问题描述
I have gone through many ques here on stackoverflow with regard to my query here but could not apply them to my problem. 
关于我的查询，我在stackoverflow上遇到了很多问题，但是无法将它们应用到我的问题中。
Hence I am giving here my files that I have been using. 因此，我在这里给出了我一直在使用的文件。
I am successfully able to use autocomplete with a static textbox. 我成功地将自动完成功能与静态文本框一起使用。 I get the data from the database. 我从数据库中获取数据。 But however I am not able to figure out how to do it for dynamically generated textboxes. 但是，我无法弄清楚如何为动态生成的文本框做到这一点。 I want autocomplete feature to be implemented for dynamically generated textboxes with data from databases 我希望为包含数据库数据的动态生成的文本框实现自动完成功能

Just call your .autocomplete() function on your newly added inputs AFTER they have been added to the DOM 只需在新添加的输入添加到DOM后调用.autocomplete()函数
function addForm() {
$("#forms").append("<form><input type ='text' name='winner' id='winner'><br/></form>");
$("#winner").autocomplete("autocomplete.php", {
selectFirst: true
});
}

I suggest you put the init code ($('#id').autocomplete) for autocompletion on the js code part that update your page dynamically. 我建议你把init代码（$（'＃id'）。autocomplete）用于动态更新页面的js代码部分的自动完成。 I guess you're using ajax, so you should have someting like that 我猜你正在使用ajax，所以你应该有这样的东西
$.ajax({
// your ajax options here
}).done(
// here you update your html page
// and then set the autocomplete on the new element
)
