Unable remove specifc value from array using jQuery [duplicate]

Question

I have got an array

And i am trying to remove a specfic element from the array

I tried this way

var existingLabels = [1, 2, 3, 2, 2, 4];


var loc_name = 1;

 existingLabels = $.grep(existingLabels, function(loc_name) {
  return loc_name != loc_name;
});

alert(existingLabels);

Are you trying to remove the first array element, or the array element that has a value of 1? Obviously they're the same in this example, which is why I need clarification. — j08691

@j08691 The same, however OP's problem is that he picked unfortunate name for current iteration element inside grep callback. — dfsq

Comparison condition inside grep callback makes no sense because of unfortunate variable name:

return loc_name != loc_name; // always false

Corrected script:

existingLabels = $.grep(existingLabels, function(el) {
    return el != loc_name;
});
