How Can I Change the range of a range slider when I select an input radio or other?

Question

I have a question and I hope you can help me with this:

  function GetGradeTemp () { var grades = $( "input[name='radios']:checked" ).val(); $( ".c_f" ).text(grades); var value1 = $("#tempMin").val(); var value2 = $("#tempMax").val(); $( "#minT" ).text(value1); $( "#maxT" ).text(value2); } $("input[name='radios']").change( GetGradeTemp ); $("#tempMin").change( GetGradeTemp ); $("#tempMax").change( GetGradeTemp ); GetGradeTemp(); $("#radio1").click( function() { // }); $("#radio2").click( function() { // });

in the code above I have two input type radio and two input type number. With the inputs type radio I can select the degree of temperature: °C or °F. In the input type number I can enter the temperature min and max. I would like to do convert the values from °C to °F or from °F to °C by clicking on the input radio options. Example: If I have the temperature in °C and I do a click on the input radio with value=F, the values of temperature must change in the input type numbers... Do you know how Can I do that with JS/jquery ?

Note: C = (F - 32) * 5 / 9 (Celsius)

F = ((C * 9) / 5 ) + 32 (Fahrenheit)

Answer 1

you only need one change() for both radio .. like so

$('[name="radios"]').on('change',function() {
  // get this value for c or f
  var ThisVal = $(this).val().toLowerCase();
  // inputs val
  var value1 = $("#tempMin").val();
  var value2 = $("#tempMax").val();
  if(ThisVal == 'c'){
    $("#tempMin").val((value1 - 32) * 5 / 9);
    $("#tempMax").val((value2 - 32) * 5 / 9);
  }else{
    $("#tempMin").val(((value1 * 9) / 5 ) + 32);
    $("#tempMax").val(((value2 * 9) / 5 ) + 32);
  }
  GetGradeTemp ();
});

See the working code

 function GetGradeTemp () { var grades = $( "input[name='radios']:checked" ).val(); $( ".c_f" ).text(grades); var value1 = $("#tempMin").val(); var value2 = $("#tempMax").val(); $( "#minT" ).text(value1); $( "#maxT" ).text(value2); } $("input[name='radios']").change( GetGradeTemp ); $("#tempMin").change( GetGradeTemp ); $("#tempMax").change( GetGradeTemp ); GetGradeTemp(); $('[name="radios"]').on('change',function() { // get this value for c or f var ThisVal = $(this).val().toLowerCase(); // inputs val var value1 = $("#tempMin").val(); var value2 = $("#tempMax").val(); if(ThisVal == 'c'){ $("#tempMin").val((value1 - 32) * 5 / 9); $("#tempMax").val((value2 - 32) * 5 / 9); }else{ $("#tempMin").val(((value1 * 9) / 5 ) + 32); $("#tempMax").val(((value2 * 9) / 5 ) + 32); } GetGradeTemp(); });
