Multiple instances of Pageinit are triggered

Currently, I am working on developing a jQuery Mobile and PhoneGap application. Here is an excerpt of the code I am using:

$('#contact').live('pageinit', function() {
    //$.mobile.loading('show');
    theme();
    getData('contact/list', contactList);
    //$.mobile.loading('hide');
});

Everything seems to work fine when accessing the page for the first time. However, upon subsequent attempts, the event starts firing multiple times. I have attempted using bind but it did not resolve the issue.

I suspect this behavior is related to the live event being bound each time the page is initialized, leading to multiple firings. I found that linking through window.location.href resolves the problem as it recreates the DOM, although unfortunately, this solution is not feasible in my case.

Is there an alternative approach to handling the pageinit event?

I have tried searching for a solution without success thus far. I also came across a similar issue discussed on: click() firing multiple times.

Answer №1

According to the concept, any event that is capable of being linked with 'live' can also be directly linked. The advantage of direct linking is that it will effectively replace the previous linked handler. This means you would only have a single handler, preventing multiple triggers upon subsequent loading.

You could consider using something along these lines:

$("#info").initializePage(function() {
  customizeTheme();
  retrieveData('info/list', informationList);
});

Answer №2

Instead of using the outdated live() method, I prefer to utilize the on() method. Each of my page containers is assigned a unique id, for example, on the index page it could be named index. This allows me to easily bind events like so:

$(document).on("pageinit", "#index", function() {
    //perform actions here
});

This approach also works similarly for handling page show events.

Answer №3

When working with jQuery Mobile and binding events, it is crucial to be cautious in order to avoid multiple bindings. Unlike traditional navigation where events may be reset when navigating to a new page, jQuery Mobile does not automatically reset bound events. The problem you are encountering is likely caused by the function being bound to the event every time the page is accessed, resulting in the function being executed multiple times. To ensure that the event is only bound once, I recommend binding it in the header of your initial page. This will ensure that the event is bound just once and the function will run whenever the page is initialized.

Answer №4

If you are experiencing issues with events firing multiple times on your webpage, consider including data-ajax="false" in the forms that could be generating these duplicates.
