I am working on a registration page.I did all the validation but facing problem during username validation.when a user enter email id in the textbox,it first check whether it is present in database or not.. if not present "register successfully" otherwise "email exists"
So I posted a question on here and I'm pretty new to jQuery... I can't figure out exactly how to do this. I'm trying to, when a field blurs, run a query to see if the username is in the database, and echo whether the username is available or not if it's in the database. I have a little snipet of my page and I just don't see how to specify how to tell the script which input field, when it gets blured, to run the query...
Let me explain the issue which I'm facing with an example.My URL is http://localhost/~gaurav/dstreetmantra/register.php.One of the anchor tags in my navigation bar is <a href="register.php">Register</a>.The code needs to be able to check whether the value in this very anchor tag's href attribute is present in the URL.If it is present, the word 'Register' register would be highlighted. If not, some other link would be highlighted.As I said, I'm doing this for the navigation bar. This way, it'll check which of the links' 'href' value is present in the URL, and thus highlight that link.I'm assuming this can be done using Regex, but I do not know how to use it.
This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.
I have a textbox for entering URL. I validate that URL using regular expression. Now the problem is, How do i know whether the entered URL is exist or not.?For example, if user enter "http://www.daniweb.cam" rather entering "http://www.daniweb.com", how do i intimate them that the entered url is not valid.?
I'm not entirely sure this is possible. I hope it is, and it doesn't seem to far-fetched or impossible.
With JS, how would one go about checking if a user has DivX Web Player installed?
Usually people put in code within the embed, so if it the player doesn't load, it would have the message behind stating the fact. However I haven't seen this used at all with DivX, instead, you see pop-up boxes, whether installed or not, stating "Don't have DivX Web Player? Get it here for windows or mac"
I find this extremely annoying, and would never want such informalities on my website.
I'm making a table that is dynamically populated from XML data. One of the columns refers to an XML tag that is NOT required (hence the tag does not exist in every XML entry). How do I write a statement (if, else, or any other?) that says - check for the tag, if the tag exists, write the tag's data, if the tag does NOT exist, write "n/a".Here's the code:
I have created a popup at the following page: http://suawg.osugv.servertrust.com
If i click on 18+ then it gets redirected to http://suawg.osugv.servertrust.com/default.asp
if i click on i am not 18 then it gets redirected to google.com
if i have chosen 18+ then the cookie should be created and if by mistake i again go to http://suawg.osugv.servertrust.com that is popup page it should get redirected to http://suawg.osugv.servertrust.com/default.asp
I would like to check the querystring to see if a variable exists.If groupid exists in the querystring and has ANY value then show a hidden div (#closedMsg). I do not care what the value of the groupid is I just want to verify that it has a value.If the url looks like this "www.somesite.com?groupid=" with no value for groupid, I do not want to show the hidden div.
Code: var strUsersName = new Array("John","Mac","George");
I want to check, if the particular loggedin user for example Mac is available in the array list declared.How to check in a efficient way, if the particular user loggedin is available within the array declared.I tried this, but I am not sure, if it is correct:
Code: var strUsersName = new Array("John","Mac","George"); var L=strUsersName.length;
