Highcharts Renderer Button ID

I've rendered the buttons to multiple Highcharts, but I need to know which button I click..
Example
API

Inside a callback this refers to the clicked button. You can also set its id if you use attr() method.
var custombutton = charts[i].renderer.button('button', 450, 10, function() {
// not working
alert(this.element.id);
}, null, hoverState, pressedState).attr({
id: 'button-' + i
}).add();

javascript click event working only for first element in WebGrid MVC

I have a webgrid that gets populated on page load. In this grid I have an element that has a javascript event handled when it is clicked. Here I simply intend to sent the user to an external site. I also have this tied to a controller. Both are working for the first element. However, when it comes to anything after the first element in the list the javascript does not get called.
WebGrid:
#grid.GetHtml(tableStyle: "table table-striped table-bordered",
headerStyle: "thead-default",
columns: grid.Columns(
grid.Column("post_tran_a", Model.year_a, canSort: false, format: (item) =>
new HtmlString(Html.CheckBox("post_tran_a", (bool)item.post_tran_a.is_reviewed, new { disabled = "disabled" })
+ " " +
Html.ActionLink((string)item.post_tran_a.month, "PostTransmission", Model.controller, new { report_id = item.post_tran_a.report_id, link = item.post_tran_a.link }, new { #id = "external-link", data_url=Url.Action() })
))))
Javascript:
$("#external-link").click(function () {
var url = $("#external-link").attr("data-url");
alert(url);
});
If this approach won't work I'm open to alternative solutions.

Simplest way in your particular case might work like
$("table a").click(function () {
// you need here 'this' it is available by default
// and it points to the object on which click is called
var url = $(this).attr("data-url");
alert(url);
});
But above is too general. It will fail if you have tables having other links a where you do not want to fire the even so better approach is following
Id only works for one element. For a set of elements (e.g. multiple links). You need to use the class and access them by class as well.
I replaced your id with class and accessed it with that name as well.
grid.GetHtml(tableStyle: "table table-striped table-bordered",
headerStyle: "thead-default",
columns: grid.Columns(
grid.Column("post_tran_a", Model.year_a, canSort: false, format: (item) =>
new HtmlString(Html.CheckBox("post_tran_a",
(bool)item.post_tran_a.is_reviewed, new { disabled = "disabled" })
+ " " +
Html.ActionLink((string)item.post_tran_a.month, "PostTransmission",
Model.controller, new { report_id = item.post_tran_a.report_id, link = item.post_tran_a.link },
// See following carefully
new { #class="someuniquecalssname" data_url=Url.Action() })))))
Now the javascript will work fine
$(".someuniquecalssname").click(function () {
var url = $(this).attr("data-url");
alert(url);
});
If you are not willing to add class attribute then, Creating Unique Ids like ex-link1, ex-link2 could be possible in many cases. But they are useless for an event like above

You are using id to select the element, an id must be unique on the page. use either a class or unique ids when setting them in your code #id = "external-link--xxx"
You could also use a different selector in your jquery selector
$("#yourtableid a").click(function () {
var url = $("#external-link").attr("data-url");
alert(url);
});

Saving several tab panels with one button

I have three seperate tab panels with each being a table in my database. What i'm trying to do is that on a click of a button is save the content of all the three tabs in the database at the same time. I managed to get the PK "Aid" of the current active tab, however when i try to access the second inactive tab B with window.frames["frm_B"] and alerting the result, i'm getting undefined. Any help would be much appreciated.
tabPanel = Ext.create('Ext.tab.Panel', {
region: 'center',
activeTab: 0,
autoScroll: true,
tbar: [{
xtype: 'button',
text: 'Save',
handler:function(){saveForm("frm_A", save);}
}],
items: [
{
id:"panel_A",
html: "<iframe src= '"+A_url +"' width='100%' height='100%' id='frm_A' name='frm_A' frameborder=0 />",
},{
id:"panel_B",
html: "<iframe src='"+B_url+"' width='100%' height='100%' id='frm_B' name='frm_B' frameborder=0 />",
},{
id:"panel_C",
html: "<iframe src= '"+C_url+"' width='100%' height='100%' id='frm_C' name='frm_C' frameborder=0 />",
}]
});
viewport = new Ext.Viewport({
layout:'border',
items:[tabPanel]
});
function save(record){
var Aid = record.getKey();
var doc = window.frames["frm_B"];
alert(doc);
try {
doc.RECORD.getField("A_ID").setRealValue(Aid);
doc.RECORD.update(closeAndRefresh, viewExtError);
}
catch(e){
showError(e);
}
}

I guess your problem is that your <iframe name='frm_B'> is not rendered (added to DOM) when you try to get it with window.frames["frm_B"].
When you create tab panel with Ext.create('Ext.tab.Panel', {}); you just create JS object, not all of its items: [] added to DOM immediatelly.
A Container's child Components are rendered by that Container's layout
manager when the Container is first rendered.
For example tabpanel tabs added to DOM when you first time open that tab.
Fiddle to illustrate it
Solution for your question depends on your code actually, but as workaround you can use .render() method of tab panel child panels...

Extjs 5.1 Dynamic addition of container to panel

What i am trying to do is dynamically add container to panel on click of button.
1st instance of container gets added and can be seen in the panel.items.length
2nd instance onwards the panel.items.length doesn't change. but the panel can be seen in dom and on screen.
Just wanted to know why the panel.items.length is not increasing. Is it a bug?
Fiddler link https://fiddle.sencha.com/#fiddle/p3u
Check for the line :
console.log(qitems);
below debugger; it is set to questionsblock.items.length that i am talking about.

Remove the itemId from QuestionTemplate and remove renderTo from the new instance.
Your click handler should look like this:
listeners: {
'click': function(button) {
var questionPanel = button.up('form').down('#questionsblock'),
qitems = questionPanel.items.length,
questiontemplate = Ext.create('QuestionTemplate', {
qid: qitems,
questiontype: 'text'
});
console.log(qitems);
questionPanel.add(questiontemplate);
questionPanel.doLayout();
}
}

Backbone - Access a View's $el.attr outside of the ItemView

I have the following ItemView (there is no model associated with the view, it's a very basic "form" which has a submit or cancel and a single input field):
App.BasicForm = Backbone.Marionette.ItemView.extend({
template: "build/templates/basic-form.html",
tagName: "div",
attributes: {
id: "some-id",
style: "display: none;"
},
events: {
"click button#bf-submit": "bfSubmit",
"click button#bf-close": "bfClose"
},
bfSubmit: function() {
var bfInputField= document.getElementById('bfSomeData').value;
},
bfClose: function() {
this.$el.hide();
}
});
So by default, this view is hidden (but is instantiated when App starts).
I want to have a button which, when clicked, simply changes the attribute style display to block.
I can do this easily like this:
document.getElementById('bfBasicFormDiv').style.display = "block";
However, I'd rather call the view's $el.attr and edit it there, something along the lines of:
App.BasicForm.$el.attr({style: "display: block;"});
However, this returns an undefined, and I can see no way of retrieving the attribute of the View (it's easy with models using .get()) but that doesn't hold for a view.
Thank you for any advice.
Gary

App.BasicForm is not an instance, so it doesn't hold an element. You need to initialize it and you will be able to reference the element with $el:
var basicForm = new App.BasicForm({
el: document.getElementById('bfBasicFormDiv')
});
basicForm.$el.css({display: "block"});
