jquery+css实现下拉列表功能

废话不多说了,直接给大家贴代码了,具体代码如下所述:

<!DOCTYPE html>

<html>

<head>

<meta charset="UTF-8">

<title>fruit</title>

<style type="text/css">

.hide {

display: none;

}

div {

float: left;

width: 100%;

}

.selector-containter {

margin-bottom: 10px;

}

.selector {

width: 200px;

background: #FFF;

border: 1px solid #DDD;

}

.selector-hint {

width: 178px;

border: 1px solid #DDD;

}

.selector-expand {

width: 8px;

border: 1px solid #DDD;

}

.selector-collapse {

width: 8px;

border: 1px solid #DDD;

}

</style>

<script src="jquery-3.2.1.min.js"></script>

<script>

$(document).ready(function() {

//使用on方法,采用事件委派机制,selector-option-container中的内容为后续动态追加

$('.selector').on('click', '.selector-expand', function() {

$(this).parent().children('.selector-option-container').children().remove();

$(this).parent().children('.selector-option-container').append('<div><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></div><div class="selector-option">apricot</div>');

$(this).parent().children('.selector-option-container').append('<div><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></div><div class="selector-option">banana</div>');

$(this).nextAll('.selector-option-container').removeClass('hide');

});

$('.selector').on('click', '.selector-collapse', function() {

$(this).nextAll('.selector-option-container').addClass('hide');

});

$('.selector-t1').on('click', '.selector-option', function() {

$(this).parent().parent().children('.selector-hint').text($(this).text());

$(this).parent().addClass('hide');

});

$('.selector-t1').on('click', '.selector-checkbox', function() {

$(this).parent().parent().parent().children('.selector-hint').text($(this).parent().next().text());

//采用prop方法,对于值为布尔型的属性赋值

$(this).prop('checked', false);

$(this).parent().parent().addClass('hide');

});

});

</script>

</head>

<body>

<div id="titan" class="selector-containter">

<div id="fruit">

<div class="selector">

<div class="selector-hint">select fruit</div>

<div class="selector-expand">+</div>

<div class="selector-collapse">-</div>

<div class="selector-option-container">

</div>

</div>

</div>
