Usage

Binding links

You can convert all links to Bjax links using bindLinks with a selector.

bindLinks('a')

Or you can bind on data-bjax selector.

bindLinks('[data-bjax]')

Loading part of a page

You can specify source and target using data attributes:

<a href="/" data-bjax data-source="#source" data-target="#target">My link</a>

Or you can specify that information when binding:

bindLinks('data-bjax', {
    source: '#source',
    target: '#target'
})

Also, you can use data-selector attribute or selector parameter to specify both target & source with one parameter.

Manually loading

You can load link manually using loadLink function.

loadLink('https://my.page/second-page', {
    target: '#part'
})

This will download whole page and insert it into element with part ID.

Bind manually

Using liveBind and loadLink you can customize bindings as much as you wish.

liveBind('[data-bjax]', 'click', function(event, element) {
    event.preventDefault()
    if (element instanceof HTMLAnchorElement) {
        loadLink(element.href, {
            selector: '#container'
        })
    }
})

Functions

loadLink(url, [options])

Downloads page from url and updates current page using downloaded HTML.

loadLink('https://my.page/second-page')

Options:

• target - DOM selector where should be inserted downloaded page HTML (default is body).
• source - DOM selected which indicates which part from downloaded page should be extracted (default is body).
• selector - Overwrites both target and source (default: undefined).
• shouldUpdateUrl - indicates if the url should be updated using url parameter using pushState (default is true).
• loader - custom loader instance (default is empty loader - {}).
• successCallback - callback which is called if the function finished the work without an error.
• errorCallback - Callback which is called if the function had an error and failed to finish.

bindLinks(selector, [options])

Binds loadLink funtion on given selector using liveBind.

bindLinks('a[data-bjax]')

Supports all loadLink options.

Additional options:

• url - target page URL, default is undefined and urlAttribute parameter is used.
• urlAttribute - url parameter value, which is taken from clicked element (default is href).
• targetAttribute - target parameter value, which is taken from clicked element (default is data-target).
• sourceAttribute - source parameter value, which is taken from clicked element (default is data-source).
• selectorAttribute - selector parameter value, which is taken from clicked element (default is data-selector).

liveBind(target, eventName, callback)

Listens eventName events on window object. Because it binds on window object, you can change inner DOM and it won't effect this bind at all.
