selenium: find the right button but fail to click by using className

Question

I try to find the button by using two way. The first by the xpath directly which is working. But the second way is not working. after using the click() function nothing happen and no error.

First way:

By.xpath(".//*[@id='app:viewAppInsideConfirm:confirmInside:j_id300']").click()

Second way:

By.className("iceCmdBtn").click()

html:

<input id="app:viewAppInsideConfirm:confirmInside:j_id300" class="iceCmdBtn" type="submit" value=" Yes " onfocus="setFocus(this.id);" onclick="parent.JSsessionTimeOut.resetSessionTimeout();iceSubmit(form,this,event);return false;" onblur="setFocus('');" name="app:viewAppInsideConfirm:confirmInside:j_id300"></input>

BTW:

I try to use xpath to find different items, I got:

Use 'sumbit' as key word can find it, but same as the By.className("iceCmdBtn") Find but with click() no action...

  String xpathLocater = ".//*[@type='submit']"; 
  driver.findElement(By.xpath(xpathLocater)).click();

For the ' Yes ' , I got error to find the element...

String xpathLocater = ".//*[@value=' Yes ']"; driver.findElement(By.xpath(xpathLocater)).click();

Guys!!!

It have another button:

So I guess I need use FindElements

假设示例中id的动态部分为300 ，则可以使用starts-with()进行部分检查：

By.xpath(".//input[starts-with(@id, 'app:viewAppInsideConfirm:confirmInside:') and @class='iceCmdBtn']").click()
