i am trying to create href using javascript which should have data-role="button". But the button is not showing. Here is my code.
var a = document.createElement("A");
a.appendChild(document.createTextNode("Skúsiť Znova"));
a.setAttribute("onClick","checkConnection();");
a.setAttribute("data-role","button");
a.setAttribute("data-inline","true");
a.setAttribute("data-corner","false");
I append this to div as child and I can see text and also onClick parameter is working great. But for some reason it isnt showing as button but as normaln href. Any suggestions on how to create jquerymobile button dynamicaly with JS? This is whole code:
$(document).ready(function(){
var a = document.createElement("A");
var div = document.createElement("div");
var span = document.createElement("span");
var p2 = document.createElement("p");
var p = document.createElement("p");
a.appendChild(document.createTextNode("Skúsiť Znova"));
a.setAttribute("onClick","checkConnection();");
a.setAttribute("data-role","button");
a.setAttribute("data-inline","true");
a.setAttribute("data-corner","false");
div.setAttribute("id","alertMessage");
span.appendChild(document.createTextNode("Pripojenie zlyhalo"));
p2.setAttribute("style","text-align: center;");
span.setAttribute("class","red");
p.appendChild(span);
p.appendChild(document.createTextNode(" (skontrolujte nastavenia siete)."));
div.appendChild(p);
p2.appendChild(a);
div.appendChild(p2);
var mainDiv = document.getElementById("alert");
mainDiv.appendChild(div);
$('mainDiv').trigger('create');
var toppos=($(window).height()/2) - ($("#alertMessage").height()/2);
var leftpos=($(window).width()/2) - ($("#alertMessage").width()/2);
$("#alertMessage").css("top", toppos).css("left",leftpos);
});
You can use trigger('create') to apply all of the jQuery Mobile formatting. Full working code:
HTML:
<div id="container"></div>
JavaScript:
var a = document.createElement("A");
a.appendChild(document.createTextNode("Skúsiť Znova"));
a.setAttribute("onClick","checkConnection();");
a.setAttribute("data-role","button");
a.setAttribute("data-inline","true");
a.setAttribute("data-corner","false");
$('#container').append(a).trigger('create');
This can be seen in action here: http://jsfiddle.net/sQ2dA/.
In response to your edits: the issue is that you have mainDiv in quotes, so you are passing a string on this line:
$('mainDiv').trigger('create');
But you should be passing the variable mainDiv:
$(mainDiv).trigger('create');
Please see the working example here: http://jsfiddle.net/P62Cp/.
var a = document.createElement("button");
a.innerText = "Submit";
a.id = "addition";
document.body.appendChild(a);

I'm new to HTML and CSS and I hope to get some help here :D.
I want to create an <a> element at a certain div container with the id navigationPaths, which would be this div container.
<div id="navigationPaths">
This is the part of my javascript code which I want to append to this ID. This is what i already found.
var a = document.createElement('a');
var linkText = document.createTextNode("Path");
a.appendChild(linkText);
a.title = "Path";
a.href = "http://google.com";
document.body.appendChild(a);
The functions I found doesn't really suit my problem so I hope that someone here knows how this works.
As a postscript to Phil's comment, if you didn't want to faff around creating DOM elements, you could create some fully-formed HTML by inserting an HTML string into the element.
const anchor = '<a title="path" href="http://google.com">Path</a>';
const el = document.querySelector('#navigationPaths');
el.insertAdjacentHTML('beforeend', anchor);
<div id="navigationPaths">New anchor: </div>
You can just replace document.body.appendChild(a) with document.getElementById('navigationPaths').appendChild(a)
to get a specified element in javascript you can use document.getElementById('navigationPaths') or document.queryselector('#navigationPaths')
then you can save it in a variable then you can append it as a child to it like this
var a = document.createElement('a');
var linkText = document.createTextNode("Path");
a.appendChild(linkText);
a.title = "Path";
a.href = "http://google.com";
const navigation = document.getElementById('navigation');
navigation.appendChild(a);
<div id="navigation"></div>
I want to move an image on another one. I saw on forum, the best way to do this is to use destination.appendChild(elementToMove). But when I use it, my elementToMove just disappears.
Here is a fiddle for what I want to do (but that's not working):
JS Fiddle
Here is my JS Code:
var body = document.getElementsByTagName("body")[0];
var td_sign = document.getElementById("sign");
var td_moon = document.getElementById("moon");
var sign = document.createElement("img");
sign.src="http://img11.hostingpics.net/thumbs/mini_723286sign.png";
var moon = document.createElement("img");
moon.src="http://img11.hostingpics.net/thumbs/mini_418048moon.png";
td_sign.appendChild(sign);
td_moon.appendChild(moon);
var testbutton = document.createElement('input');
testbutton.type='button';
testbutton.value='test';
testbutton.onclick = function(){
sign.appendChild(moon);
}
body.appendChild(testbutton);
I just want to use JavaScript.
I am trying to create a Bootstrap Modal dialog using JavaScript. The reason I am doing it with JavaScript is because I want to be able to render it later using custom elements (i.e. title, error message). I am fairly new to JavaScript so I do not understand why the code is not executed when I call the function errorMessage(). Can anyone please help out by letting me know what the mistake is and how I can correct it? Is there a more efficient way of doing it? Thank you very much.
