watir-webdriver - 单击 Javascript 按钮 [英] watir-webdriver - clicking Javascript button

问题描述

第一周一般是 watir-webdriver 和 Web 应用程序测试，因此仍在尝试围绕一些概念.

First week with watir-webdriver and Web app testing in general, so still trying to wrap some concepts around.

有这个 javascript 元素:

Having this javascript element:

<input type="submit" class="button" value="Search" name="_target0">

browser.button(:value, "Search").exists?
=> "true"

browser.button(:value, "Pesquisar").present?
=> true

browser.button(:name, "_target0").value
=> "Search"

这实际上并没有促使按钮被点击，

This doesn't actually drive the button to get clicked,

browser.button(:name, "_target0").click

所以我让驱动的 Firefox 使用任一按钮点击按钮

So I got the driven Firefox clicking the button using either

browser.button(:name, "_target0").fire_event('on_click')
browser.button(:name, "_target0").when_present.click

但它们之间有什么区别?

but what are the differences between them?

推荐答案

至于它们之间的区别:

• .click = 模拟鼠标左键单击对象.
• .fire_event= 执行一个 javascript，即使它可能会或可能无法通过鼠标点击正常访问.
• when_present.click = 等待对象既可用又出现在可视区域(完整的浏览器窗口)，然后再尝试点击.

• .click = simulates a left mouse click on the object.
• .fire_event = executes a javascript even that may or may not be accessible normally via mouse click.
• when_present.click = waits for the object to be both available and appear in the viewable area (full browser window) before it attempts to click.

when_present 在您的站点使用 AJAX 并且与一个对象交互导致另一个对象最终出现时很有用.使用 .click 可能会尝试在第二个对象可用之前单击它，并且脚本将失败.

when_present is useful for when your site uses AJAX, and interacting with one object causes another object to eventually appear. Using a .click may attempt to click the second object before it is available, and the script will fail.

您的页面可能包含 AJAX 表单，并且您尝试与之交互的按钮不会立即加载，而是会在以下情况下短暂延迟加载:

It is likely that your page contains an AJAX form, and the button you are attempting to interact with does not load immediately, but after a short delay when:

• 输入了一个文本字段
• 点击了另一个按钮
• 页面完成生成内容
• 等

由于 fire_event 不查找按钮的物理表示，而是查找源中的 JS 事件，因此它可以在按钮出现/可见/可操作之前使用.

Since fire_event does not look for the physical representation of the button, but rather the JS event in the source, it can be used before the button is present/visible/actionable.
