jQuery .append() multiple #id's with one line? - javascript

I'm using the jQuery .append() function to input content into HTML elements via their id like so;
function returnGameDetailed(data) {
$('#game-synopsis').append(data.results.deck);
}
For some of the data.results I need to append them to multiple elements, is there a correct method to do this?
In the documentation I can only see a method for multiple inputs to the same element, not reversed.
Here's what i've attempted;
$('#game-title').$('#purchase-amazon').append(data.results.name);
and
$('#game-title', '#purchase-amazon').append(data.results.name);

You were almost right. The correct way is here:
$('#game-title, #purchase-amazon').append(data.results.name);
However, I'd recommend you to use classes instead:
$('.elements-to-insert').append(data.results.name);
<div class="elements-to-insert" id="game-title"></div>
<div class="elements-to-insert" id="purchase-amazon"></div>

Give both elements a class and then append to that class
$('.className').append(data.results.name);
The elements having the className will get appended with the html

Find element in document using HTML DOM

I need to be able to select and modify an element in an HTML document. The usual way to find an element using jQuery is by using a selector that selects by attribute, id, class or element type.
However in my case I have the element's HTML DOM and I want to find the element on my document that matches this DOM.
Important :
I know I can use a class selector or ID selector etc.. but sometimes the HTMLs I get don't have a class or an ID or an attribute to select with, So I need to be able to select from the element's HTML.
For example here is the element I need to find :
<span class='hello' data='na'>Element</span>
I tried to use jQuery's Find() but it does not work, here is the jsfiddle of the trial : https://jsfiddle.net/ndn9jtbj/
Trial :
el = jQuery("<span class='hello' data='na'>Element</span>");
jQuery("body").find(el).html("modified element");
The following code does not make any change on the element that is present in my HTML and that corresponds to the DOM I have supplied.
Is there any way to get the desired result either using native Javascript or jQuery?
You could filter it by outerHTML property if you are sure how browser had parsed it:
var $el = jQuery("body *").filter(function(){
return this.outerHTML === '<span class="hello" data="na">Element</span>';
});
$el.html("modified element");
el = jQuery('<i class="fa fa-camera"></i>');
This does not say "find the element that looks like <i class="fa fa-camera"></i>". It means "create a new i element with the two classes fa and fa-camera. It's the signature for creating new elements on the fly.
jQuery selectors look like CSS, not like HTML. To find the i element with those two classes, you need a selector like i.fa.fa-camera.
Furthermore $("document") looks for an HTML element called document. This does not exist. To select the actual document, you need $(document). You could do this:
$(document).find('i.fa.fa-camera').html("modified html")
or, more simply, you could do this:
$('i.fa.fa-camera').html('modified html');
You indicate in a comment to your question that you need to find an element based on a string of HTML that you receive. This is, to put it mildly, difficult, because, essentially, HTML ceases to exist once a browser has parsed it. It gets turned into a DOM structure. It can't just be a string search.
The best you can do is something like this:
var searchEl = jQuery('<i class="fa fa-camera"></i>');
var tagName = searchEl.prop('tagName');
var classes = [].slice.apply(searchEl.prop('classList'));
$(tagName + "." + classes.join('.')).html('modified html');
Note that this will only use the tag name and class names to find the element. If you also want IDs or something else, you'd need to add that along the same lines.
You should use Javascript getting the elements by something like
document.getElementById...
document.getElementsByClassName...
document.getElementsByTagName...
Javascript is returning the elements with the Id, Class or Tag Name you chose.
You can get en element with document.querySelector('.fa-camera')
with querySelector you can select IDs and Classes
You can simply refer to it by its class names.
$('.fa.fa-camera').html("modified html");
Similar to this answer https://stackoverflow.com/a/1041352/409556
Here is a full example:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('.fa.fa-camera').html("modified html");
});
</script>
</head>
<body>
<i class="fa fa-camera"><h1>Some HTML</h1></i>
</body>
</html>`
The one thing that you could use is to check attributes (class and id goes here too in some way) that element have, and the build jQuery selector or DOM querySelector to find the element you need. The hardest part would be to find element based on innerHTML property - "Element" text inside it, for this one you'll probably have to grab all similar element and then search through them.
<span class='hello' data='na'>Element</span>
jQuery('body').find('span.hello[data=\'na\']').html('modified element')
Take notice of 'span' - that's tag selector, '.hello' - class, '[data="na"]' data attribute with name of data.

Select a div insinde another div with jQuery

So I try to select a div within another div. My html goes like this:
<div id="Stage_game_page1"><div id="cube0">[...]</div><div id="cube1">[...]</div></div>
I want to select my #cube0 within my Stage_game_page specifically, with jQuery or JS.
The goal of the selection is to use it in an loop.
I tried :
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#Stage_game_page")$("#cube"+i)[...]
}
I don't understand what I'm doing wrong.
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#cube"+i);
}
This is sufficient to select the "#cube0"/"#cube1"/"#cube2" etc. especially since ids are always unique. To answer the question $("#cube0", "#Stage_game_page")... that is how you select a div in another div
The id attribute should only be used once! I see above that you're using id="cube0" twice. If you want your divs to be recognized in multiple instances, use a class instead (the . instead of the #). Using the same id twice will probably break your script.
I believe for your html, you could use id "cube0", "cube1", etc., as long as you're ok with entering them manually. That should work for the loop you'd like to use.
Loops through each div that starts with the id cube inside Stage_game_page1
$("#Stage_game_page1 > div[id^='cube']").each(function () {
alert($(this).html());
});
JSFiddle
Child Selctor
Starts with Selector
use each() for loop.
$('#Stage_game_page1').children().each(function(index) {
// your code here with index starts from 0
});
or this using jquery attribute starts with selector
$('#Stage_game_page1').find('[id^="cube"]').each(function(index) {
// your code here
});
You need to use .find() or .children() or the like.
The correct jQuery usage would be
$("#Stage_game_page").find('#cube'+i)
to find a div with that id inside the container #stage_game_page
You have duplicate cube0 in your html code..
and i think the look should contain something like that:
$("#cube"+i)[...]
One another solution is:
$("#Stage_game_page1 div[id='cube0']")

