[英]Create array of json objects from array values
I have an array 我有一个阵列
var names = ["bob", "joe", "jim"];
How do I get the array to be a array of objects like so? 如何让数组成为这样的对象数组?
var nameObjs = [{"name":"bob"},{"name":"joe"},{"name":"jim"}];
I've tried doing a loop and adding { and } manually but the loop just ends up getting to big, but I feel like something like JSON.stringify would be the 'correct' way of doing it. 我已经尝试过循环并手动添加{和}但循环最终变得很大,但我觉得像JSON.stringify之类的东西将是'正确'的方式。
Why not this? 为什么不呢?
// Get your values however rou want, this is just a example
var names = ["bob", "joe", "jim"];
//Initiate a empty array that holds the results
var nameObjs = [];
//Loop over input.
for (var i = 0; i < names.length; i++) {
nameObjs.push({"name": names[i]}); //Pushes a object to the results with a key whose value is the value of the source at the current index
}
The easiest way I know of is: 我所知道的最简单的方法是:
var names = ["bob", "joe", "jim"];
var namesObjs = []
for (var i = 0; i<names.length; i++) {namesObjs.push({name:names[i]})}
This is with a loop, but not that big 这是一个循环,但不是那么大
You make a function to do this: 你做了一个功能:
function toObj(arr) {
obj=[];
for (var i = 0; i<arr.length; i++) {obj.push({name:arr[i]})}
return obj;
}
If you don't need names
afterward... 如果你以后不需要
names
......
var names = ["bob", "joe", "jim"],
nameObjs = [];
while (names.length) {
nameObjs.push({
'name': names.shift()
});
}
or even... 甚至...
var names = ["bob", "joe", "jim"],
n;
for (n in names) {
names[n] = {'name': names[n]};
}
