JavaScript - Need To Change Width="" Attribute Not Style.width Please Help -
Need to set the width of a Table that is being spit out by this god awful CMS...
please help me... change the html attribute width! Similar TutorialsHello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hi, Im working on my ad script and im having an issue with my text ad. The js seems to work fine for the <a tag up and down the finger dissappears, but if you move the pointer right the <a is active all the way. And im not sure why. temp file for testing test link removed, fixed the issue thanks move the pointer up and down and side to side and watch the pointer, up and down is fine but right is active. Why? I'm writing divs to a page that will be used to hold images of various sizes, so I'm setting the width to auto. However, some of the images will need captions, and with the auto width, the div is widening to accommodate the size of the text, rather than sizing to the image and wrapping the text. I could wait for the image to load and base the div width on imageobject.width, but waiting for a image.onload is screwing with the rest of my code. Rather than roto-rooting my code to make the image.onload work, I thought I'd ask if anyone had ideas on making a div auto-size to an image while constraining text in the same (or maybe a child?) div. Lemme know your thoughts! Thanks! ~gyz Hi, I'm working on a bit of JavaScript that will read the source and other information from an img tag for some CSS manipulation. So basically I'm using getElementById with a workaround for the IE failings with that method. var myImage = document.getElementById("myLogo"); Then I grab the attributes by name with: var imageattributes=myImage.attributes; var imgURL = imageattributes.getNamedItem("src").value; var imgHeight = imageattributes.getNamedItem("height"); var imgWidth = imageattributes.getNamedItem("width"); var imgAlt = imageattributes.getNamedItem("alt"); It all works great in IE8 and FireFox. The alt and src work great in everything. However IE 6 and 7 (and compatibility view IE8) always return "0" as the value for height and width even when another value is set. They return "0" when the tags aren't included at all. I did a google search but I couldn't find anything about this specific IE bug, assuming it's a bug and not something I'm overlooking. Anyone have any tips or similar experiences? Thanks, Heather I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}
function chkrads(rbGroupName) {
var ExPg = [
[0,''],
[100,"1 extra page"],
[200,"2 extra pages"],
[250,"3 extra pages"],
[300,"4 extra pages"],
[350,"5 extra pages"]
];
var ExEm = [
[0,''],
[10,"1 extra email"],
[20,"2 extra emails"],
[30,"3 extra emails"],
[40,"4 extra emails"],
[50,"5 extra emails"]
];
var ImgBun = [
[0,''],
[10,"3 extra image"],
[20,"5 extra images"],
[30,"7 extra images"],
[40,"10 extra images"]
];
var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
var totalprice = 0;
var tmp = ''; var items = [];
for (var i=0; i<rbtnGroupNames.length; i++) {
tmp = getRBtnName(rbtnGroupNames[i]);
if (tmp != -1) {
switch (i) {
case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
}
}
}
document.getElementById('QUOTED_PRICE').value = totalprice;
document.getElementById('ITEMS_SELECTED').value = items.join('\n');
document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}
function validate() {
// add any required validation code here prior to submitting form
var allOK = true;
// if any errors found, then set 'allOk' to false;
return false;
// after testing with validation code, change line above to: return allOK;
}
</script>
And then the <body> Code: <form name="radio_buttons_startup" id="radio_buttons_startup">

Thanks for your help in advance! I was under the impression that you can always access any element on a webpage very easily by assigning a value to the "id" attribute. It seems this is true in the Chrome browser but not in the Opera Browser. My God I can't believe how much disarray the state of programming is in when it comes to certain things working in certain browsers...What's the HTML5 standard on this situation...in other words what does the ECMAScript standard say is the proper implementation? Code: <!DOCTYPE html>

Should you be able to access any webpage element by simply specifying the value of it's 'id' attribute? Chrome says 'yes'. Opera says 'no can do'. I get a 'Uncaught Exception;ReferenceError:Undefined variable' error message in the Opera debugger window. The exact same .html document throws no exceptions in the Chrome(version 18) browser. Hi, There is a live search on my web page but the box of available options which falls below the 'input' field has a transparent background color. How can it be changed to non-transparent? This line below makes the background white, but all the text on the page shines through, since the default is transparent. [CODE] document.getElementById("linksearch").style.backgroundColor="#FFFFFF"; [CODE] This instruction line does not help much 'cos I can't figure out the correct way to make it work: [CODE] Object.style.backgroundColor="color|inherit|transparent". [CODE] Thanks. Hi and thanks in advance! Someone on this site made a form for me that hides and displays fields, depending on which variable is chosen from a given array. They did a very good job with it with one exception. It seems the code that is used to hide certain fields also hides the form data rather than posting it when the form is submitted.

