1. Sorting verification
html code
<div class="layui-form-item"> <label class="layui-form-label">排序</label> <div class="layui-input-block"> <input type="number" name="sort" autocomplete="off" min="0" max="99999" lay-verify="sort" class="layui-input"> </div> </div>
type="number" After that, the effect as shown above will appear behind the text box, and Only numbers and decimal points can be entered
js code
layui.use([ "form", "layer" ], function() { var form = layui.form; var layer = layui.layer; //表单验证 form.render();//这句一定要加,占坑 form.verify({ sort:[/^$|^[0-9]{0,5}$/, '只能是数字且范围0~99999!']//这个就是上面的排序lay-verify="sort" ,remark: function (value){ if(value.length > 200){ return '长度大于200!请重新输入'; } } }); });
2. Amount verification
The effect is the same as sorting
<div class="layui-form-item"> <label class="layui-form-label">余额(元)</label> <div class="layui-input-block"> <input type="number" name="balance" id="balance" lay-verify="money" autocomplete="off" placeholder="单位:元" class="layui-input" > </div> </div>
layui.use([ "form", "layer", "laydate" ], function() { laydate = layui.laydate; form = layui.form; layer = layui.layer;// 表单验证 form.render(); form.verify({ lenth50 : function(value) { if (value.length > 50) { return '长度大于50!请重新输入'; } }, lenth400 : function(value) { if (value.length > 400) { return '长度大于400!请重新输入'; } }, money : function(value) { if (value.length > 0) { var reg = /(^[0-9]([0-9]+)?(\.[0-9]+)$)|(^(0){1}$)|(^([0-9]+)?$)/; if (!reg.test(value)) { return '输入格式有误'; } } if (value.length > 50) { return '长度大于50!请重新输入'; } } }); //下面这段代码主要是用于强制清除当用户输入0开头的数字,比如0000,02323,匹配到的话就为0 //如果要在layui里面 写js事件之类的代码就一定要放在use组件模块里面,这是其中一个坑! $('#balance').bind('input propertychange', function() { var balance = $("#balance").val(); var zero = /^(0){2,}$|^(0)([0-9])?$/; if (zero.test(balance)) { $('#balance').val(0); } }); });
