使用javascript从数组内部的字符串中删除双引号

I have an array like this: array = ["apple","orange","pear"] I want to remove the double quotes from the beginning and end of each one of the strings in the array. array = [apple,orange,pear] I tried to loop through each element of the array and did a string replace like the following

我有一个这样的数组:array = [“apple”,“orange”,“pear”]我想从数组中每个字符串的开头和结尾删除双引号。 array = [apple,orange,pear]我试图循环遍历数组的每个元素,并执行如下所示的字符串替换

    for (var i = 0; i < array.length; i++) {
        array[i] = array[i].replace(/"/g, "");
    }

But it did not remove the double quotes from the beginning and end of the string. Any help would be appreciated.Thanks much.

但它没有删除字符串开头和结尾的双引号。任何帮助将不胜感激。谢谢。

The only "'s I see in your Question are the quotes of the String literals contained in your array.

我在你的问题中看到的唯一“是你的数组中包含的字符串文字的引用。

["apple", ...]
 ^     ^

You probably aren't aware that

你可能不知道

A string literal is the representation of a string value within the source code of a computer program._(Wikipedia)

字符串文字是计算机程序源代码中字符串值的表示。(Wikipedia)

and should probably read the MDN article about the String object

并且应该阅读有关String对象的MDN文章

If you by accident mean the result of calling JSON.stringify on your array.

如果你偶然意味着在你的数组上调用JSON.stringify的结果。

var array = ["apple","orange","pear"];
JSON.stringify (array); //["apple", "orange", "pear"]

You can do so by replacing them

您可以通过替换它们来实现

var string = JSON.stringify(array);
    string.replace (/"/g,''); //"[apple,orange,pear]"
