  • jQuery - Form input return confirm to delete

    - by bruno
    hello guys. I struggled a lot before posting here :) now, I want to replace my default javascript confirmation for deleting a file. I saw a lot of examples here, but no example with form input. Now I have his form: <form action="delete.php" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="<{$lang_del_pic}>" onclick="javascript: return confirm('<{$lang_confirm_del}>');" /> </form> Now, I did everything, I have this div: <div id="dialog-confirm" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p> </div> this javascript: <script type="text/javascript"> $(document).ready(function() { $("#dialog").dialog({ autoOpen: false, modal: true }); }); $(".confirmLink").click(function(e) { e.preventDefault(); var targetUrl = $(this).attr("href"); $("#dialog").dialog({ buttons : { "Confirm" : function() { window.location.href = targetUrl; }, "Cancel" : function() { $(this).dialog("close"); } } }); $("#dialog").dialog("open"); }); </script> and this new form: <form name="dialog-confirm" id="dialog-confirm" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="" id="opener" /> </form> On press, I call successfuly the jQuery modal diolog, and everything works, but somehow, when I press 'delete all' the script tells me - "the script is called without the necessary parameters" Now I guess I am failig to send the pic ID to be deleted with the jQuery, .. but do not know how to fix it. Any ideas ?
