　　坑了我两天的代码，新手入职一个月，没学过js，平时都是靠度娘边学边做，这两天给了我一个关于dtree的任务，首先了解dtree花费了我一天时间，为了动态生成这个树结构，我花费了好久时间，一直在琢磨，终于能够生成这个树结构；随后为了完成删除父节点以及子节点，想了好多方法，写了好多demo就是不成功，最后经过别人指点

bubuko.com,布布扣
alert($(‘#content‘+knowledgeId).parent(‘.node‘).parent(‘.dTreeNode‘).next(‘.clip‘).find(‘input[name="ids"]‘).val());

终于拿到了，父节点以及子节点所有的id值。

　　之后为了做一个验证(jquery.validate)，之前就做过验证并且成功了，这次用很快速度完成了验证的js代码

bubuko.com,布布扣 
function addOrUpExa(flag) {
    $("#baseform").validate({
        onkeyup:false,
        onsubmit:true,
        rules:{
            "specielId" : {
                min : 1,
            },
            "subject" : {
                subjectxxx : true,
            },
            "examcentreName" : {
                required: true,
            }
        },
        messages:{
            "specielId" : {
                min : "请选择专题",
            },
            "subject" : {
                subjectxxx : "请选择科目",
            },
            "examcentreName" : {
                required: "不能为空",
            }
        },
        errorElement:"font",
        errorPlacement: function(error, element){
            error.appendTo(element.parent());
            element.next().css("color","red");
        },
        success:"valid",
        submitHandler:function(form) {
            addOrUp(flag);
        }
    });
}

　　可是死活出不来验证结果，但是通过审查元素发现表单是有变化的，但是为什么出不来验证提示，最后发现我的提交按钮用的是<a>提交</a>实现的，改成<input type="submit">就好了，这里记下来。

　　然后是关于select的验证，我的两个select一个的value是数字一个是字符串，数字的很好的用min实现了，可是字符串的不知道怎么实现，最后我通过查找资料，添加验证规则实现了select字符串的验证

bubuko.com,布布扣 
jQuery.validator.addMethod("subjectxxx", function(value, element) {
    if (value == ‘KM‘) {
        return false;
    } else {
        return true;
    }
},"请选择科目");
View Code

　　终于舒了一口气，这两天的任务可累死，但是也学到了很多东西，除了技术上的各种难题，我也深深感觉到业务逻辑对于程序员的重要性，代码写的再好，对于业务的把握不够准确，写出来的代码也是废品。
