JQuery :: Prevent User From Adding More Characters Into A Text?
Jul 2, 2009is there a way to prevent user from adding more characters into a text input based on a validation rule(eg. you entered more than n words, you can't enter more, but you can delete or edit)? I think I'll have to programmatically delete the extra letter(s) that user just input somehow if the addition causes a violation of the rule, is this the best way?

Check If Field Is Numeric, But Allow Certain Characters..?
Oct 12, 2006I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?
JQuery :: Prevent A Particular Field Being Submitted In Form Submission
Jun 1, 2009I have email, password and some other fields, and I'm using $.post to send data.
In Ajax form submission, I don't want to submit a particular field. The serializeArray() method returns all the fields in the form. So, I tried something like this to prevent the password field being serialized.
This works great but the ajax submission doen't work.
Test A Field For Valid Characters Using REGEX?
Dec 7, 2010I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
Code JavaScript:
if(document.getElementById('RegisForm_Username').value == /[^a-zA-Z 0-9]/g)
{
your username must be alphanumeric (consisting of the letters A-Z or numbers 0-9) and cannot have any special characters.");return false;}
Setting Text Field To Accept Only Alphabetical Characters?
Oct 26, 2008I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

Jun 14, 2011I am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
Removing Unwanted Characters From A Passed Value And Passing To Input Field
Oct 20, 2009I have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?

Prevent "Enter" On A Text Field From Submitting A Form.
Jul 23, 2005Is there a way to prevent a form submitting when you press enter on a text
field? Some people press enter when they finish typing in a text field out
of habit I guess unconcsciously thinking it will take them to the next
field. Instead it submits the form and this causes all kinds of problems in
my case. Any javascript solution?

Possible To Prevent Highlighting Text Within A Text Field?
Oct 26, 2002I am using a calendar control based on the one at Brainjar.com. I have made the text field into which the date is inserted readonly. The problem with this is that if a user attempts to change the date manually by deleting part of the highlighted text, the browser goes back one page.
I want to force the user to use the calendar control and not input text directly into the textfield- readonly is not enough as the text can still be highlighted and then causes problems if the user attempts to delete.

JQuery :: Detecting Field Value On Page Load And Clearing Field Label
Oct 14, 2010I'm having trouble detecting if there is value in a field when the page loads and manipulating the fields label class accordingly. Below is my code. I'm using it to display the field label inline with the field, and when the user starts typing, the label is hidden. The problem I'm having is, since this is for a login screen, if the user has typed in an incorrect password, the username still remains entered when the page reloads and I see my label stacked underneath.
How can I detect if that field has a value and apply a class to the label to hide it? I don't have to have to specify each field by their ID, because I'd like to use this all over (member profile management area).

JQuery :: Replace Dots And Commas In A Field And Then Use That Value To Auto Populate Another Field?
Oct 27, 2010I'm using Google Maps to calculate distance between cities. I need to use that distance value for some basic calculations. Distance has to be in "Angloamerican" format (1,234.00) but in metric system. So, Google Maps answer for Madrid - Berlin query will be one of these two:
a) <span jscontent="distance['text']" jsdisplay="distance" jstcache="7">2.320,1 km</span>
b) <span jscontent="distance.text" jstcache="23">2.320,1 km</span>
notice the differences in span "classes" (jstcache is 7 or 23) and lack of any "id" or "name" attributes.
What I want to accomplish is:
1) Convert these Google Maps distance values to "Angloamerican" format (2,320 km) or (even better) format without thousands separator which would only use dots as decimal separator (2320.1 km)
2) Use that filtered value to populate a text field called distance
Populate hidden form element value with the value of a text field on form submit (jQuery)

Form Validation Field Values Not Saved If One Field Is Not Completed/invalid?
Feb 3, 2009The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,

How To Prevent Div From Resizing
Dec 10, 2005i have a div, i set the innerHTML property to a formatted paragraph of
text. however, at times the text exceeds the width (and height) of the
div. how do i create a fixed width div and make it use a scrollbar if
the contents exceed the height and width specified. i'm using microsoft
visual studio, and i have the width explicitly set in the properties
but still on setting the innerHTML it resizes automatically.
Prevent Paste
Sep 29, 2007I found this handy little script on the net that means the user can only press backspace or numbers in form input.
<script type="text/javascript">
function numbersonly(e){
var unicode=e.charCode? e.charCode : e.keyCode
if (unicode!=8){ //if the key isn't the backspace key (which we should
allow)
if (unicode<48||unicode>57) //if not a number
return false //disable key press
}}
</script>
<form>
<input type="text" size=18 onkeypress="return numbersonly(event)">
</form>
It works, but it's not foolproof.
2 issues with this code.
1) Can I stop a user from accessing my website if he/she is not using
javascript?
2) Can I prevent a user from breaking the code and entering other
stuff by placing the cursor in the box and pressing ctrl+v (paste)

Dec 24, 2010So, I have a set of divs in a sentece, and within one div is a link. When the link is clicked, I have all the other divs fade out, and the link is supposed to move to the left, then up. I can accomplish this easily, however, I've noticed that there's a pause between when all the divs fade out, and then the moving of the link. During that pause, it jumps to the leftmost edge of the div that it is contained in.Is there a way to prevent the div from jumping? The following is the code that I have.
