I have two blocks of code. They both work together to list and play MP3 files from my AWS S3 Container bucket. But I cannot figure out the path to the "Album Cover" (i.e. Poster). KEEP IN MIND, each album folder contains a poster image that is the same name as the folder with a jpg extension. For example, see below:
Folder name: Beatles-Greatest-Hits
Folder Contents:
song01.mp3
song02.mp3
song03.mp3
Beatles-Greatest-Hits.jpg
This blocks works fine connects to the bucket: II realize it is long, but I am trying the find the path to the poster, so I included it all.

Below is the code that formats the jplayer code. I am trying to get the "Poster" path. If I get it correct, then it will display properly...
bucket.listObjects(

Delimiter : '/'
},
function (err, data)
{
if(data.Contents.length)
{
var prefix = '<?php echo $_REQUEST['p']; ?>';
for(var countAws=1; countAws < data.Contents.length; countAws++)
{
var key = data.Contents[countAws].Key;
var fileName = key.replace(prefix, '');
var linkAws = getObject(key);
var newlinkAws = linkAws.split('?');
var links = newlinkAws[0];
console.log(links);
myPlaylist.add({
title:""+fileName+"",
artist:"Artist",
mp3:links,
oga:links,
poster: ""+currentFolder+"".jpg //<--- HERE IS THE ISSUE
});
}
}
}
)
******* The code "poster: ""+currentFolder+"".jpg" above is where the problem is.
The absolute link to the example I gave above would be:
AWSS3/musicpax/mpx_music/Beatles-Greatest-Hits/Beatles-Greatest-Hits.jpg
But since this is dynamic, I cant use an absolute link. Can you provide any insight from the code at the top - that will lead to the correct path configuration.
Thank you in advance for any help.
This pulled the name from the link (path)... where it says 'HERE'
for(var countAws=1; countAws < data.Contents.length; countAws++)
{
var key = data.Contents[countAws].Key;
var fileName = key.replace(prefix, '');
var linkAws = getObject(key);
var newlinkAws = linkAws.split('?');
var links = newlinkAws[0];
/* Gets Album name HERE */
var album = links;
album = album.split("/");
album_name = (album[4]);
console.log(links);
myPlaylist.add({
title:""+fileName+"",
artist:""+album_name+"",
mp3:links,

I was been trying to switch IDEs.
What if I will want to load MISRA check result file to Visual Studio.
Is there any direct or simpler way?
Made indirect workaround:
var fso = new ActiveXObject("Scripting.FileSystemObject");
var rootPath = fso.GetFolder(".");
var cStat = rootPath.files;
for(var objEnum = new Enumerator(cStat); !objEnum.atEnd(); objEnum.moveNext()) {
var strFileName = objEnum.item();
if (strFileName.ShortName.length - strFileName.ShortName.toUpperCase().indexOf(".TXT") != 4) continue;
//WScript.Echo(strFileName);
break;
}
var ts = strFileName.OpenAsTextStream(1);
while(!ts.AtEndOfStream) {
var textLine = ts.ReadLine();
textLine = textLine.split('\t'); // IAR MISRA line: Description Rule Severity File:Line
if (textLine[3])
{
var res = textLine[3].replace(/(.+):(\d+)/g, "$1($2)");
if (textLine[2] == "Low")
{
res += ": warning " + textLine[1] + ": " + textLine[0];
}
else
{
res += ": error " + textLine[1] + ": " + textLine[0] + ' ' + textLine[2];
}
WScript.Echo(res);
}
}
ts.Close();
Using fake NMAKE project with build command like cscript /NoLogo PrintLog.js.
Now I can open files reported by MISRA in VS by copying export txt file to this project and running build.
Similar older IAR warning(s) filter used as pipe by command:
...\iarbuild "project.ewp" ReleaseCfg | cscript /NoLogo IARfilterPipe.js.
var fso = new ActiveXObject("Scripting.FileSystemObject");
var rootPath = fso.GetFolder(".") + '\\';
var x = oldBad(), skip = {};
for (i in x) skip[x[i]] = 1;
var stat = [0, 0], all = [], newWarnings = [];
do {
var line = WScript.StdIn.ReadLine();
if (line.indexOf('[') > 0) // possible warning line
{
all.push(line);
line = line.replace(rootPath, "");
var fit = 0;
if (line.indexOf("Remark[") > -1)
{
fit++;
stat[0]++;
line = line
.replace(/\d+>\s+/g, "")
.replace(/Remark\[(\S+)\]:/g, "Warning $1:");

if (m == null) // no name.ext
{

}
else if (m.length == 1) // single filename
{

}
}

{
all = all.sort();
writeFile("buildFiles.txt", all.join('\n'));

