javascript - Raphael set.mouseover() - 停止事件传播

Question

我正在使用 Raphael.js 制作美国 map ，您可以在此处查看:http://www.motionflashdesigns.com/usabbr/

我已经开始使用 set() 添加状态缩写，以便状态路径及其文本缩写位于同一个对象中。

我在整个集合对象上添加了一个鼠标悬停事件处理程序，但是子文本也注册了鼠标悬停事件，这实际上导致了集合上的鼠标悬停，有人知道如何停止集合子对象上的事件传播吗？

在 jquery 中，我会使用 mouseenter 或 event.stopPropagation，但 Raphael 似乎都不支持这些。

这是 JS:

$(function () {

    var stateNames = new Array();
    var stateURLs = new Array();
    var stateModes = new Array();
    var stateColors = new Array();
    var stateOverColors = new Array();
    var stateClickedColors = new Array();
    var stateText = new Array();

    var offColor;
    var strokeColor;
    var mapWidth;
    var mapHeight;
    var useSideText;
    var textAreaWidth;
    var textAreaPadding;

    var mouseX = 0;
    var mouseY = 0;
    var current = null;

    // Detect if the browser is IE.
    var IE = $.browser.msie ? true : false;

    $.ajax({
        type: 'GET',
        url: 'xml/usaMapSettings.xml',
        dataType: $.browser.msie ? 'text' : 'xml',
        success: function (data) {

            var xml;
            if ($.browser.msie) {
                xml = new ActiveXObject('Microsoft.XMLDOM');
                xml.async = false;
                xml.loadXML(data);
            } else {
                xml = data;
            }

            var $xml = $(xml);

            offColor = '#' + $xml.find('mapSettings').attr('offColor');
            strokeColor = '#' + $xml.find('mapSettings').attr('strokeColor');
            mapWidth = $xml.find('mapSettings').attr('mapWidth');
            mapHeight = $xml.find('mapSettings').attr('mapHeight');
            useSideText = $xml.find('mapSettings').attr('useSideText');
            textAreaWidth = $xml.find('mapSettings').attr('textAreaWidth');
            textAreaPadding = $xml.find('mapSettings').attr('textAreaPadding');

            if (useSideText == 'true') {
                $("#text").css({
                    'width': (parseFloat(textAreaWidth) - parseFloat(textAreaPadding * 2)) + 'px',
                    'height': (parseFloat(mapHeight) - parseFloat(textAreaPadding * 2)) + 'px',
                    'display': 'inline',
                    'float': 'right',
                    'padding': textAreaPadding + 'px'
                });

                $('#text').html($xml.find('defaultSideText').text());
            }

            //Parse xml
            $xml.find('stateData').each(function (i) {

                var $node = $(this);

                stateText.push($node.text());
                stateNames.push($node.attr('stateName'));
                stateURLs.push($node.attr('url'));
                stateModes.push($node.attr('stateMode'));
                stateColors.push('#' + $node.attr('initialStateColor'));
                stateOverColors.push('#' + $node.attr('stateOverColor'));
                stateClickedColors.push('#' + $node.attr('stateSelectedColor'));
            });

            createMap();
        }
    });

您应该使用 mouseenter 和 mouseleave 事件，而不是 mouseover 和 mouseout 事件。
