描述问题:

如题,filter过滤器未支持字符串数组

如何复现(请务必完整填写下面内容):
  1. 你是如何使用 amis 的?
    sdk
  2. amis 版本是什么?请先在最新 beta 版本测试问题是否存在
    2.9.0
  3. 粘贴有问题的完整 amis schema 代码:
{
  "type": "page",
  "body": [
    {
      "type": "tpl",
      "tpl": "${xxx|filter:a,b:match:keywords|json}",
      "id": "u:d8233c2649f7"
    }
  ],
  "data": {
    "xxx": [
      {
        "a": "a",
        "b": "m"
      }
    ],
    "keywords": "m"
  },
  "id": "u:4202701508da",
  "regions": [
    "body"
  ]
}

以上schema能在tpl中按预期正常输出结果,如图:

但是data.xxx改为字符串数组时,就未能生效。

{
  "type": "page",
  "body": [
    {
      "type": "tpl",
      "tpl": "${xxx|filter:match:keywords|json}",
      "id": "u:d8233c2649f7",
      "wrapperComponent": ""
    }
  ],
  "data": {
    "xxx": ["a", "m"],
    "keywords": "m"
  },
  "id": "u:4202701508da",
  "regions": [
    "body"
  ]
}

如图,其运行结果为表达式本身了:

按官网filter过滤器的文档说明,见:https://aisuda.bce.baidu.com/amis/zh-CN/docs/concepts/data-mapping#filter 使用方法为 ${xxx | filter[:keys][:directive][:arg1]} ,上面的测试结果表明 [:keys] 是必填项,只能用于对象数组?

filter 确实没考虑字符数组的情况,不过新版公式应该可以使用

${ARRAYFILTER(xxx, item => CONTAINS(item, keywords))}
