I want to extract the three variables (friendCount, pnCount, and allCount) out of a string representation of the following Object:
'{"friendCount":5,"pnCount":0,"allCount":5}'
I thought about using a RegEx or similar, but I have no further Idea. The numbers in the string may be between 0 and about 100
If that is a string, than parse it...
var str = '{"friendCount":5,"pnCount":0,"allCount":5}';
var obj = JSON.parse(str);
console.log(obj.friendCount, obj.pnCount, obj.allCount);
If it is already an object, just reference it
var obj = {"friendCount":5,"pnCount":0,"allCount":5};
console.log(obj.friendCount, obj.pnCount, obj.allCount);
Try this
var data= {"friendCount":5,"pnCount":0,"allCount":5}
var friendCount = data.friendCount;
var pnCount = data.pnCount;
var allCount = data.allCount;
If you want Regex it can be done like this:
var re = /([\w]+)":(\d+)/g;
var str = '"friendCount":5,"pnCount":0,"allCount":5';
var m;
while ((m = re.exec(str)) !== null) {
if (m.index === re.lastIndex) {
re.lastIndex++;
}
// View your result using the m-variable.
// eg m[0] etc.
}
