Search Box 搜索框 0 ⚙ 组件 Search Box

基本用法

用于展示一个简单搜索框,通常需要搭配其他组件使用。比如 page 配置 initApi 后,可以用来实现简单数据过滤查找,name keywords 会作为参数传递给 page 的 initApi

{
    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "search-box",
        "name": "keywords"
      },

      {
        "type": "tpl",
        "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
      }
    ]
}

禁用样式

6.0.0及以上版本

{
    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "flex",
        "direction": "column",
        "justify": "flex-start",
        "alignItems": "flex-start",
        "items": [
          {
            "type": "search-box",
            "name": "keywords",
            "disabled": true,
            "style": {
              "marginBottom": "10px"
            }
          },
          {
            "type": "search-box",
            "name": "keywords",
            "mini": true,
            "disabled": true
          }
        ]
      }
    ]
}

加载状态

6.0.0 及以上版本

设置"loading": true, 标识开关操作的异步任务仍在执行中。另外loadingOn支持表达式,配合ajax动作实现搜索操作时的loading状态。

{
  "type": "page",
  "id": "demo-page",
  "data": {
    "isFetching": false,
    "fetched": false
  },
  "body": [
    {
      "type": "search-box",
      "name": "keywords",
      "clearable": true,
      "loadingOn": "${isFetching}",
      "className": "mb-2",
      "onEvent": {
        "search": {
          "actions": [
            {
              "actionType": "setValue",
              "componentId": "demo-page",
              "args": {
                "value": {
                  "isFetching": true
                }
              }
            },
            {
              "actionType": "toast",
              "args": {
                "msgType": "warning",
                "msg": "开始检索..."
              }
            },
            {
              "actionType": "ajax",
              "api": {
                "url": "/api/mock2/sample?perPage=5&waitSeconds=2&keywords=${keywords}",

                "messages": {
                  "success": "检索完成",
                  "failed": "检索失败"
                }
              }
            },
            {
              "actionType": "setValue",
              "componentId": "demo-page",
              "args": {
                "value": {
                  "isFetching": false,
                  "fetched": true,
                  "total": "${event.data.responseResult.count}",
                  "datasource": "${event.data.responseResult.rows}"
                }
              }
            }
          ]
        }
      }
    },

              "labelMap": {
                "success": "检索成功:"
              }
            },
            {
              "type": "tpl",
              "tpl": "总计${total}条当前仅展示5条"
            },
          ]
        },
        {
          "type": "list",
          "source": "${datasource}",
          "listItem": {

                    "label": "Version"
                  }
                ]
              }
            ]
          }
        }
      ]
    }
  ]
}

加强样式

{
    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "search-box",
        "name": "keywords",
        "enhance": true
      },

      {
        "type": "tpl",
        "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
      }
    ]
}

可清除

{
    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "search-box",
        "name": "keywords",
        "clearable": true
      },

      {
        "type": "tpl",
        "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
      }
    ]
}

清除后立即搜索

    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "search-box",
        "name": "keywords",
        "clearable": true,
        "clearAndSubmit": true
      },

      {
        "type": "tpl",
        "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
      }
    ]
}

{
    "type": "page",
    "initApi": "/api/mock2/page/initData?keywords=${keywords}",
    "body": [
      {
        "type": "search-box",
        "name": "keywords",
        "mini": true
      },

      {
        "type": "tpl",

        {
            "name": "grade",
            "label": "CSS grade"
        }
    ]
}

          {
            "type": "search-box",
            "name": "keywords"
          },

          {

            "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
          }
        ]
      }

    ]
}

立刻搜索模式

设置 "searchImediately": true 实现输入时即搜索

{
    "type": "page",
    "body": [
      {
        "type": "service",
        "api": "/api/mock2/page/initData?keywords=${keywords}",
        "body": [
          {
            "type": "search-box",
            "name": "keywords",
            "searchImediately": true
          },
          {
            "type": "tpl",
            "tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
          }
        ]
      }
    ]

事件表

2.4.1 及以上版本

当前组件会对外派发以下事件,可以通过onEvent来监听这些事件,并通过actions来配置执行的动作,在actions中可以通过${事件参数名}${event.data.[事件参数名]}来获取事件产生的数据,详细请查看事件动作

[name]表示当前组件绑定的名称,即name属性,如果没有配置name属性,则通过value取值。

事件名称 事件参数 说明
search [name]: string 组件的值 点击搜索图标时触发
change [name]: string 组件的值 输入框值变化时触发
