我有一个要启用自动完成功能的输入字段。我已在下面的标题部分中添加了
。<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" />
<script type="text/javascript"
src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
字段
<form:input path="customer" maxlength="50" id="customer"
placeholder="Customer Name" cssClass="form-control"
required="true" />
Js
$( "#customer" ).autocomplete({
minLength: 2,
dataType: "json",
cache: false,
source : function(request, response) {
$.ajax({
url : "http://localhost:8888/rider/get_rider",
dataType : "json",
method:'GET',
data : {
term : request.term
},
success: function(data){
response(data.map(function(value){
console.log(value);
return {
label: value.name,
value: value.name,
description: value.name
};
}));
}
});
}
});
我可以看到从控制器发回了有效的json响应。
控制器
@GetMapping(value="/get_rider",produces = "application/json")
public List<RiderGroupDTO> getCustomerName(@RequestParam("term") String query){
List<RiderGroupDTO> li=new ArrayList<>();
li=riderGroupService.findAllGroups();
return li;
}
响应
{id: 1, name: "Admin", description: "Admin group to send coupons to all "}
{id: 2, name: "food", description: "food coupons"}
问题在于,尽管响应已发送,但未在jsp上显示。即使在浏览器控制台上也没有错误。怎么了?
答案 0 :(得分:1)
必须在本地服务器上进行测试。这似乎可以从php页面取回JSON。我认为您返回的JSON可能是一个问题。我没有得到JSON。我不确定自动完成功能的真正工作原理,因此您可能不得不尝试一下,因为它只是显示所有“名称”值,而不是按我键入的内容进行过滤。
这是我拥有的服务器。

$( "#customer" ).autocomplete({

dataType: "json",
cache: false,
source : function(request, response) {
$.ajax({
url : "test1.php",
dataType : "json",
method:'POST',
data : {},
success: function(data){
response(data.map(function(value){
console.log(value);
return {
label: value.name,
value: value.name,
description: value.name
};
}));
}
});
}
});
});
</script>
JSON响应,实际上是一个对象数组,我认为您需要在名称/值对周围加上引号。
[{"id": "1", "name": "Admin", "description": "Admin group to send coupons to all"},
{"id": "2", "name": "food", "description": "food coupons"}]
