Select2不使用我的templateResults或templateSelection选项 [英] Select2 not using my templateResults or templateSelection options

问题描述

我正在尝试将select2 ajax调用与模板一起使用.我可以正常使用ajax，但是它没有使用我的模板功能.

I am trying to use the select2 ajax call with templates. I am getting the ajax in just fine but it is not using my template functions.

ajax数据是:

[
   {"name":"First thing","otherData":"asdfg"},
   {"name":"Second thing","otherData":"qqerr"},
   {"name":"third thing","otherData":"yerty"},
   {"name":"fourth thing","otherData":"hgjfgh"},
   {"name":"fifth thing","otherData":"fhgkk"}
]

select2代码(我从此处花费了很多时间)是:

the select2 code (which i took a lot from here ) is:

FundSearch = {
    create: function (selector, theURL) {
      $(selector).select2({
        ajax: {
          url: theURL,
          dataType: 'json',
          delay: 250,
          data: function (params) {
            console.log(params.term);
            return {
              q: params.term, // search term
              page: params.page
            };
          },
          results: function (data, page) {
            // parse the results into the format expected by Select2.
            // since we are using custom formatting functions we do not need to
            // alter the remote JSON data
            return {
              results: data
            };
          },
          cache: true
        },
        escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
        minimumInputLength: 1,
        templateResult: formatData,
        templateSelection: formatDataSelection
      });

      function formatData (data) {
          if (data.loading) return data.name;

          markup = "<h1>" + data.name + "</h1>" + "<p>" + data.otherData + "</p>";

          return markup;
        }

        function formatDataSelection (data) {
          return data.name;
        }


    }
};

我得到的错误是Uncaught TypeError: Cannot read property 'toUpperCase' of undefined在select2.js的第356行上，版本为:3.5.2.

The error I am getting is Uncaught TypeError: Cannot read property 'toUpperCase' of undefined on line 356 of select2.js for Version: 3.5.2.

在我看来，select2没有使用我的templateSelection和templateResults函数.

It seems to me that select2 is not using my templateSelection and templateResults function.

推荐答案

您正在查看4.0.0文档，但正在使用3.5.2. 您仍然可以访问3.5.2文档.

You are looking at the 4.0.0 documentation but are using 3.5.2. You can still access the 3.5.2 documentation.

具体地说，templateSelection和templateResult选项仅在4.0.0中存在.在3.5.2中将它们分别称为formatSelection和formatResult.

Specifically, the templateSelection and templateResult options only exist in 4.0.0. They were called formatSelection and formatResult in 3.5.2.
