Transitioning from ajax to utilizing fade effects for smooth and seamless UI interaction

Transitioning from ajax to utilizing fade effects for smooth and seamless UI interaction

Currently, I am successfully using javascript and ajax to load content onto my div. However, the transition is quite static and not visually appealing.

I am aiming to incorporate a fading effect where the previous tab fades out when a new one is clicked, and the new tab fades in.

The syntax I have come across for achieving this effect is

$(selector).fadeIn(speed,callback)

. My dilemma lies in determining where exactly to implement this code since most sources suggest adding it after the click function, which my code does not have.

    var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
    var loadedobjects=""
    var rootdomain="http://"+window.location.hostname
    var bustcacheparameter=""

    function ajaxpage(url, containerid){
    var page_request = false
    document.getElementById(containerid).style.display = 'none';
    if (window.XMLHttpRequest) // if Mozilla, Safari etc
    page_request = new XMLHttpRequest()
    else if (window.ActiveXObject){ // if IE
    try {
    page_request = new ActiveXObject("Msxml2.XMLHTTP")
    } 
    catch (e){
    try{
    page_request = new ActiveXObject("Microsoft.XMLHTTP")
    }
    catch (e){}
    }
    }
    else
    return false
    page_request.onreadystatechange=function(){
    loadpage(page_request, containerid)
    }
    if (bustcachevar) //if bust caching of external page
    bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
    page_request.open('GET', url+bustcacheparameter, true)
    page_request.send(null)
    }

    function loadpage(page_request, containerid){
        if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1)) {
            document.getElementById(containerid).innerHTML=page_request.responseText;
            document.getElementById(containerid).style.display = 'block';
        }
    }


    function loadobjs(){
    if (!document.getElementById)
    return
    for (i=0; i<arguments.length; i++){
    var file=arguments[i]
    var fileref=""
    if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding
    if (file.indexOf(".js")!=-1){ //If object is a js file
    fileref=document.createElement('script')
    fileref.setAttribute("type","text/javascript");
    fileref.setAttribute("src", file);
    }
    else if (file.indexOf(".css")!=-1){ //If object is a css file
    fileref=document.createElement("link")
    fileref.setAttribute("rel", "stylesheet");
    fileref.setAttribute("type", "text/css");
    fileref.setAttribute("href", file);
    }
    }
    if (fileref!=""){
    document.getElementsByTagName("head").item(0).appendChild(fileref)
    loadedobjects+=file+" " //Remember this object as being already added to page
    }
    }
    }

Answer №1

When working with AJAX code, I recommend utilizing JQuery to streamline the process. JQuery offers built-in features for implementing fade in and out effects.

For instance, consider the following sample function:

function ajaxpage(url, containerid){
   $.get(url, function(response) {
      $('#'+containerid).fadeOut('slow', function() { 
         $('#'+containerid).html($.trim(response));
         $('#'+containerid).fadeIn('slow'); 
      });
   });
}

The function(response){} segment signifies the callback function for the AJAX GET request. Inside the $('#'+containerid).fadeOut() method, the enclosed function executes after the fade-out effect completes, triggering the subsequent fadeIn().

By organizing the fade-out, content replacement, and fade-in operations within callbacks, the sequence of events unfolds smoothly and coherent.

When creating a JavaScript animation, I recommend incorporating jQuery for a smooth result. However, if you are okay with sacrificing support for older browsers, you can opt for CSS3 as an alternative.

To achieve the desired effect of hiding/showing elements with a fade transition, apply the following CSS to the elements:

-o-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-webkit-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;

By changing CSS properties such as display from block to none, you can create a fading effect.

Note: To hide and show elements in JavaScript:

// Place this code within your click event handler or ajax callback function
document.getElementById(containerid).style.display = 'none';

// Call this function upon successful loading of content
function loadpage(page_request, containerid){
    if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1)) {
        document.getElementById(containerid).innerHTML=page_request.responseText;
        document.getElementById(containerid).style.display = 'block';
    }
}

Fade in functionality is dependent on using a jQuery object.

var ele = document.querySelector('div');
ele.fadeIn(); // This will not work
$(ele).fadeIn(); // This will work

If you have a raw DOM object (no jQuery), simply pass it through the $ function to enable fadeIn.

Additional Note

It is important to note that fadeIn does not necessarily have to be enclosed within a click function; this is just a demonstration. It can be executed in various parts of your code.
