Display after refreshing, requires cookies, or save to the server.
I tried, but it didn’t work. I’m not very familiar with cookies. Can you be more specific?
When refreshing and reloading, first get the value from the cookie, and assign it to the drop-down box if it is obtained. If it cannot be obtained, it will be displayed by default
<!doctype html><html lang="en-US"><head> <meta charset="UTF-8"> <title></title></head><body><input type="text" name="" id="txt"/><input id="btn" type="button" value="test"/><script type="text/javascript"> document.getElementById('btn').onclick = function(){ var d = new Date(); d.setDate(d.getDate() + 10); document.cookie = 'value=' + document.getElementById('txt').value + ';expires=' + d; console.log(document.cookie); }</script></body></html>
