Checkbox 'check' event

The following is in the initComponent of an extending class:

this.checkBoxArray[0].on('check(this.checkBoxArray[0]', false), this.enableAllCheckboxes, this);

It does not execute this.enableAllCheckboxes() after unclicking the c开发者_Python百科heckbox.

Your code should be...

ExtJS 3.x:

this.checkBoxArray[0].on('check', this.enableAllCheckboxes, this);

ExtJS 4.x:

this.checkBoxArray[0].on('change', this.enableAllCheckboxes, this);

Add () to the function in the second argument
