Tell me how to check the value of a textbox in a form,
1, the value must be only a positive number ( not 34ax43) , for input a stock number of product
2, the value must be positive komma and two digits max (eg 150,20) , for input price value
What I want to do is to check if the selected date in a form textbox is less than today in which case an error message should be displayed. I tried to write the code myself, but unfortunatelly I miss something.Here are th lines:
Code:
function dateValidation()
{
var obj = book.dc1.value;
var day = obj.value.split("/")[0];
var month = obj.value.split("/")[1];
[Code]...

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

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.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
I have a text box and would like to see if the value of the input matches the values defined in a JavaScript array.[code]...

How to check if the textbox value has been changed in the button onclick event?
I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
Basically, i have a past and present checkbox, start date and leave date. Now if the user clicks on the "present" checkbox i want the leave date checkbox to vanish and if clicked again i want to re-appear..Take a look at this page:-http:[url].....
now you can see at the moment i have the checkboxes past, present and 2 text boxes beneath. Can i do this?
I am new to jQuery, and learning more about Js by doing. I can hand-code HTML and CSS very well and understand OOP effectively. However, troubleshooting complex Javascript code combined with jQuery is a challenge to me, but I really want to learn. I am using Windows XP Professional and IE 8, FF 3.6.

Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.

View 4 Replies View RelatedI currently have a form named "survey". I found here a JavaScript to validate my form.
I am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.

View 7 Replies View RelatedI want to get the code ( I cant write it Im still a newbie ) to check a form user/pass and trigger another hidden form.
Heres what going on:
Have created a form, Form 1 Login: it has a username and pass fields. It shares the page with a Members Login form.
I want javascript to check the user/pass on Form 1 Login against a user/pass I assign. I assume I can assign one in the Javascript code.
The script does not send the form to the server, it just checks to see that the user/pass agrees with what Ive assigned.
The script, if the user/pass is the same as I assigned, triggers a Registration form to pop up that Ive hidden with CSS left:-999em.
Now the script has fulfilled its function, its done. But heres what continues and Adobe BC does this part.
User fills out the pop up Registration form with any user/pass, their valid email and name.
Clicks Submit and the form sends the New user a new personal pass and new username via email.
User adds New user/pass to Members form and is allowed into the site.
This is a round about way but, I can not use php or server side in this process, BC does not allow server side only client side. So Im doing a work around. I know someone could find the Javascript even in a js folder. Tight security is not an issue. I researched this for weeks and BC tells me it will work with their system...I just dont know how to write it.
I have a form that contains multiple textboxes and that are labeled based on their location in a table (ie. 0,0 0,1 1,0 1,1, etc.).I want to use a javascript that will automatically update the value of that box into a database when that textbox is left (onBlur).How can get I get the name of the textbox that the user was just on without knowing specifically which one it was? with that i can grab the value and go from there, but i don't know how to get started here...Sample of what I'm working with:

I'm new at Javascript, short of some modifying. I'm trying to figure out how to make this work. I want the user to enter a page number into a textbox, and go to a page in a PDF catalog after the 'submit' button is clicked. Its easy to link to certain pages in a PDF, I just want the user to be able to insert a number into a textbox and form the link based on that value. Something like:
<a href="www.mysite.com/document.pdf#page=TEXTBOXVALUE">
I want to get the value of a textbox into php without clicking the submit button. Here is what I have My form field:
#1
<input type="text" style=background:transparent; border:0px; name='clientid' >
This field is populated dynamically by its name with another php script in this way
#2
echo "formObj.clientid.value = '".toSafeString($inf["clientID"])."';
";
Now I want to take the value in code#1 (name='clientid') and pass it to a php code that is in the same file as the form. Here is the php code
<?php
$name=$_POST['name'];//this is where the value of the text box mentioned is defined
include 'datalogin.php';

I know this may require js

I am messing with this whole day, 'cos I wanted to try and figure this out by myself instead of going on forums.I failed, as you may see. So, to cut it short:I needed to calculate my prices on-the-fly and display it in textbox with javascript.Well I did succeed with values of radio button an checbox, but as i know very little javascript, I don't know how to expand the code i got from here:http://javascript.internet.com/forms/update-order-form-no-page-refresh.htmlSo what I would LOVE to know, is how can I make this happen:I have a textbox:<input type="text" name="podstranice" size="19" lass="podstr"nkeyup="this.form.total.value=calculateTotal(this);">and when a user inputs a number in it, javascript multiplies it with some other number, say 10 (its a price*quantity thing) and adds it to the total price along with data from checkboxes and radio buttons.And so, this is my javascript. It is basically identical to one on the link, but you can view it better this way I think.
// Calculate the total for items in the form which are selected.
function calculateTotal(inputItem) {
with (inputItem.form) {

I have a form which i want to calculate entered values in text boxes. What i want from the below code is ;
1- i may have 100 textboxes so the javascript that i use may be inefficient for larger amounts. Does anyone have more encapsulated solution for multiplying and adding to total amount?
2- when i click check boxes their values must be added to total textbox below.
3- How can i calculate VAT and grand total? with $ sign infront of them ?
its seems easy but couldn't manage to do as i am not a programmer.
I have this, VB.Net code..how can i do exact same thing in javascript?

Say I have a simple page with a top and bottom frame. The top frame has a form (named "form1") with a single textbox entity in the form.How does the bottom form get the contents of that textbox using javascript? Specifically with Internet Explorer 8?I've tried every rendition that I know of.I have to admit that javascript isn't really my forte.I thought a line like:
Code:
value = top.frames[0].document.form1.mytextbox.value; would work, but it is not.
