是否从jQuery变量中删除并替换字符并设置为新变量？

var originalString = "Hello World!";
var newString = originalString.replace("o", ""); // 删除字符"o"
console.log(newString); // 输出: "Hell Wrld!"

var originalString = "Hello World!";
var newString = originalString.replace("o", "a"); // 将字符"o"替换为"a"
console.log(newString); // 输出: "Hella Warld!"

var originalString = "Hello World!";
var newString = originalString.replace("o", ""); // 删除字符"o"并设置为新变量
console.log(newString); // 输出: "Hell Wrld!"
