Using URL parameters with Select2

Currently, I am in the process of setting up tagging and utilizing ajax to display the most commonly used tags. To accomplish this, I decided to employ the Select2 plugin. However, I encountered a roadblock when attempting to retrieve my JSON Data in my javascript code. Here is where I stand thus far:

$("#tags").select2({
    ajax: {
        url: "api/v1/tags/",
        dataType: "json",
        cache: true,
        quietMillis: 150,
        allowClear: true,
        data: function(params) {
            return {
               tags: params.term
            }
        },
        processResults: function (data) {
            return {
                results: $.map(data, function(obj) {
                    return { 
                        id: obj.id, 
                        text: obj.slug 
                    };
                })
            };
        }
    },
    tags: true,
    placeholder: "Search or insert tags",
    tokenSeparators: [',', ' '],
});

Unfortunately, I am encountering the following error message:

GET 404 (Not Found)

The JSON Data I have saved is located in these directories: /api/v1/tags/a ... /api/v1/tags/z

I am curious about how to modify the url parameters ?tags=keyword in the Select2 Parameters to /keyword. I have searched through the vendor documentation, but have not found a solution. Can someone provide guidance on this matter? Your assistance would be greatly appreciated.

Answer №1

The issue does not lie within your code, but with the API you are attempting to access. It is returning a 404 error, indicating that you may have either entered an incorrect URL or the resource does not exist.

Instead of utilizing the data parameter, try directly concatenating the Keyword value to the URL string in the following manner:

$("#tags").select2({
  ajax: {
    url: "api/v1/tags/" + keywordValue,
    dataType: "json",
    cache: true,
    quietMillis: 150,
    allowClear: true,
    processResults: function (data) {
      return {
        results: $.map(data, function(obj) {
          return { 
            id: obj.id, 
            text: obj.slug 
          };
        })
      };
    }
  },
    tags: true,
    placeholder: "Search or insert tags",
    tokenSeparators: [',', ' '],
  });
