使用量角器不能在不同的浏览器中工作拖放？

Question

我有下面这是在本地机器做工精细的代码，铬环境考虑拖拽：

browser.actions().dragAndDrop(elem1, elem2).mouseUp().perform(); 

但同样的代码在Firefox浏览器中抛出错误詹金斯环境：

[e2e] [firefox #11-1] [31m Failed: UnknownError: Cannot release a button when no button is pressed.'UnknownError: Cannot release a button when no button is pressed.' when calling method: [wdIMouse::up]

任何援助修复将非常感激修复它

Answer 1

我是错的语法：

browser.actions().dragAndDrop(elem1, elem2).mouseUp().perform(); 

应改为：

browser.actions().dragAndDrop(elem1, elem2).perform(); 

Answer 2

尝试做同样没有.mouseUp()，在.dragAndDrop()已经拥有它的情况。

dragAndDrop幕后是鼠标按下+的mouseMove + mouseUp事件：

/** 
* Convenience function for performing a "drag and drop" manuever. The target 
* element may be moved to the location of another element, or by an offset (in 
* pixels). 
* @param {!webdriver.WebElement} element The element to drag. 
* @param {(!webdriver.WebElement|{x: number, y: number})} location The 
*  location to drag to, either as another WebElement or an offset in pixels. 
* @return {!webdriver.ActionSequence} A self reference. 
*/ 
webdriver.ActionSequence.prototype.dragAndDrop = function(element, location) { 
    return this.mouseDown(element).mouseMove(location).mouseUp(); 
};
