将Javascript Ajax响应与字符串进行比较

var str1 = "Hello";
var str2 = "World";
if (str1 == str2) {
  console.log("Strings are equal");
} else {
  console.log("Strings are not equal");
}

var str1 = "apple";
var str2 = "banana";
var result = str1.localeCompare(str2);
if (result < 0) {
  console.log("str1 comes before str2");
} else if (result > 0) {
  console.log("str1 comes after str2");
} else {
  console.log("str1 and str2 are equal");
}

var str = "Hello, World!";
var substring = "World";
if (str.indexOf(substring) !== -1) {
  console.log("Substring found");
} else {
  console.log("Substring not found");
}
