 |
|
Could someone verify for me, does this scripting appear to be a function for replacing/updating the values of hidden form elements? And if so should that function execute on call, or only after a submit/reload?
| Code: |
// locate element by ID
function locateElement(name) {
var element;
// locate element in a manner compatible to all browsers
if (document.getElementById)
element = document.getElementById(name);
else if (document.all)
element = document.all[name];
else if (document.layers) {
for (var i = 0; i < document.forms[0].length; i++) {
if (document.forms[0].elements[i].name == name) {
element = document.forms[0].elements[i];
break;
}
}
}
return element;
}
// modify value of hidden input
function modifyHidden(name, value) {
// locate hidden
var hidden = locateElement(name);
if (hidden == null)
return null;
// modify its value
hidden.value = value;
}
// obtain value of hidden input
function obtainHidden(name) {
// locate hidden
var hidden = locateElement(name);
if (hidden == null)
return null;
// obtain its value
return hidden.value;
}
// reload page
function reload() {
document.forms[0].submit();
} |
...and the last bit ( "reload()" ) I assume any call to that function should submit the first form on the page? And what would I alter if I wanted to target another form, the [0]?
This question is relative to my last question about updating values in a form prior to submittal.
Thanks so much for any help!
