I have a JavaScript popup "confirm dialogue" setup on some links, when the link is clicked it says "are you sure?" and lets u confirm or cancel, however the ajax call will work regardless of what you choose.
<a onclick="return confirm(\'Are you sure?\')" class="sendEmailLink" href="/" id="someID">Send</a>
The function called starts as follows:
$$('.sendEmailLink').addEvent('click', function(e)
{
e.stop();
(I assume something should go here)
var myRequest = new Request.JSON({
etc...
It makes sense the confirm dialogue would not stop the above code, but I cant get my head around how I can accomplish this in mootools. Help?
I need a dialogue box offering a choice of yes or no, if yes then continue with ajax request, if not then do not continue with request.
Thanks.
Like #Marcin mentioned, you are binding two click events to one element, so it is no wonder that your ajax call proceeds as usual irrespective of the result of the confirm dialog.
Eliminate one, by not binding event to an element via an onclick attribute. (Never use onclick!)
element.addEvent('click', function() {
if (confirm('Are you sure?')) {
new Request.JSON({
// ...
}).send();
} else {
// Do nothing
}
});
Here is a relevant jsFiddle for you to play around with.
Here is solution: http://jsfiddle.net/kVjAB/
Some comments:
Do not use $$ or $ in Mootools anymore. They are deprecated.
In your code you are binding click event to link. Also, you have added attribute onClick which will run itself code first, then your binded code. It is like you add two separate events to link.

I have a button.when click button, show a dialog to select data.
If click the button so fast,multi dialog will be show.
At present，I have two way to solve this problem
1.use disabled
2.use setTimeout and clearTimeout
have any other better way to solve this problem?
thank you very much
explain:
if use disabled,after dialog close,need to set the button available.
at present,I use this code
Util.prototype.lazyTriggerEvent = function(buttonId,event,callback){
var searchTrigger=null;
$("#"+buttonId).bind(event,function(){
var text = $.trim($(this).val());
clearTimeout(searchTrigger);
searchTrigger = setTimeout(function(){
callback(text);
},500);
})
};
//Util.lazyTriggerEvent("showDialgBtnId","click",function(){})
if click button trigger a ajax，and have much more button like this，is a best common way to solve this problem.
You can use jquery's .one() handler which limits a function to running once:
JQuery's .one() handler
Description: Attach a handler to an event for the elements. The
handler is executed at most once per element per event type.
$('button').one('click', function() {
// Do stuff
});
Or you can also disable the button on click:
$('button').click(function() {
$(this).prop('disabled', true);
// Do stuff
});
To re-enable the button, you can simply add the following to your close modal function:
$('button').prop('disabled', false);
I suppose when you want to show a dialogue, you execute a function called showDialogue() .
In your showDialogue(), you'll be able to check whether your dialogue was initiated.
Keep your mind off the button. Focus on the showDialogue().
If your dialogue was initiated, then do not execute the rest of your code in showDialogue(), as if showDialogue() isn't executed twice. It gives an illusion that the multi click isn't working. Is it the solution you desire, without disable and setTimeout?
Use disabled at first, and then when the dialog displays, enable the button.
I've a very simple question, but I can't find the correct way to resolve.
I have a phonegap app wich has a login, and I check the results with ajax.
I check the form when the user click:
GO
The order of the instructions are:
1- The user clik GO.
2- Check the form inputs.
3- IF they'e corrects, go home.html
I can't do a
window.location.replace('index.html');
because I lost the data-transition.
Another option could be make a link hidden, and trigger his click when necesary, but I dont like it.
The best way it's when click at Go, do something, and if It's necesary go to his href.
Thanks for all !
$("a").click(function(e){
// Do what all checks you need to do here
if(something is wrong)
{
// Do stuff here
e.preventDefault(); // Stop propagation of default event.
return false;
}
});
This way the data-transition will also work, becaue the default event will be stopped only when the validation fails.
You could implement an onclick function and do preventDefault if the conditions for progressing to the link url aren't fulfilled. Have a look at this question:
preventDefault inside onclick attribute of a tag
If you are using ajax, then why dont you return 'true' or 'false' value depending upon the validation result that you are performing.
Then in your 'success function' of ajax, you can check if the result is 'true' or 'false', and if validations are 'true', you can use window.location.href method of javascript.
Every time I press a button, there is a random chance that a alertify alert window popups. The alertify alert popup is something I use instead of javascript Alert, just to get a nicer design.
Alertify library
And here is a screenshot of the current situation:
I want to assign a event to the OK button. When I use the "inspect element" function in google chrome, I see that this green OK button has an id called "alertify-ok", so I want to assign an event when this button is pressed.
