I'm trying to only select ARTICLE items that do not have the style attribute set.
I could do this easily with jQuery but I'm using a library that is javascript only, called scrollreveal.
I can easy get items that have the style attribute using this ARTICLE[style].
But I want to reverse this and get items that do not have a style attribute, in the same way using a not equal to != operator on the selector.
I've tried this...
// scroll reveal article
window.sr = new ScrollReveal({ reset: false });
sr.reveal('ARTICLE[!=style]', {
duration: 1000
});
But it's not working as expected, does anyone know if its possible to achieve this using not equal too on a attribute selector?
Thanks in advance for any help on this.
Almost there. The :not pseudoclass should do the trick:
article:not([style])
Just use :not([style]):
const matches = document.querySelectorAll('div:not([style])')
console.log(matches)
<div id="foo" style="width:100px;"></div>
<div id="bar"></div>
<div id="baz"></div>
That is if I'm correct in assuming that sr.reveal uses document.querySelector internally.
I am creating a variable that stores an elements ID in the variable. I could write it like this:
var webappData = document.getElementById('web-app-data');
If I wanted to do the same using jQuery I think I would write it like this:
var webappData = $('#web-app-data');
However, when I try that it doesn't work. (Script throws an error because the variable isn't selecting the div with that Id.)
How would I use jQuery to select an element and store it in a variable?
document.getElementById('web-app-data') isn't the same as $('#web-app-data'). The later returns jQuery object, which is kind of an array of HTMLElement objects (only one in your case).
If you want to get HTMLElement, use $('#web-app-data')[0]. Check:
document.getElementById('web-app-data') === $('#web-app-data')[0]; // true
It's ok.. Maybe something else is wrong in your code..
Example:
<div id="web-app-data">
Hello
</div>
<script type='text/javascript'>
var webappData = $('#web-app-data');
alert(webappData.text()); // Hello
</script>
Fiddle
Above code should work just fine. Your problem might be, that jQuery doesn't find any corresponding elements from the DOM since the element has been removed or hasn't been loaded there yet. If you try to
console.log($('#web-app-data'));
that variable, you can check if jQuery actually found anything. jQuery object should have lenght of (atleast) one if corrensponding element is indeed in DOM atm.
That will work and you use just like it was the full JQuery selector.
var elm = $('#webappData');
if (elm.hasClass('someClass')) elm.removeClass('someClass');
return;
Edit: one missing piece of information - I can't use the class selector because there are more divs with the same class. I already thought of that, but I forgot to mention it. I have no idea why my post got downvoted, but it seems awfully silly considering I provided a lot of information, gave it honest effort, and tried to be verbose with code examples. People on this forum are ridiculous sometimes.
I'm trying to set the id of a div that doesn't have one and there's no way I can give it one upon generation of the page. I've tried using jquery (.each, .contains, .find, .filter, etc.) and I can't seem to get it right. I know a ton of people have asked this question, but none of the answers made sense to me.
I have the ability to set the text (html?) of the div, but nothing else. It ends up looking like this:
<div class="dhxform_note" style="width: 300px;">Remaining letters: 500</div>
I want a handle to the div object so I can show the user how many more letters they can type by updating the text.
Using this:
$("div")
returns a list of all divs on the page. I can see the target div in the list, but I can't get jquery to return a single object.
I know it can also be done with something like this:
var divs = document.getElementsByTagName("div");
for(var i = 0; i < divs.length; i++) {
if( /^Remaining letters/.test(divs[i].innerText) )
divs[i].id = "kudosMsgNote"
}
}
but I was hoping to complete this with a cleaner looking solution involving jquery. I also simply want to know how to do it with jquery, aesthetics not withstanding.
Use a class selector.
var theDivViaTheClass = $(".dhxform_note");
Class Selector (“.class”)
Description: Selects all elements with the given class.
version added: 1.0
jQuery( ".class" )
class: A class to search for. An
element can have multiple classes; only one of them must match.
For class selectors, jQuery uses JavaScript's native
getElementsByClassName() function if the browser supports it.
