Take selected text, send it over to Scryfall API, then take the link and put it in the selected text

I've been able to sort out the middle bit (the API seems to be called to just fine) along with the submenu displaying. Originally I thought that just the end part wasn't working but I'm now thinking that the selection part isn't either.
What am I doing wrong with the getSelection() and what do I need to do to insert a link into said selection? (to clarify, not to replace the text with a link, but to insert a link into the text)
//Open trigger to get menu
function onOpen(e) {
DocumentApp.getUi().createAddonMenu()
.addItem('Scry', 'serumVisions')
.addToUi();
}
//Installation trigger
function onInstall(e) {
onOpen(e);
}
//I'm not sure if I need to do this but in case; declare var elements first
var elements
// Get selected text (not working)
function getSelectedText() {
const selection = DocumentApp.getActiveDocument().getSelection();
if (selection) {
var elements = selection.getRangeElements();
Logger.log(elements);
} else {
var elements = "Lack of selection"
Logger.log("Lack of selection");
}
}
//Test run
// insert here
// Search Function
function searchFunction(nameTag) {
// API call + inserted Value
let URL = "https://api.scryfall.com/cards/named?exact=" + nameTag;
// Grabbing response
let response = UrlFetchApp.fetch(URL, {muteHttpExceptions: true});
let json = response.getContentText();
// Translation
let data = JSON.parse(json);
// Jackpot
let link = data.scryfall_uri;
// Output
Logger.log(link);
}
// Test run
searchFunction("Lightning Bolt");
//Let's hope this works how I think it works
function serumVisions() {
const hostText = getSelectedText();
const linkage = searchFunction(hostText);
// Unsure what class I'm supposed to use, this doesn't
const insertLink = DocumentApp.getActiveDocument().getSelection().newRichTextValue()
.setLinkUrl(linkage);
Logger.log(linkage);
}
For the first part, I tried the getSelection() and getCursor() examples from the Google documentation but they don't seem to work, they all just keep returning null.
For the inserting link bit, I read all those classes from the Spreadsheet section of the documentation, at the time I was unaware but now knowing, I haven't been able to find a version of the same task for Google Docs. Maybe it works but I'm writing it wrong as well, idk.

Modification points:
In your script, the functions of getSelectedText() and searchFunction(nameTag) return no values. I think that this might be the reason for your current issue of they all just keep returning null..
elements of var elements = selection.getRangeElements(); is not text data.
DocumentApp.getActiveDocument().getSelection() has no method of newRichTextValue().
In the case of searchFunction("Lightning Bolt");, when the script is run, this function is always run. Please be careful about this.
When these points are reflected in your script, how about the following modification?
Modified script:
Please remove searchFunction("Lightning Bolt");. And, in this case, var elements is not used. Please be careful about this.
From your script, I guessed that in your situation, you might have wanted to run serumVisions(). And also, I thought that you might have wanted to run the individual function. So, I modified your script as follows.
function getSelectedText() {
const selection = DocumentApp.getActiveDocument().getSelection();
var text = "";
if (selection) {
text = selection.getRangeElements()[0].getElement().asText().getText().trim();
Logger.log(text);
} else {
text = "Lack of selection"
Logger.log("Lack of selection");
}
return text;
}
function searchFunction(nameTag) {
let URL = "https://api.scryfall.com/cards/named?exact=" + encodeURIComponent(nameTag);
let response = UrlFetchApp.fetch(URL, { muteHttpExceptions: true });
let json = response.getContentText();
let data = JSON.parse(json);
let link = data.scryfall_uri;
Logger.log(link);
return link;
}
// Please run this function.
function serumVisions() {
const hostText = getSelectedText();
const linkage = searchFunction(hostText);
if (linkage) {
Logger.log(linkage);
DocumentApp.getActiveDocument().getSelection().getRangeElements()[0].getElement().asText().editAsText().setLinkUrl(linkage);
}
}
When you select the text of "Lightning Bolt" in the Google Document and run the function serumVisions(), the text of Lightning Bolt is retrieved, and the URL like https://scryfall.com/card/2x2/117/lightning-bolt?utm_source=api is retrieved. And, this link is set to the selected text of "Lightning Bolt".

