I want the javascript to test an alphanumeric (a string contains alphabet or numbers only) string. Should I write a regular expression?

text box. If the user enters non-alphabet or non-numbers, I should pop
up a message and doesn't allow the user to do that. I am using regular
expression to do the checking. But it seems it always return false...

View 2 Replies View RelatedI have a form and I need to validate a field against three rules:
1) The field need to be between 6 and 12 characters
2) It can only have letters, numbers, and the underscore
3) It cannot contain a space or other special characters
I want the validate to happen in real-time. I have the first rule working great. Here is the code for that:
var username = document.getElementById('registerUsername');
if((username.value.length < 6) || (username.value.length > 12))
{
document.getElementById('usernameValidate').innerHTML="Incorrect.";

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.

The 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,
function validate_form ( )
{
valid = true;

What happens is that when I click on a button, a random string from the RandomString variable appears below the button. e.g I click on the button and it displays 'AAB' and then if I click on the button again it may display 'AAE' and etc.
The problem is that sometimes it displays 'undefined'. I don't wanit 'undefined' to appear but why does it sometimes display 'undefined' rather than a Random string.
Below is the code:
JavaScript Challenge Play--Random Color (The English Version of JavaScript)
Write a function to return a string that can represents a color.
Requirements:
1. The color is random. The color string can be similar to "cf9c63", also similar to "rgb (211,100, 180)".
2. Code should be concise, clear, easy to read, good performance, and better than my solution.

my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:
//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()
function validate_join()

I have such a text
<input type="text" name="search_txt" value="">
<textarea name="txt_m">

My hobby is driving a car.

I would like to bold and color a specified text
in input field search_txt for instance "hobby" string.
How to do that in JS?
How to check that a text field is a string not a number with javascript? Therefore,if the field is a number then I want to display a message that contain "You must enter a string".
var str = champ.value;
if (!(isNaN(str))) {
alert("Vous avez saisi un nombre");
I tried the previous code but it does not work.
so I have a widget that will let you get alerts texted to a phone. I am trying to store the info, but I can't get the user's input into my javascript function shown below:
onClick="collect('info', 'nname=' + document.getObjectByID('Nname').value + ';num=12345;
How can I get the content as a string of a text field and use that in my function? Like I said, this is probably a relatively easy question for most, but I cannot figure it out :/
I'm trying to debug my expression that matches an alphanumeric with any
number of dashes (including none), except at the ends and obviously
disallowing two or more consecutive dashes.
Here it is: /w+(-?w+)*/
Test cases that I expect to pass are failing:
"01234abcdef" true
"0123-412-8370" false (should've been "true")
"asdkfjakfj" true
"0-1" false (should've been "true")
"-" false
"--" false
"-ABC123" false
"00230-" false
"ABC-123" false (should've been "true")
"1-" false
"111223333" true
Would anyone lend a hand?

Is there a way I can calculate a field in a form based on another field in
the same form. When clicking submit, both values should be posted to the
next page. I want to be able to type in a value in one field, and
automatically in a second field the value*1,36 should appear.
I have a site for property bookings with 2 calendars to enter start and end date. The calendar im using doesnt have any obvious facility to copy yhe date to 2 fields so each one has to be done, months in advance this can be a real pain.
Does anyone have any ideas how i can take the data inserted into one field and copy it to the second?
I am trying to find a way to get more than one characters pasted on html text field (input type=text), using onkeydown or onkeypress, I am NOT interested in onkeyup(it works), so please do not suggest me this solution. Also I am not interested in Jquery, I do not like to use it. I need solution to work with all browsers.
I am able to do that if you type one character, by taking the character of the event, but till now I am unable to get group of characters come from the paste (ctrl+V) or by mouse.You can look at Facebook search menu that shows auto complete results, it works on events: onkeydown and onkeypress and you notice that you get the result before you release your finger, try to paste something (more than one character) and you get the result before releasing finger, how? Onkeypress and onkeydown do not show first thing you paste or type because they happen before the text being added to text field.
Code:
<input type="text" id="targetTextField" onkeydown="CapturePastedString(this.id)" /> <script> function CapturePastedString(id){ var targetTextField=document.getElementById(id); // below I need to capture the pasted string like: var pasted_string= function(){.....} targetTextField.value=pasted_string; } </script>
sort Alphanumeric and alphabets present in the same column.Numbers should be sorted first,and then the words with number in the beginning should follow it and then words in the sorting order.
