我正在尝试做的事情：
当用户将鼠标悬停在图像上时，右上角应出现一个小 x（图像）。如果用户点击这个小 x，图像应该被删除，当用户鼠标移出时，小 x 应该消失。我尝试了几件事：
html结构是一个带有li和一个图像的ul
Javascript：
//On all the li's in the ul
$("li",$flickrKeyUlPreview).mouseover(addExternalImage);
var addExternalImage = function(){
//Get the offset of the image the user is hovering over
var offset = $(this).offset();
//Move the little x button to the image
$flickrDetailButton.offset(offset);
//Set it visible
$flickrDetailButton.css("visibility","visible");
//Bind the event for the mouseout
$flickrDetailButton.mouseout(removeExternalButton);
};
var removeExternalButton = function(){
//Hide the little x
$flickrDetailButton.css("visibility","hidden");
};
这不起作用的原因：当用户将鼠标悬停在小图像上时，会触发鼠标悬停。
我也试过：
$("li",$flickrKeyUlPreview).mouseover(addExternalImage);
var addExternalImage = function(){
$(this).unbind('mouseover');
var emptyObject = {};
$(this).append($.TemplateRenderer($flickrDetailButton,emptyObject));
$flickrDetailButton = $('#flickr_detail_button',rootel);
$(this).mouseout(removeExternalButton);
};
var removeExternalButton = function(){
$(this).unbind('mouseout');
$flickrDetailButton = $('#flickr_detail_button',rootel);
if ($($flickrDetailButton, $(this))) {
$($flickrDetailButton, $(this)).remove();
}
$(this).mouseover(addDelBtn);
};
This doesn't work that well, the little x starts flickering.
也试过这个：
$("li",$flickrKeyUlPreview).mouseenter(addExternalImage);
var removeExternalButton = function(){
$flickrDetailButton = $('#flickr_detail_button', rootel);
if ($($flickrDetailButton, $(this))) {
$($flickrDetailButton, $(this)).remove();
}
$(this).mouseenter(addExternalImage);
};
var addExternalImage = function(){
var emptyObject = {};
$(this).append($.TemplateRenderer($flickrDetailButtonTemplate,emptyObject));
$flickrDetailButton = $('#flickr_detail_button',rootel);
$(this).mouseout(removeExternalButton);
$flickrDetailButton.mouseleave(removeExternalButton);
};
这给出了相同的效果，它仍然在闪烁
有没有人有另一个想法如何做到这一点（不需要特定的代码，概念也很受欢迎；））？
