html form clear field not working
Posted: Wed Oct 23, 2013 9:44 am
I have a reset button which when clicked it clears one of the fields in the form. Here is javascript code to clear the field:
This seems to work but that particular field is one of many that holds results from a query and when I execute the query and the result is displayed on the form. I then click the reset button and the field gets cleared but the result for the field gets put back in automatically. This tells me that my query is still running so I tried to close the connection to database but it still didn't work.
Here is my query- I have pagination applied:
Any suggestions would be greatly appreciated, thanks
Code: Select all
function onFormSubmit()
{
document.getElementById('cname').value=' ';
