Public Methods

Public methods are for assets:

  • dhtml.getVar(name, undefined_fallback) - returns string value of a banner variable with name (flashvars) or provided default value if variable does not exist. Example how get clickTAG and landingPageTarget variables values from system if not present - use default:

    clickTAGvalue = dhtml.getVar('clickTAG', '');
    landingPageTarget = dhtml.getVar('landingPageTarget', '_blank');
  • dhtml.sendEvent(id, name, vars) - registers event in Adform system;
    If sending custom event id must be in range from 1 to 19.  name argument is required and vars object is optional.
    vars object example: { bv1: 'John', bv2: 'Malcolm' }

    button.onclick = function() {
                    var id = 1,
                    name = 'banner click',
                    eventVars = {
                        bv1: "John",
                        bv2: "Colin",
                        bv3: "24"
                dhtml.sendEvent(id, name, eventVars);
                return false;
  • dhtml.getAsset(id) - returns URL of an asset with the given id, or 'undefined' if that asset doesn't exist. 
    var url = dhtml.getAsset(1); //A call to the function with the asset id.
  • dhtml.inscreen - use this object to track banner in-screen parameters from asset.


    • on(type, callback) - add event listener.
    • once(type, callback) - add event listener, and remove after it fires.
    • off(type, callback) - remove event listener.


    • 'visible' - fires when banner visible parameter changes.
    • 'percent' - fires when banner percent parameter changes.
    • 'change' - fires when any banner parameter changes.

    Note: Every event (except 'change') passes value argument to its callback. This argument holds latest banner in-screen parameter value.


    • visible (Boolean) - holds value whenever banner is visible or not (true or false).
    • percent (Number) - holds banner visibility percent value (from 0 to 100).

    Code Examples:

        .on('visible', function (value) { console.log('visible change', value); })
        .on('percent', function (value) { console.log('percent change', value); })
        .on('change', function () {
          console.log('some change', {
            visible: this.visible,
            percent: this.percent
  • dhtml.external.
    • expand() – expand banner from asset (used in axpandable banner types)
    • close() – collapse or close floating banner
    • superClose() – close and destroy entire banner
    • initPoliteMode() – announce that asset is ready to load heavy content (used with dhtml.sharedEvents.on('pageLoadComplete', listener))
    • updateBox(x, y, width, height) – used by Adform.SingleExpanding
    • expandComplete() – used by Adform.SingleExpanding
    • collapseComplete() – used by Adform.SingleExpanding
    • initScroll() - Will be used by Adform.FilmStrip
    • initSingleExpanding(x, y) – used by Adform.SingleExpanding
    • toggleFullScreen(status) – used by Adform.VideoPlayer

These methods are for an interacting banner.

  • includeAPI() - method that loads Adform.DHTML.js file from appropriate Adform servers. All it does is just document writing the script, ex.:
doc.write('<script src="'+fv.staticDomain + 'scripts/rmb/Adform.DHTML.js?bv='+'"><\/script>');
