您好我有两个剑道ui drodDownList:
kendo-drop-down-list(
ng-model = 'vm.firstList'
k-data-source='vm.filterData'
k-data-text-field='"title"'
k-data-value-field='"name"'
k-value-primitive='true'
k-filter='"contains"'
k-on-change='vm.onChange($event)'
)
和
kendo-drop-down-list(
ng-model = 'vm.secondList'
k-data-source='vm.filterData'
k-data-text-field='"title"'
k-data-value-field='"name"'
k-value-primitive='true'
k-filter='"contains"'
k-on-change='vm.onChange($event)'
)
它是数据源:
this.filterData = [
{ name: 'Brown', title: 'Soier' },
{ name: 'Maks', title: 'Inkl' },
{ name: 'Lint', title: 'Baks' },
{ name: 'Hover', title: 'Niyou' }
]
他们有相同的数据源,我想在第一个dd中选择项目然后从其他dd中删除此项目(同样为第二个dd)。同时,无法选择两个相同的元素。
答案 0 :(得分:0)
我的解决方案:
在第一个dd中添加:
k-on-change='vm.onFirstSelect(kendoEvent)'
k-data-source='vm.firstFilterElements'
第二个dd:
k-on-change='vm.onSecondSelect(kendoEvent)'
k-data-source='vm.secondFilterElements'
控制器中的添加:
this.filterElements = [
{ name: 'Brown', title: 'Soier' },
{ name: 'Maks', title: 'Inkl' },
{ name: 'Lint', title: 'Baks' },
{ name: 'Hover', title: 'Niyou' }
]
this.firstFilterElements = this.filterElements;
this.secondFilterElements = this.filterElements;
onFirstSelect(e) {
this.secondFilterElements = this.filterByItem(e);
}
onSecondSelect(e) {
this.firstFilterElements = this.filterByItem(e);
}
filterByItem (e) {
return this.filterElements.filter(function (el) {
return el.name !== e.sender.dataItem(e.item)
[e.sender.options.dataValueField];
});
}
如果有人可以优化它,我会很高兴)
