从JavaScript数组中删除字符串元素 [英] remove string element from javascript array

问题描述

可以有一个人告诉我，我怎样才能从数组中删除字符串元素
我有谷歌这一点，我得到的是由索引号删除

can some one tell me how can i remove string element from an array i have google this and all i get is removing by index number

我的例子：

 var myarray = ["xyz" , "abc" , "def"] ; 
 var removeMe = "abc" ; 

  myarray.remove(removeMe) ; 
  consle.log(myarray) ; 

这是我从控制台得到：

Uncaught TypeError: Object xyz,abc,def has no method 'remove' 

的jsfiddle

推荐答案

http://stackoverflow.com/a/3955096/ 711129 ：

Array.prototype.remove= function(){
    var what, a= arguments, L= a.length, ax;
    while(L && this.length){
        what= a[--L];
        while((ax= this.indexOf(what))!= -1){
            this.splice(ax, 1);
        }
    }
    return this;
}
var ary = ['three', 'seven', 'eleven'];

ary.remove('seven')

或者，使其成为一个全球性的功能：

or, making it a global function:

function removeA(arr){
var what, a= arguments, L= a.length, ax;
while(L> 1 && arr.length){
    what= a[--L];
    while((ax= arr.indexOf(what))!= -1){
        arr.splice(ax, 1);
    }
}
return arr;
}
var ary= ['three','seven','eleven'];
removeA(ary,'seven')

您必须自己做一个功能。您可以循环阵列上，并从那里删除元素，或有此功能为您代劳。无论哪种方式，它不是一个标准的JS特征

You have to make a function yourself. You can either loop over the array and remove the element from there, or have this function do it for you. Either way, it is not a standard JS feature.
