fail! twice and Pass 3 times. i want it to alert fail even if there is single null value present in the object. Is there way to do it?

I would use a for in loop; jQuery’s jQuery.each isn’t well-suited to this situation.

var ave = {
 'a': '02',
 'b': '04',
 'c': '',
 'd': '',
 'f': '07'
};

var success = true;

for(var x in ave) {
    if(ave.hasOwnProperty(x)) {
        if(ave[x] === '') {
            success = false;
            break;
        }
    }
}

if(success) {
    alert('Pass!');
} else {
    alert('Fail!');
}
