how to reset form in firefox browser by javascript
I want to reset form in firefox browser. When I use previous function in back button, the page is not reset for hidden field. It has previous stage. So, How do I?
<Html>
<Head>
<Title>My Testing for javascript</Title>
<Script type="text/javascript">
function hidetext(){
window.alert('Start save to hidden');
document.getElementById('hid').value = document.getElementById('puttextbox').value;
window.alert('Complete save to hidden');
document.getElementById('puttextbox').value='';
}
function displaytext(){
window.alert('Start display from hidden');
document.getElementById('displaytextbox').value = document.getElementById('hid').value;
window.alert('Complete displ开发者_如何学Pythonay from hidden');
}
function resetform(){
document.getElementById('form1').reset();
window.alert('reset is completing.....');
}
</Script>
</Head>
<Body>
<form id="form1">
<div>
Type your hidden text <input type="text" id="puttextbox"/>
<br/>
Display your hidden text <input type="text" id="displaytextbox"/>
<br/>
<input type="hidden" id="hid"/>
<button type="button" id="putbutton" onclick="hidetext();">Put the textbox</button>
<button type="button" id="displaybutton" onclick="displaytext();">Display hidden text</button>
<button type="button" id="resetbutton" onclick="resetform();">Reset</button>
</div>
</form>
</Body>
</Html>
Why not this:
<input type="reset" value="Reset">
? It's HTML-native. Or try this instead:
window.onload = function() {
var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; i++) {
inputs[i].value = '';
}
};
It clears each input element in the page.
function clearForm(oForm) {
var elements = oForm.elements;
oForm.reset();
for(i=0; i<elements.length; i++) {
field_type = elements[i].type.toLowerCase();
switch(field_type) {
case "text":
case "password":
case "textarea":
case "hidden":
elements[i].value = "";
break;
case "radio":
case "checkbox":
if (elements[i].checked) {
elements[i].checked = false;
}
break;
case "select-one":
case "select-multi":
elements[i].selectedIndex = -1;
break;
default:
break;
}
}
}
That should do the job.
The most simple version is:
document.form1.reset();
However, this resets all input fields to their default value, i.e. the one sent along with the HTML. If you want all fields cleared, you'd need to loop through them all.
