I was taking a look at ViewerJS and seems like a good fit the only problem i found was title came out with %20 instead of space. I know why, but I cannot figure out how to fix it.
so it looks like this code gets worked first. how would i fix it in here to make it display with no %20.
function getPDFFileNameFromURL(url) {
var reURI = /^(?:([^:]+:)?\/\/[^\/]+)?([^?#]*)(\?[^#]*)?(#.*)?$/;
// SCHEME HOST 1.PATH 2.QUERY 3.REF
// Pattern to get last matching NAME.pdf
var reFilename = /[^\/?#=]+\.pdf\b(?!.*\.pdf\b)/i;
var splitURI = reURI.exec(url);
var suggestedFilename = reFilename.exec(splitURI[1]) ||
reFilename.exec(splitURI[2]) ||
reFilename.exec(splitURI[3]);
if (suggestedFilename) {
suggestedFilename = suggestedFilename[0];
if (suggestedFilename.indexOf('%') !== -1) {
// URL-encoded %2Fpath%2Fto%2Ffile.pdf should be file.pdf
try {
suggestedFilename =
reFilename.exec(decodeURIComponent(suggestedFilename))[0];
} catch(e) { // Possible (extremely rare) errors:
// URIError "Malformed URI", e.g. for "%AA.pdf"
// TypeError "null has no properties", e.g. for "%2F.pdf"
}
}
}
return suggestedFilename || 'document.pdf';
}
var x = 'Some%20string%20with%20spaces';
x = x.replace(/%20/g, ' ');
console.log(x);

So I'm needing to get the list of file names from a range of Google Drive URLs in a spreadsheet. Browsing around the net, I came across the code below. It works but only for the old style urls, which I heard Google changed in September 2021.
Note that links are not fully functional, please replace with real links to check!
The old style is:
https://drive.google.com/file/d/1GMUwYxZxsNpLiaYOiVMBwl41LpreQ-fc/view?usp=sharing
This works correctly from the code below.
What I'd like though is two things.
It should handle a range of a couple of columns, currently reading AE2:AE, and printing out on AM2:AM. What I'd like is to go through the range: AE2:AL and print out: AM2:AT
Secondly it should also handle the newer form urls:
https://drive.google.com/file/d/0B9EZQqsLDEqDUGlsdy1oVEtETGs/view?usp=sharing&resourcekey=0-h7HOcxayPaHJ5r6dAAslVQ
Current Code:
function getNames() {
var activeRange = SpreadsheetApp.getActiveSheet().getDataRange();
var height = activeRange.getHeight();
var links = SpreadsheetApp.getActiveSheet()
.getRange("AE2:AE" + height)
.getValues();
var nameValues = [];
links.forEach((row) => {
try {
var link = row[0];
var fileID = getIdFromLink(link);
var name = DriveApp.getFileById(fileID).getName();
nameValues.push([name]);
} catch (e) {
nameValues.push(["NO NAME FOUND"]);
}
});
var nameRange = SpreadsheetApp.getActiveSheet().getRange("AM2:AM" + height);
nameRange.setValues(nameValues);
}
function getIdFromLink(link) {
var regex = new RegExp(
/(?<=https:\/\/drive\.google\.com\/file\/d\/)(.+)(?=\/)/
);
return regex.exec(link)[0];
}
How should the code above be modified to enable what I'm wanting. Sorry, I tried a couple of if/else statements, but my Javascript knowledge is severely limited.
Any help would be greatly appreciated.
Current "screenshot" showing:
(1) - Old style url - correctly picking up file name (2)
(3) - New style url - not picking up file name (4)
Your getIdFromLink() function should work just fine as long as the files have not been shared in such a way that they require a resource key as well.
