I have form fields such as <input type="text" placeholder="Name*"> . Then I have CSS applied to the placeholder, so it's grey. However, I want to change the asterisk(*) to be red. How would I target just that one character inside the attribute with jQuery or Javascript?
Here you go works for me
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<style>
input::-webkit-input-placeholder:after {
content: '*'; color: red;
}
</style>
</head>
<body>
<input type="text" placeholder="Name"></input>
<script>
</script>
</body>
</html>
So CSS only has ::first-letter and not ::last-letter styling... To make ::first-letter apply to the last letter, you do a trick by changing the direction of the text like so:
::-webkit-input-placeholder {
unicode-bidi: bidi-override;
direction: rtl;
text-align: left;
}
::-webkit-input-placeholder::first-letter { /* WebKit browsers */
color: red;
}
The issue with this is that you'll need to reverse your placeholder attribute and you can't use an asterisk because that's considered punctionation. But you can use unicode characters :)...
<input type="text" placeholder="★ emaN">

Closed 4 years ago.
I have an question about modify the tag type attribute problem. In my case, I want to dynamicly change the type to make it work or disabled.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style r = "1" type = "text/css">
h1 {
font-size: 20px;
}
</style>
<style r = "2" type = "not work">
h1 {
font-size: 40px;
}
</style>
</head>
<body>
<script>
var style1 = document.querySelector('[r="1"]')
var style2 = document.querySelector('[r="2"]')
</script>
<h1>this text can be either 20px or 40px</h1>
<input type="button" value="make text 20px" onclick = "style1.type='text/css';style2.type='not work'">
<input type="button" value="make text 40px" onclick = "style2.type='text/css';style1.type='not work'">
</body>
</html>
So here's the example : click me
It works on chrome, but nor work in ie11, safari. Anybody can help ? Thanks a lot.
Addition: What i am doing is to change page style depends on some condition, say: language. In some reason I cant use mvvm framework.
That's not how you do it, actually. It's bad practice to change styles this way. It's better to change just one element style and not whole page style
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type = "text/css">
h1 {
font-size: 20px;
}
</style>
</head>
<body>
<script>
function changeStyle(fontSize) {
var heading = document.querySelector('h1')
heading.style.fontSize = fontSize;
}
</script>
<h1>this text can be either 20px or 40px</h1>
<input type="button" value="make text 20px" onclick = "changeStyle('20px')">
<input type="button" value="make text 40px" onclick = "changeStyle('40px')">
</body>
</html>
I am creating a web app in which i want to use a date picker
<script src="js/bootstrap-datetimepicker.min.js"></script>
<script src="js/bootstrap-datepicker.js"></script>
<link rel="stylesheet" href="documents/css/reset.css"/>
<link rel="stylesheet" href="css/BeatPicker.min.css"/>
<link rel="stylesheet" href="documents/css/demos.css"/>
<link rel="stylesheet" href="documents/css/prism.css"/>
<script src="js/jquery-1.11.0.min.js"></script>
<script src="js/BeatPicker.min.js"></script>
these are the script and link i downloaded from the web
this is my input field where i want to use datepicker
<body>
<input type="text" data-beatpicker="true"/>
</body>
but there is a by default button with the textbox
i used the css to remove the button by making the visibility:hidden;
<style>
button, input[type="button"] {
background-color: #D36161;
border: medium none;
color: #FFFFFF;
cursor: pointer;
font: bold 14px arial,serif;
margin: 3px;
padding: 4px;
visibility: hidden;
width: 72px;
}
</style>
but when i try to add another button it also disabled because of the stylesheet where i put visibility:hidden
this is my button with id
<button id="butt">close</button>
i edited th stylesheet like this
<style>
.butt{
visibility:visible;
}
</style>
but still it is not showing me the desired button
how can i do? i want to disable the button with textbox but visible other button
You are using a library called "BeatPicker".
Before messing arrond with the css, you should read the documentation.
To remove the 'clear' button you will need to add the following attribute to the date input
data-beatpicker-module="clear"
This will remove the clear button
More features are available here: http://act1gmr.github.io/BeatPicker/demos.html
A class selector is preceded by ., and an ID selector is preceded by #. So in your code, change the selector to #butt, because it is the ID of your button.
Try something like this:
<!DOCTYPE html>
<html>
<head>
<style>
button.visible {
visibility: visible
}
button.hidden {
visibility: hidden
}
</style>
</head>
<body>
<button class="visible">This is a visible button</button>
<button class="hidden">This is an invisible button</button>
<button>Notice that the invisible button still takes up space.</button >
</body>
</html>
Do the following
change button, input[type="button"] to .beatpicker-clearButton so you don't have this problem any more or as Adi Darachi sad add clear to the data-beatpicker-module attribute to remove the button
Use this
<body>
<input type="text" data-beatpicker="true" data-beatpicker-position="['*','*']" data-beatpicker-module="today,clear" />
</body>
Add the following css. This will hide only the beatpicker clear buttons.
