我在运行 javascript(来自CSS Tricks Demos)时遇到了一个小问题,我收到“意外的输入结束”错误。这是代码。
function UpdateTableHeaders() {
$(".persist-area").each(function() {
var el = $(this),
offset = el.offset(),
scrollTop = $(window).scrollTop(),
floatingHeader = $(".floatingHeader", this)
if ((scrollTop > offset.top) && (scrollTop < offset.top + el.height())) {
floatingHeader.css({
"visibility": "visible"
});
} else {
floatingHeader.css({
"visibility": "hidden"
});
};
});
}
// DOM Ready
$(function() {
var clonedHeaderRow;
$(".persist-area").each(function() {
clonedHeaderRow = $(".persist-header", this);
clonedHeaderRow
.before(clonedHeaderRow.clone())
.css("width", clonedHeaderRow.width())
.addClass("floatingHeader");
});
$(window)
.scroll(UpdateTableHeaders)
.trigger("scroll");
有人可以帮帮我吗?
