我如何在同步中執行代碼？

Question

var flag = displayMessage(message);    
if(flag=='true'){ 
    SaveAndGo(paramId,uniqueControlId);        
} 

想檢查displayMessage()函數調用完成後的條件，目前它檢查條件是否並行。我嘗試了多種選擇，但它不適合我。

you could try to do something like this. based on your requirement you have to modify your code. look this : 

var val = 10; 
function displayMessage(callback){ 
    alert("first function execute"); 
    return callback(); 
} 

var flag = 10; 
displayMessage(function(){ 
    if(flag == val){ 
     alert("Now condition code execute"); 
    } 
})
