Java Selenium Webdriver表达式查找以ccs开头和结尾的ccs动态元素 [英] Java Selenium webdriver expression finding dynamic element by ccs that starts with and ends with
问题描述
我有以下需要查找的HTML元素.现在，将这个"id"添加到名称以int"0"表示的方式是动态的.最后会改变，但我知道会是什么."0--0"中的第一个int也会发生变化，但这无关紧要.
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">
我尝试了以下代码，查找以#ui-select-choices-row-"开头的元素.并以所需的"int"输入结尾，但未按预期找到它.关于我在这里做错什么的任何建议吗?
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?
尝试1:
driver.findElement(By.cssSelector("div[id^='#ui-select-choices-row-'] and div[id$='"+int+" div']"));
尝试2:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'] and div[id$='"+int+"']"));
推荐答案
您已经足够亲密.您需要从 id 的开头删除 # ，因为 # 本身表示 id 属性.
You were close enough. You need to remove the # from the beginning of the id as # itself denotes the id attribute.
要仅考虑 href 和 data-drupal-link-system-path 属性的静态部分，可以在
To consider only the static part of href and data-drupal-link-system-path attributes you can use the following wildcards in css-selectors:
-
$ :表示属性值结尾
^ :表示属性值起始于
因此，最精细的css_selector将是:
So the most granular css_selector would be :
div[id^='ui-select-choices-row-'][id$='" +count+ "']
解决方案
您的有效代码行将是:
Solution
Your effective line of code will be:
driver.findElement(By.cssSelector("div[id^='ui-select-choices-row-'][id$='" +count+ "']"));
注意: int 是关键字，使用其他名称作为变量名称.
Note: int is a keyword, use other names as the variable name.
