Why does setting objectPosition cause my JavaScript to crash? - javascript

Style objectPosition Property gives this example of setting objectPosition:
document.getElementById("myImg").style.objectPosition = "0 10%";
However, when I try to set objectPosition it causes my JavaScript to crash.
In the following code I use CSS to set objectPosition like this:
#img1 {
object-position: 0 0;
width: 635px ;
height: 580px ;
}
Near the bottom of function getImg, my debug code (the “insert” statement) shows it set to “0px 0px”. However, if I proceed this with
imgStyle.objectPosition = "0 0";
The “insert” statement and all following statements are not executed. Here’s my full code with the offending statement commented out:
"use strict";
const numberOfFigures = document.getElementsByTagName('figure').length;
const scale = 3; // scaling up factor
// The function "insert" is used purely for debug purposes
function insert(figNum) {
document.getElementById("para").innerHTML = "OK so far" + figNum;
}
// Create all thumbnails & big images.
for (let i = 0; i < numberOfFigures; i++) {
getImg(i + 1);
}
function getImg(figNum) {
// Create the thumbnails and big images
let startPosn = "0px"; // x-coordinate of object-position for thumbnail
var btnDiv = document.createElement('div');
btnDiv.setAttribute("id", "bigImg" + figNum);
btnDiv.style.backgroundColor = "white";
// Get the figure caption
const figcap = document.getElementById("fig" + figNum).firstElementChild;
btnDiv.innerHTML =
'<button type="button"' +
'class="displayBtn"' +
'onclick="hideBigImg (' +
figNum +
')">Hide large image</button>';
const btnPtr = figcap.appendChild(btnDiv);
/* Append the button to the

var imgDiv = document.createElement('div');
imgDiv.setAttribute("id", "imgDiv" + figNum);
if (figNum === 1) {
/* First image needs height: 100vh or only the top slice is

them. */

The reason why the program 'crashes' or more specifically throws an Exception is because you are trying to modify the properties of a read-only object.
In detail:
const img = document.querySelector("img");
const imgStyle = getComputedStyle(img); // imgStyle is a read-only object
imgStyle.objectPosition = "0 0";
The above code will throw:
Uncaught DOMException: Failed to set the 'object-position' property on 'CSSStyleDeclaration': These styles are computed, and therefore the 'object-position' property is read-only.
As stated in the MDN documentation:
"The object from getComputedStyle is read-only, and should be used to inspect the element's style — including those set by a element or an external stylesheet.
The element.style object should be used to set styles on that element, or inspect styles directly added to it from JavaScript manipulation or the global style attribute."
So, based on the docs, you should use the element.style object for setting the properties:
img.style.objectPosition = "0 0";

How to add a line break in oldschool javascript div

I have to alter the following code somehow to add line breaks to the labels on the buttons generated by AddRemoteButtonText. Tried everything I found on this site, but nothing worked yet (most probably because I`m just starting out coding javascript). Mostly tried adding another variable to the function and then implementing it by "\n" .
var size = 20;
var repeat_timer;
function AddRemoteButtonText(num, posx, posy, wx, wy, color, label, remote, command, initial_delay, repeat_delay)
{
document.write('<div id="' + num + '" class="button ' + color + '" style="position:absolute; top:' + posy + 'px; left:' + posx + 'px; height:' + wy + 'px; width:' + wx + 'px; line-height: ' + wy + 'px;" align="center">' + label + '</div>');
document.getElementById(num).onmouseup = function () { SendIRCommand (num,remote,command,initial_delay,repeat_delay); EndSendCommand (num) };
document.getElementById(num).onmouseleave = function () { EndSendCommand (num) };
}
}
};
Thanks for your answer!
Add '<br>' like in the below example
document.write(variable +'<br/>'+ variable2);
I would probably do it like this (simplified for example purposes):
var i = 0;
var aboveLineBreak;
var belowLineBreak;
function AddRemoteButtonText() {
console.log(i);
//define some text to print to the button
aboveLineBreak = "above br" + i;
belowLineBreak = "below br" + i;
//create a button object
var btn = document.createElement("DIV");
//add our text, including the line break, to the button
btn.appendChild(document.createTextNode(aboveLineBreak));
btn.appendChild(document.createElement("BR"));
btn.appendChild(document.createTextNode(belowLineBreak));
//define our button's CSS style
btn.setAttribute("class", "button red");
//to set the position, do:
//btn.style.position = "absolute";
//btn.style.top = whatever;
//and so on...
//add listeners if needed...
btn.onmouseup = function () { console.log("foo"); };
//finally add the button to the document's body and increment i
document.body.appendChild(btn);
i++;
}
.button {
width: 33%;
height: 45px;
}
.red {
background-color: darkred;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<button onClick="AddRemoteButtonText();"> Add Remote Button Text </button>
</body>
</html>
Not the most beautiful buttons, but if you simply substitute my CSS with your own you should have a working line break. If not, we will need you to post your CSS so we can have a look at it.