Can some body help me modify this script.
The purpose of the script is to change bids for the keywords based on average position. One of the assumptions that the script has is that it sets a firstpagebid for the keyword but it won't allow for the bid to go below the firstpagebid even if the position is too high.
Is there a way to remove this restriction? so basically if the new cpc calculated is lower than the first page bid then it allows for the new cpc to be lower than the firstpage bid.

As I understand, the script increases the cpcBid when the current average position is too high, and decreases it when the position is too low.
But when the bid is decreased and the previous bid is more than firstPageBid, the new bid will not decrease below firstPageBid.
Remove
if (cpcBid > firstPageBid) {
var newBid = Math.max(firstPageBid,newBid);
}
to allow your new bid to go lower than firstPageBid.

Now I want to get ( var tempStreamers = ) username from DATABASE.
You can get the tempStreamers by JSONP method which you need a new api to output the data.
Use setinterval to run you function every 2 seconds.Then you will get the newest data.
I have a JQuery plugin i am using as part of my project. The file is located in the root of my solution folder under a file called "jquery.tablePagination.js" I want to alter some of the parameters inside of the file without hard coding the data.
The script is as follows..
(function ($) {
$.fn.tablePagination = function (settings) {
var defaults = {
firstArrow: (new Image()).src = "./images/first.gif",
prevArrow: (new Image()).src = "./images/prev.gif",
lastArrow: (new Image()).src = "./images/last.gif",
nextArrow: (new Image()).src = "./images/next.gif",
rowsPerPage: 5,
currPage: 1,
optionsForRows: [5, 10],
ignoreRows: []
};
settings = $.extend(defaults, settings);
return this.each(function () {
var table = $(this)[0];
var totalPagesId = '#' + table.id + '+#tablePagination #tablePagination_totalPages';
var currPageId = '#' + table.id + '+#tablePagination #tablePagination_currPage';
var rowsPerPageId = '#' + table.id + '+#tablePagination #tablePagination_rowsPerPage';
var firstPageId = '#' + table.id + '+#tablePagination #tablePagination_firstPage';
var prevPageId = '#' + table.id + '+#tablePagination #tablePagination_prevPage';
var nextPageId = '#' + table.id + '+#tablePagination #tablePagination_nextPage';
var lastPageId = '#' + table.id + '+#tablePagination #tablePagination_lastPage';
var possibleTableRows = $.makeArray($('tbody tr', table));
var tableRows = $.grep(possibleTableRows, function (value, index) {
return ($.inArray(value, defaults.ignoreRows) == -1);
}, false)
var numRows = tableRows.length
var totalPages = resetTotalPages();
var currPageNumber = (defaults.currPage > totalPages) ? 1 : defaults.currPage;
if ($.inArray(defaults.rowsPerPage, defaults.optionsForRows) == -1)
defaults.optionsForRows.push(defaults.rowsPerPage);
function hideOtherPages(pageNum) {

return;
var startIndex = (pageNum - 1) * defaults.rowsPerPage;
var endIndex = (startIndex + defaults.rowsPerPage - 1);

for (var i = 0; i < tableRows.length; i++) {
if (i < startIndex || i > endIndex) {
$(tableRows[i]).hide()
}
}
}
function resetTotalPages() {
var preTotalPages = Math.round(numRows / defaults.rowsPerPage);
var totalPages = (preTotalPages * defaults.rowsPerPage < numRows) ? preTotalPages + 1 : preTotalPages;
if ($(totalPagesId).length > 0)
$(totalPagesId).html(totalPages);
return totalPages;
}

