Safy平台中，为QA准备的selenium python的driver API，因为QA都习惯使用python在selenium中写单侧，所以创建JS版本的，方便QA写单侧。

safy-selenium-python-driver-usage.js

//driver这个对象是内置的，在编写单侧代码的时候直接调用即可，它包含上面罗列的方法，上面的方法调用后，
//返回一个webElement的对象，webElement还可以继续调用上面的方法，获取子元素、获取属性值、each、click、submit等更多的操作

//driver.find_element_by_id()
var input = driver.find_element_by_id("kw");
should(input.get_attribute("value")).be().equal("123").error("xxxx");

//driver.find_element_by_name()
//获取一个name
var input = driver.find_element_by_name("kw");
should(input.get_attribute("value")).be().equal("123").error("xxxx");

//获取多个name
var inputs = driver.find_elements_by_name("user");
inputs.each(function(index,item){
    should($(item).val()).be().equal("123").error("xxx");
})

//driver.find_element_by_tag_name()
//获取第一个select控件
var selectElement = driver.find_element_by_tag_name("select");
var optionsElement = selectElement.find_element_by_tag_name("option");
optionsElement.each(function(index,item){
    // code here ...
});

//driver.find_element_by_class_name()
var inputElement = driver.find_element_by_class_name(".kw");
inputElement.send_keys("123");
inputElement.click();
// or
var formElement = driver.find_element_by_class_name(".myform");
forElement.submit();

//driver.find_element_by_link_text()
// HTML : <a href="http://www.baidu.com">baidu link</a>
var link = driver.find_element_by_link_text("baidu link");
link.get_attribute("href");

//driver.find_element(By.CSS_SELECTOR,"xxx")
/*
 * By现在有下面几种类型，对应着上面的方法：
 * ID,NAME,CLASS_NAME,TAG_NAME,LINK_TEXT,PARTIAL_LINK_TEXT,CSS_SELECTOR,XPATH
 */
var exampleElement = driver.find_element(By.CSS_SELECTOR,"#example");
//获取#example下面的全部div子元素
exampleElement.find_elements(By.TAG_NAME,"div").each(function(index,item){
    // code here ... 
});
// 其他By的例子同上

//driver.execute_script()
var labels = driver.find_elements_by_tag_name("label");
var inputs = driver.execute_script(
    "var labels = arguments[0],inputs = [];" + 
    "for(var i =0; i < labels.length; i++){" + 
    "   inputs.push(document.getElementById(labels[i].getAttribut('for')));" + 
    "}" +
    "return inputs;",
    labels.get_elements() //获取到DOM元素的集合
);
