Sorting Image Issue
Greeting,
I am writing a code in dojo that compares the date column in grid for the sorting. below is the code :
function(a,b){
var a1=new Date(a);
var a2=new Date(b);
var x = dojo.date.locale.format(a1, {datePattern: "yyyy-MM-dd", selector: "date"});
var y = dojo.date.locale.format(a2, {datePattern: "yyyy-MM-dd", selector: "date"});
if((a!=null)&&(b!=null)){
if (x.toLowerCase() < y.toLowerCase())
{
debugger;
return -1;
}
else if (x.toLowerCase() > y.toLowerCase())
{
debugger;
return 1;
}
else
{
debugger;
return 0;
}
}
Code works fine for me when the Language in the browser is English but when I changes to Dutch or any other then it doesnt sorts the values properly.
Please guide.
Thanks
I'm not sure why you're having this problem since those format calls ought to be returning the same result regardless, but that code seems severely overcomplicated.
If you are simply trying to sort dates in chronological order, you should merely need to compare them as numbers.
var a = [ '2015-10-18', '2015-10-12', '2015-10-16' ];
a.sort(function (a, b) {
a = new Date(a);
b = new Date(b);
if (a > b) {
return 1;
}
if (a < b) {
return -1;
}
return 0;
});
console.log(a); // ["2015-10-12", "2015-10-16", "2015-10-18"]

Is it possible to create a graph sorted in each time interval using Highcharts?
For expample, in this picture for January data will be in order: New York, Tokyo, London, Berlin. The same for each months - data should be shown decrease order
Highcharts doesn't have a built-in function to do that, but for example you can use the render event and organize columns, by changing their positions in the way you need.
events: {
render: function() {
var series = this.series,
longestSeries = series[0],
sortedPoints = [],
selectedPoints = [];
// find a series with the highest amount of points
series.forEach(function(s) {
if (s.points.length > longestSeries.points.length) {
longestSeries = s;
}
});
longestSeries.points.forEach(function(point) {
series.forEach(function(s) {
selectedPoints.push(s.points[point.index]);
});
sortedPoints = selectedPoints.slice().sort(function(a, b) {
return b.y - a.y;
});
selectedPoints.forEach(function(selectedPoint) {
if (
selectedPoints.indexOf(selectedPoint) !==
sortedPoints.indexOf(selectedPoint) &&
selectedPoint.graphic
) {
// change column position
selectedPoint.graphic.attr({
x: sortedPoints[selectedPoints.indexOf(selectedPoint)].shapeArgs.x
});
}
});
sortedPoints.length = 0;
selectedPoints.length = 0;
});
}
}

#ppotaczek Thank You for help a lot! I solve my issue, but i had to make some changes to your code:
events: {
render: function() {
if (this.series.length === 0) return
var series = this.series,
longestSeries = series[0],
sortedPoints = [],
selectedPoints = [];
// find a series with the highest amount of points
series.forEach(function(s) {
if (s.points.length > longestSeries.points.length) {
longestSeries = s;
}
});
longestSeries.points.forEach(function(point) {
series.forEach(function(s) {
selectedPoints.push(s.points[point.index]);
});
sortedPoints = selectedPoints.slice().sort(function(a, b) {
return b.y - a.y;
});
selectedPoints.forEach(function(selectedPoint) {
if (
selectedPoints.indexOf(selectedPoint) !==
sortedPoints.indexOf(selectedPoint) &&
selectedPoint.graphic
) {
// change column position
selectedPoint.graphic.attr({
x: selectedPoints[sortedPoints.indexOf(selectedPoint)].shapeArgs.x
});
}
});
sortedPoints.length = 0;
selectedPoints.length = 0;
});
}
},
}
So i changed:
// change column position
selectedPoint.graphic.attr({
x: sortedPoints[selectedPoints.indexOf(selectedPoint)].shapeArgs.x
});
to:
// change column position
selectedPoint.graphic.attr({
x: selectedPoints[sortedPoints.indexOf(selectedPoint)].shapeArgs.x
});
I'm trying to print qz tray from javascript.
