Chartist.js - Pass Label Value into Bar Click - javascript

I am using the Chartist.js graph api to create a graph and I need each bar to click to a location. This is easy enough, but I also need to pass the corresponding label value if possible.
var graph = new Chartist.Bar('.ct-chart', {
labels : ['L1','L2','L3'],
series : [1,2,3]
});
So, I have added an onclick method to each bar, but need it to get the corresponding label value to pass to the location page. Example:
graph.on('created', function() {
$('.ct-bar').click(function () {
var val = $(this).attr('ct:value');
if (val > 0) {
window.location = 'location/?label=BAR LABEL HERE (eg: L1)';
}
});
});
Would anyone know if this is possible?
Many thanks.

Detect onHover being complete on a Chart.js doughnut chart

I have a Chart.js doughnut chart (v2.7.1) and I am looking to set the class of an external element when the user hovers over the relevant chart element
I can use the onHover event within the options.hover of the chart
hover: {
onHover: function (evt, item) {
if (item.length) {
var index = item[0]._index;
var legendElement = $(#get element based on index#);
legendElement.addClass('active');
}
}
}
and this sets the class on the element (legendElement) perfectly but I need to be able to remove the class I set from the element when the user is no longer hovering over the element
Am I using the correct approach? Is there a way to detect that the onHover is complete or that the segment is no longer in focus?
Are you defining an "events" property apart from the "onHover" property? If you add "mouseout" to the list, the "onHover" function will be called in both cases. Check out the documentation for this https://www.chartjs.org/docs/latest/general/interactions/events.html
An example code that might work:
options: {
events: ["mousemove", "mouseout"],
onHover: function (evt, item) {
if (item.length) {
var index = item[0]._index;
var legendElement = $(#get element based on index#);
if(evt.type == "mousemove"){
legendElement.addClass('active');
}else{
legendElement.removeClass('active');
}
}
}
}

Store click value to use later on

Basically, I have an appointment form which is broken down into panels.
Step 1 - if a user clicks london (#Store1) then hide Sunday and Monday from the calendar in panel 5.
Basically, I want to store this click so that when the user gets to the calendar panel, it will know not to show Sunday and Monday
$('#store1').click(function () {
var $store1 = $(this).data('clicked', true);
console.log("store 1 clicked");
$('.Sunday').hide();
$('.Monday').hide();
});
after I have captured this in a var I then want to run it when the calendar displays.
function ReloadPanel(panel) {
return new Promise(function (resolve, reject, Store1) {
console.log(panel);
console.log("finalpanel");
panel.nextAll('.panel').find('.panel-updater').empty();
panel.nextAll('.panel').find('.panel-title').addClass('collapsed');
panel.nextAll('.panel').find('.panel-collapse').removeClass('in');
var panelUpdater = $('.panel-updater:eq(0)', panel),
panelUrl = panelUpdater.data('url');
if (panelUpdater.length) {
var formData = panelUpdater.parents("form").serializeObject();
panelUpdater.addClass('panel-updater--loading');
panelUpdater.load(panelUrl, formData, function (response, status) {
panelUpdater.removeClass('panel-updater--loading');
if (status == "error") {
reject("Panel reload failed");
} else {
resolve("Panel reloaded");
}
});
} else {
resolve("no reloader");
}
});
}
I'm not sure if this is even written right, so any help or suggestions would be great
Thanks in advance
Don't think of it as "storing a click". Instead, consider your clickable elements as having some sort of data values and you store the selected value. From this value you can derive changes to the UI.
For example, consider some clickable elements with values:
<button type="button" class="store-button" data-store-id="1">London</button>
<button type="button" class="store-button" data-store-id="2">Paris</button>
<button type="button" class="store-button" data-store-id="3">Madrid</button>
You have multiple "store" buttons. Rather than bind a click event to each individually and customize the UI for each click event, create a single generic one which captures the clicked value. Something like:
let selectedStore = -1;
$('.store-button').on('click', function () {
selectedStore = $(this).data('store-id');
});
Now anywhere that you can access the selectedStore variable can know the currently selected store. Presumably you have some data structure which can then be used to determine what "days" to show/hide? For example, suppose you have a list of "stores" each with valid "days":
let stores = [
{ id: 1, name: 'London', days: [2,3,4,5,6] },
// etc.
];
And your "days" buttons have their corresponding day ID values:
<button type="button" class="day-button" data-day-id="1">Sunday</button>
<button type="button" class="day-button" data-day-id="2">Monday</button>
<!--- etc. --->
You can now use the data you have to derive which buttons to show/hide. Perhaps something like this:
$('.day-button').hide();
for (let i in stores) {
if (stores[i].id === selectedStore) {
for (let j in stores[i].days) {
$('.day-button[data-day-id="' + stores[i].days[j] + '"]').show();
}
break;
}
}
There are a variety of ways to do it, much of which may depend on the overall structure and flow of your UX. If you need to persist the data across multiple pages (your use of the word "panels" implies more of a single-page setup, but that may not necessarily be the case) then you can also use local storage to persist things like selectedStore between page contexts.
But ultimately it just comes down to structuring your data, associating your UI elements with that data, and performing logic based on that data to manipulate those UI elements. Basically, instead of manipulating UI elements based only on UI interactions, you should update your data (even if it's just in-memory variables) based on UI interactions and then update your UI based on your data.
you can use the local storage for that and then you can get your value from anywhere.
Set your value
localStorage.setItem("store1", JSON.stringify(true))
Get you value then you can use it anywhere:
JSON.parse(localStorage.getItem("store1"))
Example:
$('#store1').click(function() {
var $store1 = $(this).data('clicked', true);
localStorage.setItem("store1", JSON.stringify(true))
console.log("store 1 clicked");
$('.Sunday').hide();
$('.Monday').hide();
});

