ColVis - DataTable HTML sourced - javascript

I have a problem with my DataTable. I want to use ColVis plug-in.
My Table is initialised by HTML table - DOM Object.
var colvis = new $.fn.dataTable.ColVis( oTable );
$( colvis.button() ).insertAfter('div.info');
This is how I creating the button, but the button isn't visible. I downloaded full js file (not minimalized) and have following error:
"Uncaught TypeError: Cannot read property 'length' of undefined"
in this function:
"_fnAddButtons": function ()
{
var
nButton,
columns = this.s.dt.aoColumns;
if ( $.inArray( 'all', this.s.aiExclude ) === -1 ) {
for ( var i=0, iLen=columns.length ; i<iLen ; i++ )
{
if ( $.inArray( i, this.s.aiExclude ) === -1 )
{
nButton = this._fnDomColumnButton( i );
nButton.__columnIdx = i;
this.dom.buttons.push( nButton );
}
}
}
if ( this.s.order === 'alpha' ) {
this.dom.buttons.sort( function ( a, b ) {
var titleA = columns[ a.__columnIdx ].sTitle;
var titleB = columns[ b.__columnIdx ].sTitle;
return titleA === titleB ?
0 :
titleA < titleB ?
-1 :
1;
} );
}
if ( this.s.restore )
{
nButton = this._fnDomRestoreButton();
nButton.className += " ColVis_Restore";
this.dom.buttons.push( nButton );
}
if ( this.s.showAll )
{
nButton = this._fnDomShowAllButton();
nButton.className += " ColVis_ShowAll";
this.dom.buttons.push( nButton );
}
$(this.dom.collection).append( this.dom.buttons );
},
he tells that the
columns = this.s.dt.aoColumns;
is undefined.
Can someone help me?

Javascript Push is overwriting the previous elements

I am trying render the plotly.js graph,
For some reason though, the traces.push(this.getTrace(val, calAdjustData)) part seems to be overwriting previous data in the traces array, For every iteration it is returns single value, but finally last value is overwriting all previous values.
destArray.forEach(val=> {
traces.push(this.getTrace(val, calAdjustData));
});
getTrace() function is
getTrace(trace:any, data:any) {
let appConfig: any = [];
appConfig['TABLES'] = {

Please suggest any solution for this issue, already few similar questions here, but nothing worked for me.

Need to fix broken icons in crypto chart based on vue js

I'm using a Vue Js cryptocurrency chart which displays the latest prices of a list of cryptocurrencies, the problem is that there are a lot of icons links that are broken, but it's not like I can fix them individually, they're all retrieved from a github iconbase. Is there any way I can fix that or at least set a default "No image" icon to show up where there's no icon?
Part responsible for retrieving the icons:
// vue instance
new Vue({
// mount point
el: '#app',
// app data
data: {
endpoint : 'wss://stream.binance.com:9443/ws/!ticker#arr',
iconbase : 'https://raw.githubusercontent.com/rainner/binance-watch/master/public/images/icons/',
cache : {}, // coins data cache
coins : [], // live coin list from api
asset : 'USDT', // filter by base asset pair
search : '', // filter by search string
sort : 'assetVolume', // sort by param
order : 'desc', // sort order ( asc, desc )
limit : 50, // limit list
status : 0, // socket status ( 0: closed, 1: open, 2: active, -1: error )
sock : null, // socket inst
cx : 0,
cy : 0,
},
My full Js:
// common number filters
Vue.filter( 'toFixed', ( num, asset ) => {
if ( typeof asset === 'number' ) return Number( num ).toFixed( asset );
return Number( num ).toFixed( ( asset === 'USDT' ) ? 3 : 8 );
});
Vue.filter( 'toMoney', num => {
return Number( num ).toFixed( 0 ).replace( /./g, ( c, i, a ) => {
return i && c !== "." && ( ( a.length - i ) % 3 === 0 ) ? ',' + c : c;
});
});

I know 2 tricks for broken link images:
The first is to hide the images with broken link:
<img :src="c.icon" :alt="c.pair" onerror="this.style.display='none'"/>
The second is to use a default image from your choice and display it in case the image link is broken. Like the following where I took one of your images as a default image
<img :src="c.icon" :alt="c.pair" onerror="this.src='https://raw.githubusercontent.com/rainner/binance-watch/master/public/images/icons/xtz_.png'" />
Here is a Demo

jQuery html property...?

