本文描述了如何使用Microsoft Word在Web页面ASP文件中添加拼写检查功能。
详细的步骤
按照下列步骤建立ASP应用程序:
1、在Web服务器所在机器上,启动Microsoft Visual Interdev 6.0,选择File/New Project。
2、在“新工程”对话框的名字编辑域中,输入“WebSpell”,然后双击新Web工程图标。
3、在接着出现的Web工程向导对话框中,输入或者选择你的Web服务器名字。将工作模式默认为Master,点击Next,再点击“finish”。
4、在Visual InterDev创建工程完成后,打开工程菜单,选择“添加Web Item/HTML页面”,命名为“CheckSpelling”,然后点击Open。
5、添加的HTML页面默认状态下以设计视图打开。在页面上拖出一个HTML文本区域,放置一个HTML提交按钮,根据你的爱好进行布局,在页面上输入一些文字,告诉用户在文本域中输入需要进行拼写检查的文字。
6、选择页面上的所有对象(CTRL+A),然后从Visual InterDev的 HTML菜单中选择Form,将对象包裹在表单中。
7、点击当前窗口底部的源码功能页面,切换到源码显示视图。修改HTML开放< FORM >标记的action属性值为results.asp。
8、打开Project菜单,选择“添加Web Item/Active Server Page”,命名为“results”,然后点击“Open”。
9、对于新页面,切换到源码视图,在<BODY>标记之间输入下面的代码:
<!-- Page header -->
<p><center><font size=+4 color=red>Spelling Results</font></center><hr>
<!-- Show user the text they entered -->
<p>The text you entered was:<p>
<font color=blue><%=Request("TEXTAREA1")%></font><p><hr><p>
<!-- Begin server-side script to check spelling errors -->
<%
' Don't allow other sessions to re-enter :)
do while(Application("WordInUse") = 1)
loop
Application("WordInUse") = 1
' Get Word references created in global.asa.
dim wdApp
set wdApp = Application("WordApp")
dim wdDoc
set wdDoc = Application("WordDoc")
' Clear current contents.
dim wdRange
set wdRange = wdApp.Selection.Range
wdRange.WholeStory
wdRange.Delete
set wdRange = Nothing
' Add the text the web user entered.
dim txt
txt = Request("TEXTAREA1")
wdApp.Selection.TypeText CStr(txt)
' Check spelling without prompting.
'wdDoc.CheckSpelling , , 0
' Get spelling errors collection.
dim wdErrors
set wdErrors = wdDoc.SpellingErrors
%>
<% ' Handle no-error condition.
if wdErrors.Count = 0 then
%>
There were no spelling errors.
<%
' Otherwise build a table of suggestions.
else
%>
<!-- Build a table to show errors & suggestions -->
<font color=red>There were <%=wdErrors.Count%> spelling error(s).</font><p>
<TABLE border=1 cellPadding=1 cellSpacing=1 width=75%>
<TR>
<TD><b><font size=+1>Word</font></b></TD>
<TD><b><font size=+1>Suggestions</font></b></TD></TR>
<%
for each wdError in wdErrors
' Write the word in question.
Response.Write("<TR><TD>")
Response.Write(wdError.Text)
Response.Write("</TD><TD>")
' Get spelling suggestions for it.
dim wdSuggestions
set wdSuggestions = wdApp.GetSpellingSuggestions(wdError.Text)
if wdSuggestions.Count <> 0 then
' a comma-separated list of suggestions.
dim strSuggestions
strSuggestions = ", "
for each wdSuggestion in wdSuggestions
strSuggestions = strSuggestions & wdSuggestion.Name & ", "
next
' Remove extra comma & space.
strSuggestions = Right(strSuggestions, len(strSuggestions)-2)
' Write out suggestions.
Response.Write(strSuggestions)
else
Response.Write("None.")
end if
set wdSuggestions = Nothing
Response.Write("</TD></TR>")
next
end if
' Release references.
set wdErrors = nothing
set wdDoc = nothing
set wdApp = nothing
' We're done, allow other sessions to continue.
Application("WordInUse") = 0
%>
10、在Visual InterDev 工程浏览窗口中,双击Global.asa文件,在< SCRIPT >标记之间添加下面2段子程序:
Sub Application_OnStart()
' Launch Word.
dim wdApp
set wdApp = CreateObject("Word.Application")
set Application("WordApp") = wdApp
' Add a document.
set Application("WordDoc") = wdApp.Documents.Add
' Release reference.
set wdApp = nothing
End Sub
Sub Application_OnEnd()
' Get Automation references.
dim wdApp
set wdApp = Application("WordApp")
dim wdDoc
set wdDoc = Application("WordDoc")
' Tell Word to shutdown.
wdDoc.Saved = true
wdApp.Quit
' Release references.
set Application("WordDoc") = Nothing
set Application("WordApp") = Nothing
set wdDoc = nothing
set wdApp = nothing
End Sub
