JavaScript - Color Coding For Programming Syntax
I am trying to display code on a web page in a readable and formatted fashion with color highlighting idealy.
I am assuming that something of this nature would have to be done with javascript to calculate the css styling based on the keywords. Been trying to find something on this for a while but cant find anything Any suggestions would be appreciated Similar TutorialsI'm working on a new custom theme for my WordPress based site, and up until now I've been using the following PHP code to color code links based on whether the post was in the "Wii" category, "Xbox" category, or "PlayStation" category: PHP Code: <li> <?php if (in_category(3) ) { ?> <a style="color:#990000;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a> <? }elseif (in_category(4) ) { ?> <a style="color:#669900;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a> <? }elseif (in_category(7) ) { ?> <a style="color:#0099cc;" href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a> <? } else { ?> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a> <? } ?> </li> Thing is, I've now installed a plugin called "Recently Popular" that logs all visits and can output which posts were viewed the most in the past X days/weeks/months/etc. and the author has it set up to only allow HTML formatting via this line: PHP Code: <?php get_recently_popular(1, 'WEEK', 5, 0, 0, '<a href="%post_url%" rel="bookmark" title="%post_title%">%post_title%</a>'); ?> I've tried sticking PHP in the line, but it only takes HTML. I've tried sticking one of these lines in each of the conditional statements above, but realized that this line outputs the entire "Recently Popular" list, not just one item - so everything would end up being the same color still. I contacted the plugin author, who said that without hardcoding there's no way to get around this via the plugin, but that outputting it normally and running it through JavaScript might give me a way to apply CSS styling to it after it's been rendered. I'm not experienced with JavaScript, unfortunately... does anyone know how I can do this? My site will change color schemes when a user presses the button in the top left. I want to add a third theme though. I can't figure it out though. My html as relevent Code: <!--EXTERNAL FILES--> <link rel="stylesheet" type="text/css" href="main.css" /> <!--[if IE]><link rel="stylesheet" type="text/css" href="mainIE.css" /><![endif]--> <link id="altstyle" rel="stylesheet" type="text/css" href="main.css" /> <script type="text/javascript" src="main.js"></script> <!--STOP EXTERNAL FILES--> <title>Votillity.com</title> <!--CSS INTERNAL--> <!--CSS INTERNAL--> <!--JAVASCRIPT INTERNAL--> <!--JAVASCRIPT INTERNAL--> </head> <body onload="startTime()"> <img class="Zindexsty1" style="position: fixed; top: 0px; left: 0px;" src="http://votillity.com/VotillityLogo1.png" alt="VOTILLITY" /> <img class="Zindexsty2" style="position: fixed; top: 0px; left: 0px;" src="http://votillity.com/VotillityLogo2.png" alt="VOTILLITY" /> <button id="altstyact" class="button" style="position: fixed; top: 0px; left: 170px; width: 60px;">Theme</button> Javascript Code: //ALTERNATE STYLES
function changeStyle()
{
var obj1=document.getElementById('altstyact');
var obj2=document.getElementById('altstyle')
test=true;
obj1.onclick=function()
{
test==true?
