raphael.js IE8 and Jquery

问题:

I am creating an anatomic man where the user can rollover muscles, the muscles are highlighted and when clicked they display the name of the muscle. Through a separate JQuery, I have a group of <dl>s that show and hide depending on the muscle group clicked. This works fine in IE9, and other modern browsers, but I am having an issue within IE8. IE8 only wants to use the code within the generated raphael.js. So I need to move the jquery into raphael…which I'm sure will be a more elegant way of doing this. However, I am unsure of how to proceed with this.

Here is my code:

paths.js

var paths = { 
neck: {
    name: 'neck',
    path: 'd="M412.294,73.035c0,0,7.661,28.869,9.406,31.78c1.746,2.911,4.657,2.911,9.896,2.911 s9.313-1.746,9.896-5.239c0.582-3.493,6.985-28.523,6.985-28.523s-2.963,2.599-6.232,5.984c-2.543,2.632-7.2,5.904-11.088,5.904 c-3.889,0-6.705-2.431-10.367-5.04C418.063,78.868,418.08,79.22,412.294,73.035z"',
},
pecks: {

},
}

init.js

$(function(){

var r = Raphael('man', 500, 573),
    attributes = {
        fill: '#204ad3',
        opacity: '0.0',
        'stroke-linejoin': 'round'

    },
arr = new Array();

var id = 0;

for (var muscles in paths) {

    var obj = r.path(paths[muscles].path);

    obj.attr(attributes);

    obj.node.id = "muscle" + id;
    id++

    arr[obj.id] = muscles;

    obj
    .hover(function(){
        this.animate({
            fill: '#204ad3',
            opacity: '0.3'
        }, 300);
    }, function(){
        this.animate({
            fill: attributes.fill,
            opacity: attributes.opacity
        }, 300);
    })

    .click(function(){
        document.location.hash = arr[this.id];

        var point = this.getBBox(0);

        $('#man').next('.point').remove();

        $('#man').after($('<div />').addClass('point'));

        $('.point')
        .html(paths[arr[this.id]].name)
        .prepend($('<a />').attr('href', '#').addClass('close').text('Close'))
        .css({
            left: point.x+(point.width/2)-80,
            top: point.y+(point.height/2)-20
        })
        .fadeIn();

    });

    $('.point').find('.close').live('click', function(){
        var t = $(this),
            parent = t.parent('.point');

        parent.fadeOut(function(){
            parent.remove();
        });
        return false;
    });
}   

}); 

In the init.js code there is a click(function() that generates a popup for the muscle group. How could I add a code that would allow other jquery to happen depending on the path the user clicks? Something like:

$("dl").hide().delay(100);$('.tag-pathnamehere').show();

where 'pathnamehere' part of the class would change depending on the path clicked.

I believe this line adds the path name to the popup:

(paths[arr[this.id]].name)

I would like to somehow change the 'pathnamehere' part of the class to the path clicked.

I hope this is clear and any help would be much appreciated.

回答1:

Assuming that the dl elements are already created (are they?), I guess you could do something like:

arr = new Array();
tags = new Array();

...
arr[obj.id] = muscles;

tags[obj.id] = ".tag-" + paths[muscles].name;

and then in the click handler

$(tags[this.id]).show();
