I need help with passing a variable from an auto-generated button to another page when the button is clicked. The buttons all have the same link but different variables. How can I achieve this?
Once I generate the button, I assign it a function like so:
$('.Button').click(function() { window.location = 'page.html'; });
To achieve this, consider implementing a query string.
http://yourwebsite.com/page2.html?userID=5678
Here's an example approach based on your inquiry:
$('.Button').on('click', function() {
var userID = 5678;
window.location ='page.html?userID=' + userID;
});
If you're looking to achieve this solely with raw HTML and JavaScript, consider incorporating a hash into your webpage like demonstrated in the code snippet below:
onClick {
document.location = "/yourPage.html#id";
}
onLoad {
var id = window.location.hash;
}
Additionally, you have the option to store the ID in SessionStorage, LocalStorage, or Cookies.
If you are not concerned about the variable being public, you have the option of including it in the URL as a query string
http://domain/pagename.html?varname=2&othervar=2If the variable is on the same domain, you can store it in sessionStorage.
sessionStorage["varname"] = x;
One way to handle this is by passing the variable in the URL query string and retrieving it from there.
For example:
example.html?param=value
Alternatively, you could store the variable as a cookie with the key/value pair and access it when the page loads.
document.cookie = "param=" + value;
