JavaScript - Updating Tag Elements In Designmode
In the code below I have an iframe that acts as a WYSIWYG editor. On load a link is loaded inside the iframe. When you click the link a div opens that displays the URL of that link. Upon changing the link inside the DIV I want to update the href tag that I clicked.
I've experimented with pasteHTML/execCommand("inserthtml") however this only updates the link when you select the text before clicking (as opposed to just clicking on the link), otherwise it inserts a whole new link. I'm trying to get this working across IE, Firefox, Opera, Chrome and Safari. I'd happily pay someone (Paypal) to help me with this. Code: <html>
<body>
<script language="JavaScript">
// Initialize WYSIWYG
function initialise() {
// HTML code to paste
var html = "<a href='http://www.google.com'>Click Me</a>";
if (detectBrowser() == "ie") {
// IE
editorContent.document.designMode='on'; // turn on design mode
editorContent.document.attachEvent("oncontextmenu", showContextMenu); // add listener for context menu
editorContent.document.attachEvent("onclick", showContextMenu); // add listener for context menu
// Paste the HTML code in iframe
document.editorContent.focus();
range = editorContent.document.selection.createRange();
range.pasteHTML(html);
document.editorContent.focus();
} else {
// FF, Saf, Chr, Op
document.getElementById("editorContent").contentDocument.designMode='on'; // turn on design mode
editorContent.document.addEventListener("contextmenu", showContextMenu, true); // add listener for context menu
editorContent.document.addEventListener("click", showContextMenu, true); // add listener for context menu
// Paste the HTML code in iframe
editorContent.focus();
editorContent.document.execCommand("inserthtml", false, html);
editorContent.focus();
}
}
// Show Context Menu
function showContextMenu(e) {
// Get the URL from the clicked link
if (detectBrowser() == "firefox") {
url = e.target.href;
} else {
url = document.getElementById('editorContent').contentWindow.event.srcElement.href;
}
// Set the URL in the pop-up and load it
document.getElementById("theUrl").value = url;
document.getElementById("popUp").style.visibility = 'visible';
document.getElementById("popUp").style.display = '';
if (navigator.appName != "Microsoft Internet Explorer") {
e.stopPropagation();
e.preventDefault();
}
return false;
}
// Update the URL
function updateUrl() {
newUrl = document.getElementById("theUrl").value;
alert('Update the URL to '+newUrl);
/*******************************************/
/* WHAT TO DO HERE TO UPDATE URL IN EDITOR */
/*******************************************/
document.getElementById("popUp").style.visibility = 'hidden';
document.getElementById("popUp").style.display = 'none';
}

function detectBrowser() {
var userAgent = navigator.userAgent;
var browser;
if (userAgent.indexOf("MSIE") !=-1)

Similar TutorialsHi, i have the following html page <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> </head> <body> <input type="text" id="input1" /><br /> <iframe id="textEditor" name="textEditor"> </iframe> <script type="text/javascript"> $(document).ready( function() { textEditor.document.designMode = "on"; textEditor.document.open(); textEditor.document.write('<head><style type="text/css">body{ font-family:arial; font-size:13px;}</style><body>Hi User<br /><br /><span style="font-style:italic;">### Write your message here ###</span><br /><br />Thanks,<br /></body></head>'); document.getElementById("textEditor").contentWindow.addEventListener('focus', OnFocus, true); $("#input1").focus(); } ); function OnFocus() { textEditor.document.body.innerHTML = textEditor.document.body.innerHTML.replace('<span style="font-style:italic;">### Write your message here ###</span>', ""); document.getElementById("textEditor").contentWindow.focus() } </script> </body> </html> Now press on the tab key when the page loads (You should see focus on the textbox field) and you can see that the iframe text editor (WYSIWYG) has no focus... On firefox it works... How can i give it focus on chrome? Hello. I'm creating a simple auto updating script based on PHP and using jQuery to set the interval to 1000 miliseconds. It works in FireFox, as the only one I've tested so far, but in Internet Explorer (Version 7 right now, didn't test others) it just freezes and doesn't auto update. Doesn't auto update either if I refresh the page, so something's messed up here. I'm using the same way of auto updating on other things, such as a chat-page - works on those in all browsers, so I'm kinda on a lost track here. Here's the JavaScript/jQuery: Code: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
