我正在使用ctrl + charCode**s 从列表页面中删除一行，该行在 firefox 上运行良好，但是当我在 **Chrome 上对其进行测试时，event.preventDefault()无法停止基于浏览器的功能过来
function showkey(e){
if(e.ctrlKey && e.charCode == 100){
e.preventDefault();
//delete code // }
<body onkeypress="showkey(event);">
You can acheive with jQuery. Include jQuery library
$(document).bind('keydown', function(e) {
if(e.ctrlKey && (e.which == 100)) {
e.preventDefault();
return false;
}
});
This works :)
look this answer Override the bookmark shortcut (Ctrl+D) function in Chrome
working solution just tested on this page
document.addEventListener('keydown', function(event) {
if (event.ctrlKey && String.fromCharCode(event.keyCode) === 'D') {
console.log("you pressed ctrl-D");
event.preventDefault();
event.stopPropagation();
}
}, true);