(obj2.href='main2.css',obj1.firstChild.nodeValue='Classic',test=false):
(obj2.href='main.css',obj1.firstChild.nodeValue='Ice',test=true)
}
}
if(window.addEventListener)
{
window.addEventListener('load',changeStyle,false);
}
else
{
if(window.attachEvent)
{
window.attachEvent('onload',changeStyle);
}
}
//STOP ALTERNATE STYLES
I don't think you need the css's. If, however, I'm wrong just let me know. Keep in mind that the javascript is external. Here's my site if you need a better look Votillity Thank you Hi, I'm faced with a problem trying to set background color under IE7. I have the following Javascript: Code: function showLayer793BKColor(id)
{
var txtObj = document.all(id);
if (txtObj.style.display == 'none')
{
txtObj.style.display = ''
txtObj.style.backgroundColor = 'grey';
}
}
function hideLayer793BKColor(id)
{
var txtObj = document.all(id);
if ( txtObj.style.backgroundColor == 'grey' )
txtObj.style.display = 'none';
}
These functions are used to show or hide div blocks. These blocks are, for example, specified in the following way: Code: <div id="l_gct5tekst" style="display:none"> <b>GCT 5. Eerste verkenning problematiek</b> and, for example, Code: <div id="l_Keuze" style="display:none"> <br/> <b>GCT 5</b> <br/> </div> The whole configuration works smoothly when using IE8. However, when using IE7 I get an error msg like "Invalid value for property". When I use the Color propert iso the BackgroundColor property I get no error anymore but of course I don't have a background color anymore then. In what way can I specify the use of a background color under IE7 ? Or is just not possible in one way or the other. Furthermore, what more differences between JS under IE7 and IE8 do I have to take into account ? Do I also have to rewrite my div block in some way (using some attribs ?) to cope with IE7 ? Thanks in advance, Diederick van Elst Hi! New to JS... have been trying to rework this to call additional, independent sets of colors to cycle through (so it would loop thru a set of grays, a set of primary colors, etc). I would use perhaps a different function name in the HTML to call different sets of colors. If this is more complex than I think it is, I think 3 sets would be plenty. Would be hugely grateful for any help, thanks so much in advance. (demo link of script in current state at bottom) Code: <html><head><title></title>
<script language=javascript>
colors = ["#cacdca", "#b2b4b2", "#969896", "#7d7f7d", "#ffff00"];
cRGB = [];
function toRGB(color){
var rgb = "rgb(" + parseInt(color.substring(1,3), 16) + ", " + parseInt(color.substring(3,5), 16) + ", " + parseInt(color.substring(5,7), 16) + ")";
return rgb;
}
for(var i=0; i<colors.length; i++){
cRGB[i] = toRGB(colors[i]);
}
function changeColor(target){
var swapper = navigator.appVersion.indexOf("MSIE")!=-1 ? toRGB(document.getElementById(target).style.backgroundColor) : document.getElementById(target).style.backgroundColor;
var set = false;
var xx;
for(var i=0; i<cRGB.length; i++){
if(swapper == cRGB[i]){
if(((i+1)) >= cRGB.length){
xx = 0;
}else{
xx = i+1;
}
document.getElementById(target).style.backgroundColor = colors[xx];
document.getElementById(target).style.backgroundImage.show;
set = true;
i=cRGB.length;
}
}
set ? null : document.getElementById(target).style.backgroundColor = colors[1];
}

Demo: http://theclutch.com/rollover_color_..._bgndimage.htm Hi I recently started researching about programming and was interested right away. I'm new to all this and need a place to start. Any help would be greatly appreciated and look forward to posting on this forum. IndyNS I am trying to create a dynamic form on my webpage. What I want to do is repeat this process multiple times on the same page. I know I have to have unique id's but I am not for sure how to set them. // JavaScript Document function addRowToTable(){ var tbl = document.getElementById('Division'); var lastRow = tbl.rows.length; // if there's no header row in the table, then iteration = lastRow + 1 var iteration = lastRow; // var iteration = lastRow + 1; var row = tbl.insertRow(lastRow); // cell 0 var cell0 = row.insertCell(0); var el = document.createElement('input'); el.type = 'text'; el.NAME = 'Resource[]'; el.size = 30; cell0.appendChild(el); //cell 1 var cell1 = row.insertCell(1); var el = document.createElement("select"); cell1.innerHTML + '<option value="0">Avaliable</option>' + '<option value="1">Busy</option>' //cell 2 var cell2 = row.insertCell(2); var el = document.createElement('input'); el.type = 'text'; el.NAME = 'Comment[]'; el.size = 25; cell2.appendChild(el); } Im having a problem with my Android applet I am creating using a program called Eclipse It reads the error: 'The method onCreateOptionsMenu(Menu) in the type Activity is not applicable for the arguments (Menu)'. Here is what I have written: [code] public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater awesome = getMenuInflater(); awesome.inflate(R.menu.main_menu, menu); return true; } [code] Problem: When I click the compute button, it does not do anything. It does not go to function CALCULATE and do its stuff . Please help me. This is my PHP code. Code: echo "<table border=1>";
