I'm making an application of a list of races in a table, this information is gotten from a JSON api. Upon selecting a race in a table I need a window to pop up with the name of the race in the url address bar, so something like asp?=race_name at the end.
How would I go about completing this?
I've looked this up but can't seem to find an answer, my guess is I'm googling the wrong thing as I'm not good at explaining
for (let i = 0; i < jsonObj.length; i++) {
document.getElementById(jsonObj[i].id).onclick = function () {
var newWin = window.open("","","width=700,height=700");
newWin.onload = function () {
var doc = newWin.document; // Create new document in window
var raceName = document.createElement('h3');
var distance = document.createElement('p');
var location = document.createElement('p');
var curPos = document.createElement('p');
var difference = document.createElement('p');
raceName.textContent = jsonObj[i].race_name;
distance.textContent = jsonObj[i].distance;
location.textContent = jsonObj[i].venue_name;
doc.body.appendChild(raceName);
doc.body.appendChild(distance);
doc.body.appendChild(location);
}
}
Here the window pops up and includes the correct information, I now just need to include code that would update the url address to include race name.
When I want to read the data of my Firebase, nothing appears.
I have tried to read the data using a script for this.
This is my HTML code:
<html>
<head>
<title>Javascript Firebase</title>
Humidity: <humidity></humidity><br>
Clock: <clock></clock><br>
</head>
<body>
and this is my script:
<script type="text/javascript">
var database = firebase.database('javascript-firebase-6567d');
var h document.querySelector('humidity');
var c = document.querySelector('clock');
var pad = function(x){
return x < 10 ? '0' +x : x;
}
var ShowClock = function() {
var d = new Date();
var h = pad(d.getHours());
var m = pad (d.getMinutes());
var s = pad (d.getSeconds());
c.innerHTML = [h,m,s].join(':');
}
setInterval(ShowClock,1000);
var myRef = Firebase('https://javascript-firebase-6567d.firebaseio.com/rooms');
myRef.on('child_changed',function(snapshot){
data = snapshot.val();
h.innerHTML = data.humidity;
});
</script>
The results that I hope is to see the changes that the child "humidity" shows but currently I can not see the results of the clock or the humidity
This code:
myRef.on('child_changed',function(snapshot){
data = snapshot.val();
h.innerHTML = data.humidity;
});
The child_changed event only fires when the data in the location changes. If you're trying to show the current child nodes under a location, you'll want to use child_added:
myRef.on('child_added',function(snapshot){
data = snapshot.val();
console.log(data);
});
The child_added fires immediately after attaching the listener for any existing child node, and then subsequently for any new nodes that are added.
This might be easy for some, but I'm struggling to make this work.
I created a modal that has title, subject (input area) and timestamp when you click submit.
I would like to output title, subject, and time posted as a list item <li></li>.
var main = function(){
$('.btn-primary').click(function(){
var title = $('#message-title').val();
var post = $('#message-text').val();
$('<li>').text(post).prependTo('.livefeed');
var currentTime = new Date();
var n = currentTime.toLocaleDateString();
document.getElementById("timestamp").innerHTML = n
$('#message-text').val();
});
}
$(document).ready(main);
Here is the Screenshot
try something like this
JAVASCRIPT
$('.btn-primary').click(function(){
var title = $('#message-title').val();
var post = $('#message-text').val();
var currentTime = new Date();
var n = currentTime.toLocaleDateString();
$('ul').append('<li>'+title+' '+post+' '+n+'</li>');
});
I'm using this code to get a blob passed to a function:
function submit(e){
var arrayBlob = e.parameter.arrayBlob;
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
This is the error I get:
Execution failed: TypeError: Can not find getDataAsString function in
the Blob object.'arrayBlob'
How do I get the string value of this blob?
Here is my code:
function showList(folderID) {
var folder = DocsList.getFolderById(folderID);
var files = folder.getFiles();
var arrayList = [];
for (var file in files) {
file = files[file];
var thesesName = file.getName();
var thesesId = file.getId();
var thesesDoc = DocumentApp.openById(thesesId);
for (var child = 0; child < thesesDoc.getNumChildren(); child++){
var thesesFirstParagraph = thesesDoc.getChild(child);
var thesesType = thesesFirstParagraph.getText();
if (thesesType != ''){
var newArray = [thesesName, thesesType, thesesId];
arrayList.push(newArray);
break;
}
}
}
arrayList.sort();
var result = userProperties.getProperty('savedArray');
arrayList = JSON.stringify(arrayList);
var arrayBlob = Utilities.newBlob(arrayList);
Logger.log("arrayBlob #1 = " + arrayBlob.getDataAsString()); // Here it`s OK
var mydoc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setWidth(550).setHeight(450);
var panel = app.createVerticalPanel()
.setId('panel');
panel.add(app.createHidden('arrayBlob', arrayBlob));
var label = app.createLabel("Selecione os itens desejados").setStyleAttribute("fontSize", 18);
app.add(label);
arrayList = JSON.parse(arrayList);
panel.add(app.createHidden('checkbox_total', arrayList.length));
for(var i = 0; i < arrayList.length; i++){
var checkbox = app.createCheckBox().setName('checkbox_isChecked_'+i).setText(arrayList[i][0]);
Logger.log("arrayList[i][0] = " + arrayList[i][0]);
Logger.log("arrayList[i] ====> " + arrayList[i]);
panel.add(checkbox);
}
var handler = app.createServerHandler('submit').addCallbackElement(panel);
panel.add(app.createButton('Submit', handler));
var scroll = app.createScrollPanel().setPixelSize(500, 400);
scroll.add(panel);
app.add(scroll);
mydoc.show(app);
}
function submit(e){
var arrayBlob = e.parameter.arrayBlob;
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
// Continues...
