Replace string in JSON with JavaScript

Question

I have a simple JSON on which I would like to replace one string from one property. Let's say this is my JSON :

var values = [
    { id: 10, url: "www.mydomainname.com/images\uploads\xfolder\FILE_NAME.JPG", longitude: 121.256248, latitude: 19347774275 },
    { id: 11, url: "www.mydomainname.com/images\uploads\xfolder\FILE_NAME.JPG", longitude: 121.7534025, latitude: 19347868 },
    { id: 12, url: "www.mydomainname.com/images\uploads\xfolder\FILE_NAME.JPG", longitude: 121.85458, latitude: 1934748775 },
    { id: 13, url: "www.mydomainname.com/images\uploads\xfolder\FILE_NAME.JPG", longitude: 121.5525, latitude: 19317868 }
]

Now what I would like to do is to replace every \ with a slash / . For example :

from url: www.mydomainname.com/images\uploads\xfolder\FILE_NAME.JPG to url: www.mydomainname.com/images/uploads/xfolder/FILE_NAME.JPG

What I tried was very simple. This is what I tried :

for(i = 0; i < values.length; i++){
    var str = values[i].url;
    var res = str.replace("''\''", "/");
}

But it didn't work. Any help would be highly appreciated, since it's been a while I've been stucked Thanks in advance :)

firslty, that isn't JSON - it's a javascript array of javascript objects — Jaromanda X

what is "''\''" you'll want a regex for the search value for a start ... values[i].url = values[i].url.replace(/\\/g, '/') — Jaromanda X

You're never doing anything with res currently. Use a regular expression with a global flag instead:

var values=[{id:10,url:"www.mydomainname.com/images\\uploads\\xfolder\\FILE_NAME.JPG",longitude:121.256248,latitude:19347774275},{id:11,url:"www.mydomainname.com/images\\uploads\\xfolder\\FILE_NAME.JPG",longitude:121.7534025,latitude:19347868},{id:12,url:"www.mydomainname.com/images\\uploads\\xfolder\\FILE_NAME.JPG",longitude:121.85458,latitude:1934748775},{id:13,url:"www.mydomainname.com/images\\uploads\\xfolder\\FILE_NAME.JPG",longitude:121.5525,latitude:19317868}];
values.forEach(value => value.url = value.url.replace(/\\/g, '/'));
console.log(values);

for(var i=0; i < arr.length; i++) {
 arr[i] = arr[i].replace(/\\/g, "/");
}
