一. 前台(JS 面向对象)
1. 定义SearchView对象
function
SearchView() {
}
SearchView.prototype.setViewName =
function
(viewName) {
this
.viewName = viewName;
}
SearchView.prototype.setViewType =
function
(viewType) {
this
.viewType = viewType;
}
SearchView.prototype.conditionList =
new
Array();//******conditionlist是一个对象数组,注意它的用法
SearchView.prototype.setCriteria =
function
(criteria) {
this
.criteria = criteria;//******creteria
也是对象,具体更searchview对象定义类似,注意它的用法
}
SearchView.prototype.setTenant =
function
(tenant) {
this
.tenant = tenant;
}
2. 把值设进SearchView对象中
var
searchView =
new
SearchView();
searchView.setViewName(viewName);
searchView.setViewType(viewType);
searchView.setCriteria(criteria);
searchView.setTenant(tenant);
searchView.conditionList = conditionList;
3. 关于conditionList对象数组定义并设进SearchView对象中:
var
conditionList =
new
Array();
$.each(conditionList,
function
(index, condition) {
condition.fieldName = fieldName ;
condition.operatorTxt = operatorTxt ;
condition.fieldInfoTxt = fieldInfoTxt ;
condition.conditionValue =$.trim(condition.conditionValue);
});
searchView.conditionList = conditionList;
4. ajax 提交表单到后台,注意红色部分,这是需要JSON序列化string之后提交到后台然后解析为java bean
$.ajax({
url:home +
‘UserSearchViewAction.do?operation=update‘
,
type:
‘POST‘
,
dataType:
‘json‘
,
data:{
‘searchView‘
:
JSON.stringify(searchView)//*********注意,需要序列化对象后提交到后台
},
success:
function
(data) {
}
});
二、后台
1.定义相应的bean对象
searchView.java
String viewName;
String viewType;
List<Condition> conditionList;
String tenant;
Criteria criteria;
Condition.java
private
String conditionValue;
private
String fieldName;
// field name
private
String operatorTxt;
//operator value
private
String fieldInfoTxt;
//field value
Criteria.java
int
viewId;
String logicType;
String advanceFilter;
int
criteriaType;
2.处理传过来的json对象并转换为javabean
// parse jsonString to SearchView Object
String searchViewJSON = request.getParameter(
"searchView"
);
ObjectMapper objectMapper =
new
ObjectMapper();
SearchView searchView = objectMapper.readValue(searchViewJSON, SearchView.
class
);
OK 到目前位置,json转换为javabean的例子就做完了,最后展示下json对象实例
{
"viewName"
:
"t1"
,
"viewType"
:
"Dynamic"
,
"criteria"
: {
"logicType"
:
"AND"
,
"advanceFilter"
:
"1"
},
"tenant"
:
"DarlenSC"
,
"conditionList"
: [
{
"fieldName"
:
"Active"
,
"operatorTxt"
:
"Is not empty"
,
"fieldInfoTxt"
:
""
,
"fieldId"
:
"8"
,
"conditionValue"
:
""
,
"operation"
:
"ISNOTNULL"
,
"conditionOrder"
:
1
}
]
}
