Twitter的typeahead.js建议没有样式(没有边框,透明背景等)

Question

我正在使用twitter的typeahead.js 0.9.3,似乎我的建议根本没有风格.

我明白了:

而不是像这样的东西:(取自示例页面)

JavaScript启用typeahead:

$('.search-typeahead').typeahead({
    name: 'videos',
    remote: {
        url: '/api/v1/internal/videos/typeahead?text=%QUERY'
    }
});

HTML输入元素:

<input type="text" value="" id="search_keywords" class="no-clear search-typeahead"/>

补充说明:

我正在使用的网站有jQuery 1.10.1,并且不使用twitter bootstrap.有一堆CSS我没有写,因此我不熟悉我害怕干扰,但似乎插件添加自己的样式(没有附带的.css文件)所以不应该理论上覆盖的东西？我很困惑为什么我的样式工作,但插件添加的那些没有,导致建议透明背景,没有边框等.

Answer 1

所以看看我现在看到的文档:

默认情况下,typeahead.js创建的下拉菜单看起来很丑陋,您需要对其进行样式设置以确保它适合您网页的主题.

因此,我的解决方案是从我希望复制的示例中复制样式:

.tt-query, /* UPDATE: newer versions use tt-input instead of tt-query */
.tt-hint {
    width: 396px;
    height: 30px;
    padding: 8px 12px;
    font-size: 24px;
    line-height: 30px;
    border: 2px solid #ccc;
    border-radius: 8px;
    outline: none;
}

.tt-query { /* UPDATE: newer versions use tt-input instead of tt-query */
    box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

.tt-hint {
    color: #999;
}

.tt-menu { /* UPDATE: newer versions use tt-menu instead of tt-dropdown-menu */
    width: 422px;
    margin-top: 12px;
    padding: 8px 0;
    background-color: #fff;
    border: 1px solid #ccc;
    border: 1px solid rgba(0, 0, 0, 0.2);
    border-radius: 8px;
    box-shadow: 0 5px 10px rgba(0,0,0,.2);
}

.tt-suggestion {
    padding: 3px 20px;
    font-size: 18px;
    line-height: 24px;
}

.tt-suggestion.tt-is-under-cursor { /* UPDATE: newer versions use .tt-suggestion.tt-cursor */
    color: #fff;
    background-color: #0097cf;

}

.tt-suggestion p {
    margin: 0;
}

Answer 2

因此,以下样式将为您提供这种外观和感觉.它基于我从官方Typeahead示例网站中提取的CSS.

CSS:

.tt-query {
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
     -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
          box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

.tt-hint {
  color: #999
}

.tt-menu {    /* used to be tt-dropdown-menu in older versions */
  width: 422px;
  margin-top: 4px;
  padding: 4px 0;
  background-color: #fff;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, 0.2);
  -webkit-border-radius: 4px;
     -moz-border-radius: 4px;
          border-radius: 4px;
  -webkit-box-shadow: 0 5px 10px rgba(0,0,0,.2);
     -moz-box-shadow: 0 5px 10px rgba(0,0,0,.2);
          box-shadow: 0 5px 10px rgba(0,0,0,.2);
}

.tt-suggestion {
  padding: 3px 20px;
  line-height: 24px;
}

.tt-suggestion.tt-cursor,.tt-suggestion:hover {
  color: #fff;
  background-color: #0097cf;

}

.tt-suggestion p {
  margin: 0;
}

这假设您的输入将具有form-control该类.对于我的例子,它是这样的:

<input class="typeahead form-control" type="text" placeholder="States of USA">

其他的看起来不太好,这个看起来最像Bootstrap.

Answer 4

Typeahead已更改了一些类名,上面的示例现在不正确.

