I want to put a div in another div using js. I found a solution can do this but just put 1 div in div. Below html is my situation.
For example:
<body>
<div>
<span class="outer_part">
</span>
<div class="inner_part">1
</div>
</div>
<div>
<span class="outer_part">
</span>
<div class="inner_part">2
</div>
</div>
<div>
<span class="outer_part">
</span>
<div class="inner_part">3
</div>
</div>
</body>
Result:
<body>
<div>
<span class="outer_part">
<div class="inner_part">1</div>
</span>
</div>
<div>
<span class="outer_part">
<div class="inner_part">2</div>
</span>
</div>
<div>
<span class="outer_part">
<div class="inner_part">3</div>
</span>
</div>
</body>
I found solution but not work
<script>
$('.inner_part').appendTo('span.outer_part');
</script>
Your problem is that you appending all the .inner_part elements to all the .outer_part elements, but you only need to do a portion of that.
You can use each() to loop over all the .inner_parts, and attach each to its previous sibling, which is the .outer_part.
// loop over all inner parts
$('.inner_part').each(function() {
var innerPart = $(this);
var outerPart = innerPart.prev(); // inner part's previous sibling is the outer part
innerPart.appendTo(outerPart);
});
Or, shorter:
$('.inner_part').each(function() {
$(this).appendTo($(this).prev());
});
Get element by the ID, then add html inside of it to add a div in this case or anything you want.
document.getElementById('div1').innerHTML += '<div class="inner_part">1</div>';
<div id="div1"></div>

<div class="icon-list-item">

I would like to hide/remove any div that contains a span with "empty" content
I have tried many functions but none of them worked. Can you help me find some JS that can solve this?
Explanation : The forEach iterates through all the div elements having class icon-list-item. The spanChild variable holds the child element of the div element of current iteration. remove() function is used to remove element from DOM, when the text inside spanChild is "empty".
var divs = document.querySelectorAll('.icon-list-item');
divs.forEach((el) => {
let spanChild = el.children[0];
if(spanChild.innerText.trim() === "empty")
el.remove();
});
<div class="icon-list-item">
<span class="icon-list-text">One</span>
</div>
<div class="icon-list-item">
<span class="icon-list-text">Two</span>
</div>
<div class="icon-list-item">
<span class="icon-list-text">Three</span>
</div>
<div class="icon-list-item">
<span class="icon-list-text">empty</span>
</div>
I have a div which I want to surround with an <a href>. I have the jQuery to add the <a href> after the div but I struggle to set it before and close it after the div.
This is the jQuery code I have:
$('.box_service').each(function() {
var link = $(this).html();
$(this).contents().wrap('');
});
It results in this HTML:
<div class="row">
<div class="box_service">
<a href="example.com">
<div class="inner-row"></div>
</a>
</div>
</div>
However my goal is this structure:
<div class="row">
<a href="example.com">
<div class="box_service">
<div class="inner-row"></div>
</div>
</a>
</div>
I can't enter the div before because there are more boxes in this row so I would add the <a href> to everything in there
The issue is due to your call to contents() which means you're wrapping the elements inside .box_service, not that element itself. Remove that method call.
Also note that each() is redundant, you can do what you require in a single line:
$('.box_service').wrap('');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
Box service #1
<div class="inner-row">Inner row #1</div>
</div>
</div>
<div class="row">
<div class="box_service">
Box service #2
<div class="inner-row">Inner row #2</div>
</div>
</div>
.content will wrap the contents of your div, you want to wrap the div with <a> so call wrap on the div not on contents.
$('.box_service').each(function() {
var link = $(this).html();
$(this).wrap('');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
<div class="inner-row"></div>
</div>
</div>
$('.box_service').each(function() {
var link = $(this).html();
$(this).wrap('');
});
You just need to remove contents() in between $(this).wrap() because contents() mean that you are wrapping the children of $(this).
Remove .contents() in order to wrap around each element with the class box-service:
$('.box_service').each(function() {
$(this).wrap('');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
<a href="example.com">
<div class="inner-row"></div>
</a>
</div>
</div>
$('.box_service').wrap('');
I am trying to refactor and make a performance wise code.
The idea of the code is to update the id or value of all element with id or value that needs to be updated that happens when an element has been removed / deleted
So what I am trying to do is get all element with Id or value inside a container element (which is possible to be nested in 2 to 4).
At the moment, I am using jQuery to this task. I added a class on every element that has Id and use jQuery .find() to get all of this element using the class I've assign to them .. which is I really hate about my code and wanted to change as well if there's another best way to do it.
So is there a fastest way and performance wise at the same time to do this task?
$("button").on("click", function(){
$($(this).val()).remove();
updateParagraph();
});
function updateParagraph() {
$(".paragraphs").each(function(index, data){
var dataId = data.id.split("-");
var idIndex = dataId[dataId.length-1];
var index = index + 1;
if (index != idIndex) {
dataId.splice(-1, 1);
dataId.push(index);
dataId = dataId.join("-");
$(this).attr("id", dataId);
setChildElementsId($(this), index)
}
});
}
function setChildElementsId(parent, inx) {
$(parent).find(".id-holder").each(function(index, data){
if (data.id) {
var dataId = data.id.split("-");
dataId.splice(-1, 1);
dataId.push(inx);
dataId = dataId.join("-");
$(this).attr("id", dataId);
if(isParagraph(data.tagName)) {
$(this).text(inx);
}
}
else if (data.value) {
var dataValue = data.value.split("-");
dataValue.splice(-1, 1);
dataValue.push(inx);
dataValue = dataValue.join("-");
$(this).val(dataValue);
}
});
}
function isParagraph(tagName){
return tagName == "P";
};

