I need to use a text-box (multiline) in my application. It need to grow as the user inputs text into it. I want that textbox to grow without any scrollbars. I tried allow=resize:null but it just prevents textbox from being stretched.All i want is a textbox as we see in facebook comment /share area which grows simply without any scrollbars on sides. I hope i have neatly explained it.
You can use something like this: (Source: Expandable or Auto-Resize TextBox Height by Colt Kwong)
<asp:TextBox ID="txtMsg" runat="server" TextMode="MultiLine"
style="overflow:hidden" onkeyup="AutoExpand(this, event)" Rows="2" />
using this javascript:
function AutoExpand(txtBox, event)
{
if (event.keyCode == "13" || event.keyCode == "8") {
var therows = 0
var thetext = document.getElementById(txtBox.id).value;
var newtext = thetext.split("\n");
therows += newtext.length
document.getElementById(txtBox.id).rows = therows;
return false;
}
}
Or if you like jquery you should take a look at the jQuery autoResize Plugin.
A plugin for jQuery which changes the dimensions of input elements to
suit the amount of data entered. It operates on textarea,
input[type=text] and input[type=password] elements.
Usage is as follows:
$('textarea#foo').autoResize();
You can pass options:
$('textarea#foo').autoResize({
maxHeight: 200,
minHeight: 100
});

I have lost a day on this so far. I have a legend that will obscure a large part of my (AngualrJs) leaflet map, so I don't want it to be permanently visible.
I guess that means a tooltip, although a clickable button might also be acceptable (downside: requires a click to open & one to close).
There are many, many, many attempts to answer this out there, and even a Leaflet legend plugin, which would be ideal, but won't work for me, probably because of the versions of angualrJs or Leaflet used.
Most of the solutions I found seem to use HML & CSS to position a button over the map, but I would be happier with something that is a part of the map.
This question has an answer that actually works. BUT, if I put even the simplest HTML in it, it gets rendered as plain text. E.g <h``>Legend</h1>.
What is the simplest way to show a tooltip on a Leaflet control with interpreted HTML? Failing that a pop-up window?
The legend cannto be permanently displayed as it would obscure the map, and the map must fill the window.
title can't be styled because every browser display it different and has no style functions. Also it should only a one liner.
You can create your own Tooltip which is only visible if the mouse is over the control.
L.CustomControl = L.Control.extend({
options: {
position: 'topright'
//control position - allowed: 'topleft', 'topright', 'bottomleft', 'bottomright'
},
onAdd: function (map) {
var container = L.DomUtil.create('div', 'leaflet-bar leaflet-control');
container.title = "Plain Text Title";
var button = L.DomUtil.create('a', '', container);
button.innerHTML = '<img src="https://cdn4.iconfinder.com/data/icons/evil-icons-user-interface/64/location-512.png" width="100%"/>';
L.DomEvent.disableClickPropagation(button);
L.DomEvent.on(button, 'click', this._click,this);
L.DomEvent.on(button, 'mouseover', this._mouseover,this);
L.DomEvent.on(button, 'mouseout', this._mouseout,this);
var hiddenContainer = L.DomUtil.create('div', 'leaflet-bar leaflet-control',container);
hiddenContainer.style.position = "absolute";
hiddenContainer.style.right = "32px";
hiddenContainer.style.width = "100px";
hiddenContainer.style.height = "100%";
hiddenContainer.style.top = "-2px";
hiddenContainer.style.margin = "0";
hiddenContainer.style.background = "#fff";
hiddenContainer.style.display = "none";
L.DomEvent.on(hiddenContainer, 'mouseover', this._mouseover,this);
L.DomEvent.on(hiddenContainer, 'mouseout', this._mouseout,this);
L.DomEvent.disableClickPropagation(hiddenContainer);
this.hiddenContainer = hiddenContainer;
return container;
},
_click : function () {
},
_mouseover : function () {
this.hiddenContainer.style.display ="block";
},
_mouseout : function () {
this.hiddenContainer.style.display ="none";
},
setContent: function(text){
this.hiddenContainer.innerHTML = text;
}
});
var control = new L.CustomControl().addTo(map)
control.setContent('<span style="color: red">TEST</span>')