Getting textbox values from a CefSharp browser using javascript

I've got a winforms app that has a ChromiumWebBrowser control and some basic windows controls. I want to be able to click a button, call javascript to get the value of a textbox in the browser, and copy the returned value to a textbox in the winforms app. Here is my code:
string script = "(function() {return document.getElementById('Email');})();";
string returnValue = "";
var task = browser.EvaluateScriptAsync(script, new { });
await task.ContinueWith(t =>
{
if (!t.IsFaulted)
{
var response = t.Result;
if (response.Success && response.Result != null)
{
returnValue = (string)response.Result;
}
}
});
txtTarget.Text = returnValue;
The result that comes back however is just "{ }". I've loaded the same web page in Chrome and executed the same javascript in the dev tools and I get the textbox value as expected.
The demo I looked at had sample code, simply "return 1+1;", and when I tried that I was getting the value "2" returned instead of "{ }". Interestingly, when I tried
string script = "(function() {return 'hello';})()";
I was still getting "{ }", almost as though this doesn't work with strings.
I've been scratching my head at this for a while and haven't been able to figure out how to solve this. Am I making a very basic syntax error or is there something more complicated going on?

So I think I've figured it out:
string script = "(function() {return document.getElementById('Email').value;})();";
string returnValue = "";
var task = browser.EvaluateScriptAsync(script);
await task.ContinueWith(t =>
{
if (!t.IsFaulted)
{
var response = t.Result;
if (response.Success && response.Result != null)
{
returnValue = response.Result.ToString();
}
}
});
txtTarget.Text = returnValue;
Removing the args object from EvaluateScriptAsync seemed to fix the issue. Not sure what the problem was - perhaps it was trying to run the javascript function with an empty args object when it shouldn't take any parameters?
Either way, it's resolved now.

public void SetElementValueById(ChromiumWebBrowser myCwb, string eltId, string setValue)
{
string script = string.Format("(function() {{document.getElementById('{0}').value='{1}';}})()", eltId, setValue);
myCwb.ExecuteScriptAsync(script);
}
public string GetElementValueById(ChromiumWebBrowser myCwb, string eltId)
{
string script = string.Format("(function() {{return document.getElementById('{0}').value;}})();",
eltId);
JavascriptResponse jr = myCwb.EvaluateScriptAsync(script).Result;
return jr.Result.ToString();
}

creating a drop down list in javascript from a text file

Is this possible? If so, I could really use some help on this. I'm very new to JavaScript and thus hardly know any of the syntactical specifications, nor proper methodology.
Some functions I wrote in an external file.
var base = base || {};
base.requestAjax = function () {
try{
return new XMLHttpRequest();
} catch (e) {
try {
return new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
return new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
alert("Something is wrong with your browser! Please ensure that you have javascript functionality enabled");
return false;
}
}
}
}
base.onReadyStateChange = function(ajaxRequest, formName, formArray, method, controller) {
var methodVerified = verifyMethod(method);
if (!methodVerified) {
throw new Exception("Error: please make sure the method passed matches that of \'GET\' or \'POST\'.");
}
for (input in formArray) {
document.formName.input.value = ajaxRequest.responseText;
}
ajaxRequest.open(method, controller, true);
file.send(null);
}
base.writeDropDownList = function(file, method, path) {
var file = upload.requestAjax();
file.open(method, path, true);
if (file.readyState != 4) {
throw new Exception("Error: text file ready state not equal to 4!");
}
if (file.status != 200) {
throw new Exception("Error: text file status not equal to 200!");
}
var lines = file.responseText.split("\n");
document.writeln("<select>");
for(line in lines) {
document.writeln("<option>" + line + "</option>");
}
document.writeln("</select>");
file.send(null);
}
base.verifyMethod = function(method) {
var methodLower = method.toString().toLowerCase();
switch(methodLower) {
case "get":
case "post":
return true;
default:
return false;
}
}
The html code which attempts to implement it
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="../includes/css/adsmanager.css" />
<script type="text/javascript" src="../includes/js/base.js">
<!--
function createCountriesList() {
var file = base.requestAjax;
var path = "../includes/_notes/countries.txt";
base.writeDropDownList(file, "GET", path);
}
//-->
</script>
</head>
<body>
<form name='adsManager'>
<button type="text" value="test" onclick="createCountriesList()" />
</form>
</body>
</html>
I plan to use the functions for other things, so I figured I'd create a namespace. I found this as a reference and based most of my model off of it.
Thanks to all who can help.

