KineticJs-如何在调整舞台图层大小后更新多个图像的x和y位置

由于我是KineticJs的新手,所以我尝试使用Kinectic js在不同的x和y上绘制多个图像。现在我想调整舞台图层或画布的大小。我已经通过使用下面给出的代码

完成了这项工作
  window.onresize = function (event) {

                                stage.setWidth(($('#tab' + tabId).innerWidth() / 100) * 80);
                                var _images = layer.getChildren();

                                for (var i = 0; i < _images.length; i++) {
                                    if (typeof _images[i].getId() != 'undefined') {
                                        //alert(stage.getScale().x);
                                        _images[i].setX(_images[i].getX() * stage.getScale().x);
                                        layer.draw();
                                    }
                                }
                            }

但现在问题是正在定义,现在如果浏览器调整大小而不是调整舞台大小但是前缀x和y上的图像是固定的。我想将它们固定在调整舞台图层或画布大小的位置。这是在调整大小之前和调整大小之后图像的链接。beforeresizeafterResize

以下是我的完整代码: -

$("#tabs li").each(function () {
            $(this).live("click", function () {
                clearInterval(_timer);
                var tabname = $(this).find("a").attr('name');
                tabname = $.trim(tabname.replace("#tab", ""));
                var tabId = $(this).find("a").attr('href');
                tabId = $.trim(tabId.replace("#", ""));
                $.ajax({
                    url: "/Home/GetTabsDetail",

                            //  500)

                        }

                        alert('error');
                    }
                });
            });
        });

我希望在调整大小之前将图标保持在原来的位置。我已经尝试过但无法得到正确的解决方案来完成这项工作。

如何更新图像的x,y位置?任何建议将不胜感激。

谢谢你的到来。

在window.resize中,您将通过缩放系数更改舞台宽度。

保存该比例因子。

然后将图像的“x”坐标乘以该缩放系数。

您可以像这样重置图像的“x”位置:

yourImage.setX( yourImage.getX() * scalingFactor );

layer.draw();

在上面提到的window.onresize代码中。代码已经修改,如下: -

 window.onresize = function (event) {

                                _orignalWidth = stage.getWidth();
                                var _orignalHeight = stage.getHeight();
                                // alert(_orignalWidth);
                                // alert($('#tab' + tabId).outerHeight());
                                stage.setWidth(($('#tab' + tabId).innerWidth() / 100) * 80);
                                //stage.setHeight(($('#tab' + tabId).outerHeight() / 100) * 80);
                                _resizedWidth = stage.getWidth();
                                _resizedHeight = stage.getHeight();
                                // alert(_resizedWidth);
                                _scaleFactorX = _resizedWidth / _orignalWidth;
                                var _scaleFactorY = _resizedHeight / _orignalHeight;
                                //alert(_scaleFactor);
                                var _images = layer.getChildren();

                                for (var i = 0; i < _images.length; i++) {
                                    if (typeof _images[i].getId() != 'undefined') {
                                        //alert(stage.getScale().x);
                                        _images[i].setX(_images[i].getX() * _scaleFactorX);
                                        //_images[i].setY(_images[i].getY() * _scaleFactorY);
                                        layer.draw();
                                    }
                                }
                            }
