Learn the above Code as follows:

1. understanding of related labels

<EC: Some attributes in table:

Items: as mentioned earlier.

Action: This attribute is used to specify the targeted path for page turning, export, and query requests. You do not need to put the parameter after it, because EC will save the data in the request.

VaR: The table traverses all columns. You can use the VaR attributeBean corresponding to the current rowRange from set to page

Autoscaling deparameters: whether to enable the "auto-retain" feature. when filtering and sorting by pages, the form fields of the current page will be retained in the form of hiddeninput (passed to the new page ). optional; true/false (default: true ).

Retrieverowscallback: Specifies the paging mechanism used by the list.

Filterrowscallback specifies the filtering mechanism used by the list.

Sortrowscallback specifies the sorting mechanism used by the list.

Other tags can be found in the document.

 

<EC: attributes in row:

Recordkey: the unique primary key value of the record corresponding to the row.

 

<EC: attributes in column:

The alias of the alias column.

The value of the bean attribute corresponding to the current default row.

 

Ii. Check multiple row (ID) Operations

First<EC: Row attributesSet recordkey.

Second, a row is added.<EC: ColumnUsed to store a check box(Checkbox). Used to record all selected IDs.

 

Iii. <C: set definition method

<C: setvar = "ssexkey">

<C: outescapexml = 'false' value = "$ {tdestu. Sex}"> </C: Out>

</C: Set>

It is equivalent to defining a set. The key is ssexkey and the value is $ {tdestu. Sex}

 

4. about the problem of converting the database (0, 1) into a page (male, female) by gender

Ideas:

1. A map array is created in the background. Two maps (0, 1) correspond to (male, female ).

2. See a set on the page to store keys.

3. The map (key) sent from the page call shows men and women.
