How to write to a label in version 9?

Hi,

I have a rather simple question. I am trying to set a label as a header in every form. On stage I am trying to set the label to stage.caption and on action to the action.caption.

I have managed to this with a simple javascript but the label changes the font to som kind of form standard. Is there an easier way to write to a label. Can I do this serverside?

This is my javascript function directly wrapped from 7.6: ltext is a calculated field with the action or stage caption.

function Header_OnLoad()

{

var headerlabel = eworkGetField("ltext");

document.getElementById("lheaderlabel").innerText = headerlabel;

}

Appreciate any help,

Best regards,

magnus

Magnus,

If you are happy with a field displaying this information rather than a label, you could set a calculated field with the formula:

If((ProcessContext.ActionName!=""), ProcessContext.ActionCaption, ProcessContext.StageCaption)

Note that this picks up the Action Caption and Stage caption rather then the name.

Version 9 builds the HTML for a label slightly differently than version 7.x.

In version 9, the HTML for a label is a span element with an ID matching the name of the label (no "e" prefix"). Contained within this span is another span with no ID, but has the style attributes you defined for the label. The innerHTML of this inner span is the label caption. You can verify this for yourself by opening the form in your browser, then use the "view source" option to take a look at the HTML of the page. Do a search for the name of your label, and you should find the markup pretty quickly.

When you set the innerHTML of the outer span (the one with the ID attribute) with text, you eliminate the inner span with the style information.

What you need to do, is set the innerHTML of the inner span. Unfortunately, this inner span does not have an ID attribute, so you can not access it directly. What I do is get a reference to the outer span using the ID, then select the span elements contained within using getElementsByTagName. Now you have access to the inner span and can change the contents.

A function something like this should do the trick:

function change_label_content(label_id,content) {
    try {
        var base_element    = document.getElementById(label_id);
        var span_collection = base_element.getElementsByTagName('span');
        span_collection[0].innerHTML = content;
    } catch(e) {

    }
}

Hope this helps.

Magnus,

For your information, this has been a common request from our customers and I'm happy to say that we will be enhancing the label field in the SR2 release in order to enable process designers to display dynamic values. SR2 is targeted for mid to late August.
