我想知道我是否有一个声明为：
的函数function foo(){
var x = 10;
}
如何在javascript中使用某些内容：
var foo1 = new foo();// In javascript to create an object type of a function
var xOfFoo = foo1.x;
创建函数的对象类型，并在typescript中访问它的属性？
答案 0 :(得分：0)
您可以在TypeScript中执行此操作。在这种情况下，class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, *args, **kwargs):
QMainWindow.__init__(self, *args, **kwargs)
self.setupUi(self)
self.setUpMainUiFunction()
def setUpMainUiFunction(self):
self.actionOpen.triggered.connect(self.OpenDialog)
self.Button_LoadPhoto.clicked.connect(self.OpenDialog)
open = QAction(QIcon("icons/open.bmp"), "open", self)
save = QAction(QIcon("icons/save.bmp"), "save", self)
NormalCursor = QAction(QIcon("icons/cursor-normal.png"), "NormalCursor", self)
CrosshairCursor = QAction(QIcon("icons/crosshair.png"), "CrosshairCursor", self)
self.TopToolBar.addAction(open)
self.TopToolBar.addAction(save)
self.LeftToolBar.addAction(NormalCursor)
self.LeftToolBar.addAction(CrosshairCursor)
# self.TopToolBar.actionTriggered[QAction].connect(self.toolbtnpressed)
def OpenDialog(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
PicturePath = QStandardPaths.standardLocations(QStandardPaths.PicturesLocation)[0]
filenames, _ = QFileDialog.getOpenFileNames(self, "Open File", PicturePath, "JPEG File (*.png)", options=options)
for filename in filenames:
pixmap = QPixmap(filename)
self.showPicture(pixmap)
self.statusbar.showMessage("Successfully Loaded: {}".format(filename))
def showPicture(self, picture):
sub = QMdiSubWindow(self)
loadPicture = LoadPicture(picture, sub)
sub.setWidget(loadPicture)
sub.setObjectName("Load_Picture_window")
sub.setWindowTitle("New Photo")
self.mdiArea.addSubWindow(sub)
sub.show()
sub.resize(picture.size())
loadPicture.log.MousePixmapSignal.connect(self.updatePixel)
def updatePixel(self, point, color):
self.UserInput_PixelValue_X.setText("{}".format(point.x()))
self.UserInput_PixelValue_Y.setText("{}".format(point.y()))
self.UserInput_PixelValue_R.setText("{}".format(color.red()))
self.UserInput_PixelValue_G.setText("{}".format(color.green()))
self.UserInput_PixelValue_B.setText("{}".format(color.blue()))
将引用函数的范围，因为函数声明不在类中。
