simha how to pass a value to apex class from java script
Hi
In a java script i have done some callculations and i want to pass dat value to the apex class .
for this i just used the apex function tag but how can i pass the parameter for a function?
this is my Visualforce code
<script>
....
...
..
Age = CDateArr[3] - BDateArr[3];
document.getElementById('ageop').value = Age;
agesend();
....
....
....
</script>
<apex:actionFunction name="agesend" action="{!age}"/>
apex code is
string ageval;
...
....
public void age(ages)
{
this.ageval=ages;
}
if any one know the solution please help me
You can do it in two ways - Put the Age value from javascript into an inputHidden apex tag that has a value from your controller, or add an apex param tag onto your actionFunction:
Using an inputHidden:
<script> Age = CDateArr[3] - BDateArr[3]; document.getElementById('{!$Component.ageop}').value = Age; </script> <apex:inputHidden id="ageop" value="{!ageVal}"> Apex: public String ageVal {get; set;}
Using an actionFunction:
<script> Age = CDateArr[3] - BDateArr[3]; agesend(Age); </script> <apex:actionFunction name="agesend" action="{!doAction}"> <apex:param name="age" value="0" assignTo="{!ageVal}" /> </apex:actionFunction> Apex: public String ageVal {get; set;} public void doAction() { // Do something here if required }
Using an actionFunction would be more beneficial if you wanted to run an action (It looks as if you don't need to)
