theme String ''

Sets the widget's theme.

jQWidgets uses a pair of css files - jqx.base.css and jqx.[theme name].css. The base stylesheet creates the styles related to the widget's layout like margin, padding, border-width, position. The second css file applies the widget's colors and backgrounds. The jqx.base.css should be included before the second CSS file. In order to set a theme, you need to do the following:
  • Include the theme's CSS file after jqx.base.css.
    The following code example adds the 'energyblue' theme.
    
                                    
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.energyblue.css" type="text/css" /> 
  • Set the widget's theme property to 'energyblue' when you initialize it.
Try it: theme is set to 'energyblue'
value String ''

Sets or gets the value of the jqxComplexInput widget.

Code example

Set the value property.

$("#jqxComplexInput").jqxComplexInput({ value: "190 - 17i" });

Get the value property.

var value = $('#jqxComplexInput').jqxComplexInput('value');
Try it: value is set to "190 - 17i"
width Number/String null

Sets or gets the jqxComplexInput's width.

Code examples

Set the width property.

$('#jqxComplexInput').jqxComplexInput({ width: 200 });

Get the width property.

var width = $('#jqxComplexInput').jqxComplexInput('width');
Try it: width is set to 200

Events

change Event

This event is triggered when the value is changed.

Code examples

Bind to the change event by type: jqxComplexInput.

$("#jqxComplexInput").on("change", function (event) {
    // event arguments
    var args = event.args;
    if (args) {
        // new value
        var value = args.value;
        // old value
        var oldValue = args.oldValue;
        // real part
        var realPart = args.realPart;
        // imaginary part
        var imaginaryPart = args.imaginaryPart;
        // type
        var type = args.type; // keyboard, mouse or null depending on how the value was changed.
