从if语句块中退出

Question

我正在使用nuxt.js和javascript，并且我正在处理一个表单reCaptcha方法，并且我有一系列的if statements，我需要通过它们才能进入需要的条件块。

我怎样才能在任何阶段都能最好地写出这个代码块，并在每次都不需要写else (重定向错误)的情况下把它们弄错呢？

遍历每个块，如果失败了就把它们扔出去？

        if(sauhp.length < 1){
                //sauhp is empty and not a bot - proceed
                const token = await this.$recaptcha(formType);
                //Send the token to validate
                let verifyReCaptcha = await axios.get('/api/recaptcha/api/siteverify?secret='+secret+'&response='+token);
                let reCaptchaResponse = verifyReCaptcha.data;
                //Validate the action
                if(reCaptchaResponse.action === formType){
                    //Process the form
                    if(reCaptchaResponse.score > 1){
                        console.log('yes great go ahead')
                    }else{
                    window.$nuxt.error({ 
                            statusCode: 500, 
                            message: "We've detected a problem in the form submission. Call us, we're here to help."
                        }) 
                    }
                }
            }else{
                window.$nuxt.error({ 
                    statusCode: 500, 
                    message: "We've detected a problem in the form submission. Call us, we're here to help."
                })
            }
        },

Answer 1

对Error执行throw操作，并在if之外执行catch (MDN)操作：

try {
  // your if block ... 
  throw new Error('error message');
  // ...
} catch (error) {
   window.$nuxt.error({ 
     statusCode: 500, 
     message: error.message
   });
}

当然，如果您收到相同的错误消息，只需对其进行硬编码，然后简单地使用throw new Error();或任何其他方法即可

您可以像下面这样修改代码

if(sauhp.length < 1){
                //sauhp is empty and not a bot - proceed
                const token = await this.$recaptcha(formType);
                //Send the token to validate
                let verifyReCaptcha = await axios.get('/api/recaptcha/api/siteverify?secret='+secret+'&response='+token);
                let reCaptchaResponse = verifyReCaptcha.data;
                //Validate the action
                if(reCaptchaResponse.action === formType && reCaptchaResponse.score > 1){
                    console.log('yes great go ahead')
                    return true;
                }
            }
            window.$nuxt.error({ 
                            statusCode: 500, 
                            message: "We've detected a problem in the form submission. Call us, we're here to help."
                        }) 
            }
        },