You seem to be targeting the <div> by its text. Try using the :contains selector:
$("div").filter(':contains("Remaining letters")').first().attr("id", "kudosMsgNote");
The .first() is to make sure you don't set the same id for multiple elements, in case multiple elements contain the text "Remaining letters".
Here's the docs for the :contains selector: http://api.jquery.com/contains-selector/
Be careful, the text you're looking for is case sensitive when using :contains!
Is that div the only one with the class dhxform_note? If so, you can use the class selector:
$('.dhxform_note').html();
With jQuery, you can specify any css selector to get at the div:
$(".dhxform_note").attr("id", "kudosMsgNote");
will get you this element as well.
Selecting on inner text can be a bit dicey, so I might recommend that if you have control over the rendering of that HTML element, you instead render it like this:
<div name="remainingLetters" class="dhxform_note" style="width: 300px">Remaining Letters: 500</div>
And get it like this:
$("[name=remainingLetters]").attr("id", "kudosMsgNote");
However, it's possible that you really need to select this based on the inner text. In that case, you'll need to do the following:
$("div").each(function() {
if ( /^Remaining letters/.test($(this).html()) ) {
$(this).attr("id", "kudosMsgNote");
}
});
If you cannot set id for whatever reason, I will assume you cannot set class either. Maybe you also don't have the exclusive list of classes there could be. If all those assumptions really apply, then you can consider down your path, otherwise please use class selector.
With that said:
$("div").filter(function() {
return /^Remaining letters/.test($(this).text())
}).attr('id', 'id of your choice');
For situations where there are multiple divs with the class dhxform_note and where you do not know the exact location of said div:
$("div.dhxform_note").each(function(){
var text = $(this).text();
if(/^Remaining letters/.test(text)){
$(this).attr("id", "kudosMsgNote");
}
});
EXAMPLE
If, however, you know that the div will always be the 2nd occurrence of dhxform_note then you can do the following:
$("div.dhxform_note").get(1).id = "kudosMsgNote";
EXAMPLE
Or do a contains search:
$("div.dhxform_note:contains('Remaining letters')").first().attr("id", "kudosMsgNote");
EXAMPLE
I have a div, and I used html() to change its content. I am doing a "cancel" button, and I would like to html() back to the original value.
Is there an efficient way to do this? I'm trying to avoid to html() the whole code again, as it doesn't look very good and is probably not the best practice.
Thanks a lot in advance. Regards
// store the old content
var myOldContent = $("#cancelbutton").html();
// change content
$("#cancelbutton").html(someNewContent);
// and change it back
$("#cancelbutton").html(myOldContent);
If at all possible, don't use .html to toggle content this way -- use two adjacent, nearly-identical elements, one with the old HTML and one with the new, and create a hidden CSS class with display: none and assign it to the second element. Then toggle this hidden class on both elements at the same time.
HTML:
<button class="cancel" id="cancel-original">Cancel</button>
<button class="cancel hidden" id="cancel-second">Cancelling...</button>
CSS:
.hidden {
display: none;
}
JQuery:
$('button.cancel').click(function() {
$('button.cancel').toggleClass('hidden'); // toggles both at once
});
http://jsfiddle.net/e9eLP/
You can clone it when it's made, using jQuery, and when you cancel, delete that and clone the old version back in.
The browser does not track the original value.
However, you can store the original HTML yourself into a variable when the page loads.
You can save the previous HTML content into a variable and then restore from that variable on cancel.
var previousHtml = $('#someElement').html();
Then
$('#someElement').html(previousHtml);
You would need to save it in a variable before changing it:
<script>
var origHTML = $("#divid").html();
function ResetDiv(){
$("#divid").html(origHTML);
}
</script>
By using jQuery's data() function you can easily hold the original value internally, and then restore it with something like this:
$('#a').click(function(){
$('div').data('store',$('div').html()).html('foo');
});
$('#b').click(function(){
$('div').html($('div').data('store'));
});

(Note that this example is just to illustrate how to store a value using data() and not meant for production code.)

jQuery document.createElement equivalent?

How do I create a div element in jQuery?
