Hi guys I've got a problem with parsing csv files in javascript. The following code is only used on load the HTML Page but I don't know why. Does somebody have got an idea?
Many thanks in advance!
<script>
$(function test() {
Papa.parse("lockedDevices.csv", {
download: true,
complete: function(results) {
console.log("Remote file parsed!", results.data);
$.each(results.data, function(i, el) {
var row = $("<tr/>");
if(el[0] == "Status")
var color =" bgcolor='lightgrey'>"
if(el[0] == "Free"&&el[4]==" "&&el[5]==" ")
var color = " bgcolor='lightgreen'>";
if(el[0] == "Locked")
var color = " bgcolor='red'>";
if(el[0] == 'Free' && el[5]!=' ')
var color = " bgcolor='yellow'>";
$.each(el, function(j, cell) {
if (cell !== ""){
row.append($('<td'+ color).text(cell));
}
});
$("#lockedDevicesBox tbody").append(row);
});
}
});
})
setInterval(test(),1000);
</script>
You have assigned a named function to doc ready block and you are also trying to call run it in setInterval.
Instead i would say you put the function in the global scope and call it in doc ready within setInterval:
function test(){
// test code
}
$(function(){
setInterval(test, 1000);
});

I'm trying to get the Body in Outlook and then update/set it with categories. My issue is this - when I debug it - it works fine. But when I don't debug from function to function - it gets all the way to the last function and just stops - updateBody(). What's really strang is if I remove the breakpoints on each function and just set a breakpoint on last function - never gets hit, but console will write out "Starting update body". All the console.logs are writing out data as expected. Not sure what is going on. Appreciate any help! Thanks.
"use strict";
var item;
var response;
var tags;
var updatedBody;
Office.initialize = function () {
$(document).ready(function () {
// The document is ready
item = Office.context.mailbox.item;
debugger;
getBodyType();
});
}
function getBodyType() {
item.body.getTypeAsync(
function (resultBody) {
if (resultBody.status == Office.AsyncResultStatus.Failed) {
write(resultBody.error.message);
} else {
response = resultBody;
console.log('Successfully got BodyType');
console.log(response.value);
getCategories();
}
});
}
function getCategories() {
tags = "";
// Successfully got the type of item body.
// Set data of the appropriate type in body.
item.categories.getAsync(function (asyncResult) {
if (asyncResult.status === Office.AsyncResultStatus.Failed) {
console.log("Action failed with error: " + asyncResult.error.message);
} else {
var categories = asyncResult.value;
console.log("Categories:");
categories.forEach(function (item) {
var tag = item.displayName;
tags += '#' + tag.replace(/\s/g, "") + ' ';
});
console.log('Successfully got tags');
console.log(tags);
getBody();
}
});
}
function getBody() {
var body = "";
updatedBody = "";
console.log("Starting get body");
if (response.value == Office.MailboxEnums.BodyType.Html) {
item.body.getAsync(
Office.CoercionType.Html,
{ asyncContext: "This is passed to the callback" },
function (result) {
//Replace all the # tags and update again.
body = result.value.replaceAll(/#(\w)+/g, "").trimEnd();
var domParser = new DOMParser();
var parsedHtml = domParser.parseFromString(body, "text/html");
$("body", parsedHtml).append("<div>" + tags + "</div>");
var changedString = (new XMLSerializer()).serializeToString(parsedHtml);
if (changedString != "") {
updatedBody = changedString;
}
console.log(updatedBody);
updateBody();
});
}
}
function updateBody() {
console.log("Starting update body");
item.body.setAsync(
updatedBody,
{ coercionType: Office.CoercionType.Html },
function (result2) {
console.log("Body updated");
});
}
Image - With breakpoints on each function - works as expected
Image - Without breakpoints - gets to updateBody() function.
But the string updatedBody isn't logged. It somehow skips over that
even though it's called before updateBody() on getBody()
Image - Same code run via Script Lab - works just fine as well.
I am beginner webdeveloper.