例如:

• 而不是.tt-suggestion.tt-is-under-cursor 使用.tt-suggestion:hover
• 而不是.tt-dropdown-menu,使用.tt-menu

如果您想借用示例页面中的样式,可以在此处查看其样式表:

.typeahead,
.tt-query,
.tt-hint {
  width: 396px;
  height: 30px;
  padding: 8px 12px;
  font-size: 24px;
  line-height: 30px;
  border: 2px solid #ccc;
  -webkit-border-radius: 8px;
     -moz-border-radius: 8px;
          border-radius: 8px;
  outline: none;
}

.typeahead {
  background-color: #fff;
}

.typeahead:focus {
  border: 2px solid #0097cf;
}

.tt-query {
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
     -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
          box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

.tt-hint {
  color: #999
}

.tt-menu {
  width: 422px;
  margin: 12px 0;
  padding: 8px 0;
  background-color: #fff;
  border: 1px solid #ccc;
  border: 1px solid rgba(0, 0, 0, 0.2);
  -webkit-border-radius: 8px;
     -moz-border-radius: 8px;
          border-radius: 8px;
  -webkit-box-shadow: 0 5px 10px rgba(0,0,0,.2);
     -moz-box-shadow: 0 5px 10px rgba(0,0,0,.2);
          box-shadow: 0 5px 10px rgba(0,0,0,.2);
}

.tt-suggestion {
  padding: 3px 20px;
  font-size: 18px;
  line-height: 24px;
}

.tt-suggestion:hover {
  cursor: pointer;
  color: #fff;
  background-color: #0097cf;
}

.tt-suggestion.tt-cursor {
  color: #fff;
  background-color: #0097cf;

}

.tt-suggestion p {
  margin: 0;
}

这是Stack Snippets中的演示

var substringMatcher = function(strs) {
  return function findMatches(q, cb) {
    var matches, substringRegex;
 
    // an array that will be populated with substring matches
    matches = [];
 
    // regex used to determine if a string contains the substring `q`
    substrRegex = new RegExp(q, 'i');
 
    // iterate through the pool of strings and for any string that
    // contains the substring `q`, add it to the `matches` array
    $.each(strs, function(i, str) {
      if (substrRegex.test(str)) {
        matches.push(str);
      }
    });
 
    cb(matches);
  };
};
 
var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
  'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',
  'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana',

  'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'
];
 
$('.typeahead').typeahead({
  hint: true,
  highlight: true,
  minLength: 1
},
{
  name: 'states',
  source: substringMatcher(states)
});

.typeahead,
.tt-query,
.tt-hint {
  width: 396px;
  height: 30px;
  padding: 8px 12px;
  font-size: 24px;

  -webkit-border-radius: 8px;
     -moz-border-radius: 8px;
          border-radius: 8px;
  outline: none;
}

.typeahead {
  background-color: #fff;
}

.typeahead:focus {
  border: 2px solid #0097cf;
}

.tt-query {
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
     -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
          box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

.tt-hint {

}

.tt-suggestion {
  padding: 3px 20px;

  line-height: 24px;
}

.tt-suggestion:hover {

}

.tt-suggestion.tt-cursor {
  color: #fff;
  background-color: #0097cf;

}

.tt-suggestion p {
  margin: 0;
}

这是适合我的代码:

.twitter-typeahead .tt-query,
.twitter-typeahead .tt-hint {
    margin-bottom: 0;
}
.tt-hint {
    display: block;
    width: 100%;
    padding: 8px 12px;
    font-size: 14px;
    line-height: 1.428571429;
    color: #999;
    vertical-align: middle;
    background-color: #ffffff;
    border: 1px solid #cccccc;
    border-radius: 4px;
    -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
          box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
    -webkit-transition: border-color ease-in-out 0.15s, box-shadow ease-in-out 0.15s;
          transition: border-color ease-in-out 0.15s, box-shadow ease-in-out 0.15s;
}
.tt-dropdown-menu {
    min-width: 160px;
    margin-top: 2px;
    padding: 5px 0;
    background-color: #ffffff;
    border: 1px solid #cccccc;
    border: 1px solid rgba(0, 0, 0, 0.15);
    border-radius: 4px;
    -webkit-box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
          box-shadow: 0 6px 12px rgba(0, 0, 0, 0.175);
    background-clip: padding-box;

}
.tt-suggestion {
    display: block;
    padding: 3px 20px;
}
.tt-suggestion.tt-is-under-cursor {
    color: #fff;
    background-color: #dfdfdf;
}
.tt-suggestion.tt-is-under-cursor a {
    color: #fff;
}
.tt-suggestion p {
    margin: 0;
}
