Similar TutorialsI'm having a total brain fart as to why this is happening. I just transferred my company's website from aplus.net servers to a linux based server on GoDaddy. My company's "shop" page has a drop down menu which should automatically re-direct you to a different page (on a different website where our shopping cart is hosted) when the option is selected. For some reason, after the switch to a different host, the option tags are no longer re-directing to the proper pages. Instead, they just tack on the value URL onto the existing URL and i just go in circles. javascript: <script language="JavaScript" type="/text/javascript"> function nav() { var w = document.myform.mylist.selectedindex.html; var url_add = document.myform.mylist.options[w].value; window.location.href = url_add; } </script> HTML for options form: <FORM NAME="myform"> <SELECT NAME="mylist" onChange="nav()"> <OPTION VALUE="http://bedvoyage.com/shop">Select Your Product <OPTION VALUE="http://bedvoyage.myshopify.com/products/twin-sheet-set">Sheet Set - Twin - $139.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/double-sheet-set">Sheet Set - Double - $159.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/queen-sheet-set">Sheet Set - Queen - $179.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/king-sheet-set">Sheet Set - King - $199.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/twin-pillow-case">Pillow Case - Twin - $20.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/double-pillow-case">Pillow Case Set - Double - $40.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/queen-pillow-case">Pillow Case Set - Queen - $42.00 <OPTION VALUE="http://bedvoyage.myshopify.com/products/king-pillow-case">Pillow Case Set - King - $45.00 <option value="http://bedvoyage.myshopify.com/products/zippered-travel-pillow-case">Zippered Travel Pillow Case - $19.00 <!-- <OPTION VALUE="http://bedvoyage.myshopify.com/produ...uot;>Travel Blanket - $39.00 --> </SELECT> </FORM> Is there an option on godaddy that i'm just missing out on that i'm too ignorant to notice?

Hi, I am very new to Javascript and am having some difficulties with implementing two forms on the same page. The page in question is http://www.devoteddomains.com/contac...ed-domains.asp. The form at the top appears on every page and works on all of the other pages except this one. When you try to complete the form it validates the second form on the page. The code for the top form can be found he http://www.devoteddomains.com/web-de...vices-cta.html (it is an include file). The two scripts that I am using are as follows: Top Form: http://www.devoteddomains.com/scripts/scripts.js Contact Page Form: http://www.devoteddomains.com/scripts2/scripts.js Can someone please help! Cheers, Peter Hi, I am trying to produce a form which customers fill in to acquire a car park permit for my car park. In the form, I take details of reg plate, make and model, colour etc, and also take the period of time they are paying for (1-6 months) and the date in which they want their permit to start (either immediately or they select the date from the calendar). I was trying to implement a script that I found online into my form so that it will show them on the form when the expiry date of their new permit will be. However, when I try to use the script, and click on the button that I produced to work out the expiry date, it submits the form and takes them to checkout without filling out the expiry date. Please can someone help me?! Kind Regards, Dan. Hey guys, I use a newsletter service called Aweber to handle my blog's subscription service. What I have right now is a simple HTML form that I can have pass its variables through to a thank you page, so I can add customization there. The web form looks like this: Name: ________________ Email: ________________ Choose a free gift!: drop down list with "gift1" "gift2" or "gift3" as the choices. When a user submits the form, it will bring them to a custom thank you page, which I have made as "thank-you.php". On the "thank you" page, there is a javascript code that was given by Aweber which basically loads up all the variables... you can then CALL all of the variables in the page like this: <script type="text/javascript">formData.display("name")</script> ========================== So what's my question? I wanted there to be a display on the bottom that would allow users to download a different gift based on whether they chose gift 1, 2 or 3. I would also love to have there be an image of the ebook next to the download link depending on which book they chose. Is there a way I can pass variables through into an html <img> tag? (i.e. src="http://www.website.com/formData.display("gift").jpg" ... or something like that). Building off this, how would I generate a different download link based on the choice they made in the web form? (i.e. <a href="http://www.website.com/formData.display("gift").pdf"> or similar) Hopefully this all makes sense, let me know if you can help! i am new to JavaScript and i have an assignment to create a tour calculator here is the code and its not working please help its urgent thanks.

