我试图这样做,当点击并打开手风琴面板时,它将移动到顶部,这样用户就不必向下滚动来查看内容。 这是我到目前为止所做的,但我尝试的任何东西似乎都无法工作,当我添加并激活功能时,整个手风琴功能都会停止工作。任何帮助是极大的赞赏。感谢。
$(function () {
$(".accordion").accordion({
collapsible: true,
active: false,
heightStyle: "content",
animate: 150,
//This makes it possible for multiple panels to be open at the same time
beforeActivate: function(event, ui) {
// The accordion believes a panel is being opened
if (ui.newHeader[0]) {
var currHeader = ui.newHeader;
var currContent = currHeader.next('.ui-accordion-content');
// The accordion believes a panel is being closed
} else {
var currHeader = ui.oldHeader;
var currContent = currHeader.next('.ui-accordion-content');
}
// Since we've changed the default behavior, this detects the actual status
var isPanelSelected = currHeader.attr('aria-selected') == 'true';
// Toggle the panel's header
currHeader.toggleClass('ui-corner-all',isPanelSelected).toggleClass('accordion-header-active ui-state-active ui-corner-top',! isPanelSelected).attr('aria-selected',((!isPanelSelected).toString()));
// Toggle the panel's icon
currHeader.children('.ui-icon').toggleClass('ui-icon-triangle-1-e',isPanelSelected).toggleClass('ui-icon-triangle-1-s',!isPanelSelected);
// Toggle the panel's content
currContent.toggleClass('accordion-content-active',!isPanelSelected)
if (isPanelSelected) { currContent.slideUp(); } else { currContent.slideDown(); }
return false; // Cancels the default action
}
});

这是我能够做的事情,使用stackoverflow中的多篇文章作为资源。我想出了一个简单的javascript函数,它使用jquery animate滚动到页面上任何元素的顶部。我叫它totop():
function totop(element) {
offset = element.offset();
$("html").animate({scrollTop:offset.top},500);
}
然后在文档就绪函数中,我定义一个事件来执行该函数,当点击手风琴上的面板(由ID accord-1标识)时:
$("#accord-1").on("accordionactivate",function(event,ui) {
totop(ui.newHeader);
});
这就像我的客户想要的那样。我在多个页面上使用它。这是一个简单的示例页面:
