Text Boxes Validations in Jsp - javascript

In my Jsp I have two text boxes txt1 and txt2
How can I validate these two text boxes ( txtboxes won't be same...)?
(I need an alert "Both the places are same")
Here is the code:
<asp:TextBox runat="server" ID="txt1"></asp:TextBox>
<asp:TextBox runat="server" ID="txt2"></asp:TextBox>

I would suggest you add a cssClass to them. So you have easier time selecting them. Here is an example:
Mark up
<asp:TextBox CssClass="compare" runat="server" ID="txt1">test</asp:TextBox>
<asp:TextBox CssClass="compare" runat="server" ID="txt2">test</asp:TextBox>
Javascript
var elements = $('.compare');
if (elements.eq(0).html() === elements.eq(1).html()){
//do stuff
}
Fiddle Demo
Remember this only does client side validation.

asp.net Control visibility

I have a aspx form in which there are 5 controls below is the design code:
Question
<asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList><br />
Answer
<asp:DropDownList ID="DropDownList2" runat="server"></asp:DropDownList>
<asp:CheckBox ID="CheckBox1" runat="server" Text="If Other" AutoPostBack="True"
OnCheckedChanged="CheckBox1_CheckedChanged" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" />
A user selects a question from the drop down list and chooses the answer from the answer list.
If he/she doesn't find the answer in drop down list than he/she selects the checkbox and type the answer in textbox and press the submit button afterwards.
Is it possible to show the textbox and at the same time hide the drop down list using a single line code in checkbox OnCheckedChanged event?
Yes (though I'd use some more lines for better readability), you should set the visibility of the TextBox to false, to hide it at first:
<asp:TextBox ID="TextBox1" runat="server" Visible="false"></asp:TextBox>
In CheckBox1_CheckedChanged, you add the following lines:
DropDownList2.Visible = !CheckBox1.Checked;
TextBox1.Visible = CheckBox1.Checked;

set focus on different textboxes as different div is visible on a web page

I've a page where on page load event I've set focus on a textbox using javascript. But after button press I've to set focus on different text box of different asp:Panel. Is this possible using javascript? Currently I am doing this via code behind page.
<script type="text/javascript">
$(function () {
document.getElementById('<%=txtPassengerId.ClientID%>').focus();
});
</script>
<asp:Panel ID = "firstPanel" >
<asp:TextBox ID="txtPassengerId" runat="server"/>
<asp:Button ID="btn_search" runat="server" Text="Search" OnClick="btn_search_Click" />
</asp:Panel>
<asp:Panel ID = "secondPanel" >
<asp:TextBox ID="txtDestination" runat="server"/>
</asp:Panel>
After the button pressed secondPanel is visible and I need to focus on txtDestination text box. Is this possible using javascript?
Yes, you have to use the selector you've used "document.getElementById" and use the .focus() function.
document.getElementById("secondpanel").style.visibility = "visible";
document.getElementById("txtDestination").focus();
should do it. if you need more just comment.

can a required field validator can have two validation groups?

I am working on a web page.
In that web page there are 4 text boxes and each one has required field validator.
The web page has 3 buttons.
on clicking on 1st button 1st & 2nd required field validations should fire.
and on 2nd button 2nd and 3rd required field validator should fire
just like this on 3rd button 3rd and 4th should fire.
The problem is , since the one required field validator is invoked with two buttons i cant have a validation group name .
can anybody please suggest a solution .
it will be really helpful.
You can use JS, where you validate specific groups. For each button create separate validation method.
<script type="text/javascript">
function validateGroup12() {
var g1 = Page_ClientValidate("vgroup1");
var g2 = Page_ClientValidate("vgroup2");
if (!g1 || !g2) return false;
return true;
}
</script>
.aspx edit RequiredFieldValidator and set groups name into ValidationGroup
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox1" ValidationGroup="vgroup1,vgroup2" Display="Dynamic">
Have two validators, instead of one validator, for Textbox 2 and Textbox 3 with the validation groups properly set to the corresponding button validation group.
Even though this is going to duplicate the validator, this simplifies your logic.
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox1" ValidationGroup="vgroup1" Display="Dynamic">
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="TextBox2" ValidationGroup="vgroup1" Display="Dynamic">
<asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server"
ControlToValidate="TextBox2" ValidationGroup="vgroup2" Display="Dynamic">
<asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="vgroup1" />
<asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="vgroup2" />

