ajax 滑块和 Javascript

Question

重写以使事情变得简单并让我理解我需要的...

我想知道如何更新 Ajax 控制工具包最大值以及如何获取其中一个滑块的当前值。这一切都应该在客户端完成。

想法是这样的：

int Used      = 0
int max       = 325
int Remainder = max - Used

slider1.maximum = Remainder
slider2.maximum = Remainder
slider3.maximum = Remainder

slider1.value = 0
slider2.value = 0
slider3.value = 0

slider1.Setvalue = 150
   Used = 150
   Remainder = 175
   slider1.maximum = Remainder   + slider1.value 
            Becoming 175         + 150
   Slider2.maximum = Remainder   + slider2.value
            Becoming 175         + 0
   Slider3.maximum = Remainder   + slider3.value
            Becoming 175         + 0

slider2.Setvalue = 50
   Used = 200
   Remainder = 125
   slider1.maximum = Remainder   + slider1.value 
            Becoming 125         + 150
   Slider2.maximum = Remainder   + slider2.value
            Becoming 125         + 50
   Slider3.maximum = Remainder   + slider3.value
            Becoming 125         + 0

slider3.Setvalue = 125
   Used = 325
   Remainder = 0
   slider1.maximum = Remainder   + slider1.value 
            Becoming 0           + 150
   Slider2.maximum = Remainder   + slider2.value
            Becoming 0           + 50
   Slider3.maximum = Remainder   + slider3.value
            Becoming 0           + 125         

Slider1.Setvalue = 125
   Used = 300
   Remainder = 25
   slider1.maximum = Remainder   + slider1.value 
            Becoming 25          + 125
   Slider2.maximum = Remainder   + slider2.value
            Becoming 25          + 50
   Slider3.maximum = Remainder   + slider3.value
            Becoming 25          + 125  

我认为这不会变得更清晰，所以请给我一些反馈。非常感谢！

一旦用户对设置感到满意，就应该通过按钮将其发送回服务器。

我知道这是一个老问题，但由于没有人回答，而且这是我查看的第一页（谷歌搜索同一问题），我想我应该放弃在这里找到的答案。也许它会缩短其他人的搜索时间。

假设您要扩展的文本框名为 Slider1。您可以使用 $find() 设置滑块的值和最大值。即：

$find("Slider1").set_Maximum(100);
$find("Slider1").set_Value(500);

您可以从绑定文本框中获取滑块的值，就像从任何其他元素获取滑块的值一样。所以：

var sliderValue = document.getElementById('<%=Slider1_bound.ClientID%>').value;
