Question

我需要使用 jquery 更新 rappidjs 的单元格属性的值。我们怎么能做到这一点？

Answer 1

某处需要做类似的工作

makeIconInElements(app.graph.toJSON());

function makeIconInElements(json2) {

    if (json2 != undefined) {
       let changedJson = json2;

        changedJson.cells.forEach(function (cell) {
            if (cell.type == ){ }

     

        });
        app.graph.fromJSON(changedJson);
        //resizeCell(app.paper.model);

        //Resizing the cell if icons are outside the box.
        changedJson.cells.forEach(function (cell) {
            let getAllCells = app.graph.getCells();
            if (cell.showIcons) {
                let currentResizingStep = getAllCells.filter(function (el) { return el.attributes.id == cell.id; });
                autoResize(app, currentResizingStep[0]);
            }
        });

        if (lastModifiedStep.attrs.task.status != abs") {
            currentRunningPosition = lastModifiedStep.position;
            app.paperScroller.scroll(currentRunningPosition.x, currentRunningPosition.y);
        }
    }
}