If I understand your question correctly, you're looking to more elegantly identify which elements have an id of the form "__-id-#" or simply "id-#".
If this is the case, take a look at some more advanced jQuery selectors. One in particular which might meet your needs is the Attribute Contains Selector.
For instance, I think $(parent).find("[id*='id-']") might do what you're looking to do.
While I understand what you're attempting to do, I don't quite understand why you're doing this in the first place.
Unless there are restrictions that force you to structure your HTML like you did, well, don't. Aim for the simplest structure:
<div id="container-123" class="paragraphs">
<h4>Header</h4>
<p>1</p>
<button type="button">delete</button>
</div>
Remove the <div>s around the <h4> and the <p> unless you need them for some styling reason. The <button> doesn't need to know its ID, because it's a child element of the container, so you're delete handler could make use of that fact:
$(document.body).on("click", "button", function() {
$(this).closest('.paragraphs').remove();
});
If there are outside forces that require a specific ID (e.g. for linking to an anchor), keep that on the top container element. If your CSS targets elements by ID, refactor the CSS.
I would like to answer your question using javascript. In fact you don't need any of those id-s
I hope I'm not too late.
let buttons = Array.from(document.querySelectorAll(".id-holder"));
buttons.forEach(b => {
//for each button add an event listener
b.addEventListener("click", () => {
b.parentElement.parentElement.removeChild(b.parentElement);
resetNums();
});
});
function resetNums(){
// reseting the text inside the p
let btns = Array.from(document.querySelectorAll(".id-holder"));
btns.forEach((bt,i)=>{
let theP = bt.parentElement.querySelector("p");
theP.innerHTML = i+1;
})
}
<div>
<div>
<h4>Header1</h4>
</div>
<div>
<p>1</p>
</div>
<button class="id-holder">delete</button>
</div>
<div>
<div>
<h4>Header2</h4>
</div>
<div>
<p>2</p>
</div>
<button class="id-holder">delete</button>
</div>
<div>
<div>
<h4>Header3</h4>
</div>
<div>
<p>3</p>
</div>
<button class="id-holder">delete</button>
</div>
<div>
<div>
<h4>Header4</h4>
</div>
<div>
<p>4</p>
</div>
<button class="id-holder">delete</button>

