Question

I want to know if its possible writing some code which will delete an initial value from a form when the user clicks on the corresponding form (described in the following example)?

class example(forms.Form):
    name = forms.CharField()
    email = forms.EmailField()
    descr = forms.CharField(initial='Please insert a relevant description ...')

I dont want to use the help_text attribute.

PS: For a better understanding I could make an analogy with java onclick event

Answer 1

One way is to use HTML5’s placeholder attribute directly from Django:

descr = forms.CharField(widget=forms.TextInput(attrs={
    'placeholder': 'Please insert a relevant description ...'}))

The unique constraint is that it is not yet supported by Internet Explorer.
