问题描述
我需要找到以下 HTML 元素.现在，这个id"name 是动态的，就像 int 0";最后会改变，但我知道它会是什么.0-0"中的第一个 int也会改变，但会是什么都无所谓.
我尝试了下面的代码来查找以#ui-select-choices-row-"开头的元素.并以所需的int"输入结束，但没有按预期找到它.关于我在这里做错了什么有什么建议吗?
尝试 1:
driver.findElement(By.cssSelector("div[id^='#ui-select-choices-row-'] 和 div[id$='"+int+"div']"));
尝试 2:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'] and div[id$='"+int+"']"));
解决方案 你已经足够接近了.您需要将 id 开头的 # 删除为 # 本身表示 id 属性.
动态 CSS_SELECTOR 的解释
要仅考虑 href 和 data-drupal-link-system-path 属性的静态部分，您可以在 css-selectors:
$ :表示一个属性值以
结尾^ : 表示一个属性值以
开头
所以最细粒度的 css_selector 应该是:
div[id^='ui-select-choices-row-'][id$='"+count+ "']
解决方案
您的有效代码行将是:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'][id$='"+count+"']"));
注意:int为关键字，变量名使用其他名称.

I have the below HTML element that I need to find. Now, this "id" name is dynamic in the way that the int "0" at the end will change, but I know what it will be. The first int in "0-0" will also change, but it doesn't matter what it will be.
<div id="ui-select-choices-row-0-0">
I've tried the below code that looks for an element that starts with "#ui-select-choices-row-" and ends with the desired input of "int", but it's not finding it as expected. Any suggestions on what I'm doing wrong here?
Attempt 1:
driver.findElement(By.cssSelector("div[id^='#ui-select-choices-row-'] and div[id$='"+int+" div']"));
Attempt 2:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'] and div[id$='"+int+"']"));
解决方案 You were close enough. You need to remove the # from the beginning of the id as # itself denotes the id attribute.
Explanation of the dynamic CSS_SELECTOR
To consider only the static part of href and data-drupal-link-system-path attributes you can use the following wildcards in css-selectors:
$ : To indicate an attribute value ends with
^ : To indicate an attribute value starts with
So the most granular css_selector would be :
div[id^='ui-select-choices-row-'][id$='" +count+ "']
Solution
Your effective line of code will be:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'][id$='" +count+ "']"));
Note: int is a keyword, use other names as the variable name.
