selenium execute_script gives error

I am trying to execute the javascript function of webpage using the selenium package of python

I would like to click on row value

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

function as

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;
}

code which I tried is

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)")

I got an error

Traceback (most recent call last):

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
