document.getElementById("user").innerHTML="Arvin";
</script>
</body>
</html>
but the result is
Name :
Arvin
what I want is
Name : Arvin
thanks for spending your time to read this..any help will much appreciated
Every tag supports id. In your case, <span> would work well.
document.getElementById("user").innerHTML="Arvin";
Name : <span id="user">user1</span>
This code goes wrong because paragraph are shown into a new line (by browser).
This code put text in two lines (without your Javascript)
<html>
<body>
Name : <p id="user">user1</p>
</body>
</html>
You maybe shoud better do this:
<html>
<body>
<p>Name : <span id="user">user1</span></p>
</body>
</html>
document.getElementById("user").innerHTML="Arvin";
See running example here:
I cannot think of any tag that wouldn't support the id attribute, neither can the HTML5 spec:
3.2.5 Global attributes
The following attributes are common to and may be specified on all
HTML elements (even those not defined in this specification): ... id
...
Try adding display: inline style in <p> tag and your problem is solved. You can use id calling on any tag though.
<!DOCTYPE html>
<html>
<body>
Name : <p id="user" style="display:inline;">user1</p>
<script>
document.getElementById("user").innerHTML="Arvin";
</script>
</body>
</html>

I'm really new in Wordpress, Javascript and HTML so I know this question is really basic, but I wasn't able to find it solved anywhere.
I want to create some variables in javascript and then display them in my page which is created in Wordpress.
Reading other posts I've found I need to insert a javascript code that at the end stores my variable this way (dummy version):
<script type="javascript">
document.getElementById('test').innerHTML = 'hello';
</script>
And then on the text block I want to display my variable to be displayed I should add this code:
<body>
<p id="test"></p>
</body>
However I've tried adding the javascript in the header (Tatsu header) and also tried adding it in the text block (HTML version) in different combinations and it never worked. Tried adding the script block before and after the body block, and also tried having it inside, before and after the display line.
If I try the following it works:
<body>
<p>hello</p>
</body>
So I guess my problem is that I'm not setting the variable properly.
Can anyone help? Apologies if this is already solved somewhere, spent some hours and wasn't able to find it.
Thank you in advance.
Your problem is the type of which you're using here:
<script type="javascript">
I noticed this whilst constructing an example of this problem.
javascript is not a correct mime type.
It should be text/javascript as per https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types
Please note this is not a complete list. Such as application/javascript also being valid. Please also see https://www.iana.org/assignments/media-types/media-types.xhtml
Working example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
</head>
<body>
<p id="test">
This shouldn't show up
</p>
<script type="text/javascript">
console.log("####### JAVASCRIPT IS RUNNING ######")
document.getElementById('test').innerHTML = 'hello';
</script>
</body>
</html>
Given i have a sample page that looks like this:
<!DOCTYPE html>
<html>
<body>
<h1 aria-controls="name1">heading</h1>
<p aria-controls="name2">paragraph</p>
<span aria-controls="name1">span</span>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</body>
</html>
How would i use jQuery to select the (2) elements with their aria-controls attribute set to name1? (ignoring the fact that the element types are different).
Thank you!
The attribute selector
[aria-controls="name1"]
should work.
Docs: http://api.jquery.com/attribute-equals-selector/
Use something like this -
WORKING DEMO
var elements = $("body").find("[aria-controls='name1']");
Above is for if you want to look for elements within a container eg body in this case, it can be some div also.