By the way I did link the modal.js file to the HTML doc and I am aware of bootboxjs, but I don't want to use it for now.
// Creation of the alert message box.
function errorMessage() {
var Modal = document.createElement('div');
Modal.id = 'myModal';
Modal.className = 'modal fade show';
// To set up the attributes.
Modal.setAttribute("data-backdrop", "static");
Modal.setAttribute("data-keyboard", false);
document.body.appendChild(Modal);
var dialog = document.createElement('div');
dialog.className = 'modal-dialog';
Modal.appendChild(dialog);
var content = document.createElement('div');
content.className = 'modal-content';
dialog.appendChild(content);
var header = document.createElement('div');
header.className = 'modal-header';
content.appendChild(header);
var title = document.createElement('h4');
title.className = 'modal-title';
title.createTextNode = 'Data Error';
header.appendChild(header);
var body = document.createElement('div');
body.className = 'modal-body';
dialog.appendChild(body);
var message = document.createElement('p');
message.createTextNode("Oh... snap. We can't find any items in your list. Please make sure your entry is structured as following:");
body.appendChild(message);
var representation = document.createElement('div');
representation.className = 'well';
body.appendChild(representation);
var representationTxt = document.createElement('p');
representationTxt.style.fontStyle = 'italic';
representationTxt.createTextNode('> Subheader , tag1 , tag2, tag3');
representation.appendChild(representationTxt);
var footer = document.createElement('div');
footer.className = 'modal-footer';
dialog.appendChild(footer);
var closeBtn = document.createElement('button');
closeBtn.setAttribute("data-dismiss", "modal");
closeBtn.setAttribute("type", "button");
closeBtn.className = 'btn btn-primary btn-inverse';
closeBtn.value = 'I got it. Thanks.';
footer.appendChild(closeBtn);
// Show modal dialog box
$("#myModal").modal('show');
}
It is failing on this line: header.appendChild(header); because it cannot append header to itself. Did you mean this?
var title = document.createElement('h4');
title.className = 'modal-title';
title.createTextNode = 'Data Error';
header.appendChild(title);
A debugging tool is invaluable in javascript development (Firebug add-on for Firefox or the built-in tools in Chrome, for example). You would have seen this error right away :)
For the last 20 minutes I've been befuddled by such a simple problem that it's almost embarrassing to ask. Basically I want to create an anchor tag for a div which already exists but I want to use the DOM to create the anchor. For some reason I cannot get this simple problem to work. Tried single quotes and double quotes, moving the script tag from head to body, etc...
Here's the code
<html>
<head>
</head>
<body>
<div id = "image_div">
<img src = "my_image.png" />
</div>
<script type="text/javascript">
var DIV = document.getElementById("image_div");
var anchor = document.createElement("a");
anchor.href = "http://www.stackoverflow.com";
DIV.appendChild(anchor);
</script>
</body>
</html>
Your Example is Working Fine.. And also Append your a Child to DOM, but You have to Insert a text and some Sign for that it is Shown to click..
var DIV = document.getElementById("image_div");
var anchor = document.createElement("a");
anchor.href = "http://www.stackoverflow.com";
anchor.innerText = "Click Me";
DIV.appendChild(anchor);
See Fiddle
Or If you wanna Wrap,the a Anchor tag to img then use :
var DIV = document.getElementById("image_div");
var img1 = document.getElementById("img1");
var anchor = document.createElement("a");
anchor.href = "http://www.stackoverflow.com";
anchor.appendChild(img1);
DIV.appendChild(anchor);
WORKING DEMO
You didn't put any text in the anchor so it won't have any size and thus you won't see it even though it's there.
var DIV = document.getElementById("image_div");
var anchor = document.createElement("a");
anchor.href = "http://www.stackoverflow.com";
anchor.innerHTML = "Click Me"; // <==== Add this line
DIV.appendChild(anchor);
I am trying to setup a new "a" component using JS function which is called , using following :
function add_div(data){
mydiv = document.getElementById("new_twt");
var link =document.createElement("a");
var text = "you have new conversations";
link.setAttribute("name",text);
link.onclick=function(){new_tweet(data);};
mydiv.appendChild(link);
}
Changes are not reflecting on the webpage , however if I use some other element such as button or new div it gets created instantly, am I missing something?
This works for me:
function add_div(data){
var mydiv = document.getElementById("new_twt");
var link = document.createElement("a");
var text = "you have new conversations";
link.name = text;
link.href = '#';
link.innerHTML = 'link';
link.onclick=function(){ new_tweet(data); return false; };
mydiv.appendChild(link);
}
I've added link text (innerHTML) so you can actually see the link
I've also added "href" so the link behaves as a link (with this you need to prevent default link action, like "return false" in the event listener, to prevent browser from jumping to the top)
Try this:
var mydiv = document.getElementById("new_twt");
var aTag = document.createElement('a');
aTag.setAttribute('href',"yourlink.htm"); //or #
aTag.innerHTML = "you have new conversations";
aTag.onclick=function(){new_tweet(data);};
mydiv.appendChild(aTag);
Here is working JS Fiddle.
