How to remove nth-1 array index in Javascript while doing Excel export

How do I remove Nth-1 rows from an array?
I am trying to export my records in Excel but am getting some html code in my Excel file. The reason for this is I am trying to remove that row but am not able to delete that particular row, because that row is dynamically changing.
I am getting data in an array while checking it in debug mode.
Can anyone help me with how I can remove total length of Array-1? For example, if I have 40 records then I want remove 39th position.
This is my JS Code:
[![$(function () {
var exportFlag = false;
var reportGrid = $(time.report.gridId);
if (reportGrid.length > 0) {
$(time.report.gridId).data("kendoGrid").bind("excelExport",
function(e) {
if (!exportFlag) {
var sheet = e.workbook.sheets\[0\];
var columns = e.sender.columns;
e.preventDefault();
exportFlag = true;
setTimeout(function() {
e.sender.saveAsExcel();
},
1000);
} else {
// e.sender.hideColumn(0);
//e.sender.hideColumn(e.sender.columns.length + 1);
exportFlag = false;
}
});
});][1]][1]
onExcelExport: function (e) {
setTimeout("location.reload(true);", 1000);
e.sender.hideColumn("OutIp");
e.sender.hideColumn("InIp");
var sheet = e.workbook.sheets[0];
var rows = sheet.rows;
var rowIdx, colIdx, cells, cell;
for (rowIdx = 0; rowIdx < rows.length; rowIdx++) {
if (rows[rowIdx].type === "data") {
cells = rows[rowIdx].cells;
var color = "#ffffff";
if (cells[0].value === true) {
color = "#ff0000";
}
for (colIdx = sheet.freezePane.colSplit; colIdx < cells.length; colIdx++) {
cell = cells[colIdx];
cell.background = color;
//cell.value = kendo.toString(cell.value, "c");
if (colIdx === 4) {
cell.value = cell.value.Hours + ":" + cell.value.Minutes;
}
else if (cell.value !== undefined && cell.value !== null && cell.value.Hours !== undefined) {
cell.value = utcTimeToLocalTime(cell.value.Hours + ":" + cell.value.Minutes);
}
else if (cell.value !== undefined && cell.value !== null && cell.value === true) {
cell.value = "Yes";
}
else if (cell.value !== undefined && cell.value !== null && cell.value === false) {
cell.value = "No";
}
}
}
}
},

To remove the last-but-one element of any array you could do:
var numberElements = yourArray.length;
var targetElement = numbElements - 1;
// second parameter is number of elements to remove
yourArray.splice(targetElement, 1);

How to use jQuery click not jumping to top of page

I'm using the following jQuery code for open my shop URL in a new tab windows when user click any part of page :
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
x = x.replace(/^\s+|\s+$/g, "");
if (x == c_name) {
return unescape(y);
}
}
}
function setCookie(c_name, value) {
var exdays = 1;
var exdate = new Date();
exdate.setHours(exdate.getHours() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}
function checkCookie() {
var username1 = getCookie("tabligh1");
var username2 = getCookie("tabligh2");
var usernam = "sendshod";
if (username1 == null | username2 == null) {
window.open('#', '_parent', 'toolbar=1,location=1,directories=1,status=1,menubar=1?,scrollbars=1,resizable=1');
window.focus();
}
if (username1 == "" | username1 == null) {
if (window.open('http://shop.url')) {
window.focus();
setCookie("tabligh1", usernam);
}
}
}
// document.onclick = checkCookie;
jQuery(document).click(function (event) {
if (!jQuery(event.target).is('.hamyar_area, .hamyar_area *')) {
checkCookie();
}
})
if ((window.XMLHttpRequest == undefined) && (ActiveXObject != undefined)) window.onload = checkCookie;
When user click in page , a # character add end of correct URL like this:
before click : domain.com
after click : domain.com/#
And when # character add to end of URL, page jumping to top of page.
I want to use this jquery code but I don't want when user click on the page, page don't jumping to the top.

Edit ajax loaded content

I have a HTML that loads a table from another page. I've got the CSS to work properly, but I can't edit the table using jQuery when it's pooled by the script, only when I have the table directly on the page. I'm guessing that maybe my changes are running before the load? I don't know..
I want to let you know that I'm not a programmer my self, but more of a curious person. I've searched around and found some things, but the lack of knowledge doesn't let me implement them. Hope you can help me.
The Script I use to read the data from the other page (p1.html)
<script type="text/javascript">
var TimerLoad, TimerChange;
var MaxNum, Rafraichir, Changement, ClassementReduit, ClassementReduitXpremier;

