JavaScript - Javascript Styling

ok, I am using jQuery UI http://jqueryui.com

I have it all working but I wanted to style my form button

I am using this:

Code:

<button id="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">A button element</span></button>

that styles it, but doesn't work as I need it to be a form button?!

Please help?!

thanks

Hi guys,


I am after a script which will has parametres to modify the select menu in webpages.

I have looked at niceforms http://www.emblematiq.com/lab/niceforms/demo/

However i dont know how to apply it.

Any tips would be much appreciated.

Hi.

I want to make jQuery check, whether if I've supplied text into all fields. If not, then jQuery adds some styling to the input boxes pointing out, the user must type something.

However, I do not want to do many, many lines of jQuery to do this with all of the inputs. Is there a way to check which input is empty, and then add styling to the individual one? And then remove the style, if it's no longer empty. Like - ONE piece of code, that checks all of the inputs, and adds style to the ones, that are empty.

Here's what I have right now.

Code:

<script type="text/javascript">
$(function(){
	$('#register').click(function(){
		var username = $('#username').val();
		var password = $('#password').val();
		
		if(username == ""){
			$('#username').css({
				background: '#F3CACA',
				border: '1px solid #E61A1A'
			});
		}else{
			$('#username').removeAttr('style');
		}
		
		return false;
	});
});
</script>

I played around with if(username == "" || password == ""). It works, but then I got lost on how to add styles to the individual input that is empty.

I'm trying to call a javascript function from within my swf and I'm having a couple of problems which are confussing me somewhat.

I'm using this to call the function from flash:

Code:

ExternalInterface.call("pgcover");

I know that this is calling the function as I have set it trigger an alert action and this comes up properly.

But I don't want the function to trigger an alert, this is just for testing purposes.

I instead want it to change the styling on a div.

I have set up a test page where I have asigned the function to a button and this works, the div display changes from block to none.

When I get the swf to call the function setup to do the same thing, nothing happens.

Code:

function pgcover() 
{ 
  document.getElementById("unlayout").style.display= "none";
}

My swf is embedded in the html page that the javascript is on, I have checked all code and have rulled out spelling mistakes etc.

Any help with this would be amazing as it is driving me crazy.

Hey,

I have a page at http://www.webdev70.cocc-webdev.org/contact.html where I have styling on the radio and check boxes.

I'm working on another project for class now where I want onclick or onchange functions in the radio buttons. When the radio buttons have the class="styled" on them, the function will not execute. When that's removed, they do.

Here is the javascript for the styling:

Code:

var checkboxHeight = "25";
var radioHeight = "25";
var selectWidth = "190";


document.write('<style type="text/css">input.styled { display: none; } select.styled { position: relative; width: ' + selectWidth + 'px; opacity: 0; filter: alpha(opacity=0); z-index: 5; } .disabled { opacity: 0.5; filter: alpha(opacity=50); }</style>');

var Custom = {
	init: function() {
		var inputs = document.getElementsByTagName("input"), span = Array(), textnode, option, active;
		for(a = 0; a < inputs.length; a++) {
			if((inputs[a].type == "checkbox" || inputs[a].type == "radio") && inputs[a].className == "styled") {
				span[a] = document.createElement("span");
				span[a].className = inputs[a].type;

