I have an html table like that :
time | time_diff
12:01|
12:21|
12:31|
how could I calculate time_diff using Javascript (with or without jQuery) so my table looks like :
time | time_diff
12:01| 20
12:21| 10
12:31|
I'm basically wondering how I can achieve multi lines operations on an html table?
Maybe something like this:
$('table tbody tr').each(function () {
var $row = $(this),
$nextRow = $row.next();
if ($nextRow.length) {
this.cells[1].innerHTML = timeDiff($nextRow.find('td').text(), $row.find('td').text());
}
});
function timeDiff(t1, t2) {
t1 = t1.split(':');
t2 = t2.split(':');
var diff = (t1[0] * 60 + +t1[1]) - (t2[0] * 60 + +t2[1]),
hours = Math.floor(diff / 60),
minutes = (diff - hours * 60) + '';
return hours + ':' + (minutes.length == 1 ? '0' + minutes : minutes);
}
Demo: http://jsfiddle.net/vJNa4/1/
Something like this...
function set(i, val) { sets value of seconds column, row i }
function get(i) {returns time from first column, row i;}
function diff(time1, time2) { returns difference }
last = '';
for(i=0,i<rows;i++){
if(i>0) set(i-1, diff(get(i), last));
last = get(i);
}
Sample implementation:
function set(i, val) {
$('table tr:eq('+(i+1)+' td:eq(2))').text(val);
}
function get(i) {
return $('table tr:eq('+(i+1)+' td:eq(1))').text();
}
function diff(time1, time2) {
var s1 = time1.split(':');
var s2 = time2.split(':');
return s1[0]*60+s1[1] - (s2[0]*60+s2[1]);
}

I have to put these two scripts in a single tag without them coming into conflict but I can not make it. Please, how can I do it?
Also is it better to insert multiple scripts in the same tag?
Script 1
var sec = 04;
var hour = 00;
var time0, time1;
var delay=0;
var duringtime = 1000;
time1 = (hour *10000 + min * 100 + parseInt(sec)).toString();
console.log("time1", time1);
function refresh() {
........
}
}
refresh();
Script 2
var min = 80;
var max = 85;
var random = Math.floor(Math.random() * (max - min)) + min;
if (localStorage.getItem("stockcount_99")) {
if (localStorage.getItem("stockcount_99") >= duration) {
var value = random;
} else {
var value = localStorage.getItem("stockcount_99");
}
} else {
var value = random;
}
document.getElementById('divCounter').innerHTML = value;
var stockcount_99 = function() {
if (value <= stopValue) { // end count down. <= or >=
clearInterval(interval);
value = stopValue;
} else {
value = parseInt(value) - 1; // + 1 or - 1
localStorage.setItem("stockcount_99", value);
}
document.getElementById('divCounter').innerHTML = value;
};
var interval = setInterval(function() {
stockcount_99();
}, speedcontrol);
With the following method can I isolate the two scripts and thus prevent any conflicts?
(function() {
...script 1...
})()
(function() {
...script 2...
})()
This is my Javascript code to increment in minutes in interval 1
fillMinutes = function () {
var table = widget.find('.timepicker-minutes table'),
currentMinute = viewDate.clone().startOf('h'),
html = [],
row = $('<tr>'),
step = options.stepping === 1 ? 5 : options.stepping;
while (viewDate.isSame(currentMinute, 'h')) {
if (currentMinute.minute() % (step * 4) === 0) {
row = $('<tr>');
html.push(row);
}
row.append('<td data-action="selectMinute" class="minute' + (!isValid(currentMinute, 'm') ? ' disabled' : '') + '">' + currentMinute.format('mm') + '</td>');
currentMinute.add(step, 'm');
}
table.empty().append(html);
}
I want to modify this to increment in 15 minutes interval.
Can someone help me on this.
The option for stepping is what I believe you want, like this:
<script type="text/javascript">
$(function () {
$('#yourTimePickerElement').datetimepicker({
stepping: 15
});
});
</script>
Here is the documentation for stepping:
stepping
Default: 1
Number of minutes the up/down arrow's will move the minutes value in the time picker
Bootstrap 3 Datepicker documentation
incrementMinutes: function () {
var newDate = date.clone().add(15, 'm');
if (isValid(newDate, 'm')) {
setValue(newDate);
}
}
decrementMinutes: function () {
var newDate = date.clone().subtract(15, 'm');
if (isValid(newDate, 'm')) {
setValue(newDate);
}
}
I am dealing with the following puzzle and I cannot understand why it is happening.
