Excel 自定义实现Contains函数,在Excel中,我们经常需要检查一个单元格是否包含一个特定的值。但除了非空单元格检查外,没有任何默认的内置函数用于检查单元格是否包含一个值或数字、特定文本或任何其他值。本文介绍了三种方法实现Contains功能,检查单元格中是否包含指定文本。
function regexpContains(text, pattern) { return new RegExp(pattern).test(text); } // 使用示例 const text = "Hello, world!"; const pattern = /world/; console.log(regexpContains(text, pattern)); // 输出: true SQL (PostgreSQL)

In the following program, we are instantiating the string class with the value"Java Programming". Then, we are creating the char sequence with the value"Java". Using thecontains()method, we are trying to check whether the given string contains the specified char sequence or not. ...
Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map ...

Learn how to use the JSTL function 'contains' in JSP to check if a string contains a specific substring. Enhance your JSP applications with this effective function.
One of the nasty little traps a Java developer can run into occurs when Collection.contains(Object) is not used with appropriate understanding. I demonstrate this potential trap in this post.
