选择二：＆QUOT;文字是未定义＆QUOT;获取JSON时用ajax [英] select2: "text is undefined" when getting json using ajax

问题描述

我在收到的JSON结果反馈给选择2时的一个问题。我的JSON不返回的结果，有一个文本字段，以便需要格式化的结果，这样选择二接受名称。

I'm having an issue when getting json results back to select2. My json does not return a result that has a "text" field so need to format the result so that select2 accepts "Name".

这code如果在JSON文本字段设置为文本，但在这种情况下，我不能改变的JSON结果（我的控制范围之内code）格式的作品。

This code works if the text field in the json is set to "text" but in this case, I cannot change the formatting of the json result (code outside my control).

$("#e1").select2({                                
    formatNoMatches: function(term) {return term +" does not match any items." },
    ajax: { // instead of writing the function to execute the request we use Select2's convenient helper
    url: "localhost:1111/Items.json",
    dataType: 'jsonp',
    cache: true,
    quietMillis: 200,
    data: function (term, page) {
            return {
                q: term, // search term
                p: page,
                s: 15               
            };
        },
    results: function (data, page) { // parse the results into the format expected by Select2.          
        var numPages = Math.ceil(data.total / 15);                
        return {results: data.Data, numPages: numPages};
        }
    }      
});

我已经调查的文档，发现了一些语句就可以投入的结果，如

I have looked into the documentation and found some statements you can put into the results such as

text: 'Name',

但我仍然得到文本未定义。

but I am still getting "text is undefined".

感谢您的帮助。

推荐答案

注意，选择2始终处于{ID，文字}对，所以你需要指定

note that select2 is always in {id,text} pair so you need to specify both

results: function (data, page) {
            var newData = [];
            _.each(data, function (item) {
                newData.push({
                    id: item.Id  //id part present in data 
                  , text: item.DisplayString  //string to be displayed
                });
            });
            return { results: newData };
        }
    },
