How to use $.getJSON() method of jQuery with grails?<\/p>\n

Retriving a JSON string from Grails is very easy. You have to just write the following in your controller’s action<\/p>\n

Let me explain you with an example of populating a HTML table using JSON response:
\nIn this example, we have table with columns – name,address and gender. We want the table to be populated without doing a full page refresh, using an Ajax call.<\/p>\n

Domain Class:<\/p>\n

class MyDomain {\r\n    String name\r\n    String address\r\n    String gender\r\n}<\/pre>\n
Controller Class :<\/p>\n
\r\nclass MyController {\r\n   def someaction = {\r\n      List myDomains = MyDomain.findAllByGender(params.gender)\r\n      \/*Let say 5 objects are retrieved*\/<\/em>\r\n      render myDomains as JSON\r\n   }\r\n}<\/pre>\n
The above code in action will render a JSON<\/strong> string in the following format:<\/p>\n
[
\n{
\n\"name\"\t\t: \"John\",
\n\"address\"\t: \"New York\",
\n\"gender\"\t: \"Male\"
\n},
\n{
\n\"name\"\t\t: \"Rob\",
\n\"address\"\t: \"Indonasia\",
\n\"gender\"\t: \"Male\"
\n},
\n{
\n\"name\"\t\t: \"Shayam\",
\n\"address\"\t: \"New Delhi\",
\n\"gender\"\t: \"Male\"
\n},
\n{
\n\"name\"\t\t: \"Chang\",
\n\"address\"\t: \"Thailand\",
\n\"gender\"\t: \"Male\"
\n},
\n{
\n\"name\"\t\t: \"Ali\",
\n\"address\"\t: \"London\",
\n\"gender\"\t: \"Male\"
\n}
\n]<\/code><\/p>\n
following script would be writtent on the client Side (in the GSP):<\/p>\n