I have this function:
function showRalColors() {
const getHex = ral => rals[ral];
$(".ral").each(function () {
var color = $(this).data("id");
$(this).css('background-color', getHex(color));
});
$("div.material-thumb.mini-specialColorDiv.ral").each(function () {
var color = $(this).html();
if (color != undefined) {
console.log(1);
$(this).css('background-color', getHex(color));
$(this).html(' ' + color);
}
});
}
This function work fine. The problem is with " ". Always when I run this function, I have additional " " (5x nbsp). I need MAX 5
How can I repair it?
Please help me?
Actually the codes you are using is generating spaces itself so simply remove and use like below:
$(this).html(color);
and for sapcing use
$(this).css('padding-left', '5px');
I am trying to get the file input preview working.
I have a jquery script which works fine when I call the function normally.
$('#images').on("change", previewImages);
This works.
But when I put the call to the same function differently like following
$('#images').on("change", function(){
previewImages();
});
This doesn't work.
I need to write an if else statement to call a different function on else.
Valid question
Reason: this happens because of this which refers to file element when you are using first approach but in case of second approach this is referring to window element in which it is called. So pass this to function and your question is solved.
$('#images').on("change", function(e) {
/* issue is with this */
previewImages(e, this);
});
var count = 0;
function previewImages(evt, cur) {
var $fileUpload = $("input#images[type='file']");
count = count + parseInt($fileUpload.get(0).files.length);
if (parseInt($fileUpload.get(0).files.length) > 7 || count > 6) {
alert("You can only upload a maximum of 6 files");
count = count - parseInt($fileUpload.get(0).files.length);
evt.preventDefault();
evt.stopPropagation();
return false;
}
$("#taskbar").css("height", "auto");
var $preview = $('#preview').empty();
if (cur.files) $.each(cur.files, readAndPreview);
function readAndPreview(i, file) {
// if (!/\.(jpe?g|png|gif|mp4)$/i.test(file.name)){
// return alert(file.name +" is not an image");
// }
var reader = new FileReader();
$('#preview img').addClass('img-responsive');
$(reader).on("load", function() {
$preview.append($("<img/>", {
src: this.result,
height: 100
}));
});
reader.readAsDataURL(file);
}
}
Create a prePreviewImages function, and use that in your first approach. Inside that function, use the if-statement and call previewImages() or your other function.
The following should do..
$('#images').change(function(e) {
if(e == "some condition"){ // if else goes here
previewImages();
}else {
SomeOtherFun();
}
});
Both ways seem to work for me on the JSFiddle. Are you sure it is not a
browser compatibility issue?
If not are you getting errors logged in the console under developer tools?
I have the following code:
<script>
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
window.setInterval(function(){
refreshChat();
}, 2000);
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
}
});
</script>
Right now, the refreshChat function calls an ajax script every 2 seconds. When you have entered a message and press enter, it calls a different ajax script. What I would like it to do, is call both functions at the same time. So the script calls the sendMessage function first and refreshes afterwards.
How can I do this? I have already tried changing it to:
<script>
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();refreshChat();
}
});
</script>
But this only enters the message first, and it only refreshes on the second keypress (enter). I would like to thank everybody beforehand on helping me out.
This is actually an illusion. Both functions are being called, but the chat window is refreshing before the chat message is able to save them.
To fix this, you should refresh the chat window only once the new message has been successfully saved:
function refreshChat() {
// Removed for brevity
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
// Now, this will only be called once the ajax is complete
refreshChat();
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
// I removed the refreshChat() call from here and moved it
// into the $.get() callback above ^^
}
});
As you can see, I moved your refreshChat() method to now be called from within the jQuery $.get() callback.
Have you tried using callbacks, that may be what you need?

MY WORKING AWNSER
Considering for what i asked, i have marked Wes Foster's awnser as correct. What made it work for me is also applying a promises after the get function. This way, the ajax script get's called twice as needed. I hope it will help someone in the future. (Look at me... travelling through time...). You will find my code underneath:
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
refreshChat();
}).done(refreshChat);
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
}
});
I wrote the function below to get the length of a listbox with the id courselessons. The problem is that when I comment the alert() the function changecheckbox works only once.
