I know from reading the assoc. Google group that there is not currently an event for clicking a specific point when using the marker map (only regionClick is implemented).
But was reading the docs and noticed the event Select which says:
select Fired when the user clicks a visual entity. To learn what has
been selected, call getSelection(). None
and
setSelection() none Selects the specified chart entities. Cancels any
previous selection. Selectable entities are regions with an assigned
value. A region correlates to a row in the data table (column index is
null). For this chart, only one entity can be selected at a time.
Extended description.
Would I be able to use this to get the entry that was clicked?
Example:
data.addRows([
['Rome', 2761477, 1285.31],
['Milan', 1324110, 181.76],
['Naples', 959574, 117.27],
['Turin', 907563, 130.17],
['Palermo', 655875, 158.9],
['Genoa', 607906, 243.60],
['Bologna', 380181, 140.7],
['Florence', 371282, 102.41]
]);
Somehow get that Milan was clicked? How would I do this? Or am I reading this wrong?
Google API for Geomaps: http://code.google.com/apis/chart/interactive/docs/gallery/geochart.html
Google Group stating there is no click event in Marker mode:
https://groups.google.com/forum/?fromgroups#!topic/google-visualization-api/K8uJoes8ZH0
You need call getSelection function when the select event is called. This function returns an array of objects. Each object have row and column attributes (if any). Use the row and the first column (0) to retrieve the label name (Rome, Milan, ...).
Example (http://jsfiddle.net/VtZQh/):
google.visualization.events.addListener(chart, 'select', function() {
var selection = chart.getSelection()[0];
var label = data.getValue(selection.row, 0);
alert(label);
});
Please refer to documentation to know more about getSelection.

Adding hyperlinks to maps was already addressed here :
amcharts drill-down map countries clickable
But I am wondering what I would need to change if I were to instead add clickable hyperlinks to the states or provinces within the countries in the 'drill down to countries' example?
https://www.amcharts.com/demos/drill-down-to-countries/
For instance, if I were to click on China and view the provinces, how would I assign a URL to its most southern province, Guangxi Zhuang, by using both the methods that you mentioned above?
The ID for that territory is "CN-GX", and can be found in this file :
https://github.com/amcharts/amcharts4-geodata/blob/master/dist/es2015/chinaHigh.js
Thanks for your help!
As indicated in the linked answer, you can set a url propertyField for the PolygonSeries so that it can apply the URL from the data provided to the series. You can combine this with the done event handler in the countrySeries (the drilled down map) to populate the series' data with the desired information based on the loaded geodata url. For example:
countrySeries.mapPolygons.template.propertyFields.url = "url";
countrySeries.geodataSource.events.on("done", function(ev) {
worldSeries.hide();
countrySeries.show();
if (ev.target.url.indexOf('china') != -1) {
countrySeries.data = [{
id: "CN-GX",
url: "https://en.wikipedia.org/wiki/Guangxi"
}];
}
});
Obviously you'll want to make this more robust in your application, but you get the idea.
Demo of your Guangxi scenario
I am using amCharts pie chart (v3) and I want to customize the pop up balloon that comes on mouseover on a slice: in addition to routine text like [[value]] [[percent]],
(a) a text that depends on the data item, and
(b) provide different click options to the user depending on data item. Every data row might not have these possibilities in which case the options should not appear.
For example, the pie chart might show wine consumption by country. On hover, I want to provide the user two different click options - one to see consumption by season if available, plus another to see consumption by age group if available.
Is it possible to do so in amCharts? I saw an exit for event clickSlice() here http://docs.amcharts.com/3/javascriptcharts/AmPieChart but nothing on how to modify the balloon text on the fly and add behavior to the balloon that comes on hover.
Will greatly appreciate your help.
For writing dynamic text in the balloon you can also do the folowing:
"graphs": [{
"balloonFunction": function(graphDataItem, graph) {
var value = graphDataItem.values.value;
if (value < 500) {
return value + "<br>(Little)";
} else {
return value + "<br>(A Lot)";
}
}
}],
You can use the following tags: [[title]], [[description]], [[value]] and [[percent]]. says the documentation.
