layui实现三级联动的方法：首先创建html的页面；然后创建【address.js】文件，内容为“Address.prototype.provinces = function(){...}”；最后通过layui模块实现三级联动即可。
本教程操作环境：windows10系统、layui2.5.6版，Dell G3电脑。
基于layui的三级联动模块
html的页面代码如下：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="renderer" content="webkit">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="format-detection" content="telephone=no">
<link rel="stylesheet" href="../../../layui-v2.1.5/css/layui.css" />
</head>
<body>
<p class="layui-form">
<p class="layui-input-inline">
<select name="province" lay-filter="province" class="province">
<option value="">请选择省</option>
</select>
</p>
<p class="layui-input-inline">
<select name="city" lay-filter="city" disabled>
<option value="">请选择市</option>
</select>
</p>
<p class="layui-input-inline">
<select name="area" lay-filter="area" disabled>
<option value="">请选择县/区</option>
</select>
</p>
</p>
</body>
<script type="text/javascript" src="../../../layui-v2.1.5/layui.js"></script>
<script type="text/javascript" src="address.js"></script>
<script type="text/javascript">
layui.config({
base : "../../../js/" //address.js的路径
}).use([ 'layer', 'jquery', "address" ], function() {
var layer = layui.layer, $ = layui.jquery, address = layui.address();
});
</script>
<html>address.js的代码入下：
ps:需要注意的有： $.get("address.json", function (data) {} 的地址为json地址，地址不对会报异常。
layui.define(["form","jquery"],function(exports){
var form = layui.form,
$ = layui.jquery,
Address = function(){};
Address.prototype.provinces = function() {
//加载省数据
var proHtml = '',that = this;
$.get("address.json", function (data) {
for (var i = 0; i < data.length; i++) {
proHtml += '<option value="' + data[i].code + '">' + data[i].name + '</option>';
}
//初始化省数据
$("select[name=province]").append(proHtml);
form.render();
form.on('select(province)', function (proData) {
$("select[name=area]").html('<option value="">请选择县/区</option>');
var value = proData.value;
if (value > 0) {
that.citys(data[$(this).index() - 1].childs);
} else {
$("select[name=city]").attr("disabled", "disabled");
}
});
})
}
//加载市数据
Address.prototype.citys = function(citys) {
var cityHtml = '<option value="">请选择市</option>',that = this;
for (var i = 0; i < citys.length; i++) {
cityHtml += '<option value="' + citys[i].code + '">' + citys[i].name + '</option>';
}
$("select[name=city]").html(cityHtml).removeAttr("disabled");
form.render();
form.on('select(city)', function (cityData) {
var value = cityData.value;
if (value > 0) {
that.areas(citys[$(this).index() - 1].childs);
} else {
$("select[name=area]").attr("disabled", "disabled");
}
});
}
//加载县/区数据
Address.prototype.areas = function(areas) {
var areaHtml = '<option value="">请选择县/区</option>';
for (var i = 0; i < areas.length; i++) {
areaHtml += '<option value="' + areas[i].code + '">' + areas[i].name + '</option>';
}
$("select[name=area]").html(areaHtml).removeAttr("disabled");
form.render();
}
var address = new Address();
exports("address",function(){
address.provinces();
});
