Javascript将Array中的特定ID值提取到另一个Array

Question

我在脚本上有结果数组,如下所示:

var myurlsave = [{"url_field":"yahoo","enabled":true},{"url_field":"google","enabled":true},{"url_field":"bing","enabled":true}];

我想将它提取为如下所示:

var myurlname = ["yahoo", "google", "bing"];

我认为这对你来说很容易,但我很难做到这一点.谢谢您的帮助

Answer 1

var arr = myurlsave.map(function(a) {
    return a.url_field;
});
