该功能在Windows的Safari浏览器中不起作用

Question

While this syntax works on all other browser, safari on windows throws an error

$("#kibana").contents().find('.navbar-nav')[0].remove();

The error is

TypeError: 'undefined' is not a function 

The element does exist. I checked using the debugger.

Why is this happening?

Answer 1

When you use [] on a jQuery object, you are retrieving the underlying DOM node. .remove isn't fully cross-browser compatible on native DOM elements.

Instead, you can use .eq to retrieve the element while still having it wrapped in jQuery. That way you can use the cross-browser comptabile .remove method:

$("#kibana").contents().find('.navbar-nav').eq(0).remove();
