So, I am trying to do a little browser game with Javascript (jQuery). I have already fighting system and now I am trying to do movement system, so you can move around the world.
Let's say that I want to open map and go to town and then to shop. What is the best way to open MAP window and close all other windows, then open TOWN window and close MAP window, then open SHOP window and close TOWN window?
I tried something, but it feels a little bad.. Is this a good way to do it or not?

The code you have written looks functional. I don't see any problems. The only issue you will encounter is when you start introducing more details and complexity.
Just make sure you start making these into functions with annotations otherwise you will get lost.
An aside, consider the Unity Development Platform or Flash or consider using libraries which will save you a great deal of time: for example. Crafty
Otherwise, you'll learn as you'll continue coding. Focus on functionality and then optimization. Doing both with limited experience can be counterproductive.
Cheeers
you can select multiple elements at the same time like this
$("#mapBtn").click(function(){
$("#map, #exit").show();
$("#shop, #mapBtn").hide();
});
that will at least save you some space.

I am working on a project and the client gave me a task to open a browser window on the click of button like a popup but it is not a popup, I have to open a browser window and that is not complicated but they gave me a design to give border radius to browser window and make browser window's sides CURVY like in the image.
I did not find any solution of this. Is it possible? If yes then please reply me.
Thanks in advance
ANSWER: You cannot make a WINDOW with curved corners
You would have to rewrite the browser code to do so.
CSS does not apply to the browser itself, only the content
But you can pop a curved div:
window.addEventListener("load", function() { // on page load
document.getElementById("popBtn").addEventListener("click", function() {
document.getElementById("popDiv").classList.toggle("hide");
});
});
body {
background-color: #CEEDDC
}
div.pop {
width: 300px;
height: 300px;
padding: 10px;
border: 2px solid #000;
border-radius: 55px;
-moz-border-radius: 15px;
background-color: red;
position: absolute;
top: 100px;
left: 200px;
}
.hide {
display: none;
}
<button id="popBtn" type="button">Pop</button>
<div id="popDiv" class="pop hide">
<h1>Here you could have an iFrame if needed</h1>
</div>
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>

</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");
I like how Facebook keeps that toolbar on the bottom of the page.
Does that require cross-browser ninja skills?
Their JavaScript/CSS files are huge so I am having a hard time narrowing down the implementation (for learning purposes).
You can achieve the effect with CSS.
Here's a basic example. No, it doesn't require cross-browser ninja skillz. =)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Facebook Bar</title>
<style type="text/css">
body {
margin: 0px;
padding: 0px;
overflow: hidden;
}
#page {
margin: 10px;
overflow: auto;
height: 93%;
}
#bottom {
width: 100%;
background: #18f8f8;
text-align: center;
}
</style>
</head>
<body>
<div id="page">
Other stuff on page
</div>
<div id="bottom">Bottom stuff goes here</div>
</body>
</html>
The best is to install Firebug and see how they did it. When I see interesting things on the web, Firebug is the best way to analyze it's HTML structure, attached CSS and you can even directly modify the CSS/HTML structure to see how it changes. Everything you see on a website can be simply read. Remember, the source (HTML, CSS, JavaScript) gets delivered with it :)
That solution doesn't work well for pages that have content extending beyond the bottom of the browser window.
Try something like this instead:
<div style="display: block;
position: fixed;
text-align: center;
z-index:1000;
bottom: 0;
left: 0;
width: 100%;
color: #999999;
clear: both;
height: 15px;
border-top-style: solid;
border-top-width: 1px;
border-top-color: #b5b6b5;
background-repeat: repeat-x;
border-right-style: solid;
border-left-style: solid;
border-right-width: 1px;
border-left-width: 1px;
border-right-color: #b5b6b5;
border-left-color: #b5b6b5;
background-color: #e7e7e7;"></div>
