python - selenium execute_script 给出错误

Question

我正在尝试使用python的selenium包执行网页的javascript功能

我想点击行值

<tr bgcolor="#FFFFFF" style="cursor:hand" 
      onmouseover="onmouseoverTR(this)" 
      onmouseout="onmouseoutTR(this)"         
      onclick="clearwsInfo('2015011800017','2015011800017',this);"
      ondblclick='doSelect("auditflowForm","2015011800017");'>   

作为

function  clearwsInfo(tmpdjbh,tmpsgbh,obj)
{  
    //判断yesnot existentTR已被existent，如果yes就还原到原来的样式
    if ( obj !=""  && obj !=null  )
    {  
        if(preTR!=""){

            preTR.style.background='#FFFFFF';

        }   

        obj.style.background='#c9e3ef';

        preTR=obj;
    }

     var forms = "parent.document." + gFormName + ".";

     parent.document.getElementById("tmpsgbh").value = tmpsgbh;    
     parent.document.getElementById("tmpdjbh").value = tmpdjbh;   

     loadDwr(tmpdjbh,tmpsgbh) ; 

     parent.document.wsList.location.href = "http://114.255.167.200:8092/cidasEN/extend/wsTreeAction.do?cs=1&sgbh="+ tmpsgbh;
} 

我试过的代码是

iedriver = 'C:\Users\IEDriverServer.exe'
browser = webdriver.Ie(iedriver)
browser.get   ('http://114.255.167.200:8092/cidasEN/extend/LookAuditflowListAction.do')
browser.execute_script("clearwsInfo('2015011800017','2015011800017',this)")

我遇到了一个错误

Traceback (most recent call last):
 File "D:\surendra\Neon-WorkSpace\EvidenseData\selinum.py", line 25, in   <module>
  browser.execute_script("clearwsInfo ('2015011800017','2015011800017',this)")

如何执行clearwsInfo函数

Answer 1

也许您只需点击 TR 元素，让 JavaScript 完成剩下的工作，就像人机交互一样。

iedriver = 'C:\Users\IEDriverServer.exe'
browser = webdriver.Ie(iedriver)
browser.get   ('http://114.255.167.200:8092/cidasEN/extend/LookAuditflowListAction.do')
tr = browser.find_element_by_xpath("//table[@class='font9']//tr[contains(@onclick, 'clearws')]")
tr.click()
