jQuery 和 Javascript 新手，不确定如何替换此自动完成功能

// autocomplete enablement
    var availableAttributes = [
      "account_address",
      "account_address_city",
      "account_address_country",
      "account_address_state",
      "account_address_street1",
      "account_address_street2",
      "account_address_zip",
      "account_email",
      "account_login",
      "account_name",
      "account_number",
      "account_telephone"
    ];

在

  $(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID
// autocomplete enablement
    var availableAttributes = [
      "account_address",
      "account_address_city",
      "account_address_country",
      "account_address_state",
      "account_address_street1",
      "account_address_street2",
      "account_address_zip",
      "account_email",
      "account_login",
      "account_name",
      "account_number",
      "account_telephone"
    ];
    $( "input[name^='mytext']" ).autocomplete({
        source: availableAttributes
    });     

    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append($('<div><input type="text" name="mytext[]"/><a href="#" class="remove_field">Remove</a></div>').find(":text").autocomplete({
        source: availableAttributes
    })); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    })


  });

使用（jQuery Jason 远程数据源自动完成。链接http://jqueryui.com/autocomplete/#remote-jsonp）

  $(function() {
    function log( message ) {
      $( "<div>" ).text( message ).prependTo( "#log" );
      $( "#log" ).scrollTop( 0 );
    }

    $( "#city" ).autocomplete({
      source: function( request, response ) {
        $.ajax({
          url: "http://gd.geobytes.com/AutoCompleteCity",
          dataType: "jsonp",
          data: {
            q: request.term
          },
          success: function( data ) {
            response( data );
          }
        });
      },
      minLength: 3,
      select: function( event, ui ) {
        log( ui.item ?
          "Selected: " + ui.item.label :
          "Nothing selected, input was " + this.value);
      },
      open: function() {
        $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
      },
      close: function() {
        $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
      }
    });
  });

【问题讨论】：

你打算使用什么网络服务？
@BG101, html css javascript, jQuery, php, mysql
我的意思是抱歉。
@url?，我不确定你在问什么。我计划通过 JSON 数据源将 jQuery 自动完成应用于上述动态驱动的表单。您在这里有一个工作示例 [链接] (jqueryui.com/autocomplete/#remote-jsonp)
jsonp 必须来自某个地方。在那个例子中是 gd.geobytes.com/AutoCompleteCity

标签： javascript jquery html forms autocomplete

【解决方案1】：

这是您发布的工作示例

$(document).ready(function() {    
   
$(".myText").autocomplete({

source: function (request, response) {
 jQuery.getJSON(
	"http://gd.geobytes.com/AutoCompleteCity?callback=?&q="+request.term,
	function (data) {
	 response(data);
	}
 );
},
minLength: 3
 });

var max_fields = 10; //maximum input boxes allowed
var wrapper = $(".input_fields_wrap"); //Fields wrapper
var add_button = $(".add_field_button"); //Add button ID

var x = 1; //initlal text box count
$(add_button).click(function(e) { //on add input button click
    e.preventDefault();
    if (x < max_fields) { //max input box allowed
        x++; //text box increment
        // $(wrapper).append('<div><input id="' + x + '" type="text" name="mytext"/><a href="#" class="remove_field">Remove</a></div>'); //add input box
        $(wrapper).append('<div>' + '<input id="' + x + '" type="text" class="myText" id="myText"><br>' + '<textarea name="desc[]"></textarea>' + '<a href="#" class="remove_field">Remove</a>' +'</div>');
        
        $("#" + x).autocomplete({

source: function (request, response) {
 jQuery.getJSON(
	"http://gd.geobytes.com/AutoCompleteCity?callback=?&q="+request.term,
	function (data) {
	 response(data);
	}
 );
},
minLength: 3
 });
    }
});

$(wrapper).on("click", ".remove_field", function(e) { //user click on remove text
    e.preventDefault();
    $(this).parent('div').remove();
    x--;
});
});

<link href="https://code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<div class="input_fields_wrap">
        <button class="add_field_button">Add More Fields</button>
        <div><input type="text" class="myText" name="myText" id="myText"></div>
        <textarea name="desc[]"></textarea>
    </div>

【讨论】：

需要将上面的自动补全替换为jqueryui.com/autocomplete/#remote-jsonp
我已经更新了它，如果你想使用远程选项加载它，你需要编写自己的页面来返回 json。但这一个适用于 jquery 示例
你很亲密。是的，它有效，但仅适用于第一个字段。单击“添加更多字段”按钮后，自动完成功能将停止在第二个字段上工作。在我接受你的回答之前，你能纠正一下吗？
