jQuery check if element exist

To check the length of the selector, if it returns you something then the element exists else not exist.

Use:

$('#element_id').length

if( $('#selector').length )         // use this if you are using id to check
{
     // it exists
}


if( $('.selector').length )         // use this if you are using class to check
{
     // it exists
}
