org.openqa.selenium.NoSuchElementException:尝试通过CssSelector定位card-fields-iframe时，返回的节点(空)不是DOM元素

我正在尝试通过部分ID定位iframe.对于这种方法，我使用了: driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[id*='card-fields-number']")));我也尝试过xpath.

I am trying to locate an iframe by partial id. For this method, I used: driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[id*='card-fields-number']"))); I have also tried xpath.

 driver.switchTo().frame(driver.findElement(By.xpath("//iframe[contains(@id,'card-fields-number')]")));

但是，我仍然收到此异常:

However, I still receive this exception:

org.openqa.selenium.NoSuchElementException: Returned node (null) was not a DOM element

我发现，当我为HtmlUnit启用javascript时，它能够找到框架并切换到该框架.我宁愿不启用javascript，因为它对我来说运行非常缓慢，并增加了不必要的延迟.

I found out that when I enable javascript for HtmlUnit, it is able to locate the frame, and switch to it. I would rather not enable javascript as it runs very slow for me, and adds unneeded delay.

iFrame HTML代码:

iFrame HTML code:

<iframe class="card-fields-iframe" frameborder="0" id="card-fields-number-7pbvqg7azsf00000" name="card-fields-number-7pbvqg7azsf00000" scrolling="no" src="https://checkout.shopifycs.com/number?identifier=438599641d0ed8fe61c161d72e62b5f8&amp;location=https%3A%2F%2Fshopnicekicks.com%2F2192362%2Fcheckouts%2F438599641d0ed8fe61c161d72e62b5f8&amp;dir=ltr&amp;fonts[]=Lato" title="Field container for: Card number" style="height: 43px;"></iframe>

iFrame ID是动态的，因此这就是为什么我使用部分ID的原因.

iFrame ID is dynamic, so that is why I resort to using partial ID.

更新 iFrame在父框架的内部. 父框架:

Update The iFrame is inside of the parent frame. Parent Frame:

<iframe srcdoc="<script>!function(){var e=function(e){var t={exports:{}};return e.call(t.exports,t,t.exports),t.exports},t=function(){function e(e,t){for(var n=0;n<t.length;n++){var i=t[n];i.enumerable=i.enumerable||!1,i.configurable=!0,&quot;value&quot;in i&amp;&amp;(i.writable=!0),Object.defineProperty(e,i.key,i)}}return function(t,n,i){return n&amp;&amp;e(t.prototype,n),i&amp;&amp;e(t,i),t}}(),n=function(e,t){if(!(e instanceof t))throw new TypeError(&quot;Cannot call a class as a function&quot;)},i=function(e){return e&amp;&amp;e.__esModule?e:{&quot;default&quot;:e}},o=e(function(e,i){&quot;use strict&quot;;Object.defineProperty(i,&quot;__esModule&quot;,{value:!0});var o=function(){function e(){var t=this;n(this,e),this.calls=[],window.ga=function(){for(var e=arguments.length,n=Array(e),i=0;i<e;i++)n[i]=arguments[i];return t.gaCall(n)}}return t(e,[{key:&quot;gaCall&quot;,value:function(e){var t=this;this.calls.push(e),clearTimeout(this.timeout),this.timeout=setTimeout(function(){t.calls.length>0&amp;&amp;t.sendMessage()},0)}},{key:&quot;listen&quot;,value:function(){var e=this;window.addEventListener(&quot;message&quot;,function(t){return e.receiveMessage(t)},!1)}},{key:&quot;sendMessage&quot;,value:function(){window.parent.postMessage({type:&quot;analytics&quot;,calls:this.calls},this.origin),this.calls=[]}},{key:&quot;receiveMessage&quot;,value:function(e){if(e.source===window.parent&amp;&amp;&quot;checkout_context&quot;===e.data.type){this.origin=e.origin,window.Shopify=e.data.Shopify,window.__st=e.data.__st;try{window.additionalScripts()}catch(e){console.error(&quot;User script error: &quot;,e)}}}}]),e}();i[&quot;default&quot;]=o});e(function(){&quot;use strict&quot;;var e=i(o);!function(){(new e[&quot;default&quot;]).listen()}()})}(&quot;undefined&quot;!=typeof global?global:&quot;undefined&quot;!=typeof window&amp;&amp;window); window.additionalScripts = function () {};</script>" src="https://checkout.shopify.com/2192362/sandbox/google_analytics_iframe" onload="this.setAttribute('data-loaded', true)" sandbox="allow-scripts" id="google-analytics-sandbox" tabindex="-1" class="visually-hidden" style="display:none" aria-hidden="true" data-loaded="true"></iframe>