You need to style it with CSS by your self
I have issue with rendering inside component. I would like to emit data from another component and send to another component, data was emitted, but the problem is when I create the element with Renderer2, sometimes it's working, but sometimes not. Probably it's a problem with rendering style element in a component?
toolbar.state.service.ts
My service method for emitting data
private globalStyles = new BehaviorSubject<string>('');
formDesign(data: any) {
this.globalStyles.next(data);
}
aside.component.ts
Here I emit data from Reactive Form control and send to another component.
// Height
this.formGlobal.controls['height'].valueChanges
.pipe(debounceTime(500))
.pipe(distinctUntilChanged())
.pipe(takeUntil(this.destroy$))
.subscribe(height => {
this.formGlobal.controls['height'].setValue(height);
this.formGlobal.updateValueAndValidity();
this.showDataCriteria = {
width: this.formGlobal.controls['width'].value + 'px',
height: height + 'px'
};
this.toolbarStatus.formDesign(this.showDataCriteria);
});
builder.component.ts
Here I'm getting data from aside.component.ts and it received!
/**
* Generate CSS
*/
generateCss() {
let basicStyles = ' ';
let newStyle: HTMLElement;
let style: HTMLElement = this.document.getElementById('custom-class');
style
? (newStyle = style)
: (newStyle = this.renderer.createElement('style'));
this.renderer.setAttribute(newStyle, 'id', 'custom-class');
let completeStyleFields = '';
this.customStyle.global

