I have a feature where box can be dragged and dropped into the grey area(Please refer to the stackblitz link)
Once the box is dragged and dropped , the box can only be moved within the grey area by clicking on the pink color of the box.
Resizing functionality has also been added, so the box can be resized.
Before resize directive was added the box can only be moved within grey area but after adding adding the resize directive when we resize, the box starts moving out of the grey area , the issue is the box should not move out of the grey area when resizing is done
Stackblitz link
https://stackblitz.com/edit/angular-kkj1wc?file=src/app/hello.component.html
hello.component.html [ has the box and directives applied on the box ]
{{ box.dis }}
</div>
where the box has (dragStart) output event emitter which is bound to draggable directive([appDroppable + draggable] and for the
move functionality appMovable, appMovableArea directives are there) .And the events are shared aming directives using Droppable.service.ts
The (drop) is an output event emitter applied on grey area using
dropzone[appDropzone] directive
import { Directive, ElementRef, EventEmitter, HostBinding, HostListener,
OnInit, Output, SkipSelf } from '@angular/core';
import { DroppableService } from './droppable.service';
@Directive({
selector: '[appDropzone]',
providers: [DroppableService]
})
export class DropzoneDirective implements OnInit {
@Output() drop = new EventEmitter<PointerEvent>();
@Output() remove = new EventEmitter<PointerEvent>();
private clientRect: ClientRect;
constructor(@SkipSelf() private allDroppableService: DroppableService,
private innerDroppableService: DroppableService,
private element: ElementRef) { }
ngOnInit(): void {
this.allDroppableService.dragStart$.subscribe(() =>
this.onDragStart());
this.allDroppableService.dragEnd$.subscribe(event =>
this.onDragEnd(event));
this.allDroppableService.dragMove$.subscribe(event => {
if (this.isEventInside(event)) {
this.onPointerEnter();
} else {
this.onPointerLeave();
}
});
this.innerDroppableService.dragStart$.subscribe(() =>
this.onInnerDragStart());
this.innerDroppableService.dragEnd$.subscribe(event =>
this.onInnerDragEnd(event));
}
private onPointerEnter(): void {
if (!this.activated) {
return;
}
this.entered = true;
}
private onPointerLeave(): void {
if (!this.activated) {
return;
}
this.entered = false;
}
private onDragStart(): void {
this.clientRect = this.element.nativeElement.getBoundingClientRect();
this.activated = true;
}
private onDragEnd(event: PointerEvent): void {
if (!this.activated) {
return;
}
if (this.entered) {
this.drop.emit(event);
}
}
private onInnerDragStart() {
this.activated = true;
this.entered = true;
}
private onInnerDragEnd(event: PointerEvent) {
if (!this.entered) {
this.remove.emit(event);
}
}
private isEventInside(event: PointerEvent) {
return event.clientX >= this.clientRect.left &&
event.clientX <= this.clientRect.right &&
event.clientY >= this.clientRect.top &&
event.clientY <= this.clientRect.bottom;
}
}
Then on the box (dragStart) output event emitter which is present indraggable directive[appDraggable] which listens for pointerdown events
import { Directive, EventEmitter, HostBinding, HostListener, Output,
ElementRef } from '@angular/core';
@Directive({
selector: '[appDraggable],[appDroppable]'
})
export class DraggableDirective {
@Output() dragStart = new EventEmitter<PointerEvent>();
@Output() dragMove = new EventEmitter<PointerEvent>();
@Output() dragEnd = new EventEmitter<PointerEvent>();
constructor(public element: ElementRef) {}
@HostListener('pointerdown', ['$event'])
onPointerDown(event: PointerEvent): void {
if (event.button !== 0) {
return;
}
this.pointerId = event.pointerId;
this.dragging = true;
this.dragStart.emit(event);
}
@HostListener('document:pointermove', ['$event'])
onPointerMove(event: PointerEvent): void {
if (!this.dragging || event.pointerId !== this.pointerId) {
return;
}
this.dragMove.emit(event);
}
@HostListener('document:pointercancel', ['$event'])
@HostListener('document:pointerup', ['$event'])
onPointerUp(event: PointerEvent): void {
if (!this.dragging || event.pointerId !== this.pointerId) {
return;
}
this.dragging = false;
this.dragEnd.emit(event);
}
}
Movable directive for maintaining move inside the grey area which in
turn uses calculation based from Movable area directive
import { Directive, ElementRef, HostBinding, HostListener, Input } from
'@angular/core';
