Hello all,
i have too many log to show on timeline, so i decided to load only
logs around the center date. This work.
Now i want to load event as the user scroll on the line.
I put a on scroll event in the onload function
var b1=tl.getBand(1);
b1.addOnScrollListener(updateData());
And defined my function as :
function updateData() {
var eventSource = tl.getBand(1).getEventSource();
eventSource.clear();
var da = tl.getBand(1).getCenterVisibleDate();
var date = new Date(da);
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
Timeline.loadJSON("test.php?d="+day+"&m="+month
+"&y="+year, function(json, url) {
eventSource.loadJSON(json, url);
tl.finishedEventLoading();
});
tl.layout();
}
The problem i have is that he call infinitely the test.php page and
the script block.
What i missed?
All the js code (i just work on a "test page"):
var tl;
var eventSource = new Timeline.DefaultEventSource(0);
function onLoad() {
var theme1 = Timeline.ClassicTheme.create();
theme1.autoWidth = true;
theme1.mouseWheel = "default";
theme1.firstDayOfWeek=1;
var bandInfos = [
Timeline.createBandInfo({
overview: true,
width: "10%",
intervalUnit: Timeline.DateTime.MONTH,
eventSource: eventSource,
theme: theme1,
intervalPixels: 100,
timezone: 1
}),Timeline.createBandInfo({
width: "90%",
intervalUnit: Timeline.DateTime.DAY,
eventSource: eventSource,
theme: theme1,
intervalPixels: 300,
timezone: 1
})
];
bandInfos[0].syncWith = 1;
bandInfos[0].highlight = true;
tl = Timeline.create(document.getElementById("tl"),
bandInfos);
tl.getBand(1).setCenterVisibleDate(Timeline.DateTime.parseGregorianDateTime(new
Date()));
var da = tl.getBand(1).getCenterVisibleDate();
var date = new Date(da);
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
tl.loadJSON("test.php?d="+day+"&m="+month+"&y="+year,
function(json, url) {
eventSource.loadJSON(json, url);
tl.finishedEventLoading();
tl.getBand(1).setCenterVisibleDate(Timeline.DateTime.parseGregorianDateTime(new
Date()));
});
var b1=tl.getBand(1);
b1.addOnScrollListener(updateData());
}
function updateData() {
var eventSource = tl.getBand(1).getEventSource();
eventSource.clear();
var da = tl.getBand(1).getCenterVisibleDate();
//alert(da);
var date = new Date(da);
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
Timeline.loadJSON("test.php?d="+day+"&m="+month
+"&y="+year, function(json, url) {
eventSource.loadJSON(json, url);
//tl.finishedEventLoading();
});
tl.layout();
}
var resizeTimerID = null;
function onResize() {
if (resizeTimerID == null) {
resizeTimerID = window.setTimeout(function() {
resizeTimerID = null;
tl.layout();
}, 500);
}
}
Thanks
