Requirement: I have a requirement to use Handsontable on my web application, where the user can enter value with two consecutive double-quotes
jsfiddle link:
sample strings:
${v=""}
var s=""
http://jsfiddle.net/a3uj6/1/
Handsontable Issue:
If the cell has Two consecutive double quotes, one double quote is missing upon copy-paste the cell to another cell.
Same issue occurs, if the user drags the cell-value to place it in the next column/cell.
NOTE: User is not doing copy/paste or dragging a multi-line text, it is just a single-line text with two consecutive quotes.
I have posted this as an issue in the github as well. Meanwhile, if there is any work-around to fix the copy/paste issue, is more welcomed.
Thanks.
this is a not elegant solution but is a workaround that works for me.
Using the hook onBeforePaste you could handle the contents pasted as follows:
onBeforePaste: (values, range) => {
const { startRow, startCol } = [range];
var content = [];
values.forEach((row, i) => {
row.forEach((value, x) => {
content.push([startRow + i, startCol + x, value]);
});
});
hotInstante.setDataAtCell(content);
return false;
},
There are the documentation of hooks used

I'm using CKEditor and I want to indent just the first line of the paragraph. What I've done before is click "Source" and edit the <p> style to include text-indent:12.7mm;, but when I click "Source" again to go back to the normal editor, my changes are gone and I have no idea why.
My preference would be to create a custom toolbar button, but I'm not sure how to do so or where to edit so that clicking a custom button would edit the <p> with the style attribute I want it to have.
Depending on which version of CKE you use, your changes most likely disappear because ether the style attribute or the text-indent style is not allowed in the content. This is due to the Allowed Content Filter feature of CKEditor, read more here: http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter
Like Ervald said in the comments, you can also use CSS to do this without adding the code manually - however, your targeting options are limited. Either you have to target all paragraphs or add an id or class property to your paragraph(s) and target that. Or if you use a selector like :first-child you are restricted to always having the first element indented only (which might be what you want, I don't know :D).
To use CSS like that, you have to add the relevant code to contents.css, which is the CSS file used in the Editor contents and also you have to include it wherever you output the Editor contents.
In my opinion the best solution would indeed be making a plugin that places an icon on the toolbar and that button, when clicked, would add or remove a class like "indentMePlease" to the currently active paragraph. Developing said plugin is quite simple and well documented, see the excellent example at http://docs.ckeditor.com/#!/guide/plugin_sdk_sample_1 - if you need more info or have questions about that, ask in the comments :)
If you do do that, you again need to add the "indentMePlease" style implementation in contents.css and the output page.
I've got a way to indent the first line without using style, because I'm using iReport to generate automatic reports. Jasper does not understand styles. So I assign by jQuery an onkeydown method to the main iframe of CKEditor 4.6 and I check the TAB and Shift key to do and undo the first line indentation.
// TAB
$(document).ready(function(){
startTab();
});
function startTab() {
setTimeout(function(){
var $iframe_document;
var $iframe;
$iframe_document = $('.cke_wysiwyg_frame').contents();
$iframe = $iframe_document.find('body');
$iframe.keydown(function(e){
event_onkeydown(e);
});
},300);
}
function event_onkeydown(event){
if(event.keyCode===9) { // key tab
event.preventDefault();
setTimeout(function(){
var editor = CKEDITOR.instances['editor1'], //get your CKEDITOR instance here
range = editor.getSelection().getRanges()[0],
startNode = range.startContainer,
element = startNode.$,
parent;
if(element.parentNode.tagName != 'BODY') // If you take an inner element of the paragraph, get the parentNode (P)
parent = element.parentNode;
else // If it takes BODY as parentNode, it updates the inner element
parent = element;
if(event.shiftKey) { // reverse tab
var res = parent.innerHTML.toString().split(' ');
var aux = [];
var count_space = 0;
for(var i=0;i<res.length;i++) {
// console.log(res[i]);
if(res[i] == "")
count_space++;
if(count_space > 8 || res[i] != "") {
if(!count_space > 8)
count_space = 9;
aux.push(res[i]);
}
}
parent.innerHTML = aux.join(' ');
}
else { // tab
var spaces = " ";
parent.innerHTML = spaces + parent.innerHTML;
}
},200);
}
}
UPDATE: Per the recommendation below, here's specifically what I'd like to do: If I double-click the mouse cursor anywhere from the "b" to the "n" of "blue-green", I want all of the word "blue-green" should be highlighted. How can this be done? Currently, depending on where you click, it treats "blue-green" as three separate character strings. So, if you double click between the "b" and "e" of "blue" it highlights only "blue" and not "-green." If you double-click the hyphen, it highlights the hyphen alone. And if you double-click between the "g" and "n" of "green" it highlights only "green" and not "blue-".
ORIGINAL: When I double-click a hyphenated word or set of characters (e.g. "123-abc" or "blue-green" etc.), only the part of the word that I double-clicked is highlighted. I'd like the whole word to be highlighted.