ClassementReduitXpremier = 10;
function Load(url, target) {
var xhr;
var fct;
if (UrlChange) url = UrlRefresh;
else UrlRefresh = url;
UrlChange = 0;
if (TimerLoad) clearTimeout(TimerLoad);
try {
xhr = new ActiveXObject("Msxml2.XMLHTTP")
} catch (e) {
try {
xhr = new ActiveXObject("Microsoft.XMLHTTP")
} catch (e2) {
try {
xhr = new XMLHttpRequest
} catch (e3) {
xhr = false
}
}
}
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200)
if (ClassementReduit == 0) document.getElementById(target).innerHTML = xhr.responseText;
else document.getElementById(target).innerHTML = ExtraireClassementReduit(xhr.responseText)

Loading the table into the body
$(document).ready(Load('p1.html', 'result'));
The code I need to run after (it works with the table directly on page or even on a button, but I can't get to work on page load)
function show_hide_column(col_id, do_show) {
var stl;
if (do_show) stl = 'block'
else stl = 'none';
var tbl = document.getElementsByTagName('table')[0];
var index = document.getElementById(col_id).cellIndex;
var rows = tbl.getElementsByTagName('tr');
for (var row = 0; row < rows.length; row++) {
var cels = rows[row].getElementsByTagName('td')
cels[index].style.display = stl;
}
}
function hide() {
show_hide_column("Id_Position", false);
show_hide_column("Id_Equipe", false);
show_hide_column("Id_Vehicule", false);
}

I fired a console.log() message for every stage of the previous code, to know when exactly the table was added to the page, to then hide the columns. Got it to work.

Making my javaScript popup to appear only once

I am creating a JavaScript popup. The code is as below.
The HTML:
<div id="ac-wrapper" style='display:none' onClick="hideNow(event)">
<div id="popup">
<center>
<h2>Popup Content Here</h2>
<input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
</center>
</div>
</div>
The CSS:
#ac-wrapper {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: url("images/pop-bg.png") repeat top left transparent;
z-index: 1001;
}
#popup {
background: none repeat scroll 0 0 #FFFFFF;
border-radius: 18px;
-moz-border-radius: 18px;
-webkit-border-radius: 18px;
height: 361px;
margin: 5% auto;
position: relative;
width: 597px;
}
The Script:
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
The jsFiddle Link:
http://jsfiddle.net/K9qL4/2/
The Issue:
The above script works fine, but I need to make the popUp to appear only once on my page.
i.e, when the user closes the popup, it should not appear until the user restarts the browser or clears his cache/cookie.
I tried using the below cookie script, but it does not work for me.
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 1; // number of days the cookie should last
var page = "myPage.html";
var windowprops = "width=300,height=200,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=yes";
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) {
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function amt(){
var count = GetCookie('count')
if(count == null) {
SetCookie('count','1')
return 1
}
else {
var newcount = parseInt(count) + 1;
DeleteCookie('count')
SetCookie('count',newcount,exp)
return count
}
}
function getCookieVal(offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function checkCount() {
var count = GetCookie('count');
if (count == null) {
count=1;
SetCookie('count', count, exp);
window.open(page, "", windowprops);
}
else {
count++;
SetCookie('count', count, exp);
}
}
// End -->
</script>

I thing in this case is better to use localStorage instead cookie.
localStorage have a more intuitive interface and user cannot restrict
this feature to be used. I have changed your code.
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(localStorage.getItem("popupWasShown") == null) {
localStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
Here is working jsFiddle.

Best regards.

To not show this untill restart browser - use local storage
localStorage.setItem("setted",true);
localStorage.getItem("setted");
FIDDLE
To not show untill clear cache\cookie use cookies
document.cookie = "setted=true";
document.cookie.indexOf("setted=true")!=-1
FIDDLE

I've used local storage instead of cookie for the reason mentioned otherwise
however, I have added the comparison, and checked that you want to show it (also added a reset button for you to test easily)
fiddle is: http://jsfiddle.net/K9qL4/8/
function PopUp(hideOrshow) {
if (hideOrshow === 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(localStorage.getItem("popupWasShown") !== "1" && hideOrshow === 'show') {
document.getElementById('ac-wrapper').removeAttribute('style');
localStorage.setItem("popupWasShown", "1");
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 1000);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') {
document.getElementById('ac-wrapper').style.display = 'none';
localStorage.setItem("popupWasShown", "1");
}
}
document.getElementById("reset").onclick = function() {
localStorage.setItem("popupWasShown", "3");
}

We have slightly modified the code with session storage in order to load the popup whenever the page is loaded (several times per day or in a new window/tab):
else if(sessionStorage.getItem("popupWasShown") == null) {
sessionStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
Full code:
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(sessionStorage.getItem("popupWasShown") == null) {
sessionStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}

