Delete an element from an array using its value in javaScript which supports IE8

Question

I want to delete one item from the array using its value instead of index which will work on IE8. Any help will be appreciated. Thanks.

Here is my array:

var myArray = ['one', 'two', 'three'];

The result should be something like:

delete operation:

myArray.splice('three');

result:

myArray =['one', 'two'];

I tried this but its not working in IE8.

angular.forEach($scope.leftList, function (leftItems) {
    var arrlen = $scope.rightList.length;
    for (var j = 0; j<arrlen; j++) {
        if (leftItems == $scope.rightList[j]) {
            $scope.rightList = $scope.rightList.slice(0, j).concat($scope.rightList.slice(j+1, arrlen));
        }
    }
});

What kind of values do you have in array, words only? One word per item? — skobaljic, May 07 '15 at 21:31
"*I want to...*" - but you've shown no code to suggest you've started on that; how far did you get? Where did you get stuck? — David says reinstate Monica, May 07 '15 at 21:32
Yes words only but it can contain more than one word per item. — user3842029, May 07 '15 at 21:33
Internet Explorer 8 is [*unsupported* and *untested*](https://docs.angularjs.org/guide/ie) as of Angular 1.3. Will you *only* be using AngularJS 1.2 for this project moving forward? — Sampson, May 07 '15 at 21:35
https://code.angularjs.org/1.2.28/docs/api/ng/function/angular.forEach does it internally handle IE8 not having Array.prototype.forEach? — Kevin B, May 07 '15 at 21:38
@user3842029 What exactly does "not working" mean? what error does it throw? what does it do instead of working? — Kevin B, May 07 '15 at 21:39

You can play with split and join methods and in the right moment also include some regex replace:

var myArray = ['one item', 'two', 'three', 'two', 'two', 'two', 'two', 'fourth item'];
function clearFromArray(item, array) {
 var re1 = new RegExp(item,"g");
 var re2 = new RegExp('(##)+',"g");
 return array.join('##').replace(re1, '').replace(re2, '##').split('##');
};
document.getElementById('result').innerHTML = clearFromArray('two', myArray);

<div id="result"></div>
