实现功能：给年级、班级设置学分，再给年级添加学分时，优先默认学科学分，已有年级下的学分不变；
修改年级学分，班级学分也跟着变化；
修改班级学分不影响其他的学分。
遇到的困难：

1、回车 == 保存 && 取消回车聚焦
function changeCredit(gradeTeachingId,num,isTeaCls,obj) { var theEvent = window.event || gradeTeachingId; var code = theEvent.keyCode || theEvent.which; if (code==13) { //回车键的键值为13 // 验证 var isSubmit=false; var f=false; if(isSubmit){ return; } $(".credit").each(function () { var credit=$(this).val(); if(credit!=""){ if (!/^d+$/.test(credit)){ f=true; layer.tips("格式不正确(最多2位整数)！",$(this), { tipsMore: true, tips: 3 }); return false; } } }); if(f){ isSubmit=false; return; } var credit = $("#credit"+num).val(); // 取消回车聚焦 obj.blur(); $.ajax({ url:"${request.contextPath}/basedata/courseopen/changeGradeCredit", data:{"gradeTeachingId":gradeTeachingId,"credit":credit,"isTeaCls":isTeaCls}, dataType:"json", success:function (data) { // $(obj).unbind("blur"); if(data.success){ layer.msg(data.msg, {offset: ‘t‘,time: 2000}); }else{ layerTipMsg(data.success,"操作失败",data.msg); } } }) } }
2、 
按钮上下+1、-1；取消聚焦就校验值； 以及处理在别的框里输入enter，最上面的框会出现+1的问题
var opoNum=0; $(function () { //数字增加以及减少 $("#subTable").on(‘click‘,‘.form-number > div‘,function(e){ e.preventDefault(); var $num = $(this).siblings(‘.form-control‘); var val = $num.val(); if (!val ) val = 0; var num = parseInt(val); var step = $num.parent(‘.form-number‘).attr(‘data-step‘); if (step === undefined) { step = 1; } else{ step = parseInt(step); } if ($(this).hasClass(‘form-number-add‘)) { num += step; if (num >= 99) num = 99; } else{ num -= step; if (num <= 0) num = 0; } opoNum++; $num.val(num); }); }) //var opoNum=0; $(function () { //数字增加以及减少 $("#xSubTable").on(‘click‘,‘.form-number > div‘,function(e){ e.preventDefault(); var $num = $(this).siblings(‘.form-control‘); var val = $num.val(); if (!val ) val = 0; var num = parseInt(val); var step = $num.parent(‘.form-number‘).attr(‘data-step‘); if (step === undefined) { step = 1; } else{ step = parseInt(step); } if ($(this).hasClass(‘form-number-add‘)) { num += step; if (num >= 99) num = 99; } else{ num -= step; if (num <= 0) num = 0; } opoNum++; $num.val(num); }); })