I have barcode with number in ascending order 1,2,3,4, 5 and so on.
I looping the seq correctly . but when printed out, it was not in order.
setTimeout("directPrint2()",1000);
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
function directPrint2(){
var data;
var xhttp;
var v_carton = "' || x_str_carton ||'";
var carton_arr = v_carton.split('','');
var v1 = "' ||
replace(x_zebra_printer_id, '\', '|') ||
'".replace(/\|/g,"\\");
if(v1 == ""){
alert("Please setup ZPL Printer");
}
else{
xhttp=new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
data = [ toNative(this.responseText) ];
printZPL(data, v1);
}
};
for (var j = 0; j < carton_arr.length; j++){
var url = "' || x_wms_url ||
'WWW_URL.direct_print_label?in_carton_no="+toValidStr(carton_arr[j]);
xhttp.open("GET", url, false);
xhttp.send();
sleep(5000);
}
}
};
',
'javascript'
What's missing from your example:
I do not see any looping logic in the example calling the printZPL function,
printZPL isn't a QZ Tray function and you're missing the code snippet which it calls. Usually this would be qz.print(config, data);.
Regardless of the missing information, the qz.print(...) API is ES6/Promise/A+ based meaning if you want to call qz.print multiple times in a row you need to use a Promise-compatible technique. (e.g. .then(...) syntax) between your print calls as explained in the Chaining Requests guide.
To avoid this, you can concatenate all ZPL data into one large data array. Be careful not to spool too much data at once.
If you know exactly how many jobs you'll be appending, you can hard-code the promise chain:
qz.websocket.connect()
.then(function() {
return qz.printers.find("zebra"); // Pass the printer name into the next Promise
})
.then(function(printer) {
var config = qz.configs.create(printer); // Create a default config for the found printer
var data = ['^XA^FO50,50^ADN,36,20^FDRAW ZPL EXAMPLE^FS^XZ']; // Raw ZPL
return qz.print(config, data);
})
.catch(function(e) { console.error(e); });
Finally, if you do NOT know in advanced how many calls to qz.print(...) you can use a Promise loop as explained in the Promise Loop guide.
function promiseLoop() {
var data = [
"^XA\n^FO50,50^ADN,36,20^FDPRINT 1 ^FS\n^XZ\n",
"^XA\n^FO50,50^ADN,36,20^FDPRINT 2 ^FS\n^XZ\n",
"^XA\n^FO50,50^ADN,36,20^FDPRINT 3 ^FS\n^XZ\n",
"^XA\n^FO50,50^ADN,36,20^FDPRINT 4 ^FS\n^XZ\n"
];
var configs = [
{ "printer": "ZDesigner LP2844-Z" },
{ "printer": "ZDesigner LP2844-Z" },
{ "printer": "ZDesigner LP2844-Z" },
{ "printer": "ZDesigner LP2844-Z" }
];
var chain = [];
for(var i = 0; i < data.length; i++) {
(function(i_) {
//setup this chain link
var link = function() {
return qz.printers.find(configs[i_].printer).then(function(found) {
return qz.print(qz.configs.create(found), [data[i_]]);
});
};
chain.push(link);
})(i);
//closure ensures this promise's concept of `i` doesn't change
}
//can be .connect or `Promise.resolve()`, etc
var firstLink = new RSVP.Promise(function(r, e) { r(); });
var lastLink = null;
chain.reduce(function(sequence, link) {
lastLink = sequence.then(link);
return lastLink;
}, firstLink);
//this will be the very last link in the chain
lastLink.catch(function(err) {
console.error(err);
});
}
Note: The Promise Loop is no longer needed in QZ Tray 2.1. Instead, since 2.1, an array of config objects and data arrays can be provided instead.
I'm absolutely newbie in the Dojo, so my question may be too evident. Sorry.
I've programmatically created the complex menu, including MenuBar, based on the rows, selected from the DB.
