freemarker map判断空值

回车键提交： $("body").keydown(function (event) {       var event = event || window.event; //兼容火狐          if (event.keyCode == "13") {//keyCode=13是回车键              $('#loginAction').click();       

Date.prototype.format = function (pattern) {var format = pattern || "yyyy-MM-dd HH:mm:ss";var o = {"M+": this.getMonth() + 1,"d+": this.getDate(),"H+": this.getHours(),"m+": this.getMinute

原因是selectpicker 没能完整的初始化，先初始化： $('#edit_schoolId').selectpicker();jq 代码:            var schoolId = $("#schoolId_each").val();            if (schoolId) {                var str = schoolId.split("...

绑定:    $("#sendMessage").on("click",function(){        var mobilePhone =  $.trim($("#mobileNo").val());        if (mobilePhone.length             layer.alert("请输入手机号~", {icon: 2});
