Kendo Grid enter key press event handling - kendo-ui

In a Kendo-grid I have to Manage enter key event.If a user press Enter Key inside a cell ,The cell focus must be move to a given cell index and put it to editabale mode.For textbox i Have done that part but for Kendo Dropdown it only focus but not change to edit mode.
My code is
edit: function (e) {
var sender = e.sender;
var cellToEdit = sender.content.find("td:eq(0)");
var input = e.container.find(".k-input");
var td = input.closest("td");
var rowIndex = td.parent().index();
var cellIndex = td.index();
input.on("keydown", function (event) {
if (event.keyCode == 13) {
debugger;//Check the current cell index
if (cellIndex == 2) {
debugger;
cellIndex = 3;//wanted to focus cell index next
var cellCloseT = $('#grid').data("kendoGrid").closeCell($(".k-grid-content").find("table").find("tbody").find("tr:eq(" + rowIndex + ")").find("td:eq(" + cellIndex + ")").parent());
$('#grid').data("kendoGrid").editCell($(".k-grid-content").find("table").find("tbody").find("tr:eq(" + rowIndex + ")").find("td:eq(" + cellIndex + ")").next().focusin(cellCloseT));
return false;
}
else if (cellIndex == 4) {
debugger;
cellIndex = 5;
var cellCloseT = $('#grid').data("kendoGrid").closeCell($(".k-grid-content").find("table").find("tbody").find("tr:eq(" + rowIndex + ")").find("td:eq(" + cellIndex + ")").parent());

sender.editCell(cellToEdit);
return false;
}
else if (cellIndex == 6) {
debugger;
cellIndex = 7;
var cellCloseT = $('#grid').data("kendoGrid").closeCell($(".k-grid-content").find("table").find("tbody").find("tr:eq(" + rowIndex + ")").find("td:eq(" + cellIndex + ")").parent());

jQuery Bezier.js Plugin not redrawing on window resize

Working with this plugin. Demo here https://www.jqueryscript.net/demo/animated-lines-elements-bezier/
On this demo when you resize the page it redraws. When I use this locally it doesn't redraw and the reason seems to be the this.selector is undefined when I run locally so after it clears the svg's it can't recreate them. Anyone have any idea why this might be?
See // Bug: comment below. Is this.selector a special variable for jquery plugins because I don't see it defined anywhere here, but the demo works so not sure how.

Getting a 500 Internal Server Error Jquery

While everything is running in the software, I get this error when I make a selection from the dropdown list in only one part. Where am I making a mistake? or is it a server error?
I have not received this error in any Laravel before. When trying to get something from a dropdown list, this error comes to the console and there is no reaction on the site.

NVD3: Add the 'total' value to stackedAreaChart's interactiveGuideline

Is there a simple way to include the TOTAL value in the stackedAreaChart's interactiveGuideline tooltip? It'd be great if I could display total users using this awesome tooltip as well.
If not, what's the cleanest alternative?
You can use interactiveGuideline.tooltip.contentGenerator
https://github.com/novus/nvd3/blob/master/src/tooltip.js#L316
e.g.
chart.multiChart.interactiveLayer.tooltip.contentGenerator(function(d) {
var header = d.value;
var headerhtml =
"<thead><tr><td colspan='3'><strong class='x-value'>" +
header +
"</strong></td></tr></thead>";
var bodyhtml = "<tbody>";
var series = d.series;
series.forEach(function(c) {
var value = (c.value || 0).toFixed(2);
if (
c.key === keyForActualGreaterThanPredicted ||
c.key === keyForActualLessThanPredicted
) {
var diff = Math.abs(c.data.y0 - c.data.y1);
if (diff === 0) {
value = "-";
} else {
value = diff.toFixed(2);
}
}
bodyhtml =
bodyhtml +
"<tr><td class='legend-color-guide'><div style='background-color: " +
c.color +
";'></div></td><td class='key'>" +
c.key +
"</td><td class='value'>" +
value +
"</td></tr>";
});
bodyhtml = bodyhtml + "</tbody>";
return "<table>" + headerhtml + "" + bodyhtml + "</table>";

