jquery - 工具提示指针向下显示到超链接的左侧

Question

我使用了 tipsy tooltip 插件。我想在链接左侧显示工具提示。我使用了以下代码。
工具提示正确指向其左侧的链接。但问题是它的指针没有指向链接。它指向下方。如何解决这个问题？

JS/HTML

$('.tip').tipsy({gravity: 'e'});

<a class='tip' href='index.php' title='test'>Test</a>

(function($) {
$.fn.tipsy = function(options) {

    options = $.extend({}, $.fn.tipsy.defaults, options);

    return this.each(function() {

        var opts = $.fn.tipsy.elementOptions(this, options);

        $(this).hover(function() {

            $.data(this, 'cancel.tipsy', true);

            var tip = $.data(this, 'active.tipsy');
            if (!tip) {
                tip = $('<div class="tipsy lefttip"><div class="tipsy-inner"/></div>');
                tip.css({position: 'absolute', zIndex: 100000});
                $.data(this, 'active.tipsy', tip);

            }

            if ($(this).attr('title') || typeof($(this).attr('original-title')) != 'string') {
                $(this).attr('original-title', $(this).attr('title') || '').removeAttr('title');
            }

            var title;
            if (typeof opts.title == 'string') {
                title = $(this).attr(opts.title == 'title' ? 'original-title' : opts.title);
            } else if (typeof opts.title == 'function') {
                title = opts.title.call(this);
            }

            tip.find('.tipsy-inner')[opts.html ? 'html' : 'text'](title || opts.fallback);

            var pos = $.extend({}, $(this).offset(), {width: this.offsetWidth, height: this.offsetHeight});
            tip.get(0).className = 'tipsy'; // reset classname in case of dynamic gravity
            tip.remove().css({top: 0, left: 0, visibility: 'hidden', display: 'block'}).appendTo(document.body);
            var actualWidth = tip[0].offsetWidth, actualHeight = tip[0].offsetHeight;
            var gravity = (typeof opts.gravity == 'function') ? opts.gravity.call(this) : opts.gravity;

            switch (gravity.charAt(0)) {
                case 'n':
                    tip.css({top: pos.top + pos.height, left: pos.left + pos.width / 2 - actualWidth / 2}).addClass('tipsy-north');
                    break;
                case 's': 
                    tip.css({top: pos.top - actualHeight, left: pos.left + pos.width / 2 - actualWidth / 2}).addClass('tipsy-south');
                    break;
                case 'e': 
                    tip.css({top: (pos.top + pos.height / 2 - actualHeight / 2)+5, left: pos.left - actualWidth}).addClass('tipsy-east');
                    break;
                case 'w':
                    tip.css({top: pos.top + pos.height / 2 - actualHeight / 2, left: pos.left + pos.width}).addClass('tipsy-west');
                    break;
            }

            if (opts.fade) {
                tip.css({opacity: 0, display: 'block', visibility: 'visible'}).animate({opacity: 0.8});
            } else {
                tip.css({visibility: 'visible'});
            }

        }, function() {
            $.data(this, 'cancel.tipsy', false);
            var self = this;
            setTimeout(function() {
                if ($.data(this, 'cancel.tipsy')) return;
                var tip = $.data(self, 'active.tipsy');
                if (opts.fade) {
                    tip.stop().fadeOut(function() { $(this).remove(); });
                } else {
                    //tip.remove();
                }
            }, 100);

        });

    });

};

// Overwrite this method to provide options on a per-element basis.
// For example, you could store the gravity in a 'tipsy-gravity' attribute:
// return $.extend({}, options, {gravity: $(ele).attr('tipsy-gravity') || 'n' });
// (remember - do not modify 'options' in place!)
$.fn.tipsy.elementOptions = function(ele, options) {
    return $.metadata ? $.extend({}, options, $(ele).metadata()) : options;
};

$.fn.tipsy.defaults = {
    fade: false,
    fallback: '',
    gravity: 'n',
    html: false,
    title: 'title'
};

$.fn.tipsy.autoNS = function() {
    return $(this).offset().top > ($(document).scrollTop() + $(window).height() / 2) ? 's' : 'n';
};

$.fn.tipsy.autoWE = function() {
    return $(this).offset().left > ($(document).scrollLeft() + $(window).width() / 2) ? 'e' : 'w';
};

})(jQuery);

CSS

.tipsy { 
    margin-top:-5px!important;
    padding: 5px; 
    font-size: 10px; 
    background-repeat: no-repeat;  
    background-image: url(../images/btn/tip.png)!important;

.tipsy-south {

Answer 1

问题很可能与您在 .tipsy 中使用的图像有关

我试过以下方法，效果很好:

.tipsy { 
    margin-top:-5px!important;
    padding: 5px; 
    font-size: 10px; 
    background-repeat: no-repeat;  
    background-image: url('http://www.laurafeld.com/2010-In-the-woods/Images/20px-TriangleArrow-Right.svg.png')!important;
    // above just an example image I grabbed from a quick search
}

HERE IS A DEMO

编辑:在看到您最近的编辑后，我了解到您想要动态生成该图像，因此我建议您从 中删除 background-image .tipsy 并为每个 .tipsy-east, .tipsy-west... 添加不同的图像，如下所示:

.tipsy-north { 
    background-position: top center; 
    background-image: url('/images/path/down_arrow.jpg')!important;
}
.tipsy-south { 
    background-position: bottom center; 
    background-image: url('/images/path/up_arrow.jpg')!important;
}
.tipsy-east { 
    background-position: right center; 
    background-image: url('/images/path/right_arrow.jpg')!important;
}
.tipsy-west { 
    background-position: left center; 
    background-image: url('/images/path/left_arrow.jpg')!important;
}

注意:我使用的图像不是真实图像，您必须为每个方向创建/抓取您的图像并添加它们。
