Confirm function
The Confirm function provides a confirmation function that first displays the information contained in the given message parameter and provides two selectable answers to "OK" and "Cancel", and then waits for the user to select one of them. Returns true if the user selects "OK", otherwise false if "Cancel" is selected. The syntax format for this function is as follows:
Window.confirm (message, OK, cancel)
It has 3 parameters, in which the parameter message is a message to be displayed as a string, and the parameter OK is also used to display a string of information, which can be "OK", or other text information indicating the meaning of OK, such as "I Agree", "I like" and so on; The argument Cancel is also used to display the string information, either "Cancel" text or other textual information that represents the cancel meaning.
<script> var bln = window.confirm ("OK?"); Alert (bln) </script>
or Button.Attributes.Add ("onclick", "Javascript:if" (!confirm (' Are you sure you want to remove the system consulting? ') {return false;} ")
BUTTON.ATTRIBUTES.ADD ("onclick", "Javascript:return confirm (' Please run after landing, is it now re-login?") ‘)")
For example: <a onclick= "Javascript:if (" Are you sure you want to delete the selected information? "). \ n This operation cannot be restored! ') {return false;} " href= "Delhtml.asp?adid=<%=rs (" Adid ")%>&type_oneid=<%=rs (" Type_oneid ")%>" ><font color= " Green > Delete </font></a>
Example:
The following are placed in
<script>
function Rusure ()
{
Question = Confirm ("Do you really want to go into it?")
if (question! = "0")
{
window.open ("", "Test Announcement window", "width=340,height=163,toolbar=0,status=0,menubar=0,resize=0");
}
}
</script>
The following are placed in <body></body>
<a href= "" onclick= "rusure (); return false;" > To click on Me </a>
Confirm submit action with confirm, submit confirmation prompt
For example, when the guestbook click Rewrite, sometimes we want to have a hint, so as not to error operation. The code is as follows: Method one
<input name= "Submit" type= "Submit" onclick= "if" Confirm (' Do you want to open the Web page? ') location= ' http://www.05376.com ' "value=" open >
Method Two
<input name= "reset" type= "reset" onclick= "return Clearbutton ()" value= "rewrite" > <script type= "Text/javascript" > Function Clearbutton () {if (!confirm ("OK to override? ")) return false;} </script>

Two kinds:
The code is as follows:
<script language= "JavaScript" > Function delete_confirm (e) {if (Event.srcElement.outerText = = "Delete") { Event.returnvalue = Confirm ("Delete is not recoverable, are you sure you want to delete it?") "); } } Document.onclick = delete_confirm; </script> <a href= "delete.aspx" onclick= "delete_confirm" > Delete </a>
Three kinds:
The code is as follows:
if (window.confirm (' Are you sure you want to cancel the transaction? ') {//alert ("OK"); return true;} else{//alert ("Cancel"); return false;}
Four kinds:
The code is as follows:
<script language= "JavaScript" > Function delete_confirm () <!--call Method--{Event.returnvalue = confirm (" Delete is not recoverable, are you sure you want to delete it? "); } </script>
A simpler way that I used to do it myself, more simply:
The code is as follows:
<form name= "Form1" method= "Post" action= "xxx.htm" onsubmit= "Javascript:return window.confirm (' Confirm commit? ') ' >
