NAME

x6.json.process

FUNCTION

The Javascript method x6.json.execute is the final step in sending and receiving JSON requests. This routine does the following:

• Any HTML sent back via PHP x4HTML replaces the innerHTML of the named items (actually item Ids are used).
• Any script sent back via PHP x4Script is executed.
• Any data sent back via PHP x4Data is placed into x6.data.
  

EXAMPLE

This example shows how you can retrieve table data and then process it:

      <script>
      x6.json.init('x4Page','myCustomPage');
      x6.json.addParm('x4Action','getStates');
      // x6.json.execute will return false on errors
      if(x6.json.execute()) {
         // x6.json.process puts everything in its place...
         x6.json.process();
         // ...so that we can handle the returned data
         for (var idx in x6.data.states) {
            // do something
         }
      }
      <script>

This code requires the following PHP code on the server:

      <?php
      # this is file application/x4myCustomPage.php
      class x4myCustomPage extends androX4 {
          function getStates() {
              $states = SQL("Select * from states");
              x4Data('states',$states);
          }
      }