I have the following [I believe to be] equivalent pieces of javascript code, but one does not work as expected (notice the Console.Log):
Updates the UI a single time, then unexpectantly stops updating : http://jsfiddle.net/silentwarrior/1m0v6oj1/
jQuery(function () {
var isWorking = true;
if (isWorking) {
var timeEnd = 1431220406000; // generated from php
var timeNow = 1431210557000; // generated from php
var counter = 1;
var t = "";
setInterval(function () {
try {
var c = timeEnd - timeNow - counter;
console.log(c);
var d = new Date(c);
if (c <= 1) {
window.location.href = window.location.href;
return;
}
t = "";
if (d.getHours() > 0) {
t += d.getHours() + "h ";
}
if (d.getMinutes() > 0) {
t += d.getMinutes() + "m ";
}
t += d.getSeconds();
jQuery("#factory_start_prod").val("Working ... " + t + "s left");
counter = counter + 1;
} catch (e) {
}
}, 1000);
}
});
Updates the UI constantly as expected: http://jsfiddle.net/silentwarrior/n3gkum2e/
jQuery(function () {
var isWorking = true;
if (isWorking) {
var timeEnd = 1431220406000;
var timeNow = 1431210557000;
var counter = 1;
var t = "";
setInterval(function () {
try {
var c = timeEnd - Date.now();
console.log(c);
var d = new Date(c);
if (c <= 1) {
window.location.href = window.location.href;
return;
}
t = "";
if (d.getHours() > 0) {
t += d.getHours() + "h ";
}
if (d.getMinutes() > 0) {
t += d.getMinutes() + "m ";
}
t += d.getSeconds();
jQuery("#factory_start_prod").val("Working ... " + t + "s left");
counter = counter + 1;
} catch (e) {
}
}, 1000);
}
});
The only difference from each other is that, the one that works uses Date.now() to get the current timestamp, while the other one uses a pre-built time stamp.
Why would one example update the text in the input correctly while the other wouldn't?
PS: it is important to me to use generated timestamps instead of Date.now() in order to not depend on the users system when calculating the time left.
Your first example is working, however with each iteration you are only subtracting 1 from the timestamp value, which is equivalent to 1ms. Hence the value never appears to change unless you wait a really long time. You need to increment the counter by 1000 on each iteration for a second to be counted:
counter = counter + 1000;

In my project, users can add timecode in and out points for their project, and the project automatically figures out the total duration of the timecode. But I want to add a function that will take all the available timecode durations, convert them to seconds, add them together, then convert the final number back to timecode and put it in a text input.
This is my code, but I keep getting syntax errors:
function timeToSeconds(t) {
var tc = t.split(':');
return parseInt(tc[0])*3600 + parseInt(tc[1])*60 + parseInt(tc[2]);
}
function tcDuration(tcin, tcout) {
function z(n){return (n<10?'0':'') + n;}
var duration = timeToSeconds(tcout) - timeToSeconds(tcin);
var hoursmins = Math.floor(duration / 60);
return z(Math.floor(hoursmins/60)) + ':' + z(hoursmins % 60) + ':' + z(duration % 60);
}
// Run this function every time a film_tc_out cell is changed
function film_tc_Duration() {
if (document.getElementById("film_tc_in").value == '') {var film_tc_in = '00:00:00';} else { var film_tc_in = document.getElementById("film_tc_in").value;}
if (document.getElementById("film_tc_out").value == '') {var film_tc_out = '00:00:00';} else { var film_tc_out = document.getElementById("film_tc_out").value;}
document.getElementById("film_tc_duration").value = tcDuration(film_tc_in, film_tc_out);
}
// Run this function every time a src_tc_out cell is changed
function src_tc_Duration() {
if (document.getElementById("src_tc_in").value == '') {var src_tc_in = '00:00:00';} else { var src_tc_in = document.getElementById("src_tc_in").value;}
