// example:
// step1 :
// create autocomplete container, return object and bind event to the object, and
///create a new jsAuto instance:
// <div id="divautocomplete"></div>
// var autocomplete = new jsAuto("autocomplete","divautocomplete")
// handle event:
// autocomplete.handleEvent(value, returnObjectID)
// <input id="rautocomplete" onkeyup="autocomplete.handleEvent(this.value,"ratocomplete",event)>
// step2 :
// add autocompete item:
// autocomplete.item(string)
// string must be a string var, you can split the string by ","
// autocomplete.item("blueDestiny,never-online,csdn,blueidea")
