JavaScript - How do I pull rows from mysql with Javascript onchange function
Asked By Olusegun A. on 20-Nov-12 10:27 AM
Hello there,
I have a website where info of registered member from various countries and states are collected. On my search form, I have 3 fields; Country, State and Sex. I listed all the countries of the world in my search (as a dropdown), but the state field is empty. Want i want is that once a visitor select a country, i want only the states of that country which registered members have are in my database to be pulled into the state field, instead of all the state of that country.
Eg 3 members from USA are from New York, New Jersey and Georgia. On selecting USA in the country dropdown, only these 3 state should appear under the state insteadt of the 50 states in america.
Pls help.
Thanks

You will have to set up a server side http handler to accept requests from JavaScript. JavaScript cannot access MySql (or any other server side database) directly. So, you'd have a server side page (asp.net or php I guess) that would connect to the database and return html/json to your JavaScript call over XmlHttpRequest.

MySQL database server was born out of an internal company project spearheaded by employees of the Sweden-based TcXDataKonsult firm. Their project, dubbed MySQL, was first released to the general public at the end of 1996. The software proved so popular that in 2001 they founded a company based entirely around MySQL specific service and product offerings, calling it MySQL AB. MySQL is a relational database server that inches closer to the SQL-92 standard with each t encounter too many surprises if you're familiar with another database product. What is MySQL?
