JavaScript - Dynamic Content Confusion
Why does...
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html><head><title></title>
<script language = "javascript">
function start() {document.writeln (testPara.innerHTML = "Object reassignment");}
</script></head>
<body onload="start()">
<p id="testPara">Paragraph</p>
</body></html>
... only produce the output "Object reassignment"? After the onload event fires to execute the document.writeln method, isn't <body> processed to output the "testPara" object, now redefined, a 2nd time? Why does it not? What am I missing? Similar TutorialsHi all, I am using xmlhttp.open();xmlhttp.send(); to send a php content to a div. This php content is again using the same method to get php content from a further page. The content of the div, does not seem to be using the css and javascript files defined in the calling pages <head> section. Does anyone know why this is? Is there a workaround or solution to this problem? It might be easier to understand looking at the code, so Background info: Javascript file: scripts.js client.php ----> loads data from: display_client.php display_client.php ----> loads data from: display_brand.php Code: client.php http://pastebin.com/4EFn9YRf display_client.php http://pastebin.com/BGZAKre2 display_brand.php http://pastebin.com/0a4Pg3gg scripts.js http://pastebin.com/er4dkmPc Thanks! Hello there, new to this forum and starting with a quick question. Normaly I can figure things out myself but I'm a bit stuck on this one. I have two scripts. one is for TinyMCE (WYZIWYG editor): Code: tinyMCE.init({
mode : "textareas",
theme : "advanced",
plugins : "pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
// Theme options - button# indicated the row# only
theme_advanced_buttons1 : "newdocument,save,|,styleprops,del,ins,attribs,|,visualaid,visualchars,template,pagebreak,|,preview,cleanup,code,print,|,|,help,fullscreen",
theme_advanced_buttons2 : "insertlayer,absolute,moveforward,movebackward,|,tablecontrols,|,hr,advhr,,charmapemotions,iespell,media,ltr,rtl,anchor,image,nonbreaking,|,insertdate,inserttime",
theme_advanced_buttons3 : "bold,italic,underline,strikethrough,|,outdent,indent,|,bullist,numlist,|,sub,sup,|,styleselect,formatselect,fontselect,fontsizeselect",
theme_advanced_buttons4 : "undo,redo,|,cut,copy,paste,|,pastetext,pasteword,|,search,replace,|,forecolor,backcolor,|,justifyleft,justifycenter,justifyright,justifyfull,|,blockquote,cite,|,abbr,acronym,|,link,unlink,|,removeformat",
content_css : '/CSS/TinyMCE.css',
theme_advanced_styles : "Test style=header1;",
theme_advanced_toolbar_location : "top",
theme_advanced_toolbar_align : "left",
theme_advanced_statusbar_location : "bottom",
theme_advanced_resizing : true,
});
function setup() {
tinyMCE.init({
mode : "textareas",
theme : "advanced",
plugins : "pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",

first part loads tinymce when it's there on the page, second part loads it when a button is pushed. second script is for loading filecontent into a div: Code: function load_this(url) {
if (window.XMLHttpRequest) { // Non-IE browsers
req = new XMLHttpRequest();
req.onreadystatechange = targetDiv;
try {
req.open("GET", url, true);
} catch (e) {
alert(e);
}
req.send(null);
} else if (window.ActiveXObject) { // IE
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = targetDiv;
req.open("GET", url, true);
req.send();
}
}
}
function targetDiv() {
if (req.readyState == 4) { // Complete
if (req.status == 200) { // OK response
document.getElementById("main").innerHTML = req.responseText;
} else {
alert("Problem: " + req.statusText);
}
}
}
now the problem: I have this page with div 'main'. an url loads this script, but after loading the dynamic content into the div, the setup() script isn't working: Code: function load_editor(url) {
load_this(url);
setup();
}
where url=editor.php. The funny thing is: when I click the button to load the content into the div, the textarea (from editor.php) loads, but the javascript function to start tinymce isn't working! This is probably because right after loading the div with 'editor.php' the setup() script doens't recognise the freshly loaded content. However, when I place a link in 'editor.php' which calls javascript:setup(); and click it after loading the content, setup() does work. my question: How can I make it so, that, when I press a link or button to load the editor.php into a div, the setup() script recognises the fresh code and starts the WYSIWYG editor? Do I have to use state ready or something? And ifso, how do I do this? Or is there some other way I can do this? Kind regards and many thanks for your help! Kevin Hi, Here's what I've been trying a lot to find but to no avail: a simple text field and submit button that lets users insert an embedding (HTML/CSS/JavaScript codes) to display on the same frame. I'd like something like this: http://www.howtocreate.co.uk/tutoria...s/dywrite.html Unfortunately it doesn't run any code, e.g. Code: <html>
<head>
<script type="text/javascript">
function startTime()
{
var today=new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
// add a zero in front of numbers<10
m=checkTime(m);
s=checkTime(s);
document.getElementById('txt').innerHTML=h+":"+m+":"+s;
t=setTimeout('startTime()',500);
}
function checkTime(i)
{
if (i<10)
{
i="0" + i;
}
return i;
}
</script>
</head>
<body onload="startTime()">
<div id="txt"></div>
</body>
</html>
Or the text marquee code on the following tutorial: http://www.dynamicdrive.com/dynamicindex2/cmarquee.htm Your help is greatly appreciated! Regards Rain Lover Hello Friend, I am using a javascript code installed with Dreamweaver for this page: http://www.alpinelakesair.com/newsite/charters.php When you open the page, (the script element is on the right), the first tab is already open. I would like none of the tabs to be open, so that you have to first click on a tab to open it. Also, when you start clicking on the tabs, a blue focus ring surrounds the active elements. I do not like the blue focus ring. Finally, you may notice that when you click on the tabs there is a slight jumping action that takes place among the tabs, a slight skip before the tab starts sliding up. So my questions a 1. how to not have any tabs open from the start. 2. how to get rid of the blue focus ring. (if you are seeing it) 3. not a big deal, but it would be nice to get rid of that skipping action so the sliding elements moved smoothly. My HTML is: Code: <div id="Accordion1" class="Accordion" tabindex="0">
<div class="AccordionPanel">
<div class="AccordionPanelTab">DHC-3 Turbo Otter Charter Rate</div>

