html结构

</form>

js：

//当在搜索框输入内容时，根据关键字匹配，显示弹出层

functionsearchSuggest(obj){

varsearchKey=$(obj).val();

varreg =newRegExp(searchKey,"i");//忽略大小写匹配搜索框中输入的内容

$.ajax({

type:"get",

url:"data/keyword.json",

dataType:"json",

success:function(data){

vararr=[];

for(vari=0,len=data.length;i<len;i++){

if(searchKey!=""&& (data[i].initial.search(reg)!=-1 || data[i].keyword.search(reg)!=-1)) {

arr.push("<li onclick='changeSearchKey(this);'>"+data[i].keyword+"</li>");

}

$(".keywords_list").html(arr).show();

}

});

}

//单击匹配列表中的关键字选项时，将该关键字显示在搜索框中

functionchangeSearchKey(obj){

varvalue=$(obj).text();

$("#searchKey").val(value);

$('.keywords_list').hide();

}
