我想實現一個CTA窗體的內容異步加載的Bootstrap模式。 因此,無論何時我打開模態,其內容都會動態生成並插入到模態中。Boostrap Ajax模式與谷歌reCaptcha - 呼叫captcha挑戰不工作兩次
要呈現驗證碼,我使用Bootstrap模態的打開事件。基本上,我只適用於當模式的內容lodaed並顯示驗證碼:
self.$modal.on('shown.bs.modal', function() {
$('.bootstrap.modal-backdrop.fade.in').css("z-index", 1059);
var form = $("#cta-modal-holder form.callToAction");
var captchaCheckNeeded = form.attr('data-captcha');
//Check if we need to apply captcha on the form
if (captchaCheckNeeded.toLowerCase() == 'true') {
//This apply the render() method on the form using an invisible <div>
IMD.Website.Cms.GoogleCaptcha(form[0]);
}
});
直到這裏,沒有煩惱,驗證碼圖標中顯示的驗證碼的頁面下角而被呈現,以及應用在形成。然後,我只想在表單在客戶端有效時觸發驗證碼挑戰。所以基本上,按鈕上的單擊事件,我首先檢查的形式是完全有效之前調用grecaptcha.execute()方法:
$.when($form.isFormValidAsync()).then(function (isValid) {
//First we perform the classic form client validation, only if this IsValid, then we perform the captcha validation
if (isValid) {
//If captchaCheckNeeded == true, then we execute the Captcha
//Here, two behaviours possible from client side :
// - 1. User is not suspected as a BOT, captcha check is executed and return the token transparently from the user and form is sent automatically
// - 2. User is suspected as a BOT, then the captcha modal is showed to the visitor that has to fill the captcha challenge.
// Only when the challenge is validated, then the form is sent because of the Captcha callback function.
if (captchaCheckNeeded.toLowerCase() == 'true') {
var holder = $form[0].querySelector('.recaptcha-holder');
grecaptcha.execute(holder[0]);
$submitBtn.prop('disabled', false);
}else{
$form.trigger('submit', { buttonSubmit: true });
}
} else {
這工作完全在第一模開幕。問題是當我關閉模式然後重新打開它時,captcha.render()完成了這項工作,但是當在客戶端驗證之後嘗試發送表單時,grecaptcha.execute()不再向用戶提出挑戰。
我確定captcha方法已經很好地應用並且使用了正確的ID,因爲它在第一時間完美地工作。 在谷歌API方面的細節看多了,我constat當我嘗試的ReCaptcha API以下錯誤只是呈現的驗證碼後第二次使用的GetResponse():
遺漏的類型錯誤:無法讀取屬性的價值「空
事實上,在下面的代碼:
var Do = function(a) {
var b = window.___grecaptcha_cfg.clients[a || 0];
if (!b)
throw Error("Invalid ReCAPTCHA client id: " + a);
return vg(qo(b.id)).value
}
//Here, vg(qo(b.id)) represents the field g-recaptcha-response at the first
call of the getResponse() method.
//At the second call, this value is null, even if I clearly see the field in
my form after calling the render() method.
那麼這個塊我的形式,從來沒有TRIGG驗證碼挑戰的發送。
讓我確切地說,我試圖在模式結束時重置驗證碼,這很好地應用,但這不會改變問題。
我儘量做到儘可能清楚,不容易總結這類問題,任何幫助將不勝感激。
最好的問候,
