Question

I need the variable “value” in my slider plugin to be the integer value of a input in the form:

$(function () {
  $("#calcSlider").slider({ 
    min: 0,
    max: 90,
    step: 5,
    value: /* ACCESS HERE!!!!!! */,
    slide: function (event, ui) {
      $("#calcSup").val(ui.value);
    }
  });
});

I need value: to be the value in calcSup or ${form.calcSup}, but that is a string. I need it parsed to a int:

<input type="text" 
       id="calcSup" 
       name="calcSup" 
       value="${form.calcSup}" 
       size="3" 
       readonly="readonly" />

Maybe you are looking for the parseInt function, more details can be found here:

$(function () {
$("#calcSlider").slider({ min: 0,
                          max: 90,
                          step: 5,
                          value: parseInt($('input#calcSup').val()),
                          slide: function (event, ui) {
                              $("#calcSup").val(ui.value);
                          }
                       });
                    });

<input type="text" id="calcSup" name="calcSup" value="${form.calcSup}" size="3" readonly="readonly"/>
