通过带有JavaScript的Python通过Selenium使WebElement可见 [英] Make WebElement visible via Selenium with Python with JavaScript

问题描述

我想通过selenium上传png。我的问题是，我需要使用的输入，是不可见的硒，但不是用户。在Selenium的常见问题中，他们告诉我使用JavascriptExcecutor像：

 （（JavascriptExecutor）driver）.executeScript 0] .style.visibility ='visible'; arguments [0] .style.height ='1px'; arguments [0] .style.width ='1px'; arguments [0] .style.opacity = 1，fileUploadElement ）; 
 

在过去，我用这个与C＃，并且它的工作，但现在im奋斗转换使用到python。我将使用 document.getElementByName（）函数，但输入没有名称，并且在页面上有多个。什么是解决这个问题的最好方法。我已经尝试过

  icon = element.find_element_by_css_selector（input）
 script_befehl = icon +。style.visibility = 'visible';+ icon +。style.height ='1px';+ icon +。style.width ='1px';+ icon +。style.opacity = 1 
  
 
 
 
但是没有效果，我得到一个语法错误
解决方案
有一个  execute_script（） 方法的驱动程序实例，参数传递给它类似于C＃的 JavascriptExecutor ：
  icon = element.find_element_by_css_selector（input）
 driver.execute_script（arguments [0]。 style.visibility ='visible'; arguments [0] .style.height ='1px'; arguments [0] .style.width ='1px'; arguments [0] .style.opacity = 1，icon）
  
 
I'm trying to upload a png via selenium. My Problem is, that the Input I need to use, is invisible to selenium, but not to the user. In the FAQ of Selenium they told me to use the JavascriptExcecutor like:
((JavascriptExecutor)driver).executeScript("arguments[0].style.visibility = 'visible'; arguments[0].style.height = '1px'; arguments[0].style.width = '1px'; arguments[0].style.opacity = 1", fileUploadElement);
I used this with C# in the past, and it worked, but now im struggeling to convert that usage to python. I would use the document.getElementByName() function, but the input doesn't have a Name and there are more than one on the page. What is the best way to solve that Problem. I already tried
icon = element.find_element_by_css_selector("input")
script_befehl = icon+".style.visibility = 'visible'; "+icon+".style.height = '1px'; "+icon+".style.width = '1px'; "+icon+".style.opacity = 1
but that also didn't work, i'm getting a Syntax error
解决方案
There is an execute_script() method on the driver instance, arguments are passed to it in a similar to C#'s JavascriptExecutor:
icon = element.find_element_by_css_selector("input")
driver.execute_script("arguments[0].style.visibility = 'visible'; arguments[0].style.height = '1px'; arguments[0].style.width = '1px'; arguments[0].style.opacity = 1", icon)
