How do I make one of those hyperlinks where when you click it, it will display a popup asking "are you sure?"
<INPUT TYPE="Button" NAME="confirm" VALUE="???" onClick="message()">
I already have a message() function working. I just need to know what the input type for a hyperlink would be.
<a href="http://somewhere_else" onclick="return confirm()">
When the user clicks the link, the
confirm function will be called. If the confirm function returns
false, the link traversal is cancelled, if true is returned, the link is traversed.
<a href="http://something.com" onclick="return confirmAction()">try to click, I dare you</a>
with the function
var confirmed = confirm("Are you sure? This will remove this entry forever.");
(you can also return the confirm right away, I separated it for the sake of readability)
Tested in FF, Chrome and IE
As Nahom said, except I would put the
message routine must not only ask the question, but also use the answer: if positive, it must call submit() on the form to post the form. You can pass
this in the call to ease the fetching of the form.
Personally, I would go for a button (input tag as you show) instead of a simple link to do the process: it would use a more familiar paradigm for the users.
[EDIT] Since I prefer to verify answers I give, I wrote a simple test:
var answer = confirm("Are you sure you want to do this?");
<form action="Tests/Test.html" method="GET" name="subscriberAddForm">
<input type="hidden" name="locationId" value="2721"/>
<input type="text" name="text" value="3.1415926535897732384"/>
<input type="button" name="Confirm" value="Submit this form" onclick="AskAndSubmit(this)"/>
Yes, the submit just reload the page here... Tested only in FF3.
[EDIT] Followed suggestion in the comments... :-)
<a href="#" onclick="message(); return false;">???</a>
This answer would be OK only when the click need NOT navigate the user to another page.