$(currPageId).val(currPageNumber)
}

optsPerPage.sort();
var perPageDropdown = $(rowsPerPageId)[0];
perPageDropdown.length = 0;
for (var i = 0; i < optsPerPage.length; i++) {
if (optsPerPage[i] == defaults.rowsPerPage) {
perPageDropdown.options[i] = new Option(optsPerPage[i], optsPerPage[i], true, true);
isRowsPerPageMatched = true;
}
else {
perPageDropdown.options[i] = new Option(optsPerPage[i], optsPerPage[i]);
}
}
if (!isRowsPerPageMatched) {
defaults.optionsForRows == optsPerPage[0];
}
}

$(firstPageId).bind('click', function (e) {

});
$(prevPageId).bind('click', function (e) {
resetCurrentPage(currPageNumber - 1)
});
$(nextPageId).bind('click', function (e) {
resetCurrentPage(currPageNumber + 1)

resetCurrentPage(totalPages)
});
$(currPageId).bind('change', function (e) {
resetCurrentPage(this.value)

I want to be able to alter the following settings: RowsPerPage and OptionforRows.
I have tried to copy and paste the code from the script directly into my .aspx file next to some other Jquery/JavaScript I already have however the plugin doesn't run when I do this.
Could it be possible to write to the settings part of the file from the code behind? It would also work if the file could read the settings from a certain hidden field but I can't get it to run on my .aspx to do this. I'm not sure how to go about solving this issue.
I have ended up solving this issue by first copying the script and pasting in my .aspx file. I was originally copying the code inside of the document ready function:
$(document).ready(function)
Once I have had this done It was quite easy to pass through a variable from the code behind to be used as the required setting.
rowsPerPage: <%=PageRowAmount%>,
For the code behind I have added the following:
Public PageRowAmount As Integer = 10
and in the page_load I have added
Page.DataBind()
Solved!
I posted a similar question at the Drupal Forum, but I haven't had much luck.
I'm upgrading a site from D6 to D7. So far it's gone well, but I'm getting a Javascript error that I just can't pin down a solution for.
This is a cut down version of the whole script:
(function($) {
function sign(secret, message) {
var messageBytes = str2binb(message);
var secretBytes = str2binb(secret);
if (secretBytes.length > 16) {
secretBytes = core_sha256(secretBytes, secret.length * chrsz);
}
var ipad = Array(16), opad = Array(16);
for (var i = 0; i < 16; i++) {
ipad[i] = secretBytes[i] ^ 0x36363636;
opad[i] = secretBytes[i] ^ 0x5C5C5C5C;
}
var imsg = ipad.concat(messageBytes);
var ihash = core_sha256(imsg, 512 + message.length * chrsz);
var omsg = opad.concat(ihash);
var ohash = core_sha256(omsg, 512 + 256);
var b64hash = binb2b64(ohash);
var urlhash = encodeURIComponent(b64hash);
return urlhash;
}
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
Date.prototype.toISODate =
new Function("with (this)\nreturn " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
function getNowTimeStamp() {
var time = new Date();
var gmtTime = new Date(time.getTime() + (time.getTimezoneOffset() * 60000));
return gmtTime.toISODate() ;
}
}(jQuery));
The part that keeps throwing an error I'm seeing in Firebug is at:
Date.prototype.toISODate =
new Function("with (this)\n return " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
Firebug keeps stopping at "addZero is not defined". JS has never been my strong point, and I know some changes have been made in D7. I've already wrapped the entire script in "(function($) { }(jQuery));", but I must be missing something else. The same script works perfectly on the D6 site.
Here is the "fixed" version of the whole code with #Pointy suggestion added. All I left out is the part of the script for making the hash that goes to Amazon, and some of my declared variables.

Here's a better version of your code:
Date.prototype.toISODate = function() {
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
var d = this;
return d.getFullYear() + '-' +
addZero(d.getMonth() + 1) + '-' +
addZero(d.getDate()) + 'T' +
addZero(d.getHours()) + ':' +
addZero(d.getMinutes()) + ':' +
addZero(d.getSeconds()) + '.000Z';
};
That moves "addDate" inside the extension function, and it avoids the horrid with statement.
