I've been researching TypeScript extensively, but I'm still unsure about what type I should set for elements X and Y. Can someone help me understand how I can convert this code to TS? Thank you in advance for your assistance.
const x = document.getElementById("password-input");
const y = document.getElementById("img");
function showPass() {
if (x.type === "password") {
x.type = "text";
y.src = "png"
} else {
x.type = "password";
y.src = "png"
}
}
By using the ! symbol, you are indicating that the element will not be null (assuming it exists in your HTML document). Additionally, as HTMLInputElement specifies the type of element.
For further information on this topic, you can refer to this informative article.
const x = document.getElementById("password-input")! as HTMLInputElement;
const y = document.getElementById("img")! as HTMLInputElement;
function showPass() {
if (x.type === "password") {
x.type = "text";
y.src = "png";
} else {
x.type = "password";
y.src = "png";
}
}
In order to use TypeScript in the browser, you must first compile it. For your specific situation, it's important to define the HTMLElement for both x and y. This is crucial because properties like x.type, y.src, src, and type are not inherently part of the HTMLElement object
const x: HTMLInputElement = document.getElementById("password-input");
const y: HTMLImageElement = document.getElementById("img");
function showPass() {
if (x.type === "password") {
x.type = "text";
y.src = "png";
} else {
x.type = "password";
y.src = "png";
}
}
