I have a request from a client to have four text fields added together as soon as they input the number.
They want the numbers to add together with out having to hit a submit button or have the page change. I have seen and been able to get two out of the four to add together but i can't get the rest. this is the code i have been trying to work with:
[CODE]
function calc(A,B,SUM) {
var one = Number(A);

View 5 Replies View RelatedI've been following this tutorial (and it works great)URL...Just cannot figure out how to make one of the Text Fields a Text Area with cols="45" rows="5".Every combination I've tried turns off the validation. I've already added completely different text fields from what are shown in the tutorial so I know how to change up the javascript I just can't get the Text Area right.

View 7 Replies View RelatedI have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
<table>
<tr>
<td>
<input type="hidden" name="on1" value="Size" maxlength="200">Size</td>
[code].....
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.
how do i display pre-set values in text fields such that as soon as the text field becomes active, the values vanishes
View 4 Replies View RelatedHere is my code:
if(document.myForm.minbid.value > parseInt(document.myForm.bid.value)) {
alert('Your bid amount MUST be higher than the starting bid price');
myForm.bid.focus()
return false;}
This is the section I am working with. Now this checks a form field called minbid against a form field called bid. These are both text fields. This works great using this example:
minbid = 20.00
bid = 1.54
In that case the alert will popup because bid is less than minbid, however in this case:
minbid = 20.00
bid = .54
It does NOT show the alert and allows the form to submit. Any ideas here?
When the user clicks a certain radio button, I want three text fields to become disabled.
HTML Code:
<label><input name="s_type" type="radio" value="ftp" />FTP</label>
<label><input name="s_type" type="radio" value="http" />HTTP</label><br><br>
Server:
<input name="ftp_server" type="text" id="ftp_server" size="35" /><br>
Username:
<input name="ftp_username" type="text" id="ftp_username" size="35" /><br>
Password:
<input name="ftp_password" type="password" id="ftp_password" size="35" />
Could anyone show me how to disable all the text fields above when the user clicks the "http" radio button?

function updatesum() {
document.form1.totalfat.value = (document.form1.satfat.value -0) + (document.form1.monofat.value -0) + (document.form1.polyfat.value -0);
}[code]
[icode]
<body onload="updatesum()">
<form name="form1" method="post" action="./submitFood">
<table width="520" border="0"> .....
I like to sum the values from the "satfat", "monofat" and "polyfat" text field into "totalfat" textfield. The values in those 3 text field is retrieve from database. However, when it add up the 3 values, it will not be in decimal place instead it will be in 30.10000000000000000000000002. How do I solve it and how to go about editing the code.
I've tried to do it using the funciton below, it cycles through allright, but only highlights each field whilst it is in focus, then loses it when it moves to the next field. The result is that only the last text/textarea within the form is highlighted. My aim is to highlight all fields for subsequent spell checking.

I've created two form fields (username, password).When a user comes to the page, the word "Username" is shown in the first form field. The word "Password" is shown in the second field. When a user clicks inside the field, the word inside the field erases automatically, allowing them to type in their username. Everything above is working, except I'm running into some problems.
1st: I need to figure out a way to include an if statement, that displays "Username" once again, if they did not type anything in the username field, and they clicked outside of the field. This will be the case for the Password field as well.
2nd: If a user types in their username in the username field, then types in their password, but clicks on the Username field once again to fix a typo, it completely erases their username from the field, making them have to type it all again.

I have seen many character counter scripts (with feedback), to count the characters of a text box. However, I am trying to accomplish the same thing however need to make sure the combined value of two text boxes don't exceed a limit. Ie... there is a visual countdown of number of characters remaining (val) of the two text boxes combined, and an error pops up if it is exceeded.
View 1 Replies View RelatedI have a small shopping card which has text fields named
quantity_4, quantity_10... (quantity_{orderid_here})
Customer can update quantity fields and then update form by clicking on update button. But then I wanna read all quantity fields, but there are more fields than only quantity.
So it should be something like this I think
for (i=0;i<this.form.items.count-1;i++){
myfield=this.form.items(i)
if insrt(myfield.name with "quantity_")
check every char at myfield.value
}

