I have a TypeCtrl ES6 class angular controller which uses a kendo datagrid directive and has template for grid config options , In the template for the grid, i need to call a method from the TypeCtrl class. I need to attach an onclick or ng-click event to the span within the row of the template. However teh function that needs to be triggered on click belongs to the TypeCtrl class. How can i get the context of TypeCtrl within the databound event of teh kendo grid. I see that "this" points to the kendo grid here,
Here is what i have, please let me know as to how i can access teh controller method within the databound event
//Grid options defined in Class TypeCTrl along with openSub method
class TypeCtrl{
constructor() {}
$onInit() {
this.gridOptions = {
name: 'test',
dataBound: function(e) {
//Find the span and on click , attach the typectrl controller's opensub method
let grid = this
let item = grid.tbody.find('#testClick');
let value = item.innerHTML;
item.on('click', this.openSub(value);
}
columns: [{
field: 'subscriptionName',
hidden: true,
groupHeaderTemplate: function(dataItem) {
let temp;
let sname = dataItem.value;
if (sname) {
temp = '<span id="testClick">' + sname + '</span>';
}
return temp;
}.bind(this)
}, {
field: 'name',//Todo: show icons
title: 'name'
}, {
field: 'version',
title: 'version'
}]
}
}
openSub(name) {
alert('thisis a box');
}
}
TypeCtrl.$inject = ['$scope'];
angular.module('core').controller('TypeCtrl', TypeCtrl);
export default TypeCtrl;
I see that when i click on the span tag, the context of this is lost and opensub method is not called. I ned to get to the opensub method when clicked on the row template , can i do this in the dataBound function??
or any other way s?
The common approach is to build AngularJS app with components. If you create a component that contains your grid, then you'll be able to call openSub() method from the template: ng-click="$ctrl.openSub()". In this case, this in your method will point to the TypeCtrl.

Is there a way to manually trigger the Grid-Event onRowClicked programmatically? If I set a node to selected via
node.setSelected(true);
, the event isn't being triggered... Only if I really click on it, but I need to trigger it programmatically too, as a reaction to a service-call.
Seems pretty simple to me. Just call the onRowClicked function on your gridOptions. Seeing as you already have your node, you should be able to get the row and pass it to your onRowClicked function.
var gridOptions = {
columnDefs: columnDefs,
rowData: rowData,
onRowClicked: function(params)
{
console.log('Row Make: ' + params.data.make);
}
};
function clickRowOne()
{
const node = gridOptions.api.getRowNode(0);
gridOptions.onRowClicked(node);
}

I am using TinyMCE 4 and trying to build a dynamic menu. In order to do this I am building an array of menu items which includes an onclick function. The menu displays, but the onclick function does not work because when building the array, the value I need to pass to the function is out of scope - I believe.
var MenuItems = [{"Id":"1","Name":"MenuItem 1"},{"Id":"2","Name":"MenuItem 2"}];
var Menu = [];
for (var i=0;i<MenuItems.length;i++)
{
Menu.push({
text: MenuItems[i].Name,
onclick: function(){
alert(MenuItems[i].Id);
}
});
}
In the onclick declaration, MenuItems[i].Id is not in scope - I believe.
How can I pass the values to the onclick function.
I am then passing the array to the TinyMCE plugin, but I don't believe this is a problem with TinyMCE, but posting this part in case there is a better way.
tinymce.PluginManager.add('myplugin', function(editor, url) {
editor.addButton('menu', {
text: 'MyMenu',
type: 'menubutton',
icon: false,
menu: Menu
});
});
MenuItems[] won't be available when the callback for myplugin would run.
This would also mean, that once, onclick of any menuItem is called, it would try accessing MenuItems[].
To fix this, once way could be to change the implementation like:
var MenuItems = [{"Id":"1","Name":"MenuItem 1"},{"Id":"2","Name":"MenuItem 2"}];
var Menu = [];
for (var i=0;i<MenuItems.length;i++)
{
const id = MenuItems[i].Id;
Menu.push({
text: MenuItems[i].Name,
onclick: function(){
alert(id);
}
});
}
I want to execute a local method in Ext.Template context.
The method should be a member in the class.
I tried the following code and it doesn't work.
Someone know of can I pass the function member to onClick event?
requires: ['Ext.XTemplate'],
alias : 'widget.countlinkcolumn',
func: 'this.handleFilter'
renderer: function(val,metaData,rec,b,c,d,f){
var categoryId = 3;
var colTemplate = new Ext.Template(
'<div class="drill_down_link grid_cell_link" style="cursor: pointer; float:right" onclick="{on_click}({categoryId})">{text}</div>' +
'</div>');
var tpl = colTemplate.apply({
text: text,
categoryId: categoryId,
on_click: this.func,
});
return tpl;
},
handleFilter: function (categoryId) {
console.log(categoryId);
},
});
Never found an simple solution to this problem... The XTemplate can't directly call ExtJS code from it (it's actually already rendered in the DOM)...
