Input Validation

[liyanchang]

I'll let you determine priority - this seems pretty low to me.

Browser: Chrome, Safari, I presume all.

On quick-screener.html:

• You can put in letters in the zip and it will work: "121sdwd"
• The income field is not required. (Fun fact: If you put "0b1111111111111", it'll work)
• If you put letters in household size, you get "NaN people" on eligible.html
• Letters work in cooking field.

Browser: Safari On applicant-dob-sex.html:

• If you put in a bad month, there isn't a message.

I presume this continues for all the fields.

@liyanchang I haven't added any robust validation to the demo, but it should be there in the rails app.

I'll hope to get those all in sync at some point.
