Sending and receiving data

This section answers the question: What is sent to the server?

Sending the modified value

when editing has finished, the new value is sent to the server using an ajax call.

The new value is sent as a parameter named 'value' using POST to the url specified. There may be additional parameters sent as follows.

  • If the element has an id then it will be sent with parameter name 'id'.
  • If 'data-attribute' is set (or the config setting 'attribute' is present) then its value is sent under the parameter name 'attribute'.
  • If 'data-object' is set (or the 'object' setting), then its value is sent under the parameter name 'object'.

The returned value is used to set the text within the editable element and replace the editing control. So if the editing format and the display format differ, then it is the display format that is returned.

For example, for a select dropdown, it will be the text of the selected option.

Loading data

When 'data-loadurl' is used, then a GET call is made to the server with exactly the same parameters as in the previous section, except that there is no 'value' parameter to send.

The value returned is used to initialise the editing field, and so it must be in its editing format if that differs from the display format.

Data formats for each input type


Takes text and so there is normally nothing special to do, the editing and display formats are the same.

An exception might be is cases such as when the data is held in markdown or a variety of wiki text. In this case you might want to edit the wiki text, but display html. So on saving the changed wiki text, the server will format to html and return that as the display text. To display html as formatted areas, rather than literal html (with the angle brackets) you need to set textOnly to false.


This is exactly the same considerations as for 'input'.


The display format is the text of the selected option. However the editing format is a json list of all the possible options so that a dropdown can be constructed.

The option list is formatted as in this example

[["1", "Red"], ["2", "Green", 1], ["3", "Blue"]]

Above there are three options 1, 2 and 3, with the values 'Red',' Green' and 'Blue'. The value 2/Green is currently selected.

If none of the options are marked as selected then it will attempt to work it out by looking at the existing text in the element.

When a selection is made to say, Blue, then the value '3' will be posted to the server, and the display value 'Blue' will be returned in the normal case.