How to wrap divs inside a new div?

I'm trying to wrap the two divs <div class="cm-cp-title"> and <div class="cm-cp-value"> inside a div called cm-cp-container. Actually it is working, but it merges all together, it is shown like below after I put the wrapAll();
what is that issues? im wonder how to separate each of it?
Below is the result i needed,
$(function() {
// document
'use strict';
var coupon = $('div.cm-coupon');
// Settings
coupon.each(function() {
var _coupon = $(this);
var cpValue = _coupon.attr("data-value") + "";
// Different Data type
if (_coupon.data('type') == "c1")
{
_coupon.addClass('red').css(
{
"background" : "black",
"display": "table"}
);
_coupon.append(
'<div class="cm-cp-title">' + 'black here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>'
);
}
else if (_coupon.data('type') == "c2")
{
_coupon.addClass('green').css(
{
"background" : "green",
"display": "table"}
);
_coupon.append('<div class="cm-cp-title">'+ 'green here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
}
else if (_coupon.data('type') == "c3")
{
_coupon.addClass('blue').css(
{
"background" :"blue",
"display": "table"}
);
_coupon.append('<div class="cm-cp-title">'+ 'blue here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
} else {
return false;
}
});
$('.cm-cp-title, .cm-cp-value').wrapAll("<div class='cm-cp-container'/>");
// alignment to middle
$('.cm-coupon').on('resize',function() {
$(".cm-cp-container").css('margin-top', function() {
return($('.cm-coupon').height() - $(this).height()) / 2
});
}).resize();
});//end
.cm-coupon {
width: 340px;
height: 156px;
float: left;color: #fff;
margin: 0 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cm-coupon" data-type="c1" data-value="50"></div>
<div class="cm-coupon" data-type="c2" data-value="20"></div>
<div class="cm-coupon" data-type="c3" data-value="70"></div>
Working Snippet :
$(function() {
'use strict';
var coupon = $('div.cm-coupon');
var colors = new Map([["c1", "black"], ["c2", "green"], ["c3", "blue"]]);
// Settings
coupon.each(function() {
var _coupon = $(this);
var cpValue = _coupon.attr("data-value") + "";
var color = colors.get(_coupon.data('type'));
_coupon.addClass(color).css({
"background" : color,
"display": "table"
});
_coupon.append('<div class="cm-cp-title">' + color + ' here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
$(_coupon.children()).wrapAll("<div class='cm-cp-container'/>");
});
// alignment to middle
$('.cm-coupon').on('resize',function() {
$(".cm-cp-container").css('margin-top', function() {
return($('.cm-coupon').height() - $(this).height()) / 2
});
}).resize();
});//end
.cm-coupon {
width: 340px;
height: 156px;
float: left;
color: #fff;
margin: 0 10px;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cm-coupon" data-type="c1" data-value="50"></div>
<div class="cm-coupon" data-type="c2" data-value="20"></div>
<div class="cm-coupon" data-type="c3" data-value="70"></div>
Explanation :
First
I reduced the code removing the if statements because the only difference between the blocks if/else/else was the color ("black"/"green"/"blue"). I used a Map instead, to switch the value of the color according to the type.
What I did:
var colors = new Map([["c1", "black"], ["c2", "green"], ["c3", "blue"]]);
coupon.each(function () {
var _coupon = $(this);
var color = colors.get(_coupon.data('type'));
And then use color where need to.
Second
The problem you are encoutering is because you are not wrapping all the divs into the container, but wrapping the children of the divs.
So
$('.cm-cp-title, .cm-cp-value').wrapAll("<div class='cm-cp-container'/>");
becomes
$(coupon).wrapAll("<div class='cm-cp-container'/>");
EDIT :
It seems like you want to wrap the inner elements of the coupons instead.
Then use _coupon.children() instead, like this
$(_coupon.children()).wrapAll("<div class='cm-cp-container'/>");
and move it inside the each loop.
I edited the snippet. you can check.
In fact, the way you did it in your code, it is selecting all the matching elements in the document and wrapping it altogether. That is why the last two were moving inside the black div.

