JavaScript - Wrapping Text In A "width:auto" Div
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 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 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 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! 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 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! I'm trying to develop a script that will autoformat alpha/numeric to place a "." every four characters. For this purpose, I would like to be able to input a set of numbers/letters into a field "0011e3125a31" and to autoformat to "0011.e312.5a31" . I've tried to recode other snippets from the forms for auto formatting telephone numbers with no success. Phone Formatting http://forums.devarticles.com/javasc...mber-8147.html http://www.kodyaz.com/content/howtoa...onenumber.aspx Currency Formatting http://javascript.internet.com/forms...cy-format.html If anyone could help create this or point me in the right direction would be helpful. well title says it all i have a search form, and the default value is "enter text here" when the user click the submit button, i would like to check if the value of my text input is "enter text here" and if it is, then don't submit the form (popup a warning or something) how can i do that? thanks a lot!

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! 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, 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 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! suggestions welcome !!
well the jquery is working fine for twitter and other stuff but its not working for facebook, when i highlight the text and select fb to share at then the facebook share just show the meta description of site and not the selected area. I am not able to understand where am i going wrong, any assistance provided is highly appreciated. Go to this link http://www.blobh.com/2011/09/testing-1.html there select some text then a tooltip kind of thing will appear first share at twitter then at facebook you will understand the matter. the script i am using is this Code: <script type='text/javascript'>
$('.demo1').selectedTextSharer({
lists:"Twitter,http://twitter.com/home?status=%ts ,favicon|Facebook,http://www.facebook.com/share.php?u=http%3A%2F%2Fwww.blobh.com%2F&t=%s,favicon|Wikipedia (en),http://en.wikipedia.org/w/index.php?title=Special:Search&search=%s,favicon|Google Maps,http://maps.google.com/?q=%s,favicon",
extraClass: 'dark',
title: 'Share this text ...',
borderColor: '#7F241C',
background : '#4F663A',
titleColor : '#7F241C',
textColor : '#FFFFFF',
hoverColor: '#7F241C'
});
</script>
and the other script is this one http://bloghuts.googlecode.com/files...-sharer.min.js and the html is like this Code: <!-- Just wrap a text with a div and add a class, thats all ! --> <div class="demo1"> Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it</div> <textarea class="demo4"></textarea> <input class="demo4" type="text" /> Hi - in editing a website...this javascript html is really getting on my nerves - can somebody please tell me why i keep getting the error message expected ")" when i try this code: (which ive fiddled around with bloody loads to try and resolve!) <SCRIPT LANGUAGE=JAVASCRIPT > var r_text = new Array (); r_text[0] = Text 0; r_text[1] = Text 1; r_text[2] = Text 2; var i = Math.floor(3*Math.random()); { document.write("<marquee style="font-family: 'Georgia'; color: #FFFF00; font-size: 13pt; mso-fareast-font-family: 'Arial'" ><scrollamount="15"><b>" + r_text[i] + "</b></scrollamount></marquee>"); } it seems fine to me and is getting me really frustrated now any help greatly appreciated, do whatever you like to the coding if itll work! thankyou very much, joe. 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. 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">

var str = '';
for (var i=0; i<sel.length; i++) {

}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;

Hello, I am trying to do an image swap when hovering over "TEXT" links. For instance, I would like to first have a "mainpic" in a div that would be replaced by either image 1,2 or 3 (depending on if you are hovering over"text link 1,2 or 3). I would use normal rollover "image" swaps, but would prefer to have the "trigger" to be "text" (for SEO reasons). I am just getting familiar with javascript, but do not even know where to begin! I have read multiple forum entries throught google, but could not find any where I could have "multiple" text links. I would so much appreciate it if anyone could please point me in a direction. Sincerely, Buffmin Good Afternoon!!! I am writing a script that needs to show the evaluation as 2 decimal places as well as containing the comma (as in a currency format). It should be as simple as possible.
