jee6 学习笔记 4 - CRUD 2: View Details, Primefaces row selection
jee6 学习笔记 4 - CRUD 2: View Details, Primefaces row selection
- 博客分类:
- JEE
screenshot of view details button:
screenshot of view details of selected row:
updated backing bean "StudentSearch.java":
1. added property "Student selectedStudent"
2. added getter/setter for it, as selection action listener
updated model Student: missing property "age" before )-;
updated page "student/studentSearch.xhtml"
1. added a <p:commandButton> to enable row selection
2. added a <p:dialog> to enable view student details
小姐一下:
1, Primefaces provides a few options of row selection to enable row operations.
2, we used basic single row selection to view details of the selected row.
3, basic row selection can be achieved by <p:commandButton>.
3.1, update=":form:idDisplay": use attribute "update" to set the dom id of the element to hold row data. the value corresponds to the element id of <h:panelGrid>, which is a sub-element included in <p:dialog>.
3.2 oncomplete="wvStuDialog.show()": use attibute "oncomplete" to activate the display of the dialog. the value corresponds to attribute "widgetVar" of <p:dialog>.
4, Primefaces makes it pretty easy.
5, it should be noted that the model object "Student" does not implement any extra interfaces at all - it's a simple POJO. So is the backing bean "StudentSearch".
