JavaScript - Need To Know How To Include Css Class Change In Function
I have some javascript code that hides and unhides a menu when a link is clicked, and that is working just fine. What I also need the function to do is switch the CSS class of change_this in the code below to change_that when the link is clicked, and then switch it back to change_this when the link is clicked again. Can someone assist me? I have tried integrating/modifying other scripts I found with this one, but nothing has worked for me. It seems so simple, but I just cant get this thing working. Thanks to anyone who replies with help!
Code: <script type="text/javascript">
function HideandUNhideObj(ThisObj){
nav=document.getElementById(ThisObj).style
if(nav.display=="none"){
nav.display='block';
}else{
nav.display='none';
}
}
</script>
Code: <li class="change_this"><a id="nav" href="javascript: void();" onclick="HideandUNhideObj('display');"></a>
<ul id="display" style="display: none;">
<div id="container_div">stuff</div>
Similar TutorialsI was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on: Code: function handleFileSelect(e){
var files = e.target.files;
var output = [];
for(var i=0,f;f=files[i];i++){
if(f.type.match('image.*')){
var reader = new FileReader();
reader.onload = (function(theFile){
return function(e){
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
document.getElementById('list').insertBefore(span,null);
};
})(f);
reader.readAsDataURL(f);
}
}
document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
}
document.getElementById('files').addEventListener('change',handleFileSelect,false);
To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is: Code: class.event = (function(arguments){
//stuff you put in a function...
})(more Arguments?);
I tried to customize a simple one to learn for myself and I wrote this: Code: var a = 'A';
var b = 'B';
test = (function(t){
alert(t);
alert(b);
})(b);
test(a);
The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused. The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works. Hi! I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe. Link to the page: Franklin Township Soccer Club - Change Field Status My sad, sorry attempt =| Code: $( "li.open" ).click(function() {
$( this ).toggleClass( "closed" );
});
$( "li.closed" ).click(function() {
$( this ).toggleClass( "open" );
});
The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so! In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission! I do appreciate any help given! Dave Hi, I need to change my class, but this isn't doing it for me and I don't see why. No error messages, but nothing happens. Code: .myClass {
background-color: yellow;
}
document.getElementById("myId").setAttribute("class","myClass");
Thank You in Advance for Your Help, Lou I have a list like this:
Code: <tr>
<td>Some Text One</td>
</tr>
<tr>
<td>Some Text One</td>
</tr>

When I click a radio button, I want the text to "dim", that is, change color. So I have two CSS classes, on and off. Here's the JS PHP Code: function enableCFFID() { document.cartform.cffid.disabled=false; document.getElementsName('cffidtext').class="cffidon"; } function disableCFFID() { document.cartform.cffid.disabled=true; document.getElementsByName('cffidtext').class="cffidoff"; } But, this does not work. What am I doing wrong??? Hello, Let's say I have a <div class="main1 secondary">. Is there an easy way to change "main1" to "main2" and make sure it is the first class? I was thinking about using jquery with .removeClass and .addClass but addClass adds it to the end. Any help would be great! Thanks hi all, I am using ajaxcontent javascript to load content into certain parts of the website and all my links work that way.. the problem with that is that I can't use classical approach for building menus.. like when you assign "current " class to your link and then it changes color or whatever when you follow link to another html or whichever website. So I have menu like this .. Code: <li class="current"><a href="index.htm"><b>One</b></a></li>
<li><a href="javascript:ajaxpage('2.php', 'right');"><b>Two</b></a></li>
<li><a href="javascript:ajaxpage('3.php', 'right');"><b>Three</b></a></li>
<li><a href="javascript:ajaxpage('4.php', 'right');"><b>Four</b></a></li>
