Using this code, I am trying to get the href attribute of a link and make a new link of that attribute. Why my link does not work, I don't know. It shows something like this:
404 - The page cannot be found
Sorry, we cannot find the page.
It might have been removed, had its name changed, or is temporarily
unavailable.
Please check that the Web site address is spelled correctly.
Or go to our home page, and use the menus to navigate to a specific
section.
Here is my code:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
text ="";
text +=$("#w3s").attr("href");
document.getElementById("demo").innerHTML="<a href=\'text\'>W3Schools.com</a>";
});
});
</script>
</head>
<body>
<p>W3Schools.com</p>
<button>Show href Value</button>
<p id="demo"></p>
</body>
</html>
If I use:
document.getElementById("demo").innerHTML = text;
It shows http://www.w3schools.com. Why doesn't the link go to this site?
If you're going to use jQuery to traverse and manipulate the DOM, use jQuery. If you're going to use vanilla javascript... do that. Just try not mix them! Makes things easier in the long run. Anyway, you could do something like this to set the href attribute;
$('#demo').attr('href', text);
or
document.getElementById('demo').href = text;
btw this
"<a href=\'text\'>W3Schools.com</a>"
Is totally not how you do string concatenation in javascript. Should be
'W3Schools.com'

In my project i have a javascript file that contain a variable like this one:
var htmlcode = "<html><body><h1>My First Web Page</h1><p>My first paragraph.</p></body></html>"
i would to know if in javascript exist a command for render my htmlcode variable ina real html page, i think to use a button for open that page.
So many thanks in advance
Using jQuery, you can use $('html') to select the HTML tag, and change its content using $('html').html("some new content"):
$("#changeHTML").click(function() {
$('html').html("<body><div style='color:red;'>New sample text</div></body>");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<body>
Sample text
<button id="changeHTML">Click me</button>
</body>
</html>
Using plain Javascript, you can use document.documentElement to select the document's HTML tag (source), and changing this variable's innerHTML should do the trick.
Open JavaScript:- this code isn't editable as it is locked by the Host! So also I can't add any selector inside it!
But I can add another code outside of it. Like:- <ex ex="ex">Open JavaScript</ex>
So, I want to create a <script src="/javascript.js"></script> by fetching the URL from Open JavaScript.
They also didn't allow PHP there, otherwise I could do it myself. There is only one way to do it via JavaScript.
And I don't want to add the script inside <head> tags! It should be in the footer (<div class="body-footer"> Here </div>). There are not only one JavaScript link in the page, there are so many JavaScript links. So also I can't use $("a[href$='.js']");. Its became more tougher for me.
So how can I do this using JavaScript or jQuery?
Here is my implementation, where <script> tag is added before <a> with value of href.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
var hrefValue = $("div#test a").attr("href");
$("div#test a").before("<script src='"+hrefValue+"'><\/script>");
console.log($("#test").html());
});
});
</script>
</style>
</head>
<body>
<div id="test">
Open JavaScript
</div>
</br></br>
<button>CLICK it, to add href value of anchor tag to newly created sibling element</button>
</body>
</html>
Is it possible to create your own text contents (text between the HTML tags) of my custom HTML tags?
I used this code:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<script>
$(document).ready(function () {
$("eg").replaceWith("<h2>Put the text content of eg here</h2>");
});
</script>
</head>
<body>
<eg>My text</eg>
</body>
</html>
Between the <h2> tags (don’t think I should only use <h2> tags without JS) in my JavaScript code, any text can be placed that I like to have.
Example: <eg>I can type any text here but it’ll be still in h2 tag settings</eg>.
What should I write between <eg></eg> in JS to have any <h2> text content that will be written in my HTML code?
If you want to replace the <eg>Test</eg> with <h2>Test</h2> then you can just do this: $("eg").replaceWith("<h2>" + $("eg").html() + "</h2>");.
Here is an example: http://plnkr.co/edit/urd69pJSXQngGIsYYSjq
If I'm understanding correctly, you just want to append an element to the DOM, so you can just use the html method as follows:
$("eg").html("<h2>Any text can be placed here</h2>");
Have a look at the docs if you need more info.
Note: You closed but didn't open your body tag.
Replace:
</body>
With something like:
<body> <eg> Your custom content is between body tags now </eg> </body>
And you also have two HTML tags, remove the second
<html>
No. It wouldn't be HTML anymore.
However, if you wrote xHTML (which is a form of XML), then you could extend the DOM with your own elements. But that would be XML, not HTML.
And if you tried adding custom elements to a page, browsers wouldn't know what to do with them. Even if some browsers might display them, it's a very bad idea. Use a class name instead.
Creating and using custom tags is a bad idea. It should be avoided.
You are probably looking for this:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<script>
$(document).ready(function () {
$("#my_h2").html("<h2>Any text can be placed here</h2>");
});
</script>
</head>
<h2 id="my_h2"></h2>
</body>
</html>
For more, read-up on CSS selectors. (They are the same as jQuery selectors.)
Hope this helps.
I have a page where I want to display content from a website inside my app. I have a parser which in this case grab the element from their site and into mine. But I have this problems, the links serverside are like campaign.aspx?wfege, when a users clicks it, I want to add a http://example.com/ before so the link will result in looking like http://example.com/campaign.aspx?wfege. It this possible in javascript? If so, how? Please look at my fiddle, it's fully working and is an exact copy of my site.
Fiddle: http://jsfiddle.net/4vdck/
Cheers
This can be done in your HTML.
You need to add the base tag with the appropriate href, like this
<html>
<head>
<base href="http://example.com/" target="_blank">
....
....
</head>
<body>
ClickHere <!-- Because of the base tag this href will lead you to http://example.com/campaign.aspx?wfege -->
....
</body>
</html>
I want to get content of script tag example
now see above in src property load bolo7.com content i want to catch that contain
i have try so many method but it doesn't work
try 1 -> document.getElementById("data").innerHTML; //doesn't work
try2 -> document.getElementById("data").text; //doesn't work
if you are intelligent in javascript please give me answer that how to get content of script inside content
thanks in advance for your answer
my website is : http://www.bolo7.com/
The text property defined by the HTMLScriptElement interface is the text content of the script element. If the element uses a src attribute, it should not have any content so its text property will be an empty string.
In that case, you will need to access the src some other way, perhaps XMLHttpRequest will suit.
Note also that the id attribute for script elements is not valid for the DOCTYPE being used at the linked resource (and the document is invalid).
Something like this?
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
//some data here
function add1(x) {
return 1 + x;
}
</script>
<script type="text/javascript">
alert(document.getElementsByTagName("script")[0].innerHTML);
</script>
</head>
<body>
</body>
</html>
but RobG is right, only works for inline javascript.