Alright... My HTML looks like this:
<div id="_content"></div>
And then, there is a method like this:
Main.LoadContent(source, target)
{
var reader = new FileReader();
var s = '';
reader.onload = function()
{
s = reader.result;
var t = $(target).html;
alert(t);
t.html = s;
}
var f = new File([""], source);
reader.readAsText(f);
}
Mind the 'alert(t)' line, it returns:
function ( value ) {
return access( this, function( value ) {
var elem = this[ 0 ] || {},
i = 0,
l = this.length;
if ( value === undefined ) {
return elem.nodeType === 1 ?
elem.innerHTML.replace( rinlinejQuery, "" ) :
undefined;
}
// See if we can take a shortcut and just use innerHTML
if ( typeof value === "string" && !rnoInnerhtml.test( value ) &&
( support.htmlSerialize || !rnoshimcache.test( value ) ) &&
( support.leadingWhitespace || !rleadingWhitespace.test( value ) ) &&
!wrapMap[ (rtagName.exec( value ) || [ "", "" ])[ 1 ].toLowerCase() ] ) {
value = value.replace( rxhtmlTag, "<$1></$2>" );
try {
for (; i < l; i++ ) {
// Remove element nodes and prevent memory leaks
elem = this[i] || {};
if ( elem.nodeType === 1 ) {
jQuery.cleanData( getAll( elem, false ) );
elem.innerHTML = value;
}
}
elem = 0;
// If using innerHTML throws an exception, use the fallback method
} catch(e) {}
}
if ( elem ) {
this.empty().append( value );
}
}, null, value, arguments.length );
}
The call to Main.LoadContent looks like this:
Main.LoadContent('start.htf', '#_content');
What's my sublime stupidity come to here...???
HTML is a function... put the s variable inside of the function to set the HTML... see what that gets you. Example:
Main.LoadContent(source, target)
{
var reader = new FileReader();
var s = '';
reader.onload = function()
{
s = reader.result;
var t = $(target).html();
alert(t);
//t.html(s);
$(target).html(s);
}
var f = new File([""], source);
reader.readAsText(f);
}

R datatable rowCallback with DT

I am trying to perform two distinct formatting operations on a datatable object using the DT and magrittr packages. One uses the helper function formatRound() and the other is passed in as JavaScript to a rowCallback option in the datatable function.
When I run either of the formatting operations individually the datatable renders with the expected formatting. However, when I run both together the datatable renders blank but I do not get an error.
This code shows the behavior I am describing.
library(magrittr)
library(DT)
df = data.frame(matrix(rnorm(20), nrow=10))
datatable(
data = df
) %>%
formatRound(c("X1", "X2"), 1)
#table renders as expected
datatable(
data = df,
options = list(
rowCallback = JS("
function( row, data, index ) {
if ( index > 2 ) {
$(row).css('background-color', '#EDEDED');
}
else if ( index > 0 ) {
$(row).css('background-color', '#DEDEDE');
}
else {
$(row).css('background-color', '#D3D3D3');
}
}"
)
)
)
#table renders as expected
datatable(
data = df,
options = list(
rowCallback = JS("
function( row, data, index ) {
if ( index > 2 ) {
$(row).css('background-color', '#EDEDED');
}
else if ( index > 0 ) {
$(row).css('background-color', '#DEDEDE');
}
else {
$(row).css('background-color', '#D3D3D3');
}
}"
)
)
) %>%
formatRound(c("X1", "X2"), 1)
#table renders as blank but with no error returned
If you have a look at the JS function of your third attempt in the browser's JS console(click on "Inspect Element option in browser"), it shows up an error saying that 'var' is unidentified because it is outside the scope of the JS function:
(
var d = parseFloat(data[1]); $(this.api().cell(row, 1).node()).html(isNaN(d) ? '' : d.toFixed(1));
var d = parseFloat(data[2]); $(this.api().cell(row, 2).node()).html(isNaN(d) ? '' : d.toFixed(1));
function( row, data, index ) {
if ( index > 2 ) {
$(row).css('background-color', '#EDEDED');
}
else if ( index > 0 ) {
$(row).css('background-color', '#DEDEDE');
}
else {
$(row).css('background-color', '#D3D3D3');
}
})
If you put those two lines inside the JS function, it works perfectly.
You can find the updated code below.
datatable(
data = df,
options = list(
rowCallback = JS("
function( row, data, index ) {
var d = parseFloat(data[1]);
$(this.api().cell(row, 1).node()).html(isNaN(d) ? '' : d.toFixed(1));
var d = parseFloat(data[2]);
$(this.api().cell(row, 2).node()).html(isNaN(d) ? '' : d.toFixed(1));
if ( index > 2 ) {
$(row).css('background-color', '#EDEDED');
}
else if ( index > 0 ) {
$(row).css('background-color', '#DEDEDE');
}
else {
$(row).css('background-color', '#D3D3D3');
}
}"
)
)
)

