I have the onclick event: onclick="javascript:_stats_content('my_bets');" which works fine.
This loads new content into a div.
However I want to set a default piece of content to load when the page loads. I have attempted to do this with the code below, but it is not working:
<body onload="myFunction()">
<script>
function myFunction() {
_stats_content('my_bets'); // have also tried with 'javascript:' infront
}
</script>
Can anyone provide any solutions?
Thanks.
EDIT:
Upon reading comments, I have added type="text/javascript".
I also replaced with an alert() and it fails to show. I should note that I am using AngularJS to display the page so this might interfere. However the first onclick example works fine on the page, so I don't understand how onload would be any different.
EDIT2: This is an extract of code from the top of the page:
<head>
<script type="text/javascript">
function myFunction() {
alert("Hello! I am an alert box!!");
}
</script>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="content/ext/msgbox/Scripts/jquery.msgBox.js"></script>
<link rel="stylesheet" type="text/css" href="content/ext/msgbox/Styles/msgBoxLight.css">
<script type="text/javascript" src="content/ext/qtip/jquery.qtip.min.js"></script>
<link rel="stylesheet" type="text/css" href="content/ext/qtip/jquery.qtip.min.css">
<script type="text/javascript" src="js/colors.js"></script>
<?php include './js/includer.php'; ?>
</head>
<body onload="myFunction()">
I have replaced with an alert to make it easier to troubleshoot, although the alert is still not showing. I think it's just an AngularJS related issue, guess I'll just have to figure this out.
Whilst I wasn't able to get this exact method to work, the reason for which I still have no idea. I imagine it's AngularJS interfering.
I used:
<img src="87.jpg" onload="javascript:_stats_content('my_bets');" width="0" height="0">
Just before the </body> tag and that worked.

this is a very odd problem indeed and I hope it's simple. I cannot get a simple select and append to work in my html document, but it works when I'm in the chrome browser console.
<html>
<head>
<script src="https://code.jquery.com/jquery-1.12.3.min.js" integrity="sha256-aaODHAgvwQW1bFOGXMeX+pC4PZIPsvn2h1sArYOhgXQ=" crossorigin="anonymous"></script>
<script src="/js/script.js"></script>
<script>
$('[data-js="works"]').append("hello");
</script>
</head>
<body>
<div data-js="works"></div>
test
</body>
</html>
When I put that line of script in the console, hello appears above test. When I just open the page, test is there alone. I was running a script from this page earlier and when I tried to select an element it didn't work. I then went to inline script to see if it would even work there, no. I've seen if it works from inline script without the imported script, also no. Console has no bug information. I can print from that inline script to my console if I want, but this code still isn't running properly.
Doesn't work with my local httpserver and doesn't work just as a locally opened file.
This is because the script is executed before the page is loaded so the target div does not exist yet.
The solution is to wait for the page to be fully loaded before doing something.
The $ function can be used for this. Give it a callback and it will be executed once the page is loaded.
You can also use window.addEventListener("load", callback); that doesn't need jQuery.
<html>
<head>
<script src="https://code.jquery.com/jquery-1.12.3.min.js" integrity="sha256-aaODHAgvwQW1bFOGXMeX+pC4PZIPsvn2h1sArYOhgXQ=" crossorigin="anonymous"></script>
<script>
$(function(){
$('[data-js=works]').append("hello");
});
</script>
</head>
<body>
<div data-js="works"></div>
test
</body>
</html>
Another solution can be to insert your script at the end of the page. It is not as neat though in my opinion.
<html>
<head>
<script src="https://code.jquery.com/jquery-1.12.3.min.js" integrity="sha256-aaODHAgvwQW1bFOGXMeX+pC4PZIPsvn2h1sArYOhgXQ=" crossorigin="anonymous"></script>
</head>
<body>
<div data-js="works"></div>
test
<script>
$('[data-js=works]').append("hello");
</script>
</body>
</html>
Try the following, hope it will solve your problem
(function($) { // This will solve namespace problem (if any)
// Write your JQuery code here
})(jQuery);
Either you put the .js file at the end of the body or put your JS code between $(document).ready(function(){ //code inside })
I'm new to HTML, JavaScipt and everything related to programming, and I'm trying to create a simple page.
