I have a bit of a tricky work problem I hope to get some help with.
To handle various forms and storing entries, we use an in-house tool which I cannot modify. Basically what happens is:
- I enter he URL the original page, and the URL of the destination page after successful submission.
- The tool spits out some HTML and Javascript code, the most important of which is a unique URL, let's call it (redactedURL), that goes after the action attribute.
- When the form is submitted, the page will refresh to one of two possible destination URLs: the one I inputted if success, or (redactedURL) if error.
- I can download all the entries from the tool afterward.
The HTML is quite simple. checkform() is a simple validation script.
<form action="(redactedURL)" name="enenForm" method="POST" onSubmit="return checkForm()">
The issue with this is that I can't style the (redactedURL) error page, which is quite ugly. I am wondering if there is anyway I could
- Suspend automatic display results of form submission
- Determine the destination URL, and based on that, write out a custom thank you/error message (since I cannot access the server-side script, this seems to be the only solution to determine if the submission is successful or not).
- Make sure that tool still properly stores all the entries.
Any help would be much appreciated. Thanks!
Don't use a form. Instead use AJAX. I think this SO Question will provide a start. Basically you use JavaScript to submit data to a server using XMLHttpRequest. The returned HTML is a string which you could either modify or (better yet) normalize and add to the DOM.
For an advanced example jQuery-Mobile does this concept when you click a link instead it gets the HTML from the server as an AJAX request copies the HTML inside the
<body>and inserts it into the DOM.Search for tutorials about AJAX and jQuery (or your prefered JS library). Like this one.