I have a client who wants to automatically send coupons that are selected by the customer on this page. Now, this will be handled by a mailing list software but it was suggested by the support team that the input fields (labeled coupon#_#) could be populated by using Javascript. There are 3 coupons and here's how have them structured:
Code:
<div class="coupon1">
<hr />
<img src="images/logo-wow.png" width="188" height="81" />
<address>

I have 2 input fields.
Input 1: Website URL
Input 2: Website Directory
Firstly I would like the "http://" to automatically appear in input one and two and it can't be edited or removed. Then whatever is typed in input one, I would like it to automatically copy into input 2, and the user can't delete whats in input 2 without going through input 1. Then lastly the user can add data into input 2, without input 1 changing.
Here is an example:
Red = Can't be deleted Green = Can be changed Blue = additional text to input 2
Input 1: http://www.yourwebsite.com/
Input 2: http://www.yourwebsite.com/extra/directory
How to do this?
They are not very expert in javascript. I created a script that needs to calculate the sum of text fields. My function is limited to 5 elements, you can simplify and make it work for n elements.
PHP Code:
<script>
function somma() {
var a=eval(document.getElementById("primo").value);
var b=eval(document.getElementById("secondo0").value);
var somma0=(a) - ((a) * (b)) / 100;
var somma0=Math.round(somma0 * 100) / 100;
document.getElementById("somma0").value=somma0;
var b1=eval(document.getElementById("secondo1").value);
var somma1=(a) - ((a) * (b1)) / 100;
var somma1=Math.round(somma1 * 100) / 100;
document.getElementById("somma1").value=somma1;
var b2=eval(document.getElementById("secondo2").value);
var somma2=(a) - ((a) * (b2)) / 100;
var somma2=Math.round(somma2 * 100) / 100;
document.getElementById("somma2").value=somma2;
var b3=eval(document.getElementById("secondo3").value);
var somma3=(a) - ((a) * (b3)) / 100;
var somma3=Math.round(somma3 * 100) / 100;
document.getElementById("somma3").value=somma3;
var b4=eval(document.getElementById("secondo4").value);
var somma4=(a) - ((a) * (b4)) / 100;
var somma4=Math.round(somma4 * 100) / 100;
document.getElementById("somma4").value=somma4;
}
</script>
<input type="text" id="primo" onKeyUp="somma()" /><br /><br />
<?php for($i=0;$i<=4;$i++) { ?>
<input type="text" id="secondo<?php echo $i; ?>" name="secondo" onKeyUp="somma()" value="6" />
<input type="text" id="somma<?php echo $i; ?>" /><br />

Why doesn't this work? :-

I want to disable three textareas when one checkbox is ticked. how would i go about doing this?
My code:
I am having a dickens of a time figuring out how to add an event handler that clears my text fields when the clear button is clicked. This is the code that I've done but to no avail.
var $ = function (id) {

var calculate_click = function () {
var investment = parseFloat( $("investment").value );
var annualRate = parseFloat( $("rate").value );
var years = parseInt( $("years").value );
$("futureValue").value = "";
if (isNaN(investment) || investment <= 0) {
alert("Investment must be a valid number\nand greater than zero.");
} else if(isNaN(annualRate) || annualRate > 20) {
alert("Annual rate must be a valid number\nand less than or equal to 20.");
} else if(isNaN(years) || years > 50) {
alert("Years must be a valid number\nand less than or equal to 50.");
} else {
var monthlyRate = annualRate / 12 / 100;
var months = years * 12;
var futureValue = 0;
for ( i = 1; i <= months; i++ ) {
futureValue = ( futureValue + investment ) *
(1 + monthlyRate);
}
$("futureValue").value = futureValue.toFixed(2);
}}
var clear_click = function () {
var investment = parseFloat();
var annualRate = parseFloat();
var years = parseInt();

window.onload = function () {

If I run a separate function that just sets all form field values to zero (including the first line of this function). The summing works!!! Why won't it work the way I wrote it??? It won't work if I set the default value for the sum field to zero, either...
