What I want to do is make it so that when a user inputs these values PIV13RT, PIV13RT2, PIV13RT3 into a text box, it will recognized. The problem is that you're able too input PIV13RT1, because the one is already present - which I don't want to be the case. Is there anyway to stop this? Thanks. Take a look at my code.
Basically, It's been tested and everything else seems to work. It's just it sees PIV13RT1 as a value when it souldn't be.
<form>
<input type="text" id="modlenumber" pattern="^[PIV13RT2-3]+{7,8}$" title="Your
Model Number." placeholder="Please Input a Modle number" size="35"
maxlength="8"><input name="" type="submit" />
</form>
Does this pattern work for you?
^DIV13RT[23]?$
You wrapped the text you're searching for (DIV13RT) with a square brackets. They're used to match any of the containing characters so it matched every value which has at least "D" or "I" or "V" or "R" or "T" and so on.

So I'm trying to make a form for my assignment, and I am using the pattern attribute in html so only certain characters are required to be typed on the text box. But for some reason, the form is saying using that I'm using an incorrect format even though I made my pattern attribute that way.
Here's an example of the code and a picture of the problem.
<form>
<label for="mnumber">Mobile Number:</label>
<input type="text" required id="mnumber" pattern="[0-9]"><br><br>
<input type="submit" value="submit">
</form>
You did write:
pattern="[0-9]"
You are asking for only one number. You just forget to add '+' to accept more than one number. I guess what you are searching for is this:
pattern="[0-9]+"
pattern="[0-9]"
allows for only a single number character to validate (and be submitted). If you want to allow more than one character, here's your options:
One or more numbers:
pattern="[0-9]+"
Zero or more numbers:
pattern="[0-9]*"
One to three numbers:
pattern="[0-9]{1,3}"
you just need to change type="text" to type="number"
Would like a HTML number field where the user can enter numbers separated by commas and spaces... like '1, 2, 3.' Right now it only accepts inputs without commas and spaces and won't let me submit the form with commas/spaces in the field.
Here's a sample of my simple input field now:
<input id="A" name="HLA-A" type="number" />
Need number field so number keyboard will pop up on smart phones.
Did a good bit of looking and I'm surprised I didn't find anything on this... perhaps there is a simple answer? Anyone have any ideas?
Thanks!
If you REALLY need type="number", then you should do as follows:
<input type="number" />,<input type="number" />,<input type="number" />
Otherwise, you could do as follows:
<input type="text" pattern="\d+, \d+, \d+" />
Both ways, some browsers may not support it.
I want an input that it can only enter exactly N quantity of numbers , no less, no more.
I have tried this:
Example with 4 digits.
<input type="text" name="myinput" pattern="[0-9]{4}" title="Only four (4) digits.">
But it does not work, someone knows how to fix it?
By "it does not work" I assume you mean the pattern isn't checked when the input is empty. Otherwise there doesn't seem to be anything wrong with the pattern.
That is how the pattern attribute works. You'll have to add required as well if you don't want to allow empty input.
<form>
<input type="text" name="myinput" pattern="[0-9]{4}" required>
<button type="submit">Submit</button>
</form>
I want to prevent the user from entering non-numeric characters in a textfield for telephone number in HTML5. I tried this, but it doesn't forbid non-numeric characters:
<input type="tel" name="usrtel"><br>
I tried using type=number as well, but that gives me a up and a down arrow to increase or decrease the value, which is not useful for telephone numbers. How can I accomplish this?
You can use pattern attribute with a regex \d*
<input type="tel" name="usrtel" pattern="\d*" />
Demo (After typing in the box, just click anywhere outside the box, if you type in anything except the integers, it will show a red box, else it will stay normal)
Demo 2 (With custom message and submit button)
As you commented, you can change your pattern value to ^[0-9]{3,45}$ where user will have to input minimal of 3 digits to maximum of 45 in length.
Demo
<input
type="tel"
name="usrtel"
pattern="^[0-9]{3,45}$"
title="You can only enter numbers, with a minimal of 3 characters
upto 45 characters are accepted."
required="required"
/>
In the above markup, am using a title which will throw a custom error to your user.
I have never seen this, have no idea what is going on:
<form action="/cgi-bin/Lib.exe" method=POST name="slider" ID="Form2">
<input type="text" name="user" value="" ID="Text1">
<input type="text" name="end" value="" ID="Text2">
</form>
function setval()
{
alert(s.getValue());
alert(s2.getValue());
document.slider.user.value = s.getValue();//set value of hidden text box to value of slider
document.slider.end.value = s2.getValue();//set value of hidden text box to value of slider
document.slider.submit();
}
When submitting form from setval(), when I change the name of the first input box from "user" to anything else, my cgi application won't except it and I get an error? I can change the name of the secons input box to anyting and it doesn't seem to have any problem? Confused. Thanks!
Seems more like it's a problem with the cgi than it is with the HTML/Javascript, to me. It probably makes the assumption that a value for "user" will always be sent. Not much else I can tell you without seeing the form-processing code.
Your CGI must be expecting an element called 'user'. You would need to check the source.
