How to set value of one field as param while using remote link gsp

I am using gsp for the first time and i have a requirement to update a value when a button is clicked. For that I am using remote link.

I have the below textArea with id update_${}

<g:textArea name="test" id="update_${}" value="${test?.number}" disabled="${readonly ? true : false}" />

I need to be able to set the value of the param required to be the value inside the textArea.

<g:remoteLink action="updateTest" params="{required:\$('#update_${}').val()}" update="updateOnClick" class="btn btn-default"><span class="icon-save"></span></g:remoteLink>

This is obviously a wrong approach. Could some one help me with this.

The following example uses ajax to pass all the form fields to the controller using serialize, you can pick out which ones you want in your action as we have done below by printing the value of the text area.

We then render some text which updates a div on screen.


class TestStuffController {

    def index(){}

    def myAction() {
        println params.myTextArea
        render 'Updated'


<!DOCTYPE html>
    <meta name="layout" content="main">
    <script type="text/javascript">
        $( document ).ready( function() {
            $( '#myButton' ).on( 'click' , function (event) {
                    url: "${g.createLink( controller: 'testStuff', action: 'myAction')}",
                    type: "POST",
                    data: $( "form" ).serialize(),
                    success: function ( data ) {
                        $( '#myDiv' ).html( data );
                    error: function( j, status, eThrown ) { console.log( 'Error ' + eThrown ) }
            <div id="myDiv"></div>

            <g:form id="myForm">
                <g:textArea name="myTextArea" id="myTextArea" />
                <button type="button" name="myButton" id="myButton">Update</button>

The Definitive Guide to Grails, The changes in Listing 9-14 are in bold, where the code gets the <g: remoteLink> to update the surrounding bookmark div with the contents of the response. Now ifyou change the edit view (located at grails-app/views/bookmark/edit.gsp) to simply you can getyour inline editing fields to appear when the Edit link is clicked. If you have started using Invoke-Command, then you have ran into the issue of getting local variables into your remote commands. There is a lot of advice out there on how to do this and some approaches are more clunky than others.

Here is a g:link example passing a single name value pair. To add multiple just add a comma and the second name value pair inside the square brackets.

<g:link role="button" class="btn btn-success" action="details" params="${['folderNumber' : instance.fileFolderNumber]}" title="Details">Details</g:link>

Note that g:remoteLink is deprecated I have switched to using JQuery to do Ajax calls.
