文件 auto.html 有一个由 6 行组成的表。当用户在文本框中输入值并单击添加按钮时，表格中的行数会增加。我正在使用所有文本框的类属性来根据类选择器执行自动完成。现在我也需要为动态创建的文本框实现自动完成，我什至尝试了 id 选择器（在评论中给出）。我在动态添加的文本框中看到了几个与自动完成问题相关的问题，但没有一个能充分解决我的问题。我在下面包含了我的代码。

auto.html

<!doctype html>
<html lang="en">

<title>jQuery UI Autocomplete - Default functionality</title>

<script src="auto.js">

</script>
<script>
var no_of_rows = 6;
var upto = no_of_rows + 1 ;
var total_rows = total_rows ;


$(document).ready(function(){
$('.numbersOnly').keyup(function () { 
this.value = this.value.replace(/[^0-9\.]/g,'');
});
  $("#but").click(function(){
   var no_of_extra = parseInt($("#no_of_extra").val() , 10);
    total_rows = no_of_rows + no_of_extra;
    $("#mytable").find("tr:gt("+upto+")").remove();


    for ( var i = no_of_rows + 1 ; i <= total_rows ; i ++)
    {
        var tag = "<tr> <td>" + i + "</td> <td> <input class = \"tags\" id = \"T"+i+"\"> </td>";
        $("#mytable").append(tag);
/*
        $( "#T" + i ).autocomplete({
            source: availableTags 
        });
*/

    }
  });

});



</script>
</head>

        <input type="text" id="no_of_extra" class="numbersOnly" >

        <input type="button" id = "but" value="Add" >

    <table id="mytable">
        <tr><th>no</th><th>type</th><tr>
        <tr><td>1</td><td><input class ="tags" id = "T1"></td></tr>

        <tr><td>6</td><td><input class ="tags" id = "T6"></td></tr>

    </table>

</body>
</html>

auto.js

$(function() {
var availableTags = [
"Australia",
"Belgium",
"Canada",
"Denmark",
"Ethiopia",
"France"
];
$( ".tags" ).autocomplete({
source: availableTags 
});
});

在 auto.js 文件之外包含 availableTags 数组，如下所示：

<script>

    var availableTags = [
    "Australia",
    "Belgium",
    "Canada",
    "Denmark",
    "Ethiopia",
    "France"
    ];

    var no_of_rows = 6;
    var upto = no_of_rows + 1 ;
    var total_rows = total_rows ;


    $(document).ready(function(){

    $( ".tags" ).autocomplete({
    source: availableTags 
    });

    $('.numbersOnly').keyup(function () { 
    this.value = this.value.replace(/[^0-9\.]/g,'');
    });
      $("#but").click(function(){
       var no_of_extra = parseInt($("#no_of_extra").val() , 10);
        total_rows = no_of_rows + no_of_extra;
        $("#mytable").find("tr:gt("+upto+")").remove();


        for ( var i = no_of_rows + 1 ; i <= total_rows ; i ++)
        {
            var tag = "<tr> <td>" + i + "</td> <td> <input class = \"tags\" id = \"T"+i+"\"> </td>";
            $("#mytable").append(tag);

            $( "#T" + i ).autocomplete({
                source: availableTags 
            });


        }
      });

    });



    </script>
