vue中使用mxgraph的方法实例代码详解

var mxgraph = require("mxgraph")(
{ // 以下地址不需要修改
mxImageBasePath: "./src/images", 
mxBasePath: "./src"
})

var mxEvent = mxgraph.mxEvent;
mxEvent.disableContextMenu(container);

import mx from 'mxgraph';
const mxgraph = mx({
 mxImageBasePath: './src/images',
 mxBasePath: './src'
});
// decode bug https://github./jgraph/mxgraph/issues/49
window.mxGraph = mxgraph.mxGraph;
window.mxGraphModel = mxgraph.mxGraphModel;
window.mxEditor = mxgraph.mxEditor;
window.mxGeometry = mxgraph.mxGeometry;
window.mxDefaultKeyHandler = mxgraph.mxDefaultKeyHandler;
window.mxDefaultPopupMenu = mxgraph.mxDefaultPopupMenu;
window.mxStylesheet = mxgraph.mxStylesheet;
window.mxDefaultToolbar = mxgraph.mxDefaultToolbar;
export default mxgraph;

import mxgraph from 'index.js';
const {mxGraph, mxClient, mxCodec, mxUtils, mxConstants, mxPerimeter} = mxgraph;

mounted () {
      if (!mxClient.isBrowserSupported()) {
        // 判断是否支持mxgraph
        mxUtils.error('Browser is not supported!', 200, false);
      } else {
        // 再容器中创建图表
        let container = document.getElementById('graphContainer');
        let MxGraph = mxGraph;

        var graph = new MxGraph(container);
        // 生成 Hello world!

        this.getXml = mxUtils.getXml(xx);
      }