All problems were solved besides one: the alignment of the final items and submenu items differ.How it looks like All submenus primarily were rendered in the same line. Only by adding the MenuSeparator I was able to divide them.
I'm lost I've found the example in the Internet, that shows exactly what I need (including the right-hand arrow for submenus) Example . I've used exactly the same algorithm to create menu. But I cannot get the same result.
Please, help.
I've noted that the image is not accessible.
In pure text it looks like:
Final 1
Final 2
Final 3
DropDown 1
DropDown 2
Indent depends on the submenu width.
Think, now I know what happened (don't know though, how to work around it).
The problem is the widget rendering.
The final menu option (leaf) is rendered as table row (tr and td tags).
The PopupMenuItem is rendered as div between rows.
Once more, I have no clue, how to avoid it.
Here is the code. A couple of notes:
1.The rows is the two dimensional array
2.The rows with ParentID=0 are the MenuBarItems
3.pM is the MenuBar widget
createMenu: function (rows, pM) {
var me = this; // for references from the event handlers, where 'this' means event origin (instead of lang.hitch)
// First define the indexes of the DB fields
var xMenu_Id;
var xMenu_Title;
var xParent;
var xURL;
var xUser_Roles;
var i;
for (i = 0; i < rows[0].length; i++) {
switch (rows[0][i]) {
case 'Menu_Id':
xMenu_Id = i;
break;
case 'Menu_Title':
xMenu_Title = i;
break;
case 'Parent':
xParent = i;
break;
case 'URL':
xURL = i;
break;
case 'User_Roles':
xUser_Roles = i;
break;
}
}
// Define the function to filter the menu rows
// Parameters: r - two-dimentional rows array
// p - criterion (the parent menu ID)
// idx - index of needed field
// f - returned filtered array (no need to use in calling statement)
var filterArray = function (r, p, idx, f) {
f = dojo.filter(r, function (item) {
return item[idx] == p;
});
return f;
}
// Define the recurcive function to create the sub menu tree for Menu bar item
// Parameters: parentMenu - the menu to add childs
// parentID - the ID of parent menu to select direct children
// role - current user role
var subMenuFactory = function (parentMenu, parentID, role) {
var i;
var fa = filterArray(rows, parentID, xParent);
var sub;
for (i = 0; i < fa.length; i++) {
if (fa[i][xUser_Roles].indexOf(role) >= 0 || fa[i][xUser_Roles] == 'all') {
if (fa[i][xURL] != '0') { // leaf
url = fa[i][xURL];
parentMenu.addChild(new MenuItem({
dir: 'ltr',
label: fa[i][xMenu_Title],
action: fa[i][xURL],
onClick: function () { me.menuAction(this.action); }
}));
}
else { // DropDown Node
sub = new DropDownMenu({ dir: 'ltr' });
subMenuFactory(sub, fa[i][xMenu_Id], role);
parentMenu.addChild(new MenuSeparator({}));
parentMenu.addChild(new PopupMenuBarItem({
dir: 'ltr',
label: fa[i][xMenu_Title],
popup: sub
}));
}
}
}
}
// Get array of Menu bar items
var filtered = filterArray(rows, 0, xParent);
var pSub;
var user_Role = this.user.Role;
for (i = 0; i < filtered.length; i++) {
if (filtered[i][xUser_Roles].indexOf(user_Role) >= 0 || filtered[i][xUser_Roles]=='all') {
if (filtered[i][xURL] != '0') // leaf
{
pM.addChild(new MenuBarItem({
dir: 'ltr',
label: filtered[i][xMenu_Title],
action: filtered[i][xURL],
onClick: function () { me.menuAction(this.action); }
}));
}
else { // DropDown Node
pSub = new DropDownMenu({ dir: 'ltr' });
subMenuFactory(pSub, filtered[i][xMenu_Id],user_Role);
pM.addChild(new PopupMenuBarItem({
dir: 'ltr',
label: filtered[i][xMenu_Title],
popup: pSub
}));
}
}
}
},
I've found what's the problem. In the required array of define I erroneously import PopupMenubarItem instead of PopupMenuItem. In the function the parameter is named right - PopupMenuItem, but evidently it couldn't help a lot...
