这样写在ff下看到报错event is not defined，哪里出错啊 ？高手帮帮忙
document.onclick=function(){
if(event.srcElement.id!="ContactName_div" && event.srcElement.id!="ContactName"){document.getElementById('ContactName_div').style.display='none';
}
}
document.onclick=function(){
if(event.srcElement.id!="ContactName_div" && event.srcElement.id!="ContactName"){document.getElementById('ContactName_div').style.display='none';
}
}

# Sortable
Sortable is a minimalist JavaScript library for reorderable drag-and-drop lists.
Demo: http://rubaxa.github.io/Sortable/
## Features
* Supports touch devices and [modern](http://caniuse.com/#search=drag) browsers (including IE9)
* Can drag from one list to another or within the same list
* CSS animation when moving items
* Supports drag handles *and selectable text* (better than voidberg's html5sortable)
* Smart auto-scrolling
* Built using native HTML5 drag and drop API
* Supports
* [Meteor](https://github.com/SortableJS/meteor-sortablejs)
* AngularJS
* [2.0+](https://github.com/SortableJS/angular-sortablejs)
* [1.*](https://github.com/SortableJS/angular-legacy-sortablejs)
* React
* [ES2015+](https://github.com/SortableJS/react-sortablejs)
* [Mixin](https://github.com/SortableJS/react-mixin-sortablejs)
* [Knockout](https://github.com/SortableJS/knockout-sortablejs)
* [Polymer](https://github.com/SortableJS/polymer-sortablejs)
* [Vue](https://github.com/SortableJS/Vue.Draggable)
* Supports any CSS library, e.g. [Bootstrap](#bs)
* Simple API
* [CDN](#cdn)
* No jQuery (but there is [support](#jq))
