onclick function using ajax - php

Question

In my code having two radio buttons in form like
<input type="radio" required="required" id="bt" name="bt" value="1" checked="checked" onclick="window.location='<?php echo $_SERVER['REQUEST_URI']; ?>';" /> <span>Test1</span>
<input type="radio" required="required" id="bt" name="bt" onclick="Clear()" value="2" /> <span>Test2</span>
when i click on Test2 radio button the form having value will clear, for that i wrote code its working fine
<script>
function Clear() {
document.getElementsByName("one")[0].value = "";
document.getElementsByName("two")[0].value = "";
document.getElementsByName("three")[0].value = "";
}
</script>
with this form with values cleared.But when i click on "Test1" radio button the form values will come automatically.right now iam sessions using
onclick="window.location='<?php echo $_SERVER['REQUEST_URI']; ?>';"
for this it is coming but page is refreshing how to take it this code to ajax, i mean need to get values when i click on radio button without refreshing the page

Answer 1

Yes you can use window.location.href in ajax as:
$.ajax({
type: 'POST',
async: false,
url: '/users',
contentType: 'application/json',
dataType: 'json',
data: JSON.stringify(payload),
success: function(data, textStatus, jqXHR){
console.log(jqXHR.status);
window.location.href= "/someUrl.html";
}
});
Note that: window.location.href will not reload the page if there's an anchor (#) in the URL

Answer 2

Here i wrote code for getting values of radio button without page refresh:
html code:
<input type="radio" name="bt" id="bt" onclick = "MyAlert()" value="blue"/>Blue <br/>
<input type="radio" name="bt" id="bt" onclick = "MyAlert()" value="red"/>Red
ajax script:
function MyAlert() {
var radio =$('input[type="radio"]:checked').val();
var pass_data = {
'radio' : radio,
};
$.ajax({
url : "radio-value.php",
type : "POST",
data: pass_data,
success : function(data) {
// alert radio value here
alert(data);
}
});
return false;
}
radio-value.php file:
<?php echo $bt =$_POST['radio']; ?>
Hope this helps.
