更新要素属性

此示例演示如何使用 FeatureLayer.applyEdits() 更新现有要素的属性。此示例使用 FeatureForm 微件通过在用户选择视图上的要素时调用 applyEdits 函数来更新现有功能的属性。

表单的字段通过表单模板进行配置。此模板接受组合成组的字段元素数组具有分组字段配置提供了更易于管理的编辑工作流程。此示例使用自动转换为组元素的嵌套元素。

formTemplate: { // Autocasts to new FormTemplate
  title: "Damage assessments",
  description: "Provide information for insurance",
  elements: [
    { // Autocasts to new GroupElement
      type: "group",
      label: "Inspector Information",
      description: "Field inspector information",
      elements: [
        { // Autocasts to new FieldElement
          type: "field",
          fieldName: "inspector",
          label: "name"
        },
        {
          type: "field",
          fieldName: "inspemail",
          label: "Email address",
          visibilityExpression: "alwaysHidden" // reference to an expression defined under "expressionInfos"
        },
        {
          type: "field",
          fieldName: "insp_date",
          label: "Date of inspection"
        }
      ]