As of jQuery 1.4 you can pass attributes to a self-closed element like so:
jQuery('<div>', {
id: 'some-id',
class: 'some-class some-other-class',
title: 'now this div has a title!'
}).appendTo('#mySelector');
Here it is in the Docs
Examples can be found at jQuery 1.4 Released: The 15 New Features you Must Know .
You can use append (to add at last position of parent) or prepend (to add at fist position of parent):
$('#parent').append('<div>hello</div>');
// or
$('<div>hello</div>').appendTo('#parent');
Alternatively, you can use the .html() or .add() as mentioned in a different answer.
Technically $('<div></div>') will 'create' a div element (or more specifically a DIV DOM element) but won't add it to your HTML document. You will then need to use that in combination with the other answers to actually do anything useful with it (such as using the append() method or such like).
The manipulation documentation gives you all the various options on how to add new elements.
d = document.createElement('div');
$(d).addClass(classname)
.html(text)
.appendTo($("#myDiv")) //main div
.click(function () {
$(this).remove();
})
.hide()
.slideToggle(300)
.delay(2500)
.slideToggle(300)
.queue(function () {
$(this).remove();
});
div = $("<div>").html("Loading......");
$("body").prepend(div);
$("<div/>").appendTo("div#main");
will append a blank div to <div id="main"></div>
A short way of creating div is
var customDiv = $("<div/>");
Now the custom div can be appended to any other div.
All these worked for me,
HTML part:
<div id="targetDIV" style="border: 1px solid Red">
This text is surrounded by a DIV tag whose id is "targetDIV".
</div>
JavaScript code:
//Way 1: appendTo()
<script type="text/javascript">
$("<div>hello stackoverflow users</div>").appendTo("#targetDIV"); //appendTo: Append at inside bottom
</script>
//Way 2: prependTo()
<script type="text/javascript">
$("<div>Hello, Stack Overflow users</div>").prependTo("#targetDIV"); //prependTo: Append at inside top
</script>
//Way 3: html()
<script type="text/javascript">
$("#targetDIV").html("<div>Hello, Stack Overflow users</div>"); //.html(): Clean HTML inside and append
</script>
//Way 4: append()
<script type="text/javascript">
$("#targetDIV").append("<div>Hello, Stack Overflow users</div>"); //Same as appendTo
</script>
$("<div/>").attr('id','new').appendTo('body');
This will create new div with id "new" into body.
document.createElement('div');
Here's another technique for creating divs with jQuery.
ELEMENT CLONING
Say you have an existing div in your page that you want to clone using jQuery (e.g. to duplicate an input a number of times in a form). You would do so as follows.
$('#clone_button').click(function() {
$('#clone_wrapper div:first')
.clone()
.append('clone')
.appendTo($('#clone_wrapper'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="clone_wrapper">
<div>
Div
</div>
</div>
<button id="clone_button">Clone me!</button>
Create an in-memory DIV
$("<div/>");
Add click handlers, styles etc - and finally insert into DOM into a target element selector:
$("<div/>", {
// PROPERTIES HERE
text: "Click me",
id: "example",
"class": "myDiv", // ('class' is still better in quotes)
css: {
color: "red",
fontSize: "3em",
cursor: "pointer"
},
on: {
mouseenter: function() {
console.log("PLEASE... "+ $(this).text());
},
click: function() {
console.log("Hy! My ID is: "+ this.id);
}
},
append: "<i>!!</i>",
appendTo: "body" // Finally, append to any selector
}); // << no need to do anything here as we defined the properties internally.
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Similar to ian's answer, but I found no example that properly addresses the use of methods within the properties object declaration so there you go.
simply if you want to create any HTML tag you can try this
for example
var selectBody = $('body');
var div = $('<div>');
var h1 = $('<h1>');
var p = $('<p>');
if you want to add any element on the flay you can try this
selectBody.append(div);
<div id="foo"></div>
$('#foo').html('<div></div>');
If you are using Jquery > 1.4, you are best of with Ian's answer. Otherwise, I would use this method:
This is very similar to celoron's answer, but I don't know why they used document.createElement instead of Jquery notation.
