Added in v2.38 iframe Boolean flag indicating whether the form should always target the server response to an iframe.This is useful in conjuction with file uploads.

There is no specialcoding required to handle file uploads. File input elements are automaticallydetected and processed for you.Browsers that support thewill be able to upload files seamlessly and even get progress updates as the upload proceeds.For older browsers, a fallback technology is used which involves iframes since it isnot possible to upload files using the level 1 implmenentation of the XMLHttpRequest object.This is a common fallback technique, but it has inherent limitations. Working With FieldsThis page describes and demonstrates the Form Plugin's fieldValue andfieldSerialize methods.fieldValue fieldValueallows you to retrieve the current value of a field. For example, to retrieve the value of the passwordfield in a form with the id of 'myForm' you would write:var pwd = $('#myForm:password').fieldValue0;This method always returns an array. If no valid value can be determined thearray will be empty, otherwise it will contain one or more values.fieldSerialize fieldSerialize allows you to serialize a subset of a form into aquery string. This is useful when you need to process only certain fields.

For example,to serialize only the text inputs of a form you would write:var queryString = $('#myForm:text').fieldSerialize. Test Form1.By default, fieldValue and fieldSerialize only function on'successful controls'. This means that if you run the following code on a checkbox that is not checked, the result willbe an empty array.// value will be an empty array if checkbox is not checked:var value = $('#myUncheckedCheckbox').fieldValue;// value.length 0However, if you really want to know the 'value' of the checkbox element, even if it's unchecked, you canwrite this:// value will hold the checkbox value even if it's not checked:var value = $('#myUncheckedCheckbox').fieldValue(false);// value.length 1.
