Currently using the infinite search method that Algolia supplies through their instantSearch.js.
The following scenario is happening:
Search for an item
Refine the list
Load more pages up to page 5
Scroll back to the top and change refinement
Nothing happens
By the looks of it - it's appending the results of the new refinement to the results that are already there. I'm looking to make it resent the results, not sure if this is a bug with instant search itself?
search.addWidget(
instantsearch.widgets.numericRefinementList({
container: '#price',
attributeName: 'salePrice',
options: [
{name: 'All'},
{end: 20, name: 'less than 20'},
{end: 50, name: 'less than 50'},
{start: 50, end: 100, name: 'between 50 and 100'},
{start: 100, end: 300, name: 'Expensive'},
{start: 300, name: 'Very Expensive'}
],
templates: {
header: 'Price'
}
})
);
And the infinite search code:
search.addWidget(
instantsearch.widgets.infiniteHits({
container: '#infinite-hits-container',
templates: {
empty: 'No results',
item: hitTemplate
},
hitsPerPage: 3
})
);
This issues is fixed in 1.11.15 (instructions for getting the new version is here)

We are using highcharts to plot multiple charts on a single HTML page.
However one/some of the chart throw highchart error and we like to capture those error and show different error to user.
For this highcharts do provide custom error handler. But this custom error handler does not provide information about specific chart throwing that error.
Here that JS Fiddle provided by highcharts, which works fine for a chart :
Highcharts.error = function (code, true) {
// See
https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
Highcharts.charts[0].renderer
.text('Chart error ' + code)
.attr({
fill: 'red',
zIndex: 20
})
.add()
.align({
align: 'center',
verticalAlign: 'middle'
}, null, 'plotBox');
};
http://jsfiddle.net/gh/get/library/pure/highslide-software/highcharts.com/tree/master/samples/highcharts/chart/highcharts-error/
Any idea how can I use this custom error handler per chart?
I'm using new Highcharts.Charts(options) to create new chart, but don't see way to specify error handler per chart.
Additional info: Charts are refreshed/appended using data through APIs. User that configures chart also configures refresh interval and query to use for chart.
Error handling in HighCharts does not make much sense. It would make more sense to pass the chart instance to Highcharts.error (like Kamil Kulig wrote) or to have an error event in chart.events. Anyways
here is a solution I came up with:
Create an array of errors:
var chartErrors = [];
Create an error handler which will push errors into the chartErrors. Error objects I'm making look like this: {"chartIndex": <chart index>, "errorCode": <error code>}. All charts are added to the Highcharts.charts array when they are created so we can use Highcharts.charts.length - 1 for the chartIndex.
Highcharts.error = function (code) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
chartErrors.push({"chartIndex": Highcharts.charts.length - 1, "errorCode":code});
};
After initiating all charts we will have an array of errors. We can call forEach on this array and handle errors the way we want.
chartErrors.forEach(function(c) {
Highcharts.charts[c.chartIndex].renderer
.text('Chart error ' + c.errorCode)
.attr({
fill: 'red',
zIndex: 20
})
.add()
.align({
align: 'center',
verticalAlign: 'middle'
}, null, 'plotBox');
});
Working example:
Note: I've wrapped the code in a self invoking function to prevent leaking variables to global scope.
(function() {
var chartErrors = [];
Highcharts.error = function (code) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
chartErrors.push({"chartIndex": Highcharts.charts.length - 1, "errorCode":code});
};

Highcharts error function is not adjusted to have a chart context as an argument, because it can be executed in different contexts too.
For example: error number 16 occurs when Highcharts/Highstock is loaded second time in the same page. It has nothing to do with the chart, because it depends on script importing only.
The workaround I found requires some searching and and a little bit of coding.
Refer to this live demo: http://jsfiddle.net/kkulig/a8nun9aL/
I found the place in the code responsible for throwing the error 10 (the one you used in your example). I overwrote this function (see this doc page for more information about overwriting in Highcharts: https://www.highcharts.com/docs/extending-highcharts/extending-highcharts) and added a chart variable (from Highcharts.Axis.prototype.setTickInterval scope) as the third argument:
if (
axis.positiveValuesOnly &&
!secondPass &&
Math.min(axis.min, pick(axis.dataMin, axis.min)) <= 0
) { // #978
H.error(10, 1, chart); // Can't plot negative values on log axis // MODIFIED LINE
}
It should be done for all errors you want to custom handle.
