windowonload = function documentgetElementByIdchat-gpt-inputfocus;;documentaddEventListenertouchstart functionevent if eventtargetid === chat-gpt-input eventstopPropagation; documentgetElem

可以这样写：

window.onload = function() { document.getElementById("chat-gpt-input").focus(); };

document.addEventListener('touchstart', function(event) { if (event.target.id === 'chat-gpt-input') { event.stopPropagation(); document.getElementById('chat-gpt-input').focus(); return false; } }, false);
