get DOM other page

get DOM other page

    Hello people,

    I have a problem to display a dialog and try to get an element of another page already used.

    file1.html
    1. <div data-role="page" id="photo-click" class="page" style="background-color: #FFF">
    3.          
    4.       ...
    5.          <div data-role="content" data-iscroll class="iscroll-wrapper">
    6. <div class="iscroll-scroller">
    7.   
    8.     
    9.    <img id="largeImage" src="images/imagem.jpg" class="image-photo"  />
    10.    ...
    11. </div><!-- /content -->
    this is the structure of file.html, I spend an element via the id for example $ ("largeImage"), but it returns me "null"
    2. <div data-role="page" id="photo-choice" >
    3.     <div data-role="header" class="hn-wrapper ui-bar-b">
    4.         <h3 style="font-size: 11px !important">
    5.             SELECIONE A OPÇÃO
    6.         </h3>
    7.     </div><!-- /header -->
    8.     <div data-role="content">
    9.         
    10.         <div style="margin-left:-7px">
    11.             <img src="images/btn-cam.png" onclick="capturePhotoEdit();">
    12.                 <img src="images/btn-library.png" onclick="getPhoto(pictureSource.PHOTOLIBRARY);">
    13.                     </div>
    14.         
    15.     </div><!-- /content -->
    16.     
    17. </div><!-- /page -->
    this is the java script I am using ...
    2. function onPhotoURISuccess(imageURI) {
    3.     
    4.     console.log("Seleciona imagem...");
    5.     imagemClick = imageURI;
    6.     
    7.     var largeImage = document.getElementById('largeImage');
    8.     /*
    9.     largeImage.style.display = 'block';
    10.     
    11.     largeImage.width = 120;
    12.     largeImage.height = 118;
    13.     
    14.     largeImage.src = imageURI;
    15. */
    16.     console.log(imageURI);
    17.     
    18.     $( "#photo-choice").dialog('close');
    19.     
    20.     console.log('close dialog');
    21.     

    23. }
    or using document.getElementById ('largeImage'); works ...

    Can anyone help me with that?
    thank you!
