(I've changed the input tag with a button tag.) This probably is a stupid question, but here goes. I have an input button like this:
<button type="submit"
id="choice"
value="Escolher"
onClick="javascript:makeChanges()">
It works well in IE, but in firefox it just doesn't do anything; there are no errors, no behavior what so ever.
My "makeChanges()" function does the following:
var selObj = document.getElementById('opiniao');
var selIndex = selObj.selectedIndex;
var str = selObj.options[selIndex].text +'&random='+(new Date()).getTime();
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
开发者_Go百科 xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","writeSettings2.php?text="+str,true);
xmlhttp.send(null);
history.go(0);
}
If i put for isntance an alert on the call like:
<button type="submit"
id="choice"
value="Escolher"
onClick="alert('Hello')">
The button works, but it dosent when i try to call the javascript function.
<input type="submit" /> is for submitting form data. Without <form> firefox doesn't know where or how the form should be submitted, so it doesn't submit.
If you want to use a button without a form, you can use the <button> tag.
try:
<input type="button" id="choice" value="Escolher" onClick="makeChanges()" />
what is your javascript? maybe there is a mistake?
Can you add some context about your code around this input element? Is it in a form (doesn't sound like it)? The "submit" input type needs to be in a form...can you just change it to a button input element instead?
<input type="button" id="choice" value="Escolher" onClick="javascript:makeChanges()">
The input is of type submit. Which indicates to submit a form. Without a form, Firefox doesnt know what to submit.
I just tried your code and it worked ok in Firefox 3. On the following HTML. Check if your function is defined. Or maybe it is your Firefox version?
<html>
<head>
<script type="text/javascript">
function makeChanges(){
alert('hi');
}
</script>
</head>
<body>
<input type="submit"
id="choice"
value="Escolher"
onClick="javascript:makeChanges()">
</body>
</html>
indeed this doesnt work on firefox (but works on IE, Chrome):
input type="button" value="Show Results" onClick="javascript:show()"
the solution is just put the javascript code inside the onClick, for instance:
input type="button" value="Show Results" onclick="document.getElementById('dsp').value=1;sertificatesStatsForm.submit();"
If you have the type as "submit", browsers will attempt to post data to the enclosing <form> element's "action" attribute. You can disable this by adding "return false;" to your onclick handler. As others have said, "button" is the more appropriate type to use in this case. The below bare-bones example works for me:
<input type="button" onClick="javascript:alert('hello');" />
Do you perhaps have NoScript installed in Firefox? Normally, file:// is not allowed to execute JavaScript code.
