mask

问题 I need a WPF Textbox that displays a phone number as "(555) 555-5555" but has a value of "5555555555". All of the examples I'm seeing have the ability to mask the control on the UI but that affects the bound property of my view model so that the property value has the extraneous ()- characters. 回答1: How about an IValueConverter? 回答2: I am thinking that you will probably have to roll-your-own. It shouldn't be too difficult, subclass and override to obtain the results you are looking for. 来源：

I've tried and failed with a bunch of other approaches but just pasting the one that I thought would most likely work (I'm super new to coding) %matplotlib inline

问题 I have an input field and I want to limit it to alphanumerical (A-Z, a-z, 0-9) characters only, with a MINIMUM field length of 5, and a maximum length of up to 15 characters total. Does anyone know how I can do this using jQuery? I'm trying to use the jQuery input mask by digitalBush - http://digitalbush.com/projects/masked-input-plugin/ The problem is that UNLESS I enter 15 characters, the field goes blank. If I enter "012345678912345" (15 characters) in the input field then the value is

问题 Hi folks I'd appreciate some .htaccess advice. I have two wordpress installations.

问题 Q: I wanna to mask my textbox , so if the user enter the number one for example it formatted as 0000001 how to do this ,any number in 7 digits. 回答1: I think you are going to need something like this padding function.

Set its properties such as
