MEMBUAT WIDGET BACK TO TOP

kali ini saya akan share cara mudah membuat widget back to top tanpa harus mengedit HTML. tombol back to top di gunakan agar mempermudah pembaca blog untuk melihat kembali artikel di atas yang  terkadang artikelnya terlalu panjang, untuk demo lihat pada bagian kanan bawah yang ada di blog ini.

pertama-tama login dulu yah ke akun blogger kalian masing-masing. lalu tambahkan widget HTML/JavaScript lalu masukan kode di bawah ini :

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>

<script type="text/javascript" >

var scrolltotop={

//startline: Integer. Number of pixels from top of doc scrollbar is scrolled before showing control

//scrollto: Keyword (Integer, or "Scroll_to_Element_ID"). How far to scroll document up when control is clicked on (0=top).

setting: {startline:100, scrollto: 0, scrollduration:1000, fadeduration:[500, 100]},

controlHTML: '<img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjWQj2Ag4V7x9pUoWifoFSmqynncAeJT-5vavUfq1mHcXKjwq_EPViWME5WVUq3QJRP4jXqU_6_IRqGt62VDMfPEQYbXaolEU1wpC0PdSWEtrw2Frmt-VItNXvm3HYyP8Gz7olAIxvmAd0/h120/top+%252849+x+49%2529.png" />', //HTML for control, which is auto wrapped in DIV w/ ID="topcontrol"

controlattrs: {offsetx:10, offsety:10}, //jarak ke kanan / bawah

anchorkeyword: '#top', //Enter href value of HTML anchors on the page that should also act as "Scroll Up" links

state: {isvisible:false, shouldvisible:false},

scrollup:function(){

if (!this.cssfixedsupport) //if control is positioned using JavaScript

this.$control.css({opacity:0}) //hide control immediately after clicking it

var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto)

if (typeof dest=="string" && jQuery('#'+dest).length==1) //check element set by string exists

dest=jQuery('#'+dest).offset().top

else

dest=0

this.$body.animate({scrollTop: dest}, this.setting.scrollduration);

},

keepfixed:function(){

var $window=jQuery(window)

var controlx=$window.scrollLeft() + $window.width() - this.$control.width() - this.controlattrs.offsetx

var controly=$window.scrollTop() + $window.height() - this.$control.height() - this.controlattrs.offsety

this.$control.css({left:controlx+'px', top:controly+'px'})

},

togglecontrol:function(){

var scrolltop=jQuery(window).scrollTop()

if (!this.cssfixedsupport)

this.keepfixed()

this.state.shouldvisible=(scrolltop>=this.setting.startline)? true : false

if (this.state.shouldvisible && !this.state.isvisible){

this.$control.stop().animate({opacity:1}, this.setting.fadeduration[0])

this.state.isvisible=true

}

else if (this.state.shouldvisible==false && this.state.isvisible){

this.$control.stop().animate({opacity:0}, this.setting.fadeduration[1])

this.state.isvisible=false

}

},

init:function(){

jQuery(document).ready(function($){

var mainobj=scrolltotop

var iebrws=document.all

mainobj.cssfixedsupport=!iebrws || iebrws && document.compatMode=="CSS1Compat" && window.XMLHttpRequest //not IE or IE7+ browsers in standards mode

mainobj.$body=(window.opera)? (document.compatMode=="CSS1Compat"? $('html') : $('body')) : $('html,body')

mainobj.$control=$('<div id="topcontrol">'+mainobj.controlHTML+'</div>')

.css({position:mainobj.cssfixedsupport? 'fixed' : 'absolute', bottom:mainobj.controlattrs.offsety, right:mainobj.controlattrs.offsetx, opacity:0, cursor:'pointer'})

.attr({title:'Kembali ke Atas'})

.click(function(){mainobj.scrollup(); return false})

.appendTo('body')

if (document.all && !window.XMLHttpRequest && mainobj.$control.text()!='') //loose check for IE6 and below, plus whether control contains any text

mainobj.$control.css({width:mainobj.$control.width()}) //IE6- seems to require an explicit width on a DIV containing text

mainobj.togglecontrol()

$('a[href="' + mainobj.anchorkeyword +'"]').click(function(){

mainobj.scrollup()

return false

})

$(window).bind('scroll resize', function(e){

mainobj.togglecontrol()

})

})

}

}

scrolltotop.init()
