如何在Vue组件中添加grecaptcha onload方法.未加载时grecaptcha.render不是函数

how to add grecaptcha onload method in Vue component.when not loaded grecaptcha.render is not a function

const script = document.createElement("script");
 script.src = `${URL}?render=explicit&hl=TR`;
 script.async = true;
 script.defer = true;
 document.body.appendChild(script);
 this.initReCaptcha();


initReCaptcha: function () {
    setTimeout(function () {
       if (typeof grecaptcha === 'undefined') {
           this.initReCaptcha();
       } else {
          grecaptcha.render('recaptcha', {
          sitekey: 'XXXX',
          callback: this.submit,
          'expired-callback': this.expired
                        });
                    }
                }.bind(this), 100);
            }

当我将超时设置为 1000 时正在工作.但为时已晚.

is working when i set the timeout 1000.but it's too late.

推荐答案

recaptcha 脚本已于去年 May 4, 2018 9:07:30.349 PM GMT 更新(基于 recaptcha 脚本的时间戳).grecaptcha 正在加载，但是渲染函数有延迟，这就是为什么在 UI 中没有显示 recaptcha(grecaptcha.render 不是函数n).可能的解决方法是在尝试加载 recaptcha 之前验证 render 函数.

The recaptcha script was updated last May 4, 2018 9:07:30.349 PM GMT (based on the timestamp of the recaptcha script). The grecaptcha is being loaded, however the render function has a delay that is why the recaptcha is not being displayed in the UI (grecaptcha.render is not a function). The possible fix is to validate the render function before attempting to load the recaptcha.

修复方法如下:

initReCaptcha: function () {
    setTimeout(function () {
        if (typeof grecaptcha === 'undefined' || typeof grecaptcha.render ==='undefined') {
            this.initReCaptcha();
        } else {
            grecaptcha.render('recaptcha', {
                sitekey: 'XXXX',
                callback: this.submit,
                'expired-callback': this.expired
            });
        }
    }.bind(this), 100);
}

希望能帮到你.干杯