Scroll Events in TouchGridPanel

I am building a mobile application using Sencha Touch 1.0. I need to display report, for that am using grid given by Ext.ux.TouchGridPanel.
It is working fine.
Where as I need to capture Scroll event in Ext.ux.TouchGridPanel.
I have added 'scroll' in bubble event of Dataview.
I am also trying to capture the event after the Dataview created.
But nothing seems to be working. Below is the code which I have changed.
Does anybody has any idea how to capture the start of scroll event?
Thanks in advance.
Ext.ux.TouchGridPanel = Ext.extend(Ext.Panel, {
layout: "fit",
multiSelect: false,
initComponent: function () {
var me = this;
me.items = me.dataview = me.buildDataView();
Ext.ux.TouchGridPanel.superclass.initComponent.call(me);
var store = me.store;
store.on("update", me.dispatchDataChanged, me);
var dataview = me.dataview;
dataview.on('scroll', me.startScroll);
},
dispatchDataChanged: function (store, rec, operation) {
var me = this;
me.fireEvent("storeupdate", store, rec, operation);
},
startScroll: function (scroller, offset) {
console.log('is this event captured???')
var me = this;
me.fireEvent("scroll", this.scroller, offset);
},
buildDataView: function () {
var me = this, colModel = me.colModel, colNum = me.getColNum(false), cellWidth = 100 / colNum,
colTpl = '<div class="x-grid-head">';
colTpl += '<thead><tr class="x-grid-header">';
for (var i = 0; i < colModel.length; i++) {
var col = colModel[i];
var width = (Ext.isDefined(col.width)) ? ("width =" + (col.width - 4) + "%") : '';
colTpl += '<th class="x-grid-cell" ' + width + ' style="' + col.style + '" >' + col.header + '</th>';
}
colTpl += '</tr></thead>';
colTpl += '<tbody ><tpl for="."><tr class="x-grid-row">';
for (var i = 0; i < colModel.length; i++) {
var col = colModel[i];
var width = (Ext.isDefined(col.width)) ? ("width =" + col.width + "%") : '';
colTpl += '<td class="x-grid-cell" style="' + col.style + '" >{' + col.mapping + '}</td>';
}
colTpl += '</tr></tpl></tbody>';
colTpl += '</table></div>'
return new Ext.DataView({
store: me.store,
itemSelector: "tr.x-grid-row",
simpleSelect: me.multiSelect,
scroll: me.scroll,
tpl: new Ext.XTemplate(colTpl,
{
isRowDirty: function (dirty, data) {
return dirty ? "x-grid-row-dirty" : "";
}
}
),
prepareData: function (data, index, record) {
var column,
i = 0,
ln = colModel.length;
var prepare_data = {};
prepare_data.dirtyFields = {};
for (; i < ln; i++) {
column = colModel[i];
if (typeof column.renderer === "function") {
prepare_data[column.mapping] = column.renderer.apply(me, [data[column.mapping], column, record, index]);
} else {
prepare_data[column.mapping] = data[column.mapping];
}
}
prepare_data.isDirty = record.dirty;
prepare_data.rowIndex = index;
return prepare_data;
},
bubbleEvents: [
"beforeselect",
"containertap",
"itemdoubletap",
"itemswipe",
"itemtap",
"selectionchange",
"scroll"
]
});
},
// #private
onScrollStart: function () {
console.log("Are you coming here");
var offset = this.scroller.getOffset();
this.closest = this.getClosestGroups(offset);
this.setActiveGroup(this.closest.current);
},
// #private
onScroll: function (scroller, pos, options) {
}
});
Ext.reg("touchgridpanel", Ext.ux.TouchGridPanel);
We can directly access dataview scroller and check event of the same.
For eg.
newGrid = new Ext.ux.TouchGridPanel({....
after creation of the Panel just access its dataview scroller
newGrid.dataview.scroller.on('scroll', scrollGrid1);
var scrollGrid1 = function(scroller, offsets){
console.log(' Grid scrolling with offset ' + offsets.x + ' & ' + offsets.y);
}

Twitter and jQuery , render tweeted links

I am using jquery ajax to pull from the twitter api, i'm sure there's a easy way, but I can't find it on how to get the "tweet" to render any links that were tweeted to appear as a link. Right now it's only text.
$.ajax({
type : 'GET',
dataType : 'jsonp',
url : 'http://search.twitter.com/search.json?q=nettuts&rpp=2',
success : function(tweets) {
var twitter = $.map(tweets.results, function(obj, index) {
return {
username : obj.from_user,
tweet : obj.text,
imgSource : obj.profile_image_url,
geo : obj.geo
};
});

The following function (plugin) works perfectly.
(function($) {
$.socialFader = function(options) {
var settings = {

$.extend(settings, options);

var relative_to = (arguments.length > 1) ? arguments[1] : new Date();
var delta = parseInt((relative_to.getTime() - parsed_date) / 1000);
delta = delta + (relative_to.getTimezoneOffset() * 60);
var r = '';
if (delta < 60) {

You need to parse the tweet content, find the urls and then put them in between yourself.
Unfortunately, at the moment, the search API doesn't have the facility to break out tweet entities (i.e., links, mentions, hashtags) like some of the REST API methods. So, you could either parse out the entities yourself (I use regular expressions) or call back into the rest API to get the entities.
If you decide to call back into the REST API, and once you have extracted the status ID from the search API results, you would make a call to statuses/show like the following:
http://api.twitter.com/1/statuses/show/60183527282577408.json?include_entities=true
In the resultant JSON, notice the entities object.
"entities":{"urls":[{"expanded_url":null,"indices":[68,88],"url":"http:\/\/bit.ly\/gWZmaJ"}],"user_mentions":[],"hashtags":[{"text":"wordpress","indices":[89,99]}]}
You can use the above to locate the specific entities in the tweet (which occur between the string positions denoted by the indices property) and transform them appropriately.
If you prefer to parse the entities yourself, here are the (.NET Framework) regular expressions I use:
Link Match Pattern
(?:<\w+.*?>|[^=!:'"/]|^)((?:https?://|www\.)[-\w]+(?:\.[-\w]+)*(?::\d+)?(?:/(?:(?:[~\w\+%-]|(?:[,.;#:][^\s$]))+)?)*(?:\?[\w\+%&=.;:-]+)?(?:\#[\w\-\.]*)?)(?:\p{P}|\s|<|$)
Mention Match Pattern
\B#([\w\d_]+)
Hashtag Match Pattern
(?:(?:^#|[\s\(\[]#(?!\d\s))(\w+(?:[_\-\.\+\/]\w+)*)+)
Twitter also provides an open source library that helps capture Twitter-specific entities like links, mentions and hashtags. This java file contains the code defining the regular expressions that Twitter uses, and this yml file contains test strings and expected outcomes of many unit tests that exercise the regular expressions in the Twitter library.
How you process the tweet is up to you, however I process a copy of the original tweet, and pull all the links first, replacing them in the copy with spaces (so as not to modify the string length.) I capture the start and end locations of the match in the string, along with the matched content. I then pull mentions, then hashtags -- again replacing them in the tweet copy with spaces.
This approach ensures that I don't find false positives for mentions and hashtags in any links in the tweet.
I slightly modified previous one. Nothing lefts after all tweets disappears one by one.
Now it checks if there is any visible tweets and then refreshes tweets.
