Let's say I have a variable called x in javascript. How can I set the value of a text input (HTML) to that variable? For example:
The value of the input will now be Swag
<input type="text" value="Swag" />
But if I want the value to be a javascript variable? How do I do? Something like this? (I am just guessing, trying to make my point clear)
<input type="text" value="variable.x" />

The simple assignment operator ( = ) is used to assign a value to a variable. The assignment operation evaluates to the assigned value. Chaining the assignment operator is possible in order to assign a single value to multiple variables.
We can get the value of the text input field using various methods in JavaScript. There is a text value property that can set and return the value of the value attribute of a text field. Also, we can use the jquery val() method inside the script to get or set the value of the text input field.
The Input Text defaultValue Property in HTML DOM is used to set or return the default value of the Text Field. This property is used to reflect the HTML value attribute.
To change the type of input it is (button to text, for example), use: myButton. type = "text"; //changes the input type from 'button' to 'text'. Another way to change or create an attribute is to use a method like element.
This is a better solution and will probably avoid confusion for newbies...
<!DOCTYPE html>
<html>
<body>
<h1>Input and Display Message</h1>
<p>Enter a message</p>
<input type="text" id="msg" ><br>
<button onclick="displayMessage()">Click me</button>
<p id="showinputhere"></p>
<script>
function displayMessage(){
let themsg = document.getElementById("msg").value;
if (themsg){
document.getElementById("showinputhere").innerHTML = themsg;
}
else{
document.getElementById("showinputhere").innerHTML = "No message set";
}
}
</script>
</body>
</html>
You can set it in your javascript code like:
<input id="myInput" type="text" value="Swag" />
<script>
var test = "test";
document.getElementById("myInput").value = test;
</script>
