How can I show a confirm message before submit form data?

How can I show a confirm message before submit form data and if the result of confirm is false to cancel the submit action?
The following code is not working while the $.messager.confirm() working asynchronous.

Code:

	    onSubmit: function(param){ //Fires before submit, return false to prevent submit action.
	    	if($(this).form('validate') == false) { //validate form data
	    		$.messager.alert(infoTitleInvalidInput, infoTitleInvalidMsg, "error");
	    		return false;
	    	};
	    	
	    	$.messager.confirm(infoTitleConfirm, confirmEdit, function(r){
			if (r) {  return true;}
	    	});
		return false;
	    },

Please try this:

Code:

$('#ff').form({
	onSubmit:function(){
		var f = this;
		var opts = $.data(this, 'form').options;
		if($(this).form('validate') == false){
			return false;
		}
		$.messager.confirm('Confirm','Are you sure?',function(r){
			if (r){
				var onSubmit = opts.onSubmit;
				opts.onSubmit = function(){};
				$(f).form('submit');
				opts.onSubmit = onSubmit;
			}
		})
		return false;
	}
});
