JavaScript - [need Help] Getting An Element By Class Name?
So, I have this javascript that works just fine... But...
PHP Code: <script language="javascript"> function addBtn() { element = document.createElement("input"); element.setAttribute("type", 'button'); element.setAttribute("value", 'Track'); element.setAttribute("name", 'element'); element.onclick = function() { alert("Tracking"); }; var btn = document.getElementById("gs-track-btn"); btn.appendChild(element); } </script> <div id="gs-track-btn"></div> How would I target that div if the " gs-track-btn " id was a class? Similar TutorialsThe script inside my opening if statement is working, but is the rest of this written right? I'm just want my script to run after it makes sure that a div class named single-journal-entry-wrapper is on the page. Code: function doit() {
document.getElementsByTagName("div")
for ( var x = 0; x < div.length; x++ )
{
var div = div[x];
if ( div.className.indexOf("single-journal-entry-wrapper") >= 0 )
{ do somethang!}
}
}

Hola, I have a problem where I have a number of random set of elements that have a fixed rule for class name. I want to move them to a container element according to this class name. So for example the site generates Code: <p class="dog-1"></p> <p class="dog-2"></p> <p class="cat-1"></p> <p class="dog-3"></p> My output would be ideally Code: <div class="dog"> <p class="dog-1"></p> <p class="dog-2"></p> <p class="dog-3"></p> </div> <div class="cat"> <p class="cat-1"></p> </div> When searching for a solution, all I could find was simple ordering of elements according to class... Thanks 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> The bit of code in bold in the code below is giving me this error in IE: Error: Code: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; Tablet PC 2.0; InfoPath.2; OfficeLiveConnector.1.4; .NET CLR 3.0.30729; OfficeLivePatch.1.3; MSN OptimizedIE8;ENGB) Timestamp: Tue, 16 Mar 2010 15:07:11 UTC Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) Line: 0 Char: 0 Code: 0 URI: http://www.mateinastate.co.uk/users/mateinastate Code: Code: if(document.getElementById('msn1').innerHTML=="")

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! Hello, I am new with Javascript and running into this problem that I don't understand. I define a base class that only contains an array "elements", and a derived class that contains nothing more (for simplicity): Code: function baseClass() {
this.elements = new Array;
}
function derivedClass() {
}
derivedClass.prototype = new baseClass;
Then I create two instances of the derived class, and add two elements in each: Code: a = new derivedClass();
a.elements.push("A");
a.elements.push("B");
b = new derivedClass();
b.elements.push("C");
b.elements.push("D");
When I examine the contents of these arrays, I see that both a.elements and b.elements contain {"A","B","C","D"} ! I.e. as if the two arrays are in fact the same array! But these are two separate instances of the class, I expect two separate arrays. Note that if instead I use the base class: Code: a = new baseClass();
a.elements.push("A");
a.elements.push("B");
b = new baseClass();
b.elements.push("C");
b.elements.push("D");
then I get a.elements = {"A","B"} and b.elements = {"C","D"}, as I would expect. Could someone explain to me the problem with using the derived class? Thank you, Stephanos Hi, (new to javascript) Code: digAudio = document.createElement("audio");
digAudio.setAttribute('src',hypeDocument.documentName()+'_Resources/'+'digging.m4a');
digAudio.id = "diggingAudio";

the audio element is added (I can play the audio) but I can't get it by its id ? thank you I have the following code Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a></td> </div> what i want to do is this: Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a><a href="anotherlink">another_link</a></td> </div> how can i go about achieving this? HI I want to write a search for my site .I make a new panel in the left of my menue and it has a text input and an image which when that user click on it javascript opens a new window which is a php page.The part I don't know how to do is when the user click on the image it should get the content of the text input and pass it to the url.For the hyperlink of the image I use "<a href="javascriptpen_window('includes/func/search.php?id=" But I don't know what should I write after that to get the content of the text input and put it in the next of the id. How can I do so? Thanks Im trying to duplicate an image multiple times here is what I have Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script type="text/javascript">
var totalNumber = 1000;
function insert(num) {
var cont = document.getElementById("cont");
var img = document.createElement("img");
var percent = num/totalNumber;
var result = cont.offsetWidth * percent;
var dup = result/100*2;

