一、引入js和css
二、使用
1、表单
2、文件上传（带上传进度）
定义上传的按钮
<div class="layui-form-item projAuto"> <label class="layui-form-label">开发建设用地面积（s）：label> <div class="layui-input-block"> <button id="btnUploadSocialHousingRange" type="button" class="layui-btn layui-btn-sm btnUpload"> <i class="layui-icon">i> 选择CAD文件 button> <input type="hidden" class="uploadFileValue" name="socialHousingRange"/> <span class="uploadFileName layui-text">span> <span class="uploadSuccessText ml15 none oh"> <span class="layui-icon" style="color: #007166;">စspan> span> <span class="progressText">span> div> div>
初始化上传的方法
function initUploadSocialHousingRangeInstance(){ var uploadSocialHousingRangeInstance = upload.render({ elem : "#btnUploadSocialHousingRange", //auto : false, field : "file", accept : "file", //acceptMime : "image/*", exts : "dwg", data : {userID : 1}, url : webApi.map.rest.cadAnalysisUrl, choose : function(obj){ var thisItem = $(this.item); obj.preview(function(index, file, result){ //console.log("choose filename = " + JSON.stringify(file.name)); $(thisItem).siblings(".uploadFileName").html(file.name); }); $(this.item).siblings(".progressText").html(""); $(this.item).siblings(".uploadFileValue").val(""); $(this.item).siblings(".uploadSuccessText").hide(); $(":input[name='develop_area_1']").val(""); $(":input[name='develop_area_2']").val(""); $(":input[name='develop_area_3']").val(""); layer.msg("文件上传中，请等待…", { icon : 16, shade : 0.05 }); }, progress : function(n, elem){ $(this.item).siblings(".progressText").html(n + "%"); }, done : function(res, index, upload){ layer.closeAll(); //console.log("res = " + JSON.stringify(res)); if(res.DWGRESULT.COORD){ $(this.item).siblings(".uploadFileValue").val(res.DWGRESULT.COORD); $(this.item).siblings(".uploadSuccessText").show(); }else{ layer.msg("文件解析失败，请重试"); } }, error : function(index, upload){ layer.closeAll(); layer.msg("文件上传失败，请重试"); } }); };
执行初始化方法
$(function(){ initUploadSocialHousingRangeInstance() });
3、LayUI下拉框（LayUI Select）不显示
<div> <form class="layui-form" autocomplete="off"> <div class="layui-form-item"> <label class="layui-form-label">公配设施类型：label> <div class="layui-input-inline"> <select name="publicFacilitiesType" lay-verfify="required" lay-search lay-filter="publicFacilitiesTypeFilter"> <option value="幼儿园">幼儿园option> <option value="小学">小学option> <option value="中学">中学option> select> div> div> <div class="layui-form-item"> <div class="tac"> <button class="layui-btn layui-btn-normal" id="btnAnalysis" lay-submit lay-filter="formAnalysis">智能分析button> <button class="layui-btn layui-btn-primary" type="button" onclick="resetForm()">重置button> div> div> form> div>
注意：上面html代码虽然定义的select元素，但还是不能正常显示的，需要在加载完后使用form.render();重新渲染。
$(function(){ form.on("submit(formAnalysis)", function(data){ initData(data); return false; }); form.on("select(publicFacilitiesTypeFilter)", function(data){ //option改变时的操作 //publicFacilitiesTypeChange(data.value); //console.log("data.elem" + data.elem); //console.log("data.elem" + data.value); return false; }); form.render(); });
重置：
function resetForm(){ layer.confirm("您确定要重置吗？", { btn : ["确定", "取消"] }, function(){ window.location = window.location; }, function(){ //layer.msg("取消"); }); };
4、LayUI自定义校验规则：
<div class="layui-form-item"> <label id="populationText" class="layui-form-label">服务人口数：label> <div class="layui-input-inline"> <input type="text" name="population" class="layui-input" lay-verify="required|numberEmpty"/> div> <div id="populationTextTip" class="layui-form-mid layui-word-aux">（万人）div> div>
上面有一个自定义校验规则：numberEmpty
var layer = layui.layer; var form = layui.form; $(function(){ form.verify({ numberEmpty : function(value, item){ if(!isEmpty(value)){ if(!isNumber(value)){ return "只能填写数字"; } } } }); //form.render();//不清楚还要不要这个 });
5、Layer提示封装
var layer = layui.layer; L = {}; L.msg = function(msg){ return layer.msg(msg); }; L.fail = function(msg){ return layer.alert(msg, {icon: 5, shade: 0.5}); }; L.failMsg = function(msg){ return layer.msg(msg, {icon: 5}); }; L.ok = function(msg){ return layer.alert(msg, {icon: 6, shade: 0.5}); }; L.okMsg = function(msg){ return layer.msg(msg, {icon: 6}); }; L.alert = function(msg){ return layer.alert(msg); }; L.load = function(msg){ return layer.msg((msg || "数据处理中，请等待…"), { icon : 16, shade : 0.2, time: 0//不关闭 }); }; L.confirm = function(msg){ return layer.msg((msg || "数据处理中，请等待…"), { icon : 16, shade : 0.2, time: 0//不关闭 }); }; /* 使用： aaa = function(){ alert("bbbcc"); }; L.confirm("你确定？", aaa); */ L.confirm = function(msg, callbackFunction){ return layer.confirm((msg || "您确定要操作吗？"), { btn: ["确定", "关闭"] //按钮 }, function(index, layero){ callbackFunction(); layer.close(index); }, function(index, layero){ layer.close(index); }); };
6、Layer处理Ajax请求（遮罩层）
function getFunction(projNo){ var index = L.load("正在处理，请等待…"); $.ajax({ url : "../xxxAction", type : "post", dataType : "json", data : { projNo : projNo }, complete : function(XMLHttpRequest, textStatus){ layer.close(index); }, error : function(XMLHttpRequest, textStatus, errorThrown){ layer.close(index); if("error" == textStatus){ layer.msg("失败，请重试", {icon: 5}); }else{ layer.msg("请求失败，textStatus="+textStatus, {icon: 5}); } }, success : function(data){ //console.log("data=" + JSON.stringify(data)); if(data && data.result){ //成功 }else{ layer.msg(data.msg, {icon: 5}); } } }); };
7、layui-form-label 长度修改
.layui-form-label{width: 250px;} .layui-form-label-small{width: 90px;padding: 9px 5px;}
