JavaScript method to delete elements with specified value from array

The following code uses two methods to delete elements of the array. The first one defines a separate function, and the second one defines a removeByValue method for the Array object.

Js code

function removeByValue(arr, val) {  
  for(var i=0; i<arr.length; i++) {  
    if(arr[i] == val) {  
      arr.splice(i, 1);  
      break;  
    }  
  }  
}  
var somearray = ["mon", "tue", "wed", "thur"]  
removeByValue(somearray, "tue");  
//somearray will now have "mon", "wed", "thur"

Add the corresponding method to the array object Method

Js code

Array.prototype.removeByValue = function(val) {  
  for(var i=0; i<this.length; i++) {  
    if(this[i] == val) {  
      this.splice(i, 1);  
      break;  
    }  
  }  
}  
var somearray = ["mon", "tue", "wed", "thur"]  
somearray.removeByValue("tue");  
//somearray will now have "mon", "wed", "thur"
