从后面的C＃code调用JS功能 [英] Call JS function from code behind C#

问题描述

我有一个功能叫做onRowClick和RowClick工作正常。我想将它移动到一个按钮，后面调用从code的作用。出于某种原因，无法触发功能..任何人都知道为什么，我该如何解决这一问题？

aspx.cs

 如果（e.CommandName ==Addvoucher）
            {               GridDataItem项目=（GridDataItem）e.Item;            变种的id = item.GetDataKeyValue（的RowID）;            ClientScript.RegisterStartupScript（Page.GetType（），的myKey，RowClick（+ ID +）;，真）;            }
 

ASPX

 ＆LT;脚本＆GT;
        VAR popUpObj;
        功能RowClick（发件人，EventArgs）{
            VAR filterId = eventArgs.getDataKeyValue（'ROWID'）;
            popUpObj = window.open（voucher.aspx？参数=+ filterId +
             ModalPopUp
             工具栏=没有，+
             滚动条=没有，+
             位置=没有，+
             状态栏=没有，+
             菜单栏=没有，+
             调整大小= 0，+
             宽度= 530，+
             高度= 500，+
             左= 450，+
             顶= 130
            ）;
             popUpObj.focus（）;
             LoadModalDiv（）;
         }
     功能LoadModalDiv（）
     {
         变种bcgDiv =的document.getElementById（divBackground）;
         bcgDiv.style.display =块;
     }     功能HideModalDiv（）{
         变种bcgDiv =的document.getElementById（divBackground）;
         bcgDiv.style.display =无;
     }     ＆LT; / SCRIPT＆GT;
 

在页面voucher.aspx

 ＆LT;脚本类型=文/ JavaScript的＆GT;             功能的OnClose（）{                 如果（window.opener = NULL＆放大器;！＆安培;！window.opener.closed）{
                     window.opener.location.reload（）; //刷新父时，弹出近
                     // window.opener.HideModalDiv（）;
                 }                 //如果（window.closed ==真）window.open（〜/ routedoc.aspx）;
             }
             window.onunload =的OnClose;    ＆LT; / SCRIPT＆GT;
 

解决方案

更改您的js函数像这样

 函数RowClick（filterId）{popUpObj = window.open（voucher.aspx？参数=+ filterId +
         ModalPopUp
         工具栏=没有，+
         滚动条=没有，+
         位置=没有，+
         状态栏=没有，+
         菜单栏=没有，+
         调整大小= 0，+
         宽度= 530，+
         高度= 500，+
         左= 450，+
         顶= 130
        ）;
         popUpObj.focus（）;
         LoadModalDiv（）;
     }
 

有没有必要这个系列现在 VAR filterId = eventArgs.getDataKeyValue（'的RowID'）的; 现在你可以直接使用参数 filterId 在js函数。

I have a function onRowClick called RowClick and is working fine. I am trying to move it to a button and call the function from the code behind. For some reason is not triggering the function.. Anyone knows why and how I can fix this?

aspx.cs

  if (e.CommandName == "Addvoucher")
            {

               GridDataItem item = (GridDataItem)e.Item;

            var id = item.GetDataKeyValue("RowID");

            ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "RowClick("+id+");", true);

            }

aspx

  <script>
        var popUpObj;
        function RowClick(sender, eventArgs) {
            var filterId = eventArgs.getDataKeyValue('RowID');


            popUpObj = window.open("voucher.aspx?param=" + filterId + "",
             "ModalPopUp",
             "toolbar=no," +
             "scrollbars=no," +
             "location=no," +
             "statusbar=no," +
             "menubar=no," +
             "resizable=0," +
             "width=530," +
             "height=500," +
             "left = 450," +
             "top=130" 
            );
             popUpObj.focus();
             LoadModalDiv();


         }


     function LoadModalDiv()
     {
         var bcgDiv = document.getElementById("divBackground");
         bcgDiv.style.display="block";
     }

     function HideModalDiv() {
         var bcgDiv = document.getElementById("divBackground");
         bcgDiv.style.display = "none";
     }

     </script>

IN page voucher.aspx

 <script type = "text/javascript">

             function OnClose() {

                 if (window.opener != null && !window.opener.closed) {
                     window.opener.location.reload(); //refreshing parent when popup close
                     // window.opener.HideModalDiv();
                 }

                 //if (window.closed==true) window.open("~/routedoc.aspx");
             }
             window.onunload = OnClose;

    </script>

解决方案

Change your js function like this

function RowClick(filterId) {

popUpObj = window.open("voucher.aspx?param=" + filterId + "",
         "ModalPopUp",
         "toolbar=no," +
         "scrollbars=no," +
         "location=no," +
         "statusbar=no," +
         "menubar=no," +
         "resizable=0," +
         "width=530," +
         "height=500," +
         "left = 450," +
         "top=130" 
        );
         popUpObj.focus();
         LoadModalDiv();


     }

There is no need of this line now var filterId = eventArgs.getDataKeyValue('RowID'); Now you can directly use the parameter filterId in your js function.
