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.

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'"/>

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.
I have a form with two text input boxes. I want to limit the text typed into the boxes as follows:
1. Either box can have the number 2 typed in, but the other box must remain empty
2. Each box can have the number 1 typed into
Is this possible with JS and, if so, how do I do it??
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!

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.

View 2 Replies View RelatedI 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.

This is an assignment I have for a course I am taking. The objective is to validate the zipcode of a form to ensure that it only contains numbers. I cannot get this to work. The teacher wants us to use the for loop to do this, otherwise I would use a different function.

I was wondering if it is possible to validate tex boxes and check for numbers etc..

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.

The above code was copied from a Youtube tutorial about JavaScript.
I would like to ask, what additional code should be added in the existing code in order to validate the numbers only and an email format before the form to be submitted?
I need a regular expression to validate a string which consists of numbers, seprated by a period. For example: 123.456.7890.123 or
543245634.564362454.543543523.43532543
Basically, its a set of any amount of numbers, seperated by a period, ocurring any number of times. Now this is my first time dealving into regular expressions, and after reading some tutorials i came up with this:
/+((+d).)/
Would this evaluate correctly?
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..
I'm creating an online enrolment form for my company, who are a training company. Users enrolling on the course must make three choices - The level of course, the size of course and whether they wish to attend a workshop or study by distance learning. The combination of these three factors will determine the price. I'd like to have the price automatically calculated using javascript and displayed on the form before they submit. Can anyone give me an idea of how to do this?There are three drop down boxes for users to select their course. They are: -
Level of Qualification:
Level 3
Level 4

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);
I want to select numbers from a list box and add it to a text box with comma separated. my java script code does not work into browser but work fine into eclipse jsp view.
function passingNumbersToTextArea(numToCall,allNum)
{
var numFromList=document.getElementById(allNum);
var numToTextArea=document.getElementById(numToCall);
if(numToTextArea.value.search(numFromList.value)!=-1)//if duplicate Number is exist
{
alert("Duplicate Number Can not be added :");
return false;
}
else
{
if(numToTextArea.value.length!=0)
{
// If textarea has value than it added another value with comma seperated
numToTextArea.value=numToTextArea.value+','+numFromList.value;
return false;
}
else
{
numToTextArea.value=numFromList.value;
return false;
}
}
}
jsp code
<h:inputTextarea cols="10" rows="4" id="numberToCall" required="true"
value="#{conferenceCall.numberToCall}" styleClass="form_input_box" />
<h:selectOneListbox styleClass="form_selectmenu" id="allNumbers" size="5" onclick="passingNumbersToTextArea('numberToCall','allNumbers');">
