从外部调用jQuery中定义的函数

问题描述

我的aspx页面： -

My aspx page:-

  <script src="js/jquery-1.4.2.js" type="text/javascript"></script>
  <script src="js/jquery-ui-1.8.2.custom.js" type="text/javascript"></script>

  <script type="text/javascript">
    $(document).ready(function () {
      //lots of other code here....
      function showMessage(){
        $("#msgDiv").dialog({
                        modal: true,
                        buttons: {
                                  Ok: function() {
                                          $(this).dialog('close');
                                      }
                        },
                        resizable: true,
                        show: "explode",
                        position: "center",
                        closeOnEscape: true,
                        draggable: false
                      });
      }
    });
   </script>

从上面的页面触发的另一个aspx弹出页面

Another aspx pop up page which is triggered from the above page

<script type="text/javascript">

    window.opener.document.getElementById("msgDiv").innerHTML = <%=MessageToShow%>; //works very well for me.
    window.opener.document.showMessage(); // I am unable to access it like this?
    window.close();

</script>

基本上我想打电话给 showMessage（）从弹出窗口。我还有其他逻辑可以在两个页面中执行。

Basically I want to call showMessage() from the pop up window. I also have other logics to perform in both pages.

推荐答案

据我所知，你想做什么，可以'完成。那么，我们究竟能做些什么呢？

As far as I know, what you want to do, can't be done. So, what exactly can we do?

我认为最简单的想法就是将 showMessage 移到 ready 函数，只需从内部调用它。

I think the simpliest think would be to move showMessage outside of the ready function, and just call it from within.

现在，如果它必须在该函数中定义，请make它是一个命名函数：

Now, if it really must be defined within that function, make it a named function:

  function calledonready()
  {
      /// stuff
      function showMessage(){
      /// stuff
      }
   }

$(document).ready(calledonready);

window.opener.document.calledonready.showMessage();