Sorry for all the code! Is there anything I can do to maintain the hide and seek nature of the forms and show the data that is submitted, or am I stuck displaying all fields all the time? Hi there, can anyone let me know how to add an "ALT" tag to this bit of javascript? myimages[1]="html/images/cat-image-10.jpg" Cheers Quote: <html> <head> <script type="text/javascript"> var a = january var b = febuary var c = march function test() { document.getElementById("test").innerHTML=a; <!-- needs to be A on first function click, b on second, c on third, etc..^^--> } </script> </head> <body> <p id="test"></p> <!-- the <p> should go to next month upon each function --> <input type="button" value="asdf" onclick="test()" /> </body> </html> I tried to explain it pretty well in the comment tags, thanks! I need to change input type="text" to input type="password" via JavaScript Code: <form id="login" action="#" method="post"> <input id="username-field" type="text" name="username" title="Username" onmousedown="javascript:this.value=''; javascript:this.focus();" value="Username" tabindex="1" /> <input id="password-field" type="text" name="password" title="Password" onmousedown="javascript:this.value=''; javascript:this.type='password'; javascript:this.focus();" value="Password" tabindex="2" /> <input type="submit" name="submit" value="sign in" tabindex="3" /> </form> This works in Firefox and Safari but not IE So then I tried this code Code: <script type="text/javascript">
function passit(ip){
var np=ip.cloneNode(true);
np.type='password';
if(np.value!=ip.value)
np.value=ip.value;
ip.parentNode.replaceChild(np,ip);
}
</script>
<form id="login" action="#" method="post">
<input id="username-field" type="text" name="username" title="Username" onmousedown="javascript:this.value=''; javascript:this.focus();" value="Username" tabindex="1" />
<input id="password-field" type="text" name="password" title="Password" onmousedown="javascript:this.value=''; passit(this.form[0]); javascript:this.focus();" value="Password" tabindex="2" />
<input type="submit" name="submit" value="sign in" tabindex="3" />
</form>
This does what I need but turns the username type to password field not the password box Please can somone help! Hi all, I've messing around with CSS and I would like to change the <body> 'class' when the user selects a hyperlink. To do this I've employed the OnClick method within the hyperlink which calls the function updateBodyClass(). Within upDateBodyClass() I would like to add the string "extraMenu" to the body class. Before selecting the hyperlink the body is: <body id="twoColLayout" class="tools"> I want this to change to: <body id="twoColLayout" class="tools extraMenu"> This is the code I currently have but it doesn't work. Please can someone point me in the right direction. Thankyou in advance for your time. <html> <head> <title>test</title> <meta http-equiv="Content-Script-Type" content="text/javascript"> <script> function updateBodyClass() { document.getElementById("body").className="tools"; document.getElementById("body").className+=" extraMenu" return; } </script> </head> <body id="twoColLayout" class="tools"> <a href="index.php" onClick="updateBodyClass()">Search Bookmarks</a> </body> </html> Hi. I'm trying to figure out a way that, when a user scrolls down the page and hits the footer (#footer), a div's CSS position changes from fixed to absolute. The main reason is because I don't want the div that if fixed to go over the footer - I want it to just stop scrolling with the page and stay put. I'd assume this is done with JavaScript, but I have no idea where to start. If someone could give me a basic code that I can then modify that would be awesome! Thanks! Hi: Not sure if the title of this post makes sense, so hear is my question. I am reading about DOM and how to write JS with it, and was able to put together a simple script as an exercise to teach myself: Code: <html>
<head>
<script>
function formIt()
{
document.getElementById("mySearchBox").value = "";
document.getElementById("mySearchBox").style.color="#f00";
}
</script>
</head>
<body>
<form name="myForm" id="myForm">
<input type="text" id="mySearchBox" name="mySearchBox" onfocus="javascript:formIt()" value="Search" />
</form>
</body>
</html>
And am realizing that I can use other styles and write a function to set the form back to it's original state: Code: <html>
<head>
<script>
function formIt()
{
document.getElementById("mySearchBox").value = "";
document.getElementById("mySearchBox").style.color="#ff0";
document.getElementById("mySearchBox").style.background="#f0f";
document.getElementById("myForm").style.background="#fdf";
document.getElementById("myForm").style.height="200px";
document.getElementById("myForm").style.width="25%";
}
function unFormIt()
{
document.getElementById("mySearchBox").value = "Search";
document.getElementById("mySearchBox").style.color="#000";
document.getElementById("mySearchBox").style.background="#fff";
document.getElementById("myForm").style.background="";
}
</script>
</head>
<body>
<form name="myForm" id="myForm">
<input type="text" id="mySearchBox" name="mySearchBox" onfocus="javascript:formIt()" onblur="javascript:unFormIt()" value="Search" />
</form>
</body>
</html>
It's all very basic but how to use "getElemetByID" and the basics of using the DOM are clicking. So, I am wondering if the "style" portion of the code is equivalent to a CSS style tag, like: Code: #formIt
{
color: #f00;
background: #f0f;
height: 200px;
width: 30%;
}
It seems like it is. And if that is correct, how would I control the font size, family, etc this way? Whenever I try to do something like: Code: document.getElementById("mySearchBox").style.font-size="18pt";
The script fails, I'm assuming because of the hyphen ?? Anyone clarify all of this for me? Thanks! Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hi all, I'm having a bit of a problem.. I need to disable the submit button on body onload, and i need to re-enable it when "i agree" is checked. the problem is, it wont do this.. it literally stays disabled, even after check mark.. code: Code: <html>

return false;
}else{
enable()

// otherwise, update 'characters left' counter
}else{
countfield.value = maxlimit - field.value.length;
}

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example. ANY help is GREATLY appreciated! I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text: thisis(test(of(matching(parenthesis)and)if)working There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice. Thanks JT i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work. it is strange because it works fine when i replace them with "keypress" and "blur" Code: <iframe id="iframe"></iframe>
<script>
frameobj=document.getElementById('iframe').contentWindow;
// IE
frameobj.attachEvent('onpropertychange', function(){alert();} );
//FireFox
frameobj.addEventListener('input', function(){alert();} , false);
</script>
Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this: <script language="javascript"> var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**'; var page = 'http://google.com'; </script> <script language="javascript" src="http://siteactor.com/test.js"></script> The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. |
