如何执行脚本Selenium-TypeError：....未定义

Question

我要执行脚本：

if(driver instanceof JavascriptExecutor) {
((JavascriptExecutor) driver) 
.executeScript("zaznaczKomorke(0,\"\",document.getElementById('TABELA_EIS_0').childNodes[1].childNodes[0].childNodes[0])"); 

}  
if(driver instanceof JavascriptExecutor) {
((JavascriptExecutor) driver) 
        .executeScript("usunK()");}

但是我有错误：

Exception in thread "main" org.openqa.selenium.JavascriptException: TypeError: komorka_EIS is undefined

有人可以帮助我吗？

功能usunK（）代码：

function usunK(){
    var poziomWarstwy = currentRozdzial==""?0:currentRozdzial;
    var tabela = tabelaManager.znajdzElementyPoziomuRozdzialu()[currentTable];
    var tabela_EIS = document.getElementById("TABELA_EIS" + currentRozdzial + "_" + currentTable);
    var rows = parseInt(liczbaWierszy.get(poziomWarstwy)[currentTable]);
    var cols = parseInt(liczbaKolumn.get(poziomWarstwy)[currentTable]);     
    var rowsNaglCount = tabelaManager.getLiczbaWierszyNagl(tabela.rowsNagl);
    var komorka_EIS = selection.getSelectedCell_EIS();
var col = komorka_EIS.col.nr;

问题出在函数usunK（）

zaznaczKomorke函数执行良好，控制台上没有任何错误

任何想法??
