please help me.
I used to do some programming ages ago in PHP3 and now I am slowly getting on track again, using new features like jquery.
I made class for dealing with errors on the site, which works pretty fine, but now I have problem with simple peace of code which should deal with error itself. I made simple class function : (..part of the switch () )
default :
echo('<script type="javascript">
$("#infoLine").show ("clip", 300, "vertical");
$("#infoLine" ).text("'.$this->strErrorInfo.'");
$("#infoLine").addClass(".error");
</script>');
This part doesn't works Script part appears in html code, div with id infoLine is defined in the code like this:
<footer>
<div id="infoLine"></div>
</footer>
error generating code is:
<section id="main"><div style="float:none; position: relative;">
<?php
$error->intErrorOnLine = 15795;
$error->strErrorInfo = "This is really big error! Everything works fine";
$error->strErrorInFile = "some.html";
$error->showErrorLine();
css added to the code is like:
#infoLine {
display: none;
position: relative;
bottom: 2em;
width: 95%;
margin-right: auto;
margin-left: auto;
max-height: 50px;
}
.error {
position: relative;
bottom: 2em;
width: 95%;
margin-right: auto;
margin-left: auto;
max-height: 50px;
border-radius: 5px;
border-style: solid;
border-color: #bb0000;
border-width: 2px;
background: rgba(255, 150, 150, 0.8);
}
div msg will never appear and I don't know why. I know I do something really stupid, so please don't beat me :) - thank you very much for any help

I ask my question as someone who knows pretty much nothing (nothing at all) about coding. I am clearly very confused about how HTML, CSS, and JS interact.
I am creating a Squarespace website, and I found an FAQ form from Codepen.io that I would like to include on a specific page of the website. I want to know how to approach inserting the HTML, CSS, and JS into a Squarespace code block.
I am able to copy and paste the HTML part of the code into the Squarespace code block feature and the FAQ form shows up, but without all the colors/fonts/styles that the CSS and JS code apparently bring to it. That is about all I got to "work." Below I provided a link to the code I am referring to. I hope this is all making sense.
FAQ form in question: codepen.io/sarenz/pen/azGLRg
*I have added the CSS and JS codes for context

Congrats on getting started in the coding world! Squarespace has a tutorial on adding custom HTML, CSS, and JS to your website: link
As far as understanding how HTML, CSS, and JS interact, there are plenty of tools available to help you learn depending on your preferred learning style: Google Results
Here's the basic run-down:
HTML: The content that you want on your website
CSS: The formatting of that content
JS: Logic to change the content and formatting based on conditions or events (ie user clicks a button)
First for all: No, I'm not looking for the property position: absolute;
What I want to is to create a field that displays some text. I want to display that field exactly in the middle of the page and then fade out the background, doesnt matter, where the div is placed in the code.
At the moment it looks like that:
https://www.dropbox.com/s/wiljdh1xjj3we1c/Capture1.PNG
https://www.dropbox.com/s/chw7pdes5fdcj3u/Capture2.PNG
How can I place an Elemtn ABSOLUTE in the middle of the page, doesnt matter where it is written in the code?
Now I could just say well, I will place it on top of the content. But the problem is, in this field is displayed some information that generates in the content, so I have to put it in the code after the content.
I hope, someone can help me :)
PS: If you have another solution to solve something like this... feel welcome to tell me! I just want something like an alert();-Box with my own style.
EDIT: Some effort: (basically already shown with the screenshots, but here some code; just didnt want to make it confusing)
I save the text as following:
// Save Help-Text
ob_start();
?>
This is the main page. There is no help available!
<?php
$help = ob_get_clean();
I display the text as following: (echo create_help($help); creates the help-tag and displays it)
function create_help($content){
$help = "
<div id=\"help-bg\" class=\"closehelp\" ></div>
<div id=\"help\" >
<img src=\"../images/close.png\" class=\"closehelp\" />
$content
</div>
";
return $help;
}
This is the CSS for the box:
/* Help-box style */
#help
display: none;
position: absolute;
margin-left: auto;
margin-right: auto;
background-color: #B8DBFF;
border: 5px solid rgb(58, 100, 250);
border-top: 30px solid rgb(58, 100, 250);
border-radius: 5px;
padding: 20px;
width: 600px;
z-index: 1001;
#help img
position: absolute;
margin-left: 595px;
margin-top: -47px;
height: 25px;
width: 25px;
/* Makes background of Help-box transparent black */
#help-bg
background-color: black;
z-index: 1000;
width: 100%;
height: 100%;
position: fixed;
left: 0px;
top: 0px;
opacity:0.6;
display: none;
First of all I would recommend using position:fixed; instead of position:absolute; because the alert would scroll within the page. If you have a fixed height and width try something like
margin: -150px 0 0 -150px;
left: 50%;
top: 50%;. This CSS-Code will center your div horizontally and vertically (Demo -> http://demo.tutorialzine.com/2010/03/centering-div-vertically-and-horizontally/demo.html). But if you are using an dynamic height maybe you should consider using jQuery or give it a fixed top position.