SAPUI5 TreeTable's getRows method returns empty array on the first call

I am trying to build an SAPUI5 application using TreeTable and I'm facing some problems to use its methods.
In my app, I have a button which triggers this method.
onChangeViewContext: function(oEvent) {
.........
.........
var aViewContext = oContext.oModel.getProperty(sPath + "/ViewContext");
var aDataModel = oContext.oModel.getProperty("/ApplicationCollection/" + sAppId + "/DataModel");
var oStructure = this._createParentChildStructure(aDataModel);
var oTreeModel = this.getView().getModel("treeModel");
oTreeModel.setData(oStructure);
this._oViewDetailLine = oSource.getParent().getParent().getParent();
this._oViewDetailLine.setVisible(false);
this.byId("idSelectElementsPanel").setVisible(true);
this._setSelectedItems(aViewContext, oTree);
}
What I'm trying to do here is only bind the rows with my treeModel, get tree table object and send it to my _setSelectedItems method which below.
_setSelectedItems: function(aViewContext, oTree) {
oTree.clearSelection();
var sElementName;
var aSelectedIndices = [];
var aElements = [];
var aRows = oTree.getRows();
aRows.forEach(function(row) {
if (row._oNodeState !== undefined) {
aElements.push(row.getCells()[0].getText());
}
});
I need to get rows array here because I will use it for setting selected items of tree table. The problem is when "onChangeViewContext" triggered, oTable.getRows() returns an empty array. But when I click cancel button (which just hides my tree table, nothing more) and then trigger "onChangeViewContext" function again, I can get the rows array completely.
Even on the first call when I try to get table's model, I can get the treeModel and its data correctly.
I've tried to refresh bindings, aggregations etc. But no luck.
By the way, I'm using row binding in my xml view like this :
<t:TreeTable id="idSelectElementsTree" rows="{path: 'treeModel>/'}" selectionMode="MultiToggle" enableSelectAll="false"
rowSelectionChange="onSelectElement">
I'm really drowning here so any any help would be appreciated.
Edit : rest of the setSelectedIndexes function :
aViewContext.forEach(function(name) {
sElementName = name;
if (aElements.indexOf(sElementName) !== -1) {
aSelectedIndices.push(aElements.indexOf(sElementName));
}
});
aSelectedIndices.forEach(function(idx) {
if (oTree.getRows()[idx]._bHasChildren) {
oTree.expand(idx);
}
oTree.addSelectionInterval(idx, idx);
});
What could help here is to add an event rowsUpdated="onRowsUpdated" to the table in the XML view. This event is triggered after the table has been loaded and will hence provide you with the data via;
this.getView().byId("sTableId").getRows();
The difference to your approach is that the event would not be triggered by the press of a button but automatically, as the table is rendered. You can then also use this function to trigger another one as per your use case.

