我有两个通过vb.net编程的Ajax验证程序调用扩展器。我正在验证一个文本框,但我希望弹出窗口出现在另一个文本框旁边。如何告诉Ajax弹出窗口出现在哪里?
Dim custval As New CustomValidator
custval.ID = "ValidPage"
custval.ErrorMessage = "<font color=red>Please Enter a 'To' Date"
custval.SetFocusOnError = True
custval.ForeColor = Drawing.Color.Red
custval.EnableClientScript = True
custval.ControlToValidate = cell.Controls(18).ID
custval.ClientValidationFunction = "ClientValidate"
custval.Display = ValidatorDisplay.None
Dim custvalex As New AjaxControlToolkit.ValidatorCalloutExtender
custvalex.ID = "VCEcustval"
custvalex.TargetControlID = "ValidPage"
custvalex.HighlightCssClass = "validatorCalloutHighlight"
'---------------------------------------------------------------
Dim custval2 As New CustomValidator
custval2.ID = "ValidPage2"
custval2.ErrorMessage = "<font color=red>Please Enter a 'From' Date"
custval2.SetFocusOnError = True
custval2.ForeColor = Drawing.Color.Red
custval2.EnableClientScript = True
custval2.ControlToValidate = cell.Controls(23).ID
custval2.ClientValidationFunction = "ClientValidate2"
custval2.Display = ValidatorDisplay.None
Dim custvalex2 As New AjaxControlToolkit.ValidatorCalloutExtender
custvalex2.ID = "VCEcustval2"
custvalex2.TargetControlID = "ValidPage2"
custvalex2.HighlightCssClass = "validatorCalloutHighlight"
cell.Controls.Add(custval) '27
cell.Controls.Add(custvalex2) '28
cell.Controls.Add(custval2) '29
cell.Controls.Add(custvalex) '30
function ClientValidate(sender, args) {
// Get Both form fields
var hid = $get('<%=HiddenField1.ClientID%>');
var hid2 = $get('<%=HiddenField2.ClientID %>');
var hidval = hid.value;
var hid2val = hid2.value;
var txtdate1 = $get(hidval);
var txtdate2 = $get(hid2val);
// do you client side check to make sure they have something
if (txtdate1.value != '' && txtdate2.value == '') {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
function ClientValidate2(sender, args) {
// Get Both form fields
var hid = $get('<%=HiddenField1.ClientID%>');
var hid2 = $get('<%=HiddenField2.ClientID %>');
var hidval = hid.value;
var hid2val = hid2.value;
var txtdate1 = $get(hidval);
var txtdate2 = $get(hid2val);
// do you client side check to make sure they have something
if (txtdate2.value != '' && txtdate1.value == '') {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
我知道这两个javascript函数可以分开。但是我怎样才能移动弹出窗口呢?