Now it can be used in custom Highcharts.error function:
Highcharts.error = function(code, stop, chart) {
// See https://github.com/highcharts/highcharts/blob/master/errors/errors.xml
// for error id's
Highcharts.charts[0].renderer
.text('Chart error ' + code + " on chart titled: " + chart.title.textStr)
(...)
You can add your own property in chart constructor options and find it in chart.options object.
I need to fill PDF form, Which contains radio buttons too. I tried to fill it with perl, CAM::PDF module and with node, pdf-fill-form module.
In node, the radio's value is always undefined:
{
name: 'Op1',
page: 14,
value: undefined,
id: 983128,
type: 'radio'
}
In perl, the object's value looks like this (if the first option is checked is S, second: XL, third: 2XL etc):
'V'=> bless({
'gennum'=>0,
'value'=>'S',
'type'=>'label',
'objnum'=>988
},
'CAM: : PDF: : Node')
If I change the S to XL, nothing happens in the PDF.
Has somebody any idea, How to fill the radio box?
You can do with node js npm pdf-fill-form module.
let say you are trying to set gender:
your radio button must be formed this way.
{ name: 'gender',
page: 0,
value: false,
id: 65558,
caption: 'male',
type: 'radio' },
{ name: 'gender',
page: 0,
value: false,
id: 65559,
caption: 'female',
type: 'radio' }
Here caption is the important one.
if you trying to set gender is male means just do this
{ gender: 'male'}
I am using this library: mobiscroll.custom-2.5.0.min.js. How do I set limits to deny users' selecting past dates?
My code:
xtype:'panel',
layout:'hbox',
width: (screenWidth-(84+24+55))/2,
cls: 'paymentsSectionDetailsDate',
items:[{
xtype:'panel',
html:'<div class="paymentsSectionDetailsDateLabel" >'+txt_PayOn+'</div>',
width: 80
},{
xtype: 'button',
text:txt_select_date,
name: 'BillPayDetailsForm_date',
id:'BillPayDetailsForm_date',
cls: 'paymentsSectionDetailsDateTextButt',
listeners:{
tap : function()
{
inputNumber=4;
$('#dateIos').fadeIn("slow");
}
}
}]
I am not familiar with mobiscroll, could you use a datepicker? It has 'yearFrom' and 'yearTo' configuration options. You might be able to use a listener to get the data into mobiscroll.
I am very confused by the Sencha documentation for ExtJS. The documentation begins with a Getting Started guide which highlights and illustrates the importance on a suitable structure for the classes and source code of your application. But the provided examples then break all the conventions laid down by the Getting Started guide. Instead of code being broken down into appropriate Model, Store, View, etc. class files the examples are provided as a single file with example source code which is not easily re-usable in separate source files.
