How do I target message using JavaScript here to write to the tag? Here is my HTML code:
<h1 message = "this is the title of the page"></h1>
The message should only show in certain circumstances. Just wondering how I would use JavaScript to grab that element and inject its contents into the h1 tag when needed?
You could do it as below. Feel free to adapt it to your use case, as for now, it will write into the <h1> as soon as the script is loaded and gets executed.
const h1 = document.querySelector("h1");
h1.textContent = h1.getAttribute("message");<h1 message = "this is the title of the page"></h1>getAttribute method is used to get the value of any attribute in html tag.
Syntax of using getAttribute
element.getAttribute (attributename);
const target = document.querySelector("h1");
// Original attribute
console.log(target.getAttribute("message"))<h1 message="I am message in h1 tag"></h1>setAttribute method is used to set the value of any attribute in html tag.
Syntax of using setAttribute
element.setAttribute(attributename, attributevalue);
const target = document.querySelector("h1");
// Original attribute
console.log(target.getAttribute("message"))
// changed attribute
target.setAttribute("message","message attribute changed")
console.log(target.getAttribute("message"))<h1 message = "this is the title of the page"></h1>https://stackoverflow.com/questions/72569107/use-javascript-to-write-text-into-html-interface#
