推荐答案

我们真的相信两个用户问的是确切的吗彼此之间在几秒钟内就遇到了同样的问题?

Are we really to believe that two users asked the exact same question within seconds of each other ?

您必须进行回发，并在委托中调用方法abc().
要在javascript中进行回发，可以使用GetPostBackEventReference.

或使用

You must do a postback and in the delegate call you method abc().
For make a postback in javascript you can use GetPostBackEventReference.

Or use Ajax callbacks to Web Methods

试试这个

Hi,

try this

function doClick(e){
               //the purpose of this function is to allow the enter key to
               //point to the correct button to click.
       var key;
        if(window.event)
             key = window.event.keyCode;     //IE
        else
             key = e.which;     //firefox

           if (key == 13)
           {
               //Get the button the user wants to have clicked
               var btn = document.getElementById("ctl00_ContentPlaceHolder1_btnSearch");
               if (btn != null)
               { //If we find the button click it
                   btn.click();
                   event.keyCode = 0
               }
           }
       }