To work with resource keys, use DriveApp.getFileByIdAndResourceKey(), like this:
function getFileNamesByLink() {
const sheet = SpreadsheetApp.getActiveSheet();
const sourceRange = sheet.getRange('AE2:AL');
const targetRange = sheet.getRange('AM2');
const fileNames = sourceRange.getValues()
.map(row => row.map(link => getFileNameFromLink_(link)));
targetRange
.offset(0, 0, fileNames.length, fileNames[0].length)
.setValues(fileNames);
}
function getFileNameFromLink_(link) {
if (!link) {
return null;
}
const fileId = getIdFromLink_(link);
if (!fileId) {
return NaN;
}
let file;
try {
file = DriveApp.getFileById(fileId);
} catch (error) {
try {
file = DriveApp.getFileByIdAndResourceKey(fileId, getResourceKeyFromLink_(link));
} catch (error) {
return NaN;
}
}
return file.getName();
}
function getIdFromLink_(link) {
const match = String(link).match(/file\/d\/([-\w]+)/i);
return match ? match[1] : null;
}
function getResourceKeyFromLink_(link) {
const match = String(link).match(/resourcekey=([-\w]+)/i);
return match ? match[1] : null;
}
Note that the script may time out if you have thousands of links. If that happens, process the links in a piecemeal fashion, or see if the Advanced Drive Service works for you.
Trying to check if some variables contain things, because they throw errors and break the ajax function when they don't. Problem is that just checking if data[2][0] contains something causes the following error:
Uncaught TypeError: Cannot read property '0' of undefined
I'd very much prefer not to check this in a previous stage. How do I check if data[2][0] is defined, without causing the actual checking to break my js?
Code:
//ajax ^
success: function(data){
var xp = data[0][0]; //Contains a string
var yp = data[1][0]; //Contains a string
var zp = data[2][0]; //Is not set, fails here
if(xp === ''){ //Tried using null & undefined here aswell
//Do nothing
} else {
var one = data[0][0];
var oneH = data[0][1];
var oneS = data[0][2];
}
if(yp === ''){
//Do nothing
} else {
var two = data[1][0];
var twoH = data[1][1];
var twoS = data[1][2];
}
if(zp === ''){
//Do nothing
} else {
var three = data[2][0];
var threeH = data[2][1];
var threeS = data[2][2];
}
//ajax continues v
Any help will be much appreciated.
You should check if a variable is undefined using typeof, not with an equality check against '':
if (typeof myVar === 'undefined')
You can also check if a variable is an array using Array.isArray(myVar)
I would check to see if data[2] exists first, and then redefine zp if it does.
var zp = data[2];
if (zp) zp = zp[0];
I have a config.js file which I believe is JSON which is called when the application first starts:
var config={};
config.user = [
{id:'JSMITH', priceModify:'true'},
{id:'JBLOGGS', priceModify:'false'},
]
config.price = [
{id:"price01", name:"priceName01", primary:"57.25", secondary:"34.54"},
{id:"price02", name:"priceName02", primary:"98.26", secondary:"139.45"},
{id:"price03", name:"priceName03", primary:"13.87", secondary:"29.13"}
]
To pull / push data I just use the following:
// Read
var curPrice = config.price[0].primary;
// Write
config.price[0].primary = "98.24";
How do I go about exporting the config file with the new value so that it will load next time the application is opened? I can use the file system object to write the file, I just don't understand how I would export everything (and preferably keep the same format).
I originally thought about reading the whole config file into a variable, cycling through to find the required block, id, and key and replacing the value, then writing the whole thing back, but I can't seem to figure out how to replace that specific value only.
Any help would be greatly appreciated
Edit Apologies, I forgot to mention that this application is completely offline and uses local directories
Solution
I stumbled across a few solutions to different issues which, when combined, gave me the perfect solution. First we cycle the Javascript object, building an array of the detail and then converting the array to a string:
vMethod.convertToText = function(obj) {
var string = [];
var output = '';
var count= 0;
var countTotal = 0;
if (typeof(obj) == "object" && (obj.join == undefined)) {
count= 0;
countTotal = 0;
string.push("{");
for (prop in obj) {
countTotal++;
}
for (prop in obj) {
if(count==countTotal - 1) {
string.push(prop, ": ", vMethod.convertToText(obj[prop]),'}\r\n');
} else {
string.push(prop, ": ", vMethod.convertToText(obj[prop]), ",");
}
count++;
};
} else if (typeof(obj) == "object" && !(obj.join == undefined)) {
count= 0;
countTotal = 0;
string.push("[\r\n")
for (prop in obj) {
countTotal++;
}
for(prop in obj) {
if(count==countTotal - 1) {
string.push(vMethod.convertToText(obj[prop]),'];\r\n');
} else {
string.push(vMethod.convertToText(obj[prop]), ",");
}
count++;
}
} else if (typeof(obj) == "function") {
string.push(obj.toString())
} else {
string.push(JSON.stringify(obj))
}
output = string.join("").toString();
//output = output.slice(1, -1);
return output;
}
Then we clean the array (neccessary for me to remove excess characters)
vMethod.cleanConfigText = function() {
var outputText = vMethod.convertToText(config);
outputText = outputText.slice(1, -1);
outputText = 'var config = {};\r\n'+outputText;
outputText = outputText.replace('user:','config.user =');
outputText = outputText.replace(',price:','config.price =');
outputText = outputText.slice(0, -2);
outputText = outputText.replace(/"/g, "'")
return outputText;
}
Finally a function to export the object into my config.js file:
vMethod.writeToConfig = function() {
vObject.fileSystem = new ActiveXObject('Scripting.FileSystemObject');
vObject.fileSystemFile = vObject.fileSystem.CreateTextFile('source\\js\\config.js',true);
vObject.fileSystemFile.Write(vMethod.cleanConfigText());
vObject.fileSystemFile.Close();
delete vObject.fileSystemFile;
delete vObject.fileSystem;
}
So when I want to export a change in the config, I just call:
vMethod.writeToConfig();
The only difference in the file format is that the commas appear at the start of a trailing line rather than the end of a preceding line but I can live with that!
