How can we convert following javascript button to Visualforce page.Especially “GETRECORDIDS”,how can we write “GETRECORDIDS” logic in visualforce page.
I would like to convert following javascript button to visualforce page.
Please check the image i.e standard visualforce page. if the user checks the checkbox, I need that perticular “recordId” in controller.
Here
{!REQUIRESCRIPT("/soap/ajax/20.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/20.0/apex.js")}
{!REQUIRESCRIPT ("/soap/ajax/13.0/connection.js")}
var selected = {!GETRECORDIDS($ObjectType.Opportunity)};
if (selected[0] == null) {
alert("Please select at one custom object Record.");
} else{
window.location.href='/apex/TestUpdateInquiry?
id='+'{!customobject__c.Id}'+'&selected='+selected;
}
You're probably going to need a wrapper class to store your custom objects data. A wrapper class is a simple apex class, which stores a record, and adds additional information and methods.
Heres a basic example:
public class Controller {
public List<WrapperClass> wrappers;
public Controller() {
// Fill via query
wrappers = new List<WrapperClass>();
}
public List<Id> GetSelectedWrappers() {
List<Id> ids = new List<Id>();
for (WrapperClass wrapper:wrappers) {
if (wrapper.selected) {
ids.add(wrapper.record.Id);
}
}
return ids;
}
public class WrapperClass {
public sObject record { get; set; }
public Boolean selected { get; set; }
public WrapperClass(sObject record) {
this.record = record;
selected = false;
}
}
}
Inside your visualforce page, you'll need to expose a column for the user to interact with to select the wrappers.
<apex:repeat var="wrapper" value="{!wrappers}">
<apex:column>
<apex:inputCheckbox value="{!wrapper.Selected}" />
</apex:column>
<apex:column>
<apex:outputField value="{!wrapper.Name}" />
</apex:column>
</apex:repeat>
Now you've got a class which contains your sObjects data, while providing an extra field (Selected) for use on the page. You can call GetSelectedWrappers
to get the selected wrappers on the page, and then perform contextual actions based on your business needs.
For another example, you can read this developer article, which has another good example of a wrapper class, and some extra info.
