Jquery html grab + calling a controller action using javascript (ruby on rails)
- by Zind
Preface: I consider myself "slightly effective" in ruby on rails, and a complete novice in javascript. Also, yes, I have installed jQuery and associated plugins instead of the default Prototype library.
I am in a situation where I am pulling in a table from off-site in an iframe (which is taking care of all internal JS for me) such that when a part of the table is clicked, a td will gain the class "active." What I would like to do is take this info (I'm assuming I can get it in a string format), and pass it to a method (in my controller, I'm assuming) which will parse the html, pull out the pertinent info, and then call a creation method in the same controller with the parsed info, the end result being a new item in that table.
What I have so far is javascript which I believe is correct so far:
<script type="text/javascript">
var ImportInfo = function() {
var info = $('td.active').html();
// call controller action which parses the given string,
//checks for existence in database, and adds new row if needed
}
$("#Import").click(ImportInfo);
</script>
and, of course, a button with id="ImportLocation."
I have looked at this question: http://stackoverflow.com/questions/1334447/using-jquery-to-call-a-controller-action but am somewhat unsure as to how to call a controller action to pass the contents of the td as a string. Is this doable with the jQuery post method?
