Question

我想咨询有关javascript jquery的问题我希望这个值> 20 && <40清除或重置jquery建议中的选项。它在javascript中出现函数错误，并且没有no clear and reset选项。但是功能显示显示块位置错误。

$scope.addPersonnelsByRole = function(addObj, user_role_type_id, formName) {
  if ($scope.addPersonnelValidation(formName)) {
    //valid form
  }
}

<script>
function Checkbox() {
    var length = document.tester.selection.length;
    var $result = "";
    var chked = 0;
    for (i = 0; i < length; i++) {
       if (document.tester.selection[i].checked) {
          $result += document.tester.selection[i].value;
       }
    }
    var getdata = $result;

}

var checked, checkedValues = new Array();
$("input[type=checkbox]").change(function(e) {
    var selectedtext = ($(this).next().text());
    if ($(this).is(':checked')) {
       $("#showdatacheckbox").append('<option value="' + selectedtext + '">' + selectedtext + '</option>');
    } else {
       $('option[value*="' + selectedtext + '"]').remove();
    }

});

function range(val) {
    document.getElementById('number').value = val;
}
prefer = document.getElementById("number").value;
if (prefer > 20 && prefer < 40) {
    document.getElementById("wordingprogrammer").style.display = "none";
    document.getElementById("wordingsenior").style.display = "none";
} else {
    document.getElementById("wordingprogrammer").style.display = "block";
    document.getElementById("wordingsenior").style.display = "block";
}
		
</script>
