I have a school project and I need to make a website where I can add more balance to my account. But I can't figure it out.
I would like to make an HTML number input and then that input needs to add up with my existing balance. But I can't make it work
This is the code I have:
<fieldset>
<legend>Opwaarderen</legend>
<input type="number" id="opwaarderen">
<input type="submit" onclick="opwaarderen()">
</fieldset
But how can I make the Javascript function? So that the input will add up to my already existing balance.
This will help
var currentCredit=0;
$("#a").click(()=>
{
alert(currentCredit+=Number($("#opwaarderen").val()));
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<fieldset>
<legend>Opwaarderen</legend>
<input type="number" id="opwaarderen">
<input type="submit" id="a">
</fieldset>

I have work on a project to used the mask of cnic and mobile for Pakistani format.
The format of CNIC is : XXXXX-XXXXXXX-X
The format of Mobile is 03XX-XXXXXXX
CODE:
$('#CNIC_No').mask("99999-9999999-9");
Please try this code,
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/3/jquery.inputmask.bundle.js"></script>
<input type="text" data-inputmask="'mask': '99999-9999999-9'" placeholder="XXXXX-XXXXXXX-X" name="cnic" required="" >
<input type="text" data-inputmask="'mask': '0399-99999999'" required="" type = "number" maxlength = "12" >
<script>
$(":input").inputmask();
</script>
numeric keyboard instead of alphabetical:-
this.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
in the file MaskedEditText.java. Now setting android:inputType = "numeric" will work.
Thanks

i just want to paste the content of one textbox to other when i click the button u . but it is not showing.
<html>
<head>
<script src="jquery_min.js">
</script>
<script>
$(document).ready(function(){
$("#button").click(function(){
var ravi=$("#text").val();
$("$text1").val(ravi);
});
});
</script>
</head>
<body>
<input type="text" value="ravi" id="text">
<input type="text" id="text1">
<input type="button" value="u" id="button">
</body>

You need to use # to target element by id in jQuery, so change:
$("$text1").val(ravi);
to:
$("#text1").val(ravi);

So here is my site: http://dll-download.us/
I want it where if someone clicks on "Can't Find a File?", I want it to instead select the search box so they can search for it instead.
Code of search box on my site:
<form method="get" action="/search" id="search">
<input name="q" type="text" size="40" placeholder="Search for a DLL" />
</form>
The easiest way to do this would be to add a click event to the can't find a file link, then use JavaScript to focus the text box.
function setFocus() {
document.getElementById("myTextbox").focus();
}
