bootstrap输入框下拉

使用struts2框架

1.html代码

<input type="text"  class="form-control nav-search-input" id="searchProjectName" name="searchProjectName" value='<s:property value="searchProjectName"/>'/>

2.js代码

$.getJSON("AllProjectStrArray.action?dataState="+dataState+"&date="+new Date(), function(json2){
if(json2!=null){
$("#searchProjectName").autocomplete({
source: json2,
minLength:0,
change:function( event, ui ) {
if(ui.item==null){
LoadProductNamesToAutoComplete("");
}else{
LoadProductNamesToAutoComplete(ui.item.label);
}
}
});
}
});

/*设置未选中时显示下拉列表值*/
$("#searchProjectName").on("click",function(){
$( "#searchProjectName" ).autocomplete("search","");
});

3.struts2配置

  <action name="AllProjectStrArray" class="包名称.ProjectAction"
method="allObjectStrArray">
<result type="json">
<param name="root">allProjectStringArray</param>
</result>
</action>
