I actually working on a website-project. Behind my website, I′ve got a database with recipes.
我实际上在做一个网站项目。在我的网站后面，我有一个包含食谱的数据库。
Now to my problem: on the top of my page, I′ve got a textarea, with which it should be possible to search recipes in the database. My database gives back the following JSON-Object:
现在我的问题是：在我的页面顶部，我有一个文本区域，应该可以在数据库中搜索食谱。我的数据库返回以下 JSON 对象：
{"Data":{"Recipes":{"Recipe_7":{"ID":"7","TITLE":"Wurstel"},"Recipe_43":{"ID":"43","TITLE":"Wurstel2"}}},"Message":null,"Code":200}
I′ve already parsed it that I only have the title:
我已经解析了它，我只有标题：
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var obj = jQuery.parseJSON(xmlhttp.responseText);
var str="";
$.each(obj.Data.Recipes, function(){
str += this.ID + "<br/>";
str += this.TITLE + "<br/><br/>";
});
document.getElementById("txtHint").innerHTML = str;
document.getElementById("txtHint").style.border="1px solid #A5ACB2";
}
What I don′t know now is, how to write the str string into a dropdown beneath the search-textarea. What type of element is this?
我现在不知道的是，如何将 str 字符串写入搜索文本区域下方的下拉列表中。这是什么类型的元素？
