In PHP, we can use the header() function to redirect the URL.
In HTML, we can use the meta tag to redirect the URL.
For more information, visit PHP/HTML – Redirect URL in Seconds
But sometimes, we want the redirection starts after the HTML body is loaded. This can be done by Javascript. Continue reading Javascript – HTML Redirect
The following Javascript function will redirect you to the previous URL when it is called.
function goToPreviousPage() {
history.go(-1)
}
Add a return button to your HTML page as follow.
<input type="button" name="returnButton" value="Return" onclick="history.go(-1);"/>
Done =)

<script type="text/javascript">
$(document).ready(function() {
/* The call will fail and the alert box will display immediately */
setTimeout(delayedAlert("Hi Eureka!"), 3000);
});
function delayedAlert(str) {
alert(str);
}
</script>

Convert String to Number using parseFloat() or parseInt()
/* parseFloat() */
parseFloat('1.45kg') // 1.45
parseFloat('77.3') // 77.3
parseFloat('077.3') // 77.3
parseFloat('0x77.3') // 0
parseFloat('.3') // 0.3
parseFloat('0.1e6') // 100000
/* parseInt() */
parseInt('123.45') // 123
parseInt('77') // 77
parseInt('077',10) // 77
parseInt('77',8) // 63 (= 7 + 7*8)
parseInt('077') // 63 (= 7 + 7*8)
parseInt('77',16) // 119 (= 7 + 7*16)
parseInt('0x77') // 119 (= 7 + 7*16)
parseInt('099') // 0 (9 is not an octal digit)
parseInt('99',8) // 0 or NaN, depending on the platform
parseInt('0.1e6') // 0
parseInt('ZZ',36) // 1295 (= 35 + 35*36)
