如何在angularJS中将字符串转换为数组

Question

Actually, I am receiving array in response with slashes so, I did this.

what I receiving on the response

[{\"name\":\"title\",\"value\":\"%post_title%\"},{\"name\":\"author\",\"value\":\"%author_name%\"}]

so I did this

var b=JSON.stringify(response.data);
var str = b.replace(/\\/g, '');

after this, I have a string like

["{"name":"title","value":"%post_title%"}","{"name":"author","value":"%author_name%"}","{"name":"wordcount","value":"%wordcount%"}","{"name":"logged_in","value":"%logged_in%"}","{"name":"page_id","value":"%page_id%"}","{"name":"post_date","value":"%post_date%"}"]

now, how can I again covert this to the array so I use it in ng-repeat?

Answer 1

You should use JSON.parse() to create an array:

 let str = '[{\\"name\\":\\"title\\",\\"value\\":\\"%post_title%\\"},{\\"name\\":\\"author\\",\\"value\\":\\"%author_name%\\"}]'; console.log(JSON.parse(str)); 

 .as-console-wrapper { max-height: 100% !important; top: 0; } 

Answer 2

你可以使用JSON.parse。

const myNewArray = JSON.parse(str);

Answer 3

use angular.fromJson()

$scope.x = '[{\"name\":\"title\",\"value\":\"%post_title%\"},{\"name\":\"author\",\"value\":\"%author_name%\"}]';

 console.log(angular.fromJson($scope.x));

otherwise use JSON.parse()

console.log(JSON.parse($scope.x));

Answer 4

You can use JSON.parse() :

var array = JSON.parse(`[
    {"name":"title",  "value":"%post_title%"}, 
    {"name":"author", "value":"%author_name%"}
]`);
