jQuery append method inserting text rather than HTML - javascript

I want append an input text in my html page. I use JQuery to do that.
My JQuery script :
$(document).ready(function(){
$(".reply").click(function(){
var tempat=$(this).parent().parent().next(".komentar-balasan");
console.log(tempat[0]);
var html=
tempat[0].append('<input type="text"></input>');
});
});
And the HTML :
<div class="isi">
<div class="like-comment">
<div class="kotak"></div>
<div class="kotak-jumlah">
</div>
<div class="kotak"><button class="reply"></button></div>
</div><div class="komentar-balasan"></div>
The Fiddle
I Don't know why, but instead of displayed the input text box. The browser just display <input type="text"></input>. It's like the browser didn't recognize the HTML code.

It's because tempat[0] is accessing the underlying DOM node rather than the jQuery wrapper. It works fine if you omit the array access and just call append on tempat.
You don't need it here but the right way to get a jQuery wrapped element of a jQuery selector list is to use eq

The problem is that you aren't calling the append element on a jQuery object (which treats strings as HTML), but instead on a native DOM element. The experimental ParentNode#append method treats strings as text, so you are seeing text.
If you omit the [0] before calling append, your code runs perfectly:
$(document).ready(function() {
$("#post-komentar").click(function() {
console.log($(this).siblings('.editor-komentar').val());
});
$(".reply").click(function() {
var tempat = $(this).parent().parent().next(".komentar-balasan");
console.log(tempat[0]);
var html =
tempat.append('<input type="text"></input>');
});
});
.reply {
background-color: #fff;
width: 20px;
height: 20px;
margin: 0;
padding: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="isi">
<div class="like-comment">
<div class="kotak"><</div>
<div class="kotak-jumlah">
</div>
<div class="kotak"><button class="reply"></button></div>
</div>
<div class="komentar-balasan"></div>

Hello,
Check if this is what you need:
You need to create an element and only then add it.
Here is an example:
$(document).ready(function(){
$(".reply").click(function(){
var tempat=$(this).parent().parent().next(".komentar-balasan");
console.log(tempat[0]);
var newEl = document.createElement('input');
newEl.type = "text";
tempat.append(newEl);
});
});
I hope I have helped!

Remove the [0]. You are dereferencing your jQuery object by doing that.
This works: tempat.append('<input type="text"></input>');

Drop event from outside window only fires the second time

I am drag-and-dropping some text from a proprietary application into an HTML <textarea> element. This software cannot copy-paste; drag-and-drop is the only option. However, the drag and drop can be simulated by simply typing a few lines in Word, then dragging them into the browser.
I have a jsfiddle with my code. However, when I drag some lines from the program into the text box the first time, I get "undefined" returned. When I try it again without reloading the page (when the text area already has contents), it works great.
How can I get it to work the first time?
You need to put the line
$('#return').html(dropstr);
inside of the getAsString callback.
var dropstr;
$( document ).ready(function() {
$('#dropbox').on('drop', function(e) {
e.originalEvent.dataTransfer.items[0].getAsString(function(str){
dropstr=str;
console.log(dropstr);
$('#return').html(dropstr);
});
});
});
#return{
border:1px solid black;
width: 200px;
height: 50px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="dropbox" contenteditable="true" id="dropbox">
<textarea></textarea>
</div>
<div id="return">
</div>
You were appending outside of callback which itself is not needed at least in your case. fiddle
<div id="dropbox" contenteditable="true" id="dropbox">
<textarea></textarea>
</div>
<div id="return">
</div>
and here is js.
var dropstr;
$(document).ready(function() {
$('#dropbox').on('drop', function(e) {
var str = e.originalEvent.dataTransfer.getData('Text');
console.log(str);
$('#return').html(str);
});
});