Edit Turns out I'm anally retentive and the commas were bugging me
Added these to the clean up function and now the config is identical to before but without the indent
outputText = outputText.replace(/[\n\r]/g, '_');
outputText = outputText.replace(/__,/g, ',\r\n');
outputText = outputText.replace(/__/g, '\r\n');
Thank you to those that looked at the question and tried to help, very much appreciated.
Edit
DO NOT READ THE SOLUTION ABOVE, IT IS IN THE WRONG PLACE AND THERFORE IS NOT A VALID ANSWER. YOU'VE BEEN WARNED.
You can use a very popular npm package: https://www.npmjs.com/package/jsonfile . There are many but I've choosen this one.
Usually config stuff should be in json or .env files.
Now, all you have to do is use jsonfile's API to read/write JSON and parse (the package does the serialization/deserialization) it at the beginning when the application starts.
Example:
var jsonfile = require('jsonfile');
var util = require('util');
var config = null;
var file = './config.json';
// Reading
jsonfile.readFile(file, function(err, obj) {
config = obj;
});
// Writing
// Edit your config blah blah
config.user = [
{id:'JSMITH', priceModify:'true'},
{id:'JBLOGGS', priceModify:'false'},
];
config.price = [
{id:"price01", name:"priceName01", primary:"57.25", secondary:"34.54"},
{id:"price02", name:"priceName02", primary:"98.26", secondary:"139.45"},
{id:"price03", name:"priceName03", primary:"13.87", secondary:"29.13"}
];
jsonfile.writeFile(file, config, function (err) {
if(err) return err;
console.log('Config saved to file!');
});
I have a very strange issue that I am running into. I am using jsTree from JQueryUI on one of my sites, and I have different implementations of it used in different .js files. One of them seems to work, which is very confusing as it uses almost identical code (only the variable names are different) to the implementation that is broken. The problem comes from the contextmenu function. The code I am using is as follows:
$(document).ready(function () {
if(typeof dryerList == 'undefined' || dryerList.length == 0) {
var dryerList = [];
$.ajax({
url:'../TrackingApp/getGrainBins.php?t=234.23423452353',
async: false,
success: function(text) {
try {
dryerList = $.parseJSON(text);
} catch (e) {
alert('ERROR: ' + e);
}
if(dryerList.length == 0) {
alert('ERROR: No fleet data received.')
