Apex Page Message: count of checkboxes selected

I have a pageBlockTable with inputcheckbox. I want to count the number of records selected and display the count in the ApexPages.message.

 

Any idea how I can do this? Thanks!!

<apex:pageBlockTable value="{!priceist}" var="p" id="results">

<apex:column >
<apex:inputCheckbox value="{!p.selected}" onchange="updateSelectCount(this);"/>
</apex:column>


<apex:column >
...
</apex:column>

</apex:pageBlockTable>
   
   
</apex:pageBlock>

 

//Apex class


 public PageReference approveRecord(){

 

    // my logic and finally


  ApexPages.addMessage(new ApexPages.message(ApexPages.severity.Confirm,'All records successfully approved!'));    // Here instead of 'All' i want {!count}

}

The logical way would be to iterate through the list and check if p.selected = true and add to a counter. I would be interested in a quicker way to achieve this. What problem are you facing anyways?

Hi,

 

The Other way is to use the jQuery to count the number of checkboxes.

 

$("input:checkbox:checked").length;

Hello rov, I see you are calling JavaScript function "updateSelectCount" on the onchange event. I would try the following: 1) Declare a global JavaScript variable that controls the number of checked options; 2) Update that variable anytime anyone clicks or unclicks an option; 3) Pass the value of the global variable as a parameter into function "approveRecord".

Can someone please check what i am doing worng when concatenating the countofapprovedrecords to the Apexpage message?

 

As suggested by @vbs, I am iterating through the list, checking if record.selected = true and adding to the counter.

My debug statement, shows me the number of selected records.

I am converting the integer to a string (debugs show correct converted value) and using this string in my Apex.messages, howver, the message doesn't display the string that i converted from ineteger value.

 

 

public integer countapprovedrecords=0;

for (myWrapper record : IncList){

 if(record.selected){

  countapprovedrecords++;
        }
}

if (!Apexpages.hasMessages()){
        string countstring = string.valueof(countapprovedrecords);
        system.debug('integer converted to string' +countstring);
        ApexPages.addMessage(new ApexPages.message(ApexPages.severity.Confirm,'countstring'+  'records successfully approved!'));
                           
}

Hi,

 

Try this one. countrstring  shouldn't within single quotes.

 

ApexPages.addMessage(new ApexPages.message(ApexPages.severity.Confirm, countstring+  'records successfully approved!'));