The workaround we found is to render the XTemplate in a View (But you can do it with apply()) then listening to the itemClick event.
In the listener we get the DOM element and we can get some additional data from an attribute (eg: data-categoryId):
xtype: 'view',
listeners: {
itemClick: 'onItemClick',
}
// Additional attribute (data-categoryId) that store the categoryId
tpl: '<div data-categoryId="{categoryId}" class="drill_down_link">{text}</div>'
Then in the listener we can use this additional attribute after we checked that the correct button was clicked (by his class name but you can use other attribute)
onItemClick: function(dataView, record, item, index, e, removeAll){
var me = this,
target = e && e.target,
targetClass = target && target.getAttribute("class");
//Clicked on link (identified by his class name)
var isLink = targetClass && targetClass.indexOf("drill_down_link") >= 0;
if(isLink){
// Get the attribute value we setted in the XTemplate
var categoryId = target.getAttribute('data-categoryId');
}
}
I have a jquery-ui button test-button that has a data attribute.
That button calls a custom widget customWidget that has a callback function fnSaveCallback.
$(".test-button").button({
icons: {
primary: 'icon-test icon-mixed icon-custom'
},
text: false
}).customWidget({
id: "custom-widget",
title: "My custom widget",
fnSaveCallback: function() {
// Need to get the data-test attribute from the "test-button"
}
});
I'm having problems trying to access the the test-button in order to get the value of the data-attribute from the callback function.
Any idea how can i do that? Thanks in advance!
I've found an easy way to handle this adding a class on the click event.
$(".test-button").button({
icons: {
primary: 'icon-test icon-mixed icon-custom'
},
text: false
}).click(function() {
// remove opener class from other test-buttons
$(.test-button.opener).removeClass("opener");
// add opener class to the clicked button
$(this).addClass("opener");
}.customWidget({
id: "custom-widget",
title: "My custom widget",
fnSaveCallback: function() {
// Get the data-test attribute from the "test-button"
$(".test-button.opener").data("test");
}
});
You need to have a reference of the element somewhere.
const test_button = document.getElementById('test-button');
and then in fvSaveCallback:
fnSaveCallback: function() {
// Need to get the data-test attribute from the "test-button"
console.log(test_button.dataset.test);
}
EDIT: After your edit, as far as I understand you are trying to apply that method to all .test-button buttons.
You should only need to get a list of nodes, and iterate through it :)
const test_buttons = document.getElementsByClassName('test-button')
;
for (let i = 0; i < test_buttons.length; i++)
{ const button = test_buttons[i]; //This is the button
// Do with 'button' whatever you want here.
console.log(button.dataset.some_data);
}
I'm using jQuery dataTables to display a table. I need to be able to pass a row selection event on to my Aura component that handles the selection and performs some operations on the data from that row.
In the initialize() function:
initialize: function()
{
$("#mytable tbody").click(function(event)
{
$(mytable.fnSettings().aoData).each(function ()
{
$(this.nTr).removeClass('row_selected');
});
$(event.target.parentNode).addClass('row_selected');
});
mytable = $('#mytable').dataTable();
},
I set up the click handler for the row selection, but how do I get a reference to the enclosing component so I can sandbox.emit() function to issue messages? I can put a reference to the component into the Closure, but that essentially makes this component a singleton and I could never have two instances of the component on the page at the same time.
Is there a standard way, using jQuery selectors or some other method, that I can retrieve a reference to the enclosing component from inside the click() handler?
Edit: I should never try to write code until I have had 32oz of caffine. You can pass a reference to the current component via the click() method itself. Like so:
$("#mytable tbody").click(this, function(event)
{
$(mytable.fnSettings().aoData).each(function ()
{
$(this.nTr).removeClass('row_selected');
});
$(event.target.parentNode).addClass('row_selected');
event.data.sandbox.emit('mychannel', {data: 'stuff'});
});
If I understand your question correctly, you could try something like this
initialize: function () {
var that = this;
$("#mytable tbody").click(function(event) {
//have acces to component as 'that'
});
}
what I used for events is view inside component configuration:
View: {
events: {
'click a[data-question-edit-id]': function (e) {
var button = $(e.currentTarget),
id = button.attr('data-question-edit-id'),
examId = this.component.examModel.get('id');
this.sandbox.router.navigate('/exams/' + examId + '/questions/' + id + '/edit', {trigger: true});
},
'click a[data-question-delete-id]': function (e) {
var button = $(e.currentTarget),
id = button.attr('data-question-delete-id');
this.component.showDeleteConfirmation(id);
}
}
}
