Getting Started

jqxComplexInput represents an input widget for entering complex numbers and getting their real and imaginary parts. The complex input also supports on-keydown and on-change number validation.

Every UI widget from jQWidgets toolkit needs its JavaScript files to be included in order to work properly.

The first step is to create html page and add links to the javascript files and css dependencies to your project. The jqxComplexInput widget requires the following files:

The next step is to create an Input element within the body of the html document:
If you wish to enable spin buttons, you would have to create the following HTML structure instead:
The last step is to initialize the widget by adding the following script to the html document:
To call a function(method), you need to pass the method name and parameters (if any) in the jqxComplexInput's constructor:

$("#jqxComplexInput").jqxComplexInput("refresh");
 

To get the complex input's value, you need to do the following:

var value = $("#jqxComplexInput").val();
 

To set a property (option), you need to pass the property name and value(s) in the jqxComplexInput's constructor:

$("#jqxComplexInput").jqxComplexInput({ width: 150 });
 

To get a property (option), you need to pass the property name to the jqxComplexInput's constructor:

var width = $("#jqxComplexInput").jqxComplexInput("width");
 

To bind to an event of a UI widget, you can use basic jQuery syntax. Let’s suppose that you want to know when the input value is changed:

// bind to 'change' event.
$('#jqxComplexInput').on('change', function (event) {
 
});
