why is my script not printing text when i click the button - javascript

<!DOCTYPE html>
<html>
<head>
<title>WhiteList</title>
</head>
<body>
<h1>Hello stranger lets see if you are on the list!!</h1>
<input id="1" value="type here" placeholder="type here">
<button onclick="click()">Check</button>
<br>
<p id=stuff></p>
<script type="text/javascript">
function click(){
var name = document.getElementById('1').value;
if (name == "tijmen"){
document.getElementById("stuff").innerHTML = "<p>hey you are on the list welcome</p>"
} else{
document.getElementById("stuff").innerHTML = "<p>sorry you are not on the list</p>"
}
}
</script>
</body>
</html>
so this is the code, there are no errors. but the problem is that the text won't print when i insert my name and click the button.... i realy cant seem to find the problem.

Try add onclick to the JavaScript:
<body>
<h1>Hello stranger lets see if you are on the list!!</h1>
<input id="1" value="type here" placeholder="type here">
<button id="btn">Check</button>
<br>
<p id=stuff></p>
<script type="text/javascript">
document.getElementById("btn").onclick = function() {
var name = document.getElementById('1').value;
if (name === "tijmen"){
document.getElementById("stuff").innerHTML = "<p>hey you are on the list welcome</p>"
} else {
document.getElementById("stuff").innerHTML = "<p>sorry you are not on the list</p>"
}
}
</script>
</body>

Problem here is click is defined as a click action so the engine is thinking you are calling the click of the button. Simple test shows what the browser sees.
<button onclick="console.log(click)">Check</button>
What can you do? Change the name, or even better, use addEventListener to bind the event listener.

I cannot get input to work under google app script

I'm writing a web app under google sheets and can't get an input field to work. What am I doing wrong?
everything works but uname is always empty (not undefined).
edit: I'm adding the full code after simplifying it as much as I could.
In the log I get "name" regardless of the input I type in.
In the file code.gs:
function doGet () {
var participant = {};
var templ = HtmlService.createTemplateFromFile('out');
return templ.evaluate();;
}
function formSubmit(name) {
Logger.log("name " + name);
}
In out.html
<!DOCTYPE html>
<html>
<head>
<base target ="_top">
</head>
<body dir="rtl"; background-color: #92a8d1;>
<label> Name 1 </label> <input type="text" id="firstname"><br>
<label> Name 2 </label> <input type="text" id="lastname"> <br><br>
<button type="button" id="send">Send</button>
<script>
document.getElementById("send").addEventListener("click", getData());
function getData(){
var uname = document.getElementById("firstname").value;
google.script.run.formSubmit(uname);
}
</script>
</body>
</html>
You want to retrieve the value of <input type="text" id="firstname"> when the button is clicked.
In your current situation, when you see the log with the script editor, only name is retrieved. This is your current issue.
You want to know the reason of the issue.
If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.
Modification points:
In your script, document.getElementById("send").addEventListener("click", getData()); is used. In this case, when the HTML is loaded, getData() is run by () of getData(). By this, uname becomes "" and "" is sent to formSubmit(uname), then, when you see the log, you see name. And also, in this case, even when the button is clicked, google.script.run.formSubmit(uname); cannot be run. I think that this is the reason of the issue of your script in your question.
In order to avoid this, please modify your script as follows.
Modified script:
From:
document.getElementById("send").addEventListener("click", getData());
To:
document.getElementById("send").addEventListener("click", getData);
By the above modification for your script, when sample is inputted to "Name 1" and click "Send" button, you can see name sample at the log with the script editor.
Reference:
addEventListener()
If I misunderstood your question and this was not the result you want, I apologize.
Here's an example form that you can probably use to accomplish your needs. This form is used as a simple receipt collection system. You can actually take and upload images from a mobile device with it. I also has text and button input types and upload a form node.

var sh=SpreadsheetApp.getActive().getSheetByName("Sheet1");
sh.getRange(sh.getLastRow()+1,1).activate();
}
function uploadTheForm(theForm) {
var rObj={};
rObj['vendor']=theForm.vendor;
rObj['amount']=theForm.amount;
rObj['date']=theForm.date;
rObj['notes']=theForm.notes
var fileBlob=theForm.receipt;
var fldr = DriveApp.getFolderById(receiptImageFolderId);

rObj['filetype']=fileBlob.getContentType();
Logger.log(JSON.stringify(rObj));
var cObj=formatFileName(rObj);
Logger.log(JSON.stringify(cObj));
var ss=SpreadsheetApp.openById(SSID);
ss.getSheetByName('Sheet1').appendRow([cObj.date,cObj.vendor,cObj.amount,cObj.notes,cObj.file.getUrl()]);

rObj.file.setName(name);
}else{
throw('Invalid or No File in formatFileName() upload.gs');
}
return rObj;
}
function doGet() {
var output=HtmlService.createHtmlOutputFromFile('receipts').setTitle('thehtml');
return output.setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL).addMetaTag('viewport', 'width=360, initial-scale=1');

return {date:datestring};

