How can one return the field type?

[Former Community Member]

Hi all,

How can I detect the field type in LiveCycle Designer ES using JavaScript?

If I have several different fields such as text fields & drop down lists which all have the same function assigned to them on their Enter event such as:

form.section_1.contents.text_field::enter - (JavaScript, client)

     functions.detect_field(this);

How do I return the type of field in the function call? I was hoping something like the following would work:

function detect_field(element){
     if(element.type == "text"){
          return "text field detected";
     } else if(element.type == "dropdown"){
          return "drop down list detected";
     }
}

Any help would be greatly appreciated!

Cheers,

Use the className property on a node. See the click event on the 'Validate' button on the attached. It iterates over a sub-form and identifies fields by className.

className cannot detect field types.

A solution is to resolveNode from the field object, checking for presence of field-type unique tags:

field.resolveNode("value.#text"))
field.resolveNode("ui.#checkButton")
field.resolveNode("ui.#numericEdit")
field.resolveNode("ui.#dateTimeEdit")
field.resolveNode("value.#decimal") && field.resolveNode("value.#decimal").leadDigits

You'll need to add additional tests for dropdowns and so on.

Or if you develop a naming convention for the fields that will include the type of field then you can interrogate the name of the field and derive what you want. For example:

btnSubmit - for a button

txtHeader - for a text object

fldName - for a field
