Page Fully Loaded

[remerge]

Not quite a Lasso question.
I have a very long entry form with a couple of edit buttons on it.
If one of the edit buttons is clicked before the page is fully loaded
information on the fields below the edit button are not entered.
Is there a way to make the edit buttons active only when the page is
fully loaded?

Thanks

Charles Gorenstein

You can use JavaScript to accomplish this.  Set a variable at the top of the page to false.  Set the variable to true at the bottom of the page.  In the middle, you need an onclick handler on your submit buttons that checks the variable value (if the onclick returns false then the mouse click is ignored).  The buttons should be disabled until the page has finished loading.

<script language="JavaScript">var doneLoading = false</script>

<form response="[response_filepath]" method="post">
        <input type="submit" name="submit" value="submit" onclick="return doneLoading" />
</form>

<script language="JavaScript">var doneLoading = true</script>

Hope this helps,

I can think of two methods: have the buttons disabled until a  
Javascript activated onLoad enables them, or test for the presence of  
the last form parameter on the page and if it's not present return a  
status code of 204. I personally like the latter since it's server  
based instead of client based, but both could be used together if you  
like.

On the response page use code like:

     If: !(((Client_PostParams) -> (Find: 'lastelementname')) -> Size);
         $__http_header__ = 'HTTP/1.0 204 No Content\r\n';
         $__http_header__ += 'Server: Lasso/7.0\r\n';
         $__http_header__ += 'MIME-Version: 1.0\r\n';
         $__http_header__ += 'Content-type: text/html; charset=UTF-8\r
\n';
         $__http_header__ += '\r\n';
         $__html_reply__ = '';
         Abort;
     /If;

Thanks Fletcher and Douglas.

I opted for the javascript solution since we are on an intranet.

Kind regards,
Charles Gorenstein
