     <link rel="stylesheet" type="text/css" href="http://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css"/>
      <link rel="stylesheet" href="styles/token-input.css" type="text/css" />
      <script type="text/javascript" src="src/jquery.tokeninput.js"></script>
<script>
      var country_list=[ 
{id: 1, name: "UK"}, 
{id: 2, name: "CANADA"}, 
{id: 3, name: "IRELAND"}, 
{id: 4, name: "SINGAPORE"}, 
{id: 5, name: "AUSTRALIA"}, 
{id: 6, name: "NEWZEALAND"}, 
{id: 7, name: "SWITZERLAND"}, 
{id: 8, name: "CYPRUS"}, 
{id: 9, name: "FRANCE"}, 
{id: 10, name: "MALAYSIA"}, 
{id: 11, name: "ITALY"}, 
{id: 12, name: "SWEDEN"}, 
{id: 13, name: "GERMANY"}, 
{id: 14, name: "USA"}, 
{id: 15, name: "DUBAI"}, 
{id: 16, name: "SPAIN"}, 
{id: 17, name: "LITHUANIA"}, 
{id: 18, name: "NETHERLANDS"}, 
{id: 19, name: "LATVIA"}, 
{id: 20, name: "SOUTH AFRICA"}, 
{id: 21, name: "OTHERS"} 
]; 
var selected_countries=<?php echo json_encode(explode(",",$country));?>; 
//alert(selected_countries);
var populate_list=[]; 
var index; 
for (index = 0; index < country_list.length; ++index) { 
console.log(country_list[index]); 
if(selected_countries.indexOf(country_list[index].name)>-1){ 

populate_list.push(country_list[index]); 
} 
} 
var prepopulate = { 
prePopulate : populate_list 
}; 

$("#country").tokenInput(country_list,prepopulate);
</script>

HTML代码

 <input type="text" name="country"  id="country">

为了保存结果，我使用了数据库中的所有选定文本

AJAX代码

var arr1 = $('#country').tokenInput("get");
            var names1 = [];
            $.each(arr1, function(i, obj)
            {
             names1.push(obj.name);
            });
            var country=names1.join();

结果数据库端 AND UI 端

prePopulate Prepopulate the tokeninput with existing data. Set to an array of JSON objects, eg: [{id: 3, name: "test"}, {id: 5, name: "awesome"}] to pre-fill the input.

var country_list=[ 
{id: 1, name: "UK"}, 
{id: 2, name: "CANADA"}, 
{id: 3, name: "IRELAND"}, 
{id: 4, name: "SINGAPORE"}, 
{id: 5, name: "AUSTRALIA"}, 
{id: 6, name: "NEWZEALAND"}, 
{id: 7, name: "SWITZERLAND"}, 
{id: 8, name: "CYPRUS"}, 
{id: 9, name: "FRANCE"}, 
{id: 10, name: "MALAYSIA"}, 
{id: 11, name: "ITALY"}, 
{id: 12, name: "SWEDEN"}, 
{id: 13, name: "GERMANY"}, 
{id: 14, name: "USA"}, 
{id: 15, name: "DUBAI"}, 
{id: 16, name: "SPAIN"}, 
{id: 17, name: "LITHUANIA"}, 
{id: 18, name: "NETHERLANDS"}, 
{id: 19, name: "LATVIA"}, 
{id: 20, name: "SOUTH AFRICA"}, 
{id: 21, name: "OTHERS"} 
]; 

var selected_countries=<?php echo json_encode(explode($country));?>; 
var populate_list=[]; 
var index; 
for (index = 0; index < country_list.length; ++index) { 

if(selected_countries.indexOf(country_list[index].name)>-1){ 
populate_list.push(country_list[index]); 
} 
} 
var prepopulate = { 
prepopulate : populate_list 
}; 

 $("#country").tokenInput(country_list,prepopulate);

Answer 2

将您的输入文本框更改为以下内容：

<input type="text" name="country"  id="country" value='<?php echo  $country; ?>' data-country='<?php echo  $country; ?>'>

然后添加 prePopulate 参数，如下所示：

prePopulate: $('#country').data('country')
