Question

We have a legacy web app at work that lets customer view their data on a graph. They select options on a <form> and then submit. A new page is displayed with instructions and FAQ’s while a java applet displays the graph. If I hit the F5 key in my browser, it resubmits the form and closes/re-opens the java applet which displays a graph with updated data.

Is there a way to duplicate that ‘function’ of resubmitting the graph in an automated fashion on a timer? So the graph applet would redisplay every xx minutes without user intervention?

A simple meta refresh doesn’t work as it doesn’t resubmit the form. I’m somewhat limited as to what I can modify. The web app is completely generated by PL/SQL.

EDIT

For clarification: the <form> that the user filled in that produced the new page and java applet is not on the current page. So there is no form to resubmit. Hitting the F5 key will auto-resubmit the form that produced the current page. I am looking for a programmatic way to do the same, if possible.

Answer 1

Name your form <form name="myform"> and I suppose you could

setInterval(myMethod, 300000);

function myMethod(){
    document.forms["myform"].submit();
}
