I have a element with a child of an empty paragraph. That looks like this. Photo for easier viewing.
<body contenteditable="true" class="cke_editable cke_editable_themed cke_contents_ltr cke_show_borders" spellcheck="true">
<p><br></p>
</body>
How do I edit the area between the two p's using javascript to what ever I want since there is no id on them.
var onlineContent = document.getElementsByClassName("cke_editable cke_editable_themed cke_contents_ltr cke_show_borders");
All I have so far is this.
If you are using Jquery you can try this :
$(".cke_editable p:first").html("The text has changed");
You can also read more about how jQuery :first Selector works here: http://www.w3schools.com/jquery/sel_first.asp
document.getElementsByClassName returns an array-like object so you need to select with:
var onlineContent = document.getElementsByClassName("cke_editable cke_editable_themed cke_contents_ltr cke_show_borders")[0];
var onlineContentInner = onlineContentOuter.getElementsByTagName("p")[0];
the 0-th (meaning first) element.
An alternative method is given with document.querySelector(A_VALID_CSS_SELECTOR) wich return only the first element found (equals document.querySelectorAll(CSS_SELECTOR)[0]).
A valid css selector would be .cke_editable.cke_editable_themed.cke_contents_ltr.cke_show_borders
and your element would be (using document.querySelector):
var onlineContentInner = document.querySelector(".cke_editable p");
There you have it.
It would be like this.
var onlineContent = document.getElementsByTagName("body")[0];
onlineContent.getElementsByTagName("p")[0].innerHTML = "Content between the p tags";

I've searched around using Google and Stack Overflow, but I haven't seemed to find a answer to this. I want to write text inside a <div> element, using JavaScript, and later clear the <div> element, and write more text into it. I am making a simple text adventure game.
This is what I am trying to do:
<DOCTYPE!HTML>
<body>
<div class="gamebox">
<!-- I want to write in this div element -->
</div>
</body>
As a new user to JavaScript, how would I be able to write inside the div element gamebox? Unfortunately, my JavaScript skills are not very good, and it would be nice if you can patiently explain what happens in the code.
You can use querySelector to get a reference to the first element matching any CSS selector. In your case, a class selector:
var div = document.querySelector(".gamebox");
querySelector works on all modern browsers, including IE8. It returns null if it didn't find any matching element. You can also get a list of all matching elements using querySelectorAll:
var list = document.querySelectorAll(".gamebox");
Then you access the elements in that list using 0-based indexes (list[0], list[1], etc.); the length of the list is available from list.length.
Then you can either assign HTML strings to innerHTML:
div.innerHTML = "This is the text, <strong>markup</strong> works too.";
...or you can use createElement or createTextNode and appendChild / insertBefore:
var child = document.createTextNode("I'm text for the div");
div.appendChild(span); // Put the text node in the div
Those functions are found in the DOM. A lot of them are now covered in the HTML5 specification as well (particularly Section 3).
Select a single element with document.querySelector or a collection with document.querySelectorAll.
And then it depends, on what you want to do:
Writing Text into the div or create an Element and append it to the div.
Like mentioned getElementsByClassName is faster. Important to know it when you use this you get returned an array with elements to reach the elment you want you specify its index line [0], [1]
var gameBox = document.getElementsByClassName('gamebox')[0];
Here how you can do it
//returns array with elements
var gameBox = document.getElementsByClassName('gamebox');
//inner HTML (overwrites fsd) this can be used if you direcly want to write in the div
gameBox[0].innerHTML ='<p>the new test</p>';
//Appending when you want to add extra content
//create new element <p>
var newP = document.createElement('p');
//create a new TextNode
var newText = document.createTextNode("i'm a new text");
//append textNode to the new element
newP.appendChild(newText);
//append to the DOM
gameBox[0].appendChild(newP);

