Javascript 在EJS中单击“提交”按钮时无法提交表单

大家好，我遇到了一个问题，我不明白为什么，这是非常奇怪的，或者我写的代码错误，所以我希望你们能指出错误或启发我

因此，我试图将表单提交到数据库，在提交表单之前，validate函数将验证数据，如果出现错误，它将通知用户

当我单击“提交”按钮时，表单无法提交，并且没有发生任何事情，终端没有错误，控制台没有错误，看起来您在表单内部单击了什么，而表单希望提交表单>

这是完整的代码

我觉得这里没什么问题

  var express = require('express'),
         app = express(),
       http = require('http'),
       path = require('path'),
       MongoClient = require('mongodb').MongoClient,
       routes = require('./routes'),
       passport = require('passport');
    MongoClient.connect('mongodb://localhost:27017/test', function(err, db) {
        "use strict";
        if(err) throw err;
    // all environments
    app.set('port', process.env.PORT || 3000);
    app.set('views', __dirname + '/public/views');
    app.set('view engine', 'ejs');
    app.use('/static', express.static(path.join(__dirname, 'public')));
    app.use(express.cookieParser());
    app.use(express.favicon());
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.session({ secret: 'Super Duper Awesome Duck' }));
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(app.router);
    // development only
    if ('development' == app.get('env')) {
      app.use(express.errorHandler());
    }

    routes(app, db);

    http.createServer(app).listen(app.get('port'), function(){
      console.log('Express server listening on port ' + app.get('port'));
    });

    });

我认为这可能是一个愚蠢的错误。我希望我的HTML标记LOL没有问题。我相信您需要一个空间，以便type='submit'类变成：type='submit'类。

好的，在短暂的调试会话之后：

取自Angular的

由于表单在客户端应用程序中的作用是 与经典的往返应用程序不同，它适合 浏览器不将表单提交转换为整页重新加载 它将数据发送到服务器。取而代之的是一些javascript逻辑 应触发以在 特定于应用程序的方式

因此，Angular会阻止默认操作表单提交 除非元素具有action属性，否则不能将其复制到服务器 指定的

因此，您似乎没有为表单提交提供适当的处理：-

因此，要么提供一个，要么将“action”属性添加到表单中——这将修复它

如果这对你有意义，请告诉我

register.ejs中的表单标记中缺少action属性

应该是这样的

您可以通过单击处理程序从按钮提交表单，方法是查找表单并调用表单对象的提交方法。这不是一个EJS的东西，更只是一个简单的HTML的东西。请看：Nono我正在解释当我点击按钮时的感受确保你有一个动作=/在你的表单中注册；我完全误读了你最初的帖子。Hector很可能是正确的，没有定义任何操作，表单就不会去任何地方。@Hector Correa我可以在没有操作的情况下提交表单=/register，当然是在出现问题之前谢谢你回答我的问题，但它仍然保持不变，但在出现此问题之前，它工作得非常好。即使没有操作属性，也请在之前定义