Thank you very much to whomever can help. and by the way I have no knowledge in javascript. Alex I need help with my divs and dynamic content. I would like my "menu" div (which includes a menu.html and menu.css file) to link to my "middle" div. Here is what I would like to accomplish: Screenshot And this is what I've got: My website I'm using this code to implement my pages into the "middle" div. Is there a way to target my "middle" div from an external menu.html page? Or is there a better way to do this? Hi all, I'm not sure if this is a Javascript question or PHP, so if it needs to be moved can an admin please do so... Anyway, basically I have the following code: Code: <a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">View Availability</a>
This pops up a divs with a black alpha background, so that it appears the new content is displaying over the top of the current content. This all works fine, however the content I am displaying in the top level div is (or should be) dynamic. In order for the content to be useful I need to grab the id. Normally I would simply do this: Code: <a href = "url.php?uniqueidentifier=<?php echo $row['id'];?>" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">View Availability</a>
However what happens in this instance is that the page loads with the javascript and the id in the url but it then disappears... Has anyone got any ideas on how I might be able to get around this? Many thanks, Greens85 I'm working on my portfolio and I want to get content to load into my "middle" div upon clicking on the buttons in the sidebar. I'm able to get it to load, but I can't figure out how to get the CSS to load. I keep getting errors in the code. Here is the code I'm using: http://www.dynamicdrive.com/dynamici...jaxcontent.htm Here is what I've got: Code: <img src="images/rule.png" id="rule" width="1" height="1" />
<a href="javascript:ajaxpage('about.html', 'middle');"><img src="images/about.png" width="195" height="101" alt="about" /></a>
<img src="images/rule.png" id="sidebar_rule" width="194" height="1" />
<a href="javascript:ajaxpage('work.html', 'middle');"><img src="images/work.png" width="195" height="101" alt="work" />
<img src="images/rule.png" id="sidebar_rule" width="194" height="1" />
<img src="images/resume.png" width="195" height="101" alt="resume" />
<img src="images/rule.png" id="sidebar_rule" width="194" height="1" />
<a href="javascript:ajaxpage('contact.html', 'middle'); loadobjs('contact.css', 'feature.js')"><img src="images/contact.png" width="195" height="101" alt="contact" /></a>
<img src="images/rule.png" id="sidebar_rule" width="194" height="1" /></div>
I'm working on the contact page right now, just trying to figure out how to get it to load properly. Here is a screenshot of what it's supposed to look like: https://skitch.com/jillianadriana/r7...itled-document I can't get it to load with the custom CSS. Hi All, I'm working on a javascript-only application that queries an in-memory database, at times requests (all internal to the JS app) are lengthy, so I need to post a "Processing..." overlay atop the clicked UI tab to provide user feedback that something is actually happening. For the life of me I cannot figure out how to push the "Processing..." content to the screen while the DB lookup is underway. It appears that there's only one shot at updating the display, and that's when all JS processing has concluded (ie, the data has been looked up and is displayed). Any tips would be greatly appreciated, what I wish to do may not be possible? Thanks in advance for your assistance! JD Hi, all! I'm a "fresh" newbie, JS self-taught from the great resources provided in this forum. I want to better currently working page but lack enough knowledge atm. The situation is this: * Multimedia database - audio clips and corresponding video clips to some of the audio ones. * Dynamic content page showing the latest (by date) 5 or 10 clips with their info from db. * Links provided for each clip, both to listen in a new popup window and to download the clip. Accomplished so far: everything of the above *only* for the audio clips (and video ones but separately on a different page). Every record in the data base has an audio clip and some of them, not all, have a video clip. E.g. there are records only with audio clips and there are records both with audio and video clips. My question is is it possible wherever there's a video clip in the db in an already displayed db-record on the page to display 'watch' and 'download' icon for it together with already shown audio icons ('listen' and 'download')? Conditional displaying. I read about combination between JS and CSS in almost similar situation but don't know how to apply it in my situation due to my little knowledge base at this moment. So, any help will be highly appreciated and useful as it will push me forward in learning JS. I'm almost sure this is possible as it's not a complicated issue. I can post my so far working code, if requested. If not provided enough info on the issue, let me know. Thank you in advance! I'd like to place an AJAX call to load another SELECT menu in my form, and I'm having trouble finding a tutorial. Can someone point me to a good tute, or provide some guidance/examples here? For your Copying/Pasting pleasure , here's an example button for which I'd include the onclick(): Code: <button type="button" >Add</button> And here's an example SELECT menu: Code: <select id="idNumber" name="weekday_1['workPeriod_new'][] > <option value="1" >one</option> <option value="2" >2</option> </select> Thanks-a-bunch, ~ Mo NOTE: Overall, I'm pretty green in JS. Hello, I'm working on a set of animation code for school and I keep getting an error like this: Uncaught SyntaxError: Unexpected token ILLEGAL on line 25 of the code. What am I missing and/or what is out of place? Code: var canvas;
var context;
var CanvasWidth = 0;
var CanvasHeight = 0;
var FPS = 60;
var x = 0;
var y = 0;
var background;
var critter = [];
window.onload = init;
function init()
{
canvas = document.getElementById("myCanvas");
context = canvas.getContext("2d");
CanvasWidth = canvas.width;
CanvasHeight = canvas.height;
background = new Background();
for (var i = 0; i < 6; i++);
}
{
critter[i] = new Critter();
}

