java - Selenium html webdriver 无法定位元素

Question

我尝试四处寻找这个错误，但大多数时候问题是拼写错误，我三次检查了我的拼写。 所以问题就在这里。我想浏览一个网站。我有这个作为我的代码:

WebDriver driver = new HtmlUnitDriver();
driver.get("http://genome.ucsc.edu/cgi-bin/hgTables");
WebElement element = driver.findElement(By.name("hgta_doFilterPage"));
element.submit();
WebElement filter = driver.findElement(By.name("hgta_fil.v.hg19.refGene.name.pat"));
filter.sendKeys("");

我尝试访问列出的网站，进入“过滤器”页面部分，单击“创建”，然后在下一页的“名称”部分中输入一些值，然后再次提交。 但我收到此错误:

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element with name: hgta_fil.v.hg19.refGene.name.pat

我仔细检查了页面上的命名:view-source:http://genome.ucsc.edu/cgi-bin/hgTables 并发现:

<TR VALIGN=BOTTOM align='left'><TD colspan=2> name </TD><TD>
<SELECT NAME='hgta_fil.v.hg19.knownGene.name.dd' class='normalText' style='width: 76px' >
<OPTION SELECTED>does</OPTION>
<OPTION>doesn't</OPTION>
</SELECT>
</TD><TD>match </TD><TD>
<INPUT TYPE=TEXT class='inputBox' NAME="hgta_fil.v.hg19.knownGene.name.pat" style='width: 140px' VALUE="*">
&nbsp; </TD></TR>
<TR VALIGN=BOTTOM align='left'><TD colspan=2> chrom </TD><TD>
<SELECT NAME='hgta_fil.v.hg19.knownGene.chrom.dd' class='normalText' style='width: 76px' ><!-- Here -->
<OPTION SELECTED>does</OPTION>
<OPTION>doesn't</OPTION>
</SELECT>
</TD><TD>match </TD><TD>

我想知道是否因为网络驱动程序不再指向正确的站点而遇到此问题？

源中的输入框的名称为 hgta_fil.v.hg19.knownGene.name.pat，但您正在搜索名称为 hgta_fil.v.hg19.refGene 的元素.name.pat.
