I'm just learning javascript and php. I created a contact form and I'd like the submit button to accomplish two things when I press it:
- submit the data to me (this part is working)
- read my onclick function (this part is not working)
<input id="submit" name="submit" type="submit" value="Submit" onclick="eatFood()">
<?php
if ($_POST['submit']) {
////?????
}
?>
I'm sending the data to my email, and so I get that. But the onclick function doesn't seem to work. I tried reviewing add onclick function for submit button but it didn't help.
I need to see your submit button html tag for better help. I am not familiar with php and how it handles the postback, but I guess depending on what you want to do, you have three options:
- Getting the handling
onclick button on the client-side: In this case you only need to call a javascript function.
function foo() {
alert("Submit button clicked!");
return true;
}
<input type="submit" value="submit" onclick="return foo();" />
If you want to handle the click on the server-side, you should first make sure that the form tag method attribute is set to post:
<form method="post">
You can use onsubmit event from form itself to bind your function to it.
<form name="frm1" method="post" onsubmit="return greeting()">
<input type="text" name="fname">
<input type="submit" value="Submit">
</form>
html:
<form method="post" name="form1" id="form1">
<input id="submit" name="submit" type="submit" value="Submit" onclick="eatFood();" />
</form>
Javascript:
to submit the form using javascript
function eatFood() {
document.getElementById('form1').submit();
}
to show onclick message
function eatFood() {
alert('Form has been submitted');
}
if you need to do something before submitting data, you could use form's onsubmit.
<form method=post onsubmit="return doSomething()">
<input type=text name=text1>
<input type=submit>
</form>
<button type="submit" name="uname" value="uname" onclick="browserlink(ex.google.com,home.html etc)or myfunction();"> submit</button>
if you want to open a page on the click of a button in HTML without any scripting language then you can use above code.
