Question

我正在使用TableSorter对表进行排序，因为我正试图替换数据表（因为它难以处理大型数据集）。我正在使用以下Javascript：

$('#tableID').tablesorter({
    widgets: ["saveSort"] ,
    dateFormat : "dd/mm/yyyy" // set the default date format
});

它不起作用。如果我对日期列之一进行排序，则其排序如下

23/08/2019
2019/04/30
11/08/2019

这甚至没有数字排序，所以我很困惑。我也尝试过使用dateformat：'uk'，但没有运气

有人有什么想法吗？

Answer 1

我实际上只是发现日期格式应该是“ ddmmyyyy”而不是“ dd / mm / yyyy”

我一定只是需要橡皮鸭，谢谢

我的猜测是，您应该在JS中键入不带斜杠的格式，但在HTML文件中使用斜杠保留格式。就您而言：

public void dropFile(WebElement target, int offsetX, int offsetY) {
        String workingDir = System.getProperty("user.dir");
        String filepath = workingDir + "\\Testdata.txt";
    //    JavascriptExecutor jse = (JavascriptExecutor) driver;

        String JS_DROP_FILE = "var args = arguments,"+
                "element = args[0],"+
                "offsetX = args[1],"+
                "offsetY = args[2],"+
                "doc = element.ownerDocument || document;"+

              "for (var i = 0; ;) {"+
                "var box = element.getBoundingClientRect(),"+
                  "clientX = box.left + (offsetX || (box.width / 2)),"+
                  "clientY = box.top + (offsetY || (box.height / 2)),"+
                  "target = doc.elementFromPoint(clientX, clientY);"+

                "if (target && element.contains(target))"+
                    "break;"+

                "if (++i > 1) {"+
                  "var ex = new Error('Element not interactable');"+
                  "ex.code = 15;"+
                  "throw ex;"+
                "}"+

                "element.scrollIntoView({behavior: 'instant', block: 'center', inline: 'center'});"+
              "}"+

              "var input = doc.createElement('INPUT');"+
              "input.setAttribute('type', 'file');"+

                "input.parentElement.removeChild(input);"+
                "ev.stopPropagation();"+

                "var dataTransfer = {"+
                  "constructor   : DataTransfer,"+
