检测早期版本的ie，即使用less.js，然后使用过滤器？

Question

I have a function which applies gradients in less as :

.linearGradient(@begin: black, @end: white, @switch : 100%) {
  background: @begin;
  background: -webkit-gradient(linear, 0 0, 0 100%, from(@begin), color-stop(@switch, @end));
  background: -moz-linear-gradient(top, @begin, @end @switch);
  background: -o-linear-gradient(top, @begin, @end @switch);
  background: linear-gradient(top, @begin, @end @switch);
  filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=@top, endColorstr=@bottom,GradientType=0 ); /* IE6-9 */
}

I want to be able to test for a versions < IE10 and use filter else just use css3.

Edit: Additional questions Is there a way to test for browsers?

Answer 1

Don't bother making a test; IE10 doesn't support the filter property.
