In a following code I want to access user data written in a form each time user presses an enter key after typing some text data inside an input field in chat-form. Do you have any idea how can I access the following text-data using TypeScript? I have already tried with jQuery but none of the tested code seems to work. I am new to web-dev but very eager to learn new things.
<div id="chat-container">
<div id="search-container">
<input type="text" placeholder="search" />
</div>
<div id="conversation-list">
</div>
<div id="new-message-container">
<a href="#" id="test">+</a>
</div>
<div id="chat-title">
</div>
<div id="chat-message-title">
</div>
<div id="chat-form">
<input id="chat-form" type="text" placeholder="Type a message!" />
</div>
</div>

first, you should use a semantic HTML by using form tag instead of div so u can use enter key to handle the submit action. second, it is not an appropriate way to duplicate an id for two different elements because id is a unique identifier for the element. finally here is a simple form and it might be helpful. HTML:
<form id="my-form">
<input type="text" id="my-input" />
<button type="submit" id="submit-btn">send</button>
</form>
JS:
const formEl = document.getElementById("my-form") as HTMLFormElement;
const inputEl = formEl.querySelector("my-input") as HTMLInputElement;
const submitBtnEl = formEl.querySelector("submit-btn") as HTMLButtonElement;
formEl.addEventListener("submit", e => {
e.preventDefault();
// do what you want
});
inputEl.addEventListener("change", (e:Event|any) => {
console.log(e.target.value)
// do what you want
})
Before the answer: you have duplicated id="chat-form"
<div id="chat-form">
<input id="chat-form"type="text" placeholder="Type a message!"/>
</div>
Example
// select element
const elInput: HTMLInputElement = document.querySelector(`#chat-form-input`)
// add onkeypress listener
document.onkeypress = function (e: any) {
// use e.keyCode
if (e.key === 'Enter') {
// code for enter
console.log(elInput)
console.log(elInput.value)
}
}
<body>
<div id="chat-container">
<div id="search-container">
<input type="text" placeholder="search"/>
</div>
<div id="conversation-list">
</div>
<div id="new-message-container">
<a href="#" id="test">+</a>
</div>
<div id="chat-title">
</div>
<div id="chat-message-title">
</div>
<div id="chat-form-container">
<input id="chat-form-input" type="text" placeholder="Type a message!"/>
</div>
</div>
