Question

我正在处理一项任务，即通过kinetic js文件在点击事件中创建，拖动，调整多种形状。

几乎我已经完成了所有的事情，当我创建多个形状时我想要的问题即将到来之后当我在那个时候调整大小时，第一个形状只调整大小它没有调整多个形状的大小

所以我想调整鼠标箭头目标形状。

这是我的代码，

//This update shows the image size minimum and maximum
function update(group, activeAnchor) {
    var topLeft = group.get(".topLeft")[0];
    var topRight = group.get(".topRight")[0];
    var bottomRight = group.get(".bottomRight")[0];
    var bottomLeft = group.get(".bottomLeft")[0];
    var rect = group.get(".rect")[0];
    // update anchor positions
     switch (activeAnchor.getName()) {
         case "topLeft":
             topRight.attrs.y = activeAnchor.attrs.y;
             bottomLeft.attrs.x = activeAnchor.attrs.x;
             if(topLeft.attrs.x >= topRight.attrs.x)
             {return;}
             break;
         case "topRight":
             topLeft.attrs.y = activeAnchor.attrs.y;
             bottomRight.attrs.x = activeAnchor.attrs.x;
             if(topRight.attrs.x <= topLeft.attrs.x)
             {return;}
             break;
         case "bottomRight":
             bottomLeft.attrs.y = activeAnchor.attrs.y;
             topRight.attrs.x = activeAnchor.attrs.x;
             if(bottomLeft.attrs.x >= topRight.attrs.x)
             {return;}                                                         
             break;
         case "bottomLeft":
             bottomRight.attrs.y = activeAnchor.attrs.y;
             topLeft.attrs.x = activeAnchor.attrs.x;
             if(bottomRight.attrs.x <= topLeft.attrs.x)
             {return;}                                                                                             
             break;
     }

     rect.setPosition(topLeft.attrs.x, topLeft.attrs.y);
     rect.setSize(topRight.attrs.x - topLeft.attrs.x, bottomLeft.attrs.y - topLeft.attrs.y);
}


            //AddAnchor gives set the corner of the image
function addAnchor(group, x, y, name) {

                 var stage = group.getStage();
                 var layer = group.getLayer();

                 var anchor = new Kinetic.Circle({
                     x: x,
                     y: y,  
                     stroke: "transparent",
                     fill: "transparent",
                     strokeWidth: 5,
                     radius: 35,
                     name: name,
                     draggable: true,
                     dragBounds: {
             top: 10,
             right: stage.getWidth() -10,
             bottom: 450,
             left: 10
           }
                 });

                 anchor.on("dragmove", function() {
                     update(group, this);
                     console.log(this);
                     layer.draw();
                 });
                 anchor.on("mousedown", function() {
                     group.draggable(false);
                     this.moveToTop();
                 });
                 anchor.on("dragend", function() {
                     group.draggable(true);
                     layer.draw();

                 // add hover styling

                     var layer = this.getLayer();
                     document.body.style.cursor = "move";
                     this.setStrokeWidth(4);
                       this.setStroke("black");
                     fill: "red";
                     strokeWidth: 2;
                     radius: 8;
                      layer.draw();
                 });

                 anchor.on("mouseout", function() {
                     var layer = this.getLayer();
                     document.body.style.cursor = "default";
                     this.setStrokeWidth(2);
                      this.setStroke("transparent");
                     layer.draw();
                 });
                    group.add(anchor);
             }

function addRect()
{
    var rectShape = new Kinetic.Rect({
                    width: 300,
                    height:120,
                    strokeWidth: 2,
                     stroke: "red",
                     name: "rect"
      });

rectShape.on("mouseover", function() {
                     var layer = this.getLayer();
                     document.body.style.cursor = "cursor";
                     this.setStrokeWidth(0);
                     this.setStroke("pink");
                     writeMessage(messageLayer, "Double Click To Remove");
                     layer.draw();                   
                 });

writeMessage(messageLayer, " ");
                      layer.draw();
                 });                 
var messageLayer = new Kinetic.Layer();
        stage.add(messageLayer);
                darthVaderGroup.add(rectShape);
                addAnchor(darthVaderGroup, 0, 0, "topLeft");
                addAnchor(darthVaderGroup, 300, 0, "topRight");
                addAnchor(darthVaderGroup, 300, 120, "bottomRight");
                addAnchor(darthVaderGroup, 0, 120, "bottomLeft");
                addAnchor(darthVaderGroup, 0, 120, "bottomLeft");

      rectShape.on("dblclick", function(){
                var shapesLayer=this.getLayer();
 darthVaderGroup.remove(rectShape);
 shapesLayer.clear();
 shapesLayer.draw();
   });


}

    //This click function is for create rectangle shape
$("#textsubmitShape").live("click",function(){
addRect();
});

您想要更改更新功能中的rect索引即var rect = group.get（“。rect”）[0]; 0显示第一个形状，这就是它仅调整第一个形状的原因。但是，我们如何根据目标形状改变该指数，我也不知道。

使用运动文件调整目标形状的大小