Is it possible to use Javascript to set the name of a tag to be the tag's id? For example, something like this: Code: <input type="text" id="textInput" name="this.id"> The example code above doesn't work. The reason I'm asking is because I have a complex form that uses Javascript to change ids a lot (the input fields are dynamically created). When I was coding the form I completely overlooked the fact I need to use the name tag to process it with PHP. (to enter it into a mysql database) It'd be a pain to have to go through all my javascript and change the name where ever I change the ids. If need be, I'll do this, but I'm just looking for an easier way.

<input type="hidden" name="prodid" value="Product1" />
<a href="javascript: AddToCart()">
<img src="/images/design/buynow.gif" />
</a>
</form>
However, it doesn't work, since i have the same value under the name of each form: "_cart". Is there any way i still can send a form regardless the name of the form? I tried to use "onclick", like this: Code: <a href="javascript: void(0);" onclick="document._cart[0].submit();return false;"> However, i still have to change the value under the _cart element from 0 to the number of my forms. I need just submit a form itself, with the same form names. For some reason i cannt use the html submit button. Everything should be done with JavaScript. I beleive this text is not hard for understanding ) Look forward to your help Guys. I cannot get the result right. I write area and phone by numbers but it still gives me error Code: function validate_text(field,alerttext) {
with(field) {
var re = /[a-zA-Z]/g;
if(re.test(field)) { return true;}else{alert(alerttext);return false;}
}
}
function validate_number(field,alerttext){
with(field) {
var re = /[0-9]/g;
if(re.test(field)) { return true;}else{alert(alerttext);return false;}
}
}
function validateForm(thisForm){
with(thisForm)
{
if(validate_number(area,"wrong area code") == false) {
area.focus();return false;
}
if(validate_number(phone,"wrong phone") == false) {
phone.focus();return false;
}
if(validate_text(name_surname,"wrong name") == false) {

I have found a code to help me learn how to add forms in javascript, but it's limited to text input forms. Code: <script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number. Code: <input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" /> This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15. Is this possible? Hello, this is my first post here, but I'm having some trouble figuring out what I messed up on my code I'm making a Javascript game of Hangman for one of my classes and I originally had the input as a text box where you physically type in the letter and if it was wrong, it would draw the next sequence of the hangman picture and place the letter in another text box as a "Used Letters," or if you're right, it would place the letter you chose in the box for the word you're guessing. However, I decided that instead of doing that, I wanted to make it more visually appealing and add buttons with the letters on them instead. As you can see in the code which is down-loadable here (the one with the _2 is the one I'm currently using, but the original is supplied as well), the buttons register for the picture changing, but do not register for the "Used Letters" field or for filling in the actual word. One of the button's values is also replaced by "undefined" after each click of another button and I'm not really sure why If anyone could take a look at my code and see if you can figure out what the deal is, that'd be awesome! Hello all! I am using 'simplecartjs' as a simple shopping cart for my website. To checkout, the user e-mails me his cart containts. I would like to have his name, email and adress with this but i'm unable to add this to my shopping form. Here is my JS: Code: me.emailCheckout = function() {
itemsString = "";
for( var current in me.items ){
var item = me.items[current];
itemsString += item.name + " " + item.quantity + " " + item.price + "\n";
}
var form = document.createElement("form");
simpleCart.empty();
form.style.display = "none";
form.method = "POST";
form.action = "sendjs.php";
form.acceptCharset = "utf-8";
form.appendChild(me.createHiddenElement("jcitems", itemsString));
form.appendChild(me.createHiddenElement("jctotal", me.total));
document.body.appendChild(form);
form.submit();
document.body.removeChild(form);
}
And here is the PHP that sends is (sendjs.php): Code: <?php
$to = 'info@kheuning.nl';
$subject = 'the subject';
$jcitems = $_POST['jcitems'];
$headers = 'From: webmaster@example.com' . "\r\n" .
'Reply-To: webmaster@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $jcitems, $headers);
Header('Location: thankyou.html');
?>
I understand how to add variables to send in my php form, but it doesn't take normale html form input's i add to the page. How can i add these to the js? Thanks in advance! Jonas I am trying to make it when a user comes to a site, if they have been there before an alert box will open saying "Welcome firstname, lastname, and email address".