<li><a href="javascript:ajaxpage('5.php', 'right');"><b>Five</b></a></li>
I'm sorry for my English is so bad.. but I will try to explain what I'd like to achieve.. I'd like to put in some kind of onclick script which will change class of that <li> to current but at the same time I want to change <li class="current"> to <li class=""> or <li class="whatever">... so here I go again.. Code: <li class="current"><a href="index.htm"><b>One</b></a></li>
<li><a href="javascript:ajaxpage('2.php', 'right');"><b>Two</b></a></li>
<li><a href="javascript:ajaxpage('3.php', 'right');"><b>Three</b></a></li>
<li><a href="javascript:ajaxpage('4.php', 'right');"><b>Four</b></a></li>
<li><a href="javascript:ajaxpage('5.php', 'right');" onclick="this.className='current'"><b>Five</b></a></li>
Now this changes the <li> class to current and I only want to have 1 current. In this case link "Five" should have current class others should have no class or class="whatever" its same Thank you for any answers in advance Hey, I currently have my menu on a web page set out using the following method: Code: <div class="linkbox" onmouseover="this.className='linkbox2'" onmouseout="this.className='linkbox'" onclick="location.href='http://www.upthegame.net/';"> General Chat </div> I was wondering if there was a way using javascript to set ALL <div>'s with the class name "linkbox" to change to the class name "linkbox2" onmouseover and return to "linkbox" onmouseout. I would like this to be in a seperate file, I'm guessing this would probably be within an onload function or something along those lines. I'm only familiar with basic JS so please go easy on me Any help is much appreciated. Thanks, Tom. Hi, is it possible to change the class of an element onClick with a fade? This is the code I have so far which works great for changing the class but I have no idea how to include a fade in this. I am changing the class in order to change the background-image of a div. Code: <a href="#none" onclick="document.getElementById('tool').className ='tool1'">
Many thanks, M thanks anyway
So if both validations work seperatley (if I just put radio buttons validation in the function without the spinner validation then radio buttons validation works and same vise versa), how come when I put both validations in the function, the top validation which is the radio validation works but the bottom validation which is the spinner validation does not display a message when it is suppose to? Code is below: Code: <head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>Create a Session</title>
<script type="text/javascript">
function validation() {
var errMsgO = document.getElementById("radioAlert");
var btnRadioO = document.getElementsByName("sessionNo");
var isbtnRadioChecked = false;
var errQuesMsgO = document.getElementById("numberAlert");
var questionNumberO = document.getElementsByName("txtQuestion");
for(i=0; i < btnRadioO.length; i++){
if(btnRadioO[i].checked){
isbtnRadioChecked = true;
}
}
if(!isbtnRadioChecked) {
errMsgO.innerHTML = "Please Select the Number of Sessions you Require";
} else {
errMsgO.innerHTML = "";
}
return false;
if(questionNumberO[0].value == 0){
errQuesMsgO.innerHTML = "Please Set the Number of Questions";
} else {
errQuesMsgO.innerHTML = "";
}
return false;
}
</script>

I'm using javascript to change the color of certain words in an html document. Right now it uses <font> to make the change. I would like to use a CSS class named "alert" from an external style sheet to make the change. I've tried multiple things but no luck (className="alert", setClassName="alert" ) What is the correct way to replace the font part with a CSS class? Here is the working script: Code: <script type = "text/javascript">
window.onload = function (){
var text = document.getElementsByTagName('body')[0].innerHTML;
text = text.replace(/disabled/gi, "<font color=red>Disabled</font>" );
text = text.replace(/\blocked/gi, "<font color=red>Locked</font>" );
document.getElementsByTagName('body')[0].innerHTML = text;
}
</script>