}
}
});
}
$("#dryerListTree").jstree({
plugins : ['json_data', 'ui', 'themes', 'contextmenu'],
contextmenu: {items: customBinMenu},
json_data : { data: binNodes }
});
$('#dryerListTree').bind("dblclick.jstree", function (event) {
var node = $(event.target).closest("li");
var id = node[0].id;
for(i=0; i < dryerList.length; i++) {
if(id == dryerList[i].id) {
centerMap(dryerList[i].y, dryerList[i].x);
break;
}
}
});
});
function customBinMenu(node) {
if ($(node).hasClass("folder")) {
return;
}
var items = {
centerItem: {
label: "Locate",
action: function () {
// Centers map on selected bin
var id = node[0].id;
for(i=0; i < dryerList.length; i++) {
if(id == dryerList[i].id) {
centerMap(dryerList[i].y, dryerList[i].x);
break;
}
}
}
},
dashboardItem: {
label: "Dashboard",
action: function () {
// Opens dryer info window over map
var id = node[0].id;
var dryerIndex = -1;
for(i=0; i < dryerList.length; i++) {
if(id == dryerList[i].id) {
dryerIndex = i;
break;
}
}
}
}
};
return items;
}
The strange bit is, the double-click handler works just fine. When I get to the customBinMenu() function, the dryerList array is there, and dryerList[0] contains 4 of the 5 values that it should- but somehow the 'id' element has been dropped from that object. I have been looking at this for quite some time, and I can't figure out how it can drop a single element from the object without losing any other data, especially when identical code is working for a similar list. Any suggestions?
Ok, I read in your question: 'and dryerList[0] contains 4 of the 5 values that it should- but somehow the 'id' element has been dropped from that object'
So by 'element' and 'value' I assume you mean 'attribute': the node's 'id'-attribute to be precise ??
I see in your code: var id = node[0].id;
That should be: var id = node[0].getAttribute("id");
Good luck!
UPDATE 1:
Ok, if (as per your comment) var id = node[0].id; (getting id from node[0]) is ok, then if(id == dryerList[i].id) looks wrong, since you just (re-)defined id to be the value of node[0]'s id.
Actually I would not use 'id' as a var-name (in this case).
So what if you did: var idc = node[0].getAttribute("id");
and then: if(idc === dryerList[i].getAttribute("id"))
UPDATE 5: You still have some errors by the way:
You forgot a semi-colon to close the alert in:
if(dryerList.length == 0) {
alert('ERROR: No fleet data received.')
}
You should use '===' to compare with '0' on line 2 and 14
naturally in real life you would define function customBinMenu(node) before it was used in your document.ready function.
Fixed by swapping code order.
The same goes for this document.ready function where you used var dryerList before it was defined.
Fixed by: var dryerList = dryerList || []; if(dryerList.length === 0){//ajax & json code}
Could you please confirm if this fiddle, which is now valid javascript, represents your intended baseline-code that still results in your problem of the 'id'-attribute being 'undefined' in dryerList's node-collection (since the code you posted contained some simple errors that are fixed in this jsfiddle, excluding the things mentioned in update 1, since you commented that this is not the problem) ?
May I ask (since you start at document.ready), why do you (still) check if dryerList already exists?
May I ask if you could update that corrected fiddle with some demo-data for us to toy around with?
I'm trying to probe the clientCaps object in Javascript (I'm not very familiar with behaviours in MSIE). But not having much luck.
Due to other constraints, I can't really modify the HTML of the page and hence trying to add an element dynamically. The code I'm using is shown below - I keep getting exceptions (object doesn't support this property or method). Any ideas what I'm doing wrong?
var out="";
try {
var b = document.getElementsByTagName("body")[0];
var s = document.createElement("div");
// attempt 1 - exception
// s.id="oClientCaps";
// s.style.behaviour="url('#default#clientCaps')";
//
// attempt 2 - exception
// s.innerHTML='<a ID="oClientCaps" style="behavior:url(#default#clientcaps)"></a>';
//
// attempt 3 - exception
s.id="oClientCaps";
s.addBehavior ("#default#clientCaps");
b.appendChild(s);
var clids = Array('{7790769C-0471-11D2-AF11-00C04FA35D02}', // address bk
...
'{08B0E5C0-4FCB-11CF-AAA5-00401C608500}'); // MS VM
for(i=0;i<clids.length;i++) {
if(oClientCaps.isComponentInstalled(clids[i],"ComponentID")){
out+=clsids[i]
+ oClientCaps.getComponentVersion(clids[i],"ComponentID")
+ '; ';
} else {
out+='N; '
}
}
} catch (e) {
out+="clientCaps failed";
}
return out;
TIA
Found that the following works (although I'm not sure why the other methods failed):
var b = document.getElementsByTagName("body")[0];
var s = document.createElement("div");
s.innerHTML="<div style='behavior:url(#default#clientCaps)' ID='oClientCaps' ></div>";
b.appendChild(s);
(etc)
