I am looking for a way to replace the text of all the links with an specific class, using javascript (not jquery). I would like all the links with that specific class, to have a generic text such as: "click here".

I would use getElementsByClassName to acquire an array of the links. You can then loop through these elements making any changes required.
Heres a Fiddle that also includes some validation to only chenge the text of anchor tags in case you use targetClass for anything else in other elements.
EDIT: looks like other beat me to it :-) (also fixing type in function)

var links = document.querySelectorAll(".yourclass");
for (var i=0; i<links.length; links++)
{
links[i].innerHTML = "click here";
}

This should do the trick. It's using ES6, so make sure you're using either Chrome Canary or a transpiler like Babel.
Say this is your markup...
<a class="classname" href="#">STUBBED</a>
<a class="classname" href="#">MOCKED</a>
<a class="classname" href="#">PLACEHOLDER</a>
This as your JS should work...
let refs = document.getElementsByClassName('classname');
refs = [].slice.apply(refs);
refs.forEach(ref => ref.innerHTML = 'click here');

function myFunction() {
var c = document.querySelectorAll(".example>a");
for(i=0;i<c.length;i++)
{
c[i].innerHTML = "Click Me!";
}
}
This should do the trick in pure javascript

I'm doing this tutorial and this guy says, "I'm going to create a div..."
$("document").ready(function() {
// fetch the AJAX content
$("#newsContent").load("news.txt");
//$.getJSON("news.json", successFn);
});
function successFn(result) {
$.each(result.newsStories, function(i, item) {
// Didn't quite understand what this line did.
var newsDiv = $("<div class='news'>");
newsDiv.append(item.title);
newsDiv.append(item.content);
// Now understand that this puts the above div in play.
$("#newsContent").append(newsDiv);
});
}
I'm really only worried about this line:
var newsDiv = $('<div class="news">');
I've tried this on jsfiddle, but it doesn't seem to work. This is happening during the construction of an AJAX request if that helps.
My question is, when does newsDiv become part of the DOM?

$('<div class="news">'); will return $ wrapped object corresponds to an html element (in this example, div element) to you. But not created any element at your html. You can simply add this newly created element to your html like,
$('#myNewsContainer').append(newsDiv); // append to the div with id 'myNewsContainer'
$('#myNewsContainer').html(newsDiv); // replace all html with new div

The line
var newsDiv = $('<div class="news">');
creates a variable newsDiv with value <div class="news">. At this moment it is not appended to html. You can append it to HTML using Jquery append() method.

I am trying to remove script tag from Html Code using JavaScript.
Here is the HTML Code :
<script type='text/x-template-handlebars' id='carousel_ui_buttons_next-nav_next'>
<button class="next nav" asg-button>{{{button_text}}}</button>
</script>
I want to remove script tag so the remaining part would be html only.
I mean code should be changed inside browser.

it would be better if you provided us with the code you currently have to help you understand what happened rather than using the code copy/paste ,anyway to fire the js code you first decide when you want it to kick in
when the page finish loading ?
$(window).load(function() {
$('#carousel_ui_buttons_next-nav_next').remove();
});
or when the page is ready
$(document).ready(function($) {
$('#carousel_ui_buttons_next-nav_next').remove();
});
or if you prefer you can make it as a function and call it as much as
you want instead of repeating the same code over and over everywhere
function hideScript() {
$('#carousel_ui_buttons_next-nav_next').remove();
});
// then use it like //
$(document).ready(function($) {
hideScript();
});
the above code use JQuery which is much easier than vanilla js to understand and to work with.

