Selenium Java-尝试单击按钮

Question

I am trying to click a button that that has the below HTML.

<button title="XXYZ" class="clsBarButton" id="tbCodeBookI10" hidefocus="true"
    onmouseover="changeTBC(this)" onmouseout="changeTBC(this)" onmousedown="changeTBC(this)"
    onmouseup="changeTBC(this)" onclick="OpenReference('i10codebook'); resyncTabs();" type="button">
</button>

I tried the following different lines in my code but all of them throws no such element.

driver.findElement(By.xpath("//button[@id='tbCodeBookI10' and class='clsBarButton2']")).click()

driver.findElement(By.cssSelector("html body.clsBody.clsAJAXBody div#Toolbar
button#tbCodeBookI10.clsBarButton")).click();

Answer 1

This should work just fine

driver.findElement(By.id("tbCodeBookI10")).click();

If it keeps on failing as you suggest in your comment, check two things, that the HTML is a valid HTML, and that your button is not within an iframe (in which case you would first need to switch to the iframe)

For switching to iframe the following code should work

    driver.switchTo().defaultContent(); 
    WebElement yourIframe = driver.findElement(By.name(*THE NAME OF YOUR IFRAME*));
    driver.switchTo().frame(yourIframe);
