primeface eg
枚举的处理：
putViewScope(“types”, Type.values());
<h:outputText value="#{msg['dms']['type']}" />
<p:selectOneMenu id="type" style="width:140px;"
value="#{viewScope.type}" converter="#{enumConverter}">
<f:selectItem itemLabel="" itemValue="" />
<f:selectItems value="#{viewScope.types}" var="type"
itemLabel="#{type.name}" itemValue="#{type}" />
p:selectOneMenu>input框赋值：
document.getElementById("orgChartForm:orgChartNodeIndex").value = index;多选框赋值：
var departmentOptions = document.getElementById("orgChartForm:department_input").options;
for(var i = 0; i < departmentOptions.length; i++){
if(departmentId == departmentOptions[i].value){
departmentOptions[i].selected = 'selected';
document.getElementById('orgChartForm:department_label').innerText = departmentOptions[i].text;
break;
}
}枚举转换成JSON:
JSONArray types = new JSONArray();
for (Type type : Type.values()) {
JSONObject typeElement = new JSONObject();
try {
typeElement.put(type.toString(), type.getName());
types.put(typeElement);
} catch (JSONException e) {
e.printStackTrace();
}
}
putViewScope("types", types.toString());操作提示
@MessageRequired(type = MessageType.SAVE)数据库查询数目操作
@Query("select count(state) from DeceasedState state where state.serviceTransaction.serviceCode =:serviceCode")
public Long findCountQueryCode(@Param("serviceCode") ServiceCode serviceCode);JS方法传参到primeface后台
import javax.faces.context.FacesContext;
双击事件后传递对象
public void onRowSelect(SelectEvent event) {
Semester semester = (Semester) event.getObject();
semester.setIndex(semester.getIndex() + 1);
putViewScope("semesterObject", semester);
initSemester();
}

} p:selectManyCheckbox JS取值设值的解决方法
function getSelectManyCheckboxVal(name){
var nameStr = "[name='" + name + "']:checked";
var nameVal = [];
$(nameStr).each(function(){

});
return nameVal;
}
function setSelectManyCheckboxVal(name, values){
var nameStr = "[name='" + name + "']";
clearSelectManyCheckboxVal(name);
//set
$(nameStr).each(function(){
for(var i = 0; i < values.length; i++){
var boxVal = values[i];
if(boxVal == $(this).attr('value')){
