JavaScript - Highlight Background Color For Text When Page Loads
Hi,
As you will see with the code below when the text ONE and TWO are clicked on it displays a background color. When ONE is activated TWO is off. When TWO is activated ONE is off. But when the page loads I want ONE to display the background color. When ONE displays the background color after the page has loaded, I want to click on TWO to display it's background color and ONE should turn off as it does now. I can't figure out how to activate the background color for ONE when the page loads. Then if it is activated when the page loads, how to turn off ONE and turn on TWO when clicked on and visa versa.

I have some table rows with an item, item description and a text field named "qty" for the quantity. If a user types a number above 0 in the "qty" field, I would like it to highlight the table row. If a user gos back and deletes the number already in the text field I would like the table row to return to it's default state. How can I do this?
I've tried the following: Code: <script type="text/javascript" language="javascript" charset="utf-8">
// <![CDATA[
if ( top.location.href!= window.location.href ) {
document.getElementById( 'bodybg' ).style.background='#12111C';

and Code: <script type="text/javascript" language="javascript" charset="utf-8">
// <![CDATA[
if ( top.location == location ) {
document.getElementById( 'bodybg' ).style.background='#12111C';
}

I've tested the if statement and the set background code, using a button. I'm guessing it fails since there is no background when the script runs. Any ideas? Hi, I created a simple menu: Code: <html>

Was wondering if you knew of a way to keep the button on the mouse-over style for as long as a user is on the page they clicked. This would mean that if a user clicked on a page named 'News', the 'News' button would stay in the mous-over style to indicate which page they were on. Regards Rain Lover Hi, Here's a sample form: Code: <form action="#" method="post"> Name:<br /> <input type="text" name="name" value="your name" /><br /> E-mail:<br /> <input type="text" name="mail" value="your email" /><br /> <input type="submit" value="Send"> </form> When you tab to a text input, the value gets highlighted. How can it be disabled? Any help is appreciated! Mike 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;

Demo: http://theclutch.com/rollover_color_..._bgndimage.htm 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, On my webpage I have an embedded link that jumps the users up to a text box for logging in. I'm trying to find a way so when they click that link, it will not only jump up to the text box but highlights it as well. I then want the highlight color to fade back to normal. I've been searching around but I can't find something that will work. Any ideas? Hi all, Please forgive me if this is a dumb question. Is it possible to highlight the contents of all text and/or textareas within one form simultaneously? I've tried to do it using the funciton below, it cycles through allright, but only highlights each field whilst it is in focus, then loses it when it moves to the next field. The result is that only the last text/textarea within the form is highlighted. My aim is to highlight all fields for subsequent spell checking. Any help would be appreciated. Code:
<html>
<head>
<script type="text/javascript">
function SelectText(){
var fields = document.getElementsByTagName("input");
for (var i = 0; i < fields.length; i++){
var node = fields[i];
if (node.getAttribute('type') == "text"){
node.focus();
node.select();
}
}
}

