Selenium WebDriver Java 定位两个不同的表格单元格

Question

I'm using Selenium Webdriver in Java. I have a table, and I like to get my hands on the last cell on the first row, and the last cell of last row. I manage to get one of them

WebElement table =driver.findElement(By.className("dataTable"));
List <WebElement> rows = table.findElements(By.tagName("tr"));
WebElement firstrow= rows.get(0);
WebElement lastrow= rows.get(rivit.size()-1); 
List <WebElement> firstcells = firstrow.findElements(By.tagName("td"));
List <WebElement> lastcells = lastcell.findElements(By.tagName("td"));

firstcell.get(6).getText());

This is because I'm locating td-tags twice. Any hints how to get both cells nicely? I have no identifiers in my rows or cells.

Answer 1

You can use xpath to get the elements:

WebElement lastCellInFirstRow = driver.findElement(By.xpath("table[@class='dataTable']//tr[1]//td[last()]"));
WebElement lastCellInLastRow = driver.findElement(By.xpath("table[@class='dataTable']//tr[last()]//td[last()]"));

Here's the xpath specification . You can play with xpath here .

Answer 2

You can try to make it with cssSelectors:

String cssLast="table[class='dataTable']>tr:first-child>td:last-child"
String cssFirst="table[class='dataTable']>tr:last-child>td:last-child"

it will be smt like that;

driver.findElement(By.cssSelector(cssLast)).getText();
driver.findElement(By.cssSelector(cssFirst)).getText();

another approach is using js:

String getText(cssSel){
 JavascriptExecutor js = (JavascriptExecutor) driver;
        StringBuilder stringBuilder = new StringBuilder();

stringBuilder.append("var x = $(\""+cssSel+"\");");
        stringBuilder.append("return x.text().toString();")       ;


       String res= (String) js.executeScript(stringBuilder.toString());
}

text1=getText(cssLast);
text2=getText(csscssFirst);

But always make sure that you located elements properly (eg using firepath, firebug addon in firefox)

The TableDriver extension ( https://github.com/jkindwall/TableDriver.Java ) offers a nice clean way to handle things like this. If your table has headers, you can (and should) identify the cell column by its header text, but in case you don't have headers, you can still do something like this.

Table table = Table.createWithNoHeaders(driver.findElement(By.className("dataTable")), 0);
WebElement firstRowLastCell = table.findCell(0, table.getColumnCount() - 1);
WebElement lastRowFirstCell = table.findCell(table.getRowCount() - 1, table.getColumnCount() - 1);
