javascript - 从 JavaScript 中的日期中删除 GMT-#### 文本？

Question

我想从结果中删除“GMT-####”文本。日期/时间结果将根据用户输入的搜索条件而有所不同。

    for (var j = 0; j < resultCountGLM; j++) {

            var featureAttributes2 = results[1].features[j].attributes;
            //console.log(featureAttributes2)

            if (attr = "DATE_UTC") {
                attr1 = "Detected during the 1-hour period beginning"
                var dateGM = new Date(featureAttributes2[attr]);
                resultItems.push("<p class='reportTextResults_font'><b>" + attr1 + ":</b>  " + dateGM + "</p>");
            }
        }
        resultItems.push("<br>");

示例输出:

    Detected during the 1-hour period beginning: Thu Jan 02 2020 14:00:00 GMT-0600 (Central Standard Time)
    Detected during the 1-hour period beginning: Thu Jan 02 2020 16:00:00 GMT-0600 (Central Standard Time)

期望的输出:

    Detected during the 1-hour period beginning: Thu Jan 02 2020 14:00:00 (Central Standard Time)
    Detected during the 1-hour period beginning: Thu Jan 02 2020 16:00:00 (Central Standard Time)

Answer 1

如果你想使用普通的 javascript，你有两个选择。要么自己删除它，要么查看 .toXXX 函数之一。示例:

new Date().toLocaleString()
//"1/14/2020, 1:05:58 PM"

如果您需要它完全如此或可能更精细，有很多库可以帮助格式化日期。
