Question

There is a json(#json) like as follow, in student section, first two one is a group, last two one is a group.(group by a set of no. like no.1 and no.2 are one set).
The problem is i need fetch the data from student section and make 2 table (depend on how many set of no., 2 in this example). How to modify the json data structure programmatically that i can fetch the data to do above thing?

The table(#table1) look like :
no. name
1 tom
2 jacky

no. name
1 tom
2 jacky

#json

{
"people": {
    "student": [{
        "name": "tom"
        "no.": "1"
        "other": "a"
    },{
        "name": "tom"
        "no.": "1"
        "other": "e"
    },{
        "name": "jack"
        "no.": "2"
        "other": "d"
    },{
        "name": "tom"
        "no.": "1"
        "other": "c"
    },{
        "name": "tom"
        "no.": "1"
        "other": "d"
    },{
        "name": "jack"
        "no.": "2"
        "other": "g"
    }]      
}}

here is my jsRender template:

    <table>      
    <thead>
        <tr><td>Table 1</td></tr> 
        <tr><td>no.</td><td>name</td></tr> 
    </thead> 
    <tbody>
    {{for student}}
        <td>{{>no.}}</td>
        <td>{{>name}}</td>
    {{/for}}
    </tbody>
</table>

It will output:

no. name
1 tom
2 jacky
1 tom
2 jacky

How can i modify my template to make the output like #table1

You need something like this:

var yourJSON; // All JSON data
var studentData = yourJSON.people.student; // Student array
var tableIndex = 1; // Index for table name

// Loop to print student data
for (var i = 0, length = studentData.length; i < length; i++) {
    if (studentData[i]['no.'] == '1') {
        if (tableIndex > 1) {
            print('</tbody></table>');
        }
        print('<table>' +
            '<thead>' +
                '<tr>' +
                    '<td>Table ' + tableIndex + '</td>' +
                '</tr>' + 
                '<tr>' +
                    '<td>no.</td>' +
                    '<td>name</td>' +
                '</tr>' + 
            '</thead>' +
            '<tbody>');
        tableIndex++;
    }
    print('<tr><td>' + studentData[i]['no.'] + '</td>');
    print('<td>' + studentData[i]['name'] + '</td></tr>');
}

print('</tbody></table>'); // Closing the last table

I don’t know how your template engine works so I used the print function to show what is needed to be added in the template.
