get multiline field val using jquery isn't working in presav

Hi,

 

I have an issue in chrome browser---when i editting any item in chrome the changes made to the controls are not reflected in the presave action but when form getting saved its reflected.In IE is working fine.what can be the issue.

 

Used below syntax for retrieving the value of multiline field in presave.

 

var getComments = $('textarea[title="ApproverComments"]').text();