Horizontal pagination in android webview like ios

func setupScrollDirection() {
switch readerConfig.scrollDirection {
case .vertical, .defaultVertical, .horizontalWithVerticalContent:
scrollView.isPagingEnabled = false
paginationMode = .unpaginated
scrollView.bounces = true
break
case .horizontal:
scrollView.isPagingEnabled = true
paginationMode = .leftToRight
paginationBreakingMode = .page
scrollView.bounces = false
break
}
}
Is any alternate to the above code, Iam trying to use webview horizontally.I have tried with javaScript like this
String varMySheet = "var mySheet = document.styleSheets[0];";
String addCSSRule = "function addCSSRule(selector, newRule) {"
+ "ruleIndex = mySheet.cssRules.length;"
+ "mySheet.insertRule(selector + '{' + newRule + ';}', ruleIndex);"
+ "}";
/* String insertRule1 = "addCSSRule('html', 'padding: 0px; height: "
+ (webView.getMeasuredHeight() / getResources().getDisplayMetrics().density)
+ "px; -webkit-column-gap: 0px; -webkit-column-width: "
+ webView.getMeasuredWidth() + "px;')";*/
float height=webView.getMeasuredHeight() / getResources().getDisplayMetrics().density;
String insertRule1 = "addCSSRule('html', 'margin:0px; padding:0px; height: "
+ (height)
+ "px; -webkit-column-gap: 0px; -webkit-column-width: "
+ webView.getMeasuredWidth() + "px;')";
webView.loadUrl("javascript:" + varMySheet);
webView.loadUrl("javascript:" + addCSSRule);
webView.loadUrl("javascript:" + insertRule1);
But the webview has a empty space below and scrolling is also not paginated.
adding style="overflow-x: auto; overflow-y: -webkit-paged-x;" to your body can be done with javascript:
String js = "javascript:function initialize() { " +
"var d = document.getElementsByTagName('body')[0];" +
"d.style.overflow = '-webkit-paged-x';" +
"}";
webView.loadUrl(js);
webView.loadUrl("javascript:initialize()");
along with overriding onOverScrolled in your webview like that:
#Override
protected void onOverScrolled(int scrollX, int scrollY, boolean clampedX, boolean clampedY) {
scrollY = 0; // disables vertical scroll
super.onOverScrolled(scrollX, scrollY, clampedX, clampedY);
}
will result in horizontal scrolling without the pagination.
don't have solution for the pagination yet.