				if(inputs[a].checked == true) {
					if(inputs[a].type == "checkbox") {
						position = "0 -" + (checkboxHeight*2) + "px";
						span[a].style.backgroundPosition = position;
					} else {
						position = "0 -" + (radioHeight*2) + "px";
						span[a].style.backgroundPosition = position;
					}
				}
				inputs[a].parentNode.insertBefore(span[a], inputs[a]);
				inputs[a].onchange = Custom.clear;
				if(!inputs[a].getAttribute("disabled")) {
					span[a].onmousedown = Custom.pushed;
					span[a].onmouseup = Custom.check;
				} else {
					span[a].className = span[a].className += " disabled";
				}
			}
		}
		inputs = document.getElementsByTagName("select");
		for(a = 0; a < inputs.length; a++) {
			if(inputs[a].className == "styled") {
				option = inputs[a].getElementsByTagName("option");
				active = option[0].childNodes[0].nodeValue;
				textnode = document.createTextNode(active);
				for(b = 0; b < option.length; b++) {
					if(option[b].selected == true) {
						textnode = document.createTextNode(option[b].childNodes[0].nodeValue);
					}
				}
				span[a] = document.createElement("span");
				span[a].className = "select";
				span[a].id = "select" + inputs[a].name;
				span[a].appendChild(textnode);
				inputs[a].parentNode.insertBefore(span[a], inputs[a]);
				if(!inputs[a].getAttribute("disabled")) {
					inputs[a].onchange = Custom.choose;
				} else {
					inputs[a].previousSibling.className = inputs[a].previousSibling.className += " disabled";
				}
			}
		}
		document.onmouseup = Custom.clear;
	},
	pushed: function() {
		element = this.nextSibling;
		if(element.checked == true && element.type == "checkbox") {
			this.style.backgroundPosition = "0 -" + checkboxHeight*3 + "px";
		} else if(element.checked == true && element.type == "radio") {
			this.style.backgroundPosition = "0 -" + radioHeight*3 + "px";
		} else if(element.checked != true && element.type == "checkbox") {
			this.style.backgroundPosition = "0 -" + checkboxHeight + "px";
		} else {
			this.style.backgroundPosition = "0 -" + radioHeight + "px";
		}
	},
	check: function() {
		element = this.nextSibling;
		if(element.checked == true && element.type == "checkbox") {
			this.style.backgroundPosition = "0 0";
			element.checked = false;
		} else {
			if(element.type == "checkbox") {
				this.style.backgroundPosition = "0 -" + checkboxHeight*2 + "px";
			} else {
				this.style.backgroundPosition = "0 -" + radioHeight*2 + "px";
				group = this.nextSibling.name;
				inputs = document.getElementsByTagName("input");
				for(a = 0; a < inputs.length; a++) {
					if(inputs[a].name == group && inputs[a] != this.nextSibling) {
						inputs[a].previousSibling.style.backgroundPosition = "0 0";
					}
				}
			}
			element.checked = true;
		}
	},
	clear: function() {
		inputs = document.getElementsByTagName("input");
		for(var b = 0; b < inputs.length; b++) {
			if(inputs[b].type == "checkbox" && inputs[b].checked == true && inputs[b].className == "styled") {
				inputs[b].previousSibling.style.backgroundPosition = "0 -" + checkboxHeight*2 + "px";
			} else if(inputs[b].type == "checkbox" && inputs[b].className == "styled") {
				inputs[b].previousSibling.style.backgroundPosition = "0 0";
			} else if(inputs[b].type == "radio" && inputs[b].checked == true && inputs[b].className == "styled") {
				inputs[b].previousSibling.style.backgroundPosition = "0 -" + radioHeight*2 + "px";
			} else if(inputs[b].type == "radio" && inputs[b].className == "styled") {
				inputs[b].previousSibling.style.backgroundPosition = "0 0";
			}
		}
	},
	choose: function() {
		option = this.getElementsByTagName("option");
		for(d = 0; d < option.length; d++) {
			if(option[d].selected == true) {
				document.getElementById("select" + this.name).childNodes[0].nodeValue = option[d].childNodes[0].nodeValue;
			}
		}
	}
}
window.onload = Custom.init;

The code is way over my head so I'm not sure where the problem is, or if it could be fixed.

This is what one of my radio buttons looks like:
<input type="radio" name="puppy" value="1" class="styled" onchange="puppycheck()">Black and White Puppy


If the style tag is removed it works perfectly. There is CSS too, but I don't think the problem is in there.

Is there a script that automatically applies two different styles to the first two lines of text in a container, without using CSS?

Example:

======
This Would be Line One as a Title with its Own Style
This would be line two as a byline with a separate style

This is the main text of the paragraph... etc etc.
======


Thanks for any help.

I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. Could someone please explain what I am doing wrong?

here is my code so far...
Note: just for testing purposes I've put return false on everything so it displays a message when everythings ok.