Hi, I am having trouble searching for text in a textarea in all browsers. I display formatted text in a textarea with tinyMCE editor. Some of the text contains blanks ('______') which the user needs to find and fill in (usually with a number). I have written a new button on the toolbar of the editor which will find and highlight the blank when clicked. The user will click the button, fill in the text, click the button, fill in the text, etc. In IE the blanks are highlighted just fine. The only problem is: user clicks button and first blank is highlighted. User fills in the text then clicks the button again. Second blank should be highlighted but it skips right to the third blank. If you don't fill anything in, the next blank will be highlighted. If you highlight and then fill anything in, the next blank is skipped and the following blank is highlighted. Any thoughts? But my worst problem is with Mozilla. I get an error. It does not act like setSelectionRange(pos, pos+len(str)) is a valid function call. I receive the following error: "component returned failure code: 0x800004005 (NS_ERROR_FAILURE)[nsIDOMNSHTML TextareElement.setSelectionRange]" Here is my function: var win = window; var n = 0; var str = '______'; function FindBlanks() { var txt, i, found; win = tinyMCE.get('txtPolicy').getDoc(); if (str == "") return false; if (window.execScript) { txt = win.body.createTextRange(); //Find the nth match from the top of the page for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) { txt.moveStart("character", 1); txt.moveEnd("textedit"); } // If found, mark it and scroll it into view if (found) { txt.moveStart("character", -1); txt.findText(str); txt.select(); txt.scrollIntoView(); // n = i--; n++; } //Otherwise, start over at the top of the page and find first match else { if (n > 0) { n = 0; alert("End of document has been reached."); } //Not found anywhere, give message. else alert("No blanks found."); } } else { //document.getElementById('txtPolicy').setFocus; var ht = '______'; if (ht.length == 0) { alert('highlightText has zero lenth'); return false; } var str2 = document.getElementById('txtPolicy').value; var startPos = str2.indexOf(ht); if (startPos == -1) { alert('No blanks found'); return false; } document.getElementById('txtPolicy').focus(); document.getElementById('txtPolicy').setSelectionRange(startPos, startPos + ht.length); return true; if (n == 0) alert ("No blanks found."); } return false; } Can anyone help me with this? Thanks. Resolved
i have a javascript bookmark to log me onto my schools site javascript: window.location.href="http://www.MySchool";login=document.getElementById('Login'); void(login.value='user'); pass=document.getElementById('pass');void(pass.value='pass'); LoginbuttonSubmit(); without window.location.href="http://www.MySchool" it works fine if the page is already open, but with using the link to open the page, it runs the remaning script before the page loads and it doesn't work. is there any way to fix this withou using setTimeout() Hey guys, hope this is in the right place... Basically I was wondering if anyone could point me in the right direction or to an example of where a div slides onto the screen as soon as a page loads. My client wants something like this: http://www.nytimes.com/packages/html...ion/index.html (without parallax or the fade-in) but I refuse to do it in Flash, obviously. I have this gallery he http://juicenothing.com/freelance/gallery.php The div id is wrap. Is this possible? I can't find a good example anywhere!! Thanks (i'm a bit of a n00b, so pls go easy on me ) This might be a little complicated. I'll try to be as clear as possible. I got some help from Old Pedant a little while ago and the code worked great. The problem came after I tried some code that will highlight (select) text in a DIV: Code: <script type="text/javascript">
function selectNode (node) {
var selection, range, doc, win;
if ((doc = node.ownerDocument) && (win = doc.defaultView) && typeof
win.getSelection != 'undefined' && typeof doc.createRange != 'undefined'
&& (selection = window.getSelection()) && typeof
selection.removeAllRanges != 'undefined') {
range = doc.createRange();
range.selectNode(node);
selection.removeAllRanges();
selection.addRange(range);
}
else if (document.body && typeof document.body.createTextRange !=
'undefined' && (range = document.body.createTextRange())) {
range.moveToElementText(node);
range.select();
}
}
</script>
Code: <div id="bb1"></div>
<form>
<input type="button" value="Click Here to Highlight Data" onclick="window.selectNode(document.getElementById('bb1'));" style="margin-left:4px; font-weight:bold; font-family: Verdana, Arial, Helvetica, sans-serif; font-size:14px;">
</form>
It works great with Firefox and Internet Explorer, but there is a problem with Opera. The contents of the DIV is selected, but so is everything after the DIV. Below is a link to the page, but be sure to turn down your speaker volume before you visit the page so you won't have a heart attack: http://www.randomterrain.com/atari-2...music-toy.html The DIV is empty when the page loads. To put content in the DIV, jump down to All Sounds and left click on a couple of the numbers than run from 0 to 31, then jump down to the DIV. When you click on the "Click Here to Highlight Data" button, you'll see that more than the contents of the DIV is selected. I hope someone can figure out how to make the code work properly with Opera. Thanks. I am working with using Javascript to create a page that scales and keeps its aspect ratio (much like a Flash page would). After a lot of trial and error, I have a prototype up with a couple of problems. It loads correctly once in I.E. Reloading, or opening a new browser, will also load the page correctly. But visiting a different page and coming back causes the width attributes to break. This happens with the non-aspect-ratio version in pure HTML also, but I was hoping that this problem would be solved by establishing values based on javascript variables. As for Firefox, the problem is more or less exactly the opposite. The page loads up all wonky the first time, and a reload or resize will fix it for every time afterward. To see what I'm talking about, you can take a look at http://www.jonesmfgmusic.com/testpag...lem_width.html For the HTML only version, see http://www.jonesmfgmusic.com/testpag...blem_html.html I'm guessing this is something to do with the order in which the data is loaded, so that once the information is all cached, it stops functioning in IE, and starts functioning in FF... can anyone confirm whether I'm on the right track with that, or how to fix it if I am? I'm most concerned by the fact that the width attribute is behaving as it does in IE. That looks like some kind of Microsoft bug to me, and I need a way around it. As for Firefox, I am guessing if I can just get it to load all of the correct information ahead of time, the page should come up correctly, but I just can't think how to do that. Does anyone know what's wrong with this code because when the page loads, the link is not being hidden Code: window.onload = setTarget;
function setTarget()
{
var theLinks = document.getElementsByTagName('a');
for(var i = 0; i < theLinks.length; i++)
{
if(theLinks[i].getAttribute('href') == '/subjects/new')
{
theLinks[i].style.display = "none";
}
}
}
So I am having a bit of a weird issue. I am trying to make a webpage compatible with IE8 and it's quite painful. The page works great in firefox and chrome, but in IE8 it only loads some of the time. About 60% of the time the page loads and executes properly, but the other 40% of the time it looks like it hits an error somewhere and doesn't finish loading. I have tried using the IE error console / debugger (by pressing F12), but I can't seem to find any information about why the page isn't loading properly. The page that I am working on is located he http://tinyurl.com/89anxbd The page uses an SVG based UI, and in order to make this compatible with <= IE8 I am using SVGWeb to render the SVG code as flash for IE8 users. For Firefox, and other browser-compliant users the SVG code is rendered natively in the browser. Here is an image of what the page should look like (when it does load correctly in IE8): Here is an image of what the page looks like when it fails to load: It is like the page defines the circle elements for the various cities, but has not yet rendered the provinces (which are defined above the cities in the HTML body), but I'm not 100% sure on this. Any help is much appreciated! Hi all I have created a single page horizontally scrolling website comprised of 5 sections with a fixed navigation bar in the top right of the screen at http://www.clickmunki.com and I am trying to figure out how to highlight the active section of the site in the nav bar as the user navigates through the site so that the user knows exactly which section of the site they are in. I assumed this would be a pretty basic thing to try and do but I have not been able to achieve it so far. I have tried a few different methods but no success as yet. Can anyone point me in the right direction as to how best achieve this? Can I do it just using css or would i need some js?

