<html>
<head>
</head>
<body>
<script>
var myFunction = function(){
return "hello world";
}
</script>
myFunction();
</body>
</html>
I just finished the code academy course on javascript but it didn't taught me how to code javascript inside html. I need to display hello world inside the html's tag using the function is this possible? my friend told me I need jquery just to do this.
You have to specifically tell the webpage to execute your function when it's loaded.
Instead of returning the string I believe you'd like to write it in the body of the webpage.
This is a simple way to do so :
<html>
<head>
<script>
var myFunction = function(){
document.body.innerHTML = "hello world";
}
</script>
</head>
<body onload='myFunction();'>
</body>
</html>
document.write.
<html>
<head>
</head>
<body>
<Script>
function myFunction(){
document.write("hello");
}
</script>
<Script>
myFunction();
</Script>
</body>
</html>
This was asked already How to call a javascript function within an HTML body
I just replace the
tag with document.write
document.write. It's unpredictable.Try this
<html>
<head>
</head>
<body onload='myFunction()'>
<script type="text/javascript">
var myFunction = function(){
return "hello world";
}
</script>
</body>
</html>
<script>tagdocument.writeto write inside HTML in place of return
