I'm using an input type="number"to allow users to put a duration time on a post. The format is days hours:minutes:seconds as the backend provides the format.
What I need to do is to give that format to the input. Is this possible?
You can use input type text with pattern:
<form>
<input type="text" pattern="^\d{1,3} \d{1,2}:\d{1,2}:\d{1,2}$" placeholder="days hours:minutes:seconds"/>
<input type="submit"/>
</form>
It will validate the text using 1-3 digits for days and 1-2 for hours minutes and seconds.
You can also restrict typing of no digits and colons and space using jQuery:
$(function() {
$('input').keydown(function(e) {
console.log(e.which);
if (!((e.which >= 48 && e.which <= 57) || (e.which == 186 && e.shiftKey) || e.which == 32)) {
return false;
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="text" pattern="^\d{1,3} \d{1,2}:\d{1,2}:\d{1,2}$" placeholder="days hours:minutes:seconds"/>
<input type="submit"/>
</form>
If you have jQuery, then take a look at:
http://jonthornton.github.io/jquery-timepicker/
you can use also
<input type="datetime">

I have this HTML text input as below
<label style="color: white;" for="id">ID:</label>
<input type="text" onkeypress="return event.charCode >= 48 && event.charCode <= 57" maxlength="9" name="id" id="id">
Now, in the onkeypress I successfully added so only numbers can be entered.
but I have a JavaScript function called:
function checkID() {
and I want that additionally, after every number entered it will call this function. But I just can't get it to do them both (only allow numbers and call the function).
Thanks in advance! Itay.
You can enter the number validation to the checkID function.
<input type="text" onkeypress="return checkID(event,this)" maxlength="9" name="id" id="id">
function checkID(e,elem) {
if !(e.charCode >= 48 && e.charCode <= 57)
return false;
// continue checking the id...
}
Alternatively to attaching your function via html, you can add it using purely javascript:
document.querySelector("your-html-selector").addEventListener("keypress", function(event) {
// all your code here
});
This keeps your html clean and your code easy to read, especially if you're trying to execute multiple functions and such on an event occurring.
I have an input text box to fill in with hours from 00:00 to 23:59
I'd like to dynamically insert the double point ":" after the 2 first characters, something like in http://www.railtime.be/website/home-fr which is even giving an error message when wrong hours are given like 30:66... I can't figure out how it has been done, any idea?
<input type="text" name="time" id="time" placeholder="00:00" maxlength="5" value="">
I think a keypress function has been used but what with?
Thanks in advance!
Resolved with dfsq solution:
$('input#time').on('keyup', function(e) {
if (e.which && this.value.length === 2 && e.which !== 8) {
this.value += ':';
}
});
<input type="time"> isn't supported in Firefox etc.
If you wish to avoid jQuery, just use this simple code wherein your ':' would be inserted at the time of typing itself using the keyup event-
<html>
<head>
<script type="text/javascript">
function insertColon(e){
var unicode=e.keyCode? e.keyCode : e.charCode
if(unicode!=8){// this avoids backspace to spoil your logic
var textval=document.getElementById("time").value;
if(textval.length==3&&textval.charAt(1)!=":"&&textval.charAt(2)!=":"){// this case arises when backspace is used
textval=textval.substring(0,2)+":"+textval.substring(2,3);
document.getElementById("time").value=textval;
}
else if(textval.length==2&&textval.charAt(1)!=":"){// normal case
textval=textval+":";
document.getElementById("time").value=textval;
}
}
else if(unicode==46&&textval.length>=3&&textval.charAt(1)!=":"&&textval.charAt(2)!=":"){
textval=textval.substring(0,2)+":"+textval.substring(2);`document.getElementById("time").value=textval;`
}
}
</script>
</head>
<body>
<input type="text" name="time" id="time" placeholder="00:00" maxlength="5" value="" onKeyup="insertColon(event);">
</body>
</html>
You can yourself add some little code to script to check if the ranges of hours and minutes are falling within range.
This may help you out. http://jsfiddle.net/e2DzT/380/
It checks for the correct format, and if it is empty. It will output the correct response. Format can be only in 15:30 format.
When the correct format is found, the form is submitted.
<form id="login" name="login" method="post" action="#">
Just change it to what you want it to do.
You can try the following Javascript code:
function appendColon(){
var time=document.getElementById("time").value;
var hours=time.substring(0, 2);
var minutes=time.substring(2, 4);
document.getElementById("time").value=hours+":"+minutes;
}
<input type="text" name="time" id="time" onchange="appendColon()" placeholder="00:00" maxlength="5" value="">
In the onchange event of the input, appends : between hours and minutes.
I have a form which for now is only accepting integers, how can I have a form which accept decimals?
Also how can I activate a keyboard in HTML that has a keypad and a decimal point?
My JavaScript code for now is this:
var peso = parseInt(form.elements["x"].valueAsNumber);
var eta = parseInt(form.elements["y"].valueAsNumber);
var creatinina = parseInt(form.elements["c"].valueAsNumber);
and for the variables in HTML form, this:
<p align="center" style="font-size:20px">Peso (kg)</p>
<input name="x" type="number" value="70" style="width:100%;height:40px;font-size:15px;" pattern="\d*"/>
The way to handle it is to use an <input type="text"> and add a proper javascript-match.
