JQuery给指定的表格的输入框或其他组件赋值

参考代码如下：

function modifyApplyMoney()
{
    var applymoney = $("#applymoney").val();//申请金额
    var plandeposit = $("#plandeposit").val();//拟交保证金
    if (plandeposit == "")
    {
        plandeposit = 0;
    }
    if (applymoney == "")
    {
        applymoney = 0;
    }
    if (plandeposit != 0 && applymoney != 0 && (applymoney - (plandeposit*10000)) < 0)
    {
        alert("拟交保证金不能大于拟担保金额!");
        $("#plandeposit").val("");
        return;
    }
    var fee = 0;
    var assureterm = 0;
    var assuretermtype= $("#assuretermtype").val();//担保期限类型
    var table=$("#projfee");

    var index=0;

<td style="text-align:center;">

 class="easyui-validatebox feewill"

$(trs[i]).find(".feewill").val(roundFloat(refyearfee,2))；就是赋值；
