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。beforeresize和afterResize。
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",
dataType: 'json',
type: 'GET',
data: { tabId: tabId },
cache: false,
success: function (data) {
var bayStatus = [];
var i = 0;
var image_array = [];
var BayExist = false;
var BayCondition;
var imgSrc;
var CanvasBacgroundImage;
var _X;
var _bayNumber;
var _Y;
var _ZoneName;
$(data).each(function (i, val) {
i = i + 1;
if (!BayExist) {
bayStatus = val.BayStatus;
CanvasBacgroundImage = val.TabImageLocation;
BayExist = true;
}
$.each(val, function (k, v) {
if (k == "BayNumber") {
BayCondition = bayStatus[v];
_bayNumber = v;
if (BayCondition == "O")
imgSrc = "../../images/Parking/OccupiedCar.gif"
else if (BayCondition == "N")
imgSrc = "../../images/Parking/OpenCar.gif";
}
if (k == "BayX")
_X = v;
if (k == "BayY")
_Y = v;
if (k == "ZoneName")
_ZoneName = v;
});
image_array.push({ img: imgSrc, xAxis: _X, yAxis: _Y, toolTip: _bayNumber, ZoneName: _ZoneName });
});
var imageUrl = CanvasBacgroundImage;
if ($('#tab' + tabId).length) {
// $('#tab' + tabId).css('background-image', 'url("../../images/Parking/' + imageUrl + '")');
var stage = new Kinetic.Stage({
container: 'tab' + tabId,
width: ($('#tab' + tabId).innerWidth() / 100) * 80, // 80% width of the window.
height: 308
});
window.onresize = function (event) {
stage.setWidth(($('#tab' + tabId).innerWidth() / 100) * 80);
}
$('#tab' + tabId).find('.kineticjs-content').css({ 'background-image': 'url("../../images/Parking/' + imageUrl + '")', 'background-repeat': ' no-repeat', 'background-size': '100% 100%' });
var layer = new Kinetic.Layer();
var planetOverlay;
function writeMessage(message, _x, _y) {
text.setX(_x + 20);
text.setY(_y + 1);
text.setText(message);
layer.draw();
}
var text = new Kinetic.Text({
fontFamily: 'Arial',
fontSize: 14,
text: '',
fill: '#000',
width: 200,
height: 60,
align: 'center'
});
var opentooltip = new Opentip(
"div#tab" + tabId, //target element
"dummy", // will be replaced
"", // title
{
showOn: null // I'll manually manage the showOn effect
});
Opentip.styles.win = {
borderColor: "black",
shadow: false,
background: "#EAEAEA"
};
Opentip.defaultStyle = "win";
// _timer = setInterval(function () {
for (i = 0; i < image_array.length; i++) {
img = new Image();
img.src = image_array[i].img;
planetOverlay = new Kinetic.Image({
x: image_array[i].xAxis,
y: image_array[i].yAxis,
image: img,
height: 18,
width: 18,
id: image_array[i].toolTip,

});
planetOverlay.on('mouseover', function () {
opentooltip.setContent("<span style='color:#87898C;'><b>Bay:</b></span> <span style='color:#25A0D3;'>" + this.getId() + "</span><br> <span style='color:#87898C;'><b>Zone:</b></span><span style='color:#25A0D3;'>" + this.getName() + "</span>");
//writeMessage("Bay: " + this.getId() + " , Zone: " + this.getName(), this.getX(), this.getY());//other way of showing tooltip
opentooltip.show();
$("#opentip-1").offset({ left: this.getX(), top: this.getY() });
});
planetOverlay.on('mouseout', function () {
opentooltip.hide();
// writeMessage('');
});
planetOverlay.createImageHitRegion(function () {
layer.draw();
});
layer.add(planetOverlay);
layer.add(text);
stage.add(layer);
}
// clearInterval(_timer);
//$("#tab3 .kineticjs-content").find("canvas").css('background-image', 'url("' + imageUrl + '")');
// },
// 500)
}
}
,
error: function (result) {
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();
}
}
}