function loadContent() {
$('#count').load('counter.php', function() {
setTimeout("loadContent()", 1000);
});
return false;
}
$(loadContent);
And this is what I put on the body of the page: Code: <div id="count"></div> Can anyone see what my problem is? And any workarounds for this? Hi, I am creating a web page which automatically updates one image every 5 seconds. I use ajax to fetch a new img url every 5 seconds, and then update the image by changing img.src. I tested the same (in IE8, firefox) and it worked without any issues in my development server. But, when I try to put it on production server, many people are complaining that they are not able to see any image at all. Code: if (url_received){
var path = url.substring(url.indexOf("/"));
var img = document.getElementById("testimage");
img.src = "/test/media/" + path;
}
I cannot think of a reason why this is failing for others. Is this due to any security issues? If someone helps me out, I would be very thankful. Hi - I am updating a site for a friend as the original designer has gone missing.. I am no developer by any means but know basic html etc.. I want to change a link in the drop down menu.js file, have opened it in my text editor and changed the link that needs changing to a diff page but it isn't updating on the site - arghhh!! I have notice at the top of the page it has: // QuickMenu Pro, Copyright (c) 1998 - 2003, OpenCube Inc. - http://www.opencube.com does this have anything to do with it? I can't find anything on google - any advice is greatly appreciated. Thanks Hi I am making a PC customization website, And I need help wit hthe inputs where you select the parts for the PC. Anyway, I need help for self updating inputs, Like if a user was to select a socket 775 processor, The form would automatically update the motherboard field from --Select a processor-- to a list of socket 775 motherboards. I am quite new at javascript I have never attempted to do anything like this myself, Although I don't know if this would need some PHP in here as well Anyway thanks in advance, Gergy I've done some googling and have come across some information, but I'm not quite sure how to apply it to my problem. I have a PHP page saturna.php with six frames on it using the frameset commands. I would like to somehow make it so that when I click on something in one frame (with one PHP page loaded in it - game.php), it automatically/dynamically updates one of the other PHP pages (inventory.php) in another frame. What will happen is when the thing is clicked on in game.php, an entry will be added to the database, and the second PHP page (which retrieves information from the database) will notice that there is a new relevant record, and will add it to the inventory.php page in the table I have constructed there. From my googling it seems I need to use JavaScript to do this, but I'm not quite sure how - any ideas ? Thanks very much! Hi guys, I've had a little trouble with this and haven't been able to find answers on google. I'm trying to set up a new window that contains a button. Then, if the user clicks the button, the window would display new information accordingly. I have written a simple test that won't seem to work: Code: <html>
<head>
<script language="Javascript" type="text/javascript">
var count = 0;
function Window() {
MyWindow = window.open('', 'myWin', 'height=250,width=250')
MyWindow.document.write('<html>')
MyWindow.document.write('<head>')
MyWindow.document.write('<\/head>')
MyWindow.document.write('<body>')
MyWindow.document.write('<FORM method="post" name="aname">')
MyWindow.document.write('<INPUT type="button" onclick="newfunc()" name="test" value="Click Me"\/>')
MyWindow.document.write('<\/FORM>')
MyWindow.document.write('<\/body>')
MyWindow.document.write('<\/html>')
MyWindow.focus()
}
function newfunc() {
count++
MyWindow.document.write(count)
}
</script>
</head>
<body>
<FORM method="post" name="me">
<INPUT name="opendis" value="Open Window" type="button" onclick="Window()"/>
</body>
</html>
I am probably doing something very wrong. Is there a way for this to work? Thanks! In a form I have two input boxes (ids of return1 and return2) with default values of 0 and a span element (id return3). The span's value is initalized to 0 on page load, and it updates when a button is clicked that calculates x - value of return1 - value of return 2, where x is calculated elsewhere. Form code: Code: Month 1: <input size="7" type="text" value="0" id="return1" name="return_1"> <input type="button" value="Calculate Remaining Amount" onClick="thirdReturn();"> Month 2: <input size="7" type="text" id="return2" value="0" name="return_2"> Month 3: <span style="color:black; font-size:14px;" id="return3"></span> ThirdReturn code: Code: function thirdReturn() {
