You can’t do that, but you could use/write your own dialog which is displayed using DOM elements (like phoenix suggested, it just doesn’t have to be that particular jQuery plugin, you could write your own or use plugin from another JS framework). The “use jQuery + plugin X” answers are starting to get annoying. There … Read more
Instead of using WinForm MessageBox, use the MessageBox provided by WPF and later use MessageBoxResult instead of DialogResult in WPF. like: MessageBoxResult messageBoxResult = System.Windows.MessageBox.Show(“Are you sure?”, “Delete Confirmation”, System.Windows.MessageBoxButton.YesNo); if (messageBoxResult == MessageBoxResult.Yes) //………..
It is not possible. This window is displayed by the browser using the platform’s UI kit. It’s not in the DOM, not visible from the CSS or Javascript, there’s nothing you can do. However, some very simple jQuery code can do the trick. How about $(‘a’).confirm(); ?
You need the modal in your HTML. When the delete button is clicked it popup the modal. It’s also important to prevent the click of that button from submitting the form. When the confirmation is clicked the form will submit. $(‘button[name=”remove_levels”]’).on(‘click’, function(e) { var $form = $(this).closest(‘form’); e.preventDefault(); $(‘#confirm’).modal({ backdrop: ‘static’, keyboard: false }) .on(‘click’, … Read more
Unfortunately, there is no cross-browser support for opening a confirmation dialog that is not the default OK/Cancel pair. The solution you provided uses VBScript, which is only available in IE. I would suggest using a Javascript library that can build a DOM-based dialog instead. Try Jquery UI: http://jqueryui.com/
A simple inline JavaScript confirm would suffice: <form onsubmit=”return confirm(‘Do you really want to submit the form?’);”> No need for an external function unless you are doing validation, which you can do something like this: <script> function validate(form) { // validation code here … if(!valid) { alert(‘Please correct the errors in the form!’); return false; … Read more
Update (2017) Modern browsers now consider displaying a custom message to be a security hazard and it has therefore been removed from all of them. Browsers now only display generic messages. Since we no longer have to worry about setting the message, it is as simple as: // Enable navigation prompt window.onbeforeunload = function() { … Read more
