Question

我是从课堂上写的，然后尝试添加占位符

__declspec(noinline) int testArgsAsm(int* x, char* cp, int a, int b, int c, int d, int e)
{
    std::cout << *x << *cp;
    int sum = a + b + c + d + e;
    if (sum == 0)
        std::cout << "0";
    else
        std::cout << "Non 0";
    return sum;

}
int main(int argc, const char** args)
{
    int a, b, c, d, e;
    int* ip = new int; *ip = 0x101;
    char* cp = new char; *cp = ('g');
    std::cin >> a >> b >> c >> d >> e;
    testArgsAsm(ip, cp, a,b,c,d,e);
    return 0;
}

像这样并获得错误列表

class ContactUs(forms.Form):
    your_email = forms.EmailField(help_text='Enter a valid email.')
    subject = forms.CharField(max_length=100, help_text='Enter your subject.')
    message = forms.CharField(widget=forms.Textarea(attrs={'placeholder':'test'}), help_text='Enter your message.')
    cc = forms.BooleanField(required=False)

Answer 1

即使使用getData(); // Call *sync* function console.log('my_data2', my_data);，您也可以添加小部件。要添加更多EmailField，您可以使用小部件

来执行此操作

attribute

Answer 2

你可以使用这样的东西：

q = forms.CharField(label='search', 
                widget=forms.TextInput(attrs={'placeholder': 'Search'}))
