I am running my website off of squarespace and I have a button that says "DELIVER ME" but when you click it, I want it to say "G.T.F.O" while the next page loads.
I don't have a code for this and need help writing one.
function changeButtonText(DELIVER ME, G.T.F.O.){
if (this.value== "DELIVER ME"){
this.value = "G.T.F.O.";
} else {
this.value = "DELIVER ME";
}
}
changeButtonText();
I want the button to say "DELIVER ME" until you click it, then once you click it the button will say "G.T.F.O."
I want the button to say "DELIVER ME" until you click it, then once you click it the button will say "G.T.F.O."
Given this button:
<input type="button" id="myButton" value="DELIVER ME">
You could do it like this:
const myButton = document.getElementById("myButton");
myButton.addEventListener("click", function() {
this.value = "G.T.F.O."
});
Or, if the button is like this:
<button id="myButton">DELIVER ME</button>
You would do:
const myButton = document.getElementById("myButton");
myButton.addEventListener("click", function() {
this.innerText = "G.T.F.O."
});
function changeText() {
return document.querySelector("#button").innerHTML = "New text";
}
document.addEventListener("click", changeText);
<button type="button" id="button">Text</button>
most of the answer can solve your particular problem but I just want to add more information about selecting htmlElement.
in VanillaJS(pure Javascript) DOM. you can select element with 3 DOM method.
Select by ID's attribute
elem = document.getElementById("id")
Select by class attribute
elem = document.getElementsByClassName("class")
Select by TagName
elem = document.getElementByTagName("Tag")
and 1 more extra way which used.
elem = document.querySelector(selector)
selector can be one of ".class","#id", or "Tags"
Thanks
<button type="button" id="btn" onclick=changeButtonText()>deliver me</button>
<script>
function changeButtonText(){
document.getElementById("btn").innerHTML = "GTFO";
}
</script>

I want to automatically trigger a tap on a button with javascript.
var submitButton = document.getElementsByName('name');
I tried the following and none of them worked.
submitButton.click();
and
const touchEvent = new TouchEvent("touchstart", {
touches: [touch],
view: window,
cancelable: true,
bubbles: true,
});
submitButton.dispatchEvent(touchEvent);
Neither worked.
Document.getElementsByName() returns a NodeList of elements (not a single element).
As far as the event, click should work just fine:
for (const elm of document.getElementsByTagName('button')) {
elm.addEventListener('click', (ev) => console.log(ev.target.textContent));
}
const buttons = document.getElementsByName('name');
for (const button of buttons) {
button.click();
}
<div>
<button name="name">one</button>
<button name="name">two</button>
<button>three</button>
</div>
Add an id to the above button with a onClick function.
Change the
document.getElementsByName('name')
to
document.getElementById('id')
Full Code:
Html:
<button id="btn" onClick="clicked()">
Click me
</button>
JS:
var btn=document.getElementById("btn");
btn.click();
function clicked() {
console.log("Clicked");
}
If you want to trigger multiple buttons with same class:
Html:
<button class="btn" onClick="clicked()">
Click me
</button>
JS:
var btn=document.getElementsByClassName("btn");
btn[0].click();
function clicked() {
console.log("Clicked");
}
For multiple button with same class, the return of the document.getElementsByClassName will return an array of object. In the above example, I have used the first element of that array, but if you want, you can loop through the array and trigger the click event.
document.getElementsByName returns a NodeList Collection of elements with a given name attribute in the document.
So your submitButton will be an array. So you have to dispatch the click event with submitButton[0].click()
var submitButton = document.getElementsByName('name');
submitButton[0].click();
function submitClick() {
console.log('submitClick')
}
<button name="name" onclick="submitClick()">Submit</button>
If I click a button the activeElement is the button.
If I leave an input box the activeElement is the Window.
If I leave an input box by clicking on a button the activeElement is ... both?
Why does the onfocusout event not register the same activeElement as the button?
