I am unable to understand why $('#mdiv input')[1].hide(); does not work and at same time why $('#mdiv input')[1].click(); works fine?
Firstly I want to know why? Secondly how to make it working without having the id of the element?
Here is JSFiddle Link to see what i am trying and what I need
That's because you are converting the jQuery object to DOM element object which has no hide method, your second code works as DOM element object has click method like jQuery object. You can use eq method instead which returns a jQuery object.
$('#mdiv input').eq(1).hide();
If you not want to select tags by id, you can use
$('input[name="firstname"]')...
// or
$('input[type="text"][name="firstname"]')...

I am trying to change inner html of an element. If we use this:
$('.best-photos-button')[0].innerHTML="Add More Photos";
it works fine. But if instead of ".innerHTML" i.e. JavaScript if we use .html() like this :
$('.best-photos-button').html("Add More Photos");
then it's not working. Why so?
When I am running $('.best-photos-button').innerHTML on console it's giving undefined.
$('.best-photos-button') is a jQuery object. When you use $('.best-photos-button')[0] it will return the raw DOM element, which does not have a .html() method, only .innerHtml.
So you either need to use
$('.best-photos-button').html("Add More Photos");
or use .innerHtml
Edit:
Note that if you use .html() it will affect all the elements with best-photos-button class. So depending on your use case you might need to use a different selector or filter the selection to get the specific object you need.
I'm trying to trigger a click on one of the navigation dots from another DOM element, but I can't seem to do it a la the following:
$('li.dot')[0].click();
Any help is appreciated.
EDIT: Sorry I don't usually use jQuery. I forgot you need to use first, or first-child, or something of the type to get the node from the jQuery object, not use el[0].
$('li.dot').first().trigger('click');
I know how to do the opposite. Getting a certain DOMElement for a jQuery element is easy. (Use the get() method)
But how can you get a jQuery element for a specific DOMElement?
Unfortunately this DOMElement does not have any attributes like class or id so constructing a selector is not really an option.
Lets say I have this html:
<div class="edit">Abcd<b><i><u>asdasd</u>adasda</i></b>sdfsdf<br>asd</div>
I am in the u-DomElement. How can I get this as a jQuery element?
Is there a smart way to do this?
EDIT:
I wanted to know if there is a gerneral way to do this. Not specific to the code shown above.
Like:
DomElement.toJQuery()
Is there anything like that? I am aware that this might not be possible.
Getting a jQuery object for a DOM object is as simple as jQuery(dom_node) (or $(dom_node)). See http://api.jquery.com/jQuery/
This is commonly used in event handlers, which are given the DOM node as this, so that you will often see $(this)
If you want to get just the Element use the below code. if you wanted to get the HTML of any element you might want to add the .html() tag to either of the examples
var myVar = $('.edit u');
or
var myVar = $(".edit").find("u");
Are you looking for this?
$(".edit").find("u");
hope this is what you are looking for,
$(DomElement)
you want a only 1 specific dom element i suggest you find a way to add an id to that element.
but to get an u element inside a edit class:
$('.edit u');
$('.edit').find('u');
How can I get jQuery to return a html element exactly the way that getElementById does?
if I console.log($('#container')) I will get :
[<div id="container"></div>]
But the API I am interacting with obviously doesn't want that (an array) - it wants :
<div id="container"></div>
I know I can achieve this with $('#container').get(0) and a few other ways, It just seems overkill - especially as I'm selecting an ID which will always be unique.
What am I missing guys?
Thanks
If you just want a single DOM element, then just use plain javascript:
var obj = document.getElementById("container");
jQuery selectors always create a jQuery object with an array of elements in it. That's just the way it's designed. If you want a single element, you either get the first element out of the jQuery object or you use a different tool.
From a jQuery object, you can get the first object either with:
$('#container').get(0)
or with:
$('#container')[0]
But, I would argue that both are more than you need if all you want is the single object that has an id. Just use document.getElementById(). If you want less typing, you could make your own short function:
function $$(id) {
return(document.getElementById(id));
}
var obj = $$("container");
try using .html() it will return the html of the element your selecting see:
http://api.jquery.com/html/
If I do this-
alert(anchor);
I get this-
"[object HTMLLIElement]"
... ok, yep, it is the element I want. So I want to get that elements ID.
So I test it like this:
alert(anchor.attr("id"));
... but I don't get any alert, nothing. I must not be selecting an element. What am I doing wrong, what don't I understand?
There are two problems:
.attr() is a function jQuery objects have, you have a DOM element (you would need $(anchor) to use jQuery methods against the element).
You don't need it anyway, the .id property will work (and be much faster), like this:
alert(anchor.id);
That's because attr is not a defined method or property on anchor. anchor is a raw HTML element object. It's not a jQuery object (I'm assuming you're using jQuery because you used the attr method).
To get the id, all you have to do is anchor.id. If you really want to use attr, you can do jQuery(anchor).attr("id").
if you are using jquery, then you need this:
alert($(anchor).attr("id"));
The attr() function is part of jQuery, but you're trying to get it from a plain DOM object. You either want to use $(anchor) (to wrap the element in jQuery) or call anchor.getAttribute("id") instead.
