JavaScript - Getelementsbyclassname - For Multiple Classes (e.g Class="foo Bar")
hi all,
im on a really tight deadline with this and have been strugglign all day. (i know nothing about JS!) here's my code: Code: <script language="Javascript"> var allHTMLTags = new Array(); function fadeIn(SRC) { var allHTMLTags=document.getElementsByTagName("*"); for (i=0; i<allHTMLTags.length; i++) { if (allHTMLTags[i].className.indexOf(",") !== -1) { allHTMLTags[i].style.opacity='1'; } } } function fadeOut(SRC) { var allHTMLTags=document.getElementsByTagName("*"); for (i=0; i<allHTMLTags.length; i++) { if (allHTMLTags[i].className.indexOf(",") !== -1) { allHTMLTags[i].style.opacity='0.5'; } } } </script> <li onMouseover="fadeIn(foo)" onmouseout="fadeOut(foo)"> <div class="foo" style="opacity: 0.5;"> test 1 </div> <div class="foo bar" style="opacity: 0.5;"> test 2 </div> The idea of the above, is that when you hover over the <li> all of the divs with a class CONTAINING "foo" are given an opacity of 1. the problem is, the above script only seems to work with numbers?! E.G - class="1 2" works fine. problem is i need to use words not numbers for the classes. clearly my code is rubbish, i've bodged it together from bits and pieces of different forums. PLEASE can somebody help? the end result needs to go through and find all divs with a class CONTAINING the term specified in the <li> then give them an opacity of 1, then on mouseOut return the opacity to 0.5 im sure this is newb stuff, but thanks in advance for any help you can give! Similar TutorialsHey guys, This is my first time ever posting in a programming forum so please be nice! :) I'll admit right away that this is for a homework assignment, but I really did try to solve it myself before I decided to post here. The instructions are to have a confirm box pop up when links with the HTML class value "external" are clicked. If the user clicks "OK" they should be directed to the linked page. If they click "Cancel" they should not be directed anywhere. Here's my code: Code: function checkClass() { var links = document.getElementsByTagName("a"); for ( var i = 0 ; i < links.length ; i++ ) { var link = links[i]; if (link.className == "external") { link.onclick = clickHandler(); } } } window.onload = checkClass; function clickHandler() { if (confirm("You clicked an external link. Do you really want to leave this site?")) { return true; } return false; } The problem is that the confirm box is triggered on page load and not on link click. I know I wrote Code: window.onload = checkClass; but how else should I call the function? I thought Code: if (link.className == "external") would keep it from going as far as to the confirm box until an external link was clicked. Thanks for pointing me in the right direction, Johanna 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> I found this code sample that when a user clicks somewhere on the image, then an "X" will appear. I would like to have the "X"s remain visible even when the user clicks on a different area of the image. As you can imagine, a user clicks clicks clicks then there are "X"s everywhere. How do I do this? Do I need to create more "div" tags with the mouse click locations? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Mouse position</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta http-equiv="Content-Style-Type" content="text/css"> <meta http-equiv="Content-Script-Type" content="text/javascript"> <script language="JavaScript" type="text/JavaScript"> var posx; var posy; function getMouse(e){ posx=0;posy=0; var ev=(!e)?window.event:e;//IE:Moz if (ev.pageX){//Moz posx=ev.pageX+window.pageXOffset; posy=ev.pageY+window.pageYOffset; } else if(ev.clientX){//IE posx=ev.clientX+document.body.scrollLeft; posy=ev.clientY+document.body.scrollTop; } else{return false}//old browsers } function showP(){ document.getElementById("div2").style.visibility="visible"; document.getElementById("div2").style.top =(posy-10)+'px'; document.getElementById("div2").style.left=(posx-6)+'px'; } </script> <style type="text/css"> .div1 {position:absolute;top:100px;left:100px;visibility:visible;z-index:5} .div2 {position:absolute;top:0px;left:0px;visibility:hidden;z-index:1;color:black;} .div3 {position:absolute;visibility:hidden;z-index:10;font-family:monospace;font-size:20px;font-weight:900;color:black;} </style> </head> <body onmousemove="getMouse(event)"> <div id="div1" class="div1"> <img src="./yourImage.jpg" onclick="showP()"> </div> <div id="div2" class="div3"> X </div> </body> </html> This script works great for populating predefined lists of data into a textarea as selected by the user using a radio button: Code: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Populate Textarea Based on Radio Button Selection</title> <script> text = new Array() text[0] = Array('Hotel', 'Motel'); text[1] = Array('Couch', 'Bed', 'Chair'); function populate(r,f){ t=-1; for(var i=0;i<f.elements[r].length;i++){ if (f.elements[r][i].checked){ var t=i; } } if(t>-1){ f.thefirsttextarea.value= text[t].toString().replace(/,/gi,"\n"); } } </script> </head> <body> <form name="frm"> <input type="radio" name="test" value="0" onClick="populate(this.name,this.form)"> <input type="radio" name="test" value="1" onClick="populate(this.name,this.form)"> <textarea name="thefirsttextarea"></textarea> <input type="submit" value="submit" /> </form> </body> </html> However, I've coded all night only to come across an issue.