I started by following the Portal example (http://docs.sencha.com/ext-js/4-1/#!/example/portal/portal.html) as this is the sort of application I want to create. I wanted to enhance the Portal example and add in a screen which would display a grid and use a RESTful web service as the data backend. I have created the backend I just want to create the front-end. So I looked at the RESTful example (http://docs.sencha.com/ext-js/4-1/#!/example/restful/restful.html)
I have tried to copy the RESTful example into the recommended pattern of seperate classes e.g. Model, Store, View:
Model:
Ext.define('MyLodge.model.Member', {
extend: 'Ext.data.Model',
fields: [
{name: 'name', type: 'string'},
{name: 'email', type: 'string'},
{name: 'href', type: 'string'}
]
});
Store:
Ext.require('MyLodge.model.Member');
Ext.define('MyLodge.store.Members', {
autoLoad: true,
autoSync: true,
model: 'MyLodge.model.Member',
proxy: {
type: 'rest',
url: 'http://localhost:8888/rest/memberapi/members' ,
reader: {
type: 'json',
root: 'data'
},
writer: {
type: 'json'
}
},
listeners: {
write: function(store, operation){
var record = operation.getRecords()[0],
name = Ext.String.capitalize(operation.action),
verb;
if (name == 'Destroy' ) {
record = operation.records[0];
verb = 'Destroyed';
} else {
verb = name + 'd';
}
Ext.example.msg(name, Ext.String.format( "{0} member: {1}", verb, record.getId()));
}
}
});
View:
Ext.define('MyLodge.view.content.MemberGrid', {
extend: 'Ext.grid.Panel',
alias: 'widget.membergrid',
initComponent: function(){
var store = Ext.create('MyLodge.store.Members' );
Ext.apply( this, {
height: this.height,
store: store,
stripeRows: true,
columnLines: true,
columns: [{
id : 'name',
text : 'Name',
flex: 1,
sortable : true,
dataIndex: 'name'
},{
text : 'E-Mail',
width : 150,
sortable : true,
dataIndex: 'email'
},{
text : 'Href',
width : 200,
sortable : true,
dataIndex: 'href'
}],
dockedItems: [{
xtype: 'toolbar',
items: [{
text: 'Add',
iconCls: 'icon-add',
handler: function(){
// empty record
store.insert(0, new MyLodge.model.Member());
rowEditing.startEdit(0, 0);
}
}, '-', {
itemId: 'delete',
text: 'Delete',
iconCls: 'icon-delete',
disabled: true,
handler: function(){
var selection = grid.getView().getSelectionModel().getSelection()[0];
if (selection) {
store.remove(selection);
}
}
}]
}]
});
this.callParent(arguments);
}
});
But I am not sure where to put the code to control the grid row selection and enable the Delete button:
grid.getSelectionModel().on('selectionchange', function(selModel, selections){
grid.down('#delete').setDisabled(selections.length === 0);
});
Also when I press the Add button I get the following error:
Uncaught TypeError: Object [object Object] has no method 'insert'.
Any help would be appreciated.
You are having scoping issues. Basically the variable store is defined only in the initComponent function and therefore of local function scope.
Your handler function has it's own scope. It is firing in the scope of the toolbar button. So if you say this in the handler it would refer to the button. Hence you can say this.up('panel').store - and that gives you the correct reference to the store backing your grid panel.
Another advice is not to implement everything at once. Write a little bit to see if it works and then add to it little by little.
RE: the docs examples, I agree that it's frustrating, but there's not many options. Having a fully-MVC-style implementation of each example would not only be onerous to produce, but would also probably make point of the example get lost in the structure.
RE: your question about the where to "put" the code to control the grid, I would recommend setting up a controller with listeners for the events on the grid in the control() section. This will let you decouple the handling of the events that are fired by your grid from the view itself.
I'm using ExtJS3 and i want to put this chart into a panel with a dynamic store
http://dev.sencha.com/deploy/ext-3.4.0/examples/chart/pie-chart.html
I tried to include this chart into my panel code but it didn't work.
Does anybody has a solution or an example for a chart included into a panel in ExtJS3
Thank you
I used your example to generate the chart using a dynamic store:
Ext.chart.Chart.CHART_URL = 'http://dev.sencha.com/deploy/ext-3.4.0/resources/charts.swf';
Ext.onReady(function(){
var store = new Ext.data.JsonStore({
url: "sample_data.php",
root: 'results',
fields: [
{name: 'season'},
{name: 'total'}
]
});
new Ext.Panel({
width: 400,
height: 400,
title: 'Pie Chart with Legend - Favorite Season',
renderTo: 'container',
items: {
store: store,
xtype: 'piechart',
dataField: 'total',
categoryField: 'season',
//extra styles get applied to the chart defaults
extraStyle:
{
legend:
{
display: 'bottom',
padding: 5,
font:
{
family: 'Tahoma',
size: 13
}
}
}
}
});
});
where http://dev.sencha.com/deploy/ext-3.4.0/resources/charts.swf is the target where you can find the chart and sample_data.php returns the following json:
{"results":[
{"total":"150","season":"Summer"},
{"total":"245","season":"Fall"},
{"total":"117","season":"Winter"},
{"total":"184","season":"spring"}
]}
Note: This should normally be set to a local resource.
Hope this helps.
