Remove a common word from each string value in an array

Question

I am populating an array dynamically which is based on all the ids on the page's video tags.

How can I remove the word dog from each array item's value? Here is the populated array so far, I just need to remove the word dog for each array item:

var players = new Array();
$("video").each(function(){ 
    players.push($(this).attr('id'));
});

So it would go from:

["video_12_dog", "video_13_dog"]

to:

["video_12", "video_13"]

What would the array look like before and after this removal? Have you tried anything yet? — ajp15243

It would go from: ["video_12_dog","video_13_dog"] to: ["video_12","video_13"] — Andrew Howard

Squint that's not my question. My question is not to REMOVE a whole item, but to remove part of it's value! — Andrew Howard

You can edit the before-and-after arrays into your question, so that people immediately see it. Will the strings within the array always be formatted that way? Also, people may be reluctant to help without you showing some attempt. — ajp15243

If I had a dollar for every time someone used $(this).attr('id') instead of this.id, I'd be ... slightly well off. — Alnitak

You could iterate over the array and call replace() on each element (as string):

function removeWord(arr, word) {
    for (var i = 0; i < arr.length; i++){
        arr[i] = arr[i].replace(word,'');
    }
}
var aaa = ['value_1_dog', 'value_dog_2', 'dog_value3'];
removeWord(aaa, 'dog');
console.log(aaa); // ["value_1_", "value__2", "_value3"]

var question = ["video_12_dog","video_13_dog"]
removeWord(question, '_dog');
console.log(question); // ["video_12","video_13"]
