Properties

Here you can find properties specifically related to the Tabs container.

Name

If you are not familiar with the JavaScript framework, get started with the JavaScript basics.

Note

The container is only accessible once the form is rendered, so all calls to the containers must be inside fd.rendered event:

fd.rendered(function(){
    //hide the container
    fd.container('Container1').hidden = true;
    //show the container
    fd.container('Container1').hidden = false;
});

Get HTML element

Access HTML element inside the container.

//access container's HTML
var htmlcontainer = fd.container('Container1').$el;

Hide container

Hide a container from a user.

//hide container
fd.container('Container1').hidden = true;

//show container
fd.container('Container1').hidden = false;

Tabs

The property holds tabs of the container as an array of objects. Can be used to get tabs and their properties.

fd.container('Container1').tabs

Detect tab change

Execute a function when a user switches between tabs:

fd.container('Container1').$watch('currentTab', function(newIndex, prevIndex) {
    alert('Previous tab: ' + prevIndex);
    alert('Current tab: ' + newIndex);
});

Disable tab

Disable or enable a tab:

//disable the second tab
fd.container('Container1').tabs[1].disabled = true;

//enable the second tab
fd.container('Container1').tabs[1].disabled = false;

Hide tab

Hide or show a tab dynamically using a combination of JavaScript code and CSS.

Disable the tab:

//disable the second tab
fd.container('Container1').tabs[1].disabled = true;

//enable the second tab
fd.container('Container1').tabs[1].disabled = false;

Add CSS styling to hide the disabled tab:

.fd-form .tabset .disabled{
    display: none; /* hide disabled tabs */
}

/* set the second tab background */
.fd-form .tabset li:nth-child(2) a {
        background-color: crimson !important;

}

/* set the second tab background when it is opened */
