我一直致力于视觉力搜索页面并遇到了问题。我有一个文本输入部分来搜索记录的名称。但是，每次输入任何字母时它都会更新。我希望它只在用户停止输入后进行搜索。我发现this post关于这个问题。但是，由于我对编码很新（特别是使用js），我似乎无法弄清楚如何使用其他帖子中的js代码触发我的操作。谢谢你的帮助！
这是我的VF页面代码：

var delay = (function(){
var timer = 0;
return function(callback, ms){

timer = setTimeout(callback, ms);
};
})();
$('#name').keyup(function() {
delay(function (){

});

$('#name').keyup(function() {
delay(function (){
// Whatever you want to trigger paste it here.
}, 1000 );
});
并且此1000决定用户停止输入后要触发的毫秒数
