此结果格式用于将查询结果显示为可切换型视图（switchable views），并提供客户端筛选功能（基于JavaScript）。
此结果格式计划最终取代exhibit格式。当前，仅提供有列表视图list。目前，还不能在不同的视图之间切换。 另外，当前只有取值筛选器value可用。
解析器函数#ask调用的语法如下（这只是一个语法示例。对于当前可用的功能特性，请参见各个类的文档）：
{{#ask:[[SomeCondition]]
|? SomePrintout |+filter=value, someFutureFilter |+value filter switches=and or, disable, select all, select none |+someFutureFilter filter option=someOptionValue
|? SomeOtherPrintout |+filter=value, someOtherFutureFilter |+someOtherFutureFilter filter option=someOptionValue
|format=filtered
|views=list, someFutureView, someOtherFutureView
|list view type=list
|list view template=ListItem
|someFutureView view option=someOptionValue
|someOtherFutureView view option=someOptionValue
}}
筛选器[edit]
取值[edit]
- +value filter switches=and or
Display and AND/OR switch. When OR is checked, clicking >1 filter value will show results containing value1 OR value2 etc. If AND is selected clicking >1 filter value will show results containing value1 AND value2 etc.
- +value filter collapsible=collapsed,uncollapsed
Allows the filter to be collapsed. You can specify whether to default to collapsed or uncollapsed
- +value filter height=xxxpx
Allows you to specify the height of each filter. If the number of values exceeds the specified height, you then get a scrollbar. This is especially useful for filters with large sets of values.
- +filter=distance
Provides a distance slider for the result set based upon a geographic coordinate type property. Additional parameters: |+distance filter origin= e.g. start point or lat/long geographic coordinate |+distance filter unit= e.g. km |+distance filter initial value=x (does not need unit) e.g 100
It should be noted that if Google geocoding is used, this funtionality will result in a lot of API calls. Google has set a limit for the number of free geocodes per day of 2500. It is best to work using lat/long as this currently has no limit.
视图[edit]
列表[edit]
- list view template=<template>
Allows you to specify a template to format the results. This is the same as format=template in standard SMW queries See here for details.
示例查询[edit]
{{#ask:
[[Category:People]]
[[Name::+]]
|?Job Title|+filter=value|+value filter height=150px|+value filter collapsible=collapsed
|?Biog
|?City|+filter=value|+value filter height=200px|+value filter collapsible=uncollapsed
|?Country|+filter=value |+value filter switches=and or|+value filter collapsible=uncollapsed
|format=filtered
|views=list
|list view type=list
}}
This will show a result set with Job Title, City and Country properties set as filters. Job Title filter will start collapsed and will have a scrollbar. City will start uncollapsed and will have a scrollbar. Country will have the AND/OR selector switched on and no scrollbar.
示例距离查询[edit]
{{#ask:
[[Category:People]]
[[Name::+]]
|?Job Title|+filter=value|+value filter height=150px|+value filter collapsible=collapsed
|?Biog
|?City|+filter=value|+value filter height=200px|+value filter collapsible=uncollapsed
|?Coordinates=Distance|+filter=distance|+distance filter origin=London, UK
|+distance filter unit=miles
|+distance filter initial value=5
|format=filtered
|views=list
|list view type=list
}}
This will show a result set with Job Title, City and Country properties set as filters. There will be a distance slider visible that allows you to filter the results based on the distance from London, UK. This assumes each page has a geographic coordinate property set for each person.
示例CSS[edit]
可为筛选器设定皮肤。 默认CSS包含在此扩展的皮肤文件夹当中。 默认CSS将在下方带有结果集的页面之中，采取水平横跨的方式呈现筛选器。
如下CSS示例在呈现时将把筛选器堆放在左侧，而将结果集放在右侧：
.filtered-filters .filtered-value {
overflow: visible;
border: 1px solid #aaa;
padding: 2px;
margin: 0.5em;
margin-bottom:1em;
width:200px;
}
如下是关于折叠控件的CSS示例：
.filtered-filters .filtered-value
.filtered-value-show
{
position: relative;
top: -1em;
right: 0;
float: left;
width: 1.5em;
padding: 0 0.1em;
margin: 0;
cursor: pointer;
text-align: center;
font-size: 90%;
}
.filtered-filters .filtered-value
.filtered-value-hide
{
position: relative;
top: -1em;
right: 0;
float: left;
width: 1.5em;
padding: 0 0.1em;
margin: 0;
background-color: #EAF5E9;
cursor: pointer;
text-align: center;
font-size: 90%;
}
滚动条所需的CSS示例：
.filtered-filters .filtered-value .filtered-value-scrollable {
overflow: auto;
}
启用[edit]
默认情况下，维基站点上并不启用此结果格式。 要启用此格式，必须在文件当中，在包含Semantic Result Formats（语义结果格式） 扩展的下方添加如下一行：
$srfgFormats[] = 'filtered';