Hello, I am developing a contact form and I have the form fully working but all I want is for when you fill out the contact form and submit it, a Lightbox window shows the confirmation page instead of it opening in the whole window. I have tried everything I can think of (I am a complete newbie with JS) so I am hoping one of the nice experts here could help me out. The form is located he http://tomabyte.co.uk/FORM-SPACE/ If someone could help me I would highly appreciate it. Cheers, Tom. Hello everyone at CodingForums! This is my first post on this site and I would really appreciate any help I can get, First off, all I am trying to do is have someone enter one value into a field then another value into the second field, then have javascript subtract those numbers. This is my first time trying to do something on my own without tutorial help, so I am for the most part just stumbling in the dark. here is what I have thus far: Code:

{
var difference;
difference = lastMonth - thisMonth;
form.Fdiff.value = difference;
}

I'm going off of the code found at this site "http://www.javascriptkit.com/script/cut141.shtml" for a calorie counter. the way the code is now, I get a NaN in the difference box. Again, I would appropriate ANY help and guidance you guys could provide. Thanks I currently have a page which, when the user clicks a button creates a new row displaying a form. I also have other forms on this page however so I was wondering if anyone knew how to close a form using javascript? Thanks for any help. My code to create the table row and form are below... Code: myform = document.createElement("form");
myform.method = "post";
myform.action = "editdetails.php";
myform.id = "editemail";
myform.name = "editemail";
var a=document.getElementById('editdetailstable').insertRow(2);
var b=document.getElementById('editdetailstable').insertRow(3);
var x=a.insertCell(0);
x.innerHTML="New Email: ";
x.align = "right";
var y=a.insertCell(1);
y.innerHTML="<input type='text' name='email' id='email' />";
var z=b.insertCell(0);
z.innerHTML="<input type='button' value='Change' />"
z.colSpan = "2";
z.align = "center";
I wonder if someone can help me. I've recently put together a new web form. The form is validated using JavaScript - it shows real-time error messages when forms are left blank, and also prevents the form from being submitted if any of the input data is invalid. The problem I have is that if JavaScript is disabled, the form cannot be submitted. At the moment I am submitting the form using the following button Code: <input type="button" value="Next" onclick="submitForm(this.form);" id="button" /> The 'onclick' event runs the 'submitForm' function, which runs a final validation check and submits the form if everything checks out. If there is invalid data in the table, an alert box pops up which prevents the form from submitting. Unfortunately, if JavaScript is disabled, the 'Next' button does nothing, as it is relying on JS to submit the form. I have tried using <input type="submit"> as well as <button type="submit">. Both of these allow the form to be submitted if JS is disabled. Unfortunately, when JavaScript IS enabled, the validation gets bypassed - the alert box still shows up but once you click 'OK' the form gets processed anyway. Can anyone suggest a solution? I am planning to write server-side validation in PHP as a backup but would prefer it if my JavaScript validation would work in it's entirety and the PHP simply be in place as a last line of defence for when JS is disabled. Thanks! I need to implement a function in JavaScript to calculate the total of the purchase which is equal to price of each tool * quantity ordered* sales tax=.08. I also need to use confirm() to display the total cost of the purchase so the user can see it. If my user confirms the order by clicking ok then but clicking cancel will terminate the order. <!DOCTYPE html> <html> <head> <title>Form</title> <meta charset="UTF-8" /> <body> <h1 style="text-align:center"> Hardware Store</h1> <form action="http://www.yahoo.com/formtest.php"> <p> <label> Buyer's Name: <input type="text" name="name" size="30"/> </label> <label> Street Address: <input type="text" name="street" size="30"/> </label> <label> City, State, Zip: <input type="text" name="city" Size="30"/> </label> </p> <table> <tr> <th> Tool Name </th> <th> Price </th> <th> Quantiy </th> </tr> <tr> <td> Hammer </td> <td> $12.00</td> <td> <input type= "text" name="Hammer" size="2" /> </td> </tr> <tr> <td> Shovel </td> <td> $18.00 </td> <td> <input type="text" name="Shovel" size="2" /> </td> </tr> <tr> <td> Trimmer </td> <td> $22.00 </td> <td> <input type="text" name="Trimmer" size="2" /> </td> </tr> </table> <h2> Payment Method </h2> <label> Visa <input type="radio" name="payment" id="payment_visa" value="visa" checked="checked"/> </label> <br /> <label> Mastercard <input type="radio" name="payment" id="payment_mastercard" value="mastercard"/> </label> <br /> <label> American Express <input type="radio" name="payment" id="payment_american_express" value="american express"/> </label> <br /> <input type="submit" value="Submit" /> </form> </body> </html> |
