 2、绘图引擎 zrender 地址  ZRender 文档 (ecomfe.github.io)

 3、 文件保存格式json 

 

 

4、创建并初始化

        <div id="maingrid" style="position: static; width: 100%; height: 100%;  box-sizing: border-box ">
            <div id="grid" style="position: relative; width: 1200px; height: 600px;  "> </div>
        </div>

    <script type="text/javascript">
        var domgrid = document.getElementById("grid");
        var input = document.getElementById("maininput");
        var grid = new DataExcel();
        grid.Width = domgrid.Width;
        grid.Height = domgrid.Height;
        grid.InitDom(domgrid);
        grid.InitEdit(input);
        grid.Refresh();
        grid.Paint();
        grid.On(Events.FocusedCellChanged, FocusedCellChanged);
        function FocusedCellChanged(args)
        
            console.log("事件触发测试:" + args);
        
    </script>

 5、文件 新建保存

    <!--File-->
    <script type="text/javascript">
        function New()
        
            grid.Clear();
            grid.VScroll.Visible = true;
            grid.HScroll.Visible = true;
            grid.Refresh();
            grid.RePaint();
        
        function Open()
        
            let inputObj = document.createElement('input')
            inputObj.setAttribute('id', '_ef');
            inputObj.setAttribute('type', 'file');
            inputObj.setAttribute("style", 'visibility:hidden');
            document.body.appendChild(inputObj);
            inputObj.addEventListener("change", fileopen)
            //inputObj. = fileopen()
            inputObj.click();
        
        function fileopen(e)
        
            let inputObj = e.target;
            let file = inputObj.files[0];
            console.log(file);
            grid.OpenFile(file);

            document.body.removeChild(inputObj);
            grid.Refresh();
            grid.RePaint();
        
        function Save()
        
            //let domfile = document.getElementById("file");
