jquery mobile rangeslider when it hit max value add + sign -

-

i wondering how add plus (+) sign jquery mobile range slider higher value when max value selected/hit. example on price top range, has + when max value selected.

i tried changing max value <input type="range" name="range-1b" id="range-1b" min="400" max="2000+" value="1500" step="50"> didnt work, tried change script, didnt work either. not sure if possible so. 

  <script>   $(document).on('pageshow',function(){     var value = document.getelementbyid("range-1b").value;     if(value =2000){      document.getelementbyid("range-1b").value="2000+";     }   });   </script>

when jqm enhances rangeslider, inputs set type="number". type accepts numbers, text '100+' cannot set value of input.

one workaround position '+' next 100:

in rangeslider markup, add <span> class of labelplus:

<div data-role="rangeslider">     <label for="range-1a">rangeslider:</label>     <input type="range" name="range-1a" id="range-1a" min="0" max="100" value="40" />     <label for="range-1b">rangeslider:</label>     <input type="range" name="range-1b" id="range-1b" min="0" max="100" value="80" />     <span class="labelplus">+</span> </div>

use labelplus class css hide span , absolutely position in correct spot:

.labelplus{     display: none;     position: absolute;     right: 0px;     font-size: 14px;     font-weight: bold;     text-align: right;     width: 12px;     line-height: 30px;     margin-right: 18px;     margin-top: 0px; }

in javascript, handle change event on high input , check see if @ 100. if so, show plus sign span, otherwise hide it:

$("#range-1b").on("change", function(){     var val = $(this).val();     if (parseint(val) >= 100) {         $(".labelplus").show();      } else {         $(".labelplus").hide();     } });
