checkbox

问题 I'm making an app that has 39 checkboxes in it. I want it to calculate the percentage of checkboxes that are currently clicked. This is java code of the app: public class Bifrost extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_bifrost); //SPREMENLJIVKE final CheckBox cb1 = (CheckBox) findViewById(R.id.checkBox1); cb1.setChecked(getFromSP("cb1")); cb1.setOnCheckedChangeListener(new

问题 How would you go about styling or refactoring this list, so that the clickable areas of the checkboxes do not interfere with each other? Is there a grouping container I am not aware of? <div layout vertical> <div layout horizontal> <paper-checkbox></paper-checkbox> <paper-item label="item 1"></paper-item> </div> <div layout horizontal> <paper-checkbox></paper-checkbox> <paper-item label="item 2"></paper-item> </div> <div layout horizontal> <paper-checkbox></paper-checkbox> <paper-item label=

问题 I'm trying to implement a simple 'show password' toggle check box so that whilst the mouse is held down, the plain text password is shown, and once it's let go it reverts back to a password field. I've got the toggle of the input field working, however I'm using a check box to show the toggle state as well, and I can check the box on mousedown however my attempt at then unchecking the box is not quite working. Here's what I've got so far; DEMO var pwi = $('#new_pass'); $('.pw_show').on(

问题 I have a ListView containing several GridViewColumns. Several of the columns are checkboxes. Each column header consists of a checkbox as well, with the intention of checking/unchecking all the checkboxes in that column. Each row's checkboxes are bound to properties in my view model. I've seen several postings where the scenario is a single column of checkboxes, but none of those solutions will work for me, as I have 4 columns of checkboxes. I also need to persist the state of the selections

问题 I am hoping another set of eyes can help me find where my code is wrong. I can compile and run the program, but all I get is a white screen. It's supposed to show the checkboxes and change the background to whichever color is chosen. Any help is appreciated! import javax.swing.JOptionPane; import java.awt.*; import java.awt.event.*; public class Chapter5Debug extends Frame implements ItemListener { static Chapter5Debug f = new Chapter5Debug(); CheckboxGroup options = new CheckboxGroup();

问题 I'm working with Ember.JS on the front-end and need to be able to create x number of input checkboxes depending on my model. Basically I want to do something like: {{#each model}} {{input type="checkbox"}} {{/each}} While that works perfectly fine, I'm not sure how I can retrieve the values of x checkboxes from the controller upon submission. If it were just one, I might say: {{input type="checkbox" checked=boxIsChecked}} But I'm not sure how I can enumerate these inputs so that I might say:

问题 <input type=checkbox [(ngModel)]="myCheckBox" (ngChanged)="!myCheckBox"> for example, if I want the code above to pass the "checked" value, which is "true or false" to other components, so its contents can react based on "myCheckBox" true | false, and they are not in a parent child relationship, is there any way I can do that? Please help, really apprecipate it!!!! 回答1: You can implement it by different methods. For example: with EventEmitter or rxjs( Subject, BehaviourSubject); In my example

问题 I am using checkboxes in a sheet (and their functionality in themselves are exactly what I need). The problems I am having is that the users who are able to edit the sheet, sometime (by mistake) delete the checkbox instead of simply checking/un-checking the checkbox. Hence, I want the users to use the checkboxes, but not be able to delete them. Is this possible somehow? FYI: it is not possible to use Google Forms in the case. 回答1: Here you have an example on how to achive it using onOpen
