使用bootstrap typeahead插件实现输入框自动补全之问

<script type="text/javascript">
jQuery(function($) {
//typeahead.js
//example taken from plugin's page at: https://twitter.github.io/typeahead.js/examples/
var substringMatcher = function() {//substringMatcher()方法
return function findMatches(query, process) {//query 是配备的关键字，processj是返回的值
var matches, substringRegex;
var params = {"token": getStorage("token"), "flag":0,"name":query};
var parameter_str="";
for(var key in params){ 
parameter_str+="&"+key+"="+params[key];
} 
var fullurl=getOption("gykj_host")+"institution/list?"+getOption("gykj_callbackparam")+"="+getOption("gykj_callbackfunc")+parameter_str;
$("#submenu_info").html(fullurl);
$.ajax({
url:fullurl,
type:'get',
dataType:"jsonp",
jsonp:getOption("gykj_callbackparam"),
jsonpCallback:getOption("gykj_callbackfunc"),
async:false,
error:function(){
alert("列表"+getOption("connectionErrorMessage"));
},
suess:function(data){
//$("#submenu_info").html(fullurl);
if(data.code==0){
var arr,substringRegex;
arr=[];
substrRegex = new RegExp(query);//这必须有，要不还是显示为underfined
for(var item in data.data){
var str= data.data[item].name;
if (substrRegex.test(str)) {
// the typeahead jQuery plugin expects suggestions to a
// JavaScript object, refer to typeahead docs for more info
arr.push({ value:str});
}
}
process(arr);
}
}
})
}
}
$('input.typeahead').typeahead({
hint: true,
highlight: true,
minLength: 1
}, {
name: 'states',
displayKey: 'value',
source: substringMatcher()//当前版本source属性中不能直接调用ajax方法获取数据源，通过substringMatcher()方法
});
});
