Jquery quering the db

Hey everyone, I'm currently updating a project that is to be honest a bit dated, Data access layer is in c# and screen tier is in vb(dont't ask me why). Anyway for validation you always need to postback to validate data an that, I have started using jquery (which is cool by the way) for validation and I have it working for general data i.e invalid lenght, characters etc...., I'm just wondering how to get jquery to connect to the db to see if say the name in the textbox already exists??
Cheers

I don't get it why you need to do this in jQuery, if you already have C# in the back-end...

You would, either way, need to do a post to implement such request, and implementing it in C# is the easiest thing to do. Invoking C# action from jQuery is very easy, there are plenty of examples about it in the internet.

Was kinda thinking when the page firsts loads that I could some way store the values that were in the db and then if the user entered one of those values that jquery would present the user with a message to say this name already exists. I already have validation working for valid emails, lenght etc..

Preloading the complete list of valid values probably isn't the correct approach; for one thing, it could be quite large, and for another, do you really want users to be able to see all the values in this table?

Doing an AJAX lookup at an appropriate time (send something like checkValue?typed=whattheusertyped to a simple server-side script), i.e. when they tab out of that field or pause typing for half a second, or something like that, seems like a better solution to me.

How to get td background value?

Validation against pre-fetched values is a heavier operation than server-side validation. You should just go for the latter as a much better standard Wink | ;)

It will be one short post instead of sending a whole list of records into the browser.

Hi,
I am trying to remove get some url's from a site using opera userjs feature. The problem is that the site uses the following syntax to set td background:

<td background="http://www.test.com/test.jpg" style="border:2px solid #CCCCCC; background-position:center; background-repeat:no-repeat;">

Edit: i dont't know why cp replaces some things:
1) td removed -> td background
2) background-removed -> background-position

I can access the style attributes just fine, but i cannot get the value of the background image.

I try to use it like this (prints undefined):

JavaScript

alert(img.parentNode.parentNode.background);

This works (but does not give me what i need):

JavaScript

alert(img.parentNode.parentNode.style.background);

How does the last one even work, i cant find the .background attribute from w3schools, i see that background-image attribute is available.

But mainly, how to get the td background=... value?

Thanks

try background-image. or use jQuery and do $("#id").attr("backround-image")

Hi. I want to send XML data from a windows Gadget to a aspx.net server. What is the best way to do it?
This is what i have so far, thank you Smile | :)

PS: I can't use submit forms. My gadget disapears and a small white square shows up instead.

XML

var xmlString = "<info>" +
                "  <FirstName>" + escape(first) + "</FirstName>" +
                "  <LastName>" + escape(last) + "</LastName>" +
                "  <PhoneNumber>" + escape(phone) + "</PhoneNumber>" +
                "</info>";

You could use a jQuery Ajax POST and pass the XML in as the 'data'

You seemed to have missed the concept of this site. Poke tongue | ;-P

The usual modus operandi on CP is that somebody who has an issue with something programming related, posts a message describing the problem in detail and what they already tried and so on. The CP members then try to assist the poster to resolve the issue.

Declaring you know something about javascript and google maps and bing is neither helpful nor interesting.
If you think you know enough about that topic write an article and publish[^] it here on CP.

Regards,

Manfred

I haven't yet written any aritcles here on CP, but I did have two alternates to existing tips.
If the material isn't enough to warrant an article you can post a tip instead.

Thumbs Up | :thumbsup:

URL Parameters are called QueryStrings in the web world.

Use Request.QueryString to get the parameters defined in the URL.
