# 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'});