I have a div set up something like this:
<div id="test"> <p>Hello</p> <p style="display: none">Goodbye</p> </div>
EDIT: To clarify, this is the simplest example. The div could have any arbitrary number of n deep nested children.
$('#test').getText() returns 'Hello Goodbye'. Here's a one liner to test in Firebug: jQuery('<div id="test"> <p>Hello</p> <p style="display: none">Goodbye</p> </div>').text()
This seems to be because what jQuery uses internally, textContent (for non IE), returns hidden elements as part of the text. Hrmph.
Is there a way to return the text content ignoring display:none'd elements? Basically I am trying to mimic the text you would get from highlighting the div with your mouse and copying to system clipboard. That ignores hidden text.
Interestingly, if you create a selection range and get the text from it, that also returns text inside display:none elements.
var range = document.body.createTextRange();
range.moveToElementText($('#test')[0]);
range.select();
console.log(range.toString()); // Also logs Hello Goodbye!
So creating a document selection range doesn't appear to do the same thing as highlighting with the mouse in terms of display:none elements. How do I get around this dirty pickle conundrum?
Edit: using .filter(':visible').text has been suggested, but it won't work for this scenario. I need the returned text to be EXACTLY what would come from a selection with the mouse. So for example:
$('<div>test1 <p>test2</p>\r\n <b>test3</b> <span style="display:none">none</span></div>').appendTo(document.body).children().filter(':visible').text()
returns
"test2test3"
When the output I actually want is
test1 test2
test3
linebreaks, whitespace and all, which come from the \r\n
Filter the elements using .filter(":visible").
Or use this:
$("#test :visible").text();
But the jQuery documentation advises us to use .filter() instead:
Because :visible is a jQuery extension and not part of the CSS specification,
queries using :visible cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :visible to select elements, first select the elements using a pure CSS selector, then use .filter(":visible").
Use :visible in your selector as such:
$("#test > p:visible").text()
A Function example:
-- Edit:
http://jsfiddle.net/8H5ka/ ( Works on Chrome it displays "Hello" in Result )
If the above doesn't work:
http://jsfiddle.net/userdude/8H5ka/1/
If space isn't a major concern you could copy the markup, remove the hidden elements, and output that text.
var x = $('#test').clone();
x.filter(':not(:visible)').remove();
return x.text();
I had this problem and found this question, and it seems the actual solution is based on the provided answers but not actually written out. So here's a complete solution that worked for my situation, which is the same as the OP with the additional provision that elements may be invisible due to external styles based on DOM position. Example:
<style>.invisible-children span { display: none; }</style>
<div class="invisible-children">
<div id="test">Hello <span>Goodbye</span></div>
</div>
The solution is to:
Make a clone of the entire object.
Remove invisible objects in place; if we take #test out of the DOM before we remove invisible objects, jQuery might not know they're invisible because they will no longer match the CSS rules.
Get the text of the object.
Replace the original object with the clone we made.
The code:
var $test = $('#test');
// 1:
var $testclone = $test.clone();
// 2: We assume that $test is :visible and only remove children that are not.
$test.find('*').not(':visible').remove();
// 3:
var text = $test.text();
// 4:
$test.replaceWith($testclone);
// Now return the text...
return text;
// ...or if you're going to keep going and using the $test variable, make sure
// to replace it so whatever you do with it affects the object now in DOM and
// not the original from which we got the text after removing stuff.
$test = $testclone;
$test.css('background', 'grey'); // For example.
Here is how I did it with MooTools:
$extend(Selectors.Pseudo, {
invisible: function() {
if(this.getStyle('visibility') == 'hidden' || this.getStyle('display') == 'none') {
return this;
}
}
});
Element.implement({
getTextLikeTheBrowserWould = function() {
var temp = this.clone();
temp.getElements(':invisible').destroy();
return temp.get('text').replace(/ |&/g, ' ');
}
})
I search for that and found this question but without solution.
Solution for me is just get out of jquery to use DOM:
var $test = $('#test').get(0).innerText
or if more than on element in array of selector, you need a for loop and a merge but I guess that most of time it is the first version that you need.
var $test = $('#test').get().map(a => a.innerText).join(' ');

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.
(Answer partially copied from: jQuery document.createElement equivalent?)
For instance in the snippet below - how do I access the h1 element knowing the ID of parent element (header-inner div)?
<div id='header-inner'>
<div class='titlewrapper'>
<h1 class='title'>
Some text I want to change
</h1>
</div>
</div>
Thanks!
function findFirstDescendant(parent, tagname)
{
parent = document.getElementById(parent);
var descendants = parent.getElementsByTagName(tagname);
if ( descendants.length )
return descendants[0];
return null;
}
var header = findFirstDescendant("header-inner", "h1");
Finds the element with the given ID, queries for descendants with a given tag name, returns the first one. You could also loop on descendants to filter by other criteria; if you start heading in that direction, i recommend you check out a pre-built library such as jQuery (will save you a good deal of time writing this stuff, it gets somewhat tricky).
If you were to use jQuery as mentioned by some posters, you can get access to the element very easily like so (though technically this would return a collection of matching elements if there were more than one H1 descendant):
var element = $('#header-inner h1');
Using a library like JQuery makes things like this trivial compared to the normal ways as mentioned in other posts. Then once you have a reference to it in a jQuery object, you have even more functions available to easily manipulate its content and appearance.
If you are sure that there is only one H1 element in your div:
var parent = document.getElementById('header-inner');
var element = parent.GetElementsByTagName('h1')[0];
Going through descendants,as Shog9 showed, is a good way too.
It's been a few years since this question was asked and answered. In modern DOM, you could use querySelector:
document.querySelector('#header-inner h1').textContent = 'Different text';
<div id='header-inner'>
<div class='titlewrapper'>
<h1 class='title'>
Some text I want to change
</h1>
</div>
</div>
The simplest way of doing it with your current markup is:
document.getElementById('header-inner').getElementsByTagName('h1')[0].innerHTML = 'new text';
This assumes your H1 tag is always the first one within the 'header-inner' element.
To get the children nodes, use obj.childNodes, that returns a collection object.
To get the first child, use list[0], that returns a node.
So the complete code should be:
var div = document.getElementById('header-inner');
var divTitleWrapper = div.childNodes[0];
var h1 = divTitleWrapper.childNodes[0];
If you want to iterate over all the children, comparing if they are of class “title”, you can iterate using a for loop and the className attribute.
The code should be:
var h1 = null;
var nodeList = divTitleWrapper.childNodes;
for (i =0;i < nodeList.length;i++){
var node = nodeList[i];
if(node.className == 'title' && node.tagName == 'H1'){
h1 = node;
}
}
Here I get the H1 elements value in a div where the H1 element which has CSS class="myheader":
var nodes = document.getElementById("mydiv")
.getElementsByTagName("H1");
for(i=0;i<nodes.length;i++)
{
if(nodes.item(i).getAttribute("class") == "myheader")
alert(nodes.item(i).innerHTML);
}
Here is the markup:
<div id="mydiv">
<h1 class="myheader">Hello</h1>
</div>
I would also recommend to use jQuery if you need a heavy parsing for your DOM.
