Print Page - syncronous prompt window / messager

Title: syncronous prompt window / messager
Post by: devnull on January 28, 2015, 07:21:48 PM

I need a synchronous dialog / window that allows me to have a few input elements for user input, rather than just one single element as per the jajascript prompt().

Can this be done ? - I need a callback once thse user clicks OK, but I also need to show a couple of comboboxes and inputs and return the data when the user clicks OK

Can the messager prompt be modified so that it parses the inputs in the dialog into a json string and sends that back as a single variable ?

Defining a customized dialog to achieve this functionality may be more appropriate.

Code:

function showPrompt(title, href, fn){
	var dlg = $('<div></div>').appendTo('body').dialog({
		width: 300,
		height: 150,
		title: title,
		href: href,
		modal: true,
		buttons:[{
			text: 'Ok',
			handler: function(){
				var d = $(this).closest('div.panel').find('div.panel-body');
				var json = d.find('form').serialize();
				fn(json);
				d.dialog('destroy');
			}
		},{
			text: 'Cancel',
			handler: function(){
				var d = $(this).closest('div.panel').find('div.panel-body');
				d.dialog('destroy');
			}
		}],
		onClose: function(){
			$(this).dialog('destroy');
		}
	}).dialog('dialog').find('.dialog-button').css('text-align','center')
}

Usage example:

Code:

showPrompt('Prompt', '_form.html', function(json){
  console.log(json);
});

Thanks, but what I am looking for is something similar to the standard javascript prompt() which freezes the calling script execution until a reply is received.

Using a callback from a normal window means that the calling code continues to run after the dialog is called.

The $.messager.prompt and the 'showPrompt' functions work asynchronously. The user can not pause the code executing after calling these functions.
