jquery - Bootstrap 输入字段中的 jQuery 自动完成样式

Question

我已经为 Bootstrap 输入实现了 jQuery 自动完成功能。 jQuery 自动完成工作正常，但我想以组合形式查看结果，我想它现在正在发生，因为我正在使用 BootStrap。

这是我分配自动完成功能的字段:

<div class="form-group">
  <label>Employee</label>
  <input class="form-control" name="txtEmployee" placeholder="Trabajador">
</div>

$(this).autocomplete({

  source: function(request, response) {
    $.ajax({
      url: '@Url.Content("~/Employee/SearchEmployee")/',
      type: 'POST',
      contentType: 'application/json',
      dataType: "json",
      data: JSON.stringify({
          employerId: 1,
          searchStr: me.val()
      }),
      success: function(data) {
        if (data.success) {

          response($.map(data.data, function(item) {

            return {
              label: "(" + item.EmployeeNumber + ") " + 
                           item.FirstName + " " + 
                           item.MothersLast + ", " + 
                           item.FathersLast,
              employeeId: item.EmployeeId
            }
          }));
        } 
      }
    });
  },
  minLength: 3
});

结果显示如下:

如何使用 Bootstrap 设置结果的样式，以便我可以像下拉列表一样查看它们？

Answer 1

如果您使用 jQuery-UI，则必须包含 jQuery UI CSS 包，否则 UI 组件不知道如何设置样式。

如果您不喜欢 jQuery UI 样式，那么您必须重新创建本来会应用的所有样式。

这是一个示例和一些可能的修复方法。

Minimal, Complete, and Verifiable example (即损坏)

这是 Stack Snippets 中的演示没有 jquery-ui.css(不起作用)

$(function() {
  var availableTags = [
    "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++",
    "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran",
    "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl",
    "PHP", "Python", "Ruby", "Scala", "Scheme"
  ];
  
  $(".autocomplete").autocomplete({
    source: availableTags
  });
});

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/js/bootstrap.js"></script>

<div class="container">

  <div class="form-group">
    <label>Languages</label>
    <input class="form-control autocomplete" placeholder="Enter A" />
  </div>
  
  <div class="form-group">
    <label >Another Field</label>
    <input class="form-control">
  </div>

</div>

修复 #1 - jQuery-UI 样式

只需包含 jquery-ui.css，一切都应该可以在最新支持的 jquery 版本中正常工作。

$(function() {
  var availableTags = [
    "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++",
    "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran",
    "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl",
    "PHP", "Python", "Ruby", "Scala", "Scheme"
  ];
  
  $(".autocomplete").autocomplete({
    source: availableTags
  });
});

<link href="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.css" rel="stylesheet"/>
<link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/css/bootstrap.css" rel="stylesheet"/>

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/js/bootstrap.js"></script>

<div class="container">
  <div class="form-group">
    <label>Languages</label>
    <input class="form-control autocomplete" placeholder="Enter A" />
  </div>
  
  <div class="form-group">
    <label >Another Field</label>
    <input class="form-control">
  </div>
</div>

修复 #2 - Bootstrap 主题

有一个项目为 jQuery-UI 组件创建了 Bootstrap 风格的主题，名为 jquery‑ui‑bootstrap 。只需从那里获取样式表即可完成所有设置。

$(function() {
  var availableTags = [
    "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++",
    "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran",
    "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl",
    "PHP", "Python", "Ruby", "Scala", "Scheme"
  ];
  
  $(".autocomplete").autocomplete({
    source: availableTags
  });
});

<link href="https://cdnjs.cloudflare.com/ajax/libs/jquery-ui-bootstrap/0.5pre/css/custom-theme/jquery-ui-1.10.0.custom.css" rel="stylesheet"/>
<link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/css/bootstrap.css" rel="stylesheet"/>

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/js/bootstrap.js"></script>

<div class="container">
  <div class="form-group">
    <label>Languages</label>
    <input class="form-control autocomplete" placeholder="Enter A" />
  </div>
  
  <div class="form-group">
    <label >Another Field</label>
    <input class="form-control">
  </div>
</div>

修复 #3 - 手动 CSS

如果您只需要 jQuery-UI 库中的 AutoComplete 小部件，那么您应该首先进行自定义构建，这样就不会提取不使用的资源。

之后，您需要自己设计样式。只要看看其他一些应用于jquery的样式 autocomplete.css和 theme.css找出您需要手动替换哪些样式。

您可以使用 bootstrap 的 dropdowns.less寻求灵感。

下面是一个非常适合 Bootstrap 默认主题的 CSS 示例:

.ui-autocomplete {
    position: absolute;
    z-index: 1000;
    cursor: default;
    padding: 0;
    margin-top: 2px;
    list-style: none;
    background-color: #ffffff;
    border: 1px solid #ccc;
    -webkit-border-radius: 5px;
       -moz-border-radius: 5px;
            border-radius: 5px;
    -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
       -moz-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
            box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}
.ui-autocomplete > li {
  padding: 3px 20px;
}
.ui-autocomplete > li.ui-state-focus {
  background-color: #DDD;
}
.ui-helper-hidden-accessible {
  display: none;
}

$(function() {
  var availableTags = [
    "ActionScript", "AppleScript", "Asp", "BASIC", "C", "C++",
    "Clojure", "COBOL", "ColdFusion", "Erlang", "Fortran",
    "Groovy", "Haskell", "Java", "JavaScript", "Lisp", "Perl",
    "PHP", "Python", "Ruby", "Scala", "Scheme"
  ];
  
  $(".autocomplete").autocomplete({
    source: availableTags
  });
});

.ui-autocomplete {
    position: absolute;
    z-index: 1000;
    cursor: default;
    padding: 0;
    margin-top: 2px;
    list-style: none;
    background-color: #ffffff;
    border: 1px solid #ccc
    -webkit-border-radius: 5px;
       -moz-border-radius: 5px;
            border-radius: 5px;
    -webkit-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
       -moz-box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
            box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}
.ui-autocomplete > li {
  padding: 3px 20px;
}
.ui-autocomplete > li.ui-state-focus {
  background-color: #DDD;
}
.ui-helper-hidden-accessible {
  display: none;
}

<link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/css/bootstrap.css" rel="stylesheet"/>

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/js/bootstrap.js"></script>

<div class="container">
  <div class="form-group ui-widget">
    <label>Languages</label>
    <input class="form-control autocomplete" placeholder="Enter A" />
  </div>
  
  <div class="form-group ui-widget">
    <label >Another Field</label>
    <input class="form-control" />
  </div>
</div>

Tip: Since the dropdown menu hides every time you go to inspect the element (i.e. whenever the input loses focus), for easier debugging of the style, find the control with .ui-autocomplete and remove display: none;.
