layui已經(jīng)提供了一整套的UI布局及相關(guān)組件,并且有相當(dāng)完善的api文檔,本文重點(diǎn)在于thymeleaf中如何使用layui,包括公用部分的提取,而非簡(jiǎn)單的layui的用法。
先上兩個(gè)效果圖


一、思路
1.像傳統(tǒng)的一樣建文件頭和尾(但是又和傳統(tǒng)的寫法不同,見下面代碼)
2.定義公用js--common.js
3.定義公用css--用來重寫一些樣式或者自定義樣式
4.編寫列表頁(yè)
5.編寫表單頁(yè)
二、文件頭和尾
頭部引入css,尾部引入js,定義兩個(gè)模板(一個(gè)也可以,里面的碎片分開寫,我喜歡寫兩個(gè)分別引入),注意th:fragment,fragment即碎片,可以在模板任何位置引入,此處為分別定義名為header和js_footer的碎片,以供后面引用
樣式文件 link.html
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<div th:fragment="header">
<meta charset="utf-8"/>
<meta http-equiv="X-UA-Compatible" content="IE=edge"/>
<!-- Tell the browser to be responsive to screen width -->
<meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport"/>
<link rel="stylesheet" th:href="@{/js/layui/css/layui.css}"/>
<link rel="stylesheet" th:href="@{/css/common.css}"/>
</div>
</html>
js文件 script.html
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<div th:fragment="js_footer">
<script th:src="@{/js/layui/layui.all.js}"></script>
<script th:src="@{/js/common/common.js}"></script>
<!-- 讓IE8/9支持媒體查詢,從而兼容柵格 -->
<!--[if lt IE 9]>
<script src="https://cdn.staticfile.org/html5shiv/r29/html5.min.js"></script>
<script src="https://cdn.staticfile.org/respond.js/1.4.2/respond.min.js"></script>
<![endif]-->
</div>
<script>
var basePath='http://www.baidu.com';
</script>
</html>
三、公用js
該文件包含幾個(gè)方法:
1.initTable 初始化帶分頁(yè)的table,注意其中的request屬性,可以配置和你后臺(tái)Page對(duì)象對(duì)應(yīng)的屬性,具體可以參考layui官方文檔
2.searchTable table的搜索功能,調(diào)用layui table模塊的的重載功能,參數(shù)組建思路:獲取序列化的表單,組裝成json對(duì)象
3.upload 文件上傳
4.openFrame 打開彈出層,基于最頂層彈出
var Common = function () {
var initTable = function (ele, url, cols, table, doneCallBack) {
return table.render({
elem: ele
, url: url
, method: 'POST'
, cellMinWidth: 80 //全局定義常規(guī)單元格的最小寬度,layui 2.2.1 新增
, cols: cols
, page: {
limits: [10, 20, 50, 100]
},
request: {
pageName: 'current',
limitName: 'size'
},
done: function (res, curr, count) {
if (typeof(doneCallBack) === "function") {
doneCallBack(res);
}
}
});
};
var searchTable = function (formId, tableIns) {
var queryParams = getParams(formId);
tableIns.reload({
where: {condition: queryParams},
page: {
curr: 1 //重新從第 1 頁(yè)開始
}
});
};
var getParams = function (formId) {
var $ = layui.jquery;
var _params = {};
$.each($('#' + formId).serializeArray(), function (i, field) {
if (null != field.value && "" != field.value) {
_params[field.name] = field.value;
}
});
return _params;
};
var upload = function (eleId, layUpload, done, error, accept, exts) {
layUpload.render({
elem: eleId //綁定元素
, url: '/upload/' //上傳接口
, accept: accept === undefined ? 'file' : accept
, exts: exts === undefined ? 'jpg|png|gif|bmp|jpeg' : exts
, done: function (res) {
//上傳完畢回調(diào)
if (typeof (done) === 'function') {
done(res)
}
}
, error: function () {
//請(qǐng)求異?;卣{(diào)
if (typeof (error) === 'function') {
error()
}
}
});
};
var openFrame = function (url, title, width, height) {
width = width === undefined ? '900px' : width;
height = height === undefined ? '500px' : height;
return top.layer.open({
area: [width, height],
type: 2,
title: title,
content: url //這里content是一個(gè)URL,如果你不想讓iframe出現(xiàn)滾動(dòng)條,你還可以content: ['http://sentsin.com', 'no']
});
};
return {
initTable: function (ele, url, cols, table, doneCallBack) {
return initTable(ele, url, cols, table, doneCallBack);
},
searchTable: function (formId, table) {
searchTable(formId, table);
},
uploadFile: function (eleId, layUpload, done, error, accept, exts) {
upload(eleId, layUpload, done, error, accept, exts);
},
openFrame: function (url, title, width, height) {
return openFrame(url, title, width, height);
}
}
}();
四、公用css
這個(gè)可以根據(jù)個(gè)人喜好或者項(xiàng)目實(shí)際情況自己定義
.form-body{
margin-top: 4%
}
.layui-input-inline{
width: 350px !important;
}
五、列表頁(yè)
整個(gè)html除了頭部的引入,整體分為三部分:
1.上面form為搜索內(nèi)容部分
2.中間一個(gè)table為主窗口
3.注意一個(gè)id="toolBars"的js,為工具條,用于追加在每一列的后面
4.可以看到下面頁(yè)面初始化等都調(diào)用了Common.js中的對(duì)應(yīng)方法

