Custom URL Manipulation of Text Fields (Check boxes)

Question

I have 1 Text field (Check boxes) in a Schema:

Above field have a Custom URL which points to a .NET page.

Values of Check box are each A, B, C.

I want to get and set the value, which is retrieved from the custom URL page.

I confirm to get value, but can't set value to text field (check box).

when setting value, catch below error message.

a.contains is not a function

I confirm to get and set value to simple text field (not check box).

So,I want to set value to text check box field.

I shown below my source code

get value

function getValue() {
var value = "";
var args = window.dialogArguments;
if (args) {
    var test = args.container.getField("test");
    if (test) {
        value = test.getValues();
    }
}
}

set value

function setLValue() {
var value = "";
var args = window.dialogArguments;
if (args) {
    var test = args.container.getField("test");
    if (test) {
        try
        {
          test.setValues([""]);
      }
      catch (e) {
          window.alert(e);        
        }
    }
}
}

Answer 1

The error message indicates that your array doesn't have the 'contains' method, which is something that is normally added to the Array prototype by the CME. But since the relevant files are not included in your custom URL page, you cannot just write "[]" and have it work.

The good news is that you can simply read the values first, which will give you an array that has the 'contains' method. Then you can add or replace the values as you see fit.

Example code:

function setLValue() {
        var field = window.dialogArguments.container.getField("test");
        var values = field.getValues();

        // Optional: clear the values
        values.splice(0, values.length);

        values.push("A");
        values.push("C");
        field.setValues(values);
}

Answer 2

I've tried using your code on my system but even getValues() will always only return me the first value in a multivalue text field. setValues() will only work if I pass a single value or an array with exactly one value; all other scenario's don't set any fields in the GUI.

Based on that I believe you would have to use the Anguilla framework to manipulate your field values; the previously mentioned cookbook has examples for field manipulations.

Edit: further inquiry into the nature of the getValues and setValues functions (sourcecode ftw) has lead me to the following solution:

test.setValues("a,b")

This will successfully set a multivalue checkbox field to both a and b. This must be an exact string match (so if value is A use A and not a).

To clear all values use

test.setValues("null")

It's rather counter-intuitive and afaict riddled with bugs (normal multi value fields don't work, only checkbox fields. Radio buttons are processed as multivalue fields which they are clearly not. Etc.)

Answer 3

I'm not sure but maybe you could set the checkbox this way:

test.getInputControl().item(0).checked = false;

Where test is a fieldbuilder with the checkbox field loaded.

You have to use logic to set true or false in order to set the checks, for example: to set "B":

test.getInputControl().item(1).checked = true;