var first_return = document.getElementById("return1").value;
var second_return = document.getElementById("return2").value;
first_return = first_return.replace(/\,/g,'');
second_return = second_return.replace(/\,/g,'');
var combined = Number(first_return) + Number(second_return);
if (typeof this.remaining_pipp_amount == "undefined") {
alert('Please select a Flex option');
}
else{
if (combined > this.remaining_pipp_amount){
alert('Return Amount Exceeds Credit Amount');
}
else{
var temp = this.remaining_pipp_amount - combined;
var third_return_amount = document.getElementById("return3");
third_return_amount.innerHTML = addCommas(Math.round(temp));
}
}
}
I am trying to change it so that if return2 is zero when the button is clicked, return2 = x - return 1. Here is what I have: Code: function thirdReturn() {
var first_return = document.getElementById("return1").value;
var second_return = document.getElementById("return2").value;
first_return = first_return.replace(/\,/g,'');
second_return = second_return.replace(/\,/g,'');
var combined = Number(first_return) + Number(second_return);
if (typeof this.remaining_pipp_amount == "undefined") {
alert('Please select a Flex option');
}
else{
if (combined > this.remaining_pipp_amount){
alert('Return Amount Exceeds Credit Amount');
}
else{
var temp = this.remaining_pipp_amount - combined;
if (second_return == 0){
var new_second = document.getElementById("return2")
new_second.innerHTML = Math.round(temp);
}
else{
var third_return_amount = document.getElementById("return3");
//alert (temp);
third_return_amount.innerHTML = addCommas(Math.round(temp));
}
}
}
}
Does anyone know why this doesn't work or what can be done to fix it? Thank you! Resolved
Is there any way that I can make my HTML website STAY updated from a javascript innerHTML or value change? I've only used it a little...
Hello Guys, I have a question here.. I have a scroller on my pages that basically reads a text file and displays.. The problem that I am having is it doesn't update until I reload the page(even though the .txt file updates about every 3 minutes).. I would like it to update when the file has been changed.. Here is my page. PHP Code: <link rel="stylesheet" href="../../css/li-scroller.css" type="text/css"> <script src="../../js/jquery.li-scroller.1.0.js" type="text/javascript"></script> <script type="text/javascript" src="../../jquery-1.6.1.min.js"></script> <script type="text/javascript"> $(function(){ $("ul#ticker01").liScroll(); }); </script> <?php $file = file_get_contents ('playingnow.txt'); ?> <div class="scrollpos"> <ul id="ticker01"> <li><a href="#"><?php Echo $file;?></a></li> <!-- eccetera --> </ul> </div> What can I add to make it go out and reload just the div not the entire page? Please advise.. All, first post on the forum. I hope this is relatively simple. I've looked around for the answer, but I thin think the search terms (update onchange event) are a bit too common... Code: document.getElementById("tester").innerHTML= "hello";
document.getElementById("tester").onmouseover = "alert('hello')";
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything. How can I change events? Jason I am fairly new to JS so please have patenience with me. What I am codeing is essentialy some digital signaage for my office. I will have a calender that updates through several screens with information in them. The basic page stays the same but the content is loaded into a large iframe in the center of the page and each html file loaded into the iframe is changed using meta tags. This is a touch screen so I want control along the bottom of the screen. I have did this very crudely with css and html. But I would like to refine it a little more with javascript. I want javascript to control the content of the iframe and javascript to control the buttons along the bottom to manual switch to a diffferent screen along with a button that stops the auto reloading of the page. Here is where I am so far. I have the javascript to automatilly change the iframe src but I need help with the nav buttons and the stop button. Right now the nav buttons are still using the regular <a> tags targeting the iframe. Code: <html lang="en">

I have a website I am currently debugging, http://display.ist-apps.com/. When you select a ski resort, then go on to select a date, the dates relating to that ski resort show. However if you then go back and select another ski resort, the dates do not update they still continue to show the ones from the ski resort you originally selected.