jQuery Datatables and ColumnFilterWidget integration issue

I am trying to Place the ColumnFilterWidget plugin in the Header of the Datatables Table.
Here are the changes i made in it :
/**
* Menu-based filter widgets based on distinct column values for a table.
*
* #class ColumnFilterWidgets
* #constructor
* #param {object} oDataTableSettings Settings for the target table.
*/
var ColumnFilterWidgets = function( oDataTableSettings ) {
var me = this;
var sExcludeList = '';
// me.$WidgetContainer = $( '<div class="column-filter-widgets"></div>' );
me.$WidgetContainer = $( '<tr class="head"></tr>' );
me.$MenuContainer = me.$WidgetContainer;
me.$TermContainer = null;
me.aoWidgets = [];
me.sSeparator = '';
if ( 'oColumnFilterWidgets' in oDataTableSettings.oInit ) {
if ( 'aiExclude' in oDataTableSettings.oInit.oColumnFilterWidgets ) {
sExcludeList = '|' + oDataTableSettings.oInit.oColumnFilterWidgets.aiExclude.join( '|' ) + '|';
}
if ( 'bGroupTerms' in oDataTableSettings.oInit.oColumnFilterWidgets && oDataTableSettings.oInit.oColumnFilterWidgets.bGroupTerms ) {
me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
me.$TermContainer = $( '<div class="column-filter-widget-selected-terms"></div>' ).hide();
}
}
// Add a widget for each visible and filtered column
$.each( oDataTableSettings.aoColumns, function ( i, oColumn ) {
var $columnTh = $( oColumn.nTh );
var $WidgetElem = $( '<th><div class="column-filter-widget"></div></th>' );
if ( oColumn.bVisible && sExcludeList.indexOf( '|' + i + '|' ) < 0 ) {
me.aoWidgets.push( new ColumnFilterWidget( $WidgetElem, oDataTableSettings, i, me ) );
}
me.$MenuContainer.append( $WidgetElem );
} );
if ( me.$TermContainer ) {
me.$WidgetContainer.append( me.$MenuContainer );
me.$WidgetContainer.append( me.$TermContainer );
}
oDataTableSettings.aoDrawCallback.push( {
name: 'ColumnFilterWidgets',
fn: function() {
$.each( me.aoWidgets, function( i, oWidget ) {
oWidget.fnDraw();
} );
}
} );
return me;
};
I added a extra <tr class='head'> inside the Datatable, and later on i am trying to append the Filters to that with attached to them,But instead of that it is creating new TR tag and then appending the filters in it.
I even changed my dom of data tables to : dom: '<"clear">Cf<"clear">ltWrip',
So the table elements should be there so that it can insert filters inside the head.

Here is it if anyone else needs it .
Add a <TR id='Filter.$i'> element in the html
Use a for loop and append the counter value to the ID.
then modified the column.filterwidget plugn js
var ColumnFilterWidgets = function( oDataTableSettings ) {
var me = this;
var sExcludeList = '';
me.$WidgetContainer = $( '<div class="column-filter-widgets"></div>' );
me.$MenuContainer = me.$WidgetContainer;
me.$TermContainer = null;
me.aoWidgets = [];
me.sSeparator = '';
if ( 'oColumnFilterWidgets' in oDataTableSettings.oInit ) {
if ( 'aiExclude' in oDataTableSettings.oInit.oColumnFilterWidgets ) {
sExcludeList = '|' + oDataTableSettings.oInit.oColumnFilterWidgets.aiExclude.join( '|' ) + '|';
}
if ( 'bGroupTerms' in oDataTableSettings.oInit.oColumnFilterWidgets && oDataTableSettings.oInit.oColumnFilterWidgets.bGroupTerms ) {
me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
me.$MenuContainer = $( '<div class="column-filter-widget-menus"></div>' );
me.$TermContainer = $( '<div class="column-filter-widget-selected-terms"></div>' ).hide();
}
}
var cnt= 0;
// Add a widget for each visible and filtered column
$.each( oDataTableSettings.aoColumns, function ( i, oColumn ) {
var $columnTh = $( oColumn.nTh );
cnt ++;
var $WidgetElem = $( '<div class="column-filter-widget" id=col'+cnt+'></div>' );
if ( oColumn.bVisible && sExcludeList.indexOf( '|' + i + '|' ) < 0 ) {
me.aoWidgets.push( new ColumnFilterWidget( $WidgetElem, oDataTableSettings, i, me ) );
}
var Tcol = document.getElementById('A');
console.log('---------'+i);
//me.$MenuContainer.append( $WidgetElem );
$('#Filter'+i).append( $WidgetElem );
} );
if ( me.$TermContainer ) {
me.$WidgetContainer.append( me.$MenuContainer );
me.$WidgetContainer.append( me.$TermContainer );
}
oDataTableSettings.aoDrawCallback.push( {
name: 'ColumnFilterWidgets',
fn: function() {
$.each( me.aoWidgets, function( i, oWidget ) {
oWidget.fnDraw();
} );
}
} );
return me;
};
Hope this helps.
