I am trying to make a form in html that uses the value you enter to form the destination URL.
<form action="../search/${params.q}" method="post" id="q">
Busqueda: <input type="text" name="q" /><br />
</form>
This is what i am doing, but it does not work, any cluess? thanks!
You'd need to handle this using a script - either server-side or on the client (JavaScript).
HTML alone can't handle parameters in the way you're using them.
So you'd need to either POST the form (as you're already doing) and handle the postback by redirecting your request to the new address, or use JavaScript to capture the field's value when a submit button is clicked and loading the new address in the browser window.
I'd suggest server-side is the best option as JavaScript might be disabled or unavailable.

I am having a form and in that checkbox and button is present, on click of button, the data are submitting and also inserting in database, but my page is refreshing, I want my data should submit and insert in database and also page should not refresh in thymeleaf spring boot. The values in checkbox are displaying in loop. My current code is:
<form class="myform myform-newaccount" action="#" id="myForm"
th:action="#{/authorList?buttonValue=pluginlist}"
th:object="${userModifyDto}" method="post">
<input type="checkbox" name="applicationId" th:field="*{applicationIds}" id="myCheck"
th:value="${option.applicationId}" />
<input type="submit" value="send" id="myid"/>
</form>
The default behaviour of server-side rendering technology such as Thymeleaf is that actions always trigger a page refresh. See Form handling with Thymeleaf for more information on that.
That said, there are 2 options:
Use JavaScript (either plain JS or a framework) to do AJAX requests and avoid the page refreshes.
Use hx-boost from the htmx library. This will make it seem like there is no page refresh by intercepting the form submit and doing the request to the server via an AJAX call. See TodoMVC with Thymeleaf and HTMX for more information on that option.
I want to send an email which has a submit button, on click of which, a post request would be triggered.
How can I create such an email?
What kind of code would be required?
The code I have written:
<h1>Show a push button:</h1>
<p>The button below activates a JavaScript when it is clicked.</p>
<br/>
<input type="button" value="Click me" onclick="msg()">
That approach you appear to be trying to take is to use JavaScript. This absolutely will not work. Email clients do not allow JavaScript to execute in HTML formatted email.
You could place a regular form inside the email:
<form action="http://example.com" method="POST">
<button>Submit</button>
</form>
… however, form support in email clients is not perfect.
The safe approach is to ask the user to do a two-step process: use a regular link to a webpage containing the form which the user can load in their web browser and then click the submit button for.
If you don't care about the usual protections, then you could have JavaScript submit the form on that page automatically, or change the endpoint that expects a POST request to expect a GET request and use a regular link in the original email.
I want my users to write his website on my site and then be sent to gtmetrix.com to start a new test, but without needing to write his website again.
I am trying with this:
<form method="post" action="https://gtmetrix.com/analyze.html">
<input type="text" placeholder="Enter your Website URL"></input>
<input type="submit">CHECK IT</input>
</form>
But i get a
Analysis Error
You tried to analyze an invalid/malformed URL
What i am doing wrong? is possible to do this?
It seems they require the url in the form data field called url.
You must use the following input tag:
<input type="url" name="url" value="" placeholder="Enter your website URL" maxlength="1024" autofocus="" required="">
Also, they could be blocking external referrers. But first try adding the name attribute.
First of all, I don't know if that website allows you to submit that form from external websites. Make sure that's possible!
Seccond of all, you are trying to sent a form without setting the name of the input field. The resource that receives your request don't know anything to do with it.
If you want to analyse websites on your own website, search for services that provide APIs for using it external.
I am not familiar with gtmetrix, but you need to set the name attribute on your input to send it with the request.
I have a jsp form in which a user can signup by entering username and password. I have to check dynamically whether the username exists in mysql database as the username is typed into the text box. Here is a sample code:
<html>
<head>Sample Signup</head>
<body>
<form action="updatedb.jsp" method="post">
Username : <input type="text" name="uname">
<br>
Password : <input type="text" name="upass">
<br>
<input type="submit" value="signup">
</form>
</body>
</html>
I am new to jsp so an elaborated answer will be more helpful. If i missed any other important info, ask me right away.
Java cannot respond to the client-side methods like onChange (not directly). Those methods call Javascript. Javascript is not actually related in any way to Java; its only called that because it uses the bracket-style syntax for functions as opposed to VB-style syntax. The only way to involve Java itself in the client-side methods would be to use Javascript to send an Ajax request to a JSP/Servlet and receive a response back. The simplest way to send an Ajax request in Javascript is with jquery (a javascript library).
I am sending a form post to a third party and it is returning a page with Success if the action is done. Once I get the success page, I need to redirect user to a Thank You page. Can somebody tell me how the see if the success page is returned and redirect to another page?
<form name="abc" method="POST" action="third party url" >
<input />
<input />
</form>
... how about submitting the form and receiving response in an iframe? If you can use an iframe you'll be able to detect the change then.
the code goes like this:
<form name="abc" method="POST" action="third party url" >
<input/>
<input/>
</form>
but i am not sure how to capture the response
You won't be able to do this easily with plain javascript. When you post a form, the form inputs are sent to the server and your page is refreshed - the data is handled on the server side. That is, the submit() function doesn't actually return anything, it just sends the form data to the server.
If you really wanted to get the response in Javascript (without the page refreshing), then you'll need to use AJAX, and when you start talking about using AJAX, you'll need to use a library. jQuery is by far the most popular, and my personal favourite. There's a great plugin for jQuery called Form which will do exactly what it sounds like you want.
