JavaScript - Help Needed - New To Javascript!!!
I'm working very hard to create a dynamic web-site for use in the education sector using server-side php/MySQL and client-side HTML with javascript.
I have a logon page (index.php) which looks to see if the cookie 'mylogon' is set with the value 'Again'. This cookie is set when the PHP element on the server detects an invalid username/password combination. If so I have a javascript function (see below) call from the HTML <body onload="check_invalid_user()"> I know that the function Get_Cookie is working ok and that the javascript variable 'again' has the value 'Again' in it and has a length of 5. The alert function is not executed though. function check_invalid_user() { again = Get_Cookie('mylogon'); // document.write(again); // document.write(again.length); If (again == 'Again') { alert("User-id and/or password incorrect -- Please re-enter"); } } ============= Any help would be appreciated Many thanks in advance. (Yeah you guessed it I'm new and raw to this stuff. Similar TutorialsPretty pretty please help me with this I am running out of time and pulling my hair out with this whole thing. Thanks a million in advance!

I have taken out the credit, as I have changed it a bit, but will reinstate it later on. All I really need to know is how to define it in the XHTML maybe. Can anyone help? How to create a popup blocker with javascript? I am looking for solution to open Enquiry form [Ex: send-query.php] through javascript linking. How can I do that? And how to display a popup blocker message like in the attached file? This is the url of my pop up image: http://www.rhapsody.com/thompson-squ...mpson-square-2 [When you click on play button then if you have popup blocker enabled you will get popup blocker message from the site] Hi, At www.happydaysremovals.com.estimatenew.html. Users fill in a form which has items of furniture, so they enter a number next to each item of furniture. The HTML uses text fields. When the form is submitted, the form is submitted to a php script that emails the results to myself. I am trying to also have a javascript function which runs before the php script runs. This javascript works out the cubic footage of all the items. If a user put "3" in the sofa text field, and I have defined that a sofa is 45 cubic feet, then the javascript will multiply 3 * 45. It will do a similar thing for all items of furniture, then add them all up to give a total cubic feet. I want that total field to then sent as a variable to the php script, along with all the other variables. My code so far (which doesnt work) Code: <script language="JavaScript">
function calculate()
{
var sofa_3_seater = document.getElementById('sofa_3_seater').value*45;
var sofa_2_seater = document.getElementByID('sofa_2_seater').value*30;
var armchair_large = document.getElementByID('armchair_large').value*15;
var total=sofa_3_seater+sofa_2_seater+armchair_large;
document.getElementByID('total').value = total;
}
</script>
I have used a hidden field for the total value: Code: <input type="hidden" name="total" value=""> I want the javascript result to change the value of the hidden field that is called total. THen I want it all to be posted to the PHP script and email everything to me, including this newly calculated total field! THanks I will be completely up front about this, its school work. At the end of a basic html class I missed several classes for family reasons and missed just about everything on Javascript. The book we used basically didnt cover anything over it, was all in class learning I missed. Anyone who could help would be so helpful. One function is partial, one is blank, thats what is supposed to be added/corrected to the following code Code: <html>
<head>
<script language="javascript" type="text/javascript">
function processScore()
{
var score = 0;
if ( ...checked)
{score = score + 1;}
if (...checked)
{score = score + 1;}
document.answerForm.score.value = score;
// Display the correct answers
document.answerForm.answer1.value = " "; // put the correct value here
document.answerForm.answer2.value = " "; // put the correct value here
} //End of function processScore
function clearForm()
{
// using the a javascript method clear all forms
}
</script>

