You will need to loop through it like an array. JavaScript doesn't have a foreach keyword, but it can do a "for in" :
<script type="text/javascript">
var obj = {
member1 : 'value1',
another : 'another2',
data3 : 'datavalue3'
}, i;
for (i in obj) {if (obj.hasOwnProperty(i)) {
document.write(i + ' = ' + obj[i] + '<br />');
}}
</script>
Output
member1 = value1
another = another2
data3 = datavalue3
Obviously you can build a better layout during the loop using html, assigning a title tag with the values could be a temporary solution as well.
Believe it or not, I'm much better at JavaScript than PHP
