<script type=\"text/javascript\">
$.fn.silde = function() {
var position = function(element) {
var top = element.position().top, pos = element.css
(\"position\");
$(window).scroll(function() {
var scrolls = $(this).scrollTop();
if (scrolls > top) {
if (window.XMLHttpRequest) {
element.css({
position: \"fixed\",
top: 0,
left:1080,
\"margin-left\":\"0px\",

});
} else {
element.css({
top: scrolls,
\"margin-left\":\"20px\"
});
}
}else {
element.css({
position: pos,
top: top,
\"margin-left\":\"20px\"
});
}
});
};
return $(this).each(function() {
position($(this));

});
};
$(\"#ding\").silde();
