Question

伙计们，我正在修改一个当前的功能，以便使用两个变量。我在代码片段中显示了过去和现在的版本。
基本上我想要的是两个if conditions中的任何一个，即 First Condition 和 Second Condition 是的，不要执行函数的剩余逻辑。如果两者都为假，则继续执行该函数的剩余代码。
我想我正在制作一个在某处愚蠢的错误，如果第一个条件成立，执行就在那里停止。（我知道这是因为最后的回复声明。）即使第一个条件为真，我如何确保第二个if条件并返回return

function myAlgorithm(code1, code2) {

   if(eval(code1)) {

      if(First condition) {
         alert("You cant continue");

         return;
      }
    }

    if(eval(code2)) {
       if(Second condition){
         alert("You cant continue");
       return;
      }

    }

    //If both of the above if conditions say "You cant continue", then only
    //disrupt the function execution, other wise continue with the left
    //logic

    //Rest of the function logic goes here

}

以前的代码是：

function myAlgorithm() {

   if((First Condition) && (Second Condition)){
    alert("You cant continue");

    return;
   }

  //Rest of the function logic goes here
}

Answer 1

使用变量并在满足条件后递增。然后检查变量是否增加。

function myAlgorithm(code1, code2) {
    var count = 0;
    if (eval(code1)) {

        if (First condition) {
            alert("You cant continue");

            count++;
        }
    }

    if (eval(code2)) {
        if (Second condition) {
            alert("You cant continue");
            count++;
        }
    }
    if (count == 2) {
        return "both conditions met";
    }

    //If both of the above if conditions say "You cant continue", then only
    //disrupt the function execution, other wise continue with the left
    //logic
    //Rest of the function logic goes here
}

Answer 2

可以使用标志变量来跟踪您的情况，然后像之前一样检查它们

function myAlgorithm(code1, code2) {
 var flag1;
 var flag2
if(eval(code1)) {
  flag1 = First condition
}

if(eval(code2)) {
  flag2 = second condition
}

if(flag1 && flag2){
  return;
}
//If both of the above if conditions say "You cant continue", then only
//disrupt the function execution, other wise continue with the left
//logic

//Rest of the function logic goes here

}

Javascript如果条件返回
