raphael.js如何將id添加到路徑

Question

我剛開始使用Raphael.js，並且難以將一個id添加到路徑中。我已經閱讀了很多關於如何做的文章，但我認爲我的文件設置方式不允許我輕鬆地翻譯這些解決方案。

我有一個init.js文件和文件path.js

init.js

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

    }, 
arr = new Array(); 

for (var muscles in paths) { 

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

    obj.attr(attributes); 

    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')) 
     .prepend($('<img />').attr('src', 'flags/'+arr[this.id]+'.png')) 
     .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; 
    }); 
} 

path.js文件：

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"',

}, 
} 

生成SVG元件不具有一個ID，我也不知道如何在那裏得到一個。任何意見/幫助將不勝感激。

Answer 1

這將id屬性添加到SVG路徑元素：

var id = 0; 

for (var muscles in paths) { 

    var obj = r.path(paths[muscles].path); 
    obj.node.id = "muscles_or_whatever_you_want_" + id; 
    id++ 

    //.... 

Answer 2

它看起來像你試圖做的是彈出一個圖像和單擊路徑上方的關閉鏈接的div。問題在於，您將路徑對象的Raphael ID與paths陣列中的索引混淆在一起。你可能想消除arr完全通過一個封閉的索引傳遞到您的處理程序：

.click(function(index) { return function() { 
    document.location.hash = index; 

    var point = this.getBBox(0); 

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

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

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

}; }(muscles)); 

Answer 3

一個ID添加到SVG元素.... paper.path(path data).node.id = 'pathIdString';。測試...試試alert(document.getElementById("pathIdString").id);。應該返回ID
