button - click() on css Selector not working in Selenium webdriver

Question

HTML

<input class="button" type="button" onclick="$.reload('results')" value="Search">

I don't have an id or name for this . Hence am writing

FirefoxDriver driver = new FirefoxDriver();
driver.get("http://....");
driver.findElement(By.cssSelector("input[value=Search]")).click();

But click() is not happening.

Tried driver.findElement(By.cssSelector(".button[value=Search]")).click();

Tried value='Search' (single quotes).

these Selectors are working in

.button[value=Search] {
padding: 10px;
}
input[value=Search] {
padding: 10px;
}

Answer 1

i would inject piece of js to be confident in resolving this issue:

first of all locate element using DOM (verify in firebug):

public void jsClick(){

        JavascriptExecutor js = (JavascriptExecutor) driver;
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("document.getElementsByTagName('button')[0].click();");
        js.executeScript(stringBuilder.toString());
    }
jsClick();

from the retrospective of your element it be like:

....
stringBuilder.append("document.getElementsByTagName('input')[0].click();");
....

Please, note: document.getElementsByTagName('input') returns you an array of DOM elements. And indexing it properly e.g. document.getElementsByTagName('input')[0], document.getElementsByTagName('input')1, document.getElementsByTagName('input')[2].... ,etc you will be able to locate your element.

Hope this helps you. Regards.
