Javascript is readable code during parsing. Every body can turn on off
popup blocker of browser .... easy way of full risk for user of browser.

You want control GUI of browsers and popup-blockers with javascript
during parsing of webpage - all browsers in same way --> in use of
html DOM ?

I think: NOT possible.

So see http://www.w3schools.com/htmldom/dom_intro.asp

Using Javascript to list local directory contents

I am building an interface that will be run only locally on users computers using HTML (no web servers involved). What I'd like to do as part of this project is to be able to list the contents of local folders related to this project. Meaning I have a parent folder that will contain all the HTML pages as well as folders with PDF files in them. From my main page I'd like to have a link to those folders and when visited, that link would list the files in that folder. This way, when additional files are added or when files are deleted, the listing will reflect the actual folder contents. Right now this works by linking to the folders and getting the raw Directory listing but the listings are not pretty. I am looking for a more elegant way to achieve this.

Anyone know how to do this with HTML or Javascript?

Thanks,
Craig

Drag & Drop jQuery to table rows and update database?

I've spent days looking for a way to use jQuery drag & drop with table rows but have only been able to find ways to save/update the database for list items, not rows. The other issue I have is that my page only has one row and pulls from a database with a repeat region loop that creates new rows so I have no way to create id's for each new row. If anyone can help me out with a script that would update my database after a jQuery drag & drop, I'd really appreciate it. Here's an example of my code that works except for the updates:

<pre lang="PHP">

<?php require_once('Connections/dragdrop.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$maxRows_rsView = 10;
$pageNum_rsView = 0;
if (isset($_GET['pageNum_rsView'])) {
  $pageNum_rsView = $_GET['pageNum_rsView'];
}
$startRow_rsView = $pageNum_rsView * $maxRows_rsView;

mysql_select_db($database_dragdrop, $dragdrop);
$query_rsView = "SELECT * FROM records";
$query_limit_rsView = sprintf("%s LIMIT %d, %d", $query_rsView, $startRow_rsView, $maxRows_rsView);
$rsView = mysql_query($query_limit_rsView, $dragdrop) or die(mysql_error());
$row_rsView = mysql_fetch_assoc($rsView);

if (isset($_GET['totalRows_rsView'])) {
  $totalRows_rsView = $_GET['totalRows_rsView'];
} else {
  $all_rsView = mysql_query($query_rsView);
  $totalRows_rsView = mysql_num_rows($all_rsView);
}
$totalPages_rsView = ceil($totalRows_rsView/$maxRows_rsView)-1;

most of the code in your post is PHP so not sure what you are looking for help on? usually my experience has been people post questions about things they have tried and need help getting it to work.

still wanting to help and considering you are using jQuery I found the following:

http://datatables.net/forums/discussion/1077/drag-drop-rows/p1[^]

I use datatables [^] in my development and I am sure you can fashion it to what you are trying.

that or you can wait for the datagrid component that will come from the jQuery folks sometime soon. http://wiki.jqueryui.com/w/page/34246941/Grid[^]

Javascript / JQuery pop-up message question

AeonBlue30-Nov-11 4:59

AeonBlue

30-Nov-11 4:59

System:
Visual Studio 2010
.Net 4.0
JQuery 1.4.2

I will start this off with a caveat that I am by no-means a javascript guy and am pretty new to JQuery.

I'm writing a page that has a several-step process to scheduling an appointment. We are accomplishing this using a multi-view control to navigate through the several step process.

Like any good user-friendly site, I have set up a pop-up message in javascript that alerts the user if they try to navigate away from the page or refresh the page, close their browser, etc. before they finish scheduling their appointment that they will lose any unsaved data (much like the person who posted just before myself).

To get around the navigation buttons for the multiview triggering the onbeforeunload event, I use the following, triggered by the onClientClick event of the buttons:

JavaScript

<script type="text/javascript">
    LinkBit = true;

    window.onbeforeunload = function () {

        if (LinkBit) {
            return "Leaving this page will cause all unsaved data to be lost";
        }

        LinkBit = true;
    }

    function TurnOffMessage() {
        LinkBit = false;
    }
</script>

The next problem we ran into is that one of our controls within the multiview, an ASP:Calendar was triggering the onbeforeunload event, causing the popup to occur when the user was trying to select a date.

To get around this we used the following JQuery within the control with the calendar wrapped in a div tag with the ID of "calendar":

ASP.NET

<div id="calendar">
<asp:Calendar ID="CalendarforAppointments" runat="server" miscStyling/Events>
</asp:Calendar>
</div>

JavaScript

<script type="text/jscript">
             $("#calendar a").bind('click', function () {
                 TurnOffMessage(); 
                 return true;
             });
</script>

This solution is dangerously close to solving my problem. My issue that I'm coming to you all for help is that the above JQuery does not affect the month navigation on the calendar control so the popup still pops-up when the user tries to change which month they're viewing.

If I use the above on the main page and wrap the control in the same div it ends up killing all pop-up functionality.

I appreciate any help you all can provide.

The first question would be is $("#calendar a") finding the elements and applying the click event?

I am guessing that the above code is located in the head of your html document. The bind won't work because the document (html) has not been loaded yet.

Simple solution - move your javascript code down towards the end of the file. In general I place jQuery script right before the closing of the body tag.

while it is permitted to put javascript in the head of your document best practices generally dictate that you place code for working with the document at the end prior to closing the body.

this will assure that "most" everything is currently in the document. the exception being any html generated code from jQuery (plugins, etc.).

Thanks, that was indeed a very good guess. I did, however, notice my error shortly after posting this and moved it to the bottom of the main page and achieved the same results as I had before: Clicking the days doesn't affect the pop-up but clicking the months does.

the reason being is because the asp:Calendar is a server rendered control.

so changing the month causes the need for the control to be re-rendered. personally I have never been a big fan for many of the asp controls. since you are using jQuery might I recommend you use a jQuery plugin and just eliminate the need for a server rendered control??

Confirm dialog with OK ,CANCEL buttons on window close

24-Nov-11 20:20

Hi,
i have an popup which is an aspx page and when i click on browser close button..., the system should check if there is any unsaved data in the form or not. If there is any unsaved data then the message should be displayed (Do you want to leave..?) with OK and Cancel button...
On click of the OK button, the data should not be saved and the user should be returned parent form ie popup should be closed and return to the parent form.On click of the cancel button, the control should return to the Pop.

I had tried the below code...

window.onbeforeunload = close;
function close() {
var result=confirm("Do you really want to close this window");
if (result) {
return true;
}
else {
location.href = document.URL;

}
}
The above code is not working ie the popup is getting closed even on click of closse button....
and when clicked on OK it is dispalying another msgbox with leave this page and Stay on this page buttons...

Please help me regarding the same...

I wish the following may solve u issue.

<script language="javascript">
function close() {
	
	var flgDataUnsaved = false;
	// do your unsave data check here
	
	
	// if there are unsaved data set flgDataUnsaved = true;
	if ( flgDataUnsaved ){
		event.returnValue = "Do you really want to close this window";
	}else{
		event.returnValue = true;
	}
}
window.onbeforeunload = close;
</script>

and u can put a "save" button on your popup page. The user can save the data themselves.

Good day,Good job,Good life

I believe this line

should be

JavaScript

event.returnValue = confirm("Do you really want to close this window");