If I remove the alert it works fine. But I don't want to have an alert on every single click.
The selOpts shows correct content only for the first time.
JavaScript:
function changecheckbox() {
//alert("function called...");
var selOpts = document.getElementById("courselessons").length();
alert(selOpts);
if (selOpts > 0) {
$('#taskassignment').prop('disabled', false);
}
else {
$('#taskassignment').prop('disabled', true).prop("checked", false);
}
}
function addItem() {
if (seltask == undefined || seltask.length === 0) {
return;
}
var lessonsDropdown = $('#courselessons');
lessonsDropdown.empty();
$("#tasks option:selected").appendTo("#coursetasks");
$("#coursetasks option").attr("selected", false);
if (seltask.length > 0) {
cacheToken = new Date().getTime();
// retrieve data using a Url.Action() to construct url
$.getJSON('#Url.Action("AddTaskToCourse")', {
task: seltask,
lesson: lesson,
_: cacheToken
});
$.getJSON('#Url.Action("UpdateLessonInCourse")', {
_: cacheToken
}).done(function (data) {
//re-enable tasks drop down
//for each returned tasks
$.each(data, function (i, lessons) {
//Create new option
var test = $('<option />').html(lessons);
//append tasks taskss drop down
lessonsDropdown.append(test);
});
seltask = null;
});
}
changecheckbox();
}
HTML:
<button type="button" id="btnAdd" onclick="addItem(); changecheckbox();">Add Item</button>
Try using like this,
function changecheckbox() {
//alert("function called...");
var selOpts = $("courselessons").find('option').length;
if (selOpts > 0) {
$('#taskassignment').prop('disabled', false);
}
else {
$('#taskassignment').prop({'disabled':true, 'checked':false});
}
}
or you can do like this ,
$("#btnAdd").click(function(e){
e.preventDefault();
var selOpts = $("#courselessons").find('option').length;
if (selOpts > 0) {
$('#taskassignment').prop('disabled', false);
}
else {
$('#taskassignment').prop({'disabled':true, 'checked':false});
}
});
The code inside addItem() is making a GET request to a resource asynchronously. This means the code which comes after this function to be execute will not wait for its execution to get complete.
When I uncomment the alert it works fine.
That is because as the alert() is built in, it halts the execution of script until user interaction. This gave the time addItem() needs and everything seems to work.
Fortunately, there are solutions available to handle this situation.
Promise.
Rearrange your code to work with callbacks.
Under the covers, $.getJSON is shorthand for making a GET request using ajax with datatype = 'json'and it returns a promise object which basically tells that please wait honey, i will give you something which could be a success or a failure but sometime later.
So yes, you can easily call the function inside the done().
NOTE: These things have been explained pretty well on web so i will not reinvent the wheel :)
Keeping the things simple...
function addItem() {
// Rest of the code...
if (seltask.length > 0) {
cacheToken = new Date().getTime();
// retrieve data using a Url.Action() to construct url
$.getJSON('#Url.Action("AddTaskToCourse")', {
task: seltask,
lesson: lesson,
_: cacheToken
});
$.getJSON('#Url.Action("UpdateLessonInCourse")', {
_: cacheToken
}).done(function (data) {
//re-enable tasks drop down
//for each returned tasks
$.each(data, function (i, lessons) {
//Create new option
var test = $('<option />').html(lessons);
//append tasks taskss drop down
lessonsDropdown.append(test);
});
seltask = null;
changecheckbox();
});
}
}
After this setup, you should remove the changecheckbox() call from the button onclick otherwise it would make it execute twice.
Remove the options, and take the id of select <select id="mySelect"> example:
var selOpts = document.getElementById("mySelect").length;
and your code will be
function changecheckbox() {
//alert("function called...");
var selOpts = document.getElementById("courselessons").length;
if (selOpts > 0) {
$('#taskassignment').prop('disabled', false);
}
else {
$('#taskassignment').prop('disabled', true);
$("#taskassignment").prop("checked", false);
}
}
