            var label = DYMO.Label.Framework.Label.Open("MyText.label");
            label.SetObjectText("NameTxt", "John Smith");

            alert(" Testing 2");   // Here this alert also not working .
            label.print("DYMO LabelWriter 310");
            }
     </script>

    </head>
    <body onload="OnLoad()">
         <form action="" method="post" id="DYMOLabel">
        <center>
        <h2>DYMO Label  Example</h2>
         <input type=button value="Get DYMO Printers" onClick="GetDYMOPrinters()">
     </center>
    </form>




    </body>
</html>

但是这里什么都不会发生，我需要导入或包含任何东西吗？请给一些建议..

您<script>用于嵌入“DYMO.Label.Framework.latest.js”的 -Tag 位于另一个脚本标签内。将其移出，您的函数应该运行：