Adding CSS rule using JS

I wish to add a new CSS rule on pageload and modify it on window resize using Javascript (or jQuery). I've tried the following, but it doesn't seem to be working:
var w = $(window).width();
var itemWidth = ((w/154)+4).toFixed();
var itemWidthLeft = itemWidth/2;
var itemWidthRight = itemWidth/2;
document.styleSheets[0].insertRule('figure.itemMargin { margin-left: '+itemWidthLeft+'; margin-right: '+itemWidthRight+'; }',0);
What am I doing wrong?
you are missing px.
document.styleSheets[0].insertRule('figure.itemMargin { margin-left: '+itemWidthLeft+'px; margin-right: '+itemWidthRight+'px; }',0);
you aren't including the variables in the string, try this
document.styleSheets[0].insertRule('figure.itemMargin { margin-left: ' + itemWidthLeft + '; margin-right: ' + itemWidthRight + '; }',0);
Create a style element in your head and append the rules to it.
For example
<style type="text/css" id="cssChanges"></style>
and just use
$("#cssChanges").append('figure.itemMargin { margin-left: ' + itemWidthLeft + 'px; margin-right: ' + itemWidthRight + 'px; }');

Drag/drop & delete dynamic text on HTML canvas

I've found a number of tutorials online for dragging and dropping images and shapes within an HTML canvas. But they all seem to be aimed at moving objects that are generated within the canvas when the page loads. I'm building an app that lets the user click a button on a virtual keyboard, then click on the canvas to have the corresponding number or character appear. This is my code:
<script type="text/javascript">
var mathCanvas = document.getElementById("matharea");
var ctx = mathCanvas.getContext("2d");
ctx.font="20px Arial";
var placementCallback = function(){}
mathCanvas.onselectstart = function(){return false;}
function insertOne(){placementCallback = function(x, y){ctx.fillText('1', x-6,y+6);}};
function insertTwo(){placementCallback = function(x, y){ctx.fillText('2', x-6,y+6);}};
function insertThree(){placementCallback = function(x, y){ctx.fillText('3', x-6,y+6);}};
mathCanvas.onclick = function(event){
placementCallback(event.offsetX, event.offsetY);
}
</script>
I cut out some of the insert functions to keep this shorter (the buttons in my HTML have an onclick attribute that calls these functions). I need to be able to select the characters that are placed on the screen and implement drag/drop and delete functionality, but I can't think of a way to do this for text that gets placed on the screen after the page loads (I'm fairly new to Javascript). How would I do this? I'm not expecting anyone to give me the code to do this, but if I could get a push in the right direction, that'd be great.
The problem is that canvas is immediate-mode. Whatever you tell it to put on the canvas it will put on the canvas, instantly. It will not give you the ability to modify that value in any way, shape or form.
Think of it like the difference between MS Paint (or your OS' equivalent) and Photoshop.
In PS, you can have layers which can be moved around and edited, and when you decide your image is done, you save it and it flattens all of that data.
When you make an image in MS Paint, as soon as you click or type, that thing that you put there is there, and it's not moving/being edited unless you erase it, draw over it, or draw a rectangle around a section and move that whole rectangle (including the pixels around what you're trying to edit).
Just calling fillText will paint the words on, that instant, but will not remember what it drew, where it is, what it is, how the text is different from the surrounding pixels, et cetera.
So your generalized solution is that you need to turn your text into objects, and then draw an aspect (the text-content) of those objects to the screen.
If your text changes, you can make a change in the object, and redraw it (because your object will have its X and Y coordinates stored, and will have its width value stored, using the context.measureText(textObj.text).width method/property), and when you click on the canvas, you can check the coordinates of the click, and if those coordinates intersect with your text-object's stored coordinates, then you can modify its position on the screen.
In that regard, you should look into those examples which deal with dragging objects on the canvas.
The button click should be treated as a way to CREATE one of those objects.
I know this is a lot of code ... But I didn't want to go through it .. It's PART of something I built a long time ago ... Just copy and paste into a html file ... I hope it helps with what you need:
