使用jquery ajax中的动态数据实现自动完成

Question

I'm using materialize ui in an ASP.Net MVC application and I'm using an autocomplete control with dynamic data.

Here is my code,

<div class="row">
    <div class="col s12">
        <div class="row">
            <div class="input-field col s12">
                <i class="material-icons prefix">textsms</i>
                <input type="text" id="autocomplete-input" class="autocomplete">
                <label for="autocomplete-input">Autocomplete</label>
            </div>
        </div>
    </div>
</div>

This is the jquery ajax call,

$(function () {
    $.ajax({
        type: 'GET', // your request type
        url: "/Home/GetData/",
        success: function (response) {
            var myArray = $.parseJSON(response);

            debugger;
            $('input.autocomplete').autocomplete({
                data: {
                    "Arizona (1)": null,
                    "Florida (2)": null,
                    "Georgia (3)": null,
                    "Hawaii(4)": null, 
                    "Idaho (5)": null,
                    "Illinois (6)": null
                }
            });
        }
    });
});

It can accept data only in this format and this is my response,

"[["Arizona (1)"],["Florida (2)"],["Georgia (3)"],["Hawaii (4)"],["Idaho (5)"],["Illinois (6)"]]"

How do I convert my response into the format that autocomplete understands?

Answer 1

Using ajax API call for materializecss input autocomplete
I have modified as below to obtain autocomplete input for Countries.

You can get the list of country names from API https://restcountries.eu/rest/v2/all?fields=name

 $(document).ready(function() { //Autocomplete $(function() { $.ajax({ type: 'GET', url: 'https://restcountries.eu/rest/v2/all?fields=name', success: function(response) { var countryArray = response; var dataCountry = {}; for (var i = 0; i < countryArray.length; i++) { //console.log(countryArray[i].name); dataCountry[countryArray[i].name] = countryArray[i].flag; //countryArray[i].flag or null } $('input.autocomplete').autocomplete({ data: dataCountry, limit: 5, // The max amount of results that can be shown at once. Default: Infinity. }); } }); }); });

Good day. I can suggest a little different approach. Materialize autocomplete has method

updateData

So if we want to get ajax to load data, we may add event listener to input field

   $(".autocomplete").each(function () {
    let self = this;
    $(this).autocomplete();
    $(this).on("input change", function () {
        $.ajax({
            url: '/source/to/server/data',
            type: 'post',
            cache: false,
            data: {"some": "data"},
            success: function (data) {
                data = JSON.parse(data);
                $(self).autocomplete("updateData", data/*should be object*/);
            },
            error: function (err) {
                console.log(err);
            }
        });
    });
});

Not ideal for different data sources, but may be a starting point.

Not very fancy, but give it a try:

$(function () {
    $.ajax({
        type: 'GET', // your request type
        url: "/Home/GetData/",
        success: function (response) {
            var myArray = $.parseJSON(response);
            var dataAC = {};
            for(var i=0;i<myArray[0].length;i++){
                eval("dataAC." + myArray[0][i] + " = null;");
            }
            debugger;
            $('input.autocomplete').autocomplete({
                data: dataAC
            });
        }
    });
});

Try to convert your response through this way, in your case you don't need the first line of code.

 var responseData = JSON.parse(`[["Arizona (1)"],["Florida (2)"],["Georgia (3)"],["Hawaii (4)"],["Idaho (5)"],["Illinois (6)"]]`); var acArray = []; var acData = {}; responseData.forEach(res => { acArray.push(res.join()) }) acArray.forEach(acObj => { acData[acObj] = null; }) console.log(acData)

Answer 5

you can easily achieve the autocomplete functionality using the Devberidge plugin.

Get Devbridge plugin using https://github.com/devbridge/jQuery-Autocomplete

     <script type="text/javascript">

    $(document).ready(function() {


              $("#country").devbridgeAutocomplete({
                //lookup: countries,
                serviceUrl:"getCountry.php", //tell the script where to send requests
                  type:'POST',


                  //callback just to show it's working
                  onSelect: function (suggestion) {
                     // $('#selection').html('You selected: ' + suggestion.value + ', ' + suggestion.data);
                    },
                showNoSuggestionNotice: true,
                noSuggestionNotice: 'Sorry, no matching results',


              });

    });

  </script>

Here the getCountry.php file returns the JSON data. For more info visit https://ampersandacademy.com/tutorials/materialize-css/materialize-css-framework-ajax-autocomplete-example-using-php
