《SeleniumBasic 3.141.0.0

SeleniumBasic中的Actions类可以实现鼠标和键盘操作。方法列表如下

其中标记为橙色的是键盘方面的操作。标记绿色的Create方法是创建行为时必须要运行的。

• Function Click([onElement As IWebElement]) As Actions
• Function ClickAndHold([onElement As IWebElement]) As Actions
• Function ContextClick([onElement As IWebElement]) As Actions
• Sub Create(driver As IWebDriver)
• Function DoubleClick([onElement As IWebElement]) As Actions
• Function DragAndDrop(source As IWebElement, target As IWebElement) As Actions
• Function DragAndDropToOffset(source As IWebElement, offsetX As Long, offsety As Long) As Actions
• Function KeyDown(theKey As String, [onElement As IWebElement]) As Actions
• Function KeyUp(theKey As String, [onElement As IWebElement]) As Actions
• Function MoveByOffset(offsetX As Long, offsety As Long) As Actions
• Function MoveToElement(toElement As IWebElement, [offsetX As Long], [offsety As Long]) As Actions
• Sub Perform()
• Function Release_([onElement As IWebElement]) As Actions
• Function Sendkeys(keysToSend As String, [element As IWebElement]) As Actions

执行行为链时必须运行Perform方法，否则没有效果。

可以看到均有一个element可选参数，这个可以提供，也可以不写。

下面的程序，演示了在搜索中按下右键，弹出快捷菜单。

    Dim Action As SeleniumBasic.Actions
    Set Action = New SeleniumBasic.Actions
    Action.Create driver:=WD
    Action.ContextClick(onElement:=keyword).Perform

WD是浏览器对象，通过Action.Create方法与之关联。运行ContextClick方法，会在元素上按下右键。对于单击、双击都是相同的用法，不需举例。

按键方面，可以使用KeyDown按下Control、Shift或功能键，也可以使用KeyUp弹起。

还可以使用SendKeys发送字符串。下面程序演示了创建行为链，向百度搜索框中发送Control+A全选，然后发送Control+X剪切。这样就把文本框的内容剪切到剪贴板上了。

    Dim Key As SeleniumBasic.Keys
    Dim Action As SeleniumBasic.Actions
    Set Key = New SeleniumBasic.Keys
    Set Action = New SeleniumBasic.Actions
    Action.Create driver:=WD
    Call Action.KeyDown(Key.Control, keyword).SendKeys("a", keyword).KeyUp(Key.Control, keyword).KeyDown(Key.Control, keyword).SendKeys("x", keyword).KeyUp(Key.Control, keyword).Perform
