Force a Submit on a form load?

By 3wadman ·
How can you click a SUBMIT button using CODE?

I would like to use a form POST or GET in a ASP page without needing the visitor to click the Submit button.

In VB you can click any button by changing the VALUE of the object. Seems like either (windows.object.submit = True or document.all.object(1) = -1) VBSCRIPT or JSCRIPT should be able to trick the browser into sending its 'pair values' to another ASP page.

Force a Submit on a form load?

by b1xml2 In reply to Force a Submit on a form ...

Try this:-
<html>
<head>
<title>Conditional Submission</title>
<script language="javascript">
var regTrim = /(^\s+)|(\s+$)/g;
function checkData(e) {
trim(e);
if (e.value != "") document.data.submit();
}

//for browsers that support regular expressions
function trim(e) {
var szValue = new String(e.value);
szValue = szValue.replace(regTrim ,"");
e.value = szValue;
}
</script>
</head>
<body bgcolor="#ffffff">
<form name="data" method="get" action="request.asp">
Search: <input type="text" name="search" onchange="checkData(this);">
</form>
</body>
</html>

Notes:-
------
1. It is considered bad "form" (pun intended!) to submit forms without user action.
2. The onchange event is used for input types:- text, password as well as select and textarea elements.
3. The onclick event is used for input types radio and checkbox.
4. Cross browser scripting would require you to check the type. If the supported browsers implement DOM properly, you can check the element.tagName instead of the element.type.
Select elements have two values: select-one and select-multiple.
5. To submit a form via code, use the document.formName.submit() method.
6. It is good to have some validation, trimming leading and trailingspaces client-side. Saves work on the server.
7. Regular Expression is supported in Javascript 1.2 and above. You would have to write your own function
to trim values for older browsers using the substring and charAt methods.

Sorry, this forces the user to gain and loose focus on the input box.

To post a GET to an ASP page, just append the parameters to the URL, like so:

http://www.blabla.com/mypage.asp?textbox1=name&textbox2=address&textbox2=city . . .

To post a POST to an ASP page, use a JavaScript snippet something like so (assuming your form's name was "form1"):

<script language="javascript">
document.form1.Submit();
</script>

That worked well, thanks!

FYI: Form POST is the only easy way to securely send record set fields from a SQL to a SSL without the users knowledge.(You lose your seesion variables when you go from non-SSL to SSL)