java script capitalize letters in a input form

Hey guys what am I doing wrong here?? I'm sorry if this has been posted before, but I couldn't find a good example with a form input.
Thank you.
I really don't understand why output.value.toUpperCase() doesn't work, or toUpperCase(output.value) wouldn't work.
<html>
<head>
<link href="https://fonts.googleapis.com/css?family=Barlow" rel="stylesheet">
</head>
<body>
<h1 id="title">Capitalize a String</h1>
<form>
<input type="text" id="entry" placeholder="Enter a string to be capitalized">
</form>
<h1 id="title">Output</h1>
<form>
<input type="text" id="output" placeholder="Output">
</form>
<div id="goBtn">
<h1 id="goBtnText">
GO
</h1>
</div>
</body>
</html>
var goBtn = document.getElementById('goBtn');
var entry = document.getElementById('entry');
var output = document.getElementById('output');
goBtn.addEventListener('click', capitalizeStr);
function capitalizeStr () {
output.value = entry.value;
return output.value.toUpperCase();
}
You will need to do
function capitalizeStr () {
output.value = entry.value.toUpperCase();
}
Calling output.value.toUpperCase() does not change the output.value property, it just returns a new string (and the value returned by an event listener is ignored).

Show what the user typed in the body

I have a code and I want that after the user type something in the textfield and press enter, what he typed appears on the screen. But I'm not being able to do that, I'd like some help here.

it only adds one value to the screen, to put more than one, do I need
to create an array
You had the main components working. Namely, you were updating the screen. To have it update only on enter, simply put the code in the keypress handler
To append the value to the screen(in the case of more than one enter), concatenate the current innerHTML with the value
$(document).ready(function() {
$("p").click(function() {
$(this).hide();
});
});
$('#userInput').keypress(function(e) {
if (e.which == 13) {
var userInput = document.getElementById('userInput').value;
var innerHTML = document.getElementById('userMsg').innerHTML;
innerHTML = innerHTML || '';
document.getElementById('userMsg').innerHTML += innerHTML + userInput;
}

insert text to selected Textbox use Javascript

I have 2 textBox and 1 button!
I want to insert text to one of these textboxs. When I click to textbox_1 and click button, mytext will appear at textbox_1. When I click to textbox_2 and click button, mytext will appear at textbox_2.
How can I do this by using JavaScript?
Please help me! I'm new on JavaScript!
put id's of the two textboxes as textbox_1 and textbox_2 and put onclick='onCLickButton();' on the <button> tag
and write the following code in the script
var text_to_be_inserted = "sample";
function onCLickButton(){
document.getElementById("textbox_1").value='';
document.getElementById("textbox_2").value='';
if(document.getElementById("textbox_1").focused){
document.getElementById("textbox_1").value=text_to_be_inserted;
}
else if(document.getElementById("textbox_2").focused){
document.getElementById("textbox_2").value=text_to_be_inserted;
}
else{
// do nothing
}
}
Edited
Please accept my apologies actually I am used to use these functions as I have my own js file having these functions.
please add onfocus='onFocusInput(this);' in the <input> tags and add the following code in the script
function onFocusInput(object){
document.getElementById("textbox_1").focused=false;
document.getElementById("textbox_2").focused=false;
object.focused = true;
}
<html>
<head>
<script type="text/javascript">
var index = false;
var text = "This text shifts to text box when clicked the button";
function DisplayText(){
if(!index){
document.getElementById("txt1").value = text;
document.getElementById("txt2").value = "";
}
else{
document.getElementById("txt2").value = text;
document.getElementById("txt1").value = "";
}
index = index ? false : true;
}
</script>
</head>
<body>
<input type="text" id="txt1"/>
<input type="text" id="txt2"/>
<input type="button" value="Change Text" onclick="DisplayText()"/>
</body>
</html>
Take a look at the onFocus() attribute for the INPUT tag - and think about keeping track of what was last given the focus. I'm being a little vague as this sounds a lot like homework.
It isn't the prettiest / most delicate solution, but it works and you can build off it to fulfill your needs.
<script>
var field = 0;
function addText(txt){
if(field === 0) return false;
field.value = txt;
}
</script>
For a form such as
<form>
<input type="text" name="box1" id="box1" onfocus="field=this;" />
<input type="text" name="box2" id="box2" onfocus="field=this;" />
<input type="button" onclick="addText('Hello Thar!');" />
</form>

Getting rid of Value attribute of a textBox when using clone method in jQuery

I'm having a problem with this form I'm working on. Whenever I add, or refresh the page, the values are still there. I believe this is because the clone method copies the value attribute from the textBox. Is there any way I can get rid of them when I add another textBox?
<html>
<head>
<title>JQuery Example</title>
<script type="text/javascript" src="jquery-1.4.js"></script>
<script type="text/javascript">
function removeTextBox()
{
var childCount = $('p').size() //keep track of paragraph childnodes
//this is because there should always be 2 p be tags the user shouldn't remove the first one
if(childCount != 2)
{
var $textBox = $('#textBox')
$textBox.detach()
}
}
function addTextBox()
{
var $textBox = $('#textBox')
var $clonedTextBox = $textBox.clone()
//document.getElementById('textBox').setAttribute('value', "")
$textBox.after($clonedTextBox)
}
</script>
</head>
<body>
<form id =
method="POST"
action="http://cs.harding.edu/gfoust/cgi-bin/show">
<p id= "textBox">
Email:
<input type = "text" name="email" />
<input type ="button" value ="X" onclick = "removeTextBox()"/>
</p>
<p>
Add another email
</p>
<input type="submit" value="submit"/>
</form>
</body>
</html>
The Following addition should work:
var $clonedTextBox = $textBox.clone();
$($clonedTextBox).val('');
