我正在动态填充数组,该数组基于页面id
标记上的所有video
。
如何从每个数组项的值中删除单词dog
?到目前为止,这是填充的数组,我只需要为每个数组项删除单词dog
:
var players = new Array();
$("video").each(function(){
players.push($(this).attr('id'));
});
所以它会来自:
["video_12_dog", "video_13_dog"]
为:
["video_12", "video_13"]

您可以迭代数组并在每个元素上调用replace()
(作为字符串):
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"]
