jQuery UI dialog window - how to not execute script if user clicks cancel

JavaScript
1

Here we have one simple modal window, how can I take action based on what is inside the variable ajaxReq.

window.ajaxReq = true;
$( “#dialog-confirm” ).dialog({
resizable: false,
height: “auto”,
width: 400,
modal: true,
buttons: {
“Confirm”: function() {
$( this ).dialog( “close” );
},
“Cancel”: function() {
window.ajaxReq = false;
$( this ).dialog( “close” );
}
}
});

if(ajaxReq == false) { return; }

The ajaxReq here above is evaluated as true, I wonder what is the technique for initializing the variable, but getting the data after somebody clicks cancel.

If tou use Redux you can take action on the changes of state which can include this variable that you care about.

Note: when you include code blocks in a post, enclose them between three backticks (```) at the beginning and the end to keep the formatting, e.g.,

Some code
      More code
           Even more code

You can define functions to be executed when a dialog is opened or closed, e.g.,

window.ajaxReq = true;
$( “#dialog-confirm” ).dialog({
	resizable: false,
	height: “auto”,
	width: 400,
	modal: true,
	open: function () {
		openFunction();
	},
	close : function() {
		closeFunction();
	},
	buttons: {
		"Confirm": function() {
			$( this ).dialog( “close” );
		},
		"Cancel": function() {
			window.ajaxReq = false;
			$( this ).dialog( “close” );
		}
	}
});

function openFunction() {
	alert("The dialog is open.");
}

function closeFunction() {
	alert("The dialog is closed.");
	if(ajaxReq == false) { return; }
}

and do whatever you need to within the closeFunction, in this case.
