I hope everyone is in good health health and condition.
Recently, I have been working on Google Docs hyperlinks using app scripts and learning along the way. I was trying to get all hyperlink and edit them and for that I found an amazing code from this post. I have read the code multiple times and now I have a good understanding of how it works.
My confusion
My confusion is the recursive process happening in this code, although I am familiar with the concept of Recursive functions but when I try to modify to code to get only the first hyperlink from the document, I could not understand it how could I achieve that without breaking the recursive function.
Here is the code that I am trying ;
/**
* Get an array of all LinkUrls in the document. The function is
* recursive, and if no element is provided, it will default to
* the active document's Body element.
*
* #param {Element} element The document element to operate on.
* .
* #returns {Array} Array of objects, vis
* {element,
* startOffset,
* endOffsetInclusive,
* url}
*/
function getAllLinks(element) {
var links = [];
element = element || DocumentApp.getActiveDocument().getBody();
if (element.getType() === DocumentApp.ElementType.TEXT) {
var textObj = element.editAsText();
var text = element.getText();
var inUrl = false;
for (var ch=0; ch < text.length; ch++) {
var url = textObj.getLinkUrl(ch);
if (url != null) {
if (!inUrl) {
// We are now!
inUrl = true;
var curUrl = {};
curUrl.element = element;
curUrl.url = String( url ); // grab a copy
curUrl.startOffset = ch;
}
else {
curUrl.endOffsetInclusive = ch;
}
}
else {
if (inUrl) {
// Not any more, we're not.
inUrl = false;
links.push(curUrl); // add to links
curUrl = {};
}
}
}
if (inUrl) {
// in case the link ends on the same char that the element does
links.push(curUrl);
}
}
else {
var numChildren = element.getNumChildren();
for (var i=0; i<numChildren; i++) {
links = links.concat(getAllLinks(element.getChild(i)));
}
}
return links;
}
I tried adding
if (links.length > 0){
return links;
}
but it does not stop the function as it is recursive and it return back to its previous calls and continue running.
Here is the test document along with its script that I am working on.
https://docs.google.com/document/d/1eRvnR2NCdsO94C5nqly4nRXCttNziGhwgR99jElcJ_I/edit?usp=sharing
I hope you will understand what I am trying to convey, Thanks for giving a look at my post. Stay happy :D
I believe your goal as follows.
You want to retrieve the 1st link and the text of link from the shared Document using Google Apps Script.
You want to stop the recursive loop when the 1st element is retrieved.
Modification points:
I tried adding
if (links.length > 0){
return links;
}
but it does not stop the function as it is recursive and it return back to its previous calls and continue running.
About this, unfortunately, I couldn't understand where you put the script in your script. In this case, I think that it is required to stop the loop when links has the value. And also, it is required to also retrieve the text. So, how about modifying as follows? I modified 3 parts in your script.
Modified script:
function getAllLinks(element) {
var links = [];
element = element || DocumentApp.getActiveDocument().getBody();
if (element.getType() === DocumentApp.ElementType.TEXT) {
var textObj = element.editAsText();
var text = element.getText();
var inUrl = false;
for (var ch=0; ch < text.length; ch++) {
if (links.length > 0) break; // <--- Added
var url = textObj.getLinkUrl(ch);
if (url != null) {
if (!inUrl) {
// We are now!
inUrl = true;
var curUrl = {};
curUrl.element = element;
curUrl.url = String( url ); // grab a copy
curUrl.startOffset = ch;
}
else {
curUrl.endOffsetInclusive = ch;
}
}
else {
if (inUrl) {
// Not any more, we're not.
inUrl = false;
curUrl.text = text.slice(curUrl.startOffset, curUrl.endOffsetInclusive + 1); // <--- Added
links.push(curUrl); // add to links
curUrl = {};
}
}
}
if (inUrl) {
// in case the link ends on the same char that the element does
links.push(curUrl);
}
}
else {
var numChildren = element.getNumChildren();
for (var i=0; i<numChildren; i++) {
if (links.length > 0) { // <--- Added or if (links.length > 0) break;
return links;
}
links = links.concat(getAllLinks(element.getChild(i)));
}
}
return links;
}
In this case, I think that if (links.length > 0) {return links;} can be modified to if (links.length > 0) break;.
Note:
By the way, when Google Docs API is used, both the links and the text can be also retrieved by a simple script as follows. When you use this, please enable Google Docs API at Advanced Google services.
function myFunction() {
const doc = DocumentApp.getActiveDocument();
const res = Docs.Documents.get(doc.getId()).body.content.reduce((ar, {paragraph}) => {
if (paragraph && paragraph.elements) {
paragraph.elements.forEach(({textRun}) => {
if (textRun && textRun.textStyle && textRun.textStyle.link) {
ar.push({text: textRun.content, url: textRun.textStyle.link.url});
}
});
}
return ar;
}, []);
console.log(res) // You can retrieve 1st link and test by console.log(res[0]).
