knockoutjs -- all built-in buildings

所有可用的binding值

• 文字和显示：visible, text, html, css, style, attr
• 流程控制：foreach, if, ifnot, with
• form字段:click, event, submit, enable, disable, value, hasFocus, checked, options, selectedOptions, uniqueName
• 模版：template
• 自定义blinding

event:
Passing a “current item” as a parameter to your handler function
Accessing the event object, or passing more parameters
Allowing the default action
Preventing the event from bubbling

data-bind="event: { mouseover: enableDetails, mouseout: disableDetails }
data-bind="event: { mouseover: function(data, event) { myFunction(data, event, 'param1', 'param2')

如果在流程控制的Binding，如foreach、with中嵌套了其他binding，那么通常需要使用前缀访问。
$parent — is the data item outside the current foreach block
$parents -- 多层流程控制嵌套时
$parents[0]
$root
