无法在 jquery 自动完成中获取所选项目
Cannot get selected item in jquery autocomplete
使用 Jquery 自动完成 UI 小部件,我有以下代码通过外部 php 获取 suburbs/postcodes 列表:
<script>
$(function() {
$("#suburb").autocomplete({
minLength:3, //minimum length of characters for type ahead to begin
source: function (request, response) {
$.ajax({
type: 'POST',
url: 'resources/php/helpers.php', //your server side script
dataType: 'json',
data: {
suburb: request.term
},
success: function (data) {
//if multiple results are returned
if(data.localities.locality instanceof Array)
response ($.map(data.localities.locality, function (item) {
return {
label: item.location + ', ' + item.postcode,
value: item.location + ', ' + item.postcode
}
}));
//if a single result is returned
else
response ($.map(data.localities, function (item) {
return {
label: item.location + ', ' + item.postcode,
value: item.location + ', ' + item.postcode
}
}));
},
select: function (event, ui) {
alert("SELECT");
$('#postCode').val("POSTCODE");
return true;
}
});
}
});
});
</script>
自动完成本身运行良好,我得到了匹配列表,但是 'select' 部分不起作用,即,我需要将另一个输入文本值设置为所选值,但即使在上面代码,警报对话框不会被调用 - 我看到的各种语法让我有点困惑,所以我不确定我在这里做错了什么。
select
函数应该在发送给ajax方法的对象之外。
试试这个:
$(function() {
$("#suburb").autocomplete({
minLength:3, //minimum length of characters for type ahead to begin
source: function (request, response) {
$.ajax({
type: 'POST',
url: 'resources/php/helpers.php', //your server side script
dataType: 'json',
data: {
suburb: request.term
},
success: function (data) {
//if multiple results are returned
if(data.localities.locality instanceof Array)
response ($.map(data.localities.locality, function (item) {
return {
label: item.location + ', ' + item.postcode,
value: item.location + ', ' + item.postcode
}
}));
//if a single result is returned
else
response ($.map(data.localities, function (item) {
return {
label: item.location + ', ' + item.postcode,
value: item.location + ', ' + item.postcode
}
}));
}
});
},
select: function (event, ui) {
alert("SELECT");
$('#postCode').val("POSTCODE");
return true;
}
});