Now, I'm stuck with the following problem: I want to change the date of my main.html file, but the main.js is not working. I've already change the <script> position to inside the <body>, after the </span> and even after the </body>, without success. If the content of the main.js is within the HTML it works fine, but as a external file it doesn't.
Here is my main.html:
<!DOCTYPE html>
<html>
<head>
<link href="main.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src="main.js"></script>
<title>Page 1</title>
</head>
<body>
<p>WRF<br>
<span id="data">18/09/1987</span></p>
</body>
</html>
My main.js is just:
document.getElementById("data").innerHTML = "JUBA";
I've looked through the internet and through this forum, but all answers that I've found did not worked.
The files are on the same directory and the main.css works fine.
Thank you in advance.
At time you call main.js element #data was not created in DOM tree. You can fix this by putting the link to your Javascript file right before closing the body like this:
<script type="text/javascript" src="main.js"></script>
</body>
Document Object Model (DOM) is not "READY".
Try use onload event, inside main.js:
window.onload = function() {
document.getElementById("data").innerHTML = "JUBA";
};
If needs more "fast" than onload, use jquery with $(document).ready:
html:
<link href="main.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="main.js"></script>
main.js:
$(document).ready(function() {
$("#data").html("JUBA");
});
window.onload vs $(document).ready()
Answer by #Guffa:
The ready event occurs after the HTML document has been loaded, while the onload event occurs later, when all content (e.g. images) also has been loaded.
The onload event is a standard event in the DOM, while the ready event is specific to jQuery. The purpose of the ready event is that it should occur as early as possible after the document has loaded, so that code that adds functionality to the elements in the page doesn't have to wait for all content to load.
The element is not yet accessible when you run the script.
Either you can put the script at the end of the page or delay the execution.
You could put the JavaScript in the <body> tag after the rest of the page. When the browser loads it, the <span> will already be there to be edited.
As per your code the script will be called first then page will be loaded, therefore when the script is running there will not be any element having id data because yet page have to be loaded. There are many ways to achieve what you need.
1. Add a script tag before or after end of body like
or
<script type="text/javascript" src="main.js"></script>
</body>
Write .js file above before body i.e. in head tag and write the whole javascript code in onload method.
window.onload=function(){
document.getElementById("data").innerHTML = "JUBA";
};
window.onload=function(){
document.getElementById("data").innerHTML = "JUBA";
};
<p>WRF<br>
<span id="data">18/09/1987</span></p>
I had a problem with some functionality working in all browsers except for Safari, and I have reduced the problem down to this.
In my page I have the following script declarations at the end of my body element:
<script type="text/javascript" src="../../Scripts/jquery-1.5.1.min.js"></script>
<script type="text/javascript" src="../../Scripts/jquery-ui-1.8.11.min.js"></script>
<script type="text/javascript" src="../../Scripts/jquery.ui.autocomplete.html.js"></script>
<script type="text/javascript" src="../../Scripts/jquery.validate.min.js"></script>
<script type="text/javascript" src="../../Scripts/jquery.textchange.min.js"></script>
<script type="text/javascript" src="../../Scripts/jquery.reveal.js"></script>
<script type="text/javascript" src="../../Scripts/mainScript.js"></script>
Then inside the mainScript.js file, I have put the following code:
$(function () {
alert("found");
});
In all other browsers, it displays a message box, but in Safari it does nothing.
Safari's javascript debugger lists the script, and can see the contents, but for some reason it's not included.
I found this problem since I tried to call a function in mainScript.js from an inline script inside the html page (the inline script was defined below the mainScript.js definition), and the Safari debugger complained that the function was not found anywhere.
What have I done wrong here, and why does not Safari include this script. All the jquery scripts are included and are working fine.
Your code seems good.
I tried with this code
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<h1>Test</h1>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
alert("Test");
});
</script>
</body>
</html>
and it works fine (Safari 5.0.5 7533.21.1 on Windows 7).
A couple of questions:
Have you tried calling your function manually from the Error Console? Does it work?
