SAPUI5:如何过滤具有 2 个或更多值的数据 [英] SAPUI5: How to filter data with 2 or more values

问题描述

我目前正在/在 SAPUI5 中尝试一些东西，我已经实现了一个非常简单的搜索，如下所示:

I'm currently trying some stuff with/in SAPUI5 and I've implemented a very simple search like this:

    var filters = [];
    var query = evt.getParameter("query");
    if (query && query.length > 0) {
        var nameFilter = new sap.ui.model.Filter("name", sap.ui.model.FilterOperator.Contains, query);

        filters.push(nameFilter);
    }

    var list = this.getView().byId("list");
    var binding = list.getBinding("items");
    binding.filter(filters);

现在我有以下问题:通过这个逻辑，我可以按人名搜索或过滤.我还有一些额外的字段，如年龄、性别等，我也想搜索年龄或性别.所以我尝试创建第二个过滤器，比如genderFilter"，它使用gender"字段.在此之后，使用 .push() 方法将第二个过滤器添加到过滤器 [].. 但这不起作用.

Now I have following issue: with this logic I can just search, or rather filter, by the name of a person. I've also some additional fields like age, gender, etc and I want to perform a search for the age or gender, too. So I've tried to create a 2nd filter, like "genderFilter", which is using the "gender" field. After this adding this 2nd filter with the .push() method to the filters[]..but this isn't working.

我已经尝试观看文档，观看不同的示例，尝试不同的方法 - 但我很无助.请有人帮我解决这个问题吗?

I've already tried to watch the documentation, watched different examples, tried different ways - but I'm helpless. Can please someone help me with this issue?

推荐答案

对于要求，此代码将起作用.

For the requirement this code will work.

var list = this.getView().byId("list");
var binding = list.getBinding("items");
if( !query ) {
    binding.filter( [] );
} 
else {
   binding.filter( [ new sap.ui.model.Filter([
      new sap.ui.model.Filter("name", sap.ui.model.FilterOperator.Contains, query ),
      new sap.ui.model.Filter("gender", sap.ui.model.FilterOperator.Contains, query )
   ],false)
]
