创建带有搜索选项的选择框

我试图复制你在这张图片中看到的东西。enter image description here

我希望能够在上面的框中输入文本字段或者直接点击该选项。

最好的方法是什么? 是否有任何已经存在的引导程序相关的东西？

Select2 http://select2.github.io may be even better and more active than Chosen.

See this comparison: http://sitepoint.com/jquery-select-box-components-chosen-vs-select2

I went for Select2 (a few months ago) because Chosen had an issue when using Chinese characters via an IME http://github.com/harvesthq/chosen/issues/2663 It works great.

This will done by using jquery. Here is the code

<select class="chosen" style="width:500px;">
<option>Html</option>
<option>Css</option>
<option>Css3</option>
<option>Php</option>
<option>MySql</option>
<option>Javascript</option>
<option>Jquery</option>
<option>Html5</option>
<option>Wordpress</option>
<option>Joomla</option>
<option>Druple</option>
<option>Json</option>
<option>Angular Js</option>
</select>
</div>
<script type="text/javascript">
$(".chosen").chosen();
</script>

This simple code worked for me

<input list="brow">
<datalist id="brow">
<option value="Internet Explorer">
<option value="Firefox">
<option value="Chrome">
<option value="Opera">
<option value="Safari">
</datalist>

Incase you need to use only select tag use Selectize Js. It has all options we require .Please Try It Demo using Selectize Js

This will work for most of us. The answer given by Hemanth Palle is the easiest way to do it, It worked for me and the JS code wasn't necessary. The only problem that I've found is that according to W3Schools, The datalist tag is not supported in Internet Explorer 9 and earlier versions, or in Safari.

<!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>

You can achieve this without JavaScript using pure HTML Datalist element:

<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>

Here's a handy open source library I made earlier that uses jQuery: https://bitbucket.org/warwick/searchablelist/src/master/ And here is a working copy on my VPS: http://developersfound.com/SearchableList/ The library is highly customisable with overridable behavours and can have seperate designs on the same web page Hope this helps

Full option searchable select box

This also supports Control buttons keyboards such as ArrowDown ArrowUp and Enter keys

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) {

I did my own version for bootstrap 4. If you want to use it u can check. https://github.com/AmagiTech/amagibootstrapsearchmodalforselect

amagiDropdown(
{
elementId: 'commonWords',

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

<div class="form-group">

<option value="1">claim – I claim to be a fast reader, but actually I am average.</option>

If you want to reach your goal with only vanilla js, then I strongly recommend to use Tom Select library which is forked from Selectize.js and then decoupled from jQuery.

    new TomSelect("#select-state",{
create: false,
sortField: {
field: "text",
direction: "asc"
}
});

If you want to reach your goal with a few updates in your code just do the following

<script>
$(document).ready(function () {
$('select').selectize({
sortField: 'text'

});


// to clear the selected value.
$('form').find('.selectized').each(function(index, element) { element.selectize && element.selectize.clear() })

To anyone still finding this, you'll also want to consider Select2, which does all this easily. https://select2.org/getting-started/installation

This was good solution but, only problem is, its inefficient for large data

Here is a simple solution without any plugins. Only html and some jquery. You can save following code sample as a html file and test it.

function myFunction() {
$("#dropdown-values").addClass("show");
}


$(document).click(function(e) {
if( e.target.id != 'myInput') {
$("#dropdown-values").removeClass("show");
}
});


function filterFunction() {
var input, filter, a, i;
filter = $("#myInput").val().toUpperCase();
div = document.getElementById("myDropdown");
a = div.getElementsByTagName("a");
for (i = 0; i < a.length; i++) {
txtValue = a[i].textContent || a[i].innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
a[i].style.display = "";
} else {
a[i].style.display = "none";
}
}
}


function setValueOfInput(e) {
$("#myInput").val(e.innerHTML);
}
.dropdown-content {
position: absolute;
background-color: #f6f6f6;
overflow: auto;
}


.dropdown-content a {
color: black;
padding: 10px 16px;
text-decoration: none;
display: block;
}


.dropdown a:hover {background-color: #ddd;}


.show {display: block !important;}


.dropdown-values{
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>


<h2>Dropdown with search</h2>


<div class="dropdown">
<div id="myDropdown" class="dropdown-content">
<input type="text" placeholder="Search.." id="myInput" onkeyup="filterFunction()" onclick="myFunction()">
<div id="dropdown-values" class="dropdown-values">
<a onclick="setValueOfInput(this)">option 1</a>
<a onclick="setValueOfInput(this)">option 2</a>
<a onclick="setValueOfInput(this)">option 3</a>
<a onclick="setValueOfInput(this)">option 4</a>
<a onclick="setValueOfInput(this)">option 5</a>
</div>
