In the past, whenever I needed to get the value of an html element, I would always submit a form to load a different page. Something like:
page1.php
page2.php
My question is, is it possible to get the value of 'input1' on the same page [page1.php] without requiring clicking a submit button?

With jQuery:
Response from server:
$.post['test.php',{'data': "value1"}, function [data] {
$['#response'].text[data];
}];
Non-jQuery IE doesn't have the XMLHttpRequest object so here is a shim for IE:
Yes, using ajax / javascript:
var formData = new FormData[];
formData.append["input1", "value1"];
var xhr = new XMLHttpRequest[];
xhr.open["POST", "page1.php"];
xhr.send[formData];
if [typeof XMLHttpRequest == "undefined"] XMLHttpRequest = function[] {
try {
return new ActiveXObject["Msxml2.XMLHTTP.6.0"];
}
catch [e] {}
try {
return new ActiveXObject["Msxml2.XMLHTTP.3.0"];
}
catch [e] {}
try {
return new ActiveXObject["Microsoft.XMLHTTP"];
}
catch [e] {}
//Microsoft.XMLHTTP points to Msxml2.XMLHTTP and is redundant
throw new Error["This browser does not support XMLHttpRequest."];
};

What for? Do you want to submit it to another file without needing to actually "submit" the form?
You use JavaScript for that.
document.form1.input1.value
