We can call controller's function from javascript with the help of
- <apex:actionFunction>
VF Page:
<apex:page controller="testClass">
<apex:form >
<apex:actionFunction name="controllerMethod" action="{!check}"/>
</apex:form>
<script>
window.onload = function deleteRecord(){
controllerMethod(); // this calls the actionFunction defined in the VF page.
}
</script>
</apex:page>
Controller:
public class testClass{
public void check(){
String s= 'Function called';
apexPages.addMessages(s);
}
}
</script>
</apex:page>
Controller:
public class testClass{
public void check(){
String s= 'Function called';
apexPages.addMessages(s);
}
}
2. JavaSript Remoting:
VF Page:
<apex:page controller="testClass">
<script>
window.onload = function deleteRecord(){
var stringName = 'test';
<apex:page controller="testClass">
<script>
window.onload = function deleteRecord(){
var stringName = 'test';
Visualforce.remoting.Manager.invokeAction('{!$RemoteAction. testClass. check}',
stringName, function(result, event){
if (event.status) {
if(result.length > 0){
if (event.status) {
if(result.length > 0){
//logical operation
}
}
},
{escape: true}
},
{escape: true}
}
</script>
</apex:page>
Controller:
Global class testClass{
@RemoteAction
Global void check(String name){
String s= name;
apexPages.addMessages(s);
}
}
</script>
</apex:page>
Controller:
Global class testClass{
@RemoteAction
Global void check(String name){
String s= name;
apexPages.addMessages(s);
}
}
