<form id="form1" runat="server" onkeypress="return event.keyCode != 13;">

在HTML页面中添加此代码…它会使……输入按钮. .

如果你正在使用jQuery:

$('input[type=text]').on('keydown', function(e) {
    if (e.which == 13) {
        e.preventDefault();
    }
});

<form id="form1" runat="server" onkeypress="return event.keyCode != 13;">

在HTML页面中添加此代码…它会使……输入按钮. .

使用两个事件。which和event.keyCode:

function (event) {
    if (event.which == 13 || event.keyCode == 13) {
        //code to execute here
        return false;
    }
    return true;
};

使用TypeScript，避免多次调用该函数

let el1= <HTMLInputElement>document.getElementById('searchUser');
el1.onkeypress = SearchListEnter;

function SearchListEnter(event: KeyboardEvent) {
    if (event.which !== 13) {
        return;
    }
    // more stuff
}

原生js(获取api)

document.onload = (() => { alert('ok'); let keyListener = document.querySelector('#searchUser'); // keyListener.addEventListener('keypress', (e) => { if(e.keyCode === 13){ let username = e.target.value; console.log(`username = ${username}`); fetch(`https://api.github.com/users/${username}`,{ data: { client_id: 'xxx', client_secret: 'xxx' } }) .then((user)=>{ console.log(`user = ${user}`); }); fetch(`https://api.github.com/users/${username}/repos`,{ data: { client_id: 'xxx', client_secret: 'xxx' } }) .then((repos)=>{ console.log(`repos = ${repos}`); for (let i = 0; i < repos.length; i++) { console.log(`repos ${i} = ${repos[i]}`); } }); }else{ console.log(`e.keyCode = ${e.keyCode}`); } }); })(); <input _ngcontent-inf-0="" class="form-control" id="searchUser" placeholder="Github username..." type="text">
