javascript验证

Question

我在javascript验证条件中面临一些问题，我需要更新文本框中的日期，并且该日期不应从applicationdate追溯，如果我将日期从applicationdate更新为backdate，则会收到警告信息masg E-CLRDATELTTXNDATE。问题是，如果我单击链接到该日期文本框的任何文本框，即使单击此警报窗口的“确定”按钮，此警报也会继续重复。

   function txtClearingDate_blur(i) {
        i--;
        if (document.frmPaymentClearing.hidTxnCount.value == 1) {
        if (("" + document.frmPaymentClearing.txtClearingDate.value).length > 0) {
                    if (!isDate(document.frmPaymentClearing.txtClearingDate.value,document.frmPaymentClearing.hidShortDateFormat.value,document.frmPaymentClearing.hidDateSeperator.value)) {
document.frmPaymentClearing.txtClearingDate.focus();return;
                         } else {
                                i++;
                    if (isClearingDateGreaterThanAppdate(i--)) {
                                        document.frmPaymentClearing.txtClearingDate.focus();
                        GetAlertMessage("E-CLRDATE","E","","","");
                     }
                                 i++;
                    if (!isClearingDateGreaterThanTxnDate(i--)) {
                        document.frmPaymentClearing.txtClearingDate().focus();

                        GetAlertMessage("E-CLRDATELTTXNDATE","E","","","");

                    }


                    }
                }
            } else {
                if (("" + document.frmPaymentClearing.txtClearingDate[i].value).length > 0) {
                    if (!isDate(document.frmPaymentClearing.txtClearingDate[i].value,document.frmPaymentClearing.hidShortDateFormat.value,document.frmPaymentClearing.hidDateSeperator.value)) {
                                       document.frmPaymentClearing.txtClearingDate[i].focus();return;
                                } else {
                                        i++;
                    if (isClearingDateGreaterThanAppdate(i--)) {
                                                   document.frmPaymentClearing.txtClearingDate[i].focus();
                               GetAlertMessage("E-CLRDATE","E","","","");
                    }

                    i++;
                    if (!isClearingDateGreaterThanTxnDate(i--)) {
                        document.frmPaymentClearing.txtClearingDate(i).focus();
                        GetAlertMessage("E-CLRDATELTTXNDATE","E","","","");
                        return;
                    }

                    }

                }

            }
        }

这是因为您在警告错误消息之前调用了.focus()事件。 将其放在警报电话之后。

字段接收焦点，然后在警报上失去焦点，对未更改的数据再次触发模糊事件。