I have used description for a custom field, it works fine.
You can add any custom field to your data provider and then display it in your balloon in the same way as value:
{value:15, title:"slice title", someCustomField:"some custom data"}
and then:
chart.balloonText = "[[someCustomField]]";
I'm using Dojo 1.9 and GridX 1.2. I'd like to detect the event that given row (or cell) has been changed by the user. Then additional action would be done, for example a row would change background color and the "Save" button would be enabled.
I was searching for the examples and in documentation, but I haven't found an example. How to register a listener reacting to edits in the grid, that would give me information what row or what cell has been edited, with the possibility of reading actual value after change?
The event is called 'onApply' and is registered on grid.edit (Module-Edit reference)
The example code to achieve that:
grid.edit.connect(grid.edit, "onApply", function(cell, success) {
var item = cell.row.data()
var id = cell.row.id
console.log('Row with ID '+id+' is modified. New value: '+item)
})
i asked a similar question before however the solution no longer works for my application, i need a button click to create a new row (FailureInstance) in a table (failuretable) and i need it to populate three of the cells with data from fields that are elsewhere filled in. here is my code: form1.failuretable.AddFailureButton::click - (JavaScript, client)
xfa.host.messageBox("Failure Recorded and Added To Table Below. Please Continue Filling Out the Form Until All Failures Have Been Recorded. Then Please Save and Submit the Form.", "Continue/Save/Submit", 3);
if (xfa.host.version < 8) {
xfa.form.recalculate(1);
}
var newRow = failuretable._FailureInstance.addInstance(1);
newRow.FailureCode.rawValue = form1.FailureType.rawValue;
newRow.Location.rawValue = form1.CellLocation.rawValue;
newRow.Comments.rawValue = form1.AdditionalComments.rawValue;
right now this doesn't even create a new row for my table... any help is appreciated!
You should check whether multiple instances for a row are allowed. Select FailureInstance in hierarchy view and then in Object->Binding (if you dont see it go to window menu and select Object) check wheter "Repeat Row for Each Data Item" is selected. If not then select it and your code should work fine.
I advice also to enable JavaScript debugging in your Adobe Reader because it than you should see when error appears and what is it about. Open Reade go to Edit->Preferences->JavaScript and select "Show console on errors and messages". Then you will need to restart Designer.
At design time remember to enable:
Object > Data Binding > Repeat Table For Each Data Item
In code, I believe that lack invoking "instaceManager":
...
var newRow = failuretable.FailureInstance.instanceManager.addInstance(1);
...

I have a working jQuery autocomplete being performed on the text input of a table data element, txtRow1. The text data is remote, from a mysql database, and is returned by JSON as 'value' for the text input. The returned data includes another piece of text, which, via a select event within the autocomplete, is populated to the adjacent table data element tickerRow1.
With help from the SO community, the autocomplete is now live and working on all text input elements of a dynamically created table (so txtRow1 to txtRowN). There is javascript code to create and name the table elements txtRoxN + 1 and tickerRowN + 1.
However, I have a problem with the select event for the id of tickerRowN. Because it changes every time I add a row, I don't know how to call the select event for the specific id of the table data in question.
I have done a lot of searching around but as I am new to this, the only functions I have been able to find manipulate the element data when you know the id already. This id is dynamically created and so I don't know how to build the syntax.
Thankyou for your time.
UPDATE: with huge thanks to JK, the following example works. I now know about jsFiddle and will try to use this for all further questions. The following code works for my dynamic example, but I don't know why. Sigh.
jsFiddle working example
function getRowId(acInput){
//set prefix, get row number
var rowPrefix = 'txtRow';
var rowNum = acInput.attr("id").substring((rowPrefix.length));
return rowNum;
}
$("#txtRow1").autocomplete({
source: states,
minLength: 2,
select: function(event, ui) {
var tickerRow = "#tickerRow" + getRowId($(this));
//set ticker input
$(tickerRow).val(ui.item.label);
}
});
