【问题描述】：

我正在尝试删除数组中的双引号，数组如下所示。

let array: string[] = ["apple"," ","orange"," ","grape","art"," "," "]

【问题讨论】：

然后呢？ javascript没有裸词。字符串需要有引号，否则你的代码将无法工作

只删除空的双引号。

请在问题中相应指定。您可以使用过滤器功能为developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

【参考方案1】：

一个不好回答的问题！但只是为了你的知识。这甚至可以处理undefined。

let array = ["apple", " ", "orange", " ", "grape", "art", " ", " "];
let filtered = ["apple", " ", "orange", " ", "grape", "art", " ", " ", undefined].filter((x ="") => x.trim())
console.log(filtered)

【参考方案2】：

const array = ["apple"," ","orange"," ","grape","art"," "," "];
array.filter(element => element.trim());

【讨论】：

请不要只发布代码作为答案，还要解释您的代码的作用以及它如何解决问题的问题。带有解释的答案通常质量更高，更有可能吸引投票。

【参考方案3】：

         let array: string[] = ["apple"," ","orange"," ","grape","art"," "," "]



             let result = array.filter(function(item,pos,self)
                return item.length > 1;
                )

          console.log(result)
