I've got a sample script as below. I wanna see if local.js or online/latest.js failed to load. Is it possible?
<html>
<title>My JQuery Test</title>
<head>
<!--<script type="text/javascript" src="jquery/jquery.local.js"></script>-->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("#Buttons-theTestAlert").click(function () {
alert("`Test Alert` clicked");
});
});
</script>
</head>
<body>
<button id="Buttons-theTestAlert">Test Alert</button>
</body>
</html>
You can test
if (myFunction) myFunction()
else alert('not loaded (yet)')

after to make some research I took the measures to guarantee that the JS will be loaded before trying to run it but... it won't work!
This works:
<!DOCTYPE html>
<head>
<meta name="viewport" content="initial-scale=1" charset="utf-8">
</head>
<html>
<body>
<script type="text/javascript">
function initialize() {
console.log('foo')
}
window.onload = function() {
initialize();
};
</script>
</body>
</html>
But this doesn't:
<!DOCTYPE html>
<head>
<meta name="viewport" content="initial-scale=1" charset="utf-8">
</head>
<html>
<body>
<script type="text/javascript" src="test.js">
<script type="text/javascript">
window.onload = function() {
initialize();
};
</script>
</body>
</html>
test.js:
function initialize() {
console.log('foo')
}
I don't get any error. It just doesn't work. What am I doing wrong?
Thanks!
You need a closing script tag for the tag that is calling the external js file.
<script type="text/javascript" src="test.js"></script>
Does anyone know why my jquery won't run? I've tried running on button click or page load but it isn't working. Thanks
<head>
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</head>
<body>
<iframe style="width:100%;height:700px;" id="frame" src="bing.com">
<script>
$(document).ready(function() {
alert("working");
});
</script>
</body>
You need to close your iframe tag and put in the complete url like this:
<head>
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</head>
<body>
<iframe style="width:100%;height:700px;" id="frame" src="http://bing.com"></iframe>
<script>
$(document).ready(function() {
alert("working");
});
</script>
</body>
I am just learning jQuery and the page with the following code does not load. Any help will be greatly appreciated.
<!DOCTYPE html>
<html>
<head>
<title>First jQuery-Enabled Page</title>
<script type="text/javascript" src="jquery-1.11.0.js"></script>
<script type="text/javascript">
$("document").ready(function() {
alert("The page just loaded!");
});
</script>
</head>
<body>
</body>
</html>
$(document).ready(function() {
alert("The page just loaded!");
});
remove quotes from around document in jquery selector.
The below code is intended to return json object from arraylist but it is not showing alert.
there is no js error...
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="json.js" />
<script type="text/javascript" src="json2.js" />
<script type="text/javascript">
var my_info= {};
my_info["john"]="1a";
my_info["joseph"]="2b";
my_info["helen"]="3c";
var val = JSON.stringify(my_info);
alert(val);
</script>
</head>
<body>
</body>
</html>
Script tags don't allow self-closing (<script ... />). You have to use <script src="..."></script> instead.
See for more information this question.
Your code becomes:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="json.js"></script> <!-- Here -->
<script type="text/javascript" src="json2.js"></script> <!-- And here -->
<script type="text/javascript">
var my_info= {};
my_info["john"]="1a";
my_info["joseph"]="2b";
my_info["helen"]="3c";
var val = JSON.stringify(my_info);
alert(val);
</script>
</head>
<body>
</body>
</html>
JSFIDDLE (ignore the warnings)
I'm trying to do a very basic jquery tutorial but I'm not able to get it to work.
I'm calling the jquery library from google and then I try to create a script inside html.
If I do the same in a .js file I wouldn't have any problem.
What am I missing here?
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
</head>
<body>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js">
$(document).ready(function() {
$("a").click(function() {
alert("Hello world!");
});
});
</script>
Link
</body>
</html>
You need to split this up:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js">
$(document).ready(function() {
$("a").click(function() {
alert("Hello world!");
});
});
</script>
...into two script elements:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function() {
alert("Hello world!");
});
});
</script>
In the snippet you gave, the code within the <script> element won't be evaluated because the browser is only evaluating the contents from the src attribute and ignoring everything else.
Move your scripts into the head element like this:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("a").click(function () {
alert("Hello world!");
});
});
</script>
</head>
<body>
Link
</body>
</html>
