Multiselect(多选控件)

该控件提供一组复选框。

multiselect_editor

注释

请确保在 lightbox 中使用该控件前已启用 multiselect 扩展。

scheduler.plugins({
multiselect: true /*!*/
});

scheduler.locale.labels.section_userselect = "Participants";

scheduler.config.lightbox.sections="["
{ name:"description", height:50, map_to:"text", type:"textarea", focus:true },
{ name:"userselect", height:22, map_to:"user_id", type:"multiselect",
options: scheduler.serverList("users"), vertical:"false" },
{ name:"time", height:72, type:"time", map_to:"auto"}
];

初始化

要在 lightbox 中包含 Multiselect 控件,请按照以下步骤操作:

  1. 在页面上启用 'multiselect' 扩展:
scheduler.plugins({
multiselect: true
});
  1. 将 multiselect 区块添加到 lightbox 配置中:
scheduler.config.lightbox.sections = 
{ name:"description", ... },
{ name:"userselect", height:22, map_to:"user_id", type:"multiselect",
options: scheduler.serverList("user_id"), vertical:false },
{ name:"time", ...}
];
  1. 为该区块定义标签:
scheduler.locale.labels.section_userselect = "Participants";

属性

以下是 'multiselect' 控件常用的一些关键属性(完整属性列表请参见 这里):

为控件填充数据

通常,通过 options 参数为 multiselect 按钮设置可选值:

scheduler.config.lightbox.sections = 
{ name:"userselect", type:"multiselect",
...
options:[
{ key: 1, label: 'George' },
{ key: 2, label: 'Nataly' },
{ key: 3, label: 'Diana' },
{ key: 4, label: 'Adam' }
]},
...
];

options 数组中的每个项都必须包含以下两个必需属性:

  • key - 选项的唯一 ID
  • label - 选项显示的文本标签

从服务器填充复选框

要从服务器获取复选框的值,请使用 serverList 方法:

scheduler.config.lightbox.sections = [
{name:"description", ...},
{ name:"userselect", height:22, map_to:"user_id", type:"multiselect",
options: scheduler.serverList("users"), vertical:"false" },
{name:"time", ...}
];

scheduler.load("api/data");

这里,api/data 是一个 服务端脚本,返回事件以及 multiselect 按钮的选项,其格式如 데이터 포맷 예시 所示:

//response
{
"data":[
{
"id":"1",
"start_date":"2019-03-02 00:00:00",
"end_date":"2019-03-04 00:00:00",
"text":"dblclick me!",
"user_id":"1,2"
},
{
"id":"2",
"start_date":"2019-03-09 00:00:00",
"end_date":"2019-03-11 00:00:00",
"text":"and me!",
"user_id":"2,3"
}
],
"collections": {
"users":[
{"value":"1","label":"Lisa"},
{"value":"2","label":"Bob"},
{"value":"3","label":"Mike"}
]
}
}
注释

可以使用 updateCollection 方法动态更新选项列表。

var oldOptions = scheduler.serverList("users").slice();
scheduler.updateCollection("users", [
{"value":"4","label":"John"},
{"value":"5","label":"Paul"},
{"value":"6","label":"Ringo"},
{"value":"7","label":"George"}
]);

动态加载

在静态模式下,所有事件参数选项都作为独立字段存储在数据库中,这样可以实现更灵活的逻辑,但需要额外的查询来加载全部选项。

在动态模式下,只有在需要时才加载选项。这减少了查询次数,但限制了自定义逻辑的实现能力。

在服务端,你应有类似如下的代码。

要启用动态模式,请在 options 属性旁添加 script_url 属性:

scheduler.config.lightbox.sections = [
{name:"userselect", height:22, map_to:"user_id", type:"multiselect",
options: scheduler.serverList("user_id"),
script_url:'api/options'},
...
];

api/options 端点应返回如下 JSON 数据:

[                          
{"value":"1","label":"Lisa"},
{"value":"2","label":"Bob"},
{"value":"3","label":"Mike"}
]
