autocomplete

$("#department").autocomplete('/oms/orgAjax/getSimilarNames', {
width: 162,
minChars: 2,
        dataType: 'json',
        highlight: false,
        scroll: true,
        scrollHeight: 300,
        parse: function(data) {
var array = new Array();
for(var i = 0 ; i < data.orgNames.length; i++){
        array[array.length] = {data: data.orgNames[i], value: data.orgNames[i], result: data.orgNames[i]};
}
return array;
        },
        formatItem: function(row){
        return row;
        },
        onReSelect: function(options) {
        alert("reselect" + options);
        return options;
        }
}).result(function(event, item) {
alert("result" + item);
});;


自定义事件onReSelect，在源码中添加如下代码：
function onChange(crap, skipPrevCheck) {
if (options.onReSelect) {
var op = options.onReSelect(options);
if (op) {
$.extend(options, op);
}
}

if( lastKeyPressCode == KEY.DEL ) {
select.hide();
return;
}

var currentValue = $input.val();

if ( !skipPrevCheck && currentValue == previousValue )
return;

previousValue = currentValue;

currentValue = lastWord(currentValue);
if ( currentValue.length >= options.minChars) {
$input.addClass(options.loadingClass);
if (!options.matchCase)
currentValue = currentValue.toLowerCase();
request(currentValue, receiveData, hideResultsNow);
} else {
stopLoading();
select.hide();
}
};
