jquery attr() do not work in IE

问题

I use jquery to do some thing, and I use attr() method to get the id attribute, and it works well in Chrome and Firefox, but not in IE9 and Opera, some of the code is like:

parent = $(this).parents('.every_note');        
loan_id = parent.attr('id');

in the line

loan_id = parent.attr('id');

Opera said: Unhandled Error: 'parent.attr' is not a function, and in IE said: does not support attr() method or attribute.

But i can use this method if I test it in the browser's console , so anyone can tell me why？ thanks

回答1:

Sometimes IE does not like the "$" while "jQuery" does work for me. In older IEs there is another problem with global vars in combination with jQuery.

Try:

var parent = jQuery(this).parents('.every_note');        
var loan_id = parent.attr('id');

Use

parent = $(this).parents('.every_note');   
loan_id = $("+parent+").attr('id');
