Here is the code:
<span class='maincaptionsmall'>
Test
</span>
For some reasons of ajax and jquery codes in my page, I can't use HREF as Link, I mean, I can't use something like this following code:
<span class='maincaptionsmall'>Test</span>
So, How can i use jquery to get this css element maincaptionsmall and it will set it to href link ?
Even I can't use <div> too, I should use everything as <span> Please give me an example that how to use jquery to set css element as href link.
Thanks in advance
For getting .maincaptionsmall this DOM using jQuery use below code,
$('.maincaptionsmall')
and for wrapping innerText you can use wrapInner
$('.maincaptionsmall').wrapInner('');
Live Demo
Edit
You need to wrap code inside document.ready and also your document is not properly structured.
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() // you are missing this
{
$('.maincaptionsmall').wrapInner('');
});
</script>
</head>
<body>
<span class='maincaptionsmall'>Test</span>
</body>
</html>

I am trying to run a javascript inside of a div tag because i have heard its possible but for some reason the code does nothing.
<!DOCTYPE html>
<html>
<body>
<title>XDSITE</title>
<br>
<br>
<div id=mycode style="BACKGROUND:
url('javascript:eval(window.alert("sometext"))'"></div>
</body>
</html>
You have some problems in your HTML it is not valid, you can't run JavaScript from a style attribute.
You can run Javascript from within a <script> tag which really is the best way to do it.
<script>
document.getElementById("demo").innerHTML = "Hello JavaScript!";
</script>
Alternatively there are some HTML elements that allow you to execute it on some events, like onchange, onclick etc.
<select onchange="myFunction()">
<button onclick="myFunction()">Click me</button>
https://www.w3schools.com/ is a great resource for learning more about each html element, and also JavaScript as a whole.
Good luck
can you please tell here which java script framework is you are using? you can achieve this by using and template java script framework like Angular, React...
If u dont want to use any framework than you need to write pure javascript or jquery code for assigning the background css prop.
for entire body,
document.body.style.backgroundImage = "url('img_tree.png')";
for div,
document.getElementById("mycode").style.backgroundImage = "url('img_tree.png')";
<!-- U have to give event inside expression like onclick ,mouseup Click that text -->
<div id=mycode onclick="alert('Hi ....sometext')">THARA
</div>
<!DOCTYPE html> <html> <body> <title>XDSITE</title> <br> <br> <div id=mycode style="BACKGROUND: url('javascript:eval(window.alert("sometext"))'"></div> </body> </html>
Answer :
Open script in footer
<script>
$( "#mycode" ).click(function() {
alert( "Hai" );
});
</script>
I hope its working for you ...
You can target HTML tag using getElementById() and then apply custom style like this
document.getElementById("Mydiv").style.backgroundColor="#0000"
or apply a bunch of styles like this
var dev = document.getElementById("Mydiv");
dev.style.backgroundColor="#0000";
dev.style.fontSize="..";
dev.style.backgroundImage="..";
You can run your function using "onerror" event. And also you must do some error in that case. For eg.
<img src="someFakeSrc" onerror='javascript:eval(window.alert("sometext"))'>
HTML doesn't see a src of picture then run a 'onerror' event.
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.
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'
So is it possible to snag the entire content of a page in its current state. For example, if interacting with a page, via jquery, I've modified the document by either inserting content, or by adding or removing class names. Is it possible to get the markup of this document in its current form from starting html tag to html tag?
Something like
document.documentElement.innerHTML
This doesn't include the <html> opening and closing tags
Can't you just get the root object in the DOM and call innerHTML to get it all?
just call $('html').html() using jquery to get page source.
<html>
<head>
<title>Just a test</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$('#showContent').click(function(event){
event.preventDefault();
var pageSource = '<html>' + $('html').html() +'</html>';
alert(pageSource);
});
});
</script>
</head>
<body>
<a href="#" id="showContent" >show content</a>
</body>
</html>
