Question

我正在为某些功能编写一些代码

我的第一个文本框

<asp:TextBox ID="txtLeasePaymentFixed" type="text" runat="server" class="number" CssClass="form-control" Style="text-align: right" TabIndex="101"  placeholder="e.g 123,456,789"  onKeyUp="fncCalculateSum()" onBlur="fncCalculateSum()"></asp:TextBox>

我的第二个文字框是

<asp:TextBox ID="txtLeasePaymentVairable" type="text" runat="server" CssClass="form-control" Style="text-align: right" TabIndex="102"  placeholder="e.g 123,456,789" onKeyUp="fncCalculateSum()" onBlur="fncCalculateSum()"></asp:TextBox>

标签Toltal显示的是这样的

   <asp:Label ID="lbltotal" runat="server" Text=""></asp:Label>

调用onblur和onkeyUp的函数是这样的：

function fncCalculateSum() {


        var LeasePaymentFixed = $('#MainContent_txtLeasePaymentFixed');
        var LeasePaymentVariable = $('#MainContent_txtLeasePaymentVairable');
        if (LeasePaymentFixed.val() == '' || LeasePaymentFixed.val() == null) {
            PaymentFixed = 0;
        }
        else {
            PaymentFixed = parseFloat(LeasePaymentFixed.val());
        }
        if (LeasePaymentVariable.val() == '' || LeasePaymentVariable.val() == null) {
            PaymentVariable = 0;
        }
        else {
            PaymentVariable = parseFloat(LeasePaymentVariable.val());
        }


        (Sum) = PaymentFixed + PaymentVariable

        if ((LeasePaymentFixed.val().trim() == '' && LeasePaymentVariable.val().trim() == '') || (LeasePaymentFixed.val() == null && LeasePaymentVariable.val() == null)) {
            $("#MainContent_lbltotal").text('');
        }
        else {

            $("#MainContent_lbltotal").html(parseFloat(Sum));
        }

    }

现在我使用jQuery代码在每3位数之后以国际格式应用逗号

        $('#MainContent_txtLeasePaymentFixed,#MainContent_txtLeasePaymentVairable,#MainContent_lbltotal').keyup(function(event){
            // skip for arrow keys
            if(event.which >= 37 && event.which <= 40){
                event.preventDefault();
            }
            var $this = $(this);
            var num = $this.val().replace(/,/gi, "").split("").reverse().join("");

            var num2 = RemoveRougeChar(num.replace(/(.{3})/g,"$1,").split("").reverse().join(""));

            console.log(num2);


            // the following line has been simplified. Revision history contains original.
            $this.val(num2);
        });


        function RemoveRougeChar(convertString){


            if(convertString.substring(0,1) == ","){

                return convertString.substring(1, convertString.length)            

            }
            return convertString;

        }

当我在第一个文本框中写数字时，它带有逗号，这很好。我在第二个文本框中写入时也是如此，但它并不显示标签上所有数字的总和。

小心！您使用逗号进行var tableColumns = new HashMap[String, Set[String]] with MultiMap[String, String] sqlContext.sql("select distinct LOOKUP_TABLE,LOOKUP_COLUMN from primaryLookUp").collect() .map { x => tableColumns.addBinding(x.getString(0), x.getString(1)) }转换会丢失数据：

var lookupDFs = new HashMap[String, DataFrame]

var df: DataFrame = null
tableColumns.foreach { keyVal =>

  sqlContext.read.jdbc("myjdbcurl",keyVal._1,properties.registerTempTable(keyVal._1)
  keyVal._2.foreach { value =>
    df = "select distinct " + value + " from " + keyVal._1
    df.show
    lookupDFs.put(keyVal._1 + "##" + value, df)
  }
}

您应该检查转换情况并确保正在处理正确的数字。

添加2个数字并在标签上用逗号显示结果