Check if a div is disabled jQuery

I need to check whether myDiv1 is disabled. If so, I need to hide myDiv2, otherwise I need to show myDiv2.
Here is what I have so far:
$(document).ready(function () {
var isDisabled = $('#myDiv1').is('[disabled=disabled]')
alert(isDisabled); //this always returns false
if(isDisabled)
$("#myDiv2").hide();
else
$("#myDiv2").show()
});
But isDisabled return always false even when myDiv1 is enabled. What am I missing here?
So many answers, but none addressing the actual problem: A div element doesn't allow an attribute of type disabled. On a div only global attributes are allowed, whereas disabled is allowed on form elements.
You can easily verify it by testing this HTML:
<div id="a" disabled></div>
<input id="b" disabled>
against this JavaScript:
var e = $('#a');
alert(e.is(':disabled'));
var e = $('#b');
alert(e.is(':disabled'));
Which will return false and true.
What's a solution then?
If you want to have an attribute that is actually named disabled use a data-* attribute:
<div id="c" data-disabled="true"></div>
And check it using this JavaScript:
var e = $('#c');
alert(e.data('disabled'));
or:
var e = $('#c');
alert('true' === e.attr('data-disabled'));
Depending on how you're going to handle attached data-*-attributes. Here you can read more about jQuery's .data() which is used in the first example.
Demo:
Try before buy
The reason why isDisabled returns false to you is, because you have most likely set the following in your HTML:
<div id = "myDiv1" disabled>...</div>
In reality, disabled means disabled = "", so, since "disabled" != "", if you keep using $('#myDiv1').is('[disabled=disabled]') you will always get false.
What will work:
To make this work, as other answers have mentioned, you can use:
$('#myDiv1').attr('disabled') == "disabled" (#guradio answer),
$('#myDiv1').is('[disabled=""]') or
$('#myDiv1')[0].getAttribute("disabled") != null.
What won't work:
While $('#myDiv1')[0].getAttribute("disabled") != null will work regardless of what element the attribute is set on, on the other hand, $('#myDiv1')[0].disabled will only work on 'form elements' and will return undefined for all others (check out the note at the end).
The same occurs when you use $('#myDiv1').is(':disabled') as well.
Alternatively, if you want to keep your code intact, you can set disabled = "disabled" in your HTML and the problem will be solved.
Working Example (using 2.):
/* --- JavaScript --- */
$(document).ready(function(isDisabled) {
isDisabled = $('#myDiv1').is('[disabled=""]');
if (isDisabled) $("#myDiv2").hide();
else $("#myDiv2").show()
/* Will return 'true', because disabled = "" according to the HTML. */
alert(isDisabled);
});
<!--- HTML --->
<script src = "//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id = "myDiv1" disabled>DIV 1</div>
<div id = "myDiv2">DIV 2</div>
Note: Beware, however, that the disabled attribute is meant to be used with 'form elements' rather than anything else, so be sure to check out the very informative answer of #insertusernamehere for more on this. Indicatively, the disabled attribute is meant to be used with the following elements:
button,
fieldset (not supported by IE),
input,
keygen (not supported by IE),
optgroup (supported by IE8+),
option (supported by IE8+),
select and
textarea.
$('#myDiv1').attr('disabled') == "disabled" ? $("#myDiv2").hide() : $("#myDiv2").show();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='myDiv1' disabled="true">1</div>
<div id='myDiv2'>2</div>
Try this way. But i dont think div has disable attribute or property
$('#myDiv1[disabled=true]').length > 0 ? $("#myDiv2").hide() : $("#myDiv2").show();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='myDiv1' disabled="true">1</div>
<div id='myDiv2'>2</div>
Using attribute selector
attribute selector
Description: Selects elements that have the specified attribute with a value exactly equal to a certain value.
First you need to set disabled property for your div
<div id="myDiv" disabled="disabled">This is Div</div>
Then you need to use this
$('#myDiv1').is('[disabled=disabled]')
Use this one:
$(document).ready(function () {
if($('#myDiv1').is(':disabled'))
$("#myDiv2").hide();
else
$("#myDiv2").show()
});
I hope this will help you:
$(document).ready(function () {
var isDisabled = $('#myDiv1').is(':disabled')
if(isDisabled)
$("#myDiv2").hide();
else
$("#myDiv2").show()
});
Use $("#div1").prop("disabled") to check whether the div is disabled or not. Here is a sample snippet to implement that.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<style>
.container {
width: 100px;
height: 100px;
background: grey;
margin: 5px;
float: left;
}
div {
width: 100%;
float: left;
}
</style>
</head>
<body>
<div>
<input type="checkbox" id="ChkBox" onclick="UpdaieDivStatus()" /> Toggle access
</div>
<div id="div1" class="container">Div 1</div>
<div id="div2" class="container">Div 2</div>
<script>
function UpdaieDivStatus() {
if ($("#ChkBox").prop('checked')) {
$("#div1").prop("disabled", true);
} else {
$("#div1").prop("disabled", false);
}
if ($('#div1').prop('disabled')) {
$("#div2").hide();
} else {
$("#div2").show();
}
console.log($("#div1").prop("disabled"));
}
</script>
</body>
</html>
If you look at this MDN HTML attribute reference, you will note that the disabled attribute should only be used on the following tags:
button, command, fieldset, input, keygen, optgroup, option, select,
textarea
You can choose to create your own HTML data-* attribute (or even drop the data-) and give it values that would denote the element being disabled or not. I would recommend differentiating the name slightly so we know its a custom created attribute.
How to use data attributes
For example:
$('#myDiv1').attr('data-disabled') == "disabled"
Why don't you use CSS?
html:
<div id="isMyDiv" disabled>This is Div</div>
css:
#isMyDiv {
/* your awesome styles */
}
#isMyDiv[disabled] {
display: none
}
Set the disabled attribute on any HtmlControl object. In your example it renders as:
<div id="myDiv1" disabled="disabled"><div>
<div id="myDiv2" ><div>
and in javascript can be checked like
('#myDiv2').attr('disabled') !== undefined
$(document).ready(function () {
if($('#myDiv1').attr('disabled') !== undefined)
$("#myDiv2").hide();
else
$("#myDiv2").show()
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script>
<div id="myDiv1" disabled="disabled">Div1<div>
<div id="myDiv2" >Div1<div>

