這篇文章主要給大家介紹了關(guān)于layui使用及簡單的三級聯(lián)動的實現(xiàn)方法，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨著小編來一起學習學習吧
LayUI的使用
1 、引用
1、下載：官網(wǎng)：https://www.layui.com
2、使用方法：直接將解壓好的壓縮包拖拽到項目內(nèi)
將以下導入到html中：
<link rel="stylesheet" href="/自己的地址/./layui/css/layui.css" rel="external nofollow" media="all">
<script type="text/javascript" src="../自己的地址+layui/layui.js"></script>
2、輸出：hello world
<script type="text/javascript" src="./jquery-3.0.0/jquery-3.0.0.min.js"></script>
<!-- 直接將解壓的文件輔助到項目 然后導入layui.css和layui.js -->
<script type="text/javascript" src="../day/layui/css/layui.css"></script>
<script type="text/javascript" src="../day/layui/layui.js"></script>
<!--提示：如果是采用非模塊化方式（最下面有講解），此處可換成：./layui/layui.all.js -->
<script type="text/javascript" src="./layui/layui.all.js"></script>
</head>
<body>
<script>
// layui.use(['layer', 'form'], function(){
// var layer = layui.layer
// ,form = layui.form;
// layer.msg('Hello World');
// });
$(function(){
layer.msg('Hello World');
})
</script>
</body>
</html>
3、基于layui三級聯(lián)動
html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<title>基于 Layui form 組件的省市區(qū)聯(lián)動選擇的實現(xiàn)</title>
<script type="text/javascript" src="./jquery-3.0.0/jquery-3.0.0.min.js"></script>
<link rel="stylesheet" href="layui/css/layui.css" />
<script src="layui/css/layui.css"></script>
<script type="text/javascript" src="layui/layui.js"></script>
<script type="text/javascript" src="./data.js"></script>

</head>
<body>
<div style="width:800px;margin:50px auto;">

$.each(threeSelectData, function (k, v) {
appendOptionTo($form.find('select[name=' + config.s1 + ']'), k, v.val, config.v1);

});
function cityEvent(data) {
$form.find('select[name=' + config.s2 + ']').html("");
config.v1 = data.value ? data.value : config.v1;
$.each(threeSelectData, function (k, v) {
if (v.val == config.v1) {

form.on('select(' + config.s3 + ')', function (data) { });
}
function appendOptionTo($o, k, v, d) {
var $opt = $("<option>").text(k).val(v);
if (v == d) { $opt.attr("selected", "selected") }
$opt.appendTo($o);
}
}