What is your point of failure? Is your Javascript sending the Ajax request and receiving the response?
Is lines getting data in this line of your code?
var lines = file.responseText.split("\n");
If you are getting this far, iterate through lines and add options like this:
var select = document.getElementById('id');
select.options.add(new Option(lines[i]));
In your writeDropDownList method, I made a few changes:
added a method that will be called when your Ajax call has completed. In that method, you should check the response string and add the options to your select box
base.writeDropDownList = function(file, method, path) {
var file = upload.requestAjax();
file.open(method, path, true);
file.onreadystatechange = requestComplete;
file.send(null);
}
requestComplete()
{
if (file.readyState == 4)
{
if(file.readyState == 200)
{
var lines = file.responseText.split("\n");
//foreach loop to populate select
}
}
}
In your code, you are checking and using files.responseText before you have even sent the Ajax request at files.send(null)
EDIT:
Some more comments regarding your code:
In the createCountriesList function, you create file and assign
it a value by calling requestAjax. You then pass it to
writeDropDownList function, where you assign it a value again by
calling requestAjax. You see that this is redundant? There is no
need to create file in createCountriesList and pass it as an
argument. Create it just once in writeDropDownList.
in writeDropDownList you call upload.requestAjax(). What is
upload. I don't see you initializing upload anywhere. Do you mean
to call base.requestAjax()?
you have a function base.OnReadyStateChange but at no point are you
telling your AJAX request to call that function when state changes. See the code I posted above. The function I added called
requestComplete does that, and I tell the AJAX request to call it using file.onreadystatechange = requestComplete;
You set method to GET, yet you are not passing any GET values in your URL
in file.open(method, path, true);, path is supposed to be the URL of the script the AJAX request will call. You have set path to ../includes/_notes/countries.txt. An AJAX request cannot call a .txt file since they do not execute.
I just had a look at the source of your code, and it is all sorts of broken. Please do not use it.
What is countries.txt ? Are you attempting to populate a dropdown with a list of all countries, or some countries depending on user's input?
If the former, there is no need for Javascript / AJAX. You need to add PHP code in your html to populate the select box.
If the latter, your AJAX request should be sending the user input as a GET variable.

Some comments:
Very nice code; it's readable and looks neat.
I'd use a different name than base as namespace - for my liking, the word is too "common" . Chances are that you're going to define a variable base somewhere and it will break.
To create HTML from JavaScript, first create a small example in pure HTML to see how it should look like. After that, create a script which produces the same HTML using document.createElement().
Look at frameworks like jQuery or Prototype because they make many boring tasks much more simple.

Appending to External Browser Window

I have a Windows app that contains a browser control that loads pages from my website. However, due to the Windows app, I cannot debug Javascript in the usual ways (Firebug, console, alerts, etc).
I was hoping to write a jQuery plug-in to log to an external browser window such that I can simply do something like:
$.log('test');
So far, with the following, I am able to create the window and display the templateContent, but cannot write messages to it:
var consoleWindow;
function getConsoleWindow() {
if (typeof (consoleWindow) === 'undefined') {
consoleWindow = createConsoleWindow();
}
return consoleWindow;
}
function createConsoleWindow() {
var newConsoleWindow = window.open('consoleLog', '', 'status,height=200,width=300');
var templateContent = '<html><head><title>Console</title></head>' +
'<body><h1>Console</h1><div id="console">' +
'<span id="consoleText"></span></div></body></html>';
newConsoleWindow.document.write(templateContent);
newConsoleWindow.document.close();
return newConsoleWindow;
}
function writeToConsole(message) {
var console = getConsoleWindow();
var consoleDoc = console.document.open();
var consoleMessage = document.createElement('span');
consoleMessage.innerHTML = message;
consoleDoc.getElementById('consoleText').appendChild(consoleMessage);
consoleDoc.close();
}
jQuery.log = function (message) {
if (window.console) {
console.log(message);
} else {
writeToConsole(message);
}
};
Currently, getElementById('consoleText') is failing. Is what I'm after possible, and if so, what am I missing?

