I have a form that will be submitted by javascript code triggered in "onsubmit" of the tag. Works fine on all browsers - but not on IE7/IE8.
What can I do?
<form action="/dosomething.htm" method="GET" onsubmit="submitmyform();return false">
[...]
<input type="submit" value="Go">
</form>
I'm going to nitpick this. If you want to handle form submissions, that is what submit is for. If the user hits enter in one of your fields, your onclick handler will be totally avoided. Here is a basic example of doing this in a non-obtrusive way.
<form name="myform">
<input type="submit" />
</form>
<script>
document.myform.onsubmit = function(){
alert('handled');
return false;
}
</script>
This can be made a lot simpler with jQuery, same form...
$("form[name=myform]").bind('submit',function(){
alert('handled');
return false;
});
document.myform or form[name=myform] is just as obtrusive as having an onsubmit attribute in the HTML, except in the opposite direction. What you need is a way of discovering the forms, discovering the validation functions for it (perhaps by naming convention validateMyForm()), and therefore binding automatically and generically. If you really want to be non-obtrusive. It would be reusable too. –
Copp Several ideas proposed here work (because they use different ways to write correct code), but there is a much easier answer
OP wrote :
onsubmit="submitmyform();"
instead of :
onsubmit="return submitmyform();"
That's it.
I don't think your return false is ever reached, as it comes after what's returned from your function.
<form action="/dosomething.htm" method="GET" onsubmit="submitmyform();return false">
Make sure that you return false inside of your 'submitmyform()' function else, if it's not then it could be returning true to you form obsubmit event.
<script type="text/javascript">
<!--
function submitHandler()
{
alert(0);
return false;
}
window.onload=function(){document.getElementById("formid").attachEvent("onsubmit", submitHandler);}
-->
</script>
<form action="/dosomething.htm" method="GET" id="formid">
[...]
<input type="submit" value="Go">
</form>
The attach event method only works only for IE7/8. If you want a reliable cross browser solution you should use addEventListener as an alternative.
Hope it helps
try this. work for me.
onSubmit="javascript:return false"
To cancel an event in legacy IE, you need to set returnValue to false. Simply returning false won't do it. I don't know why Microsoft implemented it in this way.
function validateForm(evt) {
// if form is not valid
if(!condition) {
// if evt has preventDefault
if(evt.preventDefault)
{ event.preventDefault(); }
// if evt has returnValue
else if(evt.returnValue)
{ evt.returnValue = false; }
// fallback
else
{ return false; }
}
}
// assume form is reference to your form
form.attachEvent('onsubmit',validateForm);
The solution for us was to move the javascript event from "onsubmit" of the form to "onclick" of the submit button.
<form action="/dosomething.htm" method="GET">
[...]
<input type="submit" value="Go" onclick="submitmyform();return false">
</form>
onclick event for me. Chrome does, though, but it goes to show that you really can't trust browsers to agree on things unless they're written in the specifications. –
Agueweed I had the same error and when I turned on the console, it never came. So I figured out, it was the console, that wasnt known by the internet explorer as long as it is turned off. Simply add a dummy console to the window with the following code (if there isnt already one):
var myconsole = {log : function(param){}}
window.console = window.console || myconsole;
With this you could get in trouble, if you want to have microsofts javascript console. Then just comment the lines out. But now, the console object is not undefined anymore on the whole site.
<form action="/dosomething.htm" method="GET" onsubmit="return submitmyform(this)">
[...]
<input type="submit" value="Go">
</form>
this works fine... the function must return true or false
In fact, because you write submitmyform();return false only submitmyform is evaluated.
In the case of two commands, you will have to put them between braces like this
{submitmyform();return false;}
so that both are evaluated.
I think that the problem is in return false you need to return it from your 'onsubmit' function
see example.
This form will never be submitted in IE 7/8 as well.
<form action="acknowledgement.html" method="get" onsubmit="verify();">
<input type="submit" name="submit"
VALUE="Submit">
</form>
<script language="javscript">
function verify(){
return false;
}
</script>
Danny.
verify() function returns control to the onsubmit function, so it is the onsubmit function that needs to return false to cancel the default action. –
Agueweed It works - check W3Scools example (taken from ) http://www.w3schools.com/js/js_form_validation.asp
<html>
<head>
<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}
function validate_form(thisform)
{
with (thisform)
{
if (validate_required(email,"Email must be filled out!")==false)
{email.focus();return false;}
}
}
</script>
</head>
<body>
<form action="submit.htm" onsubmit="return validate_form(this)" method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body>
</html>
If you want IE to be standards compliant, you'll have to tell it which standard it's supposed to comply with in a declaration.
Without one it's going to be endless frustration to get it to do what you want. With one, most of the frustration goes away because it starts working as every other browser.
document.forms.userFormRegisterr.onsubmit = function(e){
return false;
};

return false;not to work as it should. We need to see your code to get a better look at what's going on. edit we need to see the code forsubmitmyform(), as it's likely an error is occurring that prevents thereturn false;from being executed. – Agueweed
