How would I go about outputting something when a database value is being changed?
e.g. If im typing in a text field, which is saving what ive typed every time i keyup into a database field, it then shows on another page on another user computer as "User is typing something in field X"?
If no typing is happened, i.e. the database field value is not changing, nothing is echoed out.
It would also be cool to have something show "User is deleting text from field X" when the field value is getting shorter.
In pseudo code, something like if the value of database string is bigger than 100ms ago, echo out "user is typing something in", and conversly, if string is getting shorter echo out "user is deleting stuff".
Basically i have a form with jqueryui implemented (autocompletes) and I need the form to display the number of current results as the user fills the form, i.e. once the user has finishedinputtingdata into one field, the form will query the database with the current form details and return just the number of results ($mysql_num_rows)
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.
I am currently trying to create a live search box that as I type it will start displaying results that match.but it retrieves its data from an XML file, I need mine to retrieve from a column called FirstName within a table of an Access database.
For a social system I am working on, I am in desperate need of being pointed in the right direction for how to create a live ajax feed which calls data from a database.
could someone please point me in the right direction for creating an AJAX page that displays "live" data from a mysql database? I need the page to update its self every time data changes in a mysql table.
Not sure if this is the correct forum as it covers data retrieved from mysql in a .js file...
I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.
The following function takes three different fields (which combined make up a phone number) and tests it to make sure that all the characters entered are integers. If this is true, it sets form.Phone.value = entirephonenumber. I would like to incorporate an additional test which, after determining that all characters in the string are integers, checks to make sure that the string length is 10. If it is less than 10 or more, I want the entire function to return false and display an error message (the same one is fine..) Code:
i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?
i want a value search(find) to database(table), this requires an ajax call to a server page? if want show result search live(online) and search letters to letters (transliteration), how is it?
I have been searching how to connect to a database and execute some queries, and then use the data that I get to populate some tables in a web page, all this using javascript.
I am confused because I have seen in some webpages that javascript is not designed to connect with databases, and also I have see other pages where they say that it is possible.
Does anyone know if it is possible to use javascript to connect to a database (informix), and execute some procedures or queries?
I am having no luck with my post form to mysql. It is only posting the first letter of the word/phrase for the text input fields to the mysql database. It is a photo and text post form. The photo and only first letter of text are posting to database. I am using Jqtouch, jquery, and phonegap.
I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.
This,among other things, causes a function called load to be called on the href of the anchor. This works fine. Howver I want to use the live() function with this as I am going to dynamically change the links in the listnav div. I tried doing it like this :
But that does not work. My question is how would I go about changing this function so that the actions are applied to any new anchors added to the div dynamically?
