推荐答案

// to register the ASP.NET server control
Page.GetPostBackEventReference(txtBox1);

//event to fire the TextChanged event of txtBox1
__doPostBack("txtBox1", "TextChanged");

// JavaScript function to handle the situation when the user just wanted to type
function DoPostBack()
{
   __doPostBack("txtBox1", "TextChanged");
}

//function on the OnChange event
if(!IsPostback)
{
    /...Implementation.../
    txtBox1.Attributes.Add("OnChange", "javascript:return DoPostBack()")
}
