I need to get the element by class of "balls" from the div gameContent.
Basically grabbing the lottery numbers from Play4 from this site:
http://www.flalottery.com/play4.do
How can I get the element by class from another class? If I just do balls, all of the numbers show up, which aren't relevant and would mess up data.
Do you mean something like this:
document.getElementsByClassName('gameContent')[0].getElementsByClassName('balls')
Get elements by class "gameContent" followed by "balls". Query assumes that the first gameContent is what we are interested in.
Hope this helps.
you can use the following query selector
var elems = document.querySelectorAll(".gameContent .balls")
That is pure JavaScript. You can of course use the same query selector for jQuery
For instance with jQuery this would be
var elems = $(".gameContent .balls")
Notice how the query selector is identical.
Did you try
$(".gameContent .balls")
Judgeing by the page you've included in your question, you'll probably want to iterate through the <span> elements to get each ball number:
$('.gameContent .balls').each(function(){
alert('next ball: '+$(this).html())
});

I am trying to find the appropriate way to edit an element but it seems like their is only one node with an ID. I have thought of
my code looks like:
var root=document.getElementById("app-mount").childNodes;;
var child = root[n].innerHTML;
But this is not reusable to get the path to any element such as $0 used in chrome dev tools. I was wondering if there was a method one could call on $0 to just give me the path so one could know how to target it as one does for an ID document.getElementById('id');
Edit:
after getting help I have updated my code to look like:
document.querySelectorAll('svg')[1].outerHTML="<img id='orb' class='orb' src='https://i.imgur.com/k3d8qMN.gif' width='50' height='60'>"
Its for a theme I am making for discord!
Thanks for the help!
I am not sure that I am following your question very well, but if I understand you correctly, you are looking for something like querySelector or querySelectorAll.
You can use CSS commands to target various HTML elements. eg:
document.querySelector('div'); //returns the first div
document.body.querySelectorAll('div'); //returns all the divs attached to the body element
You can also target ids:
document.querySelector('#app-mount');
or classes:
document.querySelector('.blue');
and query selectors may also be used:
document.querySelector('#app-mount > ul > li:nth-child(3)');

I have added a new element dynamically through jQuery like this:
var elem = $('#unique').append($('<span>').attr('data-rollNo', i));
Now I need to use this element after this to add something to it. Is there a way I can store a reference to this element here, so I done need to search the entire DOM every time I edit this?
Use appendTo method instead of append:
var $span = $('<span>').attr('data-rollNo', i).appendTo('#unique');
Now, span is appended and you also have a reference to this new object.

friends
I'm writing an app. I'm creating some list items using JavaScript. Each of those items has an id, that is the code of that element in my database.
I need to take that id value to make some searches in my database. So, how can i do that?
Using jQuery:
$('.my-ul-class-name li').click(function() {
alert($(this).attr('id'));
});
<ul class="my-ul-class-name">
<li id="myId1"></li>
</ul>
This code is saying "Whenever you click on any LI item in the list with classname "my-ul-class-name", ALERT me the ID of the LI item.
here's the way to select the id :
document.getElementById("idname");
You can add another attribute after it.

Ok guys, let's suppose I have one html form with 2 fields like this:
<fieldset>
<p><label>Login<br><input type="text" class="inpText" name="user" id="user"/> </label><span class="provider">#isp.com</span></p>
<p><label>Password<br><input type="password" class="inpText inpPass" name="pass" id="pass"/></label></p>
</fieldset>
Now, I need to replace the entire code inside the < fieldset > - < /fieldset>.
Remove both inputs, or add how many inputs I need, or just write one < p > inside the < fieldset>, or whatever, I just need to replace the code between 2 'flags'; in this case the fieldset. How to do that using javascript? JQuery is acceptable too, but I prefer javascript only if possible.
Thank you.
give the fieldset an id and do $('#fieldset_id').html('html to replace with');, or with plain js use document.getElementById('fieldset_id').innerHTML = 'html to replace with';
Well if jQuery is acceptable:
$("fieldset").html("NEW HTML HERE");
Give your fieldset an id and then use document.getElementById("fieldSetId") to get the fieldset. You can then alter it with innerHTML property.
Here is a demo http://jsfiddle.net/thefourtheye/vF7Xb/

Suppose the following markup:
<body>
link [ some text here
link [ some more text here
</body>
Is there anyway to use jQuery to remove the ' [ ' from the top line but not the bottom one?
Note: I don't have the access to the markup, but I can add elements, divs etc. using jQuery if I wanted to. BUT jQuery does not need to target the string of ' ] ' in particular - it can be something like "remove next 3 characters after uniqueLink1.
jQuery doesn't really help much with manipulating text nodes, but here it is:
var tn = $('a[name="uniqueLink1"]')[0].nextSibling;
tn.nodeValue = tn.nodeValue.replace('[', '');
Demo
$()[n] is a shorthand for $().get(n), so [0] will return a reference to the first matched DOM element inside the jQuery object, the uniqueLink1 anchor.
nextSibling, as the name implies, grabs the next sibling node. In this case, the text node that follows the given anchor element.
nodeValue gets and sets the content of the text node.
String.replace() given a string as the first argument replaces only the first occurrence, thus this should be enough enough given the DOM structure is similar to the posted one.
This will filter the textnodes, and remove a [ from the first on it finds:
var textNode = $('body').contents().filter(function() {
return this.nodeType == 3;
}).eq(1);
textNode.replaceWith(document.createTextNode(textNode[0].textContent.replace('[','')));
