動力學獲得點擊

我只是想設置每個形狀的單擊事件特定形狀ID，我希望能夠以顯示給我哪方是基於了他們的身份證。動力學獲得點擊

var stage = new Kinetic.Stage({ 
container: 'container', 
    width: 700, 
    height: 700, 
}); 


var squareLayer; 
var boardBlankArray; 

function drawBoard() { 
    var squareLayer = new Kinetic.Layer(); 
    var initialSquares = 64; 
    var squareX = 20; 
    var squareY = 20; 
    boardBlankArray = []; 

for (i = 0; i < initialSquares; i++) { 
    var square = new Kinetic.Rect({ 
     x: squareX, 
     y: squareY, 
     width: 50, 
     height: 50, 
     fill: "blue", 
     stroke: "black", 
     strokeWidth: 2, 
     id: "squares" + i 
    }); 

    squareX += 60; //update squares X (horizontal) position 
    if (squareX > 450) { 
     squareX = 20; 
     squareY += 60; 
    } 


    boardBlankArray[i] = square; 

    squareLayer.add(boardBlankArray[i]); 

    boardBlankArray[i].on("click", function() { 
     alert(boardBlankArray[i].getId()); 
    }); 
} 
    stage.add(squareLayer); 
} 


drawBoard();

我做了小提琴和出於某種原因跟它boardBlankArray是不確定的，但它顯然是。另外，當我在我的計算機上進行本地操作時，我不會收到該錯誤。相反，它只是提醒所有廣場的相同ID。

任何幫助將不勝感激。

嘗試this.attrs.id代替boardBlankArray [I] .getId（）爲形狀標識

非常簡單。我應該記住'this'，也可以發現它也適用於this.getId（）。謝謝！ – j0hnstew

試試這個，而不是點擊一下，用ev來獲取事件的形狀對象t.shape並在該對象上使用getId（）

boardBlankArray[i].on("click", function(evt) { 
var node=evt.shape; 
      alert(node.getId()); 
     });