Hello, I'm working with a cooking script that redirects a user if he has already visted the page. Currently, it's set to expire every 24 hours. However, I'd like to have it expire at midnight everyday. How would I change this? Code: <script>
num_days = 24;
function ged(noDays){
var today = new Date();
var expr = new Date(today.getTime() + noDays*60*60*1000);
return expr.toGMTString();
}
function readCookie(cookieName){
var start = document.cookie.indexOf(cookieName);
if (start == -1){
document.cookie = "seenit=yes; expires=" + ged(num_days);
} else {
window.location = go_to;
}
}
var go_to = "/development";
readCookie("seenit");
</script>
I just wrote some javascript with a counter to call an ajax call of many records, but when it is around the 50th record the counter variable is not updating in time for the next ajax call resulting in duplicate results cause ajax is pullin the previous query again
What am I doing wrong here? I am trying to make it where the user can name the link whatever he/she wants.... I think it might be this part... links[i] = name.linkPosition.value; Where linkPosition is a variable. Can I do this? Or is there another way? Code:
<div id="navBar">
<ul>
<li><a href="#" id="link0"><script>document.write(links[0]);</script></a></li>
<li><a href="#" id="link1"><script>document.write(links[1]);</script></a></li>
<li><a href="#" id="link2"><script>document.write(links[2]);</script></a></li>
<li><a href="#" id="link3"><script>document.write(links[3]);</script></a></li>
<li><a href="#" id="link4"><script>document.write(links[4]);</script></a></li>
</ul>
</div><!--end navBar -->
<form>
<label style="color: #FFF;">Change name of links! You can only change them once!</label><br />
<input type="text" class="customLink" size="15" name="link0" onblur="this.value=removeSpaces(this.value);" maxlength="8"/>
<input type="text" class="customLink" size="15" name="link1" onblur="this.value=removeSpaces(this.value);" maxlength="8"/>

changeLink(i);
}
}
function changeLink(number) {
document.getElementById("link"+number).innerHTML="<span style=\"text-transform: capitalize;\">" + links[number] + "</span>";
}

ANY HELP WOULD BE AWESOME!!! I just replaced the functions to look like this... Code: function replaceLinks(name){
for (var i=0; i<=4; i++) {
links[i] = name.linker+i.value;
changeLink(i);
}
}
function changeLink(linkNumber) {
document.getElementById("link"+linkNumber).innerHTML="<span style=\"text-transform: capitalize;\">" + links[linkNumber] + "</span>";
}
Now the links are updating but I get NaN for each link. A noob needs some help. I'm using a combination of Yahoo Pipes and rssdisplayer.js to display some snippets from several RSS feeds on a new site I'm building. The trouble I'm having is that (i) the feeds don't update when I refresh the page, I think because a cached version of the page is being loaded, and (ii) I'd like to have the div containing the feeds auto-refresh at a given time interval. I've got a Twitter javascript working that does both these things, but can't work out how to get the rssdisplayer.js working this way. The rssdisplayer code is: Code: google.load("feeds", "1") //Load Google Ajax Feed API (version 1)
function rssdisplayer(divid, url, feedlimit, showoptions){
this.showoptions=showoptions || "" //get string of options to show ("date" and/or "description")
var feedpointer=new google.feeds.Feed(url) //create new instance of Google Ajax Feed API
feedpointer.setNumEntries(feedlimit) //set number of items to display
document.write('<div id="'+divid+'">Loading feed...</div>')
this.feedcontainer=document.getElementById(divid)
