1、遇到問題及解決javascript
一、觸發事件要先定義jq符號,而後在調用on方法,如html
var $ = layui.$; //新增用戶 $('.userTable #add').on('click', function(){ });
二、layui怎麼打開彈出層的同時,調用後臺方法,讓彈出層顯示後臺返回的頁面?解決方法以下: 這樣就能夠:java
layer.open({ type: 2 ,title:'查看' ,content:'/user/form?id=789a3bf1265e4e00ba0b2cdb57c5f615' });
三、用layui結合jfinal,用form表單action的方式提交,怎麼根據返回值判斷是否操做成功? 用form表單action的方式提交,我沒找到方法,我改成下面的方式:ajax
//監聽提交 form.on('submit(userSubmit)', function(data){ $.post('/user/save',data.field,function(result){ if(result==0){ layer.msg('提交成功!', function(){ window.parent.location.reload(); }); }else{ layer.msg('提交失敗!'); } }); return false; });
2、增刪改查點擊事件及彈出彈出框工具
< script > layui.use('table', function () { var table = layui.table; var $ = layui.$; //監聽工具條 table.on('tool(user)', function (obj) { //列表全部屬性及數據 var data = obj.data; //列表事件(查看) if (obj.event === 'detail') { checkUser(data.id); } //列表事件(刪除) if (obj.event === 'del') { layer.confirm('真的刪除行麼', function (index) { deleteUser(data.id); layer.close(index); } ); } //列表事件(編輯) if (obj.event === 'edit') { editUser(data.id); } }); //新增用戶 $('.userTable #add').on('click', function () { addUser() }); }); //查看用戶 function checkUser(userId) { layer.open( { type : 2, title : '查看', content : '/user/view?id=' + userId, area : ['450px', '450px'], closeBtn : 1 }); } //刪除用戶 function deleteUser(userId) { $.ajax( { type : 'get', url : "/user/delete?id=" + userId, success : function (flag) { if (flag == 0) { layer.msg('刪除成功!', function () { window.parent.location.reload(); }); } else { layer.msg('刪除失敗!'); } } }); } //新增用戶 function addUser() { layer.open( { type : 2, title : '新增', content : '/user/form', area : ['450px', '450px'], closeBtn : 1 }); } //編輯用戶 function editUser(userId) { layer.open( { type : 2, title : '編輯', content : '/user/form?id=' + userId, area : ['450px', '450px'], closeBtn : 1 }); } < / script >
二、新增編輯表單post
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> #@form_layout() <form class="layui-form"> <div class="layui-form-item"> <label class="layui-form-label">用戶名</label> <div class="layui-input-inline"> <input name="user.id" class="layui-input" type="hidden" value="#(user.id??)" /> <input name="user.user_name" class="layui-input" value="#(user.user_name??)" /> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">郵箱</label> <div class="layui-input-inline"> <input name="user.email" class="layui-input" value="#(user.email??)" /> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">手機號</label> <div class="layui-input-inline"> <input name="user.telephone" class="layui-input" value="#(user.telephone??)" /> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">性別</label> <div class="layui-input-inline"> <input name="user.sex" value="1" title="男" type="radio" checked="checked" /> <input name="user.sex" value="2" title="女" type="radio" checked="checked" /> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">崗位</label> <div class="layui-input-inline"> <select name="user.post" lay-filter="aihao"> <option value="1" selected="selected"> 行政 </option> <option value="2" selected="selected"> UI </option> <option value="3" selected="selected"> 測試 </option> <option value="4" selected="selected"> 開發 </option> </select> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">地址</label> <div class="layui-input-inline"> <input name="user.adress" class="layui-input" value="#(user.adress??)" /> </div> </div> <div class="layui-form-item"> <div class="layui-input-block"> <button class="layui-btn" lay-submit="" lay-filter="userSubmit">當即提交</button> <button type="reset" class="layui-btn layui-btn-primary">重置</button> </div> </div> </form> </body> </html>
< script > layui.use('form', function () { var form = layui.form; var $ = layui.$; //監聽提交 form.on('submit(userSubmit)', function (data) { $.post('/user/save', data.field, function (result) { if (result == 0) { layer.msg('提交成功!', function () { window.parent.location.reload(); }); } else { layer.msg('提交失敗!'); } }); return false; }); }); < / script >
三、查看錶單測試
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> #@form_layout() <form class="layui-form"> <div class="layui-form-item"> <label class="layui-form-label">用戶名</label> <label class="layui-form-label">#(user.user_name)</label> </div> <div class="layui-form-item"> <label class="layui-form-label">郵箱</label> <label class="layui-form-label">#(user.email)</label> </div> <div class="layui-form-item"> <label class="layui-form-label">手機號</label> <label class="layui-form-label">#(user.telephone)</label> </div> <div class="layui-form-item"> <label class="layui-form-label">性別</label> #if(user.sex??==1) <label class="layui-form-label">男</label> #end #if(user.sex??==2) <label class="layui-form-label">女</label> #end </div> <div class="layui-form-item"> <label class="layui-form-label">崗位</label> #if(user.post??=="1") <label class="layui-form-label">行政</label> #end #if(user.post??=="2") <label class="layui-form-label">UI</label> #end #if(user.post??=="3") <label class="layui-form-label">測試</label> #end #if(user.post??=="4") <label class="layui-form-label">開發</label> #end </div> <div class="layui-form-item"> <label class="layui-form-label">地址</label> <label class="layui-form-label">#(user.adress)</label> </div> </form><script type="text/javascript"> //<![CDATA[ layui.use('form', function(){ var form = layui.form; }); //]]> </script> </body> </html>
四、後臺java方法ui
/** * 渲染新增,編輯頁面 */ public void form(){ String id = getPara("id"); User user = userService.findUserById(id); if(StrKit.notBlank(id)){ setAttr("user", user); } render("form.html"); } /** * 新增,編輯 */ public void save(){ User user = getModel(User.class); boolean isSuccess = user.saveOrUpdate(); if(isSuccess) { renderJson(0);//保存成功 } else { renderJson(2);//保存失敗 } } /** * 查看 */ public void view(){ String id = getPara("id"); User user = userService.findUserById(id); setAttr("user", user); render("view.html"); } /** * 根據用戶id刪除用戶 */ public void delete() { String id = getPara("id"); boolean flag = userService.deleteById(id); if(flag) { renderJson(0); } else { renderJson(1); } }
3、至此,layui結合jfinal增刪改查完畢url
