ajax with grails

**ibs** · Oct 13th, 2010, 09:42 AM

Hello!

I wanted to do some Ajax with Grails. How can I change the below code in order to directly read out some information from the xml:

Code:

def listXml ={
        def books = Book.list(params)
        render(contentType:"text/xml"){
            booklist{
                for(b in books){
                    book(id:b.id){
                        title(b.title)
                        author(b.author)
                        
                    }
                }
            }
        }
    }
    
    def showBooks = {
        render(template:'results', model: [value: params.value, books: books])
    }

search.gsp
<html>
  <head>
    <meta name="layout" content="main" />
    <title>Books Find</title>
  <g:javascript library="scriptaculous" />
</head>
<body>
  <h2>Ajax Search</h2>
<g:formRemote name="showBooks"
              url="[controller:'book',action:'showBooks']"
              update="[success:'results'" >
  <input type='text' name='value' value="${value}" />
  <g:submitButton name="search" value="Search" />
</g:formRemote>
Results:
<div id="results">

  
</div>
</body>
</html>

_result.gsp
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Sample title</title>
  </head>
  <body>
    <h1>Results</h1>
    <ol>
    <g:each var="book" in="${books}">
      <li>${book?.author}
      <g:if test="${book.title}">- </g:if> ${book?.title}
      </li>
    </g:each>
  </ol>
  </body>
</html>

Hi, do you want use ajax to show the xml-render ? if that you can try this:
I use jquery.

$.get("host/controller/listXml", function(data){
var books = $(data).find("booklist>book");
alert(books.size());
var bookOne = books[0];
var bookOneTitle = bookOne.firstChild.textContent;
var bookOneAuthor = bookOne.childNodes[1].textContent;
alert(bookOneAuthor);
//you can append these vars to your page.
//like $("#result").html(bookOneTitle);
});

good luck.