The content of your <script> tag is invalid Javascript, but here is one possible way of achieving what you are after:
// Function to convert an HTML string to a DOM element
String.prototype.toDOM = function () {
var d = document,
i,
a = d.createElement('div'),
b = d.createDocumentFragment();
a.innerHTML = this;
while (i = a.firstChild) {
b.appendChild(i);
}
return b;
};
// The <script> we wish to replace
var st = document.getElementById('carousel_ui_buttons_next-nav_next');
// Replace it with the <button> that is inside of it
st.parentNode.replaceChild(st.innerHTML.trim().toDOM(), st);

On my page I have a a couple of tables containing product information and their authors. I also have a div containing the hyperlinks for each author. Right now I'm linking the authors names to a hyperlink using javascript:
<script>
onload = myfun;
function myfun(){
var show =document.getElementById('2364').innerHTML;
var link = document.getElementsByClassName('2364');
var item = link[0];
var item2 = link[1];
document.getElementById('2364').innerHTML=item.outerHTML+'; '+item2.outerHTML;
}
</script>
My problem is that I need to get the elements IDs dynamically and I am not sure how to go about this.
EDIT:
Smarty creates the html, here's a part of it:
<tr><td class="PLContent"><span class="manufacturer"><div id={$module_data.PRODUCTS_ID}>
<h3 id={php}echo $e++;{/php}>{$module_data.PRODUCTS_MANUFACTURER_NAME}{$MANUFACTURER_LINK}</h3></div></span>
Dynamic IDs means that when a user clicks on an author the page will be populated with different products and those products will have a different ID.

Thanks for the answers guys, they gave me some ideas. I managed to solve my problem in the following way:
Added an element that contains only the products ID
Changed my code to this:
.
var t1 = document.getElementById('1').innerHTML;
var link = document.getElementsByClassName(t1);
document.getElementById(t1).innerHTML = link[0].outerHTML;
As I have 10 products per page I'll write this function for each product changing the IDs. It may not be very neat but it's doing the job.
HTML:
<div id={$module_data.PRODUCTS_ID}>
<p>{$module_data.PRODUCTS_MANUFACTURER_NAME}</p>
<p id={php}echo $e++;{/php}>{$module_data.PRODUCTS_ID}</p>
</div>

Simply you can add a class name to your elements and then get all IDs (assuming your are familiar with jQuery).
<tr><td class="PLContent"><span class="manufacturer"><div class="mydiv" id={$module_data.PRODUCTS_ID}>
<h3 class="myh3" id={php}echo $e++;{/php}>{$module_data.PRODUCTS_MANUFACTURER_NAME}{$MANUFACTURER_LINK}</h3></div></span>
To get IDs:
$(".mydiv").each(function() { alert($(this).attr("id"); });
or
$(".myh3").each(function() { alert($(this).attr("id"); });

I am kinda new to Javascript and Jquery and all I wanted to do is a simple test for a navigation bar. I am trying to figure out why my Jquery doesnt work at all...and when I erase my 2 first lines of Javascript, everything works fine...what the hell??? Someone can explain me why is it like this??
My html :
<div id="navbar">
<ul class="ulbar">
<li id="libar">a
<div id="navbar2"></div>
</li>
</ul>
</div>
My JS and Jquery (on same .js):
var buttonA = document.getElementById("libar");
var buttonB = document.getElementById("navbar2");
$(".libar").click(function(){
$(".navbar2").hide("slow", function() {
alert("test");
});
});
Thank you all

try
$(buttonA).click(function(){
$(".navbar2").hide("slow", function() {
alert("test");
});
});

You are gettin the dom elements BY ID first, and referencing later BY CLASS.

I guess you are not able to differentiate between the "class" and "id" attribute.
// IN JavaScript
var buttonA = document.getElementById("libar").value;
// Using jquery, you shall rewrite it as
var buttonA = $('#libar').val();
So in jquery "id" attribute of html elements are accessed by using "#" where as "class" attributes are access by using ".".
Hope that helps.

try this
var buttonA = document.getElementsByClassName("libar");
var buttonB = document.getElementsByClassName("navbar2");
instead of
var buttonA = document.getElementById("libar");
var buttonB = document.getElementById("navbar2");
I think you have class in your html, not id
OR
You need to add id in html