Im forcing to use getElementsByClassName()[] rather than getElementByClass()

I have 8 divs with id="div1","div2","div3".... and a class=divs. I also have a button with class="div1","div2","div3"......
When I click the button with id="div1", it will first remove all the class="selected" to all div that has a class="divs" then only the div with id="div1" will have the class selected. And so on.....
I want to use document.getElementByClass() for removing class but it don't work in my FIDDLE. :(
Instead, Im forced to use document.getElementsByClassName()[]. But it seems so hard to code since it requires me to put the specific arrays for the classname.
This is exactly I want to achieve FIDDLE
There is no getElementByClass for a reason: unlike id, class is not specified to be unique in a document. Which element would you get? No, you need the ability to get all of them. And if you get an array, that's solved by looping, not by repeating rows for each index:
However, your design is inefficient; and if you're already using jQuery, you can write it very tightly. This would be better:
<button class="divbuttons" data-div="div1">div1</button>
<button class="divbuttons" data-div="div2">div2</button>
...
then you can:
$(document).ready(function(){
$('.divbuttons').click(function() {
var div = $(this).data("div");
$('.divs.selected').removeClass('selected');
$('#' + div).addClass('selected');
});
});
This is an easy one. There is no document.getElementByClass
You have document.getElementById or document.getElementByClassName
There's no such thing as getElementByClass() because multiple elements can have the same class. There's getElementById() (elements have unique ids, or at least they're supposed to) and getElementsByClassName(), which returns an array of all elements that match the class specified.
try
$(document).ready(function () {
$("button[class^=div]").click(function () {
$(".divs.selected").removeClass("selected");
$("#" + $(this).attr("class")).addClass("selected");
});
});

How to .append() an object

I'm making a simple game in javascript and I would like to .append() a box. To serve as a bullet. But I'm stuck. This is what I have
var existingdiv1 = document.getElementById('bullet');
and
$("#test").click(function() {
$("div").append([existingdiv1]);
});
It wont create additional "divs" when I press the button "#test".
You will have to select the existing div (I guess this is the bullet?). Then append it.
Here's and example:
Working Demo
Javascript:
$("#test").click(function(){
$("#appendToThis").append($('#bullet').html());
});
Html:
<input id="test" type="button" value="click" />
<div id="appendToThis"></div>
<div id="bullet"><div>BANG</div></div>
You will see the word "bang" be appended everytime you click. You can remove it by using the empty() method on the test div.
From the .append documentation:
If an element selected this way is inserted into a single location elsewhere in the DOM, it will be moved into the target (not cloned).
It seems like you want to clone [docs] the element first:
$("div").append($(existingdiv1).clone());
// or simpler
$("div").append($('#bullet').clone());
Note though that if you have multiple div elements on your page, $("div") will select all of them and the element you pass to .append will cloned automatically (as stated in the documentation).
You should append the element only to a single div.
I believe you wanted to add a new div to the existing div, so your code has been reversed the append order. and you need wrap the existing div by $('#bullet')
Try this
$('#bullet').append('<div></div>');
You can use .clone()
$("#test").click(function(){
$("#appendToThis").append($('#bullet').clone());
});

Remove attribute of HTML tag

Is it possible to remove the attribute of the first HTML <div> tag? So, this:
<div style="display: none; ">aaa</div>
becomes
<div>aaa</div>
from the following:
<div style="display: none; ">aaa</div>
(bbb)
<span style="display: none; ">ccc</span>​
Or pure JavaScript:
document.getElementById('id?').removeAttribute('attribute?')
To remvove it from literally the first element use .removeAttr():
$(":first").removeAttr("style");
or in this case .show() will show the element by removing the display property:
$(":first").show();
Though you probably want to narrow it down to inside something else, for example:
$("#container :first").removeAttr("style");
If you want to show the first hidden one, use :hidden as your selector:
$(":hidden:first").show();
Yes, in fact jQuery has something for this purpose: http://api.jquery.com/removeAttr/
You can use the removeAttr method like this:
$('div[style]').removeAttr('style');
Since you have not specified any id or class for the div, the above code finds a div having inline style in it and then it removes that style from it.
If you know there is some parent element of the div with an id, you can use this code instead:
$('#parent_id div[style]').removeAttr('style');
Where parent_id is supposed to be the id of parent element containing the div under question.
You say "remove the attribute" — do you mean to remove all attributes? Or remove the style attribute specifically?
Let's start with the latter:
$('div').removeAttr('style');
The removeAttr function simply removes the attribute entirely.
it is easy in jQuery just use
$("div:first").removeAttr("style");
in javascript
use var divs = document.getElementsByTagName("div");
divs[0].removeAttribute("style");
