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>
