我有一个包含ObjectListItems的List,其内容由OData服务提供。其中一个内容是标题,属性的值如下:
title="{ path: 'title', formatter: 'app.schedule.util.Formatter.titleText'}"
正如您所看到的,此标题中有一个格式化程序。 OData将带来像"可用的值#34;或者"禁用"格式化程序会将其转换为用户特定语言的文本。
我在此列表上实现搜索功能并且工作正常,问题是它只搜索"可用"并且"禁用"值,而不是格式化的文本,因为它不是用户识别的值。
过滤器代码为:
handleSearch : function (evt) {
// create model filter
var filters = [];
var query = evt.getParameter("query");
if (query && query.length > 0) {
filters.push(new sap.ui.model.Filter("booked", sap.ui.model.FilterOperator.Contains, query));
filters.push(new sap.ui.model.Filter("weekday", sap.ui.model.FilterOperator.Contains, query));
filters.push(new sap.ui.model.Filter("title", sap.ui.model.FilterOperator.Contains, query));
filters = new sap.ui.model.Filter(filters, false);
}
// update list binding
var list = this.getView().byId("list");
var binding = list.getBinding("items");
binding.filter(filters);
},
如何考虑过滤器上的格式化程序,而不仅仅是原始数据?
答案 0 :(得分:0)
解决方案考虑到您只进行客户端搜索: 假设:如果您在列表中进行分组..
handleSearch : function (evt) {
sFilterPattern = evt.getParameter("query");
sFilterPattern = sFilterPattern.toLowerCase();
var aListItems = this.getView().byId("list").getItems();
var bVisibility;
var oGroupItem = null;
var iCountInGroup = 0;
for (var i = 0; i < aListItems.length; i++) {
if (aListItems[i] instanceof sap.m.GroupHeaderListItem) {
if (oGroupItem) {
if (iCountInGroup == 0) {
oGroupItem.setVisible(false);
} else {
oGroupItem.setVisible(true);
oGroupItem.setCount(iCountInGroup);
}
}
oGroupItem = aListItems[i];
iCountInGroup = 0;
} else {
bVisibility = this.applySearchPatternToListItem(aListItems[i], sFilterPattern);
aListItems[i].setVisible(bVisibility);
if (bVisibility) {
iCountInGroup++;
}
}
}
if (oGroupItem) {
if (iCountInGroup == 0) {
oGroupItem.setVisible(false);
} else {
oGroupItem.setVisible(true);
oGroupItem.setCount(iCountInGroup);
}
}
}
applySearchPatternToListItem:function(oItem, sFilterPattern) {
if (sFilterPattern == "") {
return true;
}
//uncomment to search in oModel data
/*var oIteshellata = oItem.getBindingContext(this.sModelName).getProperty();
for (var sKey in oIteshellata) {
var sValue = oIteshellata[sKey];
// if (sValue instanceof Date) {
// //just for the filter take each number as string
// sValue = sValue.getDate() + "." +
// sValue.getMonth() + "." + sValue.getFullYear();
// }
if (typeof sValue == "string") {
if (sValue.toLowerCase().indexOf(sFilterPattern) != -1) {
return true;
}
}
}*/
// if nothing found in unformatted data, check UI elements
if ((oItem.getIntro() && oItem.getIntro().toLowerCase().indexOf(sFilterPattern) != -1)
|| (oItem.getTitle() && oItem.getTitle().toLowerCase().indexOf(sFilterPattern) != -1)
|| (oItem.getNumber() && oItem.getNumber().toLowerCase().indexOf(sFilterPattern) != -1)

}
// last source is attribute array
var aAttributes = oItem.getAttributes();
for (var j = 0; j < aAttributes.length; j++) {

return true;
