client side ?

[Guest]

hey all,

i have a html image with style.visibility:hidden.
i have a button running client-side script to make the image
style.visibility:visible

however, when i click the button it displays the image real fast and then
disappears again. can someone please explain this to me?

thanks,
rodchar

Rodchar,

Can you post some code?

Cheers

your button is probably posting back, causing the page to re-render.

The button is posting back and causing the page to get re-requested.
Client-side set attributes aren't preserved during postback.

If you want the postback to happen, you'll need to detect the postback and
set the image style before render.

If you don't want the postback, perhaps use an HtmlInputButton instead of a
WebControls.Button or something...

If you use a server-side <asp:button> rather than a client-side, HTML <input
type="button"> then clicking the button makes a round trip to the server and
reloads your page, thus resetting the defaults.

Use an HTML button.

<script language="javascript">
function fillin()
{
document.getElementById("Image1").style.visibility="visible"
}
</script>

<TD><IMG id="Image1" alt="" src="loading.gif" style="VISIBILITY: hidden"></TD>

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Me.Button1.Attributes.Add("onClick", "fillin();")
End Sub

Rodchar,

if you click the button your js fires and makes the image visible but the a
postback appears which will result in the image beeing hidden again.

Does this make sense?
