“组件未初始化"； nsresult:"0xc1f30001(NS_ERROR_NOT_INITIALIZED)" Selenium GeckoDriver和Mozilla错误 [英] "Component not initialized" nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" error with Selenium GeckoDriver and Mozilla

问题描述

我试图在Firefox中执行我的代码，有时它可以工作，但大多数情况下我会出现以下异常:

I am trying to execute my code in Firefox, sometimes it works but majority of time i get exception as:

[Exception... "Component not initialized"  nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)"  location: "JS frame :: chrome://marionette/content/dom.js :: addEventListener :: line 67"  data: no]

它从上周开始发生，以前对我来说还不错.

Its happening from last week, previously it was working fine for me.

推荐答案

NS_ERROR_NOT_INITIALIZED 类似于尝试使用尚未初始化的组件或对象.这些组件通常提供一个初始化方法，通常称为Init，必须在使用任何其他方法之前调用它.

NS_ERROR_NOT_INITIALIZED resembles an attempt which was made to use a component or object which has not yet been initialized. These components usually provide an initialization method, often called Init which must be called before any other methods which are being used.

但是，此错误消息...

However, this error message...

[Exception... "Component not initialized"  nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)"  location: "JS frame :: chrome://marionette/content/dom.js :: addEventListener :: line 67"  data: no]

...表示牵线木偶在调用 dom.js

...implies that the Marionette threw an error while invoking addEventListener as defined in dom.js

您的代码试用版和相关的 HTML DOM 可以帮助我们调试以更好的方式发行.但是，似乎addEventListener甚至在完全呈现 DOM树之前就被调用为时过早.更具体地说，甚至在 Browser Client (即Web浏览器)达到'document.readyState'等于"complete"之前，就调用了addEventListener.通常，一旦满足此条件， Selenium 执行下一个代码行.

Your code trials and the relevant HTML DOM would have helped us to debug the issue in a better way. However it seems the addEventListener was invoked too early even before the DOM Tree was completely rendered. To be more specific addEventListener was invoked even before the Browser Client (i.e. the Web Browser) have attained 'document.readyState' equal to "complete". Generally once this condition is fulfilled Selenium performs the next line of code.

一种快速的解决方案是，在尝试与新加载的网页上的任何元素进行交互之前，您需要为以下两个WebDriverWait seleniumhq.github.io/selenium/docs/api/py/webdriver_support/selenium.webdriver.support.expected_conditions.html#module-selenium.webdriver.support.expected_conditions"rel =" nofollow noreferrer>期望的条件:

A quick solution will be to before you try to interact with any of the element on a fresh loaded webpage you need to induce WebDriverWait for either of the following expected_conditions:

• title_is(title)
• title_contains(title)

• Python :

• 代码块:

• Code Block:

driver.get("https://stackoverflow.com");
WebDriverWait(driver, 10).until(EC.title_contains("Stack"))
print("Page Title is : "+driver.title)

控制台输出:

Console Output:

Page Title is : Stack Overflow - Where Developers Learn, Share, & Build Careers 

Java :

• 代码块:

• Code Block:

driver.get("https://stackoverflow.com");
new WebDriverWait(driver, 10).until(ExpectedConditions.titleContains("Stack"));
System.out.println("Page Title is : "+driver.getTitle());

控制台输出:

Console Output:

Page Title is : Stack Overflow - Where Developers Learn, Share, & Build Careers
