As a beginner in JS, I'm curious about how to display the results of my code. When I try to use this small snippet of test code, the browser shows a blank page:
if ( 11 > 10 )
{
console.log("You made it!")
}
else
{
console.log("You have just died!")
}
I would like to know how to showcase my code in the same way as this website does:
If you're looking for a quick and easy solution, try this approach:
document.write( "text" ) //de ...or:
document.writeln( "text" )
For a more sophisticated method, consider creating a DOM element to write your text into. Here's an example:
Start by adding an element like
<div id="console"></div>function debug_output( text ) {
document.getElementById( "#console" )
.insertAdjacentHTML(
'beforeend',
'<span class="debug_output">' + text + '</span><br/>'
);
//de thanks to @cookiemonster for the .appendChild fix
}
If your aim is to display plain text in the browser, I'll show you how to bypass using console.log and instead write directly to the browser.
The second code snippet provided allows you to achieve that, giving you the flexibility to style or position your debug output as needed.
Here's the full solution implementing the "more elegant" way mentioned above:
if ( 11 > 10 ) {
debug_output("You made it!")
} else {
debug_output("You have just died!")
}
If you're looking to display some values on the console, you'll need to utilize the developer tools that come with your preferred browser.
Take a look at this resource for more information: https://developers.google.com/chrome-developer-tools/
To showcase content directly within an HTML document, you'll have to insert a DOM element into your code.
var container = document.getElementById('container');
if ( 11 > 10 )
{
container.innerHTML ="You made it!";
}
else
{
container.innerHTML = "You have just died!";
}
Here's an example link to see the code in action: http://jsfiddle.net/azTX4/3/
It all depends on your intended action... one option is to notify the user
alert(MESSAGE);
Alternatively, you could update the content of a DIV:
document.getElementById('someDiv').innerHTML = MESSAGE;

If you're able to encapsulate your code within a specific function, you have the option to insert your JavaScript code within the pre tag and ultimately into the body section, similar to the example below.
var myJavaScript = function () {
if ( 11 > 10 ) {
console.log("Congratulations!")
}
else {
console.log("Game over!")
}
}
document.write('<pre>' + myJavaScript + '</pre>');
