你怎么能从两个价格游侠那里获得多个价值

Question

我正在研究具有多个幻灯片范围的价格计算器。

我很难将结果转换为整数并将两个结果相乘。还不知道如何处理滑块的onchange功能。

请参阅我的代码：

＆＃13;

＆＃13;

  < script >
    $(function() {
      $("#slider-range-min").slider({
        range: "min",
        value: 400,
        min: 400,
        max: 2000,
        slide: function(event, ui) {
          $("#amount").val("£" + ui.value);
        }
      });
      $("#amount").val("£" + $("#slider-range-min").slider("value"));
      $('#slider-range-min').draggable();
    });

  $(function() {
    $("#slider-range-min2").slider({
      range: "min",
      value: 3,
      min: 3,
      max: 12,
      slide: function(event, ui) {
        $("#amount2").val(ui.value + " months");
      }
    });
    $("#amount2").val($("#slider-range-min2").slider("value") + " months");
    $('#slider-range-min2').draggable();
  });

  $(function() {
    x = ($("#slider-range-min").text(), 10);
    y = ($("#slider-range-min2").text(), 10);
    $("#amount3") = (x * y).text().draggable();
  });

  < /script>

Answer 1

使用parseInt将值转换为整数。 （当然，在使用它们之前，您应该检查值是否有效。

同样x和y是数字，您不能像这样使用.draggable()或将它们设置为等同于jQuery对象：

 $(function() {
    x = parseInt($("#slider-range-min").text(), 10);
    y = parseInt($("#slider-range-min2").text(), 10);
    if(!isNaN(x) && !isNaN(y))
    $("#amount3").val(x * y)).draggable();
  });
