是否可以通过Selenium中的部分ID匹配来定位元素
问题描述：
我正在尝试查找具有生成的ID的元素，其中ID的某些部分是已知的；例如:
I am trying to locate elements with generated ids wherein some part of the ID is known; for example:
id="page_x002e_x0023_default-create-firstname"
，其中后3个字(_default-create-firstname)是已知的，但前面的任何内容都可能更改. 这可能吗?
in which the last 3 words (_default-create-firstname) are known but anything preceding that is subject to change. Is this possible?
答
您可以应用 以 CSS选择器结尾:
You can apply an ends-with CSS selector:
By.cssSelector("[id$=default-create-firstname]")
更新
自从答案发布以来，已经过去了一段时间.这里是链接的mozilla开发人员页面的一些更新，以及以下注释:
Some time went by since the answer was posted. Here some update from the linked mozilla developer page and comments below:
新使用By.css代替By.cssSelector
New use By.css instead of By.cssSelector
By.css("[id$=default-create-firstname]")
还可以看到
- 始于
- 里面的任何地方
- 任何大写字母在里面的任何地方
- 结尾
/* Internal links, beginning with "#" */
a[href^="#"] {
background-color: gold;
}
/* Links with "example" anywhere in the URL */
a[href*="example"] {
background-color: silver;
}
/* Links with "insensitive" anywhere in the URL,
regardless of capitalization */
a[href*="insensitive" i] {
color: cyan;
}
/* Links that end in ".org" */
a[href$=".org"] {
color: red;
}
