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">