**CSS:**
<style>
#popup{
display:none;
}
</style>
**HTML:**
<div id="popup">
<center>
<h2>Popup Content Here</h2>
<input type="button" name="submit" value="Submit"/>
</center>
</div>
**JS:**
<script>
getCookie = function(data){
var dset = data + "=";
var c = document.cookie.split(';');
for(var i=0; i<c.length; i++){
var val = c[i];
while (val.charAt(0)==' ') val = val.substring(1, val.length);
if(val.indexOf(dset) == 0) return val.substring(dset.length, val.length)
}
return "";
}
if(getCookie("popupShow") != "yes"){
document.getElementById('popup').style.display = "block";
//set cookie
document.cookie = 'popupShow=yes; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'
}
</script>
Try this one it works on my end;

javascript form cookies - select only opening cookie for first 10 indexes

I have never used cookies before, so I am using a peice of code I am very unfamiliar with.
It was working all fine, until I noticed just now that for select boxes, it is not working for any values after the tenth index. (for index 10 and above).
I have looked at the cookie stored on my system, and it appears t be saving them correctly. (I saw select10) ETC stored properly.
When it runs onload of body however, it is not loading in the values properly.
Here is the cookie code I am using:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 100;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1) { endstr = document.cookie.length; }
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg) return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
// use the following code to call it:
// <body onLoad="cookieForms('open', 'form_1', 'form_2', 'form_n')" onUnLoad="cookieForms('save', 'form_1', 'form_2', 'form_n')">
function cookieForms() {
var mode = cookieForms.arguments[0];
for(f=1; f<cookieForms.arguments.length; f++) {
formName = cookieForms.arguments[f];
if(mode == 'open') {
cookieValue = GetCookie('saved_'+formName);
if(cookieValue != null) {
var cookieArray = cookieValue.split('#cf#');
if(cookieArray.length == document[formName].elements.length) {
for(i=0; i<document[formName].elements.length; i++) {
if(cookieArray[i].substring(0,6) == 'select') { document[formName].elements[i].options.selectedIndex = cookieArray[i].substring(7, cookieArray[i].length-1); }
else if((cookieArray[i] == 'cbtrue') || (cookieArray[i] == 'rbtrue')) { document[formName].elements[i].checked = true; }
else if((cookieArray[i] == 'cbfalse') || (cookieArray[i] == 'rbfalse')) { document[formName].elements[i].checked = false; }
else { document[formName].elements[i].value = (cookieArray[i]) ? cookieArray[i] : ''; }
}
}
}
}
if(mode == 'save') {
cookieValue = '';
for(i=0; i<document[formName].elements.length; i++) {
fieldType = document[formName].elements[i].type;
if(fieldType == 'password') { passValue = ''; }
else if(fieldType == 'checkbox') { passValue = 'cb'+document[formName].elements[i].checked; }
else if(fieldType == 'radio') { passValue = 'rb'+document[formName].elements[i].checked; }
else if(fieldType == 'select-one') { passValue = 'select'+document[formName].elements[i].options.selectedIndex; }
else { passValue = document[formName].elements[i].value; }
cookieValue = cookieValue + passValue + '#cf#';
}
cookieValue = cookieValue.substring(0, cookieValue.length-4); // Remove last delimiter
SetCookie('saved_'+formName, cookieValue, exp);
}
}
}
// End -->
</script>
I beleive the problem lies with the following line, found about 3/4 of the way down the code block above (line 68):
if(cookieArray[i].substring(0,6) == 'select') { document[formName].elements[i].options.selectedIndex = cookieArray[i].substring(7, cookieArray[i].length-1); }
Just for reference, here is the opening body tag I am using:
<body style="text-align:center;" onload="cookieForms('open', 'ramsform', 'decksform', 'hullsform', 'crewform', 'shipwrightform'); Swap(crew0z,'crew0i'); Swap(crew1z,'crew1i'); Swap(crew2z,'crew2i'); Swap(crew3z,'crew3i'); Swap(crew4z,'crew4i'); Swap(crew5z,'crew5i'); Swap(crew6z,'crew6i'); Swap(crew7z,'crew7i'); Swap(crew8z,'crew8i'); Swap(crew9z,'crew9i');" onunload="cookieForms('save', 'ramsform', 'decksform', 'hullsform', 'crewform', 'shipwrightform');">
(Please ignore the swap()'s as they are unrelated)
Page I am working on can be found: http://webhostlet.com/POP.htm

In both the open and save codes, change:
document[formName].elements[i].options.selectedIndex
to:
document[formName].elements[i].selectedIndex
options is an array of all the options, the selectedIndex property belongs to the select element that contains them.
Change:
cookieArray[i].substring(7, cookieArray[i].length-1)
to:
cookieArray[i].substring(6)
You were off by 1 because you forgot that it's 0-based counting. The second argument isn't needed, it defaults to the rest of the string.
The reason it worked for the first 10 menu items is a quirk of substring: if the second argument is lower than the first, it swaps them! So "select5".substring(7, 6) is treated as "select5".substring(6, 7), which gets the last character of the string. But for the longer strings, it was `"select35".substring(7, 7), which is an empty string.
