"如何查看 console.log() 的输出？"

Question

I am using this code:

<script type = "text/javascript">
 console.log("hello world");
</script>

How can I see the output of console.log() ?

I searched on Google but did not find a solution.

Answer 1

You can open the error console, depending on your browser. (Ctrl+Shift+J in Firefox, or F12 in Chrome, for example). Most browsers have the console hidden in their developer tools.

Answer 2

The console.log(); statement prints anything in the browser console.

Look for Developer Tools or Simply Tools menu in all major browsers.

If you are using Google Chrome the press Cntrl+shift+j to see console.

In Firefox, press Ctrl+Shift+I and click on Console to view the console on Firefox.

Answer 3

You need to view the result in the console. Open the console.

Also, you have a problem with your code.

<script type = "text/javascript">
console.log("hello world");
</script>

Is not valid. Remove the spaces in the script tag, like this:

<script type="text/javascript">
console.log("hello world");
</script>

Answer 10

<script>
function imadumbperson() {
var me document.getelementbyid('demo');
console.log(me);
}
<script>

if only console can have id and a new variable called selfMessage(); so we can do the same:

<script>
function imadumbperson() {
var me document.getelementbyid('demo');
console.log(me); { id='console' }
var me2 document.getelementbyid('console');
selfmessage(me2)
}
<script>

so if this happend then the console will keep it and then the message will come to us. the best way

Answer 11

due to mathimathics, the console.log(say);<\/code> is not detectable. but it can say what the input it was to the user

<input id='demo'/>
<script>
var myDomain = document.getElementById("demo").innerHTML = 'hello,' + myDomain;
</script>
