我写了一个带有覆盖的弹出窗口(与通常的图片显示器不同),用户点击该窗口,并且覆盖层覆盖了用于显示的大图片的屏幕.
问题是,当用户点击"关闭"时,我的功能会淡化图片并覆盖,然后将其删除.当我调用该.remove()函数时,浏览器会关注body标签并滚动到页面顶部.
我尝试通过捕获offset.topco-ords并将它们存储在用户点击的元素的属性中,以及弹出窗口关闭时和之后的方法来进行解决.remove()我已经调用了scrollTo()函数,我使用该函数返回正确的滚动位置(由于某种原因,它会过冲并将元素滚动到顶部).
/*creating the popup layer and picture*/
function newsPopup(obj){
/***PART ZERO - get the timestamp value of this ***/
var itemID = $(obj).attr('itemID');
var storyNumber = $(obj).attr('storyNumber');
/*adding the identifier for later*/
var offset = $(obj).offset();
var roundedOff = Math.round(offset.top);
$(obj).attr('scrollMeBack', roundedOff);
/*** the script then continues to create an overlay and picture popup
}
/*function to remove popup*/
function overlayRemove(){
//first fade out the cover and the container
$("#NEWS_overlay").fadeOut();
$("#NEWS_centeringContainer").fadeOut();
//then remove it from the page completely
setTimeout('$("#NEWS_overlay").remove();$("#NEWS_centeringContainer").remove();',400);
/*value to scroll the element back to*/
var scrollBack = $('[SpringCMSscrollMeBack]').attr('SpringCMSscrollMeBack');
setTimeout('$(window).scrollTop('+scrollBack+')',401); /*notes the 1 millisecond delay here to mean the scroll ahppen after the item has been removed.*/
$('[scrollMeBack]').removeAttr('scrollMeBack');
}

为什么.remove()函数会导致跳转到页面顶部?即使scrollTo周围的工作看起来很邋of,因为东西逐渐淡出,但跳到屏幕的顶部,然后回到有问题的元素.
