Top 10 Helpers You Should Know About


This method is used mainly to instantiate Webix component of any complexity level, whether it is a control or a complete application layout.

It converts a JSON structure passed into it as a parameter to client-side layout objects - this is what Webix is used for:)

webix.ui({ view:"", ... });

Normally, you need one webix.ui() constructor for the whole application while any window or popup needs an extra one as windows lie above page layout.

webix.ui({ view:"window", ... }).show();

More opportunities of using this method are described in the chapter Rebuilding Application Layout.


This method is a cross-browser alternative to the onDocumentReady event and can be used instead of onload() method. Code, which was put inside of it, will be called just after the complete page has parsed, protecting you from potential errors. The thing is optional but we recommend to use it.

It can be used multiple times.


API reference


An easy way to bind a function to an object (inside bound function, this will point to an object instance).

var t = webix.bind(function(){
}, "master");
t(); //will alert "master"


This method allows you to make a full (independent) copy of an object:

var new_obj = webix.copy(source_obj)// full copy

API reference


Adds methods and properties of the source object to the target object:

var target_obj = new webix.ui.toolbar(config);
webix.extend(target_obj, webix.Movable);

Also, it can be used as one more method to get an object copy. In such a case, you must specify an empty object as the second parameter.

var new_obj = webix.extend({},source_obj) //object based copy

API reference


This helper allows executing code string at runtime.

webix.exec(" var t = 2; ");

It has an advantage over eval: variables defined in code will be defined in the global scope, the same as in case of a normal js code.

API reference


Delays routine. If you need to delay some code from executing at runtime you are at the right place. webix.delay waits for the specified number of milliseconds and then executes the specified code.

webix.delay(webix.animate, webix,[node,animation],10)

API reference


A tool for getting a unique id (id is unique per session, not globally unique).

var name = webix.uid();

API reference


webix.event is used to attach event handlers and webix.eventRemove - to remove them.

var display_handler = webix.event(document.body,'click',function(e){})

API reference


With the help of this method you can get the position of any HTML element.

var offset = webix.html.offset(

API reference


Two methods implementing CSS manipulations. webix.html.addCss allows adding a CSS class to an element, webix.html.removeCss - removes some defined CSS class.

webix.html.addCss(this._headbutton, "collapsed");
webix.html.removeCss(this._headbutton, "collapsed");
