有没有办法在nodejs中停止执行async系列的下一个函数？

Question

  async.map(list, function(object, callback) {
    async.series([
      function(callback) {
        console.log("1");

        var booltest = false;
        // assuming some logic is performed that may or may not change booltest
        if(booltest) {
            // finish this current function, move on to next function in series
        } else {
           // stop here and just die, dont move on to the next function in the series
        }

        callback(null, 'one');
      },
      function(callback) {
        console.log("2");
        callback(null, 'two');
      }
    ],
    function(err, done){
    });
  });

有没有某种方法,如果函数1如果booltest评估为真,不要继续下一个输出"2"的函数？

Answer 1

如果你使用true作为错误参数回调,流程将停止,所以基本上

if (booltest)
     callback(null, 'one');
else
     callback(true);

应该管用
