    CheckSecurityForJasperReport(filePath, fileName, fileType);

    //call another funcation to run report                                          }

我认为CheckSecurityForJasperReport应该返回/定义进一步的操作，而不是直接从那里停止。我想到的快速解决方案是这样的 - （可以优化： - ））

    function CheckSecurityForJasperReport(filePath, fileName, fileType) {
    var priviledge = false;       
            $.ajax({
                type : "post",
                dataType: "json",
                url :"../CheckExecutePriviledge",
                data: "reportpath="+filePath+"&reportname="+fileName,
                success:function(content)
                {  
                   priviledge = content;
                }   
            });           
     return priviledge; 
}

function processJasperReport(filePath, fileName, fileType) {
     // if security is enabled 
var action_go_ahead = CheckSecurityForJasperReport(filePath, fileName, fileType);
if (action_go_ahead){
// proceed 
}else{
// STOP, nothing to do here.!    
  }
}
