我试图建立我的自定义选择,但我是塞。在页面刷新之前,一切都很好。我是一个jQuery乞丐,我在代码库上找到了这个。
$('select').each(function(){
var $this = $(this), numberOfOptions = $(this).children('option').length;
$this.addClass('select-hidden');
$this.wrap('<div class="select"></div>');
$this.after('<div class="select-styled"></div>');
var $styledSelect = $this.next('div.select-styled');
$styledSelect.text($this.children('option').eq(0).text());
var $list = $('<ul />', {
'class': 'select-options'
}).insertAfter($styledSelect);
for (var i = 0; i < numberOfOptions; i++) {
$('<li />', {
text: $this.children('option').eq(i).text(),
rel: $this.children('option').eq(i).val()
}).appendTo($list);
}
var $listItems = $list.children('li');
$styledSelect.click(function(e) {
e.stopPropagation();
$('div.select-styled.active').not(this).each(function(){
$(this).removeClass('active').next('ul.select-options').hide();
});
$(this).toggleClass('active').next('ul.select-options').toggle();
});
$listItems.click(function(e) {
e.stopPropagation();
$styledSelect.text($(this).text()).removeClass('active');
$this.val($(this).attr('rel'));
$list.hide();
//console.log($this.val());
});
$(document).click(function() {
$styledSelect.removeClass('active');
$list.hide();
});
});.select-hidden {
display: none;
visibility: hidden;
padding-right: 10px;
}
.select {
cursor: pointer;
display: inline-block;
position: relative;
font-size: 12px;
color: #005ca5;
height: 40px;
width: 155px;
}
.select-styled {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 1px solid #a2a2a2;
padding: 10px 15px;
border-radius: 20px;
}
.select-styled:after {
content: "";
width: 0;
height: 0;
border: 7px solid transparent;
border-color: #005ca5 transparent transparent transparent;
position: absolute;
top: 16px;
right: 10px;
}
.select-styled.active {
border-bottom-left-radius: 0px;
border-bottom-right-radius: 0px;
}
.select-styled.active:after {
top: 9px;
border-color: transparent transparent #005ca5 transparent;
}
.select-options {
display: none;
position: absolute;
top: 100%;
right: 0;
left: 0;
z-index: 999;
margin: 0;
padding: 0;
list-style: none;
background-color: #fff;
overflow-y: scroll;
max-height: 200px;
border: 1px solid #a2a2a2;
border-top: 0px;
}
.select-options li {
margin: 0;
padding: 12px 0;
text-indent: 15px;
transition: 0.3s;
}
.select-options li:hover {
color: #fff;
background: #005ca5;

我正在使用php,当我选择一个值时,它会保存所选的值。在源代码中,您可以看到默认的select select值,但在我的自定义select中看不到。选择是自动生成的,所以我不能更改HTML.,所以唯一的方法是更改jQuery.

您可以使用localeStorage API来实现这种实现,localeStorage有.setItem()和.getItem()方法,在这些方法中,即使在刷新之后,也可以在应用程序中设置要使用的值。
变动:
var styledText = $this.children('option').eq(0).text();
if(localStorage.getItem($this.attr('name'))) {
styledText = localStorage.getItem($this.attr('name'));
}
$styledSelect.text(styledText);在$listItems.click中
$listItems.click(function(e) {
e.stopPropagation();
$styledSelect.text($(this).text()).removeClass('active');
$this.val($(this).attr('rel'));
$list.hide();
localStorage.setItem($this.attr('name'), $(this).text());
});下面是一个工作的杰斯菲尔德,也是一个代码段,但是它在这里不能工作,因为堆栈溢出段是沙箱化的,不能访问localStorage:
$('select').each(function(){
var $this = $(this), numberOfOptions = $(this).children('option').length;
$this.addClass('select-hidden');
$this.wrap('<div class="select"></div>');
$this.after('<div class="select-styled"></div>');
var $styledSelect = $this.next('div.select-styled');
var styledText = $this.children('option').eq(0).text();
if(localStorage.getItem($this.attr('name'))) {
styledText = localStorage.getItem($this.attr('name'));
}
$styledSelect.text(styledText);
var $list = $('<ul />', {
'class': 'select-options'
}).insertAfter($styledSelect);
for (var i = 0; i < numberOfOptions; i++) {
$('<li />', {
text: $this.children('option').eq(i).text(),
rel: $this.children('option').eq(i).val()
}).appendTo($list);
}
var $listItems = $list.children('li');
$styledSelect.click(function(e) {
e.stopPropagation();
$('div.select-styled.active').not(this).each(function(){
$(this).removeClass('active').next('ul.select-options').hide();
});
$(this).toggleClass('active').next('ul.select-options').toggle();
});
$listItems.click(function(e) {
e.stopPropagation();
$styledSelect.text($(this).text()).removeClass('active');
$this.val($(this).attr('rel'));
$list.hide();
localStorage.setItem($this.attr('name'), $(this).text());
});
$(document).click(function() {
$styledSelect.removeClass('active');
$list.hide();
});
});.select-hidden {
