Sending a duplicate JavaScript form
Hello, I have the following code and I want to avoid having to send the form in duplicate, replacing the "send" key with "sending ....". Thank you.
<DOCTYPE html>
<Html>
<Head>
<Meta charset = "UTF-8">
<Title> Browsing </ title>
<Form id = "form" action = "#">
<Input type = "button" value = "Send" onclick = "this.disabled = true; this.value = / 'Sending ... /'; this.form.submit ()" />
</ Form>
</ Head>
</ Html>
