Remove object from array object Jquery

Question

I am creating array object like follows:

var numberOfSameDeficiency = [];
 for (var i = 0; i < result.length; i++) {
 var deficiencyId = result[i].Deficiency_Id;
 var deficiencyName = result[i].DeficiencyName;
 //check to see if this deficiency is already in the list of available selections
 if ($("#drpDeficiency option[value='" + deficiencyId + "']").length == 0) {
 var option = $('<option>');
 option.attr('value', deficiencyId);
 option.text(deficiencyName);
 $select.append(option);
 }
 else {
 Tests = {};
 Tests.TestId = testId;
 Tests.DeficiencyId = deficiencyId;
 numberOfSameDeficiency.push(Tests);
 }
 }

And I want to remove object on different function like this:

for (var i = 0; i < result.length; i++) {
 console.log(numberOfSameDeficiency);
 var isFound = false;
 var deficiencyId = result[i].Deficiency_Id;
 if (numberOfSameDeficiency) {
 numberOfSameDeficiency.forEach(function (entry) {
 if (entry.DeficiencyId != deficiencyId) {
 isFound = true;
 **numberOfSameDeficiency.splice(entry, 1); // Generating Error (Remove all items from array object)** 
 return;
 }
 });
 // console.log("end if");
 }
 if (!isFound) {
 $("#drpDeficiency option[value='" + deficiencyId + "']").remove();
 }
 }

So what line code should be there to remove particular object from array object.

Answer 1

Try this

for( i=myArray.length-1; i>=0; i--) {
 if( myArray[i].field == "money") myArray.splice(i,1);
}

This also works

myArray = [{name:"Alpesh", lines:"2,5,10"},
 {name:"Krunal", lines:"1,19,26,96"},
 {name:"Deep",lines:"3,9,62,36" }]
johnRemovedArray = myArray
 .filter(function (el) {
 return el.name !== "Krunal";
 });

• JDandChips: I think this is right. In your code you are affecting the original list you are calling forEach on - this is not good. for loop doesn't care about the contents of the array, just length

Answer 2

Create this prototype function:

Array.prototype.removeElement = function (el) {
 for(let i in this){
 if(this.hasOwnProperty(i))
 if(this[i] === el)
 this.splice(i, 1);
 }
}

Then call:

let myArray = ['a','b','c','d'];
myArray.removeElement("c");

It also works with objects:

let myObj1 = {name: "Mike"},
 myObj2 = {name: "Jenny"},
 myArray = [myObj1, myObj2];
myArray.removeElement(myObj2);
