I'm trying to call a function with an onClick command, but I get the error "Can't find variable" in the Safari console and no action is taken. I can't see any errors, but I must be missing something that is causing this to fail.
The link
<a href="JavaScript:void(0);" onclick="controlWallMonitor('layout','Playback');">Show playback layout</a>
The Javascript
<script type="text/javascript">
$(document).ready(function() {
function controlWallMonitor(variable, option) {
var WallMonitor = "10.0.50.163:9000";
$.ajax({
url: 'changelayout.php?target=' + WallMonitor + '&variable=' + variable + '&option=' + option,
});
return false;
};
});
I'm sure it'll end up being incredibly obvious, but I have been googling and trying things for about 2 hours now and can't for the life of me see the problem.
Cheers.
addEventListener can add multiple events to a particular element. onclick can add only a single event to an element.
The onclick attribute is an event attribute that is supported by all browsers. It appears when the user clicks on a button element. If you want to make a button onclick, you need to add the onclick event attribute to the <button> element.
We can create an HTML button element and use the native onclick event. The value of this event will be a callback function activateLasers() . So when the button is clicked, activateLasers() is also called and adds an alert to our screen.
There are a number of DOM (Document Object Model) events that you can listen for in JavaScript, but onclick and onload are among the most common.
Remove the $(document).ready call from around the function, all you have to do is put it after the jQuery script inclusion.
EDIT: Also, instead of using onclick, use a jQuery event handler:
HTML:
<a href="JavaScript:void(0);" class="playback">Show playback layout</a>
JS:
$(document).ready(function(){
$("a.playback").click(function(){ controlWallMonitor('layout', 'Playback'); });
});