Is there anyway I can access the click-on-button event from the function call of the inputbox-leave-event? ie can I ask, "Did you leave me for the lousy button?"
<button type="button" onclick = "myFunction()"> button </button><br>
<input type="text" onfocusout= "myFunction()"> </input>
<script>
function myFunction() {
console.log(document.activeElement);
}
</script>
You can add an event listener for the button inside the myFunction()
function myFunction() {
// console.log(document.activeElement);
var btn = document.getElementById("btn");
btn.addEventListener("click", function (event) {
console.log(event);
});
}
<!DOCTYPE html>
<html>
<body>
<button id="btn" type="button">button</button><br>
<input type="text" onfocusout="myFunction()" />
</body>
</html>
The activeElement read-only property of the Document interface returns the Element within the DOM that currently has focus.
Often activeElement will return a HTMLInputElement or HTMLTextAreaElement object if it has the text selection at the time. If so, you can get more detail by using the object's selectionStart and selectionEnd properties.
In addition, it is indeed possible to trigger a button click when leaving the input element, you just need to make sure to handle the onfocusout function, and use the code inside the function to trigger the click event, you can refer to here.
function onMouseUp(e) {
const activeTextarea = document.activeElement;
const selection = activeTextarea.value.substring(
activeTextarea.selectionStart, activeTextarea.selectionEnd
);
const outputElement = document.getElementById('output-element');
const outputText = document.getElementById('output-text');
console.log({ id: activeTextarea.id, selection});
}
const textarea1 = document.getElementById('textarea1');
const textarea2 = document.getElementById('textarea2');
textarea1.addEventListener('mouseup', onMouseUp, false);
textarea2.addEventListener('mouseup', onMouseUp, false);
<textarea name="textarea1" id="textarea1" rows="7" cols="40">This is Text Area One.</textarea>
<textarea name="textarea2" id="textarea2" rows="7" cols="40">This is Text Area Two</textarea>
The relatedTarget in the event will show you where it's leaving to
of course, you have to use addEventListener to access the event in the first place
But I think this demonstrates what you want to see
it'll definitely tell you
"Did you leave me for the lousy button?"
const button = document.querySelector('button')
const input = document.querySelector('input')
function buttonHandler(e) {
console.log('button clicked');
}
function inputHandler(e) {
console.log('leaving input for', e.relatedTarget?.tagName || 'window');
}
input.addEventListener('focusout', inputHandler);
button.addEventListener('click', buttonHandler);
<button type="button"> button </button><br>
<input type="text"> </input>
I try to add an EventListener to a button. Here is my code:
<button data-id="g/incider/perry">Kaufen</button>
<script type="text/javascript">
var button = document.getElementById('g/incider/perry');
button.addEventListener(
'click',
function() {
alert("test");
},
false
);
</script>
But the alert is not shown when the button is clicked.
I believe that you are new to the Javascript so will help you out here.
As you see your element <button data-id="g/incider/perry">Kaufen</button> has data-id attribute mentioned but you want to select the element by id as per your code document.getElementById()
Solution: document.getElementById() as the property named it searches for the id attribute in the element so you need to provide id to the element
<button id="uniqueID">Kaufen</button>
and then selecting it with,
const button = document.getElementById('uniqueID');
To Learn more about selectors in JavaScript you can check This Link
Try id instead of data-id.
<button id="g/incider/perry">Kaufen</button>
<script type="text/javascript">
var button = document.getElementById('g/incider/perry');
button.addEventListener(
'click',
function() {
alert("test");
},
false
);
</script>
If you want to use data-id for some reason you have to use the getAttribute() function to get the value of an attribute otherwise just stick with id.
