MaterializeCssでオートコンプリートフォームを作成する方法

Question

MaterializeCssのオートコンプリートフォーム、このためのプラグインを探していますか？私はselect2を使用しようとしましたが、それはCSSが良く見えません

Answer 1

マテリアライズは素晴らしいライブラリです。私はそれを動作させることができました。

$('document').ready(function() {

  var input_selector = 'input[type=text], input[type=password], input[type=email], input[type=url], input[type=tel], input[type=number], input[type=search], textarea';
  
  
/**************************
* Auto complete plugin  *
*************************/
  
  
  $(input_selector).each(function() {
    var $input = $(this);

    if ($input.hasClass('autocomplete')) {
      var $array = $input.data('array'),
        $inputDiv = $input.closest('.input-field'); // Div to append on
      // Check if "data-array" isn't empty
      if ($array !== '') {
        // Create html element
        var $html = '<ul class="autocomplete-content hide">';

        for (var i = 0; i < $array.length; i++) {
          // If path and class aren't empty add image to auto complete else create normal element
          if ($array[i]['path'] !== '' && $array[i]['path'] !== undefined && $array[i]['path'] !== null && $array[i]['class'] !== undefined && $array[i]['class'] !== '') {
            $html += '<li class="autocomplete-option"><img src="' + $array[i]['path'] + '" class="' + $array[i]['class'] + '"><span>' + $array[i]['value'] + '</span></li>';
          } else {
            $html += '<li class="autocomplete-option"><span>' + $array[i]['value'] + '</span></li>';
          }
        }

        $html += '</ul>';
        $inputDiv.append($html); // Set ul in body
        // End create html element

        function highlight(string) {
          $('.autocomplete-content li').each(function() {
            var matchStart = $(this).text().toLowerCase().indexOf("" + string.toLowerCase() + ""),
              matchEnd = matchStart + string.length - 1,
              beforeMatch = $(this).text().slice(0, matchStart),
              matchText = $(this).text().slice(matchStart, matchEnd + 1),
              afterMatch = $(this).text().slice(matchEnd + 1);
            $(this).html("<span>" + beforeMatch + "<span class='highlight'>" + matchText + "</span>" + afterMatch + "</span>");
          });
        }

        // Perform search
        $(document).on('keyup', $input, function() {
          var $val = $input.val().trim(),
            $select = $('.autocomplete-content');
          // Check if the input isn't empty
          $select.css('width',$input.width());

          if ($val != '') {
            $select.children('li').addClass('hide');
            $select.children('li').filter(function() {
              $select.removeClass('hide'); // Show results

              // If text needs to highlighted
              if ($input.hasClass('highlight-matching')) {
                highlight($val);
              }
              var check = true;
              for (var i in $val) {
                if ($val[i].toLowerCase() !== $(this).text().toLowerCase()[i])
                  check = false;
              };
              return check ? $(this).text().toLowerCase().indexOf($val.toLowerCase()) !== -1 : false;
            }).removeClass('hide');
          } else {
            $select.children('li').addClass('hide');
          }
        });

        // Set input value
        $('.autocomplete-option').click(function() {
          $input.val($(this).text().trim());
          $('.autocomplete-option').addClass('hide');
        });
      } else {
        return false;
      }
    }
  });

更新1/09/2016：オートコンプリートはすでに公式に利用可能です： http://materializecss.com/forms.html#autocomplete =

全く同じものを探していたのでラッキーだったと思います。彼らは最近オートコンプリートを追加しました（まだドキュメントにはありません）。しかし、あなたはここで情報を見ることができます https://github.com/SuperDJ/materialize/commit/3648f74542e41c3b3be4596870b7485f6ebdf176#diff-e4535828acef79852aa104417c16fe3dR157

デモのリンクにアクセス https://ampersandacademy.com/demo/autocomplete/

devberidgeプラグインを使用して、オートコンプリート機能を簡単に実現できます。

https://github.com/devbridge/jQuery-Autocomplete を使用してDevbridgeプラグインを取得します

 <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',


          });

});

ここで、getCountry.phpファイルはJSONデータを返します。詳細については https://ampersandacademy.com/tutorials/materialize-css/materialize-css-framework-ajax-autocomplete-example-using-php をご覧ください。

SuperDJ（ https://goo.gl/0Mbrtg ）によって行われたコミットによると、私はそれをうまく動作させることができませんでした...

ここにコードがあります：

  <div class="row">
                <div class="col s12">
                    <div class="row">
                        <div class="input-field col s12">
                            <input type="text" id="autocomplete" class="autocomplete highlight-matching" data-array='[{"value": "example","path": "","class": ""},{"value": "example 2","path": "","class": ""},{"value": "test","path": "","class": ""}]'>
                            <label for="autocomplete">Autocomplete</label>
                        </div>
                    </div>
                </div>
            </div>

ここにcodepenテストがあります：

この作業を行うには、助けが必要です。

Answer 6

上記のように、オートコンプリートにはマテリアライズフレームワークが追加されていますが、それでもかなり制限があります。値（IDなど）のアイコンとテキストをサポートするソリューションを待っています。

再： https://github.com/Dogfalo/materialize/issues/4086

Answer 7

ごとに、 ここ です。

あなたはこの単純なことをするだけです（例からそこにのみ）：

HTML:

<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>

JS:

$('input.autocomplete').autocomplete({
    data: {
      "Apple": null,
      "Microsoft": null,
      "Google": null
   }
});

Answer 8

$（document）.ready（function（）{}）;内に初期化スクリプトを書き込むだけです。

つまり.

$(document).ready(function(){
    $('input.autocomplete').autocomplete({
        data: {
            "Apple": null,
            "Microsoft": null,
            "Google": null
        }
     });
});