import { DraggableDirective } from './draggable.directive';
import { DomSanitizer, SafeStyle } from '@angular/platform-browser';
interface Position {
x: number;
y: number;
}
@Directive({
selector: '[appMovable]'
})
export class MovableDirective extends DraggableDirective {
@HostBinding('style.transform') get transform(): SafeStyle {
return this.sanitizer.bypassSecurityTrustStyle(
`translateX(${this.position.x}px) translateY(${this.position.y}px)`
);
}
@HostBinding('class.movable') movable = true;
position: Position = {x: 0, y: 0};
private startPosition: Position;
@Input('appMovableReset') reset = false;
constructor(private sanitizer: DomSanitizer, public element: ElementRef) {
super(element);
}
@HostListener('dragStart', ['$event'])
onDragStart(event: PointerEvent) {
this.startPosition = {
x: event.clientX - this.position.x,
y: event.clientY - this.position.y
}
}
@HostListener('dragMove', ['$event'])
onDragMove(event: PointerEvent) {
this.position.x = event.clientX - this.startPosition.x;
this.position.y = event.clientY - this.startPosition.y;
}
@HostListener('dragEnd', ['$event'])
onDragEnd(event: PointerEvent) {
if (this.reset) {
this.position = {x: 0, y: 0};
}

For some reason button elements have extra “padding” or “height” when compared to other elements with the same value if the value is not fixed but dynamic.
I have verified the issue myself in Chrome and Safari on iOS, and one of my friends verified the issue in Chrome on Android.
A. Fixed value for padding
span, button {
padding: 16px;
}
The height of the button on the right is 1px more, but both elements are otherwise equal according to a console log, which actually seems to be the case.
Here is the codepen.
B. Dynamic value for padding
span, button {
padding: calc(var(--gap) / 2);
}
@media screen and (min-width: 0px) {
html {
--gap: calc(10px + (40 - 10) * (100vw - 0px) / (1200 - 0));
}
}
Clearly the button on the right is much taller than the span element on the left, even though console says they’re basically equal, and the exact same value has been applied to both elements…
Here is the codepen.
Does anybody know what is going on here?
Updates
Applying a line-height: 1.15 and margin: 0 to the button element reduces the discrepancy.
Oddly, console claims the span element is still 1px wider (and 2px taller), even though they’re effectively the exact same width if you overlay the two elements.
The text of the span element is 1px or 2px lower than the text in the button element, which makes sense because the span is 1px or 2px taller.
button {
...
margin: 0;
line-height: 1.15;
}
Here is the codepen.
I would just add a pixel or two to the button height, but unfortunately the height of many elements on my website is determined by a combination of a dynamic font-size and padding. And I’d rather not have to constantly run a bunch of JS in the background to dynamically calculate the height for every element on the fly.

I’m using WCFStorm in order to debug a very simple SOAP endpoint:
http://www.dneonline.com/calculator.asmx?WSDL
such endpoint can be used in order to request the 4 basic arithmetic calculations and retrieve a response: here in the example I’m requesting the numbers 3 and 5 and I receive as response 8, all good!
I now want to create an HTML page that can do the same without using WCFStorm. Here is my code:
<html>
<head>
<title>Calling Web Service from jQuery</title>
http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js
$(document).ready(function() {
$("#btnCallWebService").click(function(event) {
var wsUrl = "http://www.dneonline.com/calculator.asmx?WSDL";
var soapRequest = ' ' + $("#intA").val() + ' ' + $("#intB").val() + ' ';
alert(soapRequest)
$.ajax({
type: "POST",
url: wsUrl,
contentType: "text/xml",
dataType: "xml",
data: soapRequest,
success: processSuccess,
error: processError
});
});
});
function processSuccess(data, status, req) {
alert('success');
if (status == "success")
$("#response").text($(req.responseXML).find("Int32").text());
alert(req.responseXML);
}
function processError(data, status, req) {
alert('err' + data.state);
//alert(req.responseText + " " + status);
}
</head>
<body>
<h3>
Calling Web Services with jQuery/AJAX
</h3>
Enter the numbers:
<input id="intA" type="string" />
<input id="intB" type="string" />
<input id="btnCallWebService" value="Call web service" type="button" />
</body>
</html>
But unfortunately I can only receive an: errundefined.