<div>
<div>

</div>
<div>
<p>5</p>
</div>
<button class="id-holder">delete</button>

I have the following structure of my HTML code:
<div id="bb-bookblock" class="bb-bookblock">
<div class="bb-item">
<div class="bb-custom-side">
Hello
</div>
<div class="bb-custom-side">
<button id="add">Click Here to add The page</button>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is first page</p>
</div>
<div class="bb-custom-side">
<p>Hello</p>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is second Page</p>
</div>
<div class="bb-custom-side">
<p>This is last page</p>
</div>
</div>
</div>
When I click on button with id=add I want to create the a new div after the last bb-item div with same two div inside it having class name bb-custom-side.
I know how to create the div using createElement and it a class, but I don't know how to create the sub div inside that newly created div. Can I associate with the last child or similar concept?
So after click event I want my HTML to be something like this:
<div id="bb-bookblock" class="bb-bookblock">
<div class="bb-item">
<div class="bb-custom-side">
Hello
</div>
<div class="bb-custom-side">
<button id="add">Click Here to add The page</button>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is first page</p>
</div>
<div class="bb-custom-side">
<p>Hello</p>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is second Page</p>
</div>
<div class="bb-custom-side">
<p>This is last page</p>
</div>
</div>
<--Newly created div-->
<div class="bb-item">
<div class="bb-custom-side">
new div
</div>
<div class="bb-custom-side">
new div 2
</div>
</div>
</div>
Use clone() to create copy of div elements and append it to main div:
$("#add").click(function(){
var clonedDiv = $(".bb-item:last").clone();
clonedDiv = clonedDiv.find("div.bb-custom-side p").text("This is third Page");
$("#bb-bookblock").append(clonedDiv);
});
DEMO FIDDLE
NOTE: I just updated text for last div (This is third Page). You have to put it in loop to increase number.
Try this.
$('#add').on('click',function(){
$('.bb-item').eq(1).append($('.bb-item:last-child').html());
});
OR
$('#add').click(function(){
$('.bb-item').eq(1).append($('.bb-item:last-child').html());
});
Working Demo
You can try this.
$(document).ready(function () {
$("#add").click(function () {
$("#bb-bookblock").append('<div class="bb-item"><div class="bb-custom-side"> new div</div><div class="bb-custom-side">new div 2</div></div>');
});
});
DEMO
This may not appeal to everyone, but, personally, I tend to like "blank slates" for my cloning.
If it were me, I would do this:
var $baseItem = $("<div></div>").addClass("bb-item");
var $baseCustomSide = $("<div></div>").addClass("bb-custom-side");
$("#add").click(function(){
var $newItem = $baseItem.clone();
$newItem.append($baseCustomSide.clone().html("your_first_content_here"));
$newItem.append($baseCustomSide.clone().html("your_second_content_here"));
$("#bb-bookblock").append($newItem);
});
Unless there is a really good reason to reuse an existing element, I find you end up having to be a lot more complex to "scrub" the existing content from the clone . . . using a blank template always seems more clean to me.
I have created a document with html. I want to retrieve child node from the root node for that I am using following code...
That is HTML.
<a id="Main1" onclick="RetrieveElement(this);">Test1
<div name="Top1">
</div>
<div name="Middle1">
I'm Middle.
</div>
<div name="Bottom1">
</div>
</a>
<a id="Main2" onclick="RetrieveElement(this);">Test2
<div name="Top1">
</div>
<div name="Middle1">
I'm Middle.
</div>
<div name="Bottom1">
</div>
</a>
javascript.
function RetrieveElement(element){
alert(this.getElementByName("Middle1").innerHTML);
}
However, That is not working. I have tried finding the problem but cant solve it... Any help ?
If you want to get the first child element only:
var element = document.getElementById('Main1').children[0];
If you want to get the first anchor element:
var element = document.getElementById('Main1').getElementById('Middle1');
getElementById is a method of Document, not Element. Try this:
<script type="text/javascript">
function RetrieveElement(element){
window.alert(document.getElementById("Middle1").innerHTML);
}
</script>
<a id="Main1" href="#" onclick="RetrieveElement(this);">Test1</a>
<div id="Top1">
</div>
<div id="Middle1">
I'm Middle.
</div>
<div id="Bottom1">
</div>
Can you use jQuery?
It would be as easy as this