while($row_contestant<$numrows_criteria)
{
$CId=mysql_result($result_contestants,$row_contestant,"CId");
$CName=mysql_result($result_contestants,$row_contestant,"CName");
echo "<tr><td width = '10'>$CId</td><td>$CName</td>";
for($start2 = 1;$start2 <= $counter;$start2++)
{
echo "<td><input type = 'text' name = 'cr[]' value = ''></td>";
}
$row_contestant++;
echo "<td><input type = 'text' name = 'rating' value = ''></td><td><input type = 'Button' name = 'getAvg' value = 'compute' onClick = calculate()></td></tr>";
}
echo "</table>
<p>";
}
This is my Javascript calculate function code Code: function calculate() {
sum = 0;
for(i = 0;i<=Number(document.frmOne.counter.value);i++)
{
sum = sum + Number(document.frmOne.cr[i].value)
}
document.frmOne.rating.value = sum
}
The output: Any help would be highly appreciated. God Bless. hi every one i;m new here and i love to know programming languages and some friends adviced me to start with java script then php , and i guess i'm at the right place can you please tell how to start and where to begain i'm really don't know anything about programming
I'm currently using an automation software to automate a series of steps I perform on my computer. One of the tasks involves hundreds of If/Then loops, extracts text from websites using an embedded web browser, computes equations and write text files. The thing is, in order to share this with somebody else, they also need the same automation software installed, and then need to import it. So it's a process I'm trying to replace by creating a small program with a GUI that involves a simple installation on the user's PC (or ideally without installation). The language must be flexible enough to perform the same actions that I listed above - and more preferably. I'm a complete novice with anything besides HTML/CSS so I'm looking for A flexible programming language that isn't rocket science to learn from scratch and is ideal for small stand-alone programs The ability to create a GUI. I'd be happy to read any good reference you have about the language/design knowledge needed for GUI's. Thanks in advance I have searched all over for tutorials on multiplayer game programming. I cannot seem to find anything relevant to my question, though. I don't even think that I can use javascript, but as I said, I do not know where to start. All I want, for now, is to make something simple like tic-tac-toe or rock-paper-scissors, which will be played by two users on two machines. Then once I've gotten that, I can move onto making something more in depth. Any push in the right direction is greatly appreciated! -Shane hi again, I want to say thank you for all of the help and I have the last assignment that she wants us to do and I had to pull up another assignment that she wanted us to build upon( which is one of those coding without anything advance) Code: <html>

Directions:<br>
Type 5 numbers and click go<br>
The highest of the 5 will appear<br>
It is okay to use a decimal point<br>
Input values:<br>
First<input id="variable1"><br>

Third <input id="variable3"><br>
Fourth<input id="variable4"><br>
Fifth<input id="variable5"><br>
<input type="submit" value="go" onclick="calculate()">

now she wants us to do max <beta and then name the variables with if a<b and I don't know if I put that in the concatenation or what to name my variables! ugh. NOT ASKING TO DO MY HOMEWORK I'm new to programming in general and have had trouble deciding on a good starter project. I've decided to start with something that is (hopefully) pretty simple. I have about a dozen boxes full of vinyl records and would like to write a program to catalogue everything alphabetically by artist using prompts to ask for Album Title, Artist Title, and year. My question at this point is, is JavaScript a good way to do this? I have a fundamental knowledge of HTML, CSS, JavaScript and Ruby. I assumed JS would be the best way (that I know at this point) to do this project, but if I'm wrong, would love to hear it. What I don't understand at this point is how to output the information to a text file, or how to set up an interface to run the scripts. Any advice is very much appreciated. Hi so i am using onClick="myPopup(); on a