jquery - 使用jquery或纯javascript为不同浏览器动态添加不同版本的css

Question

如您所知，为了使 css3 适用于不同的浏览器，必须使用不同版本的 css。例如，要使背景渐变成为可能，这些是所需的 css。

background: rgb(30,87,153); /* Old browsers */
background: -moz-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%, rgba(41,137,216,1) 50%, rgba(32,124,202,1) 51%, rgba(125,185,232,1) 100%); /* FF3.6+ */
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(30,87,153,1)), color-stop(50%,rgba(41,137,216,1)), color-stop(51%,rgba(32,124,202,1)), color-stop(100%,rgba(125,185,232,1))); /* Chrome,Safari4+ */
background: -webkit-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* Opera 12+ */
background: -ms-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* IE10+ */
background: radial-gradient(ellipse at center, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#7db9e8',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */

我的问题是，如何将这些 css 动态添加到 div 中？我尝试使用 css(map) 方法，但它不起作用。最后一个 css 将覆盖前一个。最糟糕的是，css(map) 不适用于过滤器。

这不是很漂亮，但它似乎有效:

$div.attr('style',"background: rgb(30,87,153); background: -moz-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%, rgba(41,137,216,1) 50%, rgba(32,124,202,1) 51%, rgba(125,185,232,1) 100%); background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(30,87,153,1)), color-stop(50%,rgba(41,137,216,1)), color-stop(51%,rgba(32,124,202,1)), color-stop(100%,rgba(125,185,232,1)));  background: -webkit-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); background: -o-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); background: -ms-radial-gradient(center, ellipse cover, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); background: radial-gradient(ellipse at center, rgba(30,87,153,1) 0%,rgba(41,137,216,1) 50%,rgba(32,124,202,1) 51%,rgba(125,185,232,1) 100%); filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#7db9e8',GradientType=1 );");
