Javascript : Confirm Delete

Hi I really really really need your help since I have no idea about this.

How can I insert the Javascript Confirmation Alert into the del.php file?

I have this del.php file

PHP Code:
<?php
require ("include/config.php");
$id=$_REQUEST['id'];

$strSQL = "DELETE FROM change WHERE id = '".$id."' ";
$objQuery = odbc_exec($conn,$strSQL);
if($objQuery)
{

echo "<script language='Javascript'>alert('Deleted.');
     window.location=\""."index.php?action=syif\"</script>";

}
else
{
echo "Error Delete [".$strSQL."]";
}
odbc_close($conn);

?>

This is the confirmation javascript

Code:

<html>
<head>
<script type="text/javascript">
function show_confirm()
{
var r=confirm("Delete?");
if (r==true)
  {
  alert("Deleted!");
  }
else
  {
  alert("Cancelled!");
  }
}
</script>
</head>
<body>
 
<input type="button" onclick="show_confirm()" value="Show confirm box" />

Delete Cookies With Javascript

Hi

I am working on a .net basket where I save the info for the products in the basket etc in a cookie.

Now I have an html button on the basket page where I want to be able to delete the product (Cookie).

I am using

Code:
<script type="text/javascript">
function delete_cookie ( cookie_name )
{
expires = Now();
document.cookie = cookie_Name+"= ;expires="+expires.toGMTString();
}

</script>But I get an error that says the cookie is not delcared? But it does exist because I retrive the name of the cookie when looping through the cookie list.

What am I doing wrong here?

Javascript Help Needed For Category Image Display And Delete Dynamically

Similar Tutorials

I have search for about a week and still no luck.
I need to dynamically display mutliple images using javascript, no hardcoding. The images have different categories. For ex. bellTower01.jpg, bellTower02.jpg...and fountain01.jpg, fountain02.jpg....

-Use JavaScript to display several images and scroll through them
To display multiple thumbnails, arrange them into a small quantity (no more than 8 per page)
Provide pagination

I really really really need help. I have never done javascript before, so I'm still learning. I seriously checked out many threads and links but nothing works or is what I want. I hope someone can help me out and hopefully also allow me to become better at coding this kind of stuff.

I am not allowed to code in php for this project. I can only use javascript to display the images. Also, I don't really need anything fancy, like slideshows or rotations, I just the image to appear when I select that specific category. I want to get the images from my folder/directory.

Right now, I have it working as it just being hardcoded.
Below is my code for my galleries page:

How Do I Create A Table With Number Of Rows Dependent On User Inputs? (javascript)

Similar Tutorials

Here's part of the code, problem I have is I have it set up for 5 rows, I need it to be able to make more than this, but not sure how many more, this is dependent on user input, how should I go about this? Also how would I go about making the users orders correspond with the right item number? I'd need to sort the array somehow?

document.write('<table border="1">');
document.write("<tr>");
document.write('<th colspan="5">ORDER</th>')
document.write("</tr>");
document.write("<tr>");
document.write('<th align="left">Item #</th>');
document.write('<th align="center">Name</th>');
document.write('<th align="center">Price</th>');

document.write('<th align="center">Total</th>');
document.write("</tr>");
document.write('<td align="center">0</td>');
document.write('<td>' + productName[0] + '</td>');

document.write('<td> ' + orderItemQty[0] + '</td>');

Delete 'new Obj()' Crashes Ie

Similar Tutorials

The js line...
delete new Obj();
brings my script to a halt in IE7. the error in the MS-VWD debugger is...
"Cannot delete 'new rect()".

The same line seems to work fine in FF. If I change the code to...
var o = new Obj();
delete o;
- all works fine in IE. Can someone explain why this occurs?

btw... the actual code is something like...
delete new rect().getElem(elem).hcenterInRect(parRect).setElem(elem);
so there's a bunch of processing between the new and deleting of the object ("rect").

this is obviously not a big problem but i was just curious as to how IE was interpretting this line.

thanks to any of you javascript wizards that may have a clue.

Delete Item Function

Similar Tutorials

This function is part of a page that will delete a product that a customer has selected.

The question I have is what is the line line that actually removes the item from the list of products chosen?

From my understanding, in order to establish an array, new array = elements[i] has to be added but Im thinking that elements[i] is the array that holds the product.

Does the "0" in this line actually delete the item?
document.template.elements[i].value = 0 ;

Code:

function del_item(X,msg) { 
  // var msg = "Are you sure you want to delete this line item?"
   resp = confirm("Are you sure you want to " + msg + "?") ;
   if (resp) {
      var len = document.template.elements.length
//loop to put into arrays
      for (var i = 0; i < len; i++) {
          var lname = document.template.elements[i].name ;
          if(lname == X) { 
            document.template.elements[i].value = 0 ;
            process_order(0) ; 
            document.template.loginpath.value = "CO" ; 
            document.template.submit() ; 
          } 
      } 
   } else {

How Do I Delete The Slide-effect?

I found a very intressting JS function at this webpage:
http://www.dynamicdrive.com/dynamici...edcollapse.htm

I wonder if someone knows wihich part from the JS-file i should change/delete so i only get the fade at exempel 1 and not the slide/rolling effect. I only want the fade.

The JS is:
Code:

//** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
			//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
			//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly

//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
			//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
			//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state

Image Upload With Preview And Delete

Similar Tutorials

Have the followig questions and need answers regarding the following script that will Preview a Photo before upload. The script is from http://jsbin.com/uboqu3/edit#javascript,html

1) The script works for Firefox, no good for IE. How to make it works for IE?

2) It does not have a method to delete the photo. Needs something like a small image "X" installed on the Preview Photo, clicking this "X" will delete the photo. Can anyone supply this solution?

Code:

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
function readURL(input) {
	if (input.files && input.files[0]) {
		var reader = new FileReader();

		reader.onload = function (e) {
			$('#img_prev')
			.attr('src', e.target.result)
			.height(200);
		};

		reader.readAsDataURL(input.files[0]);
	}
}
