How do I create a link using javascript?


I have a string for a title and a string for a link. I'm not sure how to put the two together to create a link on a page using Javascript. Any help is appreciated.

EDIT1: Adding more detail to the question. The reason I'm trying to figure this out is because I have an RSS feed and have a list of titles ands URLs. I would like to link the titles to the URL to make the page useful.

EDIT2: I am using jQuery but am completely new to it and wasn't aware it could help in this situation.

With JavaScript

  1. var a = document.createElement('a');
    a.setAttribute('href',desiredLink);
    a.innerHTML = desiredText;
    // apend the anchor to the body
    // of course you can append it almost to any other dom element
    document.getElementsByTagName('body')[0].appendChild(a);
    
  2. document.getElementsByTagName('body')[0].innerHTML += '<a href="'+desiredLink+'">'+desiredText+'</a>';
    

    or, as suggested by @travis :

    document.getElementsByTagName('body')[0].innerHTML += desiredText.link(desiredLink);
    
  3. <script type="text/javascript">
    //note that this case can be used only inside the "body" element
    document.write('<a href="'+desiredLink+'">'+desiredText+'</a>');
    </script>
    

With JQuery

  1. $('<a href="'+desiredLink+'">'+desiredText+'</a>').appendTo($('body'));
    
  2. $('body').append($('<a href="'+desiredLink+'">'+desiredText+'</a>'));
    
  3. var a = $('<a />');
    a.attr('href',desiredLink);
    a.text(desiredText);
    $('body').append(a);
    

In all the above examples you can append the anchor to any element, not just to the 'body', and desiredLink is a variable that holds the address that your anchor element points to, and desiredText is a variable that holds the text that will be displayed in the anchor element.


Create links using JavaScript:

<script language="javascript">
<!--
document.write("<a href=\"www.example.com\">");
document.write("Your Title");
document.write("</a>");
//-->
</script>

OR

<script type="text/javascript">
document.write('Your Title'.link('http://www.example.com'));
</script>

OR

<script type="text/javascript">
newlink = document.createElement('a');
newlink.innerHTML = 'Google';
newlink.setAttribute('title', 'Google');
newlink.setAttribute('href', 'http://google.com');
document.body.appendChild(newlink);
</script>

There are a couple of ways:

If you want to use raw Javascript (without a helper like JQuery), then you could do something like:

var link = "http://google.com";
var element = document.createElement("a");
element.setAttribute("href", link);
element.innerHTML = "your text";

// and append it to where you'd like it to go:
document.body.appendChild(element);

The other method is to write the link directly into the document:

document.write("<a href='" + link + "'>" + text + "</a>");

Dynamically create a hyperlink with raw JavaScript:

   var anchorElem = document.createElement('a');
   anchorElem.setAttribute("href", yourLink);
   anchorElem.innerHTML = yourLinkText;

   document.body.appendChild(anchorElem); // append your new link to the body

You paste this inside :

<A HREF = "index.html">Click here</A>


<html>
<head></head>
<body>
<script>

var a = document.createElement('a');
var linkText = document.createTextNode("my title text");
a.appendChild(linkText);
a.title = "my title text";
a.href = "http://example.com";
document.body.appendChild(a);

</script>
</body>
</html>

    <script>
      _$ = document.querySelector  .bind(document) ;

        var AppendLinkHere = _$("body") // <- put in here some CSS selector that'll be more to your needs
        var a   =  document.createElement( 'a' )
        a.text  = "Download example" 
        a.href  = "//bit\.do/DeezerDL"

        AppendLinkHere.appendChild( a )
        

     // a.title = 'Well well ... 
        a.setAttribute( 'title', 
                         'Well well that\'s a link'
                      );
    </script>

  1. The 'Anchor Object' has its own*(inherited)* properties for setting the link, its text. So just use them. .setAttribute is more general but you normally don't need it. a.title ="Blah" will do the same and is more clear! Well a situation that'll demand .setAttribute is this: var myAttrib = "title"; a.setAttribute( myAttrib , "Blah")

  2. Leave the protocol open. Instead of http://example.com/path consider to just use //example.com/path. Check if example.com can be accessed by http: as well as https: but 95 % of sites will work on both.

  3. OffTopic: That's not really relevant about creating links in JS but maybe good to know: Well sometimes like in the chromes dev-console you can use $("body") instead of document.querySelector("body") A _$ = document.querySelectorwill 'honor' your efforts with an Illegal invocation error the first time you use it. That's because the assignment just 'grabs' .querySelector (a ref to the class method). With .bind(... you'll also involve the context (here it's document) and you get an object method that'll work as you might expect it.
