onCLick() problem
I have been reading to stay away from JavaScript for a lot of things, however I was messing around with it and it doesnt seem to work (unless I am blind and have missed something)
<SCRIPT LANGUAGE="text/javascript">
function testResults() {
System.out.println("Got into function");
}
</SCRIPT>
And this is my body:
<form action="" method="GET">
<input type="button" value="Save" name="saveType" style="margin:10px;" onClick="testResults()"/>
</form>
From what I have seen of 开发者_Go百科javascipt this should be fine... Any suggestions?
Use console.log
instead of system.out.println
...
Javascript is not Java!
A few pointers:
- it's
type="text/javascript"
- why capital letters?
System.out.println
is Java
Stay away from JavaScript? Currently it's almost like the opposite, but as almost always it depends on what you have to do :)
to get it work use this instead:
Look here - jsfiddle
<form action="" method="GET">
<input type="button" value="Save" name="saveType" style="margin:10px;" onClick="testResults()"/>
</form>
<script type="text/javascript">
function testResults() {
alert("Got into function");
}
</script>
it is type="text/javascript
and not language="text/language"
also in javascript you have to use alert()
.
Javascript doesn't have a standard output like that. You have a few options:
- If you have a debugging console running, you can use
console.log("log a message")
- You can output debug information to a HTML element:
document.getElementById("myelement").innerHTML = "message here";
There are loads more options - I'd suggest learning Javascript properly. It's not that much like Java.
- Java =>
System.out.println
orSystem.out.print
- Javascript =>
console.log
:)
