javascript/ajax to mysql db

[acoder]

The reason it opens a new window is the target attribute. If you remove that, it won't open a new window. However, having said that, onsubmit should be added to the form tag, not the submit button. Remind me, did you want to prevent a page unload completely or did you want to make one submit (with Ajax) and then another page unload/reload one later with Paypal?

Note: 'urlparams' should be just urlparams without the quotes.

i just want to save the form data to a db whilst paypal opens in a new window....nothi ng to do with paypal is going to change, just need to be able to get it to send data to db in the same page or in a seperate page.

change httpRequest.sen d('urlparams'); to httpRequest.sen d(urlparams);

I just noticed that when you call makeRequest(), you're passing an empty string instead of the URL.

[anfetienne]

ok so i have to take away the quotes on urlparams and makeRequest() should be makeRequest(url )?

[acoder]

Yes and no. Pass the actual URL as a string, e.g.

makeRequest('test.php')

[anfetienne]

ok will do a test and let you know the results

i can't get this to work on submit.....

how many functions can i have on one action?

[acoder]

As many as you want; you must be returning from one of the functions. Post your code.

[anfetienne]

its the same code as what i posted earlier there is no change.....id just like to know how many functions i can run in a onclick and how.

do i seperate with commas? eg onclick="func1 , func2"

You separate them, like you would normal statements in the language, i.e. with semi-colons.

<a href="#" onclick="alert('hi'); func1(); func2(); return false;">...</a>

[anfetienne]

is it possible to do the same using onclick within a form? sorry, i should of phrased myself properly before

It's possible with any element. Learn by trying, anfetienne. ;)

[anfetienne]

lol i know the saying.....just needed to know if it was possible

thanks for the help

[anfetienne]

I've tested this and it does not work....i have tried using onsubmit, onclick, onmousedown, onmouseup and it still doesn't do anything.

i.e. onsubmit="makeR equest('data.ph p')"

here is my coding....am i doing something incorrectly?

<script type="text/javascript" language="javascript">
    function makeRequest(url) {
        var httpRequest;

        if (window.XMLHttpRequest) { // Mozilla, Safari, ...
            httpRequest = new XMLHttpRequest();
            if (httpRequest.overrideMimeType) {
                httpRequest.overrideMimeType('text/xml');
                // See note below about this line
            }
        } 
        else if (window.ActiveXObject) { // IE
            try {
                httpRequest = new ActiveXObject("Msxml2.XMLHTTP");
            } 
            catch (e) {
                try {
                    httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
                } 
                catch (e) {}
            }
        }

        if (!httpRequest) {
            alert('Giving up :( Cannot create an XMLHTTP instance');
            return false;
        }
		
		//enter var details for fields here
		var urlparams = "first_name=" + encodeURIComponent(document.getElementById("first_name").value);
		urlparams += "&last_name=" + encodeURIComponent(document.getElementById("last_name").value);
		urlparams += "&address1=" + encodeURIComponent(document.getElementById("address1").value);
		urlparams += "&address2=" + encodeURIComponent(document.getElementById("address2").value);
		urlparams += "&city=" + encodeURIComponent(document.getElementById("city").value);
		urlparams += "&state=" + encodeURIComponent(document.getElementById("state").value);
		urlparams += "&zip=" + encodeURIComponent(document.getElementById("zip").value);
		urlparams += "&os0=" + encodeURIComponent(document.getElementById("os0").value);
		urlparams += "&email=" + encodeURIComponent(document.getElementById("email").value);

		
        httpRequest.onreadystatechange = function() { alertContents(httpRequest); };
        httpRequest.open('POST', url, true);
        httpRequest.send('urlparams');

    }

    function alertContents(httpRequest) {

        if (httpRequest.readyState == 4) {
            if (httpRequest.status == 200) {
                alert(httpRequest.responseText);
            } else {
                alert('There was a problem with the request.');
            }
        }

    }
