Selenium Webdriver：如何单击这些链接？

Question

<a onclick="requestReportGeneration('857f23e1baa767622a91f970963d8918', 'reportDiv31','CSV')" href="javascript:void[0];">CSV</a>
<a onclick="requestReportGeneration('64107e36323e5877c986edc98a17b6e8', 'reportDiv32','CSV')" href="javascript:void[0];">CSV</a>
<a onclick="requestReportGeneration('2cad4d4e5c8855c47a88b6ddf8345735', 'reportDiv33','CSV')" href="javascript:void[0];">CSV</a>

I have these three links on a page and I want to click each one in turn. I am reading all the links on the page into a list of WebElements and then I go through each one in turn if the href contains javascript:void[0] I then try to click it:

for (int i = 0; i < allLinks.size(); i++) {
    String reportLink = allLinks.get(i).getAttribute("href");

    if (reportLink.contains("javascript:void[0];")) 
    {
        allLinks.get(i).click();
        /// Do some more stuff
    }

The problem is I keep getting an error saying the element is not visible. I have also tried just loading the page and instead of getting all the links doing

driver.findElement(By.xpath("//a[contains(@href,\"javascript:void[0]\")]")).click();

but that also just gives element not visible error. Can anybody tell me why this isn't working?

Try putting a breakpoint before the while loop, debug your script, then step into it and use Eclipse's Display tab to interrogate what is up with the links. Try evaluating sample statements like:

allLinks.size();
allLinks.get(i).isDisplayed();
allLinks.get(i).isEnabled();

There must be something odd about the links (or the way webdriver is seeing them), but debugging like this will let you find out what it is.