}
I'd like the solution worked with more than one user simultaneous using the script.
Update:
Add a global variable OUTSIDE of any function:
var arrayBlob = Utilities.newBlob("dummy data");
function showList(folderID) {
Code here ....
};
Check that the code has access to the blob:
function submit(e){
Logger.log("arrayBlob.getDataAsString(): " + arrayBlob.getDataAsString());
//More Code . . .
}
This solution eliminates the need of embedding a hidden element in the dialog box with a value of the blob.
You won't need this line:
panel.add(app.createHidden('arrayBlob', arrayBlob));
There are other changes I'd make to the code, but I simply want to show the main issue.
Old Info:
In the function showList(), the method getDataAsString() works on the blob named arrayBlob.
Logger.log("arrayBlob #1 = " + arrayBlob.getDataAsString()); // Here it`s OK
In the function, submit(), the same method does not work.
var arrayBlob = e.parameter.arrayBlob;
In the function showList(), the code is assigning a newBlob to the variable arrayBlob. So arrayBlob is available to have the getDataAsString() method used on it.
var arrayBlob = Utilities.newBlob(arrayList);
In the function, submit(), you are trying to pass the arrayBlob blob variable into the submit() function, and reference it with e.parameter.
If you put a Logger.log() statement in the submit() function.
function submit(e){
Logger.log('e: ' + e);
Logger.log('e.parameter` + e.parameter);
var arrayBlob = e.parameter.arrayBlob;
Those Logger.log statements should show something in them. If there is nothing in e.parameter, then there is nothing for the .getDataAsString() to work on.
It looks like you are putting the arrayBlob into a hidden panel.
panel.add(app.createHidden('arrayBlob', arrayBlob));
But when the object is getting passed to the submit(e) function, the arrayBlob might not be getting put into that object.
So, what I'm saying is, the:
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
Line may be perfectly good, but there is no arrayBlob there to work on. This hasn't fixed your problem, but do you think I'm understanding part of what is going on?
I'm not sure why you are using Blob's here at all, you could simply work with JSON instead.
However, if you have a reason to use Blobs, you can pass the JSON data through your form and create the Blob in your handler, as the modified code below does:
function showList(folderID) {
var folder = DocsList.getFolderById(folderID);
var files = folder.getFiles();
var arrayList = [];
for (var file in files) {
file = files[file];
var thesesName = file.getName();
var thesesId = file.getId();
var thesesDoc = DocumentApp.openById(thesesId);
for (var child = 0; child < thesesDoc.getNumChildren(); child++){
var thesesFirstParagraph = thesesDoc.getChild(child);
var thesesType = thesesFirstParagraph.getText();
if (thesesType != ''){
var newArray = [thesesName, thesesType, thesesId];
arrayList.push(newArray);
break;
}
}
}
arrayList.sort();
var result = UserProperties.getProperty('savedArray');
//get JSON data pass through form.
var arrayBlob = JSON.stringify(arrayList);
var mydoc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setWidth(550).setHeight(450);
var panel = app.createVerticalPanel()
.setId('panel');
//include JSON Data in the form.
panel.add(app.createHidden('arrayBlob', arrayBlob));
var label = app.createLabel("Selecione os itens desejados").setStyleAttribute("fontSize", 18);
app.add(label);
panel.add(app.createHidden('checkbox_total', arrayList.length));
for(var i = 0; i < arrayList.length; i++){
var checkbox = app.createCheckBox().setName('checkbox_isChecked_'+i).setText(arrayList[i][0]);
Logger.log("arrayList[i][0] = " + arrayList[i][0]);
Logger.log("arrayList[i] ====> " + arrayList[i]);
panel.add(checkbox);
}
var handler = app.createServerHandler('submit').addCallbackElement(panel);
panel.add(app.createButton('Submit', handler));
var scroll = app.createScrollPanel().setPixelSize(500, 400);
scroll.add(panel);
app.add(scroll);
mydoc.show(app);
}
function submit(e){
var arrayBlob = Utilities.newBlob(e.parameter.arrayBlob);
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
// Continues...
}
In the method you were using originally, the Blob itself was never included in the form, you were simply passing the string "Blob" around.
This is because the function createHidden(name, value); expects two strings as parameters, so it calls ".toString()" on the arrayBlob object, which returns the string "Blob".
I have a javascript function that outputs the date modified of a sharepoint list.
Here is my code:
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var lists = web.get_lists();
var list = lists.getByTitle("Tasks");
ctx.load(list, "LastItemModifiedDate");
ctx.executeQueryAsync(
function() {
var lastmodified = list.get_lastItemModifiedDate();
},
function() {}
);
Which I got from this link. But I am unsure of how to display the output from the function. I tried to display the output in the html tag but still no luck.
Have you tried something like this after you capture the lastmodified date?
// Names are generic and can be changed
var displayElement = document.getElementById("lastModifiedDisplay");
displayElement.innerHTML = lastmodified
document.getElementById
