Jquery judges Javascript in IE6 Browser

The jquery blog still has a 3D map, and Firefox Google IE has been done, and the rest is still ie6.
To ensure quick launch, you have to select CSS hack
Because some Div widths are determined based on the screen width Js.
Dumb, even CSS hack is not neat.
The hateful Internet Explorer 6 has spent a whole morning tossing you.
This is not a general sense of nausea. You cannot use JavaScript to give IE6 a judgment.
Jquery API
$. Available value of the browser kernel identifier: safari opera MSIE Mozilla
$. Typical browser rendering engine version: Internet Explorer: 6.0, 7.0 Mozilla/Firefox/flock/Camino: 1.7.12, 1.8.1.3 Opera: 9.20 Safari/WebKit: 312.8, 418.9
$. Support. style is a set of attributes used to display the characteristics and bugs of different browsers.
The final intersection result is that the evil is quickly pushed to IE6.
Code
If ($. browser. MSIE & ($. browser. Version = "6.0 ″)&&! $. Support. Style ){
// Code
}
