How to access session inside Jquery Example
//simple session get using user_key
$.session.get('user_key');
Output => "value"
// Clear all simple value in session
$.session.clear();
//simple session get using user_key "undefined"
$.session.get('user_key');
After Clear output => undefined
// Set a simple data value and call in like single line
$.session.set('user_key', 'value').get('user_key');
output => "value"
// Remove all the data particular user_key from session
$.session.remove('user_key');
//key get to data
$.session.get('some user_key');
After Remove output => undefined
