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

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

"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 Thomas

Yes words only but it can contain more than one word per item. — user3842029

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>

Also on Fiddle.
