in the process of learning javscript and jquery, went through pages of google but can't seem to get this working. Basically I'm trying to collect innerhtml of classes, jquery seems to be suggested than plain javascript, into a document.write.
Here's the code so far;
<div class="mbox">Block One</div>
<div class="mbox">Block Two</div>
<div class="mbox">Block Three</div>
<div class="mbox">Block Four</div>
<script>
var mvar = $('.mbox').html();
document.write(mvar);
</script>
With this, only the first class shows under document.write. How can I show it all together like Block OneBlock TwoBlock Three? My ultimate goal with this is to show them comma seperated like Block One, Block Two, Block Three, Block Four. Thanks, bunch of relevant questions come up but none seem to be this simple.

var somevar = "apple" $( .... select all elements with class == somevar ). show();
In jQuery, the class and ID selectors are the same as in CSS. If you want to select elements with a certain class, use a dot ( . ) and the class name. If you want to select elements with a certain ID, use the hash symbol ( # ) and the ID name.
One possible way is to use .map() method:
var all = $(".mbox").map(function() {
return this.innerHTML;
}).get();
console.log(all.join());

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:
var mvar = "";
$(".mbox").each(function() {
console.log($(this).html());
mvar += $(this).html();
});
console.log(mvar);
With the code in the question, you're only dealing interacting with the first of the four entries returned by that selector.
Code below as a fiddle: https://jsfiddle.net/c4nhpqgb/
I want to be overly clear that you have four items that matched that selector, so you need to deal with each explicitly. Using eq() is a little more explicit making this point than the answers using map, though map or each is what you'd probably use "in real life" (jquery docs for eq here).
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
</head>
<body>
<div class="mbox">Block One</div>
<div class="mbox">Block Two</div>
<div class="mbox">Block Three</div>
<div class="mbox">Block Four</div>
<div id="outige"></div>
<script>
// using the $ prefix to use the "jQuery wrapped var" convention
var i, $mvar = $('.mbox');
// convenience method to display unprocessed html on the same page
function logit( string )
{
var text = document.createTextNode( string );
$('#outige').append(text);
$('#outige').append("<br>");
}
logit($mvar.length);
for (i=0; i<$mvar.length; i++) {
logit($mvar.eq(i).html());
}
</script>
</body>
</html>
Output from logit calls (after the initial four div's display):
4
Block One
Block Two
Block Three
Block Four
