Element Checkbox

JXG.GeometryElement,JXG.CoordsElement
   ↳ JXG.Text
      ↳ Text
            ↳ Checkbox

This element is used to provide a constructor for special texts containing a form checkbox element. For this element, the attribute "display" has to have the value 'html' (which is the default).

Setting a CSS class: The attribute cssClass affects the HTML div element that contains the checkbox element. To change the CSS properties of the HTML checkbox element a selector of the form .mycheck > checkbox { ... } has to be used. See the analog example for buttons: Button.

Access the checkbox element with JavaScript: The underlying HTML checkbox element can be accessed through the sub-object 'rendNodeCheck', e.g. to add event listeners.

Defined in: checkbox.js.
Extends Text.

Element Detail
Checkbox
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "checkbox".

Possible parent array combinations are:
{number|function} x
{number|function} y
{String|function} label

Parent elements for checkbox elements.

x and y are the coordinates of the lower left corner of the text box. The position of the text is fixed, x and y are numbers. The position is variable if x or y are functions.

The label of the input element may be given as string or function.

The value of the checkbox can be controlled with the attribute checked

The HTML node can be accessed with element.rendNodeCheckbox



Examples:
  // Create a checkbox element at position [0,3].
  var checkbox = board.create('checkbox', [0, 3, 'Change Y'], {});
  var p = board.create('point', [
      function(){ return 0.5;}, // X-coordinate
      function() {
          y = 0.5;
          if (checkbox.Value()) {
              y += 0.5;
          }
          return y;
      }]);

The checkbox can be supplied with custom-made events by using the property rendNodeCheckbox.
var checkbox = board.create('checkbox', [0, 4, 'Click me']),
    p = board.create('point', [1, 1]);

JXG.addEvent(checkbox.rendNodeCheckbox, 'change', function() {
    if (this.Value()) {
        p.moveTo([4, 1]);
    } else {
        p.moveTo([1, 1]);
    }
}, checkbox);

				
				
    var i1 = board.create('input', [1, 5, 'sin(x)', 'f(x)='], {cssStyle: 'width:4em', maxlength: 2});
        var c1 = board.create('checkbox', [1, 3, 'label 1'], {});
        var b1 = board.create('button', [1, 1, 'Change texts', function () {
                i1.setText('g(x)=');
                i1.set('cos(x)');
                c1.setText('label 2');
                b1.setText('Texts are changed');
            }],
            {cssStyle: 'width:200px'});
