You can add \n for HTML NewLine character in Apex String, and you can replace each \n by <br/> in apex:pageMessage using JSENCODE function.
Apex Controller:
public class SFController{
public String msg {get;set;}
public SFController(){
msg = 'Error Message 1' + '\n' + 'Error Message 2' + '\n' + 'Error Message 3';
}
}
Visualforce Page:
<apex:page controller="SFController">
<apex:pageMessage summary="{!SUBSTITUTE(JSENCODE(msg), '\\n', '<br/>')}" severity="Error" strength="3" escape="false" />
</apex:page>
Output:
You can add \n for HTML NewLine character in Apex String, and you can replace each \n by <br/> in Visualforce page using JSENCODE function.
SUBSTITUTE(JSENCODE(Variable), '\\n', '<br/>')
Apex Controller:
public class SFController{
public String myVariable {get;set;}
public SFController(){
myVariable = 'Sales Cloud' + '\n' + 'Service Cloud' + '\n' + 'Community Cloud';
}
}
Visualforce Page:
<apex:page controller="SFController">
<apex:outputLabel value="{!SUBSTITUTE(JSENCODE(myVariable), '\\n', '<br/>')}" escape="false"/ >
</apex:page>
Output:
This will print out the date in this format May 30 2015.
<apex:outputtext value="{0, date, MMMM d yyyy}">
<apex:param value="{!TODAY()}"></apex:param>
</apex:outputtext>
