鼠标悬停 - 鼠标移出 - Javascript

Question

我想做什么：

当用户将鼠标悬停在图像上时，右上角应该会出现一个小 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。我已经尝试了几件事：

html结构是一个ul，里面有li和一张图片

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。

我也试过了：

$("li",$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);
    };

同样的效果，它还在闪烁

有没有人知道如何做到这一点（不需要特定的代码，概念也很受欢迎；））？

Answer 1

$('selector').hover(addExternalImage, removeExternalButton);

Answer 2

将mouseover 和mouseout 替换为mouseenter 和mouseleave。