: (basicStyles += '');
console.log(basicStyles);
this.customStyle.sections.forEach(element => {
completeStyleFields += `#${element.id} {${element.textProps}}`;
});
basicStyles += completeStyleFields;
const text = (this.document.textContent = basicStyles);
newStyle.innerText = text;
this.renderer.appendChild(this.dndComponent.nativeElement, newStyle);
}
The Main problem is after style element was created, and I'm seeing the element in the DOM, styles not accepting! Sometimes accepting, and sometimes not. What should I do? How manipulate reload page probably to inject component and styles element?
Short UPD:
After all, I'm seeing #4152ae54-8a9d-49d5-a33d-62dfbbd35890 {height:600px; width:812px; }
But styles not accepted to the elements!
CSS can't render if the first numeric letter (#4152ae54-8a9d-49d5-a33d-62dfbbd35890). That’s because even though HTML5 is quite happy for an ID to start with a number, CSS is not. CSS simply doesn’t allow selectors to begin with a number. The relevant part of the specification states.
The question is simple but i'm not able to make a script by myself for what i need...
I am actually using a script ( fullpage.js ) who toggle some classes into a container ( in my case switching from fp-viewing-1 to fp-viewing-x ) when you scroll down/up between sections.
I need to make a script that listen from this container and toggle a new class into a div ONLY when a class ( in my case fp-viewing-3 ) is added to this container ( from the fullpage.js script of course ).
Any way to make it?
I need to make a script that listen from this container
That's not the way to go for it.
If you want to use the status class, then just create a new class based on the previous ones as explained in this fullpage.js tutorial.
Create a conditional CSS class that will only get applied when its parent class matches your requirement.
Something like this, for example, would only apply the red color to element with myClass when you are in section 1 slide 0.
.fp-viewing-1-0 .myClass{
color: red;
}
Having:
<div id="fullpage">
<div class="section"></div>
<div class="section myClass"></div>
<div class="section"></div>
<div>
If for some other reason (use of plugins etc) you really need to add the class dynamically, then go for fullpage.js callbacks onLeave or afterLoad:
$('#fullpage').fullpage({
onLeave: function(index, nextIndex, direction){
var destination = $('.section').eq(nextIndex - 1);
destination.find('.my-element').addClass('myClass');
}
});
This is the solution to my problem.
Fullpage works as intended except for section 2.
Section 2 will be usable only scrolling down, the script ignore it when scrolling up.
$(document).ready(function() {
$('#application').fullpage({
onLeave: function(index, nextIndex, direction){
var destinationToIgnore = $('.fp-section').hasClass('ignore');
if(destinationToIgnore && direction =='up'){
var destination = nextIndex = 1
$.fn.fullpage.moveTo(destination);
}
},
afterLoad: function(anchorLink, index){
var loadedSection = $(this);
if(index !== 1){
$('.section-intro').removeClass('ignore');
}
if(index == 3){
$('.section-intro').addClass('ignore');
}
}
});
});
How can I drop items (like image, or other object from other canvas) into canvas which is managed by fabricjs? I have found many examples how to move items inside canvas but I would like to drag and drop item from outer element into canvas.
Since you asked for an example and I haven't tried it out myself yet, here goes:
Example Fiddle
Markup
<div id="images">
<img draggable="true" src="http://i.imgur.com/8rmMZI3.jpg" width="250" height="250"></img>
<img draggable="true" src="http://i.imgur.com/q9aLMza.png" width="252" height="295"></img>
<img draggable="true" src="http://i.imgur.com/wMU4SFn.jpg" width="238" height="319"></img>
</div>
<div id="canvas-container">
<canvas id="canvas" width="800" height="600"></canvas>
</div>
JS Breakdown
1. Fabric.canvas instance
First we want our canvas, of course:
var canvas = new fabric.Canvas('c');
2. Feature Detection (optional)
Not sure this is necessary, since the fact that you have a canvas makes it very likely that the browser has Drag and Drop as well. Were you to use it, you can do so like this, using Modernizr:
if (Modernizr.draganddrop) {
// Browser supports HTML5 DnD.
// Bind the event listeners for the image elements
// Bind the event listeners for the canvas
} else {
// Replace with a fallback to a library solution.
alert("This browser doesn't support the HTML5 Drag and Drop API.");
}
3. Events
Again, unlike the source article I below, the source and target elements are different (in that articles's example, you just move divs around within the same parent container), so I failed to notice that some of the events are meant for the element being dragged, but most are bound to the element into which you are dropping.
NOTE: I know this is technically a question about Fabric.js, but it's really kind of a question about Drag and Drop in the context of adding objects to a <canvas> with Fabric.js, which is why I'm going a bit more in depth about the DnD stuff now.
For the <img>
dragstart (I added a class here to lower the opacity)
dragend (and removed that class here)
For #canvas-container:
dragenter (added a class to give the canvas container that nifty dotted line)
dragover: Here you can set the event.dataTransfer.dropEffect property to show one of the native cursor types. The default would be 'move' here, but I set it to 'copy' since I don't actually remove the <img> element (in fact in the fiddle you can, for example create several McClures).
dragleave (removed the dotted line here)
drop: The handler for this event creates and adds the fabric.Image object (see the fiddle).
if (Modernizr.draganddrop) {
// Browser supports HTML5 DnD.
// Bind the event listeners for the image elements
var images = document.querySelectorAll('#images img');
[].forEach.call(images, function (img) {
img.addEventListener('dragstart', handleDragStart, false);
img.addEventListener('dragend', handleDragEnd, false);
});
// Bind the event listeners for the canvas
var canvasContainer = document.getElementById('canvas-container');
canvasContainer.addEventListener('dragenter', handleDragEnter, false);
canvasContainer.addEventListener('dragover', handleDragOver, false);
canvasContainer.addEventListener('dragleave', handleDragLeave, false);
canvasContainer.addEventListener('drop', handleDrop, false);
} else {
// Replace with a fallback to a library solution.
alert("This browser doesn't support the HTML5 Drag and Drop API.");
}

window.onload = function () {
var canvas = new fabric.Canvas('canvas');