thnx in advance to anyone who can help I have a vendor delivered java script code that I am currently customizing. The original code involves a user when selects a "check box" option value , a small function is called titled "VerifyAcctType". Currently when a user selects the check box some values are defaulted into the form. Now to this function code below i have to add logic when user selects the same check box option FIRST a small pop up window should appear which lists two radio buttons"I Agree to terms" and "I do not agree to terms" options , user need to select one of the options in the pop up to proceed. If the user agrees to terms then the control should go back to the "VerifyAcctType" function and proceed with remaining steps like before else if the user selects "I do not agree" the logic should not proceed further in "VerifyAcctType" function. Here is the current code tied to VerifyAcctType function ============================================== function VerifyAcctType(win,type) { var AcctType var ThisWindow var ThisForm if (win == "ADD") { ThisWindow = AddAccountWind ThisForm = AddAccountWind.document.addform } else if (win == "CHG") { ThisWindow = ChangeAccountWind ThisForm = ChangeAccountWind.document.chgform } if (type == "P") { <<I NEED NEW CODE HERE FOR THE POPUP>> Maccttype = type ThisForm.description.value = "My Company" ThisForm.comp_id.value = "1234567" ThisForm.comp_id.disabled = true } else { Maccttype = type ThisForm.description.value = "" ThisForm.comp_id.value = "" ThisForm.comp_id.disabled = false } } I am a java script beginner , any help is appreciated. Hi, I'm trying to get my head around JS, but not too successfully yet. My objective is probably simple (but not to me ): to have a form where visitors enter 12 separate digits (ideally in minutes & hours, but am happy to use decimals), and the average of these (to two decimal points) is returned as document.write is it? - along with other text, to make a complete & coherent sentence, including the average of the 12 numbers. Does anyone have any code convenient that could do this? Thanks, LJ I'm not a coder myself but I could use some help and am willing to pay if it's within reason. It's for a site I'm putting together for a hobby of mine. Here's a description of what I need done: http://masterengraver.com/ambigrams/test.html Please drop me an email with price for your time if you can do this. Thanks! / ~Sam Please see the below code. Is it possible for me to type in an order date in the browser & in the due date field, have it automatically populate a date 7 days greater than the date typed in the order date field? If so how? I have read I will probably need javascript to do this but have no clue where to start. Thanks for any help provided! <html> <head> <title> Update Database </title> </head> <body> <form method="post" action="add.php"> <b>First Name:</b> <br /> <input type="text" name="customer_fname" size="35" /><br /> <b>Last Name:</b> <br /> <input type="text" name="customer_lname" size="35" /><br /> <b>Location:</b> <br /> <input type="text" name="location" size="35" /><br /> <b>Order Date:</b> <br /> <input type="text" name="order_date" size="35" /><br /> <b>Due Date:</b> <br /> <input type="text" name="due_date" size="35" /><br /> <input type="submit" value="Submit" /> </form> </body> </html> Hello everyone, i desperatly need a script for my website but am totally stuck, I hope someone can help On my website i want a search box. I want it so that if a use types in one of my predetermined search terms then they would be sent to a predeterimed page in my own website. For example: I have a group of 5 keywords - nokia, mobile, vodafone, cellphone, iphone. If a user types any of those keywords into my search box then xxxxx.com/mobilephones.htm will be loaded up I have another set of 5 keywords - cat, dog, rabbit, mouse, snake. If a user types any of those into the search box then they are directed to xxxxx.com/animals.htm and so on ... So as you can see, its not a 'normal' search engine I will be creating new pages and will need to add the chosen keywords for it as time goes on etc Nearly everywhere i look for something to help me all I can find are standard search engine scripts which are no good as they display search results instead of directing to specific urls depending on the keywords entered I would also need to 'capture' what search terms are being entered so that I can build some user statistics I understand html and javacript to an intermediate level Can anyone help / provide a script that I could use? Although Im a student Im willing to pay some funds to anyone that can do this for me Many thanks Terry I tried to write the variable my_var into a text file but it only shows null after executing the code. Can anybody help pls?? Below is my code <html> <head> <script language="javascript"> var my_var function WriteToFile() { my_var = 123; document.write(<?php $file="file.txt"; $fh = fopen($file, 'w') or die("can't open file"); ?>; document.write(<?php $stringData = my_var ?>; document.write(<?php fwrite($fh, $stringData); ?>; document.write(<?php fclose($fh); ?>; } </script> </head> <body onLoad="WriteToFile();"> <p>Hello World</p> </body> </html> I am still learning javascript so forgive me if this question is a bad one, I am making scripts for Greasemonkey for a website I am a part of. One of the developers recently commented out (in the source code) a feature that was available before. It is a Football MMORPG game and it used to show college players 40 times but over the past month he commented out the tag that held the script function. I want to know if i can either A) write a js code that can remove the comment tag in the source code or B) write a code that will just add another tag under that and have that js function that was commented out valid. I tried something but ended up just having that function pasted onto the page instead of having it put into the source to have it read by the rest of the data.. here is what im talking about <TABLE width=800 cellspacing=0> <tr> <td colspan=3 style="FONT-SIZE: 11pt"> <b>Hometown:</b>Fort Hunt, VA<br> <b>Height:</b>6-0<br> <b>Weight:</b>206<br> <!--b>40 Time:</b><if rs("team_id")>0 or bRated then><=formatnumber(rs("forty"),2)><br><end if --> i just want to see if there was any way to just delete the comment out of it so i can get this feature again is all. Any help would be awesome... and sorry for the long post i have this line of code: Code: <a href="#" id="profilelink" name="link2" onClick="viewornot(<?php echo $freechat_id ?>)"><?php echo $freechat_list; ?></a>
//call the JS onclick and if OK was click do the message box and send button here
then i have my JS: Code: function viewornot(id)
{
var e = confirm('Do you want to view this profile?');
if (e == true)
{
window.location.href = "http://www-rainbowcode-net/apps_dev.php/profiles/showprofilepersonal?id="+id;
window.location('http://www-rainbowcode-net/apps_dev.php/profiles/showprofilepersonal?id='+id);
return true;
}
else
{
var e2 = confirm('Do you want to send a message?');
if (e2 == true)
{
//if ok was clicked send value back??
return e2;
}
}
}
on the e2 confirm: if i clicked OK how can i send a value back(so that i know OK was clicked) so that i can then produce the message box and send button and do the rest of the code to send a message??? thank you I have a page with options, and I need to hide options unless a certain choice is selected. So say you have a select box for male and female, if they select male, I need it to show male options, and if they select female, it shows female options. How can I hide things until selected and then show the textboxes and stuff? Thank you!

Hi Coders... I'm building a 'really simple' JavaScript program to help editors write SEO-friendly META titles and META descriptions. The idea is you have 3 text boxes, each on a separate line: BOX 1 - META TITLE [ i.e. "Cool website page" ] BOX 2 - FILE NAME [ i.e. "This is a really cool web page about cool stuff"] BOX 3 - META DESCRIPTION [ i.e. "cool-web-page" ] As the editor types in the boxes, a serp listing is displayed as it would appear on Google (and ideally how it would appear on Bing and Yahoo): Cool website page www.coolwebsite.com/cool-web-page This is a really cool web page about cool stuff Kudos to any one who could point a JavaScript newbie in the right direction can anybody help with these programs, the javascript must be a simple as possible 5 Functions A year six class require a basic calculator for maths class.
