Grails remote jQuery form validation

<script type="text/javascript"> $(function (){     $("#form").validate({         rules: {             'address.postalCode': {                 required: true             },         },         messages: {             'address.postalCode': {                 required: "Please enter a postal code."             }         }     }); }); </script> <g:form method="post" action="register" name="form">     <input type="text" name="address.postalCode" id="postalCode" />     <input type="submit" value="Proceed" /> </g:form>

Grails Return JSON

Domain Class:

class MyDomain {

String name

String address

String gender

}

Controller Class :

class MyController {

def someaction =
{

List myDomains = MyDomain.findAllByGender(params.gender)

<em>/*Let say 5 objects are retrieved*/</em>

render myDomains as JSON

}

}

The above code in action will render a JSON string in the following format:

[
{
"name" : "John",
"address" : "New York",
"gender" : "Male"
},
{
"name" : "Rob",
"address" : "Indonasia",
"gender" : "Male"
},
{
"name" : "Shayam",
"address" : "New Delhi",
"gender" : "Male"
},
{
"name" : "Chang",
"address" : "Thailand",
"gender" : "Male"
},
{
"name" : "Ali",
"address" : "London",
"gender" : "Male"
}
]

following script would be writtent on the client Side (in the GSP):

<script> $.document.ready(function(){ $('#someid').click(function(){ <strong>$.getJSON</strong>("${createLink(controller:'my',action:'someaction')}",{gender:'Male', ajax: 'true'}, function(myDomains){ var myHTMLString = '' for(var i = 0 ; i < myDomains.length ; i++) { myHTMLString = myHTMLString + '<tr><td>' + myDomains[i].name + '</td>' myHTMLString = myHTMLString + '<tr><td>' + myDomains[i].address + '</td>' myHTMLString = myHTMLString + '<tr><td>' + myDomains[i].gender + '</td></tr>' } $('table#mytable').html(myHTMLString) }) }) }) </script>

 

The HTML code would be like this :

<div id="someid">
Click for JSON Response
</div>
<table id="mytable">
<!–empty table –>
</table>

When you click on the displayed text the html page would become like following:

<div id="someid">
Click for JSON Response
</div>
<table id="mytable">
<tr>
<td>John</td>
<td>New York</td>
<td>Male</td>
</tr>
<tr>
<td>Rob</td>
<td>Indonasia</td>
<td>Male</td>
</tr>
<tr>
<td>Shayam</td>
<td>New Delhi</td>
<td>Male</td>
</tr>
<tr>
<td>Chang</td>
<td>Thailand</td>
<td>Male</td>
</tr>
<tr>
<td>Ali</td>
<td>London</td>
<td>Male</td>
</tr>
</table>

any kind of suggestions and comments are welcome……

Groovy List<Integer>

List<Integer> list = [5,6,7,8]

list.each({line -> println line})

list.each({println it})

Basic Groovy Lang…

println '######################## List ##########################\n'

List<Integer> list = [1,2,3,4,5,6,7,7,6,5,6,7,5,6,5]

println 'value list[0] is '+list[0]

println 'value list[3] is '+list[3]

println 'value list[8] is '+list[8]

println 'size = '+list.size()

 

println '######################## MAP ##########################\n'

Map map = [:]

def map2 = ["Jim":"Knopf", "Thomas":"Edison"]

println map2["Jim"]

map2["Test"] = "Tester"

println map2["Test"]

 

println '######################## For ##########################\n'

for (i in 0..9) {

println ("Hello $i" )

}

 

println '######################## Defines a string with special signs ##########################\n'

// Defines a string with special signs
