Ajax调用自动完成：
$(function() {
$("#businessCity").autocomplete(
{
source : function(c, b) {
$.ajax({
url : ctxPath + "/getCityNeighbourhood",
dataType : "json",
data : {
searchString : c.term,
itemType : "city"
},
success : function(d) {
b($.map(d.cityNeighbourhoodList, function(e) {
return {
label : e,
value : e
}
}))
}
})
},
minLength : 1
});
});
我的行动课程：
public class AutoCompleteAjax {
XYZ xyz = new XYZ();
private List<String> cityNeighbourhoodList=new ArrayList<>();
public String getCityNeighbourhood(){
HttpServletRequest request = ServletActionContext.getRequest();
String searchString = request.getParameter("searchString");
String itemType = request.getParameter("itemType");
cityNeighbourhoodList = xyz.getListOfCityStateNeighborhood(itemType, searchString);
return "success";
}
//getters & setters...
}
struts.xml条目的配置：
<action name="getCityNeighbourhood"
class="com.abc.xyz.ui.action.AutoCompleteAjax"
method="getCityNeighbourhood">
<result type="json" />
</action>
我在struts.xml中使用下面的包：
<package name="default" namespace="/" extends="struts-default, json-default">
奇怪的行为是在本地工作正常，但当我在生产服务器上尝试时 - 在输入我的文本字段时，Action类被调用但没有得到任何自动完成建议。当我尝试在FireFox调试器中调试时，我可以看到响应类型是html，而不是Json。
任何帮助将不胜感激。
＆GT;编辑：当我尝试使用FireFox调试器时 - 我得到的是整个代码，响应类型是html -

答案 0 :(得分：2)
url : ctxPath + "/getCityNeighbourhood",
如果项目在本地工作，但在服务器上工作，则此设置会产生问题。您必须验证ctxPath变量的值。
将其更改为：
url : "${pageContext.request.conetxtPath}/getCityNeighbourhood",
并尝试不使用contextPath：
url : "/getCityNeighbourhood",
