(Quick Reference) # remoteField ## Purpose Creates a text field that sends its value to a remote link when it changes. By default the parameter name sent is called 'value', this can be changed by specifying a 'paramName' attribute. ## Examples Example controller for an application called "shop":

    class BookController {    def changeTitle() {
           def b = Book.get(params.id)
           b.title = params.value
           b.save()
        }
    }
Example usages for this controller:

    <g:remoteField action="changeTitle" update="titleDiv"
                   name="title" value="${book?.title}" /><div id="titleDiv">I'm updated with the new title!</div>
## Description This tag creates an input field that fires an AJAX request when its value changes (typically when the user presses return inside the field). The exact Javascript used to fire off the AJAX request depends on which Javascript library is used. This tag also requires the use of either the <g:javascript/> or <g:setProvider/> tags. See the AJAX section of the user guide to find out more.
