获取此链接地址中pointId数值 ‘http://192.168.110.74/saasbasic/app/point//QRCode?companyCode=666666&pointId=123456’

从您提供的链接地址中提取`pointId`的数值,可以通过解析URL中的查询参数来完成。URL的查询字符串位于`?`之后,以`&`分隔各个参数,每个参数都是`key=value`的格式。在您给出的例子中:
`http://192.168.110.74/saasbasic/app/point//QRCode?companyCode=666666&pointId=123456`
我们可以看到有两个参数:`companyCode`和`pointId`。其中`pointId`的值是`123456`。
在编程语言中,例如Python,可以通过使用标准库中的`urllib.parse`模块来解析这个URL并获取`pointId`的值:
```python
from urllib.parse import urlparse, parse_qs
url = "http://192.168.110.74/saasbasic/app/point//QRCode?companyCode=666666&pointId=123456"
parsed_url = urlparse(url)
query_params = parse_qs(parsed_url.query)
pointId_value = query_params.get('pointId', [None])[0]
```
在这段代码中,`pointId_value`将会是`'123456'`,因为它对应的值在查询参数中。

使用js获取此链接地址中pointId数值 ‘http://192.168.110.74/saasbasic/app/point//QRCode?companyCode=666666&pointId=123456’
在JavaScript中,你可以使用`window.location`对象来获取当前URL的各个部分。如果你想从给定的URL中提取`pointId`的数值,你可以使用`URLSearchParams`对象来解析查询字符串,然后获取`pointId`对应的值。以下是获取`pointId`的具体步骤:
1. 使用`window.location.href`获取当前页面的完整URL。
2. 使用`URL`构造函数创建一个URL对象,这将允许你使用`URLSearchParams`。
3. 使用`URLSearchParams`对象的`get`方法来获取`pointId`的值。
下面是具体的代码示例:
```javascript
// 假设这是当前页面的URL
const url = 'http://192.168.110.74/saasbasic/app/point//QRCode?companyCode=666666&pointId=123456';
// 创建URL对象
const currentUrl = new URL(url);
// 使用URLSearchParams获取查询字符串
const searchParams = new URLSearchParams(currentUrl.search);
// 获取pointId的值
const pointId = searchParams.get('pointId');
// 输出pointId的值
console.log(pointId); // 输出: 123456
```
请确保这段代码在浏览器环境中运行,因为`window.location`和`URL` API是浏览器特有的。
