使用sap.m.Select
,我的代码如下:
<m:Select
selectedKey='{state}'
items="{
path: 'states>/content',
sorter: {
path: 'name'
}
}">
<core:Item key="{states>id}" text="{states>name}" />
</m:Select>
由于希望能够在其他输入中选择状态时按国家/地区过滤状态,因此,我尝试使用filters
,该文档在以下文档中定义:
问题在于我无法找到如何正确使用它的任何地方(文档,谷歌,SO,源代码,示例,测试)。我尝试了这两种方法但没有成功:
<m:Select
selectedKey='{state}'
items="{
path: 'states>/content',
sorter: {
path: 'name'
},
filters: [{
path: 'countryId',
operator: 'EQ',
value1: '10' // just example
]}
}">
<core:Item key="{states>id}" text="{states>name}" />
</m:Select>
和
# View
<m:Select
selectedKey='{state}'
items="{
path: 'states>/content',
sorter: {
path: 'name'
},
filters: ['.filterByCountry'}
}">
<core:Item key="{states>id}" text="{states>name}" />
</m:Select>
# Controller
...
filterByCountry: new sap.ui.model.Filter({
path: 'countryId',
operator: 'EQ',
value1: '10'
}),
...
有人知道使用它的正确方法吗?
答案 0 :(得分:21)
以下是过滤器在XML视图中的工作原理 - 请参阅下面我为您编写的2个示例(如果他们不在stackoverflow上运行,请使用jsbin链接)。他们都使用Northwind OData服务。你会发现它非常直接:
<Select
items="{
path : '/Orders',
sorter: {
path: 'OrderDate',
descending: true
},
filters : [
{ path : 'ShipCountry', operator : 'EQ', value1 : 'Brazil'}
]
}">
当然,您也可以添加多个过滤器(请参阅下面的第二个示例)。
但是,请记住,过滤器是在XMLView中声明的。不幸的是,UI5当前不是那么动态,只允许使用XMLView中的绑定语法动态更改XMLView中定义的此类过滤器。相反,你需要一些JavaScript代码。在您的情况下,您可以侦听其他字段的更改事件。在事件处理程序中,您只需创建一个新的Filter并应用它:
var oSelect, oBinding, aFilters, sShipCountry;
sFilterValue = ...; // I assume you can get the filter value from somewhere...
oSelect = this.getView().byId(...); //get the reference to your Select control
oBinding = oSelect.getBinding("items");
aFilters = [];
if (sFilterValue){
aFilters.push( new Filter("ShipCountry", FilterOperator.Contains, sFilterValue) );
}
oBinding.filter(aFilters, FilterType.Application); //apply the filter
这应该就是你需要做的一切。下面的示例不使用任何JavaScript代码进行过滤,但我想你明白了。