Code:

....
<script type="text/javascript">
	window.onload = function() {
		document.forms[0].username.focus();
	}
	function validate(form)
	{
		var form = document.getElementById("reg");
		var e = document.getElementById("error");
		e.style.background = "red";
		
		for(var i = 0; i < form.elements.length; i++)
		{
			var el = form.elements[i];
			if(el.type == "text" || el.type == "password")
			{
				if(el.value == "")
				{
					e.innerHTML = "Please fill in all fields!";
					el.style.border = "1px solid red";
					el.focus();
					return false;
				} else {
					el.style.border = "1px solid green";
					return false;
				}
			}
		}
		var un = form.username;
		un.value = un.value.replace(/^\s+|\s+$/g,"");
		if((un.value.length < 3)|| (/[^a-z0-9\_]/gi.test(un.value)))
		{
			e.innerHTML = "Only letters,numbers and the underscore are allowed (no spaces) - 3-16 characters";
			un.focus();
			return false;
		}
		var pw = form.password;
		pw.value = pw.value.replace(/^\s+|\s+$/g,"");
		if((pw.value.length < 3) || (/[^a-z0-9]/gi.test(pw.value)))
		{
			e.innerHTML = "Only letters and numbers are allowed (no spaces) - 3-16 characters";
			pw.focus();
			return false;
		}
		e.innerHTML = "You filled in all the fields, well done!";
		e.style.background = "green";
		return false;
	}
</script>

I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free.

I have Googled, but there are so many that I am almost dizzy with the choices.

Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic.

Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once.

Does anyone know how to do this please?

Thanks so much for your help.

Does anyone know how to make URL links that use Javascript still work when
users have Javascript disabled on their browser?

The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version.

I tried the <script><noscript> tags, but I'm not sure if I'm using it
correctly, as my URL completely disappears.

Below is my HTML/Javascript code:

<p class="download">
<script type="text/javascript">document.write("<span
style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\"
onclick=\"window.open(
'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+
Math.floor( Math.random()*11 ) );\" >The Child Magazines Media
Kit</a></span> (PDF 1 MB) ");</script>
<noscript><span style="text-decoration: underline;"><a
href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf"
>The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript>
</p>

Hi Guys,
I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled!
I create the following code but it did not work

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>New Web Project</title>
<script language="JavaScript" type="">
function changeColor(){
document.bgColor = "Gray";
}
</script>
</head>
<body>
<script language="JavaScript" type="text/javascript">
var person = "";
person = prompt('What is Your Name:');
if (person == "Foo") {
document.write("<h1 />Welcome " + person);
document.bgColor = "Yellow";
}
else {
document.write("<h1 />Access Denied!!!!");
document.bgColor = "Red";
document.getElementById("gree").disabled = true;
}
</script>

<div>
<p/><input id="gree" type="button" value="Gray " onClick="changeColor();">
</div>
</body>
</html>

as you can see I used the:
document.getElementById("gree").disabled = true;
but it did not work , could you please give an idea how I can solve this problem?
Thanks

Hi,

I have the following code snippet:
test.html
======
<script language="javascript" type="text/javascript">
var testVariable = "test";
</script>
<script language="javascript" type="text/javascript" src="test.js">
</script>

test.js
=====
var testVariable = window.top.testVariable;

In firefox, I'm able to access testvariable defined within test.html in test.js.

But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html.

Can any one please let me know how i can make it work in chrome?. Am i missing something here?.

I got an index.php
Code:

<html>

<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>

As you can see, each of the option brings specific value "../komik1/|23"
komik1 is a directory
| is a delimiter
23 is the pages in one chapter and can be considered also as how many images are there on a specific directory

This is my bacakomik.php
Code:

<?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do  {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">

With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this?
I believe that the fix should be somewhere on input tag inside OnClick, or do you know where?

Anyway, I found this on the net
http://p2p.wrox.com/php-faqs/11606-q...avascript.html
Please help me to those who can...

Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function.

This is the code I want to activate:

Code:

<script type="text/javascript"><!--
$('#button-cart').bind('click', function() {
	$.ajax({
		url: 'index.php?route=checkout/cart/update',
		type: 'post',
		data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
		dataType: 'json',
		success: function(json) {
			$('.success, .warning, .attention, information, .error').remove();
			
			if (json['error']) {
				if (json['error']['warning']) {
					$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
				
					$('.warning').fadeIn('slow');
				}
				
				for (i in json['error']) {
					$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
				}
			}	 
						
			if (json['success']) {
				$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
					
				$('.success').fadeIn('slow');
					
				$('#cart_total').html(json['total']);
				
				$('html, body').animate({ scrollTop: 0 }, 'slow'); 
			}	
		}
	});
});
//--></script>

And this is how I want the format of the function to be:

function testsession() {
if there is a session called 'hiredate' {
activate the script above
}
else {
var el = document.getElementById("product_data");
}
}