Add element to document and then remove it using Jquery

I am adding text to an element in Jquery using
$('.alert-saved').append('<br />See more like this >>')
I then show this to the user and pause.
$('.alert-saved').delay(5000).fadeOut(2000);
I would now like to remove all the text I appended.
I have tried this but it didn't work
$('.alert-saved').remove('<br />See more like this >>')
Just pass an empty HTML string argument:
$('.alert-saved').html('');
EDIT 1
If you need to keep other elements, you can use this method:
var newLine = jQuery('<br />See more like this');
jQuery(".alert-saved").append(newLine);
setTimeout(function() {
jQuery(newLine).remove();
}, 2000)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="alert-saved">
<span>I wanna stay!</span>
</p>
Change your code to :
$('.alert-saved').append('<div id="divId"><br />See more like this >></div>');
And while removing you can use :
$('.alert-saved').remove('#divId');
With the help of divId you can easily remove your appended element/string from '.alert-saved'.
Check the below code it will work as expected -
$('.alert-saved').append('<div class="testing" <br />See more like this >> </div>')
$('.alert-saved').delay(5000).fadeOut(2000);
$('.alert-saved').remove('.testing')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="alert-saved"></div>
You could try this also :
$('.alert-saved').next().remove();
You can wrap your element in an tagged element with a class, or a custom tag, and then delete it accordingly like:
var release_id = 'demo'
$('.alert-saved').append('<div class="added"><br />See more like this >></div>')
setTimeout(function() {
$('.alert-saved>.added').remove();
}, 5000);
Demo: https://jsfiddle.net/Lxy83r43/
Whatever you append append with a class like this and remove all at once using .remove()
Checkout the demo below
$('.yes').click(function(){
$('.alert-saved').append('<div class ="added" ><br />See more like this >>');
})
$('.me').click(function(){
$('.added').remove();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="alert-saved">
asdasdasdas
</div>
<input type="button" class="me" value="remove"/>
<input type="button" class="yes" value="add"/>
An easy way to do this work is adding class or id to appended element.
But if you don't want to do this, you can store new elements in variable and append it using .appendTo() to html document like this:
var HTML = $("<br><a>New link</a>");
$(HTML).appendTo('.alert-saved');
When you want to remove elements, use bottom code.
HTML.remove();
var HTML = $("<br><a>New link</a>");
$(HTML).appendTo('.alert-saved');
setTimeout(function(){
HTML.remove();
}, 2000);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="alert-saved">
<a>Old link</a>
</div>

