Creating email link with dynamically generated body with html5 & javascript

Question

Am trying to create a link to create an email to send information to the user, the body of which needs to be filled with data generated by a javascript function, and hope that someone can help.

Idealy, if I could substitute the 'body_blurb' below, with a string returned from a javascript function called at the time of clicking that'd be perfect.

<A HREF="mailto:[email protected]?subject=Data&body=body_blurb">e-mail data</a>

Appreciate your time

Solution 1

I just assigned an id to the link here, but you could create something more generic if you wanted. Once you have an onclick handler created you can access the url with href. Set this to whatever you want.

http://jsfiddle.net/f3ZZL/1

var link = document.getElementById('email');
link.onclick = function() {
    this.href = "mailto:[email protected]?subject=Data&body=";
    this.href += getBody();
};

function getBody() {
    return 'HelloWorld';
}

Solution 2

Here is the no-spam method

var link = document.getElementById('email');

link.onclick = function() {
    var name = "you";
    var domain = "yourdomain.com";
    var linker = "mailto:" + name + '@' + domain + "?subject=Data&body=";
    linker += getBody();
    link.setAttribute("href", linker);
};

function getBody() {
    return 'HelloWorld';
}

Hmmm, so you could use location.href = mailto: ...?

Perfect - exactly what I was after. By way of further explanation, I'm creating a simple engineering calculation number cruncher to be accssed via mobile browsers. The user would enter their variables, crunch the numbers and get an output. I'd like to be able to give them the option of sending themselves the data set of inputs & outputs.