.beatpicker-clearButton {
display: none;
}
I got a problem with tag. I have list of clickable phone numbers on the page and I want to mark used urls.
I created small example and tried to use :visited selector to change color for clicked urls, but it doesn't work.
Let me show the code:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.phone:visited {
color: red;
}
.phone {
color: blue;
}
</style>
</head>
<body>
<h1>Hi</h1>
<a class="phone" href="tel:#">Call me</a>
</body>
</html>
I found in Google Chrome inspector, that css works correctly (I manually added "visited" class and url's color was changed), but browser doesn't mark url as visited after click.
Is there any chance to fix this behavior?
Thank you!
Nothing will happen on desktop, because desktop browsers don't know what to do with tel:.
You could use something like jQuery to achieve this on desktop.
$('.phone').click(function() {
$('.phone').css({"color": 'red'});
});
You have to assign class through jquery.
$('.phone').click(function () {
$(this).addClass("visited");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.visited {
color: red !important;
background-color: yellow;
}
.phone {
color: blue;
}
</style>
</head>
<body>
<h1>Hi</h1>
<a class="phone" href="#">Call me</a>
<a class="phone" href="#">Calling you</a>
</body>
</html>
So manage with javascript session and additional css class will be handle your problem
<style type="text/css">
.selected {
color: red !important;
}
.phone {
color: blue;
}
</style>
JS
<script type="text/javascript">
var a = document.getElementsByTagName("a");
//I assumed there is only one a link so tried with index 0
if(sessionStorage.getItem("visited") != null) a[0].classList.add("selected"); //check visited link then add class selected
a[0].addEventListener("click",function(){
sessionStorage.setItem("visited","true");//set session visited
this.classList.add("selected");
});
</script>
You need to declare .phone first before .phone:visited in your css.
I'm trying to show a popup when the mouse is over "a" element.
The problem is that I want to keep the popup when the mouse is over the popup element but the popup disappear when the mouse is over it.
The popup is just under the <a> element (on the display).
This is my code
HTML:
<ul>
<li>
<a id="test">
<div>
Some text
</div>
<div id="popup">
<ul>
<li><a>text0</a>
</li>
<li><a>text1</a>
</li>
</ul>
</div>
</a>
</li>
<li> TEXT
</li>
</ul>
CSS:
#popup {
display:none;
}
#test:hover #popup {
display:block;
}
I tagged the question 'JAVASCRIPT / JQUERY' because if there is a solution with them, it would be welcome.
EDIT
THIS IS ACTUALLY MY CODE, and it doesn't works
Before your start coding take a look at jQueryUI Tooltip (http://jqueryui.com/tooltip/ ).
It does what you want with minimal programming requirements.
From the doku:
Customizable, themeable tooltips, replacing native tooltips.
Example:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>jQuery UI Tooltip - Default functionality</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
<script>
$(function() {
$( document ).tooltip();
});
</script>
<style>
label {
display: inline-block;
width: 5em;
}
</style>
</head>
<body>
<p>Tooltips can be attached to any element. When you hover
the element with your mouse, the title attribute is displayed in a little box next to the element, just like a native tooltip.</p>
<p>But as it's not a native tooltip, it can be styled. Any themes built with
ThemeRoller
will also style tooltips accordingly.</p>
<p>Tooltips are also useful for form elements, to show some additional information in the context of each field.</p>
<p><label for="age">Your age:</label><input id="age" title="We ask for your age only for statistical purposes." /></p>
<p>Hover the field to see the tooltip.</p>
</body>
</html>
#popup {
display:none;
}
a:hover + #popup {
display:block;
}
Try this should work.
jsfiddle
If you really wanna make a nice popup use this:
http://getbootstrap.com/2.3.2/javascript.html#popovers
If you're not looking to use jQuery, you can make the div a child of the a tag and use some css trickery to make it all work (http://jsfiddle.net/TMBGm/):
<a>some text<div>popup text</div></a>
a {
position: relative;
}
a div {
display: none;
}
a:hover div {
display: block;
position: absolute;
}
The adjacent sibling selector is perfect for this example:
div {
display: none;
}
a:hover + div {
display: block;
}
Demo: http://jsfiddle.net/G4hd9/
Article: http://css-tricks.com/child-and-sibling-selectors/
This will keep the popup active while the user is hovering it if the element is not related, otherwise if its a child of the element it won't lose focus.
#popup:hover {
display:block
}
I am sure there is a proper term for it but don't know it. How can I make a small note pop up when a user is on each field? Like let's say they go to name field; then as soon as they click on the name field on the right side, I want a small note to show up giving them a message like "make sure you use full name". I want to do this for a couple of fields I have. How can I do this?
Are you looking for ToolTips? Checkout these collection from smashing magazine.
I use this plugin for what you are asking. JQuery tooltip
FlowPlayer.org has a good jQuery tooltip plugin that you can use.
Check this for a demo of using it on a form(it suits your requirement)
