Array.prototype.indexOf()
Array.prototype.indexOf()
if(result.indexOf("test") > -1)
Since this still gets up votes I'll edit in a more modern answer.
由于这仍然得到投票，我将编辑一个更现代的答案。
With es6 we can now use some more advanced array methods.
使用 es6，我们现在可以使用一些更高级的数组方法。
Array.prototype.includes()
Array.prototype.includes()
result.includes("test")which will return a true or false.
result.includes("test")这将返回真或假。
Array.prototype.some()
Array.prototype.some()
If your array contains objects instead of string you can use
如果您的数组包含对象而不是字符串，您可以使用
result.some(r => r.name === 'test')which will return true if an object in the array has the name test.
result.some(r => r.name === 'test')如果数组中的对象具有名称 test，则返回 true。

The jQuery object does not have a containsmethod. If you are expecting the returned result to be a string, you can check if your substring is contained within it:
jQuery 对象没有contains方法。如果您希望返回的结果是一个字符串，您可以检查您的子字符串是否包含在其中：
if ( result.indexOf("test") > -1 ) {
//do something
}
If your result is JSON, and you're checking for a top-level property, you can do:
如果您的结果是 JSON，并且您正在检查顶级属性，您可以执行以下操作：
if ( result.hasOwnProperty("test") ) {
//do something
}
