JQM (jQueryMobile) Push last page out of DOM on changePage()

Question

I notice that the page that I was just viewing is still in the DOM. Is there a way to remove the last page viewed after I transition to the new page using changePage()?

I have disabled all the back navigation as I don't want the use to go back to the last page when transitioning to the new page(s).

Any suggestions?

Flow of the site:

• main page-> fill out info->submit on changePage()
• next page-> fill out more info-> submit on changePage()
• etc...

Once the page has been submitted I don't need it anymore

UPDATE:

Here is the first page:

<div data-role="page" 
     id="first_page" 
     data-theme="z" 
     data-backbtn="false" 
     data-url="first_page" 
     class="ui-page 
     ui-body-z">

It appends something to this when adding a new page:

<div data-role="page" 
     id="next_page" 
     name="next_page" 
     data-theme="z" 
     data-title="next_page" 
     data-url="getNextPage.php?page=next_page" 
     class="ui-page 
     ui-body-z">

Calling the live() like this:

// pageName[index] = next_page
$('#'+pageName[index]).live('pagecreate',function(event, ui){   
    $(ui.prevPage).remove();

using changePage() like this:

$.mobile.changePage('getNextPage.php?page='+pageName[index],'slide',false,false);

Solution

Not exactly knowing your markup I am guessing you are triggering changePage() manually. If that is the case, you could wire up one of the events listed here.

pageshow
Triggered on the page being shown, after its transition completes.

$('div').live('pageshow',function(event, ui){
  $(ui.prevPage).remove();
});

Example on jsfiddle.

yep that's what I'm doing now. What is the trash part?

updated my question w/ code example, but implementation of your suggests works in the demo but not my project. Would I pass the prevPage id/name to the remove()?

Instead of registering the .live() against an #id, try placing the .live() against any div that is data-role="page" $('div[data-role="page"]').live('pageshow',..., and try the pageshow instead of pagecreate

Hmm that does work in removing the prevPage but pageShow breaks my page functionality as I'm adding custom validation/page rendering of elements before the page is shown. What I'm doing is loading each page from an ajax call so only one page is in memory

[Mark Coleman]

hmmm since you have an array of ids, maybe in your pagecreate simply do $('#'+pageName[index]).remove()?

[Phill Pafford]

that works to remove the prevPage but now the current page doesn't load as it's using pagecreate() instead of pageshow, ugh.....

[Phill Pafford]

After some more testing I found the in the method you offer that ann dialogs will trigger this event as well, remove needed code for functioning pages

I wish that I could upvote this twice. Thanks a billion!
