checkbox

问题 I'm using Node+Express+Jade to render some webpages. On a form there are 2 checkboxes. When the form is submitted through POST, if the checkbox is checked, I get req.body.checkbox1 -> 'on' , if isn't checked, I get req.body.checkbox1 -> undefined Is possible to get checkbox value as true or false ? Here's my server side test code var bodyParser = require('body-parser'); var express = require('express'); var app = express(); app.use(bodyParser.urlencoded({extended: true})); app.use(express

问题 I have loaded 6 kml layers via url to my website to be toggled off/on by checkboxes. I have recently notice though, that it will only allow me to show 4 kml's at a given time. When I select more than 4 the 5th and 6th does not show. It does not matter what ones I choose, it seems to limit me to only showing 4. Can someone direct me on what may be causing this or should I be coding this some other way? The kml's by themselves do work and are under 800kb. Is just seems very weird that I can

问题 I want to run a macro when I click a checkbox in Word 2010 . Note that I neither want the "Legacy Forms" checkbox nor the "ActiveX" ones! They do only work in some "protected document mode" and look ugly, but I want the new ones which can be selected and unselected just when you write the document, and which look much nicer to me. I know, with the legacy forms, you can directly insert a Macro when entering the form element and one for leaving it, and you can catch the event in VBA like Sub

问题 I'm trying to dynamically add textareas to a div within a form depending on which checkboxes are checked. The textareas are added as <li> elements within an <ol> parent element so its just a list of textareas. My JQuery adds the textareas whenever the "CaseGrounds" checkboxes are checked, but I'm not sure how to remove the appropriate textareas if the relevant checkbox is unchecked. I thought I would be clever and empty the <ol> before adding textareas, but this causes the problem of it only

问题 Introduction Context: I am working on one of my first own apps, a sort of note-taking app. The basic framework is simple: I have a UITableView with cells in them with a few design elements and a large UITextView which the user can write their notes into. Issue: I would like to implement the checkbox feature, similarly to what Apple has in their app "Notes". I want it to be a "part" of the text, so its erasable by hitting the erase on the keyboard. I have checked posts on SO about inserting a

问题 I have tried to make a xml selector with the following: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/shuffleon" android:state_checked="true" /> <item android:drawable="@drawable/shuffleoff" android:state_selected="false" /> </selector> and when I try to set the backgroundDrawable to the checkBox the checkbox doesn't replace the CheckBox style too: shuffle.setBackground(android.support.v4.content

问题 I am using QTableView's checkbox flag of Qt::ItemIsUserCheckable to display a checkbox in a table cell. After reading some things on alignment in an attempt to center the checkbox within the cell, I am returning the Qt::AlignCenter as the TextAlignmentRole from the models data() function. QVariant ExampleModel::data(const QModelIndex &index, int role) const { if(!index.isValid()) return QVariant(); if (role == Qt::TextAlignmentRole) return Qt::AlignCenter | Qt::AlignVCenter; } This however is

问题 I researched a lot, and I found this JSFiddle looks like what I need, but, when I click the button, the page background is changing. I want the button's color to be changed when clicked, instead. div{ width: 100%; height: 100%; background: #5CB85C; position: absolute; top: 0; left: 0; z-index:1; } label.btn { position: absolute; top:10px; left: 10px; z-index:2; -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user
