function myFunction() {
location.replace("https://www.w3schools.com")
}
in the script tag
<button onclick='myFunction()'>Submit</button>
in the html
Any idea why this very basic command doesn't work?
check this example:
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_redirect_webpage
If your button is inside the form then need to specify as type of button
<form>
<button onclick="myFunction()" type="button">Replace document</button>
</form
I tested your code and it works fine..
Try clearing your cache inspect and right click on reload choose clear cache.
Did u link your script file ?
<script src="script.js"></script>

Im actually having a problem with html5 button in visualforce pages. I have a requirement where when i click on a button, it should redirect to a certain page (user do not want link). For some reason which i don't know, the function i'm executing do not work with HTML5 button (in fact the page only refresh but do not redirect) but when i use input of type button, the function is executed as expected.
I want to use the html5 button as there are some specific css already defined for button in the plugin im using. Find below codes for my button and javascript function :
<button class="butt" onclick="newContact()" >Nouveau</button>
<script type="text/javascript">
function newContact(){
window.location = "/apex/VFP01_NewContact";
}
</script>
What did I do wrong here, and what is the limitation of html5 button ?
Got to know the answer. In visualforce page, the html5 button execute a submit of my form. A way to prevent this, was to specify the attribute type="button".
You really have two options.
You could consider wrapping a element with an anchor tag that points to the URL that you want to target as seen below :
<!-- Target the "YourAction" action in your "YourController" controller -->
<a href='#Url.Action("YourAction","YourController")'>
<input type="Button" id="mybutton" name="url button" value="Next" />
</a>
or you could handle this purely through Javascript and perform your navigation that way :
<!-- The onclick event will trigger a Javascript call to navigate -->
<input type="Button" id="mybutton" name="url button" value="Next" onclick="window.location.href='#Url.Action("YourAction","YourController")';" />
I'm working with html and javascript. My problems is, in one webpage a show a plot and a few button. When the user press any of this button I need show 3 or 4 options but in the same page without switching pages.
Below is my code
<form action="MyPage">
<button type="submit" value="More Options">
</form>
redirect to an other page.What I can do?
First of all, get rid of type="submit". That's what's causing the page to do stuff you don't want. The second thing is to add an onclick handler. It should return false to avoid behavior like "submit". The variable 'this' will pass the button to your function, which you might need in that code. Then fill in the body of addMoreStuff() with your code to, well, add more stuff!
<form action="MyPage">
<button onclick="addMoreStuff(this); return false; ">More Options</button>
</form>
<script type="text/javascript">
function addMoreStuff(button) {
/* your code here */
}
</script>
Drop the form (use the button alone), and look into jQuery. It's extremely easy to use, and it'll help you quickly build code your application.
HTML
<button type="submit" value="More Options" id="more">
JavaScript (jQuery)
// run "add_options" when someone clicks on the button
jQuery('button#more').on('click', add_options)
function add_options() {
//code here to add more options
}
I have a button example below
<button id="startrunning">go</button>
There is no form or anything I'm using on the same page java script to detect it's click. It will work like I want it to when I click it. I want to see when the page is loaded it will automatically submit it's self is there a way?
Thank you
jsFiddle: http://jsfiddle.net/QEu84/10/
<script type="text/javascript">
function submit()
{
document.getElementById("startrunning").click(); // Simulates button click
document.submitForm.submit(); // Submits the form without the button
}
</script>
<body onload="submit()">
<form id="submitForm">
<button id="startrunning">go</button>
</form>
</body>
You can automatically click it when the page loads, using the code below, but you need a form to submit something (you submit a form, not a button)
<body onLoad="document.getElementById('startrunning').click();">
I want to execute a command by the click of a button, and not when the page loads.
function hey() {
alert('bla');
}
Do I add something to the code above or to the button?
<input type="button" value="Click Me" onclick="hey()" />
Have you taken the time to type in your question into the magical Google box yet? Surely you'll see something like this:
<input type="button" value="Click me, now" onclick="hey()" />
Say you have the function that alerts a window to the user.
<script type="text/javascript">
function showMe() {
alert('You clicked on the button');
}
</script>
<button onclick="showMe()">Button</button>
This will make sure that the function is only called when the button is clicked upon and not when the page is loaded.
Okay, so you have a code that should work for alerting something on the click of a button. But you state that the code is running on page load. You have to check you code, looking for:
An onload attribute on the body tag, something like <body onload="hey()">
A call to hey somewhere else on your js code. Look for hey().
Maybe a reference to the button followed by a call to .click()
There is something else on your code causing the function to be called, you'll have to scan your code to find out what it is.
I have written this code for Firefox:
<html><head><title>No</title>
<script type="text/javascript" src="jquery-1.4.2.js"></script>
</head>
<body>
<form action="javascript:void(alert('Yes'));">
<input type="submit" value="Submit">
</form>
<script>$($('form').submit())</script></body></html>
It correctly displays the alert box.
However, when i run this inside an iframe, with this code:
<html><body><iframe src="click.php"></iframe></body></html>
i don't get the alert box, not even if i click the submit button myself.
What is going on exactly? The same code works in Chromium
Well, don't do that then!
It doesn't make any sense to submit a form to a javascript: URL. Use a submit event handler to pick up the form submission and execute script, eg using jQuery:
$('#someform').submit(function() {
alert('Yes');
return false;
});
A good rule of thumb about when to use javascript: URLs is: never.
It looks like it's a problem with FF4 so I'll discuss it on their bugzilla if it's really their fault. I have modified the source so I'm not even sure it is a bug...
