jQuery gotchas

1. Playing with checkboxes:
To get all the checked checkboxes from a group use :
$("input.selectArticleCheckBox:checked");

2. To hide multiple elements in a screen with the same name use class instead of id:
$('tr.filterSection').show();
This shows all elements with class filterSection in a tr

3. Iterating through an array:
       $.each(
                    articles,
                    function( intIndex, obj ){                 
                        alert(obj.value);
                    }
         );

4. Check if element is visible: $('.classMessage').is(":visible")

5. Email validation using regex:
var regexEmail= /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z0-9]{2,4})$/;                          
if(!regexEmail.test(currentFieldValue)) { }

6. Manipulating select fields
$('#selectList').val();
$('#selectList :selected').text();

7. Debugging jquery on stupid IE

//global catch all
function handleError(e)

{

alert(’An error has occurred!\n’+e);

return true;

}

window.onerror = handleError;
Use stacktrace.js as a life saviour : stactrace.js
