Tips: Iterating a map in Visualforce page
October 9, 2012 / / Comments Off on Tips: Iterating a map in Visualforce page
The common solution to display a list of values or SObject’s field value in Visualforce page is looping through a List. For example:
Controller method
List keyList = new List{'value for first','value for second','value for third'};
public List getKeyList(){
return keyList;
}
Visualforce page
However, sometimes we may need to construct our data into a map instead and have it displayed in Visualforce page. Here is how you can loop through a map and it’s value:
Controller method
public Map getDemoMap(){
Map demoMap = new Map();
demoMap.put('first', 'value for first');
demoMap.put('second', 'value for second');
demoMap.put('third', 'value for third');
demoMap.put('forth', 'value for forth');
return demoMap;
}
Visualforce page
