How to load multiple fields to form from database with jquery?

In my web-application i have a form which contains about 25 fields. Users will create this form and f开发者_高级运维orm fields value will transfer to database tables. But i also need an editing function for this form. People will push button, form will load and i need form fields values to load from database. I know that i can load data to form field with jquery load function:

$('#text_field').load('text_field_value.php');

But when i have 25 fields, then i need to do 25 connections to database (1 connection per file), so my form loading very slow.

Is there any solution, to speed up the process?

Thanks in advance.

Perhaps you should load the field values using one ajax request so that you are only using one connection to the database and then as Pekka said return a JSON Array. Then using jQuery go through the JSON Array putting the values into the correct fields.

So use .getJSON/.post/.ajax instead of .load

EDIT: Example JSON Array, with objects for each field

[
    {
        'field'      : '#field1',
        'fieldType'  : ':text',
        'fieldValue' : 'Test Value'
    },
    {
        'field'      : '[name=field2]',
        'fieldType'  : ':radio',
        'fieldValue' : '#item1'
    },
    {
        'field'      : '#field3',
        'fieldType'  : 'select',
        'fieldValue' : 5
    },
    {
        'field'      : '#field4',
        'fieldType'  : ':checkbox',
        'fieldValue' : true
    }
]

You can then loop through the array as follows:

for(i in array)
{
    /***
     * access each object as follows:
     * array[i].field
     */
    .....
}
