updated the jscrollpane to the latest version which support jquery 1.8 ! https://github.com/vitch/jScrollPane/blob/master/script/jquery.jscrollpane.min.js
I'm trying to refresh a div with content for a certain period. It will fire an Ajax GET call to a php script which render the content. For the first time ajax GET called, the ScrollPane is there, but for the second time Ajax GET(refresh) JScrollPane disappeared. Any how to reinitialize the jscrollpane?
function getActivity(callback)
{
$.ajax({
url: '../../views/main/activity.php',
type: 'GET',
complete: function(){
$('#activityLineHolder').jScrollPane({
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12
//autoReinitialize = true
});
},
success: function(data) {
var api = $('#activityLineHolder').jScrollPane(
{
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12
}
).data('jsp');
api.getContentPane().html(data);
api.reinitialise();
}
});
setTimeout(callback,10000);
}
$(document).ready(function(){
(function getActivitysTimeoutFunction(){
getActivity(getActivitysTimeoutFunction);
})();
});
Right now, my scrollpane is there after every Ajax call, but it shows buggy, the jscrollpane will keep moving left after every Ajax Call and slowly, it will hide the content. How is this happened?
foreach ($list as $notification) {
echo "<div class='feeds' id='$notification->notification_id'>";
$userObj = $user->show($notification->added_by);
echo $userObj->first_name.":<span class='text'>".$notification->activity."</span>";
echo " <span class='time'>".$notification_obj->nicetime($notification->created_at)."</span>";
echo "</div>";
}
something like this , that is my activity.php
here is my screenshot , anyone pls do help me @_@ http://img31.imageshack.us/img31/6871/jscrollpane.png
change the order of your commands. make a global variable that caches the ID like this:
var $activity, $activity_pane; // outside the dom ready
function getActivity(callback){
$.ajax({
url: '../../views/main/activity.php',
type: 'GET',
success: function(data) {
$activity_pane.html(data);
}
});
setTimeout(callback,10000);
}
$(function(){
$activity = $('#activityLineHolder');
$activity.jScrollPane({
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12
autoReinitialise: true
});
$activity_pane = $activity.data('jsp').getContentPane();
(function getActivitysTimeoutFunction(){
getActivity(getActivitysTimeoutFunction);
})();
});
My understanding is that a callback should be executed when the code within your method completes. If you are then wanting to run the getActivity() method again, shouldn't that be used in setTimeout(). Something like this:
function getActivity(callback)
{
$.ajax({
url: '../../views/main/activity.php',
type: 'GET',
complete: function(){
$('#activityLineHolder').jScrollPane({
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12
//autoReinitialize = true
});
},
success: function(data) {
$('#activityLineHolder').html(data);
}
});
setTimeout(function(){getActivity(callback);},10000);
if($.isFunction(callback)) {
callback();
}
}
I just take a look at http://jscrollpane.kelvinluck.com/ajax.html I had tried and works. i change setTimeout into setInterval (function from scrollpane). you can try this (i had tested)
$(document).ready(function(){
var api = $('#activityLineHolder').jScrollPane(
{
showArrows:true,
maintainPosition: false,
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12,
autoReinitialise: true
}
).data('jsp');
setInterval(
function()
{
$.ajax({
url: '../../views/main/activity.php',
success: function(data) {
api.getContentPane().html(data);
}
});
},
10000
);
});
I've faced this problem before, here is a snippet so you can get the idea. Good luck!
attachScroll = function(){
return $('.scroll-pane').jScrollPane({
verticalDragMinHeight: 17,
verticalDragMaxHeight: 17,
showArrows: true,
maintainPosition: false
});
}; // in this var I store all settings related to jScrollPane
var api = attachScroll().data('jsp');
$ajaxObj = $.ajax({
type: "GET", //set get or post
url: YOUR_URL,
data: null,
cache: false, //make sure you get fresh data
async: false, //very important!
beforeSend: function(){
},
success: function(){
},
complete: function(){
}
}).responseText; //$ajaxObj get the data from Ajax and store it
api.getContentPane().html($ajaxObj); //insert $ajaxObj data into "api" pane previously defined.
api.reinitialise(); //redraw jScrollPane
You can define the ajax call as a function and put it into a setInterval.
An example from official docs can be found here
Hope it helps!
Well I suppose that your HTML content coming from AJAX is long and you have problem with decreasing area size because it takes some time to render content by .html():
api.getContentPane().html(data);
And when it goes to the next line api.reinitialise() - HTML rendering isn't complete yet, but jScrollPane already catches current DIV width / height, initializes by those width / height, and then remaining html content is being inserted - and it appears outside of jScrollPane boundaries.
Read similar question: Wait for jquery .html method to finish rendering
So my adice:
1) Add a DIV at the end of your PHP code which will mark end of HTML coming from Ajax:
foreach ($list as $notification) {
...
}
echo '<div id="end-of-ajax"></div>';
2) Add periodical (200ms) check for "end-of-ajax" in your JS code - when it finds the end is reached, it calls for api.reinitialise():
var timer = setInterval(function(){
if ($("#activityLineHolder").find('#end-of-ajax').length) {
api.reinitialise();
clearInterval(timer);
}
}, 200);
EDIT
This is full JavaScript code:
function getActivity()
{
$.ajax({
url: '../../views/main/activity.php',
type: 'GET',
complete: function(){
$('#activityLineHolder').jScrollPane({
verticalDragMinHeight: 12,
verticalDragMaxHeight: 12
//autoReinitialize = true
});
},
success: function(data) {
var api = $('#activityLineHolder').jScrollPane(
{verticalDragMinHeight: 12,verticalDragMaxHeight: 12}
).data('jsp');
api.getContentPane().html(data);
var timer = setInterval(function(){
if ($("#activityLineHolder").find('#end-of-ajax').length) {
api.reinitialise();
clearInterval(timer);
}
}, 200);
}
});
}
$(document).ready(function(){
setInterval(getActivity,10000);
});
Im not sure about what your content is but just make sure that you reset the widths and heights accordingly before reinitlizing. as i had the same issue, and that was the problem
var origHeight =$('#GnattChartContainerClip').height();
var GanttChart = $('#EntireGnattWrapper').get(0).GanttChart;
$('#GnattChartContainerClip').find('#PaddingGnatt').remove();
$('#HeadersCol').find('#PaddingHeaders').remove();
var pane = $('#GnattChartContainerClip');
$('#GnattChartContainerClip').height(origHeight+height);
$('#GnattChartContainerClip').append('<div id="PaddingGnatt" style="width:'+GanttChart.TotalWidth+'px;height:25px"></div>');
$('#HeadersCol').append('<div id="PaddingHeaders" class="header" style="height:25px"></div>');
var paned = pane.data('jsp');
paned.reinitialise();