I have a slow loading external JavaScript that displays a calendar widget. When I put it in my sidebar, while the page loads, it cuts off where the calendar should be until the JavaScript for it finishes. How can I make the script load after the page finishes loading? I tried creating a function at the end of the HTML and calling the function in the sidebar, but I think because the function was being called before the script was executed, it didn't work. I appreciate any and all help! Hi. I am very new to javascript, so I might not even be wording my question right, but I am going to try and be as concise and specific as possible. I am using jquery on my website- the galleria plugin- to make a slideshow. you can see the completed show he http://www.pauljameswilliams.com/demo2a.html This slideshow will be one of three on my website. Each slide show will opperate the same exact way.I have built in tabbed navifation, and the slideshows will all be accessable under the "portfolio" tab by clicking on their corresponding links. check out the site he http://www.pauljameswilliams.com/portfolio.html As it is I have one slideshow up, although not yet connected to the corresponding link, but the images won't load. My guess is that because the div tag is hidden that the contents don't load propperly and I need the contents to load when the corresponding div tag that it is contained in becomes visible but I don't know how to do that. this is the javascript that I have written to show/hide the <div> tags where the content will live. Three slide shows will live in content_2 and show/hide when the corresponding button is pressed. Code: function tabSwitch(new_tab, new_content) {
document.getElementById('content_1').style.display = 'none';
document.getElementById('content_2').style.display = 'none';
document.getElementById('content_3').style.display = 'none';
document.getElementById('content_4').style.display = 'none';
document.getElementById(new_content).style.display = 'block';
document.getElementById('btn_1').className = '';
document.getElementById('btn_2').className = '';
document.getElementById('btn_3').className = '';
document.getElementById('btn_4').className = '';
document.getElementById(new_tab).className = 'current';
}
thank you- I am really stuck. i promise, i am actually learning javascript, I'm not just trying to get other people to do my work for me. |