Pass asp.net controls as params to javascript function

I am trying to get a javascript function to work properly with my asp.net controls. I have two radio buttons and three textboxes.
When the first radio button is clicked I would like to disable the third textbox and when the second radio button is clicked I would like to disable the third text box. See the attachment for a screenshot.
I have tested that the function works by adding "OnClick" to the first radio button and setting AN ALERT WHICH IS WORKING.
However, I am not sure how to pass the controls in to the function to have access to them. Anyone know how to do this?
Screenshot
ASP.NET
<asp:RadioButton ID="RadioButton1" runat="server" Checked="True" GroupName="DateTimeQuery" OnClick="TimeRangeClickEvent()"/>
<asp:TextBox ID="startdatetext" Enabled="true" runat="server" MaxLength="10"></asp:TextBox>
<asp:TextBox ID="enddatetext" Enabled="true" runat="server" MaxLength="10"></asp:TextBox>
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="DateTimeQuery" OnClick="TimeRangeClickEvent() />
<asp:TextBox ID="withinthepast" Enabled="true" runat="server" Text="1"></asp:TextBox>
Javascript
<script>
function TimeRangeClickEvent(How do I pass asp.net controls here)
{
alert('Working');
}
</script>
You should use ClientID control properties to get IDs of HTML elements and then work with them from Javascript. More info.
In Javascript:
var radio1 = document.getElementById('<%=RadioButton1.ClientID%>');
When you have all your HTML elements you just need to handle necessary change/clicked/selected events in javascript to make it work.

How do I can get asp:Panel to work properly with asp:RadioButtonList without AutoPostBack?

I'm developping a form page in a WebForms application.
I have a RadioButtonList and a Panel, and I wanted the panel to open when a especific value of the RadioButtonList was selected, how do I do this?
I've tried with AutoPostBack but I didn't like how it worked (running the page again), are there any other solutions?
Some of the places I searched for an answer recommended using the AutoPostBack property, but I personally didn't like it and so I had to find another way for it to work and so I decided to use JavaScript/JQuery...
This is an HTML sample code of an example of a RadioButtonList and a panel that opens when a chosen option on it is clicked (the value "Required" causes it to open and "Not Required" to close in this case):
<div>
<p class="space">3.2. ACCOMMODATION (*)</p>
<asp:RadioButtonList ID="accomodation" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" Width="500px">
<asp:ListItem Text="Not Required" Value="Not Required"></asp:ListItem>
<asp:ListItem Text="Required" Value="Required"></asp:ListItem>
</asp:RadioButtonList>
<asp:Panel ID="PanelAccommodation" runat="server">
<p>
Number of nights (*):
<asp:RequiredFieldValidator ID="RequiredFieldValidator12" runat="server" ControlToValidate="numberOfNights" ForeColor="red" ErrorMessage="<- Required"></asp:RequiredFieldValidator>
</p>
<asp:TextBox ID="numberOfNights" runat="server" Width="50px"></asp:TextBox>
<ajaxToolkit:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" TargetControlID="numberOfNights"
FilterType="Numbers" runat="server">
</ajaxToolkit:FilteredTextBoxExtender>
<p>Preferred Hotel:</p>
<asp:TextBox ID="preferredHotel" runat="server" Width="450px"></asp:TextBox>
<p>Preferred Hotel URL:</p>
<asp:TextBox ID="preferredHotelURL" runat="server" Width="450px"></asp:TextBox>
</asp:Panel>
</div>
The Script I used:
$(document).ready(function () {
$("#MainContent_PanelAccommodation").hide("fast");
$('#<%= accomodation.ClientID%>').find('input:radio').click(function () {
var selVal = $('#<%= accomodation.ClientID %>').find('input:checked').val();
if (selVal == "Required") {
$("#MainContent_PanelAccommodation").show("fast");
}
if (selVal == "Not Required") {
$("#MainContent_PanelAccommodation").hide("fast");
}
})
});
In this Script I use the first
$("#MainContent_PanelAccommodation").hide("fast");
to make sure that when the page runs the panel is hidden and will only open when/if "Required" is selected...
Another thing you may struggle with is what ID to put in the function since as you can see the panel ID is "PanelAccommodation", but the ID I use in the function is "MainContent_PanelAccommodation" since that's how it's recognized on your browser (to check this just select the panel's position and inspect element) you'll notice that the ID becomes "MainContent_PanelAccommodation" because it inherits from your asp:Content ContentHolderID...
Hope this helps ;) any questions just ask...
