Struts1.2.4学习心得!(三)

第三次学习:

1.从Bean中取得数组并显示(其中intArray为BEAN返回的数组)

java代码:

1 2 <jsp:useBean id="test3" scope="page" class="org. apache. struts. webapp. exercise. TestBean" /> 3 <table border=" 1"> 4 <tr> 5 <th>Correct Value</th> 6 <th> Array Result</th> 7 <th>Indexed Result</th> 8 </tr><% for ( int index = 0; index < 5; index++ ) { %> 9 <tr> 10 <td> 11 <%= index * 10 %> 12 </td> 13 <td> 14 <bean:write name="test3" property= '<%= "intArray[" + index + "]" %>' /> 15 </td> 16 <td> 17 <bean:write name="test3" property= '<%= "intIndexed[" + index + "]" %>' /> 18 </td> 19 </tr><% } %> 20 </table> 21

2.嵌套Bean的属性的显示(nested为TestBean的一个属性,nested为一个bean.显示nested中的属性值)

java代码:

1 2<jsp:useBean id="test5" scope="page" class="org. apache. struts. webapp. exercise. TestBean" /> 3 <table border=" 1"> 4 <tr> 5 <th>Data Type</th> 6 <th>Correct Value</th> 7 <th>Test Result</th> 8 </tr> 9 <tr> 10 <td> boolean</td> 11 <td> 12 <jsp:getProperty name="test5" property="booleanProperty" /> 13 </td> 14 <td> 15 <bean:write name="test5" property="nested. booleanProperty" /> 16 </td> 17 </tr> 18 <tr> 19 <td> double</td> 20 <td> 21 <jsp:getProperty name="test5" property="doubleProperty" /> 22 </td> 23 <td> 24 <bean:write name="test5" property="nested. doubleProperty" /> 25 </td> 26 </tr> 27 <tr> 28 <td>float</td> 29 <td> 30 <jsp:getProperty name="test5" property="floatProperty" /> 31 </td> 32 <td> 33 <bean:write name="test5" property="nested. floatProperty" /> 34 </td> 35 </tr> 36 <tr> 37 <td> int</td> 38 <td> 39 <jsp:getProperty name="test5" property="intProperty" /> 40 </td> 41 <td> 42 <bean:write name="test5" property="nested. intProperty" /> 43 </td> 44 </tr> 45 <tr> 46 <td>long</td> 47 <td> 48 <jsp:getProperty name="test5" property="longProperty" /> 49 </td> 50 <td> 51 <bean:write name="test5" property="nested. longProperty" /> 52 </td> 53 </tr> 54 <tr> 55 <td>short</td> 56 <td> 57 <jsp:getProperty name="test5" property="shortProperty" /> 58 </td> 59 <td> 60 <bean:write name="test5" property="nested. shortProperty" /> 61 </td> 62 </tr> 63 <tr> 64 <td> String</td> 65 <td> 66 <jsp:getProperty name="test5" property="stringProperty" /> 67 </td> 68 <td> 69 <bean:write name="test5" property="nested. stringProperty" /> 70 </td> 71 </tr> 72 </table> 73

3.嵌套bean中数组的显示(nested为TestBean的一个属性,nested为一个bean.显示nested中的数组的属性值)

java代码:

1 2 <jsp:useBean id="test6" scope="page" class="org. apache. struts. webapp. exercise. TestBean" /> 3 <table border=" 1"> 4 <tr> 5 <th>Correct Value</th> 6 <th> Array Result</th> 7 <th>Indexed Result</th> 8 </tr><% for ( int index = 0; index < 5; index++ ) { %> 9 <tr> 10 <td> 11 <%= index * 10 %> 12 </td> 13 <td> 14 <bean:write name="test6" property= '<%= "nested.intArray[" + index + "]" %>' /> 15 </td> 16 <td> 17 <bean:write name="test6" property= '<%= "nested.intIndexed[" + index + "]" %>' /> 18 </td> 19 </tr><% } %> 20 </table> 21
