• innerHTML parse for Google Chrome?

  - by user554095

  Hey all. I am adding text to a textArea via Javascript in Chrome (doing it a totally different way in Firefox/IE as Chrome does not support contentWindows). Here is my code: document.getElementById("vB_Editor_001_textarea").value += '<font color="white"><b>' + numberLabel + ':</b> ' + armory + '</font><br/>'; This HTML is getting put directly into the textArea without being parsed. How can I make it parse into regular text with the HTML markup when it hits the textArea? Thanks!

• PHP IF statement not taking variable into account!

  - by Jess

  I have a tabled view in a while loop, where a user can view information on books. For example, book ISBN, book name, read status... Basically, when the user sets their 'readstatus' to 'complete' I want that specific table row to become grey! The logic is very straight forward, however I can't get my IF statement to recognise this: $readstatus = $_GET['readstatus']; if ($readstatus == 'complete') { echo '<tr class="completed">'; } else if ($readstatus != 'complete') { echo '<tr class="reading">'; } I'm obviously doing something wrong here, but all I need is the CSS class of the table row to change if the value of 'readstatus' = 'complete', if not, then output the default CSS table row color ('reading') Should I be putting $result as the variable or something? I have this coming just before my nested IF statement: $result = mysql_query($sql, $connection) or die ("Couldn't perform query $sql <br />".mysql_error()); while($row = mysql_fetch_array($result)) { ?>

• Nested <a> and <span> challenge

  - by PaddyO

  Hi all, Trying in vain to get a nested link working within a nested span. This is a working test page for the code below to explain what I'm trying to do. Any ideas on how to get this working in valid html? I guess it's either a nesting order or style syntax thing but I am at a loss. Any thoughts much appreciated. <div id="greyback"> <ul id="scrollbox"> <li class="listcat">List header</li> <li><a class="menu" href="#freeze">List item 1<span><b>This text has popped up because you have clicked the list item, which has an "a" tag and now has :focus. That "a" tag is the first of two.</b><br><br>What I am trying to do is to set the second "a" tag as a DIFFERENT "embedded" link in this box<span style="color: blue; background-color: yellow;">eg, here<a href="http://www.conservationenterprises.com" target="blank">This is the second (nested) "a" tag in this html nest. It is a link to an external site. Instead of this being an always-visible link, I want it to sit within the yellow box in the first span (click the List item 1 to display).</a></span> </a></span> </li> </a></span> </li> </ul> </div> and the CSS: #scrollbox {margin: 0 auto; margin-top: 1em; margin-bottom: 1em; width:19em; height:auto; max-height: 21em; overflow:auto; border-bottom: 0.1em solid #FFA500; border-top: 0.1em solid #FFA500;} #scrollbox a {float: left; color:#000000; text-decoration:none; width:18em; height: auto; margin-bottom: 0.5em; font-family: Arial, sans-serif; font-size: 0.9em; text-align:left;} #scrollbox a.menu {} #scrollbox a span {display:none; position:absolute; left:0em; top:0;} #scrollbox a span img {float: right; border:0; max-width:7.5em;} #scrollbox a:hover {border: 0; color: #7ebb11; font-size:0.9em;} #scrollbox a:hover span {border: 0; color: #535353;} #scrollbox a span:focus {color: blue;} #scrollbox a:active {border:none; color: #535353; text-decoration: none;} #scrollbox a:focus {border:0em solid #000; outline:0;} #scrollbox a:active span, #scrollbox li a:active span, #scrollbox a:focus span, #scrollbox li a:focus span {display: block; width: 52.5em; min-height: 20em; height: auto; left: 1.5em; top:18em; z-index:10; font-size:0.9em; text-align: left; padding: 1em; padding-bottom: 0em; background-color: #c3FFe3; color: #535353; border: solid #FFA500 0.25em;} #scrollbox li a:active span span, #scrollbox li a:focus span span{display: block; width: auto; height: auto; min-height: 2em; left: 25em; top:10em; z-index:10; font-size:0.9em; text-align: left; padding: 1em; padding-bottom: 0em; background-color: transparent; color: #535353; border: dashed red 1px;} .ul#scrollbox {padding-left: 0.1em;} #scrollbox li {float:left; list-style: none; background: url(blank.png) no-repeat left center; margin-left: 0em; font-family:Arial, sans-serif; font-size: 0.9em;} #scrollbox li.listcat {float: left; text-align:left; width: 18em; margin-left: 0em; margin-top: 0.1em; margin-bottom: 0.3em; padding-top:0.5em; color: green; font-size: 0.9em; font-weight:bold;} Cheers Patrick.

• JQuery selectors select from an html object other than from document root?

  - by orangebrainer

  jQuery selectors select from the document. How do I select from somewhere else other than root? Say I want to select some children from an html object. For this function dothis(obj) { $j("#tabs").removeClass(); $j("#tabs>ul").removeClass(); $j("#tabs>ul>li>a").each(function() { var tabNum = $j(this).attr("href").replace("#", ""); var tabContent = $j("div[id=" + tabNum + "]"); tabContent.removeClass(); $(tabContent).before("<br><h1>" +$j(this).text() + "</h1>\n" ); }); $j("#tabs>ul").each(function() { $j(this).empty();//remove Ul links on top }); } I want to reference the selectors from an html Object (obj) i passed into as argument, instead of selecting from document. Sorry I'm pretty new to jQuery.

• Form Submitting Incorrect Information to MySQL Database

  - by ThatMacLad

  I've created a form that submits data to a MySQL database but the Date, Time, Year and Month fields constantly revert to the exact same date (1st January 1970) despite the fact that when I submit the information to the database the form displays the current date, time etc to me. I've already set it so that the time and date fields automatically display the current time and date. Could someone please help me with this.

• How do I get points on a curve in PHP with log()?

  - by Erick

  I have a graph I am trying to replicate: I have the following PHP code: $sale_price = 25000; $future_val = 5000; $term = 60; $x = $sale_price / $future_val; $pts = array(); $pts[] = array($x,0); for ($i=1; $i<=$term; $i++) { $y = log($x+0.4)+2.5; $pts[] = array($i,$y); echo $y . " <br>\n"; } How do I make the code work to give me the points along the lower line (between the yellow and blue areas)? It doesn't need to be exact, just somewhat close. The formula is: -ln(x+.4)+2.5 I got that by using the Online Function Grapher at http://www.livephysics.com/ Thanks in advance!!

• Creating a PHP web page that enables you to reboot the server in Linux?

  - by Stuart

  I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

• PHP inheriting/extending a particular instance of an Object

  - by delta9

  Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object? This imaginary code should explain what I am wondering: class Base { public $var; function __construct($var){ $this->var = $name; } } class Extender extends Base { function __construct($parent) { parent = $parent; } } $base = new Base('yay!'); $extender = new Extender($base); echo 'Extended base var value: '.$extender->var.'<br/>'; Output (would be): Extended base var value: yay! To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated. I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?
