If statement fails in Onclick javascript button

Question

I have below code where if statement that needs to work based on 'check' boolean value, is not working properly.

Although, 'check' value is true it navigates to the else block. Can someone please let me know why this is happening?

Code

    {!REQUIRESCRIPT("/soap/ajax/10.0/connection.js")}
    {!REQUIRESCRIPT("/soap/ajax/10.0/apex.js")}
    var user = sforce.connection.getUserInfo();
    var check=false;
    check=sforce.apex.execute("CheckAOCAccess","AOCAccess",{LoggedUser:"{!User.Id}"});
    alert('check@'+check);
    var vUrl = '/apex/ABV_AoCSignatureCapturOnline?actId={!Account.Id}';
    if(check==true){ // This line fails to work based on check value
        alert('check@1'+check); window.open(vUrl);
    } 
    else {//Everytime else block is fired
         alert('check@2'+check);
         alert('You are have not the privilege for Acknowledgement of Contents!');
    }

Answer 1

Can you please try below code, if the check value is coming as true from check=sforce.apex.execute("CheckAOCAccess","AOCAccess",{LoggedUser:"{!User.Id}"});

if(check=='true'){ // This line fails to work based on check value
    alert('check@1'+check); window.open(vUrl);
} 
else {//Everytime else block is fired
     alert('You are have not the privilege for Acknowledgement of Contents!');
}