If you place a simple alert("Test."); outside of the document ready function, is it displayed?
If you call jQuery's function from the Error Console, what do you get? Do they work?
The problem was found elsewhere in mainScript.js.
{ class: 'someclass' } was sent as parameter to some method, and class is a reserved word.
This should probably have given errors in other browsers as well, but they gladly ignored it and kept on going.
The fix was simply to change it to { 'class': 'someclass' }
I'm writing text to a page using document.write for a Chrome extension, but the associated custom CSS isn't applied:
<!DOCTYPE html>
<html>
<head>
<title>TITLE GOES HERE</title>
<link rel="stylesheet" href="css/popup.css" type="text/css" />
</head>
<body>
<script type="text/javascript">
...
function showFolder(folder) {
console.debug('FOLDER: '+folder.title);
document.write('<p>'+folder.title+'<br></p>');
}
</script>
</body>
</html>
The CSS is simple, just for debugging:
p {
color: red;
}
I can get it to work if I put the stylesheet link inside the function showFolder, but that can't be the proper way to do it. I'm learning jscript/CSS on the fly, so the answer is probably something remedial. Is the problem in the jscript, the CSS or both?
Use innerHTML.
<div id="towrite"></div>
then you can write in it like this:
div=document.getElementById('towrite');
div.innerHTML = '<p>'+folder.title+'<br></p>';
If you run your document.write() before the page finishes loading (perhaps calling your showFolder call directly from a script on the page), then the text will be written into the document as you might expect.
However, if you call document.write after the page loads, as in an event handler, you will be writing an entirely new page. This is usually not what you want.
Instead, follow Zoltan's advice and set the innerHTML property of an empty div.
I'm not javascript expert... I mainly use jQuery.. but try this, kind of makes sense:
<!DOCTYPE html>
TITLE GOES HERE
<script type="text/javascript">
...
function showFolder(folder) {
console.debug('FOLDER: '+folder.title);
document.write('<p>'+folder.title+'<br></p>');
}
</script>
<link rel="stylesheet" href="css/popup.css" type="text/css" />
EDIT:
So the above didn't work, but I just thought about another solution. When are you actually calling the function? Try to put it in <body onLoad="functionnamehere()">
No idea if that works, but give it a try.
I am trying out jqueryUI, but firebug catches the following error on this script:
$(function(){$("#date").datepicker()});
The firebug error reads:
$("#date").datepicker is not a function
On my html, the "date" id looks like this:
<input type="text" name="date" id="date" >
NB: I have used the correct JqueryUI css/js scripts on the section
Nothing is executing...
jQuery documentation says you can call the datepicker by this command:
$("#datepicker").datepicker();
If you click the 'view source' button on the documentation page you can see that they've wrapped it into the ready function:
$(document).ready(function(){
$("#datepicker").datepicker();
});
EDIT: It should work with INPUT (thanks for pointing this out Steerpike). This is the test I've written and it works, try it yourself:
<html>
<head>
<link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script>
<script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.datepicker.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#datepicker").datepicker();
});
</script>
</head>
<body>
<input type="text" id="datepicker" value="this is a test">
</body>
</html>
You're almost certainly not loading the datepicker plugin properly. Please supply us the code you're using to include the javascript files.
If you keep having problems, load the jquery and the UI from the google api.
<link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("jquery", "1.3.2");
google.load("jqueryui", "1.7.0");
</script>
for me it was just case of making sure the jquery ui was the last one in the list of all the js includes.
$(document).ready(function(){
// Your code here
});
make sure your function is inside the .ready main function.
It's an old post but I got here when looking for a solution so people still read it ;) I have or rather had the same problem. In my case it turned out that I was attaching js in html in wrong way (notice in what way I was ending script tag)
WRONG: <script type="text/javascript" src="/fbo/js/jquery-ui-1.8.14.custom.min.js"/>
GOOD: <script type="text/javascript" src="/fbo/js/jquery-ui-1.8.14.custom.min.js"></script>
When I was doing it in the wrong way I had the same error.
You are probably loading prototype.js or another library that uses $ as an alias.
Try to replace $ with jQuery.
