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 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

So, i have this html code:
<div class = "form_wrappers">
<div class = "form">Hello
</div>
</div>
<a class = "destiny_add">
And jQuery code:
function addBlock() {
$('.destiny_add').on('click', function (e) {
e.preventDefault();
$('.form_wrappers').append($('form'))
});
}
I want to add a lot of <div class = "form"> in <div class = "form_wrappers>
How can i make it?
Now it tottaly does not work
There are a couple of issues with your code.
Your jquery is inside the function 'addBlock' which is never called.
You're missing the dot in your append $('form')
You need to append the html of the element, not the element itself.
I also included your code in the .ready() to make sure the elements are loaded before jquery tries to run it.
See the code below
$(function() {
$('.destiny_add').on('click', function (e) {
$('.form_wrappers').append('<div class="form">'+$('.form').html()+'</div>');
});
})

I am looking to use Jquery append to append text to a pre existing div element. I also want to have several element 'templates' and append more text into those elements (see snippet).
var template = { template1: "<p class='someclass'></p>" },
o = $('.divClass');
o.append(template.template1); // Append text inside P tag
You might want to try something like this:
var template = { template1: $("<p class='someclass'></p>") },
o = $('.divClass');
// Set template and append to container
var currentTemplate = template.template1;
o.append(currentTemplate);
// Get current text and append content to the end
var textNode = currentTemplate.text() + "Append Content";
currentTemplate.text(textNode);
Basically, I create the paragraph as it's own node rather than a text string so I had more flexibility with modifying the element. I would normally wait to append the element to my container until after I was done modifying it, but it will work either way.
You can also skip getting the current text if you don't need to append to what's there. Based on your other comments, you would loop through the bottom part, selecting each template and text node in your object and appending it to the container.
Instead of storing your p element as a string, store it as an element. If it's already created, use getElementByID() or getElementByClassName(), if you are creating it now, use
var myPElement = document.createElement("p");
You can then freely change or append to the text that myPElement contains.
myPElement.innerHTML = "set text equal to this";
myPElement.innerHTML += "append this";

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"); });
