我是 Draw2D.js 的新手,我创建了带有三个子标签的“HorizontalLayout”。并尝试使用三个子标签获取“HorizontalLayout”的 JSON。
我的代码如下:
HTML:
<div id="gfx_holder" style="width: 3000px; height: 3000px; cursor: default"></div>
<pre id="json"
style="overflow:auto; position:absolute; top:10px; right:10px; width:350; height:500; background:white; border:1px solid gray">
</pre>
JS:
var canvas = new draw2d.Canvas("gfx_holder");
var label1 = new draw2d.shape.basic.Label({text: "TEST123"});
var label2 = new draw2d.shape.basic.Label({text: "Label 2"});
var label3 = new draw2d.shape.basic.Label({text: "Label 3"});
var container1 = new draw2d.shape.layout.HorizontalLayout();
container1.add(label1);
container1.add(label2);
container1.add(label3);
container1.setGap(10);
container1.setStroke(2);
canvas.add(container1, 50, 10);
canvas.getCommandStack().addEventListener(function (e) {
if (e.isPostChangeEvent()) {
displayJSON(canvas);
}
});
function displayJSON(canvas) {
var writer = new draw2d.io.json.Writer();
writer.marshal(canvas, function (json) {
$("#json").text(JSON.stringify(json, null, 2));
});
}
上面的代码生成以下输出:
我通过调用displayJSON(canvas)
方法获取 JSON。但我只是得到父(HorizontalLayout
)形状没有得到子标签。
我通过调用displayJSON(canvas)
方法得到以下 JSON:
[
{
"type": "draw2d.shape.layout.HorizontalLayout",
"id": "9c009d71-a2af-6c86-51c4-e9011c9a446d",
"x": 198,
"y": 122,
"width": 184.390625,
"height": 28,
"alpha": 1,
"angle": 0,
"userData": {},
"cssClass": "draw2d_shape_layout_HorizontalLayout",
"ports": [],
"bgColor": "none",
"color": "#1B1B1B",
"stroke": 2,
"radius": 0,
"dasharray": null,
"gap": 10
}
]
我想获得JSON
带有HorizontalLayout
子标签的整个数字。那么,我怎样才能得到它?之后如何显示 Draw2d 图形JSON
?
