Tip 1-prevent JS from caching CSS as well
<SCRIPT type = "text/JavaScript" Language = "JavaScript" src = "../JS/checksfz. js? Temp = <% = datetime. Now. ticks %> "> </SCRIPT>
******************************
Prohibit copying, cutting, and right-built

Oncontextmenu = "event. returnvalue = false" oncopy = "event. returnvalue = false"
Oncut = "event. returnvalue = false"

The text box cannot be automatically recorded.
AutoComplete = "off"
******************************
· Hyperjoin Style
******************************
A: link refers to a normal link that has not been accessed;
A: hover refers to the mouse over the link;
A: The link of active vertices;
A: visited refers to the accessed link.
 
Parameter settings:
 
Text-decoration indicates the effect of text modification; none indicates that the hyperlink text is not underlined; Underline indicates that the hyperlink text is underlined; overline indicates that the hyperlink text is underlined; line-through is used to delete the hyperlink text. Blink is used to make the text flash.
 
Color: blue, color: Red, etc. are used to add color to the link text.
 
You can also add other parameters, such:
 
Font-weight: bold to bold the link text; font-size: 16pt to set the link text font size; Background: # ffd306 to add the background color to the link text; font-style: italic link text skew; border-bottom: 1px dashed #51bfe0 adds a dotted line to the link text. 1px indicates the coarse granularity of the dotted line. The larger the value, the thicker the dashed indicates the dotted line, #51bfe0 is the dotted line color. If you want to add a dotted line to the link text, you do not need to underline it.

· Response clear
************************************

Response. expires = 0; // set the validity period
Response. Buffer = true; // use the cache Region
Response. Clear (); // clear response
Response. contenttype = "image/PNG"; // specify the output type.
Response. statuscode = 200;
Response. End ();
************************************
· Webrequest Column
************************************
Response. Clear ();

Httpwebrequest request = (httpwebrequest) webrequest. Create (@ "http://www1.fx168.com/fxindex/FMonthIndex.aspx? Datetime = 2007-10-16 "); // get a URL request
Httpwebresponse response = (httpwebresponse) request. getresponse (); // get the output stream object
Stream resstream = response. getresponsestream (); // gets the output stream
Byte [] Buf = new byte [1, 1024];
Int COUNT = 0;
While (COUNT = resstream. Read (BUF, 0, Buf. Length)> 0) // convert the stream into a byte sequence
{
Response. write (system. text. encoding. default. getstring (BUF, 0, count ). replace ("oncontextmenu =/" Return false;/"onselectstart =/" Return false;/"oncopy =/" Return false;/"oncut =/" Return false; /"", ""); // print the characters in the throttling and replace the JS script
}
Resstream. Close ();

*****************************

Window. open () attributes
****************************

Window. open (URL, 'Pop-up window 'height = 455, width = 655, Top = 50, Left = 300, toolbar = No, menubar = No, scrollbars = No, resizable = No, location = No, status = Yes, charset = UTF-8 ')

****************************

Determine the browser type window. Navigator. appname
Judge IE version window. Navigator. appversion
Determine the client's resolution window. Screen. height; window. Screen. width;

***************************
The value of all forms cannot be blank. <input onblur = "If (this. value. replace (/^/S + |/S + $/g, '') ='') Alert ('cannot be blank! ') ">

1. Email judgment.
Function Ismail (Mail)
{
Return (New Regexp (/^/W + (-/W +) | (/./W +) */@ [A-Za-z0-9] + (/. | -)
[A-Za-z0-9] +) */. [A-Za-z0-9] + $/). Test (Mail ));
}

 

2. ID card verification
Function isidcardno (Num)
{
If (isnan (Num) {alert ("the input is not a number! "); Return false ;}
VaR Len = num. length, RE;
If (LEN = 15)
Re = new Regexp (/^ (/d {6 })()? (/D {2}) (/d {2}) (/d {2}) (/d {3}) $ /);
Else if (LEN = 18)
Re = new Regexp (/^ (/d {6 })()? (/D {4}) (/d {2}) (/d {2}) (/d {3}) (/d) $ /);
Else {alert ("the number of digits entered is incorrect! "); Return false ;}
VaR A = num. Match (re );
If (! = NULL)
{
If (LEN = 15)
{
VaR d = new date ("19" + A [3] + "/" + A [4] + "/" + A [5]);
VaR B = D. getyear () = A [3] & (D. getmonth () + 1) = A [4] &
D. getdate () = A [5];
}
Else
{
VaR d = new date (A [3] + "/" + A [4] + "/" + A [5]);
VaR B = D. getfullyear () = A [3] & (D. getmonth () + 1) = A [4] &
D. getdate () = A [5];
}
If (! B) {alert ("entered ID card number" + A [0] + "contains incorrect birthdate! "); Return false ;}
}
Return true;
}

3. Determine the file type during File Upload
<Input type = file onchange = "alert (this. value. match (/^ (. *)(/.) (. {1, 8}) $/) [3]) ">

4. Continuously clear the clipboard:
<Body onload = "setinterval ('clipboarddata. setdata (/'text/',/') ', 100)">

5. File: // window. opener. Location. Reload (); refresh the parent window.
6. File: // window. opener. Location = "2.htm" // The target parent window is displayed on the 2.htm page.

7. Description: How long does it take for a webpage to refresh itself (in seconds), or how long does it take for the webpage to automatically link to another webpage.
Usage: <meta http-equiv = "refresh" content = "30">
<Meta http-equiv = "refresh" content = "5; url = http://www.xia8.net">

8. SQL calculates the number of days in a month
Select Day (dateadd (day,-1, convert (char (07), dateadd (month, 1, @ date), 120) + '-01 '))

9. url Transcoding
Src = "drawing. aspx? Ccoms = <% = server. urlencode (ccoms) %>"

10. Save the current webpage location
Smartnavigation = true --- added to the page attribute

11. custom exception classes

Public class myexception: applicationexception

 

{
Public myexception (): Base ()

{

}

/// <Param name = "errmessage"> exception message </param>

Public myexception (string message): Base (Message)
{

System. Web. httpcontext. Current. response. Redirect ("~ /Showerr. aspx? MSG = "+ message );

}

/// <Param name = "message"> exception message </param>
/// <Param name = "innerexception"> exception class that causes this exception </param>
Public myexception (string message, exception innerexception): Base (message, innerexception)
{

}

}

12. ifream auto-fit size
Onload = "This. Height = document.frames%02.16.doc ument. Body. scrollheight"
