JQuery :: Remove DIVs With The Duplicate IDs?

Dec 3, 2010

I have 2 divs with 2 nested divs in them. Let's say div1 contains div11 and div12 and div2 can also contain div11 and div12. I know that this is not normally allowed but I am using jTemplates and they do allow you to print the div11 and div12 twice or more on the same page. The HTML looks like this:

<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>

How do I ensure that I only have one div with the unique ID loaded on the page, so I don't get in any duplicate DIVs. The result should look like this:

<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
Some other text

Is there any way to check for a duplicate ID in either jQuery/javascript language and remove all but one using each or some other method?

SQL Server :: How To Remove Rows For Duplicate Field Values

Oct 18, 2010

suppose I am having sample table like below.

I need to remove duplicate orderid's and i need all column names also while doing query.

note that rows are not in the order. Order will be like this only.

I am able to get the records which are duplicated but not able to delete further.

In this case how to delete?

My consideration is that only distinct orderid's should be there in the table. Not bothering about the which orderid row is being deleted.

name orderid destination
a 1 aaa
d 2 ddd
b 1 bbb
f 3 fff
e 2 eee
g 4 ggg
h 3 hhh
c 1 ccc

Forms Data Controls :: Delete One Duplicate Record Of Many Duplicate Records

Mar 15, 2010

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.

I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:

I used the following query to load in duplicate records:

SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))

ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006

What is the query to delete single duplicate record instead of deleting all duplicate records?

Asp - Duplicate Items In Dropdownlist

Jan 5, 2011

I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).Here's my code:

<asp:DropDownList ID="DropDownMake" runat="server"
DataSourceID="SqlMakes" DataTextField="Make" DataValueField="Make"
AppendDataBoundItems="True" EnableViewState="False" AutoPostBack="True">
<asp:ListItem Selected="True" Value="All">All</asp:ListItem>
<asp:DropDownList ID="DropDownModel" runat="server"
AppendDataBoundItems="True" AutoPostBack="True" DataSourceID="SqlModels"
DataTextField="Model" DataValueField="Model" EnableViewState="False">
<asp:SqlDataSource ID="SqlMakes" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Make] FROM [Parts]">
<asp:SqlDataSource ID="SqlModels" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Model] FROM [Parts] WHERE ([Make] = @Make)">
<asp:ControlParameter ControlID="DropDownMake" Name="Make"
PropertyName="SelectedValue" />
'And in the VB file:
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
DropDownMake.SelectedValue = Request.QueryString("Make")
DropDownModel.SelectedValue = Request.QueryString("Model")
End Sub

If I remove the line "DropDownMake.SelectedValue = Request.QueryString("Make")" it doesnt produce duplicates anymore. What is going on?? I swear I've spent more time developing entire iphone app.

Prevent Duplicate Postback In (C#)

Aug 27, 2010

Simple one here... is there a clean way of preventing a user from double-clicking a button in a web form and thus causing duplicate events to fire?

If I had a comment form for example and the user types in "this is my comment" and clicks submit, the comment is shown below... however if they double-click, triple-click or just go nuts on the keyboard they can cause multiple versions to be posted.

Client-side I could quite easily disable the button onclick - but I prefer server-side solutions to things like this

Is there a postback timeout per viewstate that can be set for example?