Greetings! Let me start by first stating that I've never really coded Javascript before in my life. Having said that, I'm not an idiot and I can generally pick up on things relatively quickly . So, now to the point. I'm currently creating a site in which I've incorporated Protoswitcher (http://cssrevolt.com/upload/files/pr...her/index.html). From what I can tell, it's a relatively simple script. Now the catch is that I wanted to have more than one switcher on my site. And this is where I get stuck. What I did initially was to basically copy the JS file (protoswitcher.js) and rename it something else (userbar.js, for example). I then changed the various places in the script which were previously for "var ProtoSwitcher" to "var UserBar", etc. I managed to get it all to work fine. Both the boxes show up, and they both work as they should (clicking on them changes select bits of CSS). Now the problem I'm having is that the original protoswitcher uses cookies to remember a persons preferences. I cannot for the life of me figure out how to get the "new" protoswitcher (userbar.js) to work with cookies as well. Any help would be much appreciated, and I'm sure I can give you a few dollars for your time . Please let me know if I haven't made sense. TLDL: I want to be able to use several protoswitchers with working cookies. I don't know how. 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! 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 Hello, I'm using "Cut & Paste Multiple Dynamic Combo Boxes" script.

Hello, 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 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 was just wondering if there is an alternative to getAttribute("class") that works in IE8 and its proceeding versions. The code below checks to see if the current tab/div has the hideDiv class, if it doesn't then it finds the position and dimensions of this and adds them to variables. Pre IE9 sets all the values as it should on the first pass but then when it goes through a second and third time to check the other tabs the values are set to zero as the divs have the display:none property in the CSS. Code: if(tabs[l].getAttribute("class") != "hideDiv"){ findPos(tabs[l]); tabWidth = tabs[l].offsetWidth; tabHeight = tabs[l].offsetHeight; } If you would like to see the full code my development area is dev.creativepanda.co.uk - the function called to start it all off is tabChange code for this is at dev.creativepanda.co.uk/js/tabber.js Thanks for any help that you can give. Hello, I am using this code Code: <form style="display: none;" name="num1form" id="num1form" action=""> <input type="image" name="1" id="num1" value="1" src="imgl/img_first_01.png" onclick="document.forms[0].action='javascript:ChangeNum1();'"/> </form> What the above code does is change the action state, it allows me to have multiple image inputs which is great as I can define various inputs with different IDs. However, this is used for one section of the page I happen to have another <form> with basically the same code but it's using num2 values, I'm not sure why but I can only using one of these Code: onclick="document.forms[0].action='javascript:ChangeNum1();'" at a time, for one form only. Is there anyone able to help me divide this, or make these onClick actions unique so they can be used in more than 1 form? Thanks, Keenan 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. 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> 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 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"> <!