Number Range Slider Form Element

The Number Range Slider form element allows the user to select a range of numbers using a slider control or by typing numbers in the Start and End fields.

To use a Number Range Slider, drag the Start handle to the left or right (). The Start field box shows the currently selected number. Then drag the End handle to the left or right (). The End field box shows the currently selected number. Alternatively, the user can use the arrows to change the number () or type a number directly into the Start or End field boxes.

The Number Range Slider can also be manipulated using keyboard shortcuts. To use keyboard shortcuts, select the Number Range Slider form element with a left-click. Alternatively, you can use the Tab key to toggle between controls until the desired element's control has been selected. You can reverse the tabbing toggle direction by clicking Shift+TAB. Once the desired control has been selected, use the arrow keys to increase or decrease the value. This works for the manual input fields as well as the slider's endpoints.

The Start and End field's numeric value is increased with the Up arrow key and decreased with the Down arrow key.

The slider's endpoints are manipulated with the arrow keys; Down or Left to decrease the value and Up or Right to increase the value.

Number Range Slider Properties

The Properties table describes the properties of the Number Range Slider form element.

The type of a property defines what types of values the property can have. Many properties are type string, which means that the property's value is text. Boolean properties can be true or false. Some properties have more than one possible type.

Property names in Workflow Designer's Properties panel are written using the capitalization and spacing of a title. Property names in expressions are valid JavaScript identifiers and start with a lower case letter.

In the table below:

Expressions are case sensitive. When you access a form element property in an expression, you must use the correct capitalization.

Properties of the Number Range Slider Form Element

Decimal Places

Type: Number

The number of decimal digits to show, for example:

  • 0 shows integers (...-2, -1, 0, 1, 2...), for example, 154 or -12;

  • 1 shows one decimal place (...-0.2, -0.1, 0, 0.1, 0.2...), for example, 1.9 or -52.0;

    2 shows two decimal places (...-0.02, -0.01, 0, 0.01, 0.02...), for example, 94800.01 or -16.99;

    and so on.

The value cannot be negative.

Default Values

Type: String

The numbers that appear in the Start and End fields. This controls the initial end points of the range slider. If you leave the Default Value blank, the Start and End fields will default to the Minimum and Maximum values.

Each Default Value is entered one per line (). The first number on the first line represents the default lowest value () of the range. The second number on the second line represents the default highest value () in the range. Exactly two (2) values are processed. Entering one (1) value will be ignored by the system. Entering three (3) or more values results in the system processing the first two (2) values only.

 

Default values example for the Number Range Slider

The default Start value cannot be less than the Minimum value.

The default End value cannot be greater than the Maximum value.

Description

Type: String

A description of the element. The description appears below the element's title.

You can use the Description property to describe what the element represents or to provide instructions to the user about how to use the element.

You can format the description using Markdown.

Element ID

Type: String

The element's ID, which is used in other form elements and activities to access the element's properties, including the user's input. The ID must be unique across all elements in the form.

You cannot set the value of the Element ID property in an expression—you can only use the value that you configured for it. To use the Element ID property in an expression:

${Display Form ID}.state.{Element ID}.{property name}

For example:

$form1.state.numberRangeSlider1.visible

Enabled

Type: Boolean

Name in Properties Panel: Enabled

Name to Use in Expressions: enabled

Indicates whether the Number Range Slider element is enabled in the running workflow. When Number Range Slider is enabled, the user can select a number range. Whena Number Range Slider is disabled, the user can see the Number Range Slider element, but cannot interact with it. Disabled elements appear dimmed or shaded in the running workflow.

By default, Number Range Slider elements are enabled. To disable a Number Range Slider element, clear the Enabled checkbox. You may want to change the property's value at run time depending on the user's input in a previous form element.

To access the enabled property in an expression:

${Display Form ID}.state.{Element ID}.enabled

For example:

$form1.state.numberRangeSlider1.enabled

error

Type: String | MarkdownRef

Indicates whether an error occurred in the element.

We recommend using the Set Form Element Error and Clear Form Element Error activities to work with errors in form elements.

Maximum

Type: Number

The slider's maximum value. By default, the maximum value will be 100. The highest value you can set Maximum value to is JavaScript's maximum value.

Minimum

Type: Number

The slider's minimum value. By default, the minimum value will be 0 (zero). The lowest value you can set Minimum to is JavaScript's minimum value.

Number Format

Tick Marks shown on the Number Range Slider

Based on the screen resolution and the Step Size value, individual tick marks may not be distinguishable as they would visually blend together. In this case, they would appear as a thicker range slider line.

To access the Show Tick Marks property in an expression:
${Display Form ID}.state.{Element ID}.showTickMarks

For example:
$form1.state.numberRangeSlider1.showTickMarks

Step Size

Type: Number

The amount by which the number in the Start or End box increases or decreases each time the user drags the slider or clicks the up arrow or down arrow . If you leave Step Size blank or you enter a step size that is less than 1, the step size will be 1.

Number Range Slider Events

The following table describes the events associated with the form element.

Events for the Number Range Slider Form Element

load

The load event fires when the element finishes loading.

You can use the load event to set one or more of the element's properties at run time. For example, you could set the Number Range Slider's initial values.

change

The change event fires when the user moves the slider's endpoints, clicks an arrow , or clicks away from the Start or End box after modifying that box's value.

You can use the change event to create dependencies between form elements. For example, you could configure a change subworkflow that enables or disables other form elements depending on the user's selection.

The change event fires every time the user's selection changes by one Step Size. This means that the change subworkflow can run multiple times. Because of this, you should make sure that the change subworkflow is not computationally intensive or long running.

drag

The drag event is repeatedly fired while an input is dragged.

The drag event fires every time the user's selection changes by one Step Size. This means that the drag subworkflow can run multiple times. Because of this, you should make sure that the drag subworkflow is not computationally intensive or long running.