}
Hi all) I need to get all links from google document. I found that general approach:
function getAllLinks(element) {
var links = [];
element = element || DocumentApp.getActiveDocument().getBody();
if (element.getType() === DocumentApp.ElementType.TEXT) {
var textObj = element.editAsText();
var text = element.getText();
Logger.log("text " + text);
var inUrl = false;
for (var ch=0; ch < text.length; ch++) {
var url = textObj.getLinkUrl(ch);
if (url != null) {
if (!inUrl) {
// We are now!
inUrl = true;
var curUrl = {};
curUrl.element = element;
curUrl.url = String( url ); // grab a copy
curUrl.startOffset = ch;
}
else {
curUrl.endOffsetInclusive = ch;
}
}
else {
if (inUrl) {
// Not any more, we're not.
inUrl = false;
links.push(curUrl); // add to links
curUrl = {};
}
}
}
}
else {
var numChildren = element.getNumChildren();
for (var i=0; i<numChildren; i++) {
links = links.concat(getAllLinks(element.getChild(i)));
}
}
Logger.log(links);
}
It works perfectly fine if i, for example, type url in text, but if add link via menu ("Insert" -> "Link") it doesn't work, function getLinkUrl() returns null. Documentation contains info about Link class, i thought all links represented by it, but don't understand why i can't get link inserted via menu.
I thought maybe i can use some regular expression on text of document element, but if i add link via menu item i can specify custom label for link, which may not contain url in it.
Have anyone faced this scenario? What i missed?
After Chrome 58 update few features like Bold, Italic & Underline stopped working. On debugging i found that execCommand('strikethrough') is not striking the selected text.
formatMultiple: function(tag)
{
this.inline.formatConvert(tag);
this.selection.save();
document.execCommand('strikethrough'); //HERE, IT IS NOT STRIKING THE TEXT
this.$editor.find('strike').each($.proxy(function(i,s)
{
var $el = $(s);
this.inline.formatRemoveSameChildren($el, tag);
var $span;
if (this.inline.type)
{
$span = $('<span>').attr('data-redactor-tag', tag).attr('data-verified', 'redactor');
$span = this.inline.setFormat($span);
}
else
{
$span = $('<' + tag + '>').attr('data-redactor-tag', tag).attr('data-verified', 'redactor');
}
$el.replaceWith($span.html($el.contents()));
if (tag == 'span')
{
var $parent = $span.parent();
if ($parent && $parent[0].tagName == 'SPAN' && this.inline.type == 'style')
{
var arr = this.inline.value.split(';');
for (var z = 0; z < arr.length; z++)
{
if (arr[z] === '') return;
var style = arr[z].split(':');
$parent.css(style[0], '');
if (this.utils.removeEmptyAttr($parent, 'style'))
{
$parent.replaceWith($parent.contents());
}
}
}
}
}, this));
// clear text decoration
if (tag != 'span')
{
this.$editor.find(this.opts.inlineTags.join(', ')).each($.proxy(function(i,s)
{
var $el = $(s);
var property = $el.css('text-decoration');
if (property == 'line-through')
{
$el.css('text-decoration', '');
this.utils.removeEmptyAttr($el, 'style');
}
}, this));
}
if (tag != 'del')
{
var _this = this;
this.$editor.find('inline').each(function(i,s)
{
_this.utils.replaceToTag(s, 'del');
});
}
this.selection.restore();
this.code.sync();
},
I tested creating a fiddle with document.execCommand('strikethrough') and it worked. Even in browser`s console it works. Wondering what could have changed?
Same issue were already reported here: Redactor editor text format issues with Chrome version 58 and work around solution has been provided there. Please have a look.
could someone please help me to find out why this won't work on safari browser? It seems to work really well in all other browsers apart from Safari. I really could not work it out.
Any help will be most appreciated.

I am using zoho for live chat in my website. How to get that pop up which usually comes in most of the website
its code is some thing like this...
<div style="height:300px; width:300px; padding-top:20px;"><iframe style='overflow:hidden;width:100%;height:100%;' frameborder='0' border='0' src='http://chat.zoho.com/mychat.sas?U=c36599f3bbee3974d1af8b95ee04001b&chaturl=helpdesk&V=********************Center&smiley=false'></iframe></div>
How to make sure that this iframe must be loaded in a pop up..
try using window.open
window.open("http://chat.zoho.com/mychat.sas?U=c36599f3bbee3974d1af8b95ee04001b&chaturl=helpdesk&V=********************Center&smiley=false","mywindow","location=1,status=1,scrollbars=1,width=100,height=150");
Add page onLoad event to popup.
<body onLoad="window.open('http://chat.zoho.com/mychat.sas?U=c36599f3bbee3974d1af8b95ee04001b&chaturl=helpdesk&V=********************Center&smiley=false','mywindow','location=1,status=1,scrollbars=1,width=100,height=150');">
