I'm trying to get the entire HTML of a page, but it seems that the text stops after </head>. The following code is essentially how I tested this. What am I doing incorrectly here?
<html>
<head>
<script>
document.onload = showHTML();
function showHTML() {
html = document.documentElement.innerHTML;
alert(html);
}
</script>
</head>
<body>
<p> This is absolutely useless text. </p>
</body>
</html>
Okay here is a complete working answer... after checking already posted answer I realized it didn't work for multiple reasons..
First you need to put a function in the onload event. The onload event is written without uppercases.
Also! you need to put the event on the window object as such:
window.onload = showHTML;
Here is a fiddle. Notice on the left that it isn't wrapped inside onload. It's unwrapped in head like your code should be.
You should have something like this:
<html>
<head>
<script>
window.onload = showHTML;
function showHTML() {
var html = document.documentElement.outerHTML;
alert(html);
}
</script>
</head>
<body>
<p> This is absolutely useless text. </p>
</body>
</html>
Take off the parenthesis from document.onLoad = showHTML();
What's happening is showHTML() is being called right away, before the rest of the document is being loaded. Taking off the parenthesis means the function is being set to the onLoad callback.
document.onload no uppercase letter.Try:
<html>
<head>
<script>
document.onload = showHTML;
function showHTML() {
var html = document.documentElement.outerHTML;
alert(html);
}
</script>
</head>
<body>
<p> This is absolutely useless text. </p>
</body>
</html>
When you wrote document.onLoad = showHTML(); you didn't assign the reference to showHTML function to document.onLoad but you assigned the value returned by that function i.e. undefined (because you called it). I also changed innerHTML to outerHTML.
Also document.onload shouldn't be written in camel case.
Writing var html = … isn't essential but it wouldn't run in strict mode. Without it you create a html property on global object window implicitly.
document.onload, not document.onLoadI think this is what you are looking for:
document.onLoad = showHTML();
function showHTML() {
var html = document.documentElement.innerHTML;
alert(html);
}