I've tried to add this part to my HTML document in the script part:
$( "#alertify-ok" ).on( "click",function() {alert("finally");});
But nothing happens. The reason why I need this to work, is that the youtube popupmodal should come up right after I've pressed the OK button. I belive the error comes because the alertify window with HTML is from an external library, so how can i do this?
Alerts and the others take callback functions on creation, https://github.com/alertifyjs/alertify.js/blob/0.3.12/src/js/alertify.js#L608. You don't need to attach another event listener, just give it the function you want it to execute. example below:
alertify.alert("alerttext", function(e) {
functionIWantToCall();
});
You can put the event on an element you know is already existent (like "body") and specify it to trigger only when the wanted element is clicked:
$(" body").on({
click: function () {...
}
}, "#trigger");
I am using a OnePage template of bootstrap, I can not click a link, or can not switch a radio button, someone says I am using e.preventDefault()
Open this page http://abi.maxinrui.com/, you will see what I mean when you click "Click me" on that page.
I check the js file, there are lots of e.preventDefault() and I don't know how to modify them.
Is there a way to disable e.preventDefault()?
I want to have some hyperlink to another websites in my OnePage templete, so here is what I am think: I give some particular elements an ID or class, then I write some js, to disable e.perventDefault() only for these elements.
Does anybody know how to do that?
Thanks!
If you're using jQuery to handle your events, then it's possible!
First, a fiddle (shell for full effect): http://fiddle.jshell.net/UN5WE/show/
Here's the actual fiddle to edit: http://jsfiddle.net/UN5WE/
Basically, we're modifying jQuery's Event object, and specifically, the preventDefault method found on the prototype. We maintain a reference to re-enable preventDefault.
EDIT
For your specific use case, here's a way to disable preventDefault (based on a class). Just run this script after jQuery has loaded:
jQuery.Event.prototype.preventDefault = (function(){
var originalFunc = jQuery.Event.prototype.preventDefault;
return function(){
if($(this.target).hasClass('disableDefault')) {return;}
originalFunc.call(this);
}
}())
Prior to calling preventDefault, this will check to see if the target has a disableDefault class. If it does, it returns immediately (allowing the default to happen). To test your page, copy that code into your console and then run: $('h1').addClass('disableDefault').
I don't think is possible, or at least not on an easy way that i can think of, you can unbind the handlers if they were setted using bind, but that will also remove any behavior that they have, but you can use a workaround, add a new event handler for your links, i recommend that you add a special class to external anchors and then get the href attribute from it and open a new tab using window.open like this:
http://jsfiddle.net/yV78E/2/
The html
Hey
The js
// Similar behavior that might be on your site
$('a').click(function(e){
e.preventDefault();
// some code
});
// Use the code below as a workaround
$('.externalLink').click(function(e){
var targetLink = $(this).attr('href');
window.open(targetLink, '_blank');
});
You only need the second part of the script above, since the first one is just to emulate your problem.
I have an onbeforeunload event :
$().ready(function() {
window.onbeforeunload=function() { return "haha" };
});
And my links are like this (ajax web site) :
<a href="#pageX" />
But the onbeforeunload is never called. What can i do ?
Thanks
I'm guessing since you're trying to bind to the onbeforeunload and return a string, that you're looking to provide the user with an "Are you sure you want to leave this page" dialog on an AJAX site.
In which case you probably need to go about this a little differently by binding a click handler onto the links. So you can prevent the hash change until the confirmation is made.
Something like:
$('a[href^="#"]').live('click',function(e){
if( //should we be confirming first? ) {
//put your confirmation code here either using default JS windows or your own CSS/jQueryUI dialog boxes
// this code should either cache the url of the link that was clicked and manually update the location with it when the user confirms the dialog box (if you're using JQUI windows) or simply use JS confirmation boxes and based on the response, all you need to do is return; and the link click will handle normally
e.preventDefault(); //prevent the link from changing the hash tag just yet
e.stopImmediatePropagation(); //prevent any parent elements from firing any events for this click
}
} );
Don't get me wrong, but are you serious ?
That link just refers a hash-tag, hence, it will not leave the current site and there will be no call to onbeforeunload nor unload.
If there is any *click event handlerbound to that anchor aswell, there must be something in the event handler code which really forces the current site to get unloaded (location.href` for instance).
If you just switch HTML via Ajax, there is no onbeforeunload aswell.
You could bind a handler to the onhashchange event (check browser compatibilty) but that would fire for any change that happens in your url/hash.
You're probably looking for the onhashchange event:
