Load data into textbox on selection of dropdown list

Question

I have a student management system project, where i am taking student enrollment form online using custom php apps.

When i am inserting enrollment form at the very first beginning of the form there is a drop down list of student iD. my client wants if he / she selects the ID of a particular student from the drop down list, his data will appear in to the text box automatically based on selection.

I know that here i require javascript but i am not sure how to do that.i have searched but didn't found any thing relevant exactly. Can any help me out.

Thanks

You need to first capture the onchange event of the drop down list. When this event fires, you will need to run javascript that makes an AJAX call to the server in order to retrieve the student's data based on the selected student in the drop down list. You will need PHP/MySQL server side code to handle this request. When the AJAX call returns with the data, you will need more javascript to populate the textbox where you want the data displayed.

I won't write the code for you, but hopefully this is enough to point you in the right direction.

Edit: If you need more details, lookup how to create an AJAX call in jQuery. Your requirements are not uncommon, so you should be able to find examples that are very near to what you need. See a relevent tutorial: jQuery AJAX Tutorial
