問(wèn)題描述：
　　點(diǎn)擊按鈕出現(xiàn)一個(gè)模態(tài)對(duì)話框，代碼會(huì)卡在click這步不繼續(xù)執(zhí)行。原因是Selenium目前沒(méi)有提供對(duì)模態(tài)對(duì)話框的處理。
　　解決方案：
　　將click出現(xiàn)彈出框這步用JS代替執(zhí)行，然后切換到彈出窗可以繼續(xù)操作頁(yè)面元素了。
　　測(cè)試地址：https://developer.mozilla.org/samples/domref/showModalDialog.html
　　代碼如下：
public class junitTest {
WebDriver driver = new FirefoxDriver();
String baseUrl = "https://developer.mozilla.org/samples/domref/showModalDialog.html";
@Test
public void openModal() throws InterruptedException{
driver.get(baseUrl);
driver.findElement(By.xpath("/html/body/input")).click();    //點(diǎn)擊后代碼卡在這里
Thread.sleep(2000);
Set<String> handlers = driver.getWindowHandles();
for(String winHandler:handlers){
driver.switchTo().window(winHandler);
}
driver.findElement(By.id("foo")).sendKeys("2");
driver.findElement(By.xpath("/html/body/input[2]")).click();
}
}
　　click這步替換為JS執(zhí)行后代碼：
public class junitTest {
WebDriver driver = new FirefoxDriver();
String baseUrl = "https://developer.mozilla.org/samples/domref/showModalDialog.html";
@Test
public void openModal() throws InterruptedException{
driver.get(baseUrl);
//driver.findElement(By.xpath("/html/body/input")).click();    //點(diǎn)擊后代碼卡在這里
String js = "setTimeout(function(){document.getElementsByTagName('input')[0].click()}，100)";
((JavascriptExecutor)driver).executeScript(js);
Thread.sleep(2000);
Set<String> handlers = driver.getWindowHandles();
for(String winHandler:handlers){
driver.switchTo().window(winHandler);
}
driver.findElement(By.id("foo")).sendKeys("2");
driver.findElement(By.xpath("/html/body/input[2]")).click();
}
}
