Topic: JQuery Selectors - add events to button's or other elements

Hi Chris,

first week with your wunderfull framework, but now my first post in this forum.
I can see that a html 'onclick' can be rendered on all kind of elements, but I would like to address them with javascript, and / or JQuery

Somehow the framework unbinds my click event is that correct?
Or can I use thinks like this? - Add a click event on all buttons with class iPush?

<code>
$(document).ready(function() {

     $(".iPush").live('click', clicktest);
     
});


function clicktest() {
     alert('this class has been clicked');
}
</code>

Vincent

Re: JQuery Selectors - add events to button's or other elements

Hi,

It doesn't unbind but the WAn handler is on top of classic handlers (useCapture = true).
This may affect only async links or special elements with WebApp.Net "rel" attribute values.

If you confirm it doesn't work on classic element I'll take a look into this problem.

Re: JQuery Selectors - add events to button's or other elements

JQuery on classic selectors worked now. Must be a conflict with another .js library (RGraph for Canvas rendering)

Changed the order of .js includes and now all JQuery selectors are working fine.

Re: JQuery Selectors - add events to button's or other elements

Hi Chrilith,

Im usign WAN for some time, and know using jquery i have problems to execute a command from a link 'a'

i'm making a ajax request form Picasa, and populate a layer using jquery, but i cant make the function works, when created.

This is a workaround:

var temp =''


    temp += '<li><a href="#_'+ id +'" onclick="'+ funcao +'"><img src="'+ icone +'" width="32" height="32"  />'+ label +' </a></li>'
    //menu
    $('#menu_footer').append(temp)

Using on click works great, but its not optimized, and know a have another script who doesnt allowed this.

Any way to fix this??

Re: JQuery Selectors - add events to button's or other elements

Depends on what you want to do onclick. If you want to cancel the default beahvior, just "return false" in your onclick

function myHandler() {
...
    return false;
}

... onclick="return myHander()" ...

Re: JQuery Selectors - add events to button's or other elements

A Simple example:

    <script type="text/javascript" src="WebApp/Action/Logic.js"></script> 
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>
    
    <script type="text/javascript">
    $(document).ready(function(){
            
        $('.myLink').click(function(){
            
        alert('Click Alert')
        })
            
    });

    </script>
<div id="WebApp">
    <div id="iLoader"><span>Loading ...</span></div>
    <div id="iHeader">
            <a href="#" id="waBackButton" >back</a>
        <!--    <a href="#" id="waHomeButton"  >Inicio</a>-->
            <a href="#" onclick="return WA.HideBar()"><span id="waHeadTitle">Company</span></a>
    </div><!--close iHeader-->

    <!--Start app-->
    <div id="iGroup">
            <div class="iLayer" id="waHome">
                    <div class="iBlock">
                        <p><a href="#_Second">Link with no code, it works</a></p>
                    </div>
                    <div class="iBlock myContainer">
                        <p><a href="#_Second" class="myLink">Link with code, go to page but dont execute jquery function</a></p>
                    </div>
                    <div class="iBlock ">
                        <p><span class="myLink">Span with code, execute normally</span></p>
                    </div>
                    
            </div>
            
            <div class="iLayer" id="waSecond">
                    <div class="iBlock">
                        <p>Yes, you made it
                        </p>
                    </div>
            </div>
        <!--Close app-->    
           
    </div>
    
</div>
</body>

if you test, the "span" trigger the alert, but not the link "a".

Re: JQuery Selectors - add events to button's or other elements

OK. The framework use capture to handle clicks and the stop propagation when a menu link is identified. The only way to add an extra handler is to use onclick.

I'll try to think about that when working on the new version.

Re: JQuery Selectors - add events to button's or other elements

I'm hitting my head over this for months , and doing a lot of work to create onclick with jquery, but know is getting harder because the new plugins are coming less and less  obstrusive.

Let me know if you find a solution or fix, I m working in a big project and i dont want to change to Jtouch, webapp is much nicer big_smile

Re: JQuery Selectors - add events to button's or other elements

Looking at the code I really don't know why the event is not executed.

For now, you can try to add a new attribute to your <a>, something like data-behavior="link".
Then in the ListenClick() function (in WAn) just add:

/* Checkbox label */
var o = e.target;
...
if (o.getAttribute("data-behavior") == "link")
    return;

Absolutely not tested but should work

Re: JQuery Selectors - add events to button's or other elements

Hi Chrilith,

This solution didn't fit my app at all, any ideia how to fix, or where i can find a solution?

Re: JQuery Selectors - add events to button's or other elements

jQuery use a custom event scheme. Perhaps the best is not t use jQuery for events.

Did you try that ?

Re: JQuery Selectors - add events to button's or other elements

Add target="_top" to your link to fix the problem.