if (document.getElementById("src_tc_out").value == '') {var src_tc_out = '00:00:00';} else { var src_tc_out = document.getElementById("src_tc_out").value;}
document.getElementById("src_tc_duration").value = tcDuration(src_tc_in, src_tc_out);
}
// Run this function every time a src_wd_out cell is changed
function src_wd_Duration() {
if (document.getElementById("src_wd_in").value == '') {var src_wd_in = '00:00:00';} else { var src_wd_in = document.getElementById("src_wd_in").value;}
if (document.getElementById("src_wd_out").value == '') {var src_wd_out = '00:00:00';} else { var src_wd_out = document.getElementById("src_wd_out").value;}
document.getElementById("src_wd_duration").value = tcDuration(src_wd_in, src_wd_out);
}
function total_tc_Duration() {
var val = document.getElementsByClassName('.asset_src_tc_duration');
var total_tc = 0;
var v;
for (var i = 0; i < val.length; i++) {
v = timeToSeconds(val[i]);
if (!isNaN(v)) total_tc += v;
}
return (total_tc);
}
function updateAssetTimecode() {
document.getElementById("timecode_total").value = total_tc_Duration();
}
Update: I've rewritten the For Loop to see if that helps - it currently gives me an answer now, although the answer is always "0". It's not spitting out any errors but it seems to think the variable val isn't a number?
Your tcDuration function won't work like you expect. You don't subtract the already calculated hours before doing the minutes calculation and the same with seconds.
function tcDuration(tcin, tcout) {
function z(n){return (n<10?'0':'') + n;}
var duration = timeToSeconds(tcout) - timeToSeconds(tcin);
var hoursmins = Math.floor(duration / 60);
return z(Math.floor(hoursmins / 60)) + ":" + z(hoursmins % 60) + ":" + z(duration % 60);
}
I have this code:
var hour = parseInt(js_arr[j].substring(0, 1));
var min = parseInt(js_arr[j].substring(3, 4));
var seconds = parseInt(js_arr[j].substring(6, 7));
var mil_sec = parseInt(js_arr[j].substring(9, 11));
var time = (hour * 3600000) + (min * 60000) + (seconds * 1000) + mil_sec;
function timeout() {
setTimeout(function () {
if (true) {
document.getElementById('subs').innerHTML = js_arr[i];
i = i + 4;
j = j + 4;
hour = parseInt(js_arr[j].substring(0, 1));
min = parseInt(js_arr[j].substring(3, 4));
seconds = parseInt(js_arr[j].substring(6, 7));
mil_sec = parseInt(js_arr[j].substring(9, 11));
time = (hour * 3600000) + (min * 60000) + (seconds * 1000) + mil_sec;
timeout();
} else {
timeout();
}
}, time);
}
Before javascript code I have an onclick="timeout(); button.
This button allows subtitles to play. What I would also like it to do is to stop these subtitles from playing by clicking on that same button. It would be great if someone could help!
Thanks a lot.
Add a variable that indicates whether the timeout is active. In the timeout()-function, this variable is checked and another loop is only initiated when it is true. To Start and Stop you simply set (and call timeout()) or reset the variable.
var hour = parseInt(js_arr[j].substring(0,1));
var min = parseInt(js_arr[j].substring(3,4));
var seconds = parseInt(js_arr[j].substring(6,7));
var mil_sec = parseInt(js_arr[j].substring(9,11));
var time = (hour*3600000)+(min*60000)+(seconds*1000)+mil_sec;
var timeOutRunning = false;
function startTimeOut() {
timeOutRunning = true;
timeout();
}
function stopTimeOut() {
timeOutRunning = false;
}
function timeout() {
if(timeOutRunning) {
setTimeout(function() {
document.getElementById('subs').innerHTML = js_arr[i];
i=i+4;
j=j+4;
hour = parseInt(js_arr[j].substring(0,1));
min = parseInt(js_arr[j].substring(3,4));
seconds = parseInt(js_arr[j].substring(6,7));
mil_sec = parseInt(js_arr[j].substring(9,11));
time = (hour*3600000)+(min*60000)+(seconds*1000)+mil_sec;
timeout();
}, time);
}
}
And then the onclick-function:
onclick="if(timeOutRunning) { stopTimeOut(); } else { startTimeOut(); }"
