Update Text As Numbers Are Typed Into Input Field

Jul 22, 2010

I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

Onfocus Text Disapears, On Blur Text Reappears If Nothing Is Typed In?

Jan 9, 2010

im trying to implement a login screen similar to Facebook. What i mean by this is i want the username and password fields to have text in them until the user selects the textfield. If the user does not type anything in the textfield the the onblur will automatically change it back, but if the user has typed something in then i want the text to be left alone.At the moment the onblur always changes the value of the textfield. Im not sure how to solve this.(code i am using is below)

Code:
<input name='username' type='text' size="10" value="username" onfocus="this.value=''" onblur="this.value='username'"/>

Validate Three Textboxes And It Will Validate For Numbers?

Feb 19, 2010

I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

[code]....

I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.

Text Being Typed And Then Vanishes ?

May 25, 2010

I want a script that "types" my text letter by letter and also deletes the text letter by letter. I want it to look as if someone is typing the text live, and then when the start of the text deletes (letter by letter), it would start from the beginning, erasing the letters in the same pace new letters are being "typed". So this way you would never see the whole text, but only a bit of it at a time. By the time you would get to the end of the text, the beginning wouldn't be there. And I don't want the text in a box!

Allows ONLY Decimals To Be Typed Into A Text Field

Apr 11, 2011

I have a script that allows ONLY numbers to be typed into a text field. I have tried to modify this script to allow Decimals (periods) to be typed as well, but haven't succeeded. The code in Red are the changes I added to this script, but it isn't working out.

function numbersOnly(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57) && (charCode < 110 || charCode > 110))
return false;
return true;
}

Second Problem: I need to set a Minimum number users may type in the text field. Normally this would be a simple task, but the minimum number they may type is a decimal (0.10). The default value in the field is .50. I tried replacing the .50 with .09, and I can't get the field to run the script and set its new value to .10 (<- this is the minimum). Here is the code I am working with.

Run A Function When Text Is Typed In An Input Field?

Jul 15, 2011

I want to run a function when text is typed into an input field. So every time 1 character is put in it will process a function. However I do not know how to accomplish this. I tried the onchange attributed but that seems to only work when you unselect the input field.

how this might be accomplished? I'm also comfortable with jQuery if you think that's a better option.

Feb 11, 2010

have a form with three fields for home phone, work phone & mobile phone.I've got jquery to validate that the numbers entered are the right format, i.e. using the following with custom methods for the phoneUK etc.The thing is I only need one of these numbers. I have been trying *all day* to try and get this to work but no joy. I know I need to group them somehow but can't figure it out.I want it so I get a single message if all fields are left empty and then if a field does have an entry then it's validated to ensure its a number.

Total Price To Be In DIV And Not Input Type Text

Dec 5, 2010

Firstly, I got this script which gets values and automatically calculates it and shows result.
Script:
<script type="text/javascript">
function calculate(f){
var prod=Number(f['users'].value);
var quan=Number(f['months'].value);
var tot=prod*quan;
f['total'].value=tot==0?'':tot.toFixed(2);
}
</script>
<ul><li class="bold">Users</li>
<li>
<select name="users" onchange="calculate(this.form)" id="users">
<option value='1'>1</option>
<option value='2'>2</option>
</select>
</li></ul>
<ul><li class="bold">Period</li><li>
<select name="months" onchange="calculate(this.form)" id="months">
<option value=''>Select Months</option>
<option value='1'>1 Month</option>
<option value='2'>2 Months</option>
</select></li></ul>
Total: <input type="text" name="total" readonly="readonly">

What I'm trying to make is, the total, to be in a div and not input type text
Something like <div id="total"></div>
I don't like because it shows in form, I want it directly. One more thing, is possible to make the default price 0.00 ? and when selecting automatically changes to price..

Numbers From A Text Box For Calculation

Mar 7, 2006

I have the two text boxes on a form, both of which a user enters a
number. I simple need to ADD THESE UP!

I know, its daft, but no matter what I do, it just adds them together.

Example: 1+1 is clearly 2, but it outputs 11!

An example of my code:

var loan = document.loandata.loan.value;
var other = document.loandata.other.value;

total = (loan+other);