Hey all, Hoping someone could help me out with some javascript coding as I am a complete novice to this! I am currently building a website using 1 static page and all the content will be pulled in through different iframes by clicking on a navigation on the page. I found a very handy piece of javascript coding that lets me remove a class from one link and move it to the link that was clicked on (the code will be below). The issue I am facing with this is that if I have Home set to class="On" to begin with and then click on Location, the background image will be added to the Location section but won't get removed from Home until it is physically clicked on. Can anyone help me out with how I can get this to work correctly? javascript: Code: <script language="JavaScript" type="text/javascript">
var Lst;
function CngClass(obj){
if (typeof(obj)=='string') obj=document.getElementById(obj);
if (Lst) Lst.className='';
obj.className='On';
Lst=obj;
}
</script>
HTML: Code: <div id="navWrapper">
<div id="globalNav">
<ul>
<li onclick="CngClass(this);" class="On"><a href="iframes/home.html" target="content_iframe">Home</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/location.html" target="content_iframe">Location</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/speakers.html" target="content_iframe">Speakers</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/agenda.html" target="content_iframe">Agenda</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/useful_material.html" target="content_iframe">Useful Material</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/event_presentations.html" target="content_iframe">Event Presentations</a></li>
<li onclick="CngClass(this);" class=""><a href="iframes/gallery.html" target="content_iframe">Gallery</a></li>
</ul>
</div>
<div id="localNav"></div>

i have an image with an onclick function and parameters 0,1 i want to change the parameters of the onclick function through the same function? Code: <img id="down0" onclick=swap(0,1) />
<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}
</javascript>
normally it should change the onclick to swap(1,2) but it remains 0,1 whats happening?? p.s. plz dont tell me about the javascript tag, its just for quick explaining... Hey All - I asked this a few days ago.. what I came up with works just fine, but I feel it doesn't take advantage of "classes". If you think I could make this better by turning it into a class or using some other notation, that would be great. Keep in mind, ALL this does is rewrite a pagination.... for a search return in a lightbox. I have this function called in the return function... Code:
var srcpagParams = $H();
function buildPagi(param, currdsplyNum){
var temDsply = new Template('<strong>[#{total_display}<span id="count">#{prevImg} #{links} #{nextImg}</span>'),
crnt_link = srcpagParams.set('crnt_link', param), // the page we want to see
dsplyNum = srcpagParams.get('paginateNum'), // what is the number of returns per page
ttl_lnks = Math.ceil( srcpagParams.get('numFound') / srcpagParams.get('paginateNum')), // total pages
data_template = new Hash();
data_template.set('total_display',srcpagParams.get('numFound'));
bldImg = function() {
var prvB = '<a href="#content" id="pagiPrev" onclick="firesrc(this)">Prev<img src="blank.gif" /></a>';
var nxtB = '<a href="#content" id="pagiNext" onclick="firesrc(this)">Next<img src="blank.gif" /></a>';
data_template.set('prvImg',(crnt_link > 1) ? prvB : "");
data_template.set('nxtImg',(crnt_link < ttl_lnks) ? nxtB : "");
}
bldLk = function(){
var holder = "";
if(ttl_lnks > 1){
var linkStr = new Template(' <a href="#content" onclick="firesrc(#{pos});"> Go to page #{pos}</a> ');
$R(1,ttl_lnks).each(function(n) {
var posit = {pos : n}
holder += (crnt_link == n) ? " " + n + " " : linkStr.evaluate(posit);
});
data_template.set('links',linkholder);
}
}
bldRng = function(){
var currPaneRg = (dsplyNum * crnt_link) - (dsplyNum - currdsplyNum);
data_template.set('range',((crnt_link - 1) * (dsplyNum) + 1 ) + " - " + currPaneRg);
$('pages').update(temDsply.evaluate(data_template)).show();
}
firesrc = function(cl){
var pagiPane = (typeof cl === "number") ? cl : (cl.id == "pagiNext") ? crnt_link + 1 : crnt_link - 1;
var start = crnt_link * srcpagParams.get('paginateNum');
Alertsrc( $F('query') ,(pagiPane)) // pass the query to the json to return the current search request
}
bldImg();
buildLnk();
bldRng();
};
Since some of the data declared at the top changes depending on the return, I didn't know if I could "initialize" it in a class.