<input type="text" name="amount" id="amount" maxlength="6" autocomplete="off"/></span>
After any change in this field happened, you could check against a regular expression like that one:
var ok = /^\d*\.?\d*$/.test(input);
If you think the input is correct, everything is fine. If not, you can print a message that this box should accept a decimal.
try this one to make you textbox able to accept only Numbers and decimals.

I'm having two text boxes to store two dates. I want to call a javascript function upon entering date into the first and second textbox. That is as soonas I enter the date in second box I want to call the javascript function. I tried onchange but it is not calling the javascript function. Can you suggest me the right event to call the javascript function? Thanks in advance. I'm using smarty. My code is as follows:
<label>Created Date From</label>
<div class="form-element">
<input type="text" class="cal fl-left" name="from_date" id="frmDate" value="{if $data.from_date}{$data.from_date}{else}{/if}" maxlength="10" />
</div>
<label>Created Date To</label>
<div class="form-element">
<input type="text" class="cal fl-left" name="to_date" id="toDate" value="{if $to_date}{$to_date}{else}{/if}" maxlength="10" onchange="get_tests_by_date(); return false;"/>
</div>
Javascript code is as follows:
function get_tests_by_date() {
document.location.href = "view_tests.php?test_category_id="+document.getElementById('test_category_id').value+"&test_mode="+document.getElementById('test_mode').value+"&test_type="+document.getElementById('test_type').value+"&package_type="+document.getElementById('package_type').value+"&created_date_from="+document.getElementById('frmDate').value+"&created_date_to="+document.getElementById('toDate').value+"&page=1";
}
This is what i ended up doing years ago, no jquery in this code:
HTML:
<input name="FormStartDate" value="" maxlength="10" onkeydown="KeyDateNumCheck()"/>
<input name="FormEndDate" value="" maxlength="10" onkeydown="KeyDateNumCheck()"/>
JS:
//do not allow to input anything except the numeric characters, dashes, or slashes
function KeyDateNumCheck()
{
var iKeyCode = event.keyCode;
if ( (iKeyCode != 109) && (iKeyCode != 189) && (iKeyCode != 111) && (iKeyCode != 191) &&
( ((iKeyCode > 57)&&(iKeyCode < 96)) || (iKeyCode > 105) || (iKeyCode == 32)) )
event.returnValue = false;
}
I experience strange problem in addition to all my other problems. I am creating ASP.NET MVC application. I am using a flexigrid and attempting to use Modal dialogs. In IE, Google Chrome and Opera I can type numbers only in the Client No control, but in the FireFox I am unable to type anything.
This is how that controls renders:
<div id="add-edit-dialog" class="ui-dialog-content ui-widget-content" style="width: auto; min-height: 0px; height: 622px;" scrolltop="0" scrollleft="0">
<form id="add-edit-form" novalidate="novalidate">
<fieldset>
<legend>Client Info</legend>
<input id="fntype" type="hidden" name="fntype" value="">
<input id="ClientId" type="hidden" value="" name="ClientId" data-val-number="The field ClientId must be a number." data-val="true">
<div class="editor-label" style="background-color: rgb(255, 255, 255);">
<div class="editor-field" style="background-color: rgb(255, 255, 255);">
<input id="ClientNumber" class="numericOnly input-validation-error" type="number" value="" name="ClientNumber" data-val-required="The Client No field is required." data-val-remote-url="/Client/doesClientNoExist" data-val-remote-type="POST" data-val-remote-additionalfields="*.ClientNumber,*.ClientId" data-val-remote="Client Number already exists. Please enter a different Client Number." data-val-number="The field Client No must be a number." data-val="true">
<span class="field-validation-error" data-valmsg-replace="true" data-valmsg-for="ClientNumber">
I am using my own class numericOnly and type number (which displays as spinner in Google Chrome).
I have CardNumbers.js file where I define numericOnly class this way:
$(".numericOnly").keypress(function (e) {
if (String.fromCharCode(e.keyCode).match(/[^0-9]/g)) return false;
});
The code above I found a while ago in one of the StackOverflow questions and it works Ok in other browsers.
So, do you see what may be wrong here and why I can not type anything but in FireFox only?
Try this solution. I hope this is what you are looking for.
Just change
from
if (String.fromCharCode(e.keyCode).match(/[^0-9]/g))
to
if(String.fromCharCode(e.which).match(/[^0-9]/g))
Try This:
$(document).ready(function() {
$(".numericOnly").keydown(function(event) {
// Allow: backspace, delete, tab, escape, and enter
if ( event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
// Allow: Ctrl+A
(event.keyCode == 65 && event.ctrlKey === true) ||
// Allow: home, end, left, right
(event.keyCode >= 35 && event.keyCode <= 39)) {
// let it happen, don't do anything
return;
}
else {
// Ensure that it is a number and stop the keypress
if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105 )) {
event.preventDefault();
}
}
});
});
This sounds like more of a browser issue. If your Firefox is out of date, try updating through Help > About or at http://getfirefox.com/. I just took it to an HTML testbed in Firefox v18 (latest on release channel), and it worked fine.
