JavaScript - Using “checked/unchecked checkbox” as “IF ELSE condition statement”

由 别说谁变了你拦得住时间么 提交于 2019-12-23 19:17:14
问题 Now I want to use "check/unchecked checkbox" as "IF condition statement". Example: I want to make a chord analyzer based on the note(s) you hit. When you check a note (or some notes) on checkbox, then press the button under those checkboxes, the paragraph element should tell you about what chord you hit. But there's error on my writing at if ("error") statement. How to fix it? Here's my code: <!doctype html> <html> <head> <script> function fungsi() { var c = document.getElementById("C")

Ruby on Rails Forms: how to create a CheckBox Table (or List)

由 ∥☆過路亽．° 提交于 2019-12-23 19:17:04
问题 What's the best way to create a related set of checkboxes in Ruby on Rails? In the ToscaWidgets library used by Turbogears you can do the following: twf.CheckBoxTable('arbitrary_numbers', num_cols=5, options=['1','2','3','4','5','6','7','8','9','10']), This generates 10 labeled checkboxes in two rows of 5 checkboxes. I'm trying to duplicate this in Rails without just creating 10 separate checkbox controls. No big deal, just hoping for a clean way to do this. 回答1: Something like this: <% 10

Odd behavior rendering dynamically type of input type checkbox Angular 2+

由 跟風遠走 提交于 2019-12-23 19:14:57
问题 Need: Create an input with the type attribute dynamic. Something like this: <input id="{{ field.id }}" formControlName="{{ field.code }}" type="{{ field.type }}" /> Use the above input with "checkbox" dynamic value inside a FormGroup (reactive forms). Problem: The problem comes when i set the type attribute dynamically and what it causes is creating the checkbox in the DOM with an attribute value="false" when i initialize the FormControl with false . Therefore the FormGroup never gets updated

问题 I'm an asp.net mvc newbie. I have a checkbox in my form @Html.CheckBox("Don't show my number", Model.IsPhonePublic) But whether I check the box or not the Model.IsPhonePublic is always false while submitting the form.
