Hello guys I'm trying to create a function to get the full link if it has #mystring is exists for example
but when I split it shows me errors
Uncaught TypeError: can't access property "split", data[1] is undefined
function my_function() {
var link = window.location +''; // get website link as string www.mydomain.com
var data = link.split("#"); // start link after # for example www.mydomain.com/#mystring&anotherstring=hello
var widget_type = data[1].split("&")[0]; // to get "mystring"
if(widget_type == 'mystring') { // check if "mystring" in the link exists
var link = window.location.hash.substr(1); // get full link
console.log(link)
}
}
my_function();
so how can i check if "#mystring" is exits in my link before do it and fix split error?
If the link doesn't contain #, the data array after splitting will contain only one item which is the link, So you need to check if there is a second item in the data by optional chaining after data[1]
var widget_type = data[1]?.split("&")[0]
Or you can use if condition.
const path = data[1]
var widget_type = '';
if (path) {
widget_type = path.split("&")[0];
}