I'm using Windows 7 Pro. If it needs to be done on a per-application basis, I'm most interested in fixing it for Google Chrome, but any Windows-compatible web browser would be OK.
Old question, but I happen to have been working on the same issue. Here's my solution:
jsFiddle.net
"use strict"
// Tweak to make a double-click select words with hyphens
//
// As of 2016-0816, None of the major Mac browser selects whole words
// with hyphens, like "ad-lib". This tweak fixes the hypen issue.
//
// Note: Firefox 48.0 doesn't automatically select whole words with
// apostrophes like "doesn't". This tweak also treats that.
;(function selectWholeWordsWithHyphens(){
var pOutput = document.getElementById("output")
var selection = window.getSelection()
// Regex designed to find a word+hyphen before the selected word.
// Example: ad-|lib|
// It finds the last chunk with no non-word characters (except for
// ' and -) before the first selected character.
var startRegex = /(\w+'?-?)+-$/g
// Regex designed to find a hyphen+word after the selected word.
// Example: |ad|-lib
var endRegex = /^-('?-?\w+)+/
// Edge case: check if the selection contains no word
// characters. If so, then don't do anything to extend it.
var edgeRegex = /\w/
document.body.ondblclick = selectHyphenatedWords
function selectHyphenatedWords(event) {
if (!selection.rangeCount) {
return
}
var range = selection.getRangeAt(0)
var container = range.startContainer
var string = container.textContent
var selectionUpdated = false
if (string.substring(range.startOffset, range.endOffset)
.search(edgeRegex) < 0) {
// There are no word characters selected
return
}
extendSelectionBackBeforeHypen(string, range.startOffset)
extendSelectionForwardAfterHyphen(string, range.endOffset)
if (selectionUpdated) {
selection.removeAllRanges()
selection.addRange(range)
}
function extendSelectionBackBeforeHypen(string, offset) {
var lastIndex = 0
var result
, index
string = string.substring(0, offset)
while (result = startRegex.exec(string)) {
index = result.index
lastIndex = startRegex.lastIndex
}
if (lastIndex === offset) {
range.setStart(container, index)
selectionUpdated = true
}
}
function extendSelectionForwardAfterHyphen(string, offset) {
if (!offset) {
return
}
string = string.substring(offset)
var result = endRegex.exec(string)
if (result) {
range.setEnd(container, offset + result[0].length)
selectionUpdated = true
}
}
}
})()
It's a standard through all programs that it will do that because they all run off the operating system's typing configuration/program thing. To fix it you would need to do something in System32. I don't know what you would need to do but I suspect this is your problem. You should probably go into more detail though about specifically what it is you want.
I wish to capitalize the first letter of a sentence, on-the-fly, as the user types the text in a CKEditor content instance.
The strategy consists in catching each keystroke and try to replace it when necessary, that is for instance, when the inserted character follows a dot and a space. I'm fine with catching the event, but can't find a way to parse characters surrounding the caret position:
var instance = CKEDITOR.instances.htmlarea
instance.document.getBody().on('keyup', function(event) {
console.log(event);
// Would like to parse here from the event object...
event.data.preventDefault();
});
Any help would be much appreciated including a strategy alternative.
You should use keydown event (close to what you proposed):
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() === 65 /*a*/ && isFirstLetter()) {
// insert 'A' instead of 'a'
editor.insertText('A');
event.data.preventDefault();
}
});
Now - how should isFirstLetter() look like?
You have to start from editor.getSelection().getRanges() to get caret position.
You're interested only in the first range from the collection.
To extract text content from before the caret use small trick:
move start of the range to the beginning of document: range.setStartAt( editor.document.getBody(), CKEDITOR.POSITION_AFTER_START ),
use CKEDITOR.dom.walker to traverse through DOM tree in source order,
collect text nodes and find out what's before caret (is it /\. $/) - remember that you have to skip inline tags and stop on block tags - hint: return false from guard function to stop traversing.
Example of how you can use walker on range:
var range, walker, node;
range = editor.getSelection().getRanges()[0];
range.setStartAt(editor.document.getBody(), CKEDITOR.POSITION_AFTER_START);
walker = new CKEDITOR.dom.walker(range);
walker.guard = function(node) {
console.log(node);
};
while (node = walker.previous()) {}
And now few sad things.
We assumed that selection is empty when you type - that doesn't have to be true. When selection is not collapsed (empty) then you'll have to manually remove its content before calling insertText. You can use range#deleteContents to do this.
But this is not all - after deleting range's content you have to place caret in correct position - this isn't trivial. Basically you can use range#select (on the range after deleteContents), but in some cases it can place caret in incorrect place - like between paragraphs. Fixing this is... is not doable without deeeeeeeep knowledge about HTML+editables+insertions+other things :).
This solution is not complete - you have to handle paste event, deleting content (one can delete words from the start of sentence), etc, etc.
I guess there are couple of other problems I didn't even thought about :P.
