大家好。今天我在做一个图片放大镜的jquery插件。类似于京东上那种商品图片的放大镜。

我发现我在image对象上绑定了mouseenter和mouseleave后，当鼠标在image上移动是会同时触发mouseenter和mouseleave，造成了闪烁。
可是我并不期望mouseenter, mouseleave被反复调用，甚至是同时发生。应该如何解决呢？尝试了网上的几种方法都不太可行。

多谢各位。

$.fn.magnify = function() {
    //var glassBox = options.glassBox || {};
    //var detailBox = options.detailBox || {};

    var glassBox = $('');

    glassBox.css({
        "width": this.width() / 2 + 'px',
        "height": this.height() /2 + 'px',
        "background-color": 'grey',
        "position": "absolute",
        "left" : '0px',
        "top": '0px',
        'opacity': '0.2',
        'display': 'none',
        'border': '1px solid blue',
        'z-index': 10

    });

    $(this).after(glassBox);
    //glassBox.hide();

    var detailBox = $('
');
    var detailImage = $('');
    
    detailBox.css({
        "width": this.width(),
        "height": this.height(),
        "display": 'none',
        "position": 'relative',
        "overflow": 'hidden'
        //"background-color": 'lime'
    });
    detailImage.css({
        "position": 'absolute'
    });
    detailImage.attr("src", this.attr("src"));
    detailBox.append(detailImage);
    this.after(detailBox);


    this.mouseenter(function(event){
        //event.stopPropagation();
        glassBox.get(0).style.display = 'block';
        detailBox.get(0).style.display = 'block';
        
        

    });
    this.mouseleave(function(event){    
        //event.stopPropagation();
        if (event.relatedTarget !== "span") {
            glassBox.get(0).style.display = 'none';
        detailBox.get(0).style.display = 'none';
        }
        
    });

    this.mousemove(function(event) {
        /* Act on the event */
        var x = event.pageX - this.offsetLeft - glassBox.width() / 2;
        var y = event.pageY - this.offsetTop - glassBox.height() /2;
        if (x < 0 ) {
            x = 0;
        } else if ( x > this.offsetWidth - glassBox.width()) {
            x = this.offsetWidth - glassBox.width();
        }
        if (y < 0) {
            y = 0;
        } else if (y > this.offsetHeight - glassBox.height()) {
            y = this.offsetHeight - glassBox.height();
        }
        glassBox.css({
            left: x + 'px',
            top:  y + 'px'
        });

        detailImage.css({
        "left": -3.5 * (event.pageX - this.offsetLeft) + 'px',
        "top": -3.5 * (event.pageY - this.offsetTop) + 'px'
    });
    });
}

HTML如下：
