将值从Javascript传递到ASP.net控件

问题描述：

我有一个

Hi,

I have a Javascript that I called using the the

ScriptManager.RegisterClientScriptBlock

调用的Javascript.该脚本将生成一个弹出窗口，我可以在其中浏览文件的路径.当我单击确定"按钮时，它将调用JS函数:

. The script will generate a Pop-up window where i can browse for the path of the file. When I click the OK button it will call a JS function:

function SelectAndClose() {
            txtValue = document.getElementById('_browseTextBox');

            window.returnValue = txtValue.value;
            window.close();
            return false;
        }

我对如何将txtValue变量传递到上一页并使用该值显示在文本框中感到非常困惑.非常感谢您的帮助.

谢谢！

I am quite confused on how I can pass the txtValue variable to the previous page and use the value to display in a textbox..any help is greatly appreciated.

Thanks!

以这种方式重写函数

Rewrite your function this way

function SelectAndClose() {
            txtValue = document.getElementById('_browseTextBox');
        if ((window.opener != null) && (window.opener && !window.opener.closed)) {
               window.opener.InvokeParent(txtValue.value);
        }
            window.close();
            return false;
        }

现在在父页面.aspx的脚本块中编写以下函数

Now Write Following Function in script block of .aspx of Parent Page

<script type="text/javascript">
    function InvokeParent(varValue){
      if(varValue != ""){
        // Write Required Statements to perform whatever operation
       }
    }
</script>
