I am a newbie in web development. I need to create a function that works whenever user print a web page, I would like to get the date and record that date into database. Additionally, the function must work on IE & Firefox. There is onbeforeprint() event in JavaScript, but that only works in IE.
View 2 RepliesI am trying to create a web page in which the contents of one selection list
depends upon which element in another selection list is chosen, but where
the information to populate the first selection list comves from an SQL
database on the web server.
There are a couple of these situations in my application but, for example,
the first list might be a list of counties, and the second list a list of
states/provinces. Obviously the names of counties depend upon which
state/province is chosen, but there are too many possibilities to be able to
embed them within the web page itself. So when the user selects a
state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example
it is suggested to use <script src="a URL"/> to ask the server side code to
send up data of type "text/javascript". However the examples do not seem to
address how the server side code would know which state/province the user
had selected.
If there is a web site that addresses this sort of thing, I would appreciate
any pointers.

I have tried but when I click the button it prints all the contents including the image! What I want is that when the user clicks the button it shud print only the image in that page and nothing else. I have placed the image and the button in a form tag, in a separate table below the main table in which the main contents of the site contains, but it still dont work. How I can make it work?

I am building a website for my daughter. She wants to put up a list of items (groceries). The visitors would select the items they want to buy, and then print a shopping list. If there is an available online coupon, that may also be printed. There would be no need to remember the information after the visitor prints. I will be getting a JavaScript book(s) to teach myself something about the language, but for this project, I don't know where to start?
Do I need to have the items in a database, or just program a button in front of each item?
Do I need two different (or more) scripts? One to select items, one to display the items, and one to print (or use the browser print)?
I have a table in a database that gets populated by a client application. Whenever an entry is written to the table I want to fetch the data (which contains the longitude and latitude) and display a marker on Google Maps. I am using the Google Maps Javascript V3 API. Reading the tuples from the database is currently done through a PHP script. How can I update the map each time a tuple is written to the database?
View 1 Replies View RelatedI am working on a chat program. When a user logs in, a value in the database is set to 1 (online), and when he/she logs out it is set to 0 (offline). The problem is, when the user exits the browser, naturally the value is still set to 1.
I was wondering if it is possible using AJAX or otherwise to update the database on the event of browser close? I have tried onbodyunload in the body tags pointing to a file with a JavaScript function containing the PHP code (query to update the field) but cant get it to work.

I have a been developing an Online auction website using PHP and Mysql for the last few weeks. I have implemented everything including the 'bidding', 'buy it now' options of the auction etc.
I don't know much about AJAX to be honest, but I think it is the technology I need for this... My requirement is to devise a way of updating (in real-time) the current price of a particular auction product as more and more users bid on the item. Once a user bids on the item, the bid table of the database is updated with the highest bidders price. So once this value changes in the database, would it be possible to update the price on the webpage? Obviously, it is important for this update to be as accurate as possible to maintain the integrity of the auction.
I was wondering if someone could help me out with the following.I'm developing a webshop CMS in which you can create categories. By using jquery's ajax method I'm making a POST request to a PHP script which then handles all the data supplied to it. This works good and all except for the fact that after the query is being executed my HTML doesn't get updated, at least not as well as I want it to.I understand that the common way of working here is to update HTML in the success callback of the ajax method. But the thing is that every category is being displayed as a list item with an id attribute, this id corresponds to the id the category has in the database.If$.ajax tells me that everything went down smoothly and my query has been executed then there's still no way for me to know which id this new category has been given so that I can update the HTML accordingly.
What would be a "smart" way to tackle this? The first thing that comes to my mind is simply calling another script which figures out the last inserted id on the db but that would mean doing an ajax request in the callback of another ajax request? That doesn't sound right to me..
im trying to add a star rating system to a website. id like to do something elegant graphically instead of just using a drop down... the javascript framework im using is mootools and i found a great rating system here, but have no idea how to adjust it so that it updates the database with the new rating vote from the user and it calculates the new average rating.
the way i have the database set up for this is with the following fields: id (the rating's unique id) listingid (the listing that the rating corresponds to) userid (the user that entered the rating) rating (the rating itself)
i use php to communicate with a mysql database. the file im going to write will check to see if there is already a rating entered in from the logged in user. if there is, it will update it. if not, it will insert it, then it will calculate the average of all votes for that listing (rounded up) and return the new rating to the page and set the stars to reflect that rating... ive tweaked the code a bit to represent a 5 star system instead of a 10 star system and also so it can be used multiple times on a page.
heres what ive been playing with:

