windw.location.href不在Local主机上工作

Question

window.location.href 对我不起作用：/everthin 正在运行 带有“xampp”的本地主机

//javascript function 1
function onLogin() {
    window.location = "http://localhost:4000/deletetable";
    console.log("running...");
    console.log(window.location.href);
    return false;
}


// !node.js! function 2 in other file(server.js)
//Delete Table
app.get('/deletetable', (req, res) =>{
    let sql = 'DROP TABLE IF EXISTS users';
    db.query(sql, (err, result) => {
        if(err) throw err;
        console.log(result);
    });
});


//html...
<form onsubmit="onLogin();">
    <div class="wrapper">
       <button class="downloaded-btn"></button>
    </div>
</form>
//only a button...

我尝试了 url window.location.href =“url” 中的所有内容，但没有任何效果。感谢您的帮助！

如果您想允许用户向后导航，请使用window.location.assign =“ http：// localhost：4000/deletetable

” “ rel =“ nofollow noreferrer”> https://www.w3schools.com/jsref/met_loc_assign.asp

//javascript function 1
function onLogin() {
  console.log("running...");
  return window.location.assign="http://localhost:4000/deletetable";
}


// !node.js! function 2 in other file(server.js)
//Delete Table
app.get('/deletetable', (req, res) =>{
    let sql = 'DROP TABLE IF EXISTS users';
    db.query(sql, (err, result) => {
        if(err) throw err;
        console.log(result);
    });
});


//html...
<form onsubmit="onLogin();">
    <div class="wrapper">
       <button class="downloaded-btn"></button>
    </div>
</form>
//only a button...

否则，如果您不想允许用户向后导航，请使用：window.location.replace =“ http：//localhost：4000/deletetable”

https://www.w3schools.com/jsref/met_loc_replace.asp

//javascript function 1
function onLogin() {
 console.log("running...");
 return window.location.replace ="http://localhost:4000/deletetable";
}


// !node.js! function 2 in other file(server.js)
//Delete Table
app.get('/deletetable', (req, res) =>{
    let sql = 'DROP TABLE IF EXISTS users';
    db.query(sql, (err, result) => {
        if(err) throw err;
        console.log(result);
    });
});


//html...
<form onsubmit="onLogin();">
    <div class="wrapper">
       <button class="downloaded-btn"></button>
    </div>
</form>
//only a button...
