Code / Description
This relatively simple alertBox function presents the user with a specified message and places the cursor back into the field that failed the validation. function alertBox (vField, vMessage, vType ) {
//this function replaces the spaces in a string with the provided character
//if we pass a null message, we are doing a multiple validation test. return so we can check other conditions. if ( vMessage == "null" ) return;
//otherwise, display the error message alert ( "Field Contains Incorrect Value:\n\n" + vMessage )
//and set focus (plus select the text if a text element) if ( vType == "text" ) {
vField.focus();
vField.select();
} else {
vField.focus();
}
return;
}
