Menu
I have this form http://jsfiddle.net/thiswolf/XDsSt/ with four identical inputs and buttons.The problem is,each section is updates its own unique data in the database so when updating,its important the submit button i click updates the database with the input from that section only.
My function is
$(document).ready(function() {
$(".xx").live('click', function(){
alert('clicked');
});
});
How do i make sure the button click is unique to that section?.

Use an ID value instead for each input button. This way, jQuery can identify it like so:
$('#button_tag');
HTML:
<html>
<head></head>
<body>
<section>
<input type="text" value="Town">
<input type="text" value="Mayor">
<input type="text" value="Highway">
<input id="btn1" type="submit" class="xx" value="Submit">
</section>
<section>
<input type="text" value="Town">
<input type="text" value="Mayor">
<input type="text" value="Highway">
<input id="btn2" type="submit" class="xx" value="Submit">
</section>
<section>
<input type="text" value="Town">
<input type="text" value="Mayor">
<input type="text" value="Highway">
<input id="btn3" type="submit" class="xx" value="Submit">
</section>
<section>
<input type="text" value="Town">
<input type="text" value="Mayor">
<input type="text" value="Highway">
<input id="btn4" type="submit" class="xx" value="Submit">
</section>
</body>
</html>
Javascript:
$(document).ready(function () {
$(".xx").live('click', function () {
alert('clicked ' + $(this).attr('id'));
});
});

Get the corresponding section that button belongs to . Then access the elements inside that. You may use the jQuery closest()/parent()(if only one layer of hierarchy of controls) function for that.
$(document).ready(function() {
$(".xx").live('click', function(e){
e.preventDefault(); //if you want to prevent normal form submit
var item=$(this);
var sectionClicked=item.closest("section");
//Let's alert the first text box
alert(sectionClicked.find("input").first().val());
//do whatever with the items belongs the current section
});
});

I recommend you to switch to jQuery on instead of live as it is deprecated.