Hi I have DropdwonList with elements, 1,2,3 and 4.. and I have another DropdownList with options Normal, Standard, Emegency, and Expendited. Can you help me with a code, so that when I select "1" option on the first dropdown, the "Emegency" option on the second dropdown is set/selected. Thanks in advance Hi all Not sure how to tackle this. I haven't done any DOM manipulation and this is a tag within a tag. Another thing is submit is Ajax and therefore can be hit many times --- so I guess I need to also check if element already exists. The result comes back from PHP and I think wipes out anything in the result area. I want to create this: Code: <span id="loading"><img src="loading.gif" /></span> Code: <div id="results">which should populate here</div>
<script type="text/javascript">
function loading(){
?
</script>
<input type="button" name="submit" id="submit" onclick="loading();"/>
How do I begin this? Help appreciated. LT oh this is my Ajax just in case what i'm trying to do should be done from here. Code: <script type="text/javascript">
$(document).ready(function() {
$('#submit').click(function(){
//Get the values
var amount = $('#amount').val();
var from = $('#from').val();
var to = $('#to').val();
var params = "amount=" + amount + "&from=" + from + "&to=" + to;
$.ajax({
type: "POST",
url: "change.php",
data: params,
success: function(data){
$('#results').html(data).fadeIn("slow");
}
});
});
});
</script>
Ok, Simpler question. I'm trying to get the text in an xml element. Instead of getting just the text in the first child element I'm getting the text of all the children elements. How can I get it from just the first? Code: var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
function xmlload(filexml)
{
xmlDoc.async="false";
xmlDoc.load(filexml);
xmlObj=xmlDoc.documentElement;
}
xmlload('urlhere');
document.getElementById("nmbr").value=myVar;
myVar = xmlObj.childNodes(0).childNodes(19).firstChild.text;
document.getElementById("comment_t").innerText= myVar;
Hello I am fairly new to Javascript and found this code online but can't seem to get it to work right. here is the code I am using it is suppose to apply a style attribute the the id "toplink" but I can't seem to get it to work right. Code: $(document).ready(function(){
menuYloc = parseInt($(name).css("top").substring(0,$(name).css("top").indexOf("px")))
$(window).scroll(function () {
var offset = menuYloc+$(document).scrollTop()+"px";
$("#toplink").animate({top:offset},{duration:500,queue:false});
});
});
Thanks in advance Hi, Would someone here please help me with this script. I know I am a complete hack at this, but I need to get it to work. Your help is appreciated. As you can see, based on the if statement, I need to leave the Div element below hidden, or un-hide it. I know the first part works. The second part (after "else" ) is where I am having the problem. Code: <td>
<script type="text/javascript">
if ([fieldXX]==1)
{
document.write("<a href='page1.asp?itemid=1234'><img src='images/btn-choose.gif' border='0' alt='choose button'</a>");
}
else
{
var id = 'hide-buy-btn';
var item = document.getElementById(id);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}
</script>
<div id="hide-buy-btn" class="hidden">
x
xother button code
x
</div>
</td>
Alright, this is going to sound strange, but bear with me here... Code: <input type="text" name="_F0827U" size="015" maxlength="015"> <input type="submit" class="cmdkey" name="_K040827" value="..."> Say I have multiple isntances that look similar to the above. However, I have no possible way of identifying them uniquely (because I don't know the name prior to generation). Is it posable, using JS, to snag the previous element and strip it of it's tags then rewrite a new element isntead of the two originals, say using an onClick() event on either of the elements? Hi all i have the following code. Code: $(document).ready(function(){
$("ul, li, a, p, img").hover(
function(){
var origBorder = $(this).css("border");
var elementID = $(this).attr("id");
$(this).css("possition", "absolute").css("z-index", "100").css("border", "1px solid red");
},
function(){
$(this).css("border", "none").css("z-index", "1");
}
);
});
it is suposed to outline the element that i am hovering over. Yet if I hover over say an <li> it will outline the li and the ul. Any ideas on how to just outline the element im hovering over? Hello. I am setting up a simple registration page for a community arts project, but I am new to JS and having some issues. Right now I have a list of check boxes like this: Code: <input type="checkbox" id="HA0001" onclick="updateTotal()" /> Wendy Day <input type="checkbox" id="HA0002" onclick="updateTotal()" /> Al Benne <input type="checkbox" id="HA0003" onclick="updateTotal()" /> Julie Steppe What I would like to do is GET the input boxes ID value - which will be different for every checkbox. That value will correspond with a variable of the same name in my javascript code, that will be added or subtracted from the users total cost. So when a box is clicked, I need my variable (called "currentId") to update to the ID value, such as "HA0001" - etc. I was thinking something along the lines of this, but I know it is incorrect: Code: var currentId = document.getElementById.id; All the other add/subtract stuff I will figure out, but I am having a problem getting the ID value from a checkbox when it is clicked. Can anyone help me figure this out? THANKS! -AJ I'm trying to add an input element to all forms using appendChild. The script first searches for input elements with the name of "myinput". If it finds an input element with that name, it assigns the value "myvalue". If it can't find an input element with that name, it tries to create a new one for all forms. Code:
if (document.getElementsByName('myinput')) {
var testcode = document.getElementsByName('myinput');
for (var i=0; i < testcode.length; i++){
testcode[i].value = "myvalue";}
}
else {
var z = document.createElement("input");
z.type = "hidden";
z.name = "myinput";
z.value = "myvalue";
z.id = "mycode";
var d = document.getElementsByTagName('form');
for (var i=0; i < d.length; i++){
d.appendChild(z);}
}
What's wrong with my code? Thanks! I am trying to have it so that when someone choose a value from the select box, it then displays it in the html. The problem is im not very good with javascript, and my error keeps coming up as undefined where as before it was coming up as "[object HTMLSelectElement]". Can anyone tell me whats up? PHP Code: <html> <head> <script type="text/javascript"> function moveValue() { var no=document.getElementById("no"); var option=no.options[no.selectedIndex].numberr; document.getElementById('numberr').innerHTML = option; } </script> </head> <body> <form> Select numbers:<br /> <select id="no"> <option>0</option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> </select> <input type="button" onclick="moveValue()" value="-->"> <i id="numberr">Testing</i> </form> </body> </html> and now that i look at it, i suspect that the reason that it is not working is that i should have "ID"'s or value's on each of the options but i do not know for certain |
