如何使用 webdriver 操作用户选择的文本? [英] How to manipulate user selected text using webdriver?

问题描述

假设我的网页中有以下代码段:

Lets say i have the following snippet in my web page:

<p> 这是一些文字 </p>

我希望 WebDriver 在此文本中选择一些"，就好像用户选择了它一样.我该怎么做?我知道如何获得 <p>-element:

I want WebDriver to select "some" in this text, as if the user selected it. How should i do this? I know how to get the <p>-element:

WebElement editable = getDriver().findElement(By.id("someId"));
editable = editable.findElement(By.tagName("p"));
System.out.println(p.getText());

println 打印这是一些文本".

The println prints "This is some text".

我尝试向元素发送密钥，这曾经可以工作(在 selenium 2.0b 中)，但我现在使用的是 selenium 2.6.0，但它停止工作了:

I tried sending keys to the element, and that used to work(in selenium 2.0b), but i'm using selenium 2.6.0 now, and it stopped working:

editable.sendKeys(Keys.chord(Keys.SHIFT, Keys.LEFT));

有人有想法吗?我正在使用 FirefoxDriver.

Does anyone have ideas? I'm using the FirefoxDriver.

推荐答案

我曾使用 Javascript 为 Firefox 做过一次.基本上我在 Firefox 中使用 range 对象来选择文本.根据您要选择的内容更改开始和结束范围索引.这在 IE 中不起作用，因为在 IE 中选择范围在概念上是不同的.我手边没有 IE 代码，但由于您担心 FF，您可以试一试.如果您对 IE 文本范围感兴趣，请告诉我.

I did this once for Firefox using Javascript. Basically I used the range object in Firefox to select the text. Change the start and end range index based on what you want to select. This would not work in IE, because selecting range is conceptually different in IE. I don't have the IE code handy but since you are concerned about FF, you could give this a shot. Let me know if you interested in IE text range.

String script = "var range = document.createRange();" +
"var start = document.getElementById('idofthedivthatcontainstext');" +
"var textNode = start.getElementsByTagName('p')[0].firstChild;" +
"range.setStart(textNode, 8);" +
"range.setEnd(textNode, 13);" +
"window.getSelection().addRange(range);";
 ((JavascriptExecutor)driver).executeScript(script);
