如何在OnClientDragEnd事件MultiHandleSliderExtender上调用c#函数而无需回发 [英] How to call a c# function on OnClientDragEnd event MultiHandleSliderExtender without postback

问题描述

大家好

我正在使用MultiHandleSliderExtender使用Java脚本函数按价格对其产品进行过滤

Hello all

i am using MultiHandleSliderExtender for filtering the product by their price for that am using a java script function

<script type="text/javascript">

    function ValueChangedHandler(sender, args) {

       __doPostBack("Button1", "Click");
        <%SetData(); %>
    }

    </script>

用于调用c#方法，但我确定了回发，如何在不对MultiHandleSliderExtender的OnClientDragEnd执行回发的情况下调用此方法.

请帮助..

推荐答案

您要通过Javascript与服务器进行交互.
通过客户端(Javascript)与服务器端进行交互的方法很少:
1. XMLHttpRequest [回调 [ Web服务调用 [ PageMethod [ http://api.jquery.com/jQuery.ajax/ [ http://www.w3schools.com/jquery/jquery_ref_ajax.asp [

You want to interact with server from Javascript.
There are few ways to interact with server side through client side(Javascript):
1. XMLHttpRequest[^]
2. Callback[^]
3. WebService call[^]
4. PageMethod[^]

If you know jQuery, you can use it''s ajax method:
http://api.jquery.com/jQuery.ajax/[^]
http://www.w3schools.com/jquery/jquery_ref_ajax.asp[^]
