[Personal summary] common skills in Asp.net Development

1. implement automatic jump of text box focus and submit the form through the Enter key < ASP: textbox ID = "Passwd" Onkeydown = "If (event. keycode = 13) {document. All. imgbtnlogin. Focus (); event. keycode = 13; event. keycode = 13; return true ;}" Runat = "Server" Borderstyle = "Ridge" Textmode = "Password" > </ ASP: textbox >

In document. All. imgbtnlogin. Focus (); imgbtnlogin is the ID of the submit button

2. Get Page focusPage. registerstartupscript ("Getfocus","<SCRIPT> document. All ('"+Textbox1.clientid+"'). Focus (); </SCRIPT>");

Textbox1 is a web control, and textbox1.clientid is used to obtain the ID of the Web Control and send it to the client.

3. Clear cookies < Script Language = " Javascript " >
Function Clearbrowsedcookie ()
{
Document. Cookie= "Yourcookies=; Expires = Fri, 25-dec-1999 08:08:08 GMT; Path =/";
Document. getelementbyid ('browsedproductlist1 _ tabbrowsedproduct'). style. Display= "None";

Function Tabshow ()
{
If (Tab1.style. Display = " None " )

Tab1.style. Display="";
}

Tab1.style. Display="None";
}
}
</ Script >

Function:

{
VaR Tabname = Document. getelementbyid (Tab );
If (Tabname. style. Display = " None " )
{
Tabname. style. Display="";
