Form集合是用来获取表单中form元素的值的。这些form元素是用户通过POST方式发送的。

注意:如果你要传输的是大容量数据(如:大于100kb),那么就不能使用Request.Form命令。

Example 1 You can loop through all the values in a form request. If a user filled out a form by specifying two values - Blue and Green - for the color element, you could retrieve those values like this: <% for i=1 to Request.Form("color").Count Response.Write(Request.Form("color")(i) & "<br />") next %> Output: Blue Green Example 2 Consider the following form: <form action="submit.asp" method="post"> <p>First name: <input name="firstname"></p> <p>Last name: <input name="lastname"></p> <p>Your favorite color: <select name="color"> <option>Blue</option> <option>Green</option> <option>Red</option> <option>Yellow</option> <option>Pink</option> </select> </p> <p><input type="submit"></p> </form> The following request might be sent: firstname=John&lastname=Dove&color=Red Now we can use the information from the form in a script: Hi, <%=Request.Form("firstname")%>. Your favorite color is <%=Request.Form("color")%>. Output: Hi, John. Your favorite color is Red. If you do not specify any element to display, like this: Form data is: <%=Request.Form%> the output would look like this: Form data is: firstname=John&lastname=Dove&color=Red |
