Question

我正在尝试复制您在此图片中可以看到的内容。 enter image description here

我希望能够在框上方输入文本字段，或者直接点击该选项。

最好的方法是什么？是否存在任何相关的引导程序？

Answer 1

Select2 http://select2.github.io可能比选择更好，更活跃。

看到这个比较： http://sitepoint.com/jquery-select-box-components-chosen-vs-select2

我去了Select2（几个月前）因为Chosen在通过IME http://github.com/harvesthq/chosen/issues/2663使用中文字符时遇到了问题。它很有用。

Answer 2

这个简单的代码对我有用

$(document).ready(function(){
$("input").click(function(){
        $(this).next().show();
        $(this).next().hide();
    });

});

<!DOCTYPE html>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Answer 3

选择Js具有我们所需的所有选项。请尝试

  $(document).ready(function () {
      $('select').selectize({
          sortField: 'text'
      });
  });

<html>
<head>

  </select>

</html>

Answer 4

尝试jQuery ui autocomplete。为此，请查看此链接

http://jqueryui.com/autocomplete/#combobox

Answer 5

这对我们大多数人都有效。 Hemanth Palle 给出的答案是最简单的方法，它对我有用，并且不需要JS代码。我发现的唯一问题是，根据W3Schools的说法，Internet Explorer 9和更早版本或Safari不支持The datalist tag。

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<input list="browsers">
<datalist id="browsers">
  <option value="Internet Explorer">
  <option value="Firefox">
  <option value="Chrome">
  <option value="Opera">
  <option value="Safari">
</datalist>  
</body>
</html>

Answer 6

您可以使用select2。这是这份工作的最佳选择。
https://select2.org/dropdown

$(document).ready(function () {
//change selectboxes to selectize mode to be searchable
   $("select").select2();
});

<script src="https://cdn.jsdelivr.net/npm/select2@4.0.13/dist/js/select2.min.js"></script>

</head>
<body>
  <select id="select_page" style="width:200px;" class="operator"> 
         <option value="">Select a Page...</option>
         <option value="alpha">alpha</option> 
         <option value="beta">beta</option>
         <option value="theta">theta</option>
         <option value="omega">omega</option>
  </select>
</body>
</html>

Answer 7

全选项可搜索选择框

这还支持控制按钮键盘，例如ArrowDown ArrowUp和Enter键

function filterFunction(that, event) {
    let container, input, filter, li, input_val;
    container = $(that).closest(".searchable");
    input_val = container.find("input").val().toUpperCase();

    if (["ArrowDown", "ArrowUp", "Enter"].indexOf(event.key) != -1) {
        keyControl(event, container)
    } else {
        li = container.find("ul li");
        li.each(function (i, obj) {
            if ($(this).text().toUpperCase().indexOf(input_val) > -1) {
                $(this).show();
            } else {
                $(this).hide();
            }
        });

        container.find("ul li").removeClass("selected");
        setTimeout(function () {
            container.find("ul li:visible").first().addClass("selected");
        }, 100)
    }
}

function keyControl(e, container) {
    if (e.key == "ArrowDown") {

        if (container.find("ul li").hasClass("selected")) {
            if (container.find("ul li:visible").index(container.find("ul li.selected")) + 1 < container.find("ul li:visible").length) {
                container.find("ul li.selected").removeClass("selected").nextAll().not('[style*="display: none"]').first().addClass("selected");
            }

        } else {
            container.find("ul li:first-child").addClass("selected");
        }

    } else if (e.key == "ArrowUp") {

        if (container.find("ul li:visible").index(container.find("ul li.selected")) > 0) {
            container.find("ul li.selected").removeClass("selected").prevAll().not('[style*="display: none"]').first().addClass("selected");
        }
    } else if (e.key == "Enter") {
        container.find("input").val(container.find("ul li.selected").text()).blur();
        onSelect(container.find("ul li.selected").text())
    }

    container.find("ul li.selected")[0].scrollIntoView({
        behavior: "smooth",
    });
}

function onSelect(val) {
    alert(val)
}

$(".searchable input").focus(function () {
    $(this).closest(".searchable").find("ul").show();
    $(this).closest(".searchable").find("ul li").show();
});
$(".searchable input").blur(function () {
    let that = this;
    setTimeout(function () {
        $(that).closest(".searchable").find("ul").hide();
    }, 300);
});

$(document).on('click', '.searchable ul li', function () {
    $(this).closest(".searchable").find("input").val($(this).text()).blur();
    onSelect($(this).text())
});

$(".searchable ul li").hover(function () {

Answer 8

改为使用数据列表。

<form action="/action_page.php" method="get">
      <input list="browsers" name="browser">
      <datalist id="browsers">
        <option value="Internet Explorer">
        <option value="Firefox">
        <option value="Chrome">
        <option value="Opera">
        <option value="Safari">
      </datalist>
      <input type="submit">
    </form>

不支持的IE 9再回来。 https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_datalist

Answer 9

这是我之前制作的使用jQuery的便捷开源库： https://bitbucket.org/warwick/searchablelist/src/master/ 这是我的VPS上的工作副本：http://developersfound.com/SearchableList/ 该库是高度可定制的，具有可替代的功能，并且可以在同一网页上进行单独的设计希望这会有所帮助

我为引导程序4创建了自己的版本。如果要使用它，可以进行检查。 https://github.com/AmagiTech/amagibootstrapsearchmodalforselect

amagiDropdown(
    {
        elementId: 'commonWords',
        searchButtonInnerHtml: 'Search',
        closeButtonInnerHtml: 'Close',
        title: 'Search and Choose',
        bodyMessage: 'Please firstly search with textbox below later double click the option you choosed.'
    });

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet"/>
<div class="form-group">
                <label for="commonWords">Favorite Word</label>
                <select id="commonWords">
                <option value="1">claim – I claim to be a fast reader, but actually I am average.</option><option value="2" selected>be – Will you be my friend?</option><option value="3">and – You and I will always be friends.</option>
