You can use
alert(myarray.join())
to alert your array's values
You should use a associative array instead of an array, so that you can look up the data based on the name as a string instead of trying to find the variable. All objects in Javascript are associative arrays, so just put the data in an object.
Also:
- Create the
mygraphs
array inside the event handler, otherwise it can not shrink when you uncheck options. - Catch the click on the checkboxes inside the form, not on the form itself.
- Put a
label
tag around the checkbox and it's label, that way the label is also clickable. - You don't need an index variable to put values in the
mygraphs
array, just use thepush
method to add items to it.

Javascript:
$(function() {
Comment = [['2011-01-29',7695],['2011-02-02',19805]];
WallPost = [['2011-01-29',11115],['2011-02-02',8680]];
Likes = [['2011-01-29',5405],['2011-02-02',10930]];
var seriesre = {
'Comment': Comment,
'WallPost': WallPost,
'Likes': Likes
};
$("#testCheck :checkbox").click(function() {
var mygraphs = [];
$("#testCheck :checked").each(function() {
mygraphs.push(seriesre[$(this).val()]);
});
alert("["+mygraphs+"]");
});
});
HTML:
<div class="activity">
<form method="POST" id="testCheck" name="myform">
<label>
Likes
<input type="checkbox" value="Likes" name="box2">
</label>
<label>
Comments
<input type="checkbox" value="Comment" name="box3">
</label>
<label>
Wall Post
<input type="checkbox" value="WallPost" name="box4">
</label>
</form>
</div>
I understand that you want to alert the selected values when clicking anywhere on the form? If that's true correct code with minimal changes to your existing code will be:
var mygraphs = [];
$("#testCheck").click(function() {
$("#testCheck :checked").each(function() {
mygraphs.push($(this).val());
});
alert("Selected values are: " + mygraphs.join(", "));
});
You can try this.
alert($("#testCheck :checked")
.map( function(i, field) { return field.value}
).get());
