转换数组对象数组

Question

怎么可以将我的数组转换：

["Collaboration", "Personal", "Services", "Financial", "Enginerring", "Infrastructure", "Application", "null"] 

对象的数组：

["title": "Collaboration", "title":"Personal", "title":"Services", "title":"Financial", "title":"Enginerring", "title":"Infrastructure", "title":"Application", "title":"null"] 

我做这样的事情：

var mainmenu = []; 
for(var i=0; menus.length > i;i++){ 
    mainmenu[i] = "{title:"+menus[i]+"}"; 
} 

但我得到了：

["{title:Collaboration}", "{title:Personal}", "{title:Services}", "{title:Financial}", "{title:Enginerring}", "{title:Infrastructure}", "{title:Application}"] 

那么怎么可能不用双引号呢？

Answer 1

尝试使用.map

var data = ["Collaboration", "Personal", "Services", "Financial", "Enginerring", "Infrastructure", "Application", "null"]; 
 
var result = data.map(function (title) { 
 
    return { title: title }; 
 
}) 
 

 
console.log(result);

在你的代码的问题，您正在使用String代替Object，删除"

mainmenu[i] = { title: menus[i] }; 
       ^^^ ^^ ^^  ^^^ 

Answer 2

这是因为您正在创建字符串而不是实际的对象。像这样创建对象：

mainmenu[i] = { 
    title: menus[i] 
}; 

Answer 3

ES6

var data = ["Collaboration", "Personal", "Services", "Financial","Enginerring", "Infrastructure", "Application", "null"]; 
data.map(function(title) { 
    return { 
     title: title 
    } 
}) 

ES5

for(var i = 0;i < data.length;i++) { 
    data[i] = {title: data[i]} 
} 

Answer 4

这是一个很好的例子，其中可以使用Array.from()：

的Array.from（）方法从创建一个新的Array实例一个 数组式或可迭代的对象。

在ES6中，类语法允许用户定义的类的内置和 的子类;因此，类方静态方法（如 Array.from）通过Array的子​​类“”继承“”，并创建子类的新实例 而不是Array。

var data = ["Collaboration", "Personal", "Services", "Financial", "Enginerring", "Infrastructure", "Application", "null"]; 
 
console.log(Array.from(data, x => ({title : x})));
