Uncaught ReferenceError: uneval is not defined
It works well with Firefox, but not work with Google Chrome.
I try:
var getSaved = [['ABC', 'http://...'], ['DEF', 'http://...'], ['...etc...']];
var get_saved_items = eval(getSaved);
var name = [], url = [];
for (var i = 0; i < get_saved_items.length; i++) {
name[i].push(get_saved_items[i][0]);
url[i].push(get_saved_items[i][1]);
};
window.localStorage.setItem('saved_name', uneval(name));
window.localStorage.setItem('saved_links', uneval(url));
it returns: Uncaught ReferenceError: uneval is not defined
What's the problem?
我相信uneval
只是在SpiderMonkey中,所以也只是基于Mozilla的浏览器。
Using 'eval' is not recommended because of different reasons (you can google it). uneval
will not work in other browsers.
For your requirement you can use a JSON parser. Widely used one is Crockford's JSON parser.
https://github.com/douglascrockford/JSON-js/blob/master/json2.js
var numbers = '[1, 2, 3, 4, 5, 6]';
var names = '["abc", "def", "ghi", "jkl", "mno", "pqr"]';
// string to Javascript object
var numbersObject = JSON.parse(numbers);
var namesObject = JSON.parse(names);
console.log(numbersObject);
console.log(namesObject);
// Javascript object to string
numbers = JSON.stringify(numbersObject);
names = JSON.stringify(namesObject);
console.log(numbers);
console.log(names);
