有没有办法'白名单' - 或者防止 - 在try catch块中抛出特定的错误?

例如,假设我有一个例外,我知道并且不想记录。但是,我想捕获try / catch块中弹出的任何其他错误。


这是我能想到的最好的:

try {
...
} catch(exception) {

    //Loop through a predefined list of known errors that we want to ignore.
    for (var i in whitelistOfErrors) {

        //if our exception MATCHES an error that we want to ignore,
        //don't throw it
        if (exception == whitelistOfErrors[i])
            break;

        //if our exception DOESN'T MATCH an error that we want to ignore,
        //throw it
        if (i = whitelistOfErrors.length)
            throw exception;
    }
}

(或者用一种为你搜索数组的方法替换逻辑,如果存在的话)
