Asp.net中的页面跳转及post数据

 1 /// <summary>
 2 /// This method prepares an Html form which holds all data
 3 /// in hidden field in the addetion to form submitting script.
 4 /// </summary>
 5 /// <param name="url">The destination Url to which the post and redirection
 6 /// will occur, the Url can be in the same App or ouside the App.</param>
 7 /// <param name="data">A collection of data that
 8 /// will be posted to the destination Url.</param>
 9 /// <returns>Returns a string representation of the Posting form.</returns>

12 private static String PreparePOSTForm(string url, NameValueCollection data)
13 {
14     //Set a name for the form
15     string formID = "PostForm";
16     //Build the form using the specified data to be posted.
17     StringBuilder strForm = new StringBuilder();
18     strForm.Append("<form id="" + formID + "" name="" + 
19                    formID + "" action="" + url +

21  
22     foreach (string key in data)
23     {
24         strForm.Append("<input type="hidden" name="" + key + 
25                        "" value="" + data[key] + "">");
26     }
27  
28     strForm.Append("</form>");
29     //Build the JavaScript which will do the Posting operation.
30     StringBuilder strScript = new StringBuilder();
31     strScript.Append("<script language="'javascript'">");
32     strScript.Append("var v" + formID + " = document." + 
33                      formID + ";");
34     strScript.Append("v" + formID + ".submit();");
35     strScript.Append("</script>");
36     //Return the form and the script concatenated.

对于每一个想提交的数据，我们创建了一个隐藏域来保存它的值，我们添加了必要的脚本，通过 vPostForm.submit() 来使表单完成自动提交操作。

 1 /// <summary>
 2 /// POST data and Redirect to the specified url using the specified page.
 3 /// </summary>
 4 /// <param name="page">The page which will be the referrer page.</param>
 5 /// <param name="destinationUrl">The destination Url to which
 6 /// the post and redirection is occuring.</param>
 7 /// <param name="data">The data should be posted.</param>
 8 /// <Author>Samer Abu Rabie</Author>

10 public static void RedirectAndPOST(Page page, string destinationUrl, 
11                                    NameValueCollection data)
12 {
13 //Prepare the Posting form
14 string strForm = PreparePOSTForm(destinationUrl, data);
15 //Add a literal control the specified page holding 
16 //the Post Form, this is to submit the Posting form with the request.
17 page.Controls.Add(new LiteralControl(strForm));
18 }

1 NameValueCollection data = new NameValueCollection();
2 data.Add("v1", "val1");
3 data.Add("v2", "val2");
4 HttpHelper.RedirectAndPOST(this.Page, "http://DestUrl/Default.aspx", data);

同样的这种思路还可以在js中运用
