How do I get Google Chrome (9.0.597.98 on Windows 7 64-bit) to fire a form's onchange? If you play around with the following example, nothing gets consoled out. It's working fine in Firefox 3.6.13.
<form onchange="console.info('form changed')">
<select>
<option>uno</option>
<option>dos</option>
</select>
<input type="radio" name="videoDevice" value="tres" checked="checked" />
<input type="radio" name="videoDevice" value="cuatro" checked="checked" />
</form>
Binding the change
event via JS seems to work ok:
HTML
<form id="test">
<select>
<option>uno</option>
<option>dos</option>
</select>
<input type="radio" name="videoDevice" value="tres" checked="checked" />
<input type="radio" name="videoDevice" value="cuatro" checked="checked" />
</form>
JS
document.getElementById('test').addEventListener('change', function() {
alert('change fired');
}, false);
Basically the form has only the following two events: onreset,onsubmit. You can do a workaround:
window.onload=(function ()
{
var Form=
{
w3c: !!window.addEventListener,
addEvent: function (form,type,listener)
{
var inputs=form.elements;
for (var i=0,l=inputs.length; i<l; ++i)
{
var input=inputs[i];
if (this.w3c)
{
input.addEventListener(type,listener,false);
}
else
{
input.attachEvent("on"+type,listener);
}
}
},
fixEvents: function (form)
{
var eventPattern=/^on(\w+)$/;
var attribute;
for (var i=0,l=form.attributes.length; i<l; ++i)
{
var attribute=form.attributes.item(i);
var name=attribute.name;
var value=attribute.value;
if (eventPattern.test(name) && !form[name])
{
var type=eventPattern.exec(name)[1];
var listener=new Function(value);
this.addEvent(form,type,listener);
}
}
}
};
return function ()
{
var forms=document.getElementsByTagName("form");
for (var i=0,l=forms.length; i<l; ++i)
{
Form.fixEvents(forms[i]);
}
};
})();
var button = document.form.adet;
if (button.addEventListener) { // all browsers except IE before version 9
button.addEventListener ("change", function () { alert('1'); }, false);
}
else {
if (button.attachEvent) { // IE before version 9
button.attachEvent ("onchange", function () { alert('2'); });
}
}