<script>
cols=[[
{checkbox: true, fixed: true}
,{field:'username', title: '用戶名'} //width 支持:數(shù)字、百分比和不填寫。你還可以通過 minWidth 參數(shù)局部定義當(dāng)前單元格的最小寬度,layui 2.2.1 新增

,{field:'op',title: '操作', align:'center', toolbar: '#toolBars'} //這里的toolbar值是模板元素的選擇器
]];
layui.use('table', function(){
var table = layui.table,$ = layui.jquery;
table.on('tool(userFilter)', function(obj){
var data = obj.data; //獲得當(dāng)前行數(shù)據(jù)
var layEvent = obj.event; //獲得 lay-event 對(duì)應(yīng)的值(也可以是表頭的 event 參數(shù)對(duì)應(yīng)的值)
if(layEvent === 'detail'){ //查看
//TODO detail
} else if(layEvent === 'del'){ //刪除
top.layer.confirm('真的刪除行么', function(index){
//TODO do delete

Common.openFrame('/sys/user/to-edit?id=' + data.id,'修改用戶信息');
}
});
var initTable = Common.initTable('#userTable','/sys/user/query-page',cols,table);
$('#searchBtn').on('click',function () {
Common.searchTable('searchForm',initTable);
})
});
</script>
</body>
</html>
六、表單頁(yè)
列表出來之后表單就更簡(jiǎn)單了,只需要去layui官網(wǎng)找個(gè)表單,根據(jù)自己的實(shí)際情況布局即可,特別說明的是校驗(yàn),即verify.js,用于自己對(duì)驗(yàn)證方法的擴(kuò)展
form.html

</div>
<div class="layui-form-item layui-col-md4 layui-col-md-offset2">

<div class="layui-input-inline">

<div class="layui-input-inline">
<button type="button" class="layui-btn" id="test1">

</div>
</div>
</div>

<script>
layui.use('form', function () {
var form = layui.form, upload = layui.upload;
form.render();
Common.uploadFile('#test1', upload, function (data) {
console.log(data);
});
//監(jiān)聽提交
form.on('submit(formDemo)', function (data) {
layer.msg(JSON.stringify(data.field));
//TODO ajax提交表單
return false;
});
});
</script>
</body>
</html>
verify.js
layui.use('form', function () {
var form = layui.form;
//自定義驗(yàn)證規(guī)則
form.verify({
username: function (value) {
if (value.length < 6 || value.length > 12) {
return '請(qǐng)輸入6到12位的用戶名';
}
}, password: function (value) {
if (value.length < 4) {
return '內(nèi)容請(qǐng)輸入至少4個(gè)字符';
}
}
, phone: [/^1[3|4|5|7|8]\d{9}$/, '手機(jī)必須11位,只能是數(shù)字!']
, email: [/^[a-z0-9._%-]+@([a-z0-9-]+\.)+[a-z]{2,4}$|^1[3|4|5|7|8]\d{9}$/, '郵箱格式不對(duì)']
});
})
其他小技巧:
idea使用thymeleaf模板時(shí),頁(yè)面取值總提示無法解析變量,但是又不影響實(shí)際應(yīng)用,據(jù)說idea2017.3已經(jīng)解決了,但是我現(xiàn)在用的2017.2,沒有更新,但是同樣可以解決。錯(cuò)誤提示如圖

解決方法也很簡(jiǎn)單:File--settings--Editor--Inspections--Thymeleaf,去掉第一個(gè)校驗(yàn)即可。