$("body").append(function(){
return $("<div/>").html("I'm a freshly created div. I also contain some Ps!")
.attr("id","myDivId")
.addClass("myDivClass")
.css("border", "solid")
.append($("<p/>").html("I think, therefore I am."))
.append($("<p/>").html("The die is cast."))
});
//Some style, for better demonstration if you want to try it out. Don't use this approach for actual design and layout!
$("body").append($("<style/>").html("p{background-color:blue;}div{background-color:yellow;}div>p{color:white;}"));
I also think using append() with a callback function is in this case more readable, because you now immediately that something is going to be appended to the body. But that is a matter of taste, as always when writing any code or text.
In general, use as less HTML as possible in JQuery code, since this is mostly spaghetti code. It is error prone and hard to maintain, because the HTML-String can easily contain typos. Also, it mixes a markup language (HTML) with a programming language (Javascript/Jquery), which is usually a bad Idea.
alternatively to append()
you can also use appendTo() which has a different syntax:
$("#foo").append("<div>hello world</div>");
$("<div>hello world</div>").appendTo("#foo");
You can create separate tags using the .jquery() method. And create child tags by using the .append() method. As jQuery supports chaining, you can also apply CSS in two ways.
Either specify it in the class or just call .attr():
var lTag = jQuery("<li/>")
.appendTo(".div_class").html(data.productDisplayName);
var aHref = jQuery('<a/>',{
}).appendTo(lTag).attr("href", data.mediumImageURL);
jQuery('<img/>',{
}).appendTo(aHref).attr("src", data.mediumImageURL).attr("alt", data.altText);
Firstly I am appending a list tag to my div tag and inserting JSON data into it. Next, I am creating a child tag of list, provided some attribute. I have assigned the value to a variable, so that it would be easy for me to append it.
I think this is the best way to add a div:
To append a test div to the div element with ID div_id:
$("#div_id").append("div name along with id will come here, for example, test");
Now append HTML to this added test div:
$("#test").append("Your HTML");
I hope that helps code. :) (I use)
function generateParameterForm(fieldName, promptText, valueType) {
//<div class="form-group">
//<label for="yyy" class="control-label">XXX</label>
//<input type="text" class="form-control" id="yyy" name="yyy"/>
//</div>
// Add new div tag
var form = $("<div/>").addClass("form-group");
// Add label for prompt text
var label = $("<label/>").attr("for", fieldName).addClass("control-label").text(promptText);
// Add text field
var input = $("<input/>").attr("type", "text").addClass("form-control").addClass(valueType).attr("id", fieldName).attr("name", fieldName);
// lbl and inp => form
$(form).append(label).append(input);
return $(form);
}
If it is just an empty div, this is sufficient:
$("#foo").append("<div>")
or
$("#foo").append("<div/>")
It gives the same result.
$(HTMLelement) can success it. If you want an epmty div use it as $('<div></div>');. Also you can set the other elements by the same method. If you want to change inner HTML after created you can use html() method. For get outerHTML as string you can use is like this :
var element = $('<div/>');
var innerHTML = element.html(); // if you want set new HTML use it like this element.html('<b>new HTML</b>');
var outerHTML = element[0].outerHTML;
You can use .add() to create a new jQuery object and add to the targeted element. Use chaining then to proceed further.
For eg jQueryApi:
$( "div" ).css( "border", "2px solid red" )
.add( "p" )
.css( "background", "yellow" );
div {
width: 60px;
height: 60px;
margin: 10px;
float: left;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
How about this? Here, pElement refers to the element you want this div inside (to be a child of! :).
$("pElement").append("<div></div");
You can easily add anything more to that div in the string - Attributes, Content, you name it. Do note, for attribute values, you need to use the right quotation marks.
I've just made a small jQuery plugin for that.
It follows your syntax:
var myDiv = $.create("div");
DOM node ID can be specified as second parameter:
var secondItem = $.create("div","item2");
Is it serious? No. But this syntax is better than $("<div></div>"), and it's a very good value for that money.
