Ajax function prevents redirection?

posted 10 years ago

I 'm deleting records with ajax code (in a javascript function):

       $.ajax({
                type: "DELETE",
                url: "{{ URL::to('admin/categories/" +idtoedit +"')}}",
                success: function (result) {
                    alert('success');
                }
            });

The alert message does not show up. The records do get deleted. The code in my controller's destroy method *does get executed:

public function destroy($id) {       
       $category = Category::find($id);
       $category->delete();   
       return Redirect::to('admin/categories' )
                            ->with('message', 'Successfully updated page!');
    }

(I checked code execution with NetBeans) But redirection does not happen.

Also, I commented out all the code in the function and tried to echo something out. return 'hii'; Nothing was echoed.

Solution

You can not echo directly nor redirect inside ajax call. What you need is to echo or redirect using javascript/jquery inside ajax callback

So e.g. in controller you have

public function destroy($id) {       
       $category = Category::find($id);
       $category->delete();   
       return 'success'; //not the best value to return, but for illustration :)
    }

Then in jquery. This will alert the 'success' string from controller

$.ajax({
     type: "DELETE",
     url: "{{ URL::to('admin/categories/" +idtoedit +"')}}",
     success: function (result) {
        alert(result);  
     }
});

If you want to redirect, you must do it in jquery too

$.ajax({
    type: "DELETE",
    url: "{{ URL::to('admin/categories/" +idtoedit +"')}}",
    success: function (result) {
         window.location.replace('/admin/categories');  
    }
});

Thanks! It works fine!! Only one change needed: window.location.replace('categories'); instead of 'admin/categories'.

It worked fine in Laravel 4, but I'm trying it in Laravel 5 and doesn't work. I replaced and {{ }} with {!! !!}

url: "{!! URL::to('admin/categories/" +idtoedit +"')!!}",

This also does not work!
