let str1 = "Hello"; let str2 = "hello"; if (str1.toLowerCase() === str2.toLowerCase()) { console.log("Strings are equal (case-insensitive)"); } else { console.log("Strings are not equal"); } 通过以上方法,可以有效地处理JavaScript中字符串相等性的判断。
例如,在JavaScript中: ``` const str1 = "Hello, world!"; const str2 = "Hello, world!"; if (str1 == str2) { console.log("Two strings are equal."); } else { console.log("Two strings are not equal."); } ``` 在这个例子中,我们定义了两个string类型的变量,分别赋值为“Hello, ...
总之,在JavaScript中进行字符串比较时,推荐使用 === 操作符以确保精确比较,同时在必要时使用 trim() 方法清理字符串。 相关搜索:js equalequal jsjs object equal如何使用Sequelize查询WHERE "NOT NULL“和"NOT EQUAL TO [STRING]”?equalhtml中equal什么是OR EQUALequal比较对象js if stringjs stringstring jstf....
可以使用String作为toString()更可靠的代替方法,因为它在用于null和undefined时仍然有效。例如: js constnullVar=null;nullVar.toString();// TypeError: nullVar is nullString(nullVar);// "null"constundefinedVar=undefined;undefinedVar.toString();// TypeError: undefinedVar is undefinedString(undefinedVar);/...
