我正在尝试将以下代码改编为我的应用程序。 Multiple Autocomplete jsfiddle jsfiddle工作 - 我的PHP应用程序没有。
我的应用程序是基于PHP的Xataface应用程序,我已经添加了自定义移动创建页面。我想从mysql获取建议列表。
它适用于第一个建议,然后弹出逗号。
问题:问题是在我的应用程序中它没有显示第二个条目的建议列表(在逗号之后)。
我做了很多谷歌搜索,我没有看到可能帮助我的相关页面。
有人可以帮我看看第二次及以后进入该领域的建议清单吗?
以下是我的代码......
我的表格如下:

/* Free connection resources. */
//mysql_close($conn);
/* Toss back results as json encoded array. */

当我阅读更多内容并进行更多搜索时,我在jquery ui网站上找到了多个远程自动完成代码。有趣的是你可以长时间搜索和阅读,而不会遇到一些明显有用的信息。
jquery ui website .. http://jqueryui.com/autocomplete/#multiple-remote
我使用下面的示例代码编辑它以适合我的应用程序。
现在可以使用,并在我的应用程序中解决了我的问题。
$(function() {
function split( val ) {
return val.split( /,\s*/ );
}
function extractLast( term ) {
return split( term ).pop();
}
$( "#birds" )
// don't navigate away from the field on tab when selecting an item
.bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB &&
$( this ).data( "ui-autocomplete" ).menu.active ) {
event.preventDefault();
}
})
.autocomplete({
source: function( request, response ) {
$.getJSON( "search.php", {
term: extractLast( request.term )
}, response );
},
search: function() {
// custom minLength
var term = extractLast( this.value );
if ( term.length < 2 ) {
return false;
}
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function( event, ui ) {
var terms = split( this.value );
// remove the current input
terms.pop();
// add the selected item
terms.push( ui.item.value );
// add placeholder to get the comma-and-space at the end
terms.push( "" );
this.value = terms.join( ", " );
return false;
}
});
});
