No Eval

By default, this renderer allows the compilation and execution of JavaScript (eval) through the following features.

  • Custom Conditionals
  • Custom Validation
  • Custom Templates (like with EditGrid)

For some implementations, the need to turn off “eval” is a requirement. This can be done, at the expense of the features outlined above, using the following code.

FormioUtils.Evaluator.noeval = true;

This will force the builder to not show the configurations for these elements as well as render things that allow custom templates with the default templates, like the following.

FormioUtils.Evaluator.noeval = true;
Formio.createForm(document.getElementById('formio'), {
  components: [
      {
        label: 'Children',
        key: 'children',
        type: 'editgrid',
        input: true,
        components: [
          {
            label: 'First Name',
            key: 'firstName',
            type: 'textfield',
            input: true
          },
          {
            label: 'Last Name',
            key: 'lastName',
            type: 'textfield',
            input: true
          },
          {
            label: 'Gender',
            key: 'gender',
            type: 'select',
            input: true,

                  value: 'other',
                  label: 'Other'
                }
              ]