But could I turn this into a class and if so - what I just use:
var buildPagi = create.Class({
initialize: object.extend({
})
})
Call the function when we are passed some data: Code: buildPagi(somevalue, somevalue2) ** NOTE: I use the libraries prototype and jquery.. so use Create.Class and new Template are within the libraries... etc.. so, is there a more eloquent, or robust way to write what I did above? I have a question: look at the following html code: /****html***/ <div class='class1'>text1</div> <div class='class1'>text2</div> <div class='class1'>text3</div> ...... /**html***/ If I want to change the background color of the textn by clicking it, what should I do instead of inserting "onclick='someFunction()'" in every div? Ok...so here is what I have: Code: function myClass() {
this.checkLogin = function(name,pwd) {
if(name.length > 0 && pwd.length > 0) {
$.ajax({async: false,
type: "post",
url: "url",
dataType: "json",
data: "data",
success: this.parseData});
}
}
this.parseData = function(data) {
this.status = data.status;
alert(this.status);
}
this.getStatus = function() {
alert(this.status);
}
}
Everything works above. The first alert shows that this.status was set to 'error'. However, if I call myClass.getStatus(), I get undefined. How can I get the parseData function to set the variables in the parent function? Thanks! First of all, I must say that I am recently introduced to JavaScript and I am not fully aware of its complete functionality. So I have an HTML document which has defined within a its body a JavaScript function and I have also a JApplet class which is also loaded in the HTML and can call the JavaScript function. But I have also another Java class which is not an applet and I would like to find a way for this class to be able to call the JavaScript function (but it is essential for this class not to be an applet). I am aware that this would raise some security concerns but it is for local usage and I am interested to hear some ways if possible for this to be done. Thank You beforehand to all of you! I got 3 sections on the site, at the bottom of each are 5 bars which are used to change the text color. I'm trying to minimize the code, so I created an array which contains all the colors, but I'm not sure where to put the call to the array. If I put it in the for loop, the selected color will always be green no matter which color you click. The bars should also go up to 40px when clicked and when the next bar is clicked the current bar at 40px should go back to it's originals size(20px) Any ideas? this is the JS Code: var colors = new Array(4);
colors[0] = "#ed1c24";
colors[1] = "#736257";
colors[2] = "#620460";
colors[3] = "#e87e01";
colors[4] = "#00a650";
function changeColor(numerSekcji, numerKoloru)
{
document.getElementById('section' + numerSekcji + 'Color' + numerKoloru).style.paddingTop = 20 + "px";
document.getElementById('section' + numerSekcji + 'Color' + numerKoloru).style.marginTop = 0 + "px";
for (i = numerKoloru; i <= 4; i++) {
document.getElementById('section' + numerSekcji + 'Color' + numerKoloru).style.padding = 0 + "px";
document.getElementById('section' + numerSekcji + 'Color' + numerKoloru).style.marginTop = 20 + "px";
document.getElementById('section' + numerSekcji + 'Text').style.color = colors[i];
}
}
}
this is the html for the color boxes Code: <a class="color1" id="section1Color1" href="javascript:changeColor(1, 1)"> </a>
<a class="color2" id="section1Color2" href="javascript:changeColor(1, 2)"> </a>
<a class="color3" id="section1Color3" href="javascript:changeColor(1, 3)"> </a>
<a class="color4" id="section1Color4" href="javascript:changeColor(1, 4)"> </a>
<a class="color5" id="section1Color5" href="javascript:changeColor(1, 5)"> </a>
edit: edited the js... edit2: all the colors are going through the loop, the 1st one is missed :S changing the html to start with ...changeColor(1, 0) does not help. Clicking on the 1st bar doesn't run the loop. I have the one javascripts button code and the functions is on "text area" .. but how do I change the function of this button to go to google.com website ..? how to make it.. the javascripts button code : Code: <input type="image" src="tesdt-copy-1.gif"
onmouseover="this.src='file:///C:/Documents%20and%20Settings/Administrator/Desktop/test/main%20test%20scripts/test2-copy-2.gif';"
onmouseout="this.src='file:///C:/Documents%20and%20Settings/Administrator/Desktop/test/main%20test%20scripts/test2-copy-1.gif';"
onclick="CB(document.getElementById('output').value); return false;"
</form name="I5" width="38" height="38">
