Question

我有3rd party应用程序（已编译），可以从HTML页面读取数据。这是通过创建Internet Explorer对象并加载一个空白页来完成的（.navigate“ about：blank”）。表单元素通过Document.Body.innerHTML添加到页面中。通过“提交”退出HTML页面时，应用程序将通过CreateObject（“ WScript.Shell”）读取提交数据。我想添加一些JavaScript以将输入数据组合到一个字符串中。即，输入到输入文本框1和输入文本框2的数据在文本框3中合并在一起，或/和基于复选框或单选按钮更改文本框3中的值。然后，我可以将这些值发送回应用程序。如何进一步修改此空白网页以包含Java脚本来完成上述操作

“ g_objIE.Document.Body.innerHTML =”代码可以正常工作。这是非常基本的，仅包含表单元素。我可以简单地将Java脚本添加到innerHTML吗？我不这么认为。我尝试添加非常基本的代码，并收到“预期语句结尾”错误。我试图插入： “

”＆_“ document.getElementById（” demo“）。innerHTML = 5 + 6;”＆_

这是工作代码。

' First step, set up the dialog (InternetExplorer)
Set g_objIE = CreateObject("InternetExplorer.Application")
g_objIE.Offline = True
g_objIE.navigate "about:blank"
g_objIE.document.focus()

' Wait for the navigation to the "blank" web page to complete
Do
    crt.Sleep 900
Loop While g_objIE.Busy

g_objIE.Document.body.Style.FontFamily = "Sans-Serif"

' Here's where we "create" the elements of our dialog box.  We basically
' throw HTML into the document, and IE loads it in real-time for us.
' 
' The hidden "ButtonHandler" input is used to tie IE and
' SecureCRT together such that SecureCRT can know when a
' button is pressed, etc.

g_objIE.Document.Body.innerHTML = _
  "<input type=radio name='LogMode' value='Append' AccessKey='A' checked>fpeth.3125 / Access" & _
    "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp&nbsp;&nbsp;" & _
        "<input type=radio name='LogMode' value='Overwrite' Accesskey='w' >fpeth.3070 / Core<br>" & _
    "<hr>" & _
    "<b>Path/File</b>&nbsp;&nbsp;<input name='fName' size='60' maxlength='60' tabindex=1><br>" & _
    "<b>HOST</b> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input name='tID' size='30' maxlength='30'><br>" & _

    "<hr>" & _
    "<button name='Cancel' AccessKey='C' onclick=document.all('ButtonHandler').value='Cancel';><u>C</u>ancel</button>" & _
    "<input name='ButtonHandler' type='hidden' value='Nothing Clicked Yet'>"

g_objIE.MenuBar = False
g_objIE.StatusBar = True
g_objIE.AddressBar = False
g_objIE.Toolbar = False
g_objIE.height = 270
g_objIE.width = 510   
g_objIE.document.Title = "TCP"
g_objIE.Visible = True

您将要控制文档的HTML标头和doctype，这意味着您需要使用document.write而不是body.innerHTML。除了使脚本有效之外，还可以控制HTML标头和doctype。
要使事情更易于维护，请使用变量保存HTML字符串

Dim htmlString
htmlString = _
  "<!doctype html>" & _
  "<html>" & _
  "<head><title>tcp</title></head>" & _
  "<body>" & _
  "<input type=radio name='LogMode' value='Append' AccessKey='A' checked>fpeth.3125 / Access" & _
    "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp&nbsp;&nbsp;" & _
        "<input type=radio name='LogMode' value='Overwrite' Accesskey='w' >fpeth.3070 / Core<br>" & _
    "<hr>" & _
    "<b>Path/File</b>&nbsp;&nbsp;<input name='fName' size='60' maxlength='60' tabindex=1><br>" & _
    "<b>HOST</b> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input name='tID' size='30' maxlength='30'><br>" & _
    "<hr>" & _
    "<button name='Cancel' AccessKey='C' onclick=document.all('ButtonHandler').value='Cancel';><u>C</u>ancel</button>" & _
    "<input name='ButtonHandler' type='hidden' value='Nothing Clicked Yet'>" & _
    "<div id=demo>goes here</div>" & _
    "<script> " & _
    "   document.getElementById('demo').innerHTML = (5 + 6).toString(); " & _
    "</script>" & _
    "</body>" & _
    "</html>"

g_objIE.document.write(htmlString)