--OR--
var elements = $("[aria-controls='name1']");
Above is for if you want to get all the elements with this attribute
When you search for how to set a paragraph or header element's text dynamically, you keep coming across pretty much the same line of code:
document.getElementById("header").innerHTML = "some text";
This isn't entirely correct though. Take the following example:
<html>
<head />
<body>
<h1 id="header" />
<p id="p1" />
<script type="text/javascript">
document.getElementById("header").innerHTML = "header";
document.getElementById("p1").innerHTML = "p1";
</script>
</body>
</html>
The first JavaScript line pretty much deletes p1 from the page, even though p1 and header have nothing to do with each other in the raw HTML. When wrapping the second JavaScript line in a try...catch block, the error that's caught is:
document.getElementById(...) is null
The same problem exists when you use textContent instead of innerHTML. I'm a little surprised that everybody is saying that this is how you're supposed to change the text of an element when it really doesn't suit that purpose very well. What's the right way to set this up?
p and h1 are not "empty elements", meaning they're not closed in the same tag that opens them (like img and br). If you write them like that, they're not valid tags and the browser will ignore them (which is why document.getElementById can't find them). Try this instead:
<html>
<head></head>
<body>
<h1 id="header"></h1>
<p id="p1"></p>
<script type="text/javascript">
document.getElementById("header").innerHTML = "header";
document.getElementById("p1").innerHTML = "p1";
</script>
</body>
</html>
Change your html to this :
<h1 id="header"></h1>
<p id="p1"> </p>
And try your JavaScript code now they will work, because they are not empty elements.
I think the main issue you are having is with the way you are setting up the closing tags like so: <h1 id="header"/> with / instead of a closing statement. This is incorrect and you need to close it like so: <h1 id="header"></h1> The same is true for the <p> tag and many others. There are some exceptions to this rule which you can find here:
http://www.w3schools.com/html/html_elements.asp
Here is an example fiddle with the actual result!
http://jsfiddle.net/nd3Dq/
In w3schools Javascript tutorial it states:
The value of the text node can be accessed by the node's innerHTML property, or the nodeValue.
Then I change the following code:
<!DOCTYPE html>
<html>
<body>
<p id="intro">Hello World!</p>
<script>
txt=document.getElementById("intro").childNodes[0].nodeValue;
document.write(txt);
</script>
</body>
</html>
to
<!DOCTYPE html>
<html>
<body>
<p id="intro">Hello World!</p>
<script>
txt=document.getElementById("intro").childNodes[0].innerHTML;
document.write(txt);
</script>
</body>
</html>
But it didn't work, could anyone please let me know did I miss something here? Thanks.
document.getElementById("intro").childNodes[0] is a text node, but only element nodes have innerHTML.
You can use document.getElementById("intro").innerHTML instead (to get the innerHTML of the paragraph instead of of the text inside the paragraph).
Try
txt=document.getElementById("intro").innerHTML;
document.write(txt);
You can access innerHTML directly from the p element:
txt=document.getElementById("intro").innerHTML;
document.write(txt);
Also, try to find an alternative to W3Schools: http://www.w3fools.com/
Change
txt=document.getElementById("intro").childNodes[0].innerHTML;
To
txt=document.getElementById("intro").innerHTML;
http://jsfiddle.net/THMVC/
use only
txt=document.getElementById("intro").innerHTML;
i am planing to make my text box editable...
so i removed the id from the disabled code...
even i tested in fiddle its not working...
providing my cod below....
i am providing part of my code in fiddle i am not able to see the text box...
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("p").click(function(){
$(this).hide();
});
});
</script>
</head>
<body>
<p>If you click on me, I will disappear.</p>
<p>Click me away!</p>
<p>Click me too!</p>
</body>
</html>
You have to use input instead of form:input, browser can render standard html tags and you have to provide standard html.
Live Demo
Change
<input id="behvrName" type="text" cssClass="icwText" path="" />
To
<input id="behvrName" type="text" cssClass="icwText" path="" />
cssClass and are also not standard attributes and you need to change them if you want them to be interpreted and act accordingly by browser. cssClass would be class.
spring:message and form:input are not plain HTML tags; rather, they are pseudo-tags processed by your server-side framework. If you want to use JSFiddle, you must use plain HTML.
Furthermore, your input's id is behvrName, but you're not selecting that. If you want to disable that input, use an appropriate selector $('#behvrName') in the JavaScript portion.