Where am I wrong?

- in driveFiles I am getting multiple file names.
– for each attachment I need to attach pdf or word or jpg icon
– so I used substr and lastIndexOf got the file formats.
– now using if conditions I am able to disable icon for one files.
– if I test for more than one files, its not checking for second if.
– I think the problem is due to the return statement in first if.
– can you tell me how to fix it for multiple files.
– providing my code snippet below.
<!-- language-all: lang-or-tag-here -->
{this.props.driveFiles.length > 0
? this.props.driveFiles.map(_driveFileKey => {
var driveFormat = _driveFileKey.name.substr(
_driveFileKey.name.lastIndexOf(".") + 1
);
console.log("filename--->", driveFormat);
if (driveFormat === "pdf") {
return (
{" "}
{_driveFileKey.name}
);
} else if (driveFormat === "doc") {
return (
{" "}
{_driveFileKey.name}
);
} else if (driveFormat === "jpg") {
return (
{" "}
{_driveFileKey.name}
);
}
//return {_driveFileKey.name}

I have a system that generates a list of nodes which may or may not have additional elements between the nodes. I want to visualize this list horizontally with lines connecting the nodes as shown in the example below.
The content between two nodes is variable and can even contain more complex elements like images and tables. The nodes themselves are labeled with only text (Point A, Point B, etc.).
Code & What I have tried so far
In my first attempt at trying to visualize the nodes I simply used a vertical list with the :before and :after CSS pseudo-elements to draw the lines between the nodes. I am however having difficulty translating this approach to a horizontal list.
Vertical approach:
h1, h2 {
margin: 0;
padding: 0;
}
ul {
list-style-type: none;
text-align: left;
}
ul li {
padding: 0 0 20px 50px;
position: relative;
margin: 0;
}
ul li:after {
display: inline-block;
position: absolute;
top: 0;
left: 0;
font-family: "Font Awesome 5 Free";
font-weight: 300;
content: "f111";
height: 24px;
width: 24px;
text-align: center;
line-height: 24px;
background: #fff;
}
ul li:before {
position: absolute;
left: 11px;
top: 0;
content: "";
height: 100%;
width: 0;
border-left: 2px solid #000;
}
ul li:last-of-type:before {
border: none;
}
<link href="https://use.fontawesome.com/releases/v5.5.0/css/all.css" rel="stylesheet"/>
<ul>
<li>
<h2>Node A</h2>
Content
</li>
<li>
<h2>Node B</h2>
Content
</li>
<li>
<h2>Node C</h2>
</li>
</ul>
Horizontal approach:
h1, h2 {
margin: 0;
padding: 0;
}
ul {
list-style-type: none;
}
ul li {
display: inline-block;
position: relative;
border-bottom: 2px solid #000;
}
ul li:after {
position: absolute;
top: 0;
left: 0;
font-family: "Font Awesome 5 Free";
font-weight: 300;
content: "f111";
height: 24px;
width: 24px;
background: #fff;
}
<link href="https://use.fontawesome.com/releases/v5.5.0/css/all.css" rel="stylesheet"/>
<ul>
<li>
<h2>Node A</h2>
Content
</li>
<li>
<h2>Node B</h2>
Content
</li>
<li>
<h2>Node C</h2>
Content
</li>
</ul>
I simply don’t really know how to align all of this properly. How can I achieve what is depicted in the example image above?
Constraints
- I only support the latest version of modern browsers, so no compatibility is required for ancient browsers;
- I prefer an HTML(5) and CSS only approach