Highcharts - get visible series name dynamically

I want to make a function which send dynamically all visible series name in a Highchart instance to a PHP function.
For example, in this chart, I want to get this array : [Salle, PR].
If I click on Internet, the serie become visible and I want to get [Salle, Internet, PR].
To do this, I tried to use legendItemClick event and make a function that check if each serie is visible to add it to an array but I can't figure out how to use the visible option to do this.
Do you have an idea ?
As of now, I don't have much code to share :
plotOptions: {
series: {
events: {
legendItemClick: function(){
}
}
}
}
If you retain the pointer to your chart like this:
var ch = Highcharts.chart(_chart_data_);
Then later you can access the whole chart structure. What you will be interested in is the series array.
ch.series[]
It contains array of all your series. Series with visible attribute set to true are the ones that currently displayed. So,it might be something like this:
var ch = Highcharts.chart(...
plotOptions: {
series: {
events: {
legendItemClick: function(){
ch.series.forEach(function(sr){
if(sr.visible){
console.log(sr.name, "visible!");
}
});
}
}
}
}
...);
However, there is a catch with your approach, that on actual legend click your current action for the legend is not yet processed.so the output you will see is the output for the previous state, before current click.
So for that reason you may try to use setTimeout to get your listing after the event is applied:
events: {
legendItemClick: function(){
setTimeout(
function(){
ch.series.forEach(
function(sr){
if(sr.visible){
console.log(sr.name, "visible!");
}
}
)
},20);
}
}
Try this and check the console log: http://jsfiddle.net/op8142z0/

label inside combobox and conditional multiselect

I am building a pretty combobox with checkboxes and conditional entries. Everything works out alright, except for two features that I cannot figure out how to implement.
1) I would like to move the label inside the combobox, make it shift the values to the right, and appear in a slightly gray color.
2) I would like the value to ignore certain entries (group headers) selected. Those entries are there for functionality only - to select/unselect groups of other entries.
The entire project is in the zip file. You don't need a server, it's a client base app. Just download the archive, unpack, and launch app.html in your browser.
http://filesave.me/file/30586/project-zip.html
And here's a snapshot of what I would like to achieve.
Regarding your second issue, the best way I see is to override combobox onListSelectionChange to filter the values you don't want:
onListSelectionChange: function(list, selectedRecords) {
//Add the following line
selectedRecords = Ext.Array.filter(selectedRecords, function(rec){
return rec.data.parent!=0;
});
//Original code unchanged from here
var me = this,
isMulti = me.multiSelect,
hasRecords = selectedRecords.length > 0;
// Only react to selection if it is not called from setValue, and if our list is
// expanded (ignores changes to the selection model triggered elsewhere)
if (!me.ignoreSelection && me.isExpanded) {
if (!isMulti) {
Ext.defer(me.collapse, 1, me);
}
/*
* Only set the value here if we're in multi selection mode or we have
* a selection. Otherwise setValue will be called with an empty value
* which will cause the change event to fire twice.
*/
if (isMulti || hasRecords) {
me.setValue(selectedRecords, false);
}
if (hasRecords) {
me.fireEvent('select', me, selectedRecords);
}
me.inputEl.focus();
}
},
And change your onBoundlistItemClick to only select and deselect items in the boundlist not to setValue of the combo:
onBoundlistItemClick: function(dataview, record, item, index, e, eOpts) {
var chk = item.className.toString().indexOf('x-boundlist-selected') == -1;
if ( ! record.data.parent) {
var d = dataview.dataSource.data.items;
for (var i in d) {
var s = d[i].data;
if (s.parent == record.data.id) {
if (chk) { // select
dataview.getSelectionModel().select(d[i],true);
} else { // deselect
dataview.getSelectionModel().deselect(d[i]);
}
}
}
}
},
Regarding your first issue, it is easy to add the label using the displayTpl config option. But this will only add the text you need, without any style (grey color, etc). The combo is using a text input, which does not accept html tags. If you don't need the user to type text, than you may want to change the combo basic behavior and use another element instead of the text input.