var displayer=this
feedpointer.load(function(r){displayer.formatoutput(r)}) //call Feed.load() to retrieve and output RSS feed
}
rssdisplayer.prototype.formatdate=function(datestr){
var itemdate=new Date(datestr)
return "<span style='color:gray; font-size: 90%'>"+itemdate.toLocaleString()+"</span>"
}
rssdisplayer.prototype.formatoutput=function(result){
if (!result.error){ //if RSS feed successfully fetched
var thefeeds=result.feed.entries //get all feed entries as a JSON array
var rssoutput="<ul>"
for (var i=0; i<thefeeds.length; i++){ //loop through entries
var itemtitle="<a href=\"" + thefeeds[i].link + "\">" + thefeeds[i].title + "</a>"
var itemdate=/date/i.test(this.showoptions)? this.formatdate(thefeeds[i].publishedDate) : ""
var itemdescription=/description/i.test(this.showoptions)? "<br />"+thefeeds[i].content : ""
rssoutput+="<li>" + itemtitle + " " + itemdate + itemdescription + "</li>"
}
rssoutput+="</ul>"
this.feedcontainer.innerHTML=rssoutput
}
else //else, output error
alert("Error fetching feeds: "+result.error.message)
}
//USAGE SYNTAX: new rssdisplayer("divid", "rssurl", numberofitems, "displayoptions")

Novice Javasript query. My requirement: Each time a visitor arrives at a specific webpage i want the main image on the page to be different, or more specifically, one of 6 images which will be shown in rotation. Solution: Set a cookie. Each time the visitor access the page read the cookie and display the corresponding image. Then increment the value and rewrite the cookie, so that next time they'll see the next image in sequence. NB: if the cookie does not exist (first timer) or is at 6, then the value is set to zero (and then incremented). Problem: Can't get my coding to work. Specifically it just doesn't do anything - no error message, no cookie written. I'm a very novice scripter, as in I've cobbled the coding together from bits off the net that i think i've managed to grasp some kind of an understanding of. Very suck it and see - so far lots of sucking and no seeing! Anyway here's my code - if someone could cast a beady eye it would be much appreciated. Hopefully I'm not a million miles out !!! Code:
<script type="text/javascript">
/*<![CDATA[*/
var cookies = document.cookie;
if (cookies.indexOf(pookie) == -1)
{
var pookey = 0;
}
else
{
var startpos = cookies.indexOf(name)+name.length+1;
var endpos = cookies.indexOf(";",startpos)-1;
if (endpos == -2) endpos = cookies.length;
var pookey = cookies.substring(startpos,endpos);
if (pookey == 6) pookey = 0;
}
pookey = pookey++;
var expire = new Date ();
expire.setTime(expire.getTime() + 1000 * 60 * 60 * 24 * 365);
document.cookie = name + "=" + pookie + "; expires=" + expires.toGMTString() + "; path=/";
if (pookey == 1) document.write ("<img src=\"../HomePage/Image1.jpg\" />");
if (pookey == 2) document.write ("<img src=\"../HomePage/Image2.jpg\" />");
if (pookey == 3) document.write ("<img src=\"../HomePage/Image3.jpg\" />");
if (pookey == 4) document.write ("<img src=\"../HomePage/Image4.jpg\" />");
if (pookey == 5) document.write ("<img src=\"../HomePage/Image5.jpg\" />");
if (pookey == 6) document.write ("<img src=\"../HomePage/Image6.jpg\" />");
/*]]>*/
</script>

By updating input name products_data[XXXXXX][purchase_price] or input name products_data[XXXXXX][av_factor] shoul be updates input name products_data[XXXXXX][price] by formula: products_data[XXXXXX][purchase_price] * products_data[XXXXXX][av_factor] = products_data[XXXXXX][price] Because form has alot of integer values for each id: XXXXXX it need to be changes price for exactly id, not all.
