Question

我需要将日期字符串“28/01/2018”（dd / mm / yyyy）转换为qml中的Date（）。

我试过这个：

The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.
The first line of each test case contains four space-separated integers N, M, X and K.
The second line contains a single string S.



for t in xrange(int(raw_input())):
    n, m, x, k = map(int, raw_input().split())
    s = raw_input()
    even = m/2
    odd = m - even
    e, o = 0, 0 
    work, worked = 0, 0
    for i in s:
        if i == 'E':
            e += 1
        else:
            o += 1
    for k in xrange(even):
        if e > 0 and e >= x:
            worked += x
            e -= x
        elif e > 0 and e < x:
            worked += e
            e -= e
    for j in xrange(odd):
        if o > 0 and o >= x:
            work += x
            o -= x
        elif o > 0 and o < x:
            work += o
            o -= o
    if work + worked == n:
        print 'yes'
    else:
        print 'no'

还看到了这个： conversione from string ，但我的问题是我继续收到“NaN”或“无效日期”，如何从qml中的字符串中获取Date（）？

由于

Answer 1

传递给var dateBoard = "01/31/2018" var someDateTest = Date.fromLocaleString(Qt.locale(), dateBoard, "dd/MM/yyyy") var test = someDateTest.getDate() //nan的字符串必须是预期的格式。试试这段代码：

dateBoard

由于fromLocaleString中的字符串代表 MM / dd / yyyy 格式的日期，getDate将返回无效日期和nan {{1}因此。

如果dateBoard为空字符串，为空或未定义，则同样适用。

将日期字符串转换为qml中的date（）
