如何使用 MaterializeCss 创建自动完成表单？

Question

我正在寻找 MaterializeCss 的自动完成表单，有任何插件吗？我曾尝试使用 select2，但 css 看起来不太好

Answer 1

Materialize 是一个很棒的库，我能够让它工作。

$('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;
      }
    }
  });






});

我一直在寻找完全相同的东西，我认为我们很幸运。他们最近添加了自动完成功能（尚未在文档中）。但是你可以在这里看到信息https://github.com/SuperDJ/materialize/commit/3648f74542e41c3b3be4596870b7485f6ebdf176#diff-e4535828acef79852aa104417c16fe3dR157

下载这个 js 并保存在你的 js 文件夹 jquery.materialize-autocomplete.js 中，你可以覆盖 onSelect,minLength,showListOnFocus

访问演示链接https://ampersandacademy.com/demo/autocomplete/

您可以使用 Devberidge 插件轻松实现自动完成功能。

使用https://github.com/devbridge/jQuery-Autocomplete获取 Devbridge 插件

 <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',


          });

});

这里的 getCountry.php 文件返回 JSON 数据。欲了解更多信息，请访问https://ampersandacademy.com/tutorials/materialize-css/materialize-css-framework-ajax-autocomplete-example-using-php

根据 SuperDJ (https://goo.gl/0Mbrtg) 的提交，我没能成功...

代码如下：

  <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>

这是一个代码笔测试：

需要一些帮助才能完成这项工作。

Answer 6

根据here。

你只需要做这个简单的事情（仅从那里的例子）：

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
   }
});

你可以使用上面的.js文件，你可以覆盖

Onselect
 showListOnFocus: false,
            minLength:2

根据您的要求，它将起作用。

Answer 8

只需在 $(document).ready(function(){}); 中编写初始化脚本；

即

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

如上所述，物化框架中添加了自动完成功能，但它仍然非常有限。我正在等待支持值（例如 ID）图标和文本的解决方案。
