融合甘特图不会在使用标签的自定义功能时绘制日期

问题描述 投票：0回答：1

嗨，我想将json值显示为我的甘特图标签。所以，我尝试过这样的事情

"processes": {
    "headertext": "Task",
    "align": "left",
    "process": processLabels 
  }

processLabels具有返回一组数组值的函数。简单的功能如下

function genChart() {
    var milestones = ["task1","task2","task3"];
    var processLabels = [] 
    for (var i=0;i<=2;i++) {
        processLabels.push({
            "label":  '"'+milestones[i]+'"'  ,
        "id": '"'+i+'"'
        });

    }
    return processLabels;
}

问题是我只得到标签，日期没有绘制enter image description here

      <body>
      <div id="chart-container"></div>
      </body>
    </head>
    </html>

请让我知道如何解决这个问题。

您没有获得任务栏，因为您生成的processLabels数组正在错误地创建标签和id对象值请从对象中删除空白引号以使其工作，这是更新的实现

function genChart() {
    var milestones = ["task1", "task2", "task3"];
    var processLabels = []
    for (var i = 0; i <= 2; i++) {
      processLabels.push({
        "label": '' + milestones[i] + '',
        "id": '' + i + ''
      });

    }
    return processLabels;
  }
