我正试图建立我的自定义选择,但我被卡住了。一切都很好,直到页面刷新。我是一个jQuery初学者,我在codepen上发现了这个。
$('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;

z-index: 999;
margin: 0;

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 {

}

我是用php工作的,当我选择一个值时,它保存了所选的值。在源码中,你可以看到默认选择中的选择值,但在我的自定义选择中没有。选择是自动生成的,所以我不能改变HTML。所以唯一的办法就是改变jQuery...
你可以使用 localeStorage API 对于这样的实现,localeStorage有 .setItem()
和 .getItem()
方法,您可以在其中设置即使在刷新后也要在整个应用程序中使用的值。
变化。
var styledText = $this.children('option').eq(0).text();
if(localStorage.getItem($this.attr('name'))) {
styledText = localStorage.getItem($this.attr('name'));
}
$styledSelect.text(styledText);
以及在 $listItems.click
:
$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());
});
这里有一个工作方案 jsfildde,也是一个代码段,但在这里是行不通的,因为stackoverflow的代码段是沙盒式的,不能访问localStorage。