try this:
html, body{
position: relative;
}
.yourAbsoluteClass{
position: absolute;
width: 50%;
top: 25%;
left: 50%;
}
I am trying to learn Javascript and struggling! I have got my head around CSS & HTML to an ok level and have made a very basic file to help me learn basic Javascript functions. I just want to know if what I am doing is on the right path? I want to click on the different color boxes and change the main box.
I have made a fiddle link here: http://jsfiddle.net/Margate/mN9hs/
This should be self explanatory. Nothing that will ever be used I just want to learn with it!
After hours trying to work it out I am completely stuck as to why it is not working!
Thank you very much for any help / guidance....
<!DOCTYPE html><html><head><title> Learning Page!</title>
<style type="text/css">
#MainContent{position: relative; margin: 0px auto; top: 10px; border: 2px solid black; width: 500px; height: 250px;}

</style>
</head>
<body>
<div id="MainContent">
<div id="ChangeThis"></div>
<div id="ColourBoxContiner">
<div id = "RedBox" onclick="ChangeColorOne()"></div>
<div id = "YellowBox" onclick="ChangeColorTwo()"></div>
<div id = "GreenBox" onclick="ChangeColorThree()"></div>
</div>
</div>
<script>
function ChangeColorOne() {
document.getElementById('ChangeThis').style="background.color:orange";
}
function ChangeColorTwo() {
document.getElementById('ChangeThis').style="background.color:black";
}
function ChangeColorThree() {
document.getElementById('ChangeThis').style="background.color:blue";
}
</script>
</body>
</html>
When you are setting the background color you should be using "backgroundColor" without the period, like this:
function ChangeColorOne()
{document.getElementById('ChangeThis').style.backgroundColor="orange";}
function ChangeColorTwo()
{document.getElementById('ChangeThis').style.backgroundColor="black";}
function ChangeColorThree()
{document.getElementById('ChangeThis').style.backgroundColor="blue";}
BTW, Codecademy is a great place to go to learn Javascript. You can also use w3Schools as a reference.
The fiddle won't work (or won't for me on chrome) while you have the JavaScript set as onLoad, try No wrap - in <head> and you've a little syntax error in your JavaScript. Apart from that you were very close.
eg.
function ChangeColorOne() {
document.getElementById("ChangeThis").style.backgroundColor = "orange";
}
See this updated version on your fiddle: http://jsfiddle.net/mN9hs/1/
document.getElementById('ChangeThis').style="background.color:orange";
->
document.getElementById('ChangeThis').style.backgroundColor = "orange";
Stop using HTML onclick attributes and bind the click events through JS. The structure is yourElement.addEventListener("click", yourfunction); if your function is available in the scope. If you assign more than one, and you do not prevent your event from bubbling, all your observers will get the message.
Okay buddy here is your snippet in working condition.
Actually you need to do as:
function ChangeColorOne()
{document.getElementById('ChangeThis').style.backgroundColor="orange";}
function ChangeColorTwo()
{document.getElementById('ChangeThis').style.backgroundColor="black";}
function ChangeColorThree()
{document.getElementById('ChangeThis').style.backgroundColor="blue";}
ChangeColorOne();
ChangeColorTwo();
ChangeColorThree(); // call them all
Have a look. Hope it will help you =) .
I am very new to Javascript. I have been looking into using Javascript to edit css style properties. I have searched the web and looked at a lot of different problems. Even with all of that, it is probably my inexperience as to why I can't figure out what is wrong with my code. What adds to the problem is that there are so many ways to do this. Anyway here are the specifics.
