Below are some bits and pieces of Javascript I've collected over the years that have come in handy.
Submit a form on a timer(in milliseconds).
setTimeout('document.formname.submit()',1000);
A function that calls other functions to execute.
//if all functions return true then all systems go!
function RunAllFunctions() {
if(Function1() && Function2() && Function3()) {
return true;
}
else {
return false;
}
}
Send browser to a certian url. Some examples.
window.location.href = 'http://www.blah.com/warn2.shtml'; top.location.href = 'http://www.blah.com/warn2.shtml'; parent.location='http://www.blah.com/warn2.shtml';
Keep your javascript in file on the server.
<SCRIPT LANGUAGE="JavaScript" src="javascript/javascriptfile.js"></script>
Rename a fieldname. Good for PHP arrays submitted by a form when the form name has "[]" in the name.
//rename list items for php array
document.formname.fieldname.name="list1[]";
document.formname.fieldname.name="list2[]";
Keep a person from going back to a page the just came from.
window.history.forward(1);
Copy values from one frame to another.Copy from frame's name "copyFrom".Copy to frame's name "copyTo".
parent.copyTo.document.formname.fieldname.value = parent.copyFrom.document.formname.fieldname.value;
//copy drop downs value
if (parent.copyTo.document.formname.fieldname.options[parent.copyTo.document.formname.fieldname.selectedIndex].value == whatever){
parent.copyFrom.document.formname.fieldname.value = "whatever"
}
