jQuery Forum

You really need to stop and post a clear question. You should start with posting your code. Then you need to clearly state your question. When you say things like "it disappears", I have no idea what you mean. Then you can move on to an example, perhaps created on jsfiddle.net.

You need to read the documentation for jQuery Mobile. Begin at the beginning.

This is not going to work for you in JQM:

$(document).ready(function(){

Big yellow box, top of the page:

http://jquerymobile.com/demos/1.1.1/docs/api/events.html

Also, it's not advisable to use IDs with JQM, because they could be duplicated across pages. Becuase JQM loads multiple pages into the same document, then an ID could be duplicated in the document, and that is not allowed in HTML, with inconsistent results across browsers. Use classes instead.

I suggest you at least read most of the Pages and Dialogs section of the documentation.

You can certainly update any part of a page. There actually is no functionality in jQuery Mobile for this, so that's why you aren't finding anything.

You can use jQuery functions to update parts of a page. There are many jQuery functions that can be used to update elements, so I'm not going to give an exhaustive list here. Look at the jQuery documentation.

If you insert new content that contains jQuery Mobile widgets, then you need to call .trigger("create") on the parent. If you change something inside of certain widgets (for example, a listview) then you need to call .refresh() on the listview, etc. instead. This you will find in the jQuery Mobile documentation. (If you look hard enough! Unfortunately, the docs aren't very developer-friendly, and aren't searchable except with Google and other search engines.)