So this approach isn't realistic. If you still want to implement this feature I think that you should set timer and by traversing DOM (you can use walker on range containing entire document, or recently typed text (hard to find out where it is)) find all sentences starting from lower letter and fix them.
This is what worked for me in Ckeditor 4.
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() >= 65 && event.data.getKeystroke()<=91 && encodeURI(this.getText())=="%0A" && this.getText().length==1 ) {
//uppercase the char
editor.insertText(String.fromCharCode(event.data.getKeystroke()));
event.data.preventDefault();
}
});
Is there any trick to break a label text? Because '\n' '\r' '\n\r' don't work.
Many Thanks
if you use those 2 parameters you do what you want don't you ?
app.createLabel(text).setWidth(width).setWordWrap(true)
here is an example (among other widgets ;-):
function showurl() {
var app = UiApp.createApplication();
app.setTitle("Anchor in a popup ;-)");
var panel = app.createFlowPanel()
var image = app.createImage('https://sites.google.com/site/appsscriptexperiments/home/photo.jpg').setPixelSize(50, 50)
var link = app.createAnchor('This is your link', 'https://sites.google.com/site/appsscriptexperiments/home');
var lab = app.createLabel("wrap it because it's too narrow").setWidth(90).setWordWrap(true);
var quit = app.createButton('quit');
panel.add(image).add(link).add(lab).add(quit);
app.add(panel);
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
EDIT : I found an old post(on the Google group forum, thanks again Henrique ;-) about breaking lines in toast messages and here is the code I used for that case... the principle should work for Labels too but I didn't try.
To use it, just use \n (where you want to break the line) in a variable containing your text and pass it through this function. (there are some comment in the script to explain)
function break_(msg){
var temp = escape(msg);// shows codes of all chars
msg = unescape(temp.replace(/%20/g,"%A0")); // replace spaces by non break spaces
temp = msg.replace("\n"," "); // and replace the 'newline' by a normal space
return temp; // send back the result
}
Would something like this work?
//takes a line of text and returns a flex table broken by \n
function breakLabel(text) {
var app = UiApp.getActiveApplication();
var flexTable = app.createFlexTable();
text = text.split('\n'); // split into an array
for (var i=0; i<text.length; i++){
flexTable.setWidget(i, 0, app.createLabel(text[i].toString()));
}
return flexTable;
}
Adding them to a vertical panel helps as well (not the way you want, but still..):
var vPanel = app.createVerticalPanel().setSize(100,100);
var label = app.createLabel('predominantly blabla blala blabla');
app.add(vPanel.add(label));

For anyone just now stumbling upon this, the best solution seems to be creating an HTML output for anything that needs line breaks.
Documentation
var htmlApp = HtmlService
.createHtmlOutput('<p>A change of speed, a change of style...</p>')
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.setTitle('My HtmlService Application')
.setWidth(250)
.setHeight(300);
SpreadsheetApp.getActiveSpreadsheet().show(htmlApp);
// The script resumes execution immediately after showing the dialog.
Our site is using tags like <# TAGNAME #> but CKEditor converts < and > to < and > which breaks these tags for use in our software.
I've discovered this option: config.protectedSource.push( /<#[\s\S]*##>/g ); which seems to stop the conversion if the data is saved from Source mode, but in WYSIWYG mode I can't find a way to stop the conversion. I've tried many options in their API but none of them seem to have helped, how can I fix this problem?
Were were looking at using CKEDitor to edit Smarty templates. The problem we were hitting was that it was replacing all the angle brackets and ampersands within the curly brackets, which messed everything up. This came up in a Google search so our solution should help anyone with similar issues.
CKEditor rebuilds the HTML every time you switch to Source mode and when you save, so you need to add to the HTML http://docs.cksource.com/CKEditor_3.x/Developers_Guide/Data_Processor htmlFilter.
This worked for us:
//replace Form_content with whatever your editor's id is.
htmlParser = CKEDITOR.instances.Form_content.dataProcessor.htmlFilter;
//We don't want HTML encoding on smarty tags
//so we need to change things in curly brackets
htmlParser.onText = function(text) {
//find all bits in curly brackets
var matches = text.match(/\{([^}]+)\}/g);
//go through each match and replace the encoded characters
if (matches!=null) {
for (match in matches) {
var replacedString=matches[match];
replacedString = matches[match].replace(/>/g,'>');
replacedString = replacedString.replace(/</g,'<');
replacedString = replacedString.replace(/&/g,'&');
text = text.replace(matches[match],replacedString);
}
}
return text;
}
The onText function processes all the bits that aren't in tags or comments.
I'd imagine you can do something similar by altering the code above - I've left it as is as I think our problems and required solutions are very similar.
editor.on( 'mode', function(ev) {
if ( ev.editor.mode == 'source' ) {
var str=ev.editor.getData();
str=str.replace(/&/g, "&").replace(/>/g, ">").replace(/</g, "<").replace(/"/g, "\"");
ev.editor.textarea.setValue(str);
}
});

If you type < or > in any WYSIWYG editor, they will be converted to their HTML entities in source mode.
