Hello, I want to rollback a page using JavaScript. for that, I use the following syntax:
new mw.Api().postWithToken('rollback', {
action: 'rollback',
title: 'pageName',
user: 'userName'
});
If the rollback has not succeeded (e.g., if the user does not have the necessary right), I would like to display an error message. How can I check if the rollback has been succeeded?
You'll need to look at the returned parameters and possible errors in API:Rollback#Returned_fields.
@Ciencia Al Poder: Thank you, but I didn't understand how can I get the returned parameters using JavaScript. I tried the following:
new mw.Api().postWithToken('rollback', {
action: 'rollback',
title: 'pageName',
user: 'userName'
}).then(function (data) {
if (data && data.error) {
alert( data.error[info] );
}
});
If the rollback fails, I expect to see an alert box with the error message; however, nothing happens...
According to the documentation, you should use .done()
Try to add console.log( data ); and see the console output for the details