View 9 Replies View RelatedI have a problem, I am by no means new to PHP/Javascript but am finding an error that I cannot ridicule how to stop.Ok Ill try and explain it in simple terms:I have two divs, div1 and div2,In div1 there are links whitch are fetched from the databaseIn div2, content from links href ? in div1 is collected through AJAX.No I have a php preg_replace function that replaces it to look like <a href='#' onclick=\"showTopic(0,$char,'$1');\">$1</a> Now when you click this, it inserts into the "tpm" table in the database,(this table holds the links for div1) But it will not update the links unless i refresh the page? I would like to knoe how to update the links in div1 without refreshing, because refreshing = going back to the start of the code i am working on.
View 3 Replies View RelatedI have a form which calculates values and gives the user a total depending on their selection in the drop down box. At the moment the value is displayed in a text field and I have got all the javascript to do this.
What I would ideally want is to embed the total in the page, rather than a text field. The total appears to the user like it is normal text in a page, only it will update when the form values are changed.
I presume that I want document.write to do this? Does anyone know how I could do this/ or if there is a page that does this sort of thing where i can 'borrow' the code?
This jquery code pulls in an XML file, then passes the contents down to the nested POST call to add all of the records from the XML into a database table (which is handled by the saveSenatorRecord.asp file). This all works fine.. except that when the POST is called for "EACH" of the member nodes I expected the success: function to be called once after each of the records are added to the table. But what appears to be happening is that when function is called in the EACH property... it adds all of the records to the database table at one time, THEN it calls the success function once for each individual record.. but AFTER they have all been added.

View 2 Replies View RelatedWhat i am trying to do is allow a user to get a quote on how much an item would be if they wanted to sell it. all the data is being generated dynamically on the item and passed to this JavaScript correctly. The issue is when a user changes his mind and switches his options a few times the price goes out of wack and some times will actually be more then the original price. For example. If the item was in mint condition it would be 100 dollars. If it is " good condition" then it would loose lets say 20 percent, so it would be worth 80 dollars. Now each item has 3 sections of questions, what is the condition of the item, any "modifiers" like water damage or functional issues, and then third section is if its missing any parts or cables. All of this is being asked on 1 page, and when a user changes any of the options it should update the price on that page with out the user needing to press update. So condition goes, 100%, 70%, 40%, 20%. Modifiers are 50 percent of current price of item, so if it was "perfect (yes I know an item cant be perfect and have water damage but this is just an example) thus being 100 dollars, and has water damage, that would make it now worth 50 dollars, and has functional issues, now worth 25 dollars. If it was missing cables, it would loose lets say 5 dollars so now its worth 20 dollars. Thats an example on how i calculate the value of the items. So once again, the actual amount is being passed correctly to this script, but when you make to many changes its not happy.

I have the following code that will count the elapsed time and print the value in seconds after the user hits the stop button. However we are trying to get it to post the elapsed time in hours. So lets say the elapsed time is 20 mintues, the output would be .3 hours.
View 12 Replies View RelatedI wish to automate the population of a page by prefilling form values such as select boxes as well as fire off the change event after the value has been set. However there are at least 3/4 select boxes on one page which need populating automatically.
This works fine for the first element but not for subsequent elements all in one go when use the Trigger method of Jquery.
e.g.
$('#category').val(5);
$('#category').trigger('change'); <-- stops here.
$('#unit').val(8);
$('#unit').trigger('change');
The change event on category seems to break the flow and does not pass control back to carry on the order of processing.
i am looking to create a simple travel website where the user inputs details into a form or selects options from a drop down menu. When they submit their details they are taken to another webpage were simple adverts on the side of the webpage will relate to the options they selected from the drop down menus. For example: I select New York, and some dates. The advert on the next page will say 'Going to New York, stay at this hotel'
It will say the same if another city is selected but with the city name changed and the hotel name changed. On the second page i will ask the user to fill in personal details in a form, and again after they click submit, they are taken to another webpage and the advert will change, maybe including their name and some other details.
Is this possible and how would i go about it? The adverts only need to include some simple text for now. If the text can srcoll or move that would be a bonus. I have looked through many books and searched the web and cant find anything. I just want to use the input and selections made from the user to adapt the next webpage.
I've got this form that needs to check if the user input is already in the database, if this isn't the case it should disable the submit button and display an error depending on which input isn't found.
eg. client name isn't found...
This is the form:
