HTML text input allow only numeric input
(78 answers)
Closed 3 years ago.
I'm making input that user could only type number or float number. If I type text it clears out whole input.I want forbid type text without clearing field . Any ideas how to make it?
<input
type="text"
id="willBeCreditedAmount"
maxLength={9}
placeholder="Enter amount"
pattern="[0-9]*"
onChange={(e) => this.props.updateWillBeCreditedAmount(e.target.value, currentComProfile)
}
value={willBeCreditedAmount}
/>
You can use this code
<form>
<input type="number" id="myNumber" value="1">
</form>
Try this
<input type="number"/>

How can I set an input element to be immediately ready for the user to type in, i.e, they do not have to click on the input to start typing, as soon as it renders, it displays the flashing vertical line and enables them to type straight away?
You can use autofocus (more info)
<form action="/action_page.php">
First name: <input type="text" name="fname" autofocus><br>
Last name: <input type="text" name="lname"><br>
<input type="submit">
</form>
You should use the attribute autofocus like in this example: https://www.w3schools.com/tags/att_input_autofocus.asp

I'm trying to make a text field I'm using get bigger when you add more characters to it, is there any way to do this?
I suprisingly haven't found a way to do this through searching.
For example:
<input type="text" name="firstname" value="John" size="1">
Would turn into
<input type="text" name="lastname" value="John Smith" size="4">
You could turn the <input> element into a <textarea>, then state how many rows and columns you want to have (basically height and width). In addition, the user can adjust it from there! If you're taking form data, it will still be able to be read. Just make sure that when you make the change remove the size=""
its should be adjusted when you enter more characters.
<input type="text" name="FirstName" onkeypress="this.style.minWidth = ((this.value.length + 1) * 7) + 'px';">

Is there a way to have a masked numeric input field?
(1 answer)
Closed 8 years ago.
I'm aware of this:
<input type="tel">
and I'm aware of this:
<input type="password">
But I would like to use both. I want the numeric keypad to come up on iOS (specifically) but hide each character after it's typed. Is something like this possible?
<input type="tel|password">
For iOS you can set the input to type "password" and still trigger the numeric-keyboard using the HTML5-Attribute "pattern":
<input type="password" pattern="[0-9]*" ... />
From the Apple-Documentation:
To display a numeric keyboard, set the value of the pattern attribute to "[0-9]" or "\d".
Html of input box:
<input type="tel" name="password" id="password" value="" placeholder="Enter password"
onfocus="changeToPassword()">
Javascript:
// change the type of the input to password
function changeToPassword() {
setTimeout(function () {
document.getElementById("password").setAttribute("type", "password")
}, 500);
}
this solution works on the iphone. This is kind of a hack. Once you have the number pad in the next 500 miliseconds you change the attribut to password and that tricks the phone.
You can make the input type password and then use javascript to validate that only numbers have been entered when the submit button has been pressed.