const button = document.getElementById('g/incider/perry');
button.addEventListener('click', () =>
alert("test");
}, false);
<button id="g/incider/perry">Kaufen</button>
Hey i want to create a button like this:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<input type="button" value="click-me" id="myButton" onclick="myFunction()">
</body>
</html>
but i want to create from javascript, and i'm doing something really wrong cause my button does not seem
var MyButton = document.createElement("BUTTON");
MyButton.id = "Mybuttonid";
MyButton.className = "MyButtonclass";
MyButton.onclick("myFunction()");
Div.appendChild(MyButton); //i have others things working in this "Div" only this button doesn't appear
You've a misuse of onclick in the posted code, if you check the console you could notice the following message :
"Uncaught TypeError: MyButton.onclick is not a function"
To attach the click event using the onclick it should be :
MyButton.onclick = myFunction;
Else it will be better to attach the event using addEventListener() instead like :
MyButton.addEventListener("click", myFunction);
Hope this helps.
var Div = document.getElementById("my_div");
var MyButton = document.createElement("BUTTON");
MyButton.id = "Mybuttonid";
MyButton.className = "MyButtonclass";
MyButton.addEventListener("click", myFunction);
Div.appendChild(MyButton);
function myFunction(){
alert('test');
}
<div id="my_div"></div>
You are doing it wrong because Button does not exists(but MyButton exists).
Instead of :
var MyButton = document.createElement("BUTTON");
MyButton.id = "Mybuttonid";
MyButton.className = "MyButtonclass";
MyButton.onclick("myFunction()");
Div.appendChild(MyButton);
Use addEventListener to add click event to the button; And change Div.appendChild(button); to Div.appendChild(MyButton);
function myFunction(){
alert("here");
}
var Div = document.getElementById('div');
var MyButton = document.createElement("button");
MyButton.id = "Mybuttonid";
MyButton.innerHTML ="CLICK ME"
MyButton.className = "MyButtonclass";
MyButton.addEventListener("click", myFunction, false);
Div.appendChild(MyButton); //i have others think working in this "Div" only this button doesn't appear
<div id="div">
</div>
In both HTML and Javascript, you are declaring your onclick function the wrong way. Instead of
<input type="button" value="click-me" id="myButton" onclick"myFunction()">
it should be
<input type="button" value="click-me" id="myButton" onclick="myFunction()">
Which means that this piece of code in Javascript here:
MyButton.onclick("myFunction()");
Should be
MyButton.onclick = function(){ myFunction() };
By doing this and solving the typo that other users mentioned, it should work just fine.
I'm working on coding javascript and I'm kind of a noob here. This is my code:
<button onclick="test()">Click Me!</button>
<script>
function test()
{
var btn = document.createElement("BUTTON");
var name = document.createTextNode("Button");
btn.appendChild(name);
document.body.appendChild(btn);
btn.onclick = ex();
}
ex()
{
}
</script>
I want to do two things, and I can't seem to find a solution. I want to:
use the function "ex" to remove the button that says "Click Me!"
assign btn.onclick to the button I just created.
Can anyone help me with this?
EDIT: Although all you guys are trying to help me, I'm not sure you guys are quite understanding the question fully. So, expanding on the first request:
I want to use the function "ex" to delete the button "Click Me!" I want this button to be deleted from the page, and no longer visible.
Second:
I want the btn.click in the function "test" to only be assigned to the button created in the function "test." I've noticed that when you click "Click Me!" it runs the function "ex."
try this one
<script>
function test() {
var btn=document.getElementsByTagName('button')[0];
btn.attributes[0].value="ex()";
btn.innerText="second function";
}
function ex() {
console.log("ex executer");
}
</script>
<button onclick="test()">
click me!
</button>
<button onclick="test()">
Click Me!
</button>
<script>
function test(){
var btn = document.createElement("BUTTON")
var name = document.createTextNode("Button")
btn.appendChild(name);
document.body.appendChild(btn);
btn.onclick = ex;//() remove. btn.onclick is a handler i.e. a function object,
// not the result your ex() returns.
}
function ex(){//add function
this.style.color = 'red'; // makes text of the button red
// **ONLY if button IS clicked**
}
</script>
