javascript - How to handle slider change event for multiple sliders in a page: JqueryMobile -


in app have multiple pages in single html template, each of pages have 5 sliders, when move slider ,based on value(1 5) display text. below sample of 2 pages

<!-- start of 2 page-->  <div data-role="page" id="page2" >      <!-- start of content -->     <div data-role="content" id="target-content">     <label for="slider">1. .............</label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>       <label for="slider1">2............................ </label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>       <label for="slider2">3. ................</label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>      </div>     <!-- end of content -->  </div> <!-- end of 2 page-->  <!-- start of 3 page-->  <div data-role="page" id="page3" >      <!-- start of content -->     <div data-role="content" id="target-content"" >     <label for="slider">1. .............</label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>       <label for="slider1">2............................ </label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>       <label for="slider2">3. ................</label>     <input type="range" name="slider" id="slider" value="0" min="0" max="5"  />      <label id="sliderlabel"></label>      </div>     <!-- end of content -->  </div> <!-- end of 3 page-->

i doing first slider based on id below:

<script type="text/javascript">  $(document).on('pagecreate', function() {      $("#slider").change(function () {         sval = $(this).val();          if (sval == 0) {             $('#sliderlabel').text('');         }          if (sval == 1) {             $('#sliderlabel').text('strongly disagree');         }            if (sval == 2) {             $('#sliderlabel').text('disagree');         }            if (sval == 3) {             $('#sliderlabel').text('neither agree nor disagree');         }            if (sval == 4) {             $('#sliderlabel').text('agree');         }            if (sval == 5) {             $('#sliderlabel').text('strongly agree');         }         }); }); </script>

now how implement changing text each sliders of page , sliders of other pages in 1 single index.html page.

as @raymond camden mentioned in answer, use .class instead of id, id should unique.

since you're using multi-page model, need add change listener upon pagecreate event. however, have specify page in order not add multiple listener on same page (usually first page in dom). on pagecreate add change listeners .slider within $(event.target) page, way.

$(document).on("pagecreate", function (event) {    $(event.target).find(".slider").on("change", function () {       sval = $(this).val();         if (sval == 1) {           $(this).closest("div").next('.sliderlabel').text('new text');         }    }); });

$(event.target) page has been created, using .find(), attach change listener .slider.

to change label's text, need replace id .class. moreover, need use .closest() , .next() since sliders wrapped in <div class="ui-slider"> , label sibling of div.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