Try adding
consoleDoc.getElementById('consoleText');
right before
consoleDoc.getElementById('consoleText').appendChild(consoleMessage);
If the line you added is the one that fails, then that means consoleDoc is not right, if the next line is the only one that fails then ..ById('consoleText') is not matching up

If I don't close() the document, it appears to work as I hoped.

javascript undefined error, but alert toSource shows the object exists

I grabbed a bit of code to do some paging with jQuery, via Luca Matteis here
Paging Through Records Using jQuery
I've made some edits to the paging script so that I can use the same code to provide paging of different content in different locations on the same site.
For the most part, I think it works, except that I get a jsonObj is undefined error in firebug.
When I use alert(jsonObj.toSource()), I am shown the variables that I am trying to populate, but at the same time, the script dies because of the error.
I can't figure out why I am getting this conflict of 'undefined' and yet I can easily out put the 'undefined' values in an alert. I can even say alert(jsonObj.name), and it will give me that value, but still launch an jsonObj is undefined error.
Here's the code I'm using
var pagedContent = {
data: null
,holder: null
,currentIndex : 0
,init: function(data, holder) {
this.data = data;
this.holder=holder;
this.show(0); // show last
}
,show: function(index) {
var jsonObj = this.data[index];
if(!jsonObj) {
return;
}
var holdSubset='';
for(i=0;i<=4; i++){
jsonObj=this.data[index+i];
this.currentIndex = index;
if(this.holder=='div#firstList'){
var returnedId = jsonObj.id;
var returnedName = jsonObj.name;
var calcScore=this.data[index+i].score/this.data[0].score*100;
var resultInput="<div ' id='"+returnedId+"'><div class='name'>"+returnedName+"</div><div class='score'><div style='width:"+calcScore+"%;'></div></div>";
}
if(this.holder=='div#secondList'){
var name=jsonObj.name;
var city=jsonObj.city;
var region=jsonObj.state;
var resultInput='<li><div>'+name+'</div<div>'+city+'</div><div>'+region+'</div></li>';
}
holdSubset= holdSubset+resultInput;
}
jQuery(this.holder).html('<br/>'+holdSubset);
if(index!=0){
var previous = jQuery("<a>").attr("href","#").click(this.previousHandler).text("< previous");
jQuery(this.holder).append(previous);
}
if(index+i<this.data.length){
var next = jQuery("<a style='float:right;'>").attr("href","#").click(this.nextHandler).text("next >");
jQuery(this.holder).append(next);
}
}
,nextHandler: function() {
pagedContent.show(pagedContent.currentIndex + 5);
return false;
}
,previousHandler: function() {
pagedContent.show(pagedContent.currentIndex - 5);
return false
}
};
I call the function like this
pagedContent.init(json.users.locations, 'div#secondList');
The json looks like this
{"locations" : [ {"id":"21319","name":"Naugatuck American Legion","city":"Ansonia","region":"Connecticut"},{"id":"26614","name":"Studio B789","city":"Acton","region":"Maine"},{"id":"26674","name":"Deering Grange Hall","city":"Bailey Island","region":"Maine"},{"id":"27554","name":"Accu Billiards","city":"Acushnet","region":"Massachusetts"}]}

I may have found the problem with your code:
for(i=0;i<=4; i++){
jsonObj=this.data[index+i];
(...)
When you call show(0) you set index to 0. You expect a fixed number of items in the array (5 in the range [0..4]) but there are only 4 locations in your data.

If you are using console.log to trace the problems in firebug you might find that it is a problem with firebug. Try just running console.log on it's own.
If it is a problem with firebug try updating it. There are some development versions around which might fix the problem.
I had a similar problem and fixed it by doing the above.
