How to set Character limit for a dynamic text entry field in Articulate Storyline

When we think of developing simulation based training, Adobe Captivate is the perfect tool to choose. But for some reason, we have to develop simple simulation based training using Articulate Storyline. The project we were working was on software training for sales team explaining how the product works. And in-between the training, few basic steps were added in which user has to interact.

While working on this project, we came across a requirement to set the character limit for an input field. By default Storyline doesn’t has this feature. Hence, we did customization using JavaScript.

The steps are as follows:

Step 1

  • Add the input fields on the screen. In this example, we used 3 input fields – two text entry fields and one numeric entry field.

Step 8

  • In the JavaScript panel, paste the below given JavaScript code and set When Timeline Starts. Then click OK.

Note: If you want to add or delete the input fields on the screen, you must add input variable names inside the square braces.

Example:

var fields = ["twenty_chars", "twelve_chars","fifteen_chars"]

In the code, you can set maximum characters for respective input text entry field.

Examples:

$("#twenty_chars").attr("maxlength","20");
        $("#twelve_chars").attr("maxlength","12");
        $("#fifteen_chars").attr("maxlength","15");

var fields = ["twenty_chars", "twelve_chars", "fifteen_chars"];
(function setMaxChars(fields) {
    fields.forEach(function (field, field_index) {
        $('[placeholder=' + field + ']').attr('id',field);
        $("#twenty_chars").attr("maxlength","20");
        $("#twelve_chars").attr("maxlength","12");
        $("#fifteen_chars").attr("maxlength","15");
        $('[placeholder=' + field + ']').attr('placeholder', '');
    });
})(fields);

Step 9

In the trigger layer, the “Execute JavaScript” trigger is added.
