The following smooth scrolling script messes up my navigation in Safari (anchor tags don't work anymore). I'm a Javascript newbie, could anyone tell me how to detect Safari in this script and prevent it from executing when it detects Safari? Many thanks!
// JavaScript Document
$(document).ready(function() {
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
var targetOffset = $target.offset().top;
$(this).click(function(event) {
event.preventDefault();
$(scrollElem).animate({scrollTop: targetOffset}, 1300, function() { // scroll speed
location.hash = target;
});
});
}
}
});
// use the first element that is "scrollable"
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
return [];
}
});
请参阅: http : //api.jquery.com/jQuery.browser/ ,以检测浏览器并仅在非Safari浏览器时执行脚本
var isSafari = navigator.userAgent.indexOf("Safari") > -1 && navigator.userAgent.indexOf("Chrome") == -1;
if(!isSafari){
// do your magic
}
Perhaps this:
$(document).ready(function()
{
if (navigator.appVersion.match(/WebKit/) && !navigator.vendor.match(/Google/))
{
return;
}
//rest of your code
});
if you have any code outside the $(document).ready callback, you could kill the script by throwing an error, by writing this at the top of your script(s):
if (navigator.appVersion.match(/WebKit/) && !navigator.vendor.match(/Google/))
{
throw new Error('Safari not supported');