function Background ()
{
var obj ={};
obj.draw = function()
{
context.clearRect(0, 0, CanvasWidth, CanvasHeight);
var gradient = context.createLinearGradient(0, 0, 0, CanvasHeight);
gradient.addColorStop(0.0, "#C0F5E7");
gradient.addColorStop(0.8, "#3F43E7");
gradient.addColorStop(0.81, "#AF8553");
gradient.addColorStop(1.0, "#E6CBAB");
setInterval(loop, 1000/FPS );
context.fillStyle = gradient;
context.fillRect(0, 0, CanvasWidth, CanvasHeight);
};
return obj;
}
function Critter() {
var obj = {};
obj.x = 0;
obj.y = 0;
obj.vx = Math.random() * 2 - 1;
obj.vy = Math.random() * 2 - 1;
obj.update = function()
{
obj.x += obj.vx;
obj.y += obj.vy;
}
function bounds()
{
if (obj.x > canvas.width)
{
obj.x = Math.random() * 2 - 1;
obj.y = Math.random() * 2 - 1;
obj.x += obj.vx;
obj.y += obj.vy;
}
}
obj.draw = function()
{
context.fillStyle="#AA0000";
context.fillRect(obj.x, obj.y, 25 , 25);
};
}
}
function draw()
{
context.clearRect(0, 0, CanvasWidth, CanvasHeight);
background.draw();
for (var i = 0; i < critter.length-1; i++)
{
critter[i].draw();
}

Can anyone tell me how the following code actually works please? I've been trying to work out exactly why I need it all, but can't understand it at all! Code: var speed = 50
var myInterval
var pause
function start(){
window.clearInterval(pause)
myInterval = setInterval("auto()",speed)
}
pause = setInterval("start()",3000)
The body onLoad is set to run start(). If anyone can explain why this code is needed I would be very greatful. This is some code that I found that does what I need to do. However in this code I need to create a new var for each item. I have a lot of item in my list that I want to add to the drop down. Is there a simpler way to do this in JS? Cheers Daniel.