What I want it to do:
When someone clicks on the link in the code, I want the hidden DIV (which will just be near the top of my waiting to be called on) to have its visibility switched to visible so as to create a new layer on the page.
My code:
<html>
<head>
<script language="javascript">
function newwindow() {
var showme = document.getelementbyid("testing");
showme.style.visibility = "visible";
}
</script>
</head>
<body>
Show me my hidden layer
<div id="testing" style="position: absolute; visibility: hidden; left: 50%; top: 50%;
border: 1px solid darkblue; width: 400px; height: 300px; line-height: 300px;
text-align: center; vertical-align: middle;
margin-top: -150px; margin-left: -200px; background: lightgray">HELLO!!!</div>
</body>
</html>
Now, I know there are a lot of ways to do this. But can someone show me what to tweak in the code I gave to make the way I am writing this work? Thanks so much for your time.
It is document.getElementById not document.getelementbyid
Working Demo
use this code
<html>
<head>
<script language="javascript">
function newwindow() {
var showme = document.getElementById("testing");
showme.style.visibility = "visible";
}
</script>
</head>
<body>
Show me my hidden layer
<div id="testing" style="position: absolute; visibility: hidden; left: 50%; top: 50%;
border: 1px solid darkblue; width: 400px; height: 300px; line-height: 300px;
text-align: center; vertical-align: middle;
margin-top: -150px; margin-left: -200px; background: lightgray">HELLO!!!</div>
</body>
</html>
I try to achieve something like the Facebook does when you type #<NAME_OF_A_FRIEND> in a reply. After you choose a friend, the name of that friend is highlighted with a blueish background, so you know it's a separate entity in that text.
I've "inspect element"-ed that textarea and there is no div placed on top of the textarea.
Can anyone give me a clue about how that is done ?
I have a completely different approach to this issue using HTML5. I use a div with contentEditable="true" instead of a textarea (wich I was using until I got stuck with the same problem you had).
Then if I want to change the background color of a specified part I just wrapp that text with a span.
I am not 100% sure if it is the correct approach as I am a newbie in HTML5 but it works fine in all the browsers I have tested it (Firefox 15.0.1 , Chrome 22.0.1229.79 and IE8).
Hope it helps
See this example here. I used only CSS and HTML... The JS is very more complex for now. I don't know exactly what you expect.
HTML:
<div id="textback">
<div id="backmodel"></div>
</div>
<textarea id="textarea">Hey Nicolae, it is just a test!</textarea>
CSS:
#textarea {
background: transparent;
border: 1px #ddd solid;
position: absolute;
top: 5px;
left: 5px;
width: 400px;
height: 120px;
font: 9pt Consolas;
}
#backmodel {
position: absolute;
top: 7px;
left: 32px;
background-color: #D8DFEA;
width: 53px;
height: 9pt;
}
The textarea has background-color: transparent; the extra div you're looking for is behind it, with the same text and font as the textarea, but different colours.
A short example to illustrate the point:
<!DOCTYPE html>
<html>
<head>
<title>Demo</title>
<style>
* { font-family: sans-serif; font-size: 10pt; font-weight: normal; }
.wrapper { position: relative; width: 400px; height: 400px; outline: solid 1px #666; }
.wrapper > * { position: absolute; top: 0; left: 0; height: 100%; width: 100%; margin: 0; padding: 0; }
.highlighter { background-color: #fff; color: #fff; }
.highlight { background-color: #9ff; color: #9ff; }
textarea { background-color: transparent; border: 0; }
</style>
</head>
<body>
<div class="wrapper">
<div class="highlighter">
This <span class="highlight">is a</span> demonstration.
</div>
<textarea>
This is a demonstration.
</textarea>
</div>
</body>
</html>
Of course, this does not update the special div as you type into the textarea, you need a lot of JavaScript for that.
hi you can check this jquery autosuggest plugin similar to facebook .I have used this to achive the same functionality you required
http://www.devthought.com/2008/01/12/textboxlist-meets-autocompletion/
I would suggest changing the text you want to assign a background inline to to display: inline-block; background-color: #YOURCOLOR;. This should do exactly what you want it to do without all the complexities of some of the above answers.
Ultimately your CSS should look something like this:
.name {display: inline-block; background-color: purple;}
Then add some sort of event listener in jQuery (not sure how you're identifying that it is a name) and inside that conditional put:
$(yourNameSelectorGoesHere).addClass(".name");