--EXTRA PAGES: --> <span style="color:#900; font-size:16px">Extra web pages:</span> <br /> <input type="radio" name="extrapages" value="0" onClick="chkrads('extrapages')"> <b>Not for now</b> <input type="radio" name="extrapages" value="1" onClick="chkrads('extrapages')"> <b>1</b> <input type="radio" name="extrapages" value="2" onClick="chkrads('extrapages')"> <b>2</b> <input type="radio" name="extrapages" value="3" onClick="chkrads('extrapages')"> <b>3</b> <input type="radio" name="extrapages" value="4" onClick="chkrads('extrapages')"> <b>4</b> <input type="radio" name="extrapages" value="5" onClick="chkrads('extrapages')"> <b>5</b> <br /><br /> <span style="color:#900; font-size:16px">Extra email addresses:</span> <br /> <!-- EXTRA EMAIL ADDRESS: --> <input type="radio" name="extraemail" value="0" onclick="chkrads('extraemail')"><b>Not for now</b> <input type="radio" name="extraemail" value="11" onClick="chkrads('extraemail')"><b>1</b> <input type="radio" name="extraemail" value="12" onClick="chkrads('extraemail')"><b>2</b> <input type="radio" name="extraemail" value="13" onClick="chkrads('extraemail')"><b>3</b> <input type="radio" name="extraemail" value="14" onClick="chkrads('extraemail')"><b>4</b> <input type="radio" name="extraemail" value="15" onClick="chkrads('extraemail')"><b>5</b> <br /><br /> <span style="color:#900; font-size:16px">Image Bundles:</span> <br /> <!--Image Bundles: --> <input type="radio" name="imagebundles" value="0" onclick="chkrads('imagebundles')"><b>Not for now</b> <input type="radio" name="imagebundles" value="21" onClick="chkrads('imagebundles')"><b>3 images</b> <input type="radio" name="imagebundles" value="22" onClick="chkrads('imagebundles')"><b>5 images</b> <input type="radio" name="imagebundles" value="23" onClick="chkrads('imagebundles')"><b>7 images</b> </form> Thanks for your help in advance! . SOURCE: Here Code: 1 document.onmousemove = mouseMove; 2 3 function mouseMove(ev){ 4 ev = ev || window.event; 5 var mousePos = mouseCoords(ev); 6 } 7 8 function mouseCoords(ev){ 9 if(ev.pageX || ev.pageY){ 10 return {x:ev.pageX, y:ev.pageY}; 11 } 12 return { 13 x:ev.clientX + document.body.scrollLeft - document.body.clientLeft, 14 y:ev.clientY + document.body.scrollTop - document.body.clientTop 15 }; 16 } #1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here? #3: How can "mouseMove" be declared as a function afterwards? #3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work? .

It works great. When I add this: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> It doesn't work. I need it for some aspects of my CSS to work. The code that works without that is: Code: <html> <script> function resizeAll( ) { var divs = document.getElementsByTagName("div"); for ( var d = 0; d < divs.length; ++d ) { var div = divs[d]; if ( div.className == "fn-area" ) { divid = divs[d].getAttribute("id"); imgid = "Img" + divid; var Div1Width, Div1Height; Div1Width = document.getElementById(divid).offsetWidth; Div1Height = document.getElementById(divid).offsetHeight; document.getElementById(imgid).style.width = Div1Width; document.getElementById(imgid).style.height = Div1Height; } } } </script> <head> </head> <body onLoad="resizeAll()"> <div id="Div1" class="fn-area" style="width:100px;height:100px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv1').style.display='block';" onmouseout="document.getElementById('ImgDiv1').style.display='none';"> <img id="ImgDiv1" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/> </div> <div id="Div2" class="fn-area" style="width:300px;height:300px; border:1px solid black;" onmouseover="document.getElementById('ImgDiv2').style.display='block';" onmouseout="document.getElementById('ImgDiv2').style.display='none';"> <img id="ImgDiv2" src="fnclientlib/styles/artwork/creep_stamp5.gif" style="display:none"/> </div> </body </html> |
