方法一：

var trList = $("#history_income_list").children("tr")
    for (var i=0;i) {
        var tdArr = trList.eq(i).find("td");
        var history_income_type = tdArr.eq(0).find("input").val();//收入类别
        var history_income_money = tdArr.eq(1).find("input").val();//收入金额
        var history_income_remark = tdArr.eq(2).find("input").val();//    备注
        
        alert(history_income_type);
        alert(history_income_money);
        alert(history_income_remark);
    }

方法二：

$("#history_income_list").find("tr").each(function(){
        var tdArr = $(this).children();
        var history_income_type = tdArr.eq(0).find("input").val();//收入类别
        var history_income_money = tdArr.eq(1).find("input").val();//收入金额
        var history_income_remark = tdArr.eq(2).find("input").val();//    备注
        
        alert(history_income_type);
        alert(history_income_money);
        alert(history_income_remark);