function handleDragStart(e) {
[].forEach.call(images, function (img) {

function handleDragLeave(e) {
this.classList.remove('over');
}
function handleDrop(e) {

e.stopPropagation(); // stops the browser from redirecting.
}
var img = document.querySelector('#images img.img_dragging');
var newImage = new fabric.Image(img, {
width: img.width,
height: img.height,
// Set the center of the new object based on the event coordinates relative

newImage.hasControls = newImage.hasBorders = false;
canvas.add(newImage);
return false;
}
function handleDragEnd(e) {
// this/e.target is the source node.
[].forEach.call(images, function (img) {
img.classList.remove('img_dragging');

Thanks
Well, the question is quite old^^
I have updateted the fiddle, no it will work in Firefox as well.
Fiddle
function handleDrop(e) {
// this / e.target is current target element.
e.preventDefault(); //I've altert this line for FireFox
As far as I understand, drag and drop is not already provided by fabricjs,
fiddling it will be quite interesting.
Well I m new to javascript and fabricJS but I think this fiddle might help

The accepted answer no longer works.
This is for drag and drop from desktop using the dataTransfer interface.
canvas.on('drop', function(event) {
// prevent the file to open in new tab
event.e.stopPropagation();
event.e.stopImmediatePropagation();
event.e.preventDefault();
// Use DataTransfer interface to access the file(s)
if(event.e.dataTransfer.files.length > 0){
var files = event.e.dataTransfer.files;
for (var i = 0, f; f = files[i]; i++) {
// Only process image files.
if (f.type.match('image.*')) {
// Read the File objects in this FileList.
var reader = new FileReader();
// listener for the onload event
reader.onload = function(evt) {
// put image on canvas
fabric.Image.fromURL(evt.target.result, function(obj) {
obj.scaleToHeight(canvas.height);

I am using GWT2.3 in my project.
I want to increase editableTextBox width when user click on editableTextCell.
Problem is My Column width is 200 Px. when user clicks on editableTextCell then that TextBox width is around 125px in EditableTextCell is less as compare to column width.
I added EditTextCell in Celltable's column
Column stringColumn = new Column(new EditTextCell()) {
// My Code
}
cellTable.addColumn(stringColumn, "MyColumn");
cellTable.setColumnWidth(checkBoxColumn, 200, Unit.PX);
I tried following way to increase TextBox width but problem is I cannot edit in textbox + focus not losses
#Override
public void onBrowserEvent(Context context, Element elem,Record object, NativeEvent event) {
String type = event.getType();
int editedTexBoxSize = (cellTable.getOffsetWidth()-100)/cellTable.getColumnCount();
if(elem.getInnerHTML().startsWith("<INPUT")){
String test = elem.getInnerHTML();
// test = <INPUT tabIndex=-1 value=P __eventBits="2048"></INPUT>
test= test.replace("value", " size="+editedTexBoxSize+" value");
// test = <INPUT tabIndex=-1 size=131 value=P __eventBits="2048"></INPUT>
elem.setInnerHTML(test);
}
super.onBrowserEvent(context, elem, object, event);
}
I want to Increase(set) TextBox width appear in EditTextCell is equal to column Width.
Any Solution ?
In my project I do that:
cellTable.getColumn(cellTable.getColumnIndex(column)).setCellStyleNames(CELL_CSS);
.edit-cell input {
width: 290px;
}
Finally the answer !
I tried this even simplier using UIBinder by adding :
.edit-cell input {
width: 30px;
text-align: right;
}
Then for the cell table I added
<c:CellTable
addStyleNames='{style.edit-cell}'
ui:field='itemTable' />
Wonderful !
You'll need to create a custom component. The out of the box EditTextCell does not allow you to set the size attribute of the input field, just the column width.
Have a look at the ValidateableInputCell impl here: In search of a GWT validation example... where art thou? for an example of how to craft a custom cell.
Admittedly the validation does not yet work but the ability to set the size on the input field within the cell does.
