How do I traverse the Jsonc object? In fact, the method is very simple.
For example, you have the following JSON object:
var obj ={"name": "Feng Juan", "Password": "123456″," "Department": "Technical department", "Sex": "female", "old": 30};
Traversal method:

Copy Code code as follows:

For (var p in obj)
{
str = str+obj[p]+ ', ';
return str;
}
