VBScript可以正常运行,转换成JavaScript却不行?

程序的目的是调用OCX控件打印条形码.如果使用VBScript就可以达到需要的效果,但是相应的代码转化成JavaScript却不行.VBScript页面代码:<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

解决方案 »

  1.   

    尝试一下改成document.all("UserCode391")试试吧，javascript太高深-0-常常伴有人品问题-0-
      

  2.   

    把JAVASCRIPT脚本放到<head>里，通过getElementById（）取得元素：
    <%@ page language="java" contentType="text/html;charset=GB2312"%><html> <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
    <meta name="ProgId" content="FrontPage.Editor.Document">
    <title>JAVA条码打印测试</title> <script type="text/javascript">
       function Print()
             {
              //定义
               var uCode391= document.getElementById("UserCode391");
                //alert("打印按钮被单击！");
                var i= 0;
                i = uCode391.sReady();
                if (i==0 ) 
                {
                  alert("打印机未准备好！");
                } 
                else 
                {
                  //alert("打印机已准备好！"+ i);
                  uCode391.NewDoc();
                  uCode391.AddTxt("1001001-0014268");
                  uCode391.PrintDoc("LPT1",1);
                  uCode391.NewDoc();
                  uCode391.AddTxt("1001001-0010002");
                  uCode391.PrintDoc("LPT1",1);
                  uCode391.GetClosePort();  
                }
             }</script>
    </head> <body> <p>
    <object classid="clsid:7D617E59-1F32-4830-999D-094CA7C5F933"
    id="UserCode391" width="40" height="35">
    <param name="_ExtentX" value="873">
    <param name="_ExtentY" value="873">
    </object>
    </p> <FORM NAME="Form1">
    <INPUT TYPE="Button" NAME="Button1" VALUE="打印" onClick="Print()">
    </FORM>
    </body></html>
      

  3.   

    建议用 getElementById（）
    document.all只有ie和ie内核的支持你可以用 alert(document.getElementById("你对象的名"))看看对象是不是为空了 如果不为空 打印出来的好象是 [object] 如果我要没记错的话.
