JS:
<script type="text/css">
$(function() {
$('#upper').keyup(function() {
this.value = this.value.toUpperCase();
});
});
</script>
HTML
<div id="search">
<input type="radio" name="table" class="table" value="professor" tabindex="1" /> Professor
<input type="radio" name="table" class="table" value="department" tabindex="2" /> Department
<input type="radio" name="table" id="upper" class="table" value="course" tabindex="3" /> Course
<input type="text" name="search" class="keywords" value="Select an option..." onclick="this.value='';" onfocus="this.select()" onblur="this.value=!this.value?':this.value;" tabindex="4" />
<div id="content"> </div>
</div>
Why is this still not working?? Just trying to call div ".keywords" from JS.
This question is related to
javascript
jquery
I think the most easiest way to do is by using Bootstrap's class ".text-uppercase"
<input type="text" class="text-uppercase" />
<input id="name" data-upper type="text"/>
<input id="middle" data-upper type="text"/>
<input id="sur" data-upper type="text"/>
Upper the text on dynamically created element which has attribute upper and when keyup action happens
$(document.body).on('keyup', '[data-upper]', function toUpper() {
this.value = this.value.toUpperCase();
});
This answer has a problem:
style="text-transform: uppercase"
it also converts the place holder word to upper case which is inconvenient
placeholder="first name"
when rendering the input, it writes "first name" placeholder as uppercase
FIRST NAME
so i wrote something better:
onkeypress="this.value = this.value + event.key.toUpperCase(); return false;"
it works good!, but it has some side effects if your javascript code is complex,
hope it helps somebody to give him/her an idea to develop a better solution.
If you purpose it to a html input, you can easily do this without the use of JavaScript! or any other JS libraries. It would be standard and very easy to use a CSS tag text-transform:
<input type="text" style="text-transform: uppercase" >
or you can use a bootstrap class named as "text-uppercase"
<input type="text" class="text-uppercase" >
In this manner, your code is much simpler!
you can try this HTML
<input id="pan" onkeyup="inUpper()" />
javaScript
function _( x ) {
return document.getElementById( x );
}
// convert text in upper case
function inUpper() {
_('pan').value = _('pan').value.toUpperCase();
}
**JAVA SCRIPT**
<html>
<body>
<script>
function @ToCaps(obj)
{
obj.value=obj.value.toUpperCase();
}
</script>
<input type="text" onkeyup=@ToCaps(this)"/>
</body>
</html>
**ASP.NET**
Use a css style on the text box, write css like this:
.ToCaps { text-transform: uppercase; }
<asp:TextBox ID="TextBox1" runat="server" CssClass="ToCaps"></asp:Te writxtBox>
**OR**
simply write this code in textbox
<asp:TextBox ID="TextBox1" runat="server" style="text-transform:uppercase"></asp:TextBox>
**1.Note you don't get intelligence until you type up to style="**
onBlur="javascript:{this.value = this.value.toUpperCase(); }
will change uppercase easily.
try:
$('#search input.keywords').bind('change', function(){
//this.value.toUpperCase();
//EDIT: As Mike Samuel suggested, this will be more appropriate for the job
this.value = this.value.toLocaleUpperCase();
} );
Javascript has a toUpperCase()
method. http://www.w3schools.com/jsref/jsref_toUpperCase.asp
So wherever you think best to put it in your code, you would have to do something like
$(".keywords").val().toUpperCase()
Solutions using value.toUpperCase seem to have the problem that typing text into the field resets the cursor position to the end of the text. Solutions using text-transform seem to have the problem that the text submitted to the server is still potentially lowercase. This solution avoids those problems:
function handleInput(e) {_x000D_
var ss = e.target.selectionStart;_x000D_
var se = e.target.selectionEnd;_x000D_
e.target.value = e.target.value.toUpperCase();_x000D_
e.target.selectionStart = ss;_x000D_
e.target.selectionEnd = se;_x000D_
}
_x000D_
<input type="text" id="txtTest" oninput="handleInput(event)" />
_x000D_
Can also do it this way but other ways seem better, this comes in handy if you only need it the once.
onkeyup="this.value = this.value.toUpperCase();"
Javascript string objects have a toLocaleUpperCase()
function that makes the conversion itself easy.
Here's an example of live capitalisation:
$(function() {
$('input').keyup(function() {
this.value = this.value.toLocaleUpperCase();
});
});
Unfortunately, this resets the textbox contents completely, so the user's caret position (if not "the end of the textbox") is lost.
You can hack this back in, though, with some browser-switching magic:
// Thanks http://blog.vishalon.net/index.php/javascript-getting-and-setting-caret-position-in-textarea/
function getCaretPosition(ctrl) {
var CaretPos = 0; // IE Support
if (document.selection) {
ctrl.focus();
var Sel = document.selection.createRange();
Sel.moveStart('character', -ctrl.value.length);
CaretPos = Sel.text.length;
}
// Firefox support
else if (ctrl.selectionStart || ctrl.selectionStart == '0') {
CaretPos = ctrl.selectionStart;
}
return CaretPos;
}
function setCaretPosition(ctrl, pos) {
if (ctrl.setSelectionRange) {
ctrl.focus();
ctrl.setSelectionRange(pos,pos);
}
else if (ctrl.createTextRange) {
var range = ctrl.createTextRange();
range.collapse(true);
range.moveEnd('character', pos);
range.moveStart('character', pos);
range.select();
}
}
// The real work
$(function() {
$('input').keyup(function() {
// Remember original caret position
var caretPosition = getCaretPosition(this);
// Uppercase-ize contents
this.value = this.value.toLocaleUpperCase();
// Reset caret position
// (we ignore selection length, as typing deselects anyway)
setCaretPosition(this, caretPosition);
});
});
Ultimately, it might be easiest to fake it. Set the style text-transform: uppercase
on the textbox so that it appears uppercase to the user, then in your Javascript apply the text transformation once whenever the user's caret focus leaves the textbox entirely:
HTML:
<input type="text" name="keywords" class="uppercase" />
CSS:
input.uppercase { text-transform: uppercase; }
Javascript:
$(function() {
$('input').focusout(function() {
// Uppercase-ize contents
this.value = this.value.toLocaleUpperCase();
});
});
Hope this helps.
Here we use onkeyup event in input field which triggered when the user releases a Key. And here we change our value to uppercase by toUpperCase() function.
Note that, text-transform="Uppercase" will only change the text in style. but not it's value. So,In order to change value, Use this inline code that will show as well as change the value
<input id="test-input" type="" name="" onkeyup="this.value = this.value.toUpperCase();">
Here is the code snippet that proved the value is change
<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
<title></title>_x000D_
</head>_x000D_
<body>_x000D_
<form method="get" action="">_x000D_
<input id="test-input" type="" name="" onkeyup="this.value = this.value.toUpperCase();">_x000D_
<input type="button" name="" value="Submit" onclick="checking()">_x000D_
</form>_x000D_
<script type="text/javascript">_x000D_
function checking(argument) {_x000D_
// body..._x000D_
var x = document.getElementById("test-input").value_x000D_
alert(x);_x000D_
}_x000D_
_x000D_

</script>_x000D_
</body>_x000D_
</html>

I couldn't find the text-uppercase in Bootstrap referred to in one of the answers. No matter, I created it;
.text-uppercase {
text-transform: uppercase;
}
This displays text in uppercase, but the underlying data is not transformed in this way. So in jquery I have;
$(".text-uppercase").keyup(function () {
this.value = this.value.toLocaleUpperCase();
});
This will change the underlying data wherever you use the text-uppercase class.