button and when someone clicks on the button, it pops up an advertisement in a new tab. But is there a way to make the users stay on the page where the button is located instead of forcing the browser to automatically switch to the advertisement tab when a button is clicked? I have written my application by specifying all dimensions in pixels. If used on a monitor with less resolution, it causes the screen to have to scroll left or right. However, it seems to be the same top to bottom. In any event, I was wondering if there is a way to specify pixels maybe through a function or something, where the client's monitor resolution can be detected, and then, if I specify a size as 100px, I can change that to something like pixCount(100). Hi everyone-- I am a fourth grade teacher and I have an idea for a program I could use with my students. I think (key word, I don't know anything about programming) that it should be relatively simple to do. A short description of what the program would do will follow, but my posting is for three main reasons: 1) Is this possible? (I assume it is) 2) As I would be willing to pay for this (up to a certain amount), how much might it cost me if I hired a freelance programmer? 3) Is there anyone out there who would be able to help me with this? Okay, as for the program: it would be a program that would make your own "Jack Attack" (like from the computer game "You Don't Know Jack"). It would give you a place to input up to 10 to 15 keywords (or vocabulary definitions) for the middle and keywords (or vocab words) that would fly past. It would respond to some sort of button input (I'm thinking space bar)....and have an action for wrong answers (buzzer sound) and an action for a right answer (ding! and then move on to next question). Maybe after the game it would give a readout of how many right out of how many possible. It would be really cool to be able to have some background music, maybe manipulate the the colors, fonts, etc. I am wanting to leave the program kind of generic so that I could use this for all sorts of applications: use it for vocabulary words in different subjects, match authors with books, "just for fun" games, maybe even use it for some math facts. Any information you would have is more than appreciated! Thanks for helping a teacher out! Clay Hello all, I am having some trouble getting my Javascript code to work properly. I want to create a program that allows two objects to race to a certain point which is 1000px in my program. I have figured out how to get the images to race at random speed, and I have figured out a function to reset the program if the user chooses to restart. Basically I can't figure out how to get the clearTimeout() to stop the Race() function when it reaches 1000px. I am fairly new to the Javascript world and could really use some suggestions or a point in the right direction. Thanks in advance, AJ. Here is my program so far: <body> <script language="JavaScript" type="text/javascript"> <!-- function StartUp() { if ((car1.style.pixelLeft<1000) && (car2.style.pixelLeft<1000)) { Race(); } else { alert(); } } function Race() { car1.style.pixelLeft+=(Math.floor(Math.random()*11)); car2.style.pixelLeft+=(Math.floor(Math.random()*11)); stop=setTimeout("Race()",50); } function Restart() { clearTimeout(stop); car1.style.pixelLeft=10; car2.style.pixelLeft=10; } function swapImage() { var image = document.getElementById("imageToSwap"); var length = document.getElementById("Road"); image.src = Road.value; } //--> </script> <div id="car1" style="position:absolute; top: 10"> <img src="Car1.gif" alt=""/> </div> <div id="car2" style="position:absolute; top: 75"> <img src="Car2.gif" alt=""/> </div> <img id="imageToSwap" src="Road1000.gif" alt=""/> <form name="form1"> <br> <input type="button" value="Race" onClick="StartUp()"> <input type="button" value="Restart" onClick="Restart()"> <br> Track Length: <select id="Road" name="Road" onChange="swapImage()"> <option value="Road1000.gif">1000 feet</option> <option value="Road750.gif">750 feet</option> <option value="Road500.gif">500 feet</option> <option value="Road250.gif">250 feet</option> </select> </form> </body> Greeting Everyone, Can anyone breakdown the differences between programming languages in VERY VERY BASIC plain English? (i.e. HTML use for website format, CSS used for the graphics on the webpage) Here's what I have questions about: 1. Differences between the most commonly used programming languages for software/web development (Javascript, Ruby on Rails, Phyton, etc.). 2. How do you determine which programming languages to use? 3. What factors are considered? Thank in advance for the people that reply. =) |
