jquery制作属于自己的select自定义样式_jquery

由于原生select在各个浏览器的样式不统一,特别是在IE67下直接不可以使用样式控制,当PM让你做一个样式的时候,那是相当的痛苦。最好的办法就是使用自定义样式仿select效果。这里写了一个jquery插件,实现自定义的select(阉割了不少原生select的事件,但是最主要的都还在)
需要引用的样式:
 .self-select-wrapper{ 
 position: relative;
 display: inline-block;
 border: 1px solid #d0d0d0;
 width: 250px;
 height:40px;
 font-size: 14px;
}
 
div.self-select-wrapper{
 /*解决IE67 块级元素不支持display:inline-block*/
 *display:inline;
}
 
.self-select-wrapper .self-select-display{
 display: inline-block;
 cursor: pointer;
 width:100%;
 height:40px;
 background: -moz-linear-gradient(top, #fff, #eee);
 background: -o-linear-gradient(top,#fff, #eee);
 background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#fff), to(#eee));
 filter: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#ffffff,endColorStr=#eeeeee);
}
 
.self-select-display .self-select-text{
 padding-left:10px;
 display: inline-block;
 line-height: 40px;
 width: 210px;
}
 
.self-select-display .self-select-arrow-down{
 height:0;
 width:0;
 overflow: hidden;
 font-size: 0;
 line-height: 0;
 display: inline-block;
 vertical-align: middle;
 border-color:#aaa transparent transparent transparent;
 border-style:solid dashed dashed dashed;
 border-width:7px;
}
 
.self-select-wrapper .self-select-ul{
 position: absolute;
 max-height:200px;
 _height:200px;
 border: 1px solid #ccc;
 background-color: #fff;
 top:41px;
 left:0px;
 overflow-y: auto;
 _overflow-y:auto !important;
 padding:0px;
 margin:0px;
 width: 100%;
 z-index:2014;
 display: none;
}
 
.self-select-wrapper .self-select-ul li{
 list-style: none;
}
 
.self-select-ul .self-select-option{
 line-height: 28px;
 cursor: pointer;
 display: block;
 padding-left:10px;
 text-decoration: none;
 color:#000;
}
 
.self-select-ul .self-select-option:hover,
.self-select-ul .current{
 background-color: #eee;
}

js源码:

/**
 * 解决自定义select自定义样式需求
 * select父级元素谨慎使用z-index
 */
(function($){
 var tpl = '
'+ ''+ ''+ ''+ ''+ '
    '+ '
    '; $.fn.selfSelect = function(changeHandler){ var name = $(this).attr('name'); var $selects = $(this); function getSourceData($options) { var text = []; var value = []; $.each($options, function() { text.push($(this).html()); value.push($(this).attr('value')); }); return { text: text, value: value }; } function buildTpl($selfSelect, $select) { var valueArr =[]; var textArr = []; var optionTpl = ''; var $options = $select.find('option'); var sourceData = getSourceData($options); valueArr = sourceData.value; textArr = sourceData.text; $select.hide(); $selfSelect.find('.self-select-text').html(textArr[0]); $.each(textArr, function(seq, text) { optionTpl += '
  • '+text+'
  • '; }); $selfSelect.find('.self-select-ul').html(optionTpl); } function initSelect() { //解决多个select问题 $.each($selects, function(i, selectEl) { var $selfSelect; var guid = Math.floor(Math.random()*100); var $select = $(selectEl); var $parent = $select.parent(); if(!$select.prev().hasClass('self-select-wrapper')) { $select.before(tpl); $select.prev().addClass('select-' + guid); $selfSelect = $parent.find('.select-' + guid); }else { $selfSelect = $select.prev(); } buildTpl($selfSelect, $select); initEvent($selfSelect, $select) }); } function initEvent($selfSelect, $select) { $selfSelect.find('.self-select-display').off('click').on('click', function() { var $selfSelects = $('body').find('.self-select-wrapper'); var isCliked = $(this).hasClass('clicked'); if(isCliked) { $(this).removeClass('clicked'); $selfSelect.find('.self-select-ul').slideUp('fast'); }else { $(this).addClass('clicked'); $selfSelect.find('.self-select-ul').slideDown('fast'); } //防止z-index覆盖问题 $.each($selfSelects, function(i, selectEl) { $(selectEl).css('z-index', 0); }); $selfSelect.css('z-index', 1); }); $selfSelect.find('.self-select-option').on('mousedown', function() { var text = $(this).html(); var value = $(this).attr('value'); $(this).parents('ul').slideUp('fast'); $selfSelect.find('.self-select-display').removeClass('clicked'); $selfSelect.find('.self-select-text').html(text); $(this).addClass('current'); $(this).parent().siblings().children().removeClass('current'); //修改select的值,并触发change事件 $select.val(value); $select.trigger('change', value); }); $(document).on('mousedown', function(e) { if($(e.target).hasClass('self-select-ul') || $(e.target).parent().hasClass('self-select-display')) return; $selfSelect.find('.self-select-display').removeClass('clicked'); $selfSelect.find('.self-select-ul').slideUp('fast'); }); $select.on('change', function(e, val) { changeHandler && changeHandler(val); }); } initSelect(); return this; }; }(jQuery));

    第二个是之前省市联动的插件生成之后,调用自定义select生成的

    自定义sleect优点:

    • 样式完全可控
    • 兼容IE系列浏览器
    • 使用方便,不影响默认的change事件处理

    开发中遇到的问题:
    1.线性渐变
    IE下使用filter: progid:DXImageTransform.Microsoft.Gradient(gradientType=0,startColorStr=#ffffff,endColorStr=#eeeeee);解决线性渐变问题,详解请参考下面的资料。
    2.IE6 A 标签hover问题
    IE6不设置href属性,不会触发:hover样式
    3.IE 67 块级元素display:inline-block
    4.z-index层级问题
    改变处于active状态的自定select的z-index
    5.css实现下三角,IE下透明问题
    设置透明部分的style值为dashed即可。
    border-style:solid dashed dashed dashed;
    如果觉得有用,可以推荐给朋友哦,小编愿意和大家共同进步。

    以上就是jquery制作select自定义样式的方法,希望大家喜欢。
