你可以在jquery的帮助下简单地叫你web服务。以下是您的样本系数。

you can simply call you web service with the help of jquery. Here is the sample coe for you.

<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script type="text/javascript">



    function abc()
    {

.ajax（{
类型：POST，
contentType：应用/ JSON; charset = utf-8，
url：Webmethod.aspx / BindDataToDropDown，
data：{}，
dataType：Json，
success：function（数据）{
//当你成功执行web方法时调用这个函数。
//编写从web方法返回的绑定数据的代码。

}）
}
}）;
}
< / script >

.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "Webmethod.aspx/BindDataToDropDown", data: "{}", dataType: "Json", success: function (data) { // this function is called when you web method executed sucessfully. // write code for binding data returned from web method. }) } }); } </script>

只需调用函数abc（）在鼠标悬停事件的控件上它将调用Web服务。

Just simply call the function "abc()" on mouse hover event of the control it will the call the web service.

<img onmouseover="abc()" border="0" src="smiley.gif" alt="Smiley" width="32" height="32">
