问题 Can anyone please suggest some links for using UITextField in cocos2d. I want to press on label, then the UITextField should get selected and I need to edit on that UITextField . 回答1: I'm doing this in a current project to allow for entering the number of the level to start playing at, so that's why my variables and methods are named the way they are; you should probably adjust these to make sense for you. In your app controller, define this as an instance variable: UITextField

Clear prompt text in JavaFX TextField only when user starts typing

由 做~自己de王妃 提交于 2019-11-26 19:54:40
问题 The default behaviour is that the prompt text in the field is erased as the field is being focused. That is when the marker is in the field. Is it possible to configure the textfield so the prompt text is only erased when the user have started typing? Otherwise I need to add a label beside/over each textfield for description of the value in it. 回答1: Solution This example will allow TextFields in JavaFX whose prompt behaviour is to show the prompt when the field is empty, even if the field has

Disable HTML escaping in Django's TextField

由 不问归期 提交于 2019-11-26 19:46:39
问题 How can I turn off Django's automatic HTML escaping, when I write into model's TextField? 回答1: Just use django's safe filter. In your template you would do something like this: {{ instance.my_text_field|safe }} 回答2: One way to do it is to put a function in your model which returns the data marked as safe: from django.utils.safestring import mark_safe class MyModel(models.Model): my_textfield = models.TextField() def display_my_safefield(self): return mark_safe(self.my_textfield) Then in the

javascript to find leap year

由 假如想象 提交于 2019-11-26 18:49:52
How can I get the code below to work when I have a month of february? Currently it is getting to the day and then stopping before getting to the if to determine whether it is a leap year. if (month == 2) { if (day == 29) { if (year % 4 != 0 || year % 100 == 0 && year % 400 != 0) { field.focus(); field.value = month +'/' + ''; } } else if (day > 28) { field.focus(); field.value = month +'/' + ''; } } It's safer to use Date objects for datetime stuff, e.g. isLeap = new Date(year, 1, 29).getMonth() == 1 Since people keep asking about how exactly this works, it has to do with how JS calculates the