Can anyone tell me why the string comparison test doesn't work in this javascript function? It works if you use just text between the currentItem div tags, but not when you use html for an image. I even tried to use iso characters instead of angle brackets, as in "<img src=expand.png></img>" and still no dice. Why not? Code: <html>
<head></head>
<body>
<script language="JavaScript">
function toggleValue()
{
if(document.getElementById("currentItem").innerHTML != "<img src=expand.png></img>")
{
document.getElementById("currentItem").innerHTML = "<img src=expand.png></img>";
}else
{
document.getElementById("currentItem").innerHTML = "<img src=collapse.png></img>";
}
}
//-->
</script>
<table width =" 200" border="0">
<tr>
<td colspan=2><br><center>
<a href="javascript:toggleValue()">Toggle Value</a>
</center></td>
</tr>
<tr>

<strong>Value:</strong>

Thanks, Neil please pardon my ignorance, but I'm clueless as to why this won't work.... the following is in the header of my page. The first part is the "menu" of the page, the second ( <script type="text/javascript" src="rotate1.js.js"> ) is an external script that rotates an image on the page..... the 2nd works perfectly in a page by itself, but when I insert it in the template with the menu script, images won't rotate. I know I'm missing something that tells the 2nd script to run, but I just don't know what it is? I'm just frustrated with myself that I can't figure it out and i've read so many forums/tutorials/helps that I've only succeeded in confusing myself further! HA! i apologize again for my ignorance... last time i did a web site was 8 years ago, but my boss is paying me to get this done and I REALLY need to pay my phone bill this week!!! Code: <script language="Javascript">
<!--
<!--
function gotoURL(u)
{
document.location = u;
}
function turnon(i)
{
if (document.getElementById || (document.all && !document.GetElementById))
i.style.backgroundColor = "#baccfc";
i.style.textColor
}
function turnoff(i)

Thanks in advance for ANY advice you may have!!!! Hi all, I am a little stuck trying to use arrays for the purpose of creating a currency converter. I have created the script below but it seem to work fine without the arrays added in. Any ideas? <script type="text/javascript"> function currencyConverter() { //declare and initialise variables var CurrYen = 128.7; var CurrUSDollar = 1.59; var CurrEuro = 1.15; var CurrSwissFrank = 2.06; var CurrDanishKorona = 9.69; var strCurrency = new Array(5); var dblExchange = new Array(5); var dblGross var dblCurrency //collect information from drop-down menu and text boxes strCurrency = document.getElementById("cmbCurrency").value; intSterling = document.getElementById("txtSterling").value //selection if (strCurrency == "Yen") { dblCurrency = CurrYen; } else if (strCurrency == "US Dollar") { dblCurrency = CurrUSDollar; } else if (strCurrency == "Euro") { dblCurrency = CurrEuro; } else if (strCurrency == "Swiss Frank") { dblCurrency = CurrSwissFrank; } else if (strCurrency == "Danish Korona") { dblCurrency = CurrDanishKorona; } else { dblCurrency = 0; } //calculate total currency to convert dblGross = dblCurrency * intSterling; //display total cost document.getElementById("txtSterling").value = dblGross.toFixed(2); } </SCRIPT> Hello I'm having a very simple RegExp problem. I have the text: Code: sddsfdfs[br][CARET][br]<i>[/quote]</i></div> And I want to match it against a Javascript RegExp: \[br\].*?\[\/quote\]<\/i> Note I used to the non-greedy quantifier ( ? ) for .* , such that it should match the minimum. I am expecting it therefore to match the first in the quote below, but instead it is matching the second: Code: 1. [br]<i>[/quote]</i> ------------------------------------------------- 2. [br][CARET][br]<i>[/quote]</i> I'm sure I've just missed something, I'd very grateful if someone could point out what this is? Thanks Alright, so I've been writing a plain javascript file, which is called by HTML later to grab information from a certain page and then parse through that information. This is being done as a Windows Gadget, so the "browser" is IE. I have two main problems with this: One is caching. I can't get not caching to work at all. I've tried headers and I've tried putting something random at the end of the URL. The randomness at the end of the URL works when done from an HTML file embedded with Javascript but will not work from a pure Javascript file. My other, potentially bigger, problem is that the xmlhttp object does not seem to ever want to open again. I'm pretty sure what's happening is it doesn't get back into ready state 4. That is, unless I run an html file that accesses the same url. Then, suddenly, the gadget runs its update function and it actually decides to work. The gadget still runs the update function otherwise but it doesn't actually do anything, which is I believe caused by it never getting back to ready state 4 on its own. I appreciate any help on this, and if I didn't explain anything clearly I'm more than happy to clarify. Cheers. Can someone tel me the code to put a dropdown box showing default values as shown below using script ..i,e by enclosing them in document.write in script <CODE> <SELECT NAME="choice" > <OPTION VALUE="1">one </OPTION > <OPTION VALUE="2">two </OPTION > <OPTION SELECTED VALUE=" 5 "> 5 </OPTION> </SELECT> </CODE> |