Document.write alternatives examples

I have been using document.write to generate the HTML part of my page, populating it using a loop. For example I need to create 10 of the following things on my page:
<div class=" normal" id="1"
style="text-align:left;
top: 13px;
left: 5px;
height: 10em;
width: 12em;">
<div class = "wrap">
<div class = "show">
<strong>New York City
<p>Status: Cold</p>
</strong>
</div>
<div class = "noshow">
<P>0001: Normal</P>
</div>
<div class = "here">
<P>0001: online</P>
<P>0002: online</P>
</div>
</div>
</div>
I been doing :
<script>
document.write("<div class=\"");
.. you get the idea</script>
What is another way to do this with jquery or just not-document.write? Could you also provide short example applied onto the code I have above.
Jquery .html() Could be good for this purpose.
<script>
$(function() {
var htmlString = "<div>.. you get the idea</div>";
$("body").html(htmlString);
});
</script>
or this will append html:
.append()
<script>
$(function() {
var htmlString = "<div>.. you get the idea</div>";
$("body").append($(htmlString));
});
</script>
Put the entire thing in a variable :
say : var html_content = "<div class=.....";
and in your loop you can simply use .append(html_content);
You could use DOM manipulation to directly query and add node elements to the DOM.

Javascript creating <div> on the fly

I have a a link that looks similar to this
Blog
As you can the link has an ID of 'blog' what I want to do is to create an div on the fly with the ID from the link that was clicked so if the 'blog' is clicked, then the markup would be
<div id="blog">
<!--some content here-->
</div>
Like wise if for instance the news link is clicked then I would like,
<div id="news">
<!--some content here-->
</div>
to be created in the markup if this possible? and how Im pretty new to jQuery.
Try this:
$("a").click(function(){
$("#wrapper").append("<div id=" + this.id + "></div>");
});
Not tested, should work ;)
where: #wrapper is parent element, work on all a as you see.
You will need to give the div a different ID. Perhaps you could give it a class instead:
$("#blog").click(function() {
$(this).after("<div class='blog'>...</div>");
return false;
});
That's just one of many ways to create a div. You probably also want to avoid duplicates however in which case, use something like this:
$("#blog").click(function() {
var content = $("#blog_content");
if (content.length == 0) {
content = $("<div></div>").attr("id", "blog_content");
$(this).after(content);
}
content.html("...");
return false;
});
As for how to handle multiple such links I would do something like this:
Blog
News
Weather
<div id="content"></div>
with:
$("a.content").click(function() {
$("#content").load('/content/' + this.id, function() {
$(this).fadeIn();
});
return false;
});
The point is this one event handler handles all the links. It's done cleanly with classes for the selector and IDs to identify them and it avoids too much DOOM manipulation. If you want each of these things in a separate <div> I would statically create each of them rather than creating them dynamically. Hide them if you don't need to see them.
Try This :
<a id="blog">Blog</a>
<a id="news">news</a>
<a id="test1">test1</a>
<a id="test2">test2</a>
$('a').click(function()
{
$('<div/>',{
id : this.id,
text : "you have clicked on : " + this.id
}).appendTo("#" + this.id);
});
First of all you should not make 2 elements with same ID. At your example a and div will both have id="blog". Not XHTML compliant, plus might mess up you JS code if u refernce them.
Here comes non-jquery solution (add this within script tags):
function addDiv (linkElement) {
var div = document.createElement('div');
div.id = linkElement.id;
div.innerHTML = '<!--some content here-->';
document.body.appendChild(div); // adds element to body
}
Then add to HTML element an "event handler":
Blog
This question describes how to create a div. However, you shouldn't have two elements with same IDs. Is there any reason why you can't give it an id like content_blog, or content_news?
Unfortunately if you click on a link the page you go to has no idea what the idea of the link you clicked was. The only information it knows is what's contained in the URL. A better way to do this would be to use the querystring:
Blog
Then using the jQuery querystring plugin you could create the div like:
$("wrapper").add("div").attr("id", $.query.get("id"));
You shouldn't have elements in your page with the same ID. Use a prefix if you like, or perhaps a class.
However, the answer is as follows. I am imagining that your clickable links are within a div with the ID "menu", and your on-the-fly divs are to be created within a div with the ID "content".
$('div#menu a').click(function(){
$('div#content').append('<div id="content_'+this.id+'"><!-- some content here --></div>');
});
Any problems, ask in the comments!
Also the following statement is available to create a div dynamically.
$("<div>Hello</div>").appendTo('.appendTo');
Working fiddle: https://jsfiddle.net/andreitodorut/xbym0bsu/
you can try this code
$('body').on('click', '#btn', function() {
$($('<div>').text('NewDive').appendTo("#old")).fadeOut(0).fadeIn(1000);
})
#old > div{
width: 100px;
background: gray;
color: white;
height: 20px;
font: 12px;
padding-left: 4px;
line-height: 20px;
margin: 3px;
}
