如果所有的标签都在form内，就可以用$('#YourFormId').serializeArray()；

如果没有form，就可以用下面的方法

　　var ID = $("input[name='ID']").val();
        var name = $("input[name='name']").val();
        var date = $("#spdate").find("input").val();
        var safe = $("input[name='safe']").val();
        var NUM = $("#spbatch").find("input").val();
        var WANRR = $("input[name='WANRR']").val();
        var WANRG = $("input[name='WANRG']").val();
        var WANRY = $("input[name='WANRY']").val();
        var PTimes = $("#spprint").find("input").val();
        var result = '{ "ID":" ' + ID + '","name":"' + name + '","date":"' + date + '","safe":"' + safe + '","NUM":"' + NUM + '","WANRR":"' + WANRR + '","WANRG":"' + WANRG + '","WANRY":"' + WANRY + '","PTimes":"' + PTimes + '"}';

//var params = [];
        //params.push({ "ID": ID, "name": name });
        //params.push({ "date": date, "safe": safe });
        //params.push({ "NUM": NUM, "WANRR": WANRR });
        //params.push({ "WANRG": WANRG, "WANRY": WANRY });
        //params.push({ "PTimes": PTimes });
        //var json = JSON.stringify(params);
        //var e = new RegExp("{", "g");
        //json = json.replace(e, "");
        //e = new RegExp("}", "g");
        //json = json.replace(e, "");
        //json = json.replace("[","{").replace("]","}");