Thanks to everyone who tried to help me.

Not sure why facebook refered me here but anyhow, let me ask the question. I have a group on facebook with over 4000 members. I want to delete old members that are not active on the group anymore. Is there a way to select multiple users for deletion?
How to get a list of ID's of your facebook group to avoid removal of active users, it's used to reduce as well a group from 10.000 to 5000 members as well as removal of not active members or old members "You will risk removing some few viewers of the group" "remember to open all comments while you browse down the page":
You will need to have Notepad++ for this process:
After you save the HTML. Remove all information before of document:
"div id=contentArea" to
"div id=bottomContent"
to avoid using messenger ID's,
somehow script will run problems if you have ID's by blocked users.
As well as a different example of how to parse as well as text and code out of HTML. And a range of numbers if they are with 2 digits up to 30.
You can try this to purge the list of member_id= and with them along with numbers from 2 to up to 30 digits long. Making sure only numbers and whole "member_id=12456" or "member_id=12" is written to file. Later you can replace out the member_id= with blanking it out. Then copy the whole list to a duplicate scanner or remove duplicates. And have all unique ID's. And then use it in the Java code below.
"This is used to purge all Facebook user ID's by a group out of a single HTML file after you saved it scrolling down the group"
Find: (member_id=\d{2,30})|.
Replace: $1
You should use the "Regular Expression" and ". matches newline" on above code.
Second use the Extended Mode on this mode:
Find: member_id=
Replace: \n
That will make new lines and with an easy way to remove all Fx0 in all lines to manually remove all the extra characters that come in buggy Notepad++
Then you can easily as well then remove all duplicates. Connect all lines into one single space between. The option was to use this tool which aligns the whole text with one space between each ID: https://www.tracemyip.org/tools/remove-duplicate-words-in-text/
As well then again "use Normal option in Notepad++":
Find: "ONE SPACE"
Replace ','
Remember to add ' to beginning and end
Then you can copy the whole line into your java edit and then remove all members who are not active. If you though use a whole scrolled down HTML of a page. ['21','234','124234'] <-- remember right characters from beginning. Extra secure would be to add your ID's to the beginning.
You put your code into this line:
var excludedFbIds = ['1234','11223344']; // make sure each id is a string!
The facebook group removal java code is on the user that as well posted to this solution.
var deleteAllGroupMembers = (function () {
var deleteAllGroupMembers = {};
// the facebook ids of the users that will not be removed.
// IMPORTANT: bobby.leopold.5,LukeBryannNuttTx!

I am trying to retrieve the line number in dojo data grid. rowIndex function would not help me much because I need the 'line number' and NOT 'row number' when sorted.
The scenario:
I would like to set the focus on one specific row and this focus should remain even after sorting. But if I use the code below, it does not select the correct row.
For example, the index 1 is on the 5th line after sorting. However, the e.item.id still remains as 1, expected is 5.
calendar.on("itemClick", function (e)
{
MyGrid.doclick({ rowIndex: e.item.id });
MyGrid.scrollToRow(e.item.id);
});
Additionally, I also tried...
calendar.on("itemClick", function (e)
{
var identity = MyGrid._by_idx[e.item.id].idty;
var gridItem = MyGrid.getItem(identity);
var gridItemIndex = MyGrid.getItemIndex(gridItem);
MyGrid.doclick({ rowIndex: gridItemIndex });
MyGrid.scrollToRow(e.item.id);
});
Could you please let me know how to get the correct row after fitering? I thank you for your time.
Wishes,
Santosh
Okay, I figured out the answer.
GetGridItemIndexByGridItem = function (gridItem) {
var indexLength = MyGrid._by_idx.length;
var element = null;
var gridItemIndex = -1;
for (var i = 0; i < indexLength; i++) {
element = MyGrid._by_idx[i];
if (element.item.Guid == gridItem.Guid) {
gridItemIndex = i;
}
}
return gridItemIndex;
}
Best Wishes
