I have an input text box in my HTML form which looks for a regex pattern as shown below.
I am looking for anything to be entered other than white spaces or blank. I tried all the following below and none of them is allowing me to enter any normal text such as "hello world" and "helloworld" in it.Any suggestions are most welcome. Thanks
<input name="item" type="text" size="25" autofocus="autofocus" pattern="^\S$" title="Enter something valid"/>
<input name="item" type="text" size="25" autofocus="autofocus" pattern="^[^\s]*$" title="Enter something valid"/>
<input name="item" type="text" size="25" autofocus="autofocus" pattern="^[\S]*$" title="Enter something valid"/>
EDIT:
after removing the anchor, this works for "helloworld" but not for "hello world". So I think it has to do with regex pattern.
<input name="item" type="text" size="25" autofocus="autofocus" pattern="[^\s]*" title="Enter something valid"/>
[^\s]* will match against anything that contains no spaces, so a space in the words will not match.
You probably want something like .*[^\s].* to match a string with at least one non-space character.
The required attribute is probably the best way to guard against blanks (or ^$ should work).

I'm trying to limit my text input to only allow letters, not numbers. With a maximum of 100 characters. I'm having trouble finding out how to use the pattern attribute to only allow letters. Here is a portion of my code attempting this.
<form action="http://www.severien.com/grit/formecho.php" method="post" target="_blank">
<label for="videorequests"> Video Requests:</label>
<input type="text" id="videorequests" name="videorequests" maxlength="100" pattern="[a-z]{1,100}" />
<input type="submit" value="Submit" class="submitbutton" />
</form>
Using the attribute maxlength I'm limiting the character input to 100. How do I use pattern to limit the character use to only letters, excluding numerical characters?
use this
pattern="[A-Z a-z]{1,100}"
I'm trying to figure out a pattern regex for credit card expiry date input that would return mm/yy
currently I came across yyyy-mm-dd pattern represented like this:
<input type="text" pattern="(?:19|20)[0-9]{2}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))" />
That I tried to edit, but I can't seem to get it right for mm/yy
If you use this pattern, user couldn't enter invalid months number like "34" - first number has to be "0" or "1". "/" is not optional here.
Also "title" can help user to enter valid code sending additional message in tooltip.
<form>
<input
type="text"
pattern="(?:0[1-9]|1[0-2])/[0-9]{2}"
title="Enter a date in this format MM/YY"
/>
<input type="submit">
</form>
Try with this regex, it should work:
<form>
<input type="text" pattern="([0-9]{2}[/]?){2}" />
<input type="submit">
</form>
It matches two({2}) digits([0-9]) plus an hypothetical "/"([/]?), all this two times.
The first one it will match "mm/", then just the "yy" part.
Hope it helps!
I have about 1,000 lines of html that look like this:
<input type="text" readonly value="some-value-here" class="unit size1of2" />
I am able to find all of those lines using the RegEx search of
<input type="text" readonly value="[^<]+" class="unit size1of2" />
However, I am trying to change all of them to
<input type="hidden" value="same-value-that-was-found" />
Any ideas on what I need to do to accomplish this?
I'm using HTML5 form validation on the frontend to provide users with some feedback when they exceed a character limit in an input.
<input id="description" placeholder="description" required="required" type="text" pattern=".{3,500}">
This, with some CSS, will let me tell the user if they have not entered between 3 and 500 characters.
How could I actually set the pattern to match the number of "words" instead of characters .e.g. minimum of one word and max of 50 words.
This regex should work, the first clause (\w+\W+){0,49} will match between 0-49 words (of one or more characters) followed by one or more whitespaces. The second part \w+\W* will match one more word with optional whitespace following.
<form>
<input id="description" placeholder="description" required="required" type="text" pattern="(\w+\W+){0,49}\w+\W*">
<input type="submit" />
</form>
I am trying to search a string in eclipse.
<input type="text" autocomplete="off" />
<input type="text" sacsacdfsre />
I want to search all input elements of type text and exclude elements with autocomplete.
Search input and text and exclude autocomplete
I am trying
input.*text.*^(autocomplete)
how can we solve this.
Try something like this:
<input[^>]+type="text"(?![^>]*autocomplete).*?>
