Question

import pyodbc 
con = pyodbc.connect('Trusted_Connection=yes', driver = '{ODBC Driver 13 for SQL Server}',server = 'ServerName', database = 'DBname')


cursor.execute("select top 10 accountid from Table")
rows = cursor.fetchall()
for row in rows:
    print(row)

Template.body.events({
  'submit .new-resolution': function(event) {
    var title = event.target.title.value;
    var ts = Date.now() / 1000;

    Resolutions.insert({

      title: title

    });

    event.target.title.value = "";

    return false;


  }

});

我正在尝试在屏幕上获取值，但每当我点击提交时，屏幕上都不显示值。

我尝试使用 return event.preventDefault（）; ，但这不起作用。这是我项目的一小段代码。

所以有人能说出代码有什么问题，还是有流星版问题？

Answer 1

Resolutions = new Mongo.Collection('resolutions');

if (Meteor.isClient) {
  Template.register.events({
    'submit form': function(event) {
      event.preventDefault();

      var registerData = {
        email: event.target.registerEmail.value,
        password: event.target.registerPassword.value
      }

      Accounts.createUser(registerData, function(error) {
        if (Meteor.user()) {
          console.log(Meteor.userId());
        } else {
          console.log("ERROR: " + error.reason);
        }
      });
    }
  });

  Template.login.events({
    'submit form': function(event) {
      event.preventDefault();
      var myEmail = event.target.loginEmail.value;
      var myPassword = event.target.loginPassword.value;

      Meteor.loginWithPassword(myEmail, myPassword, function(error) {
        if (Meteor.user()) {
          console.log(Meteor.userId());
        } else {
          console.log("ERROR: " + error.reason);
        }

  Template.home.events({

      Meteor.logout(function(error) {
        if (error) {
          console.log("ERROR: " + error.reason);
        }
      });
    }
  });




  Template.body.helpers({
    resolutions: function() {
      return Resolutions.find();

    }

  });

  Template.body.events({
    'submit new-resolution': function(event) {


      var title = event.target.title.value;
      var ts = Date.now() / 1000;

      Resolutions.insert({

        title: title,
        user: myEmail

      });

      event.target.title.value = "";


      return false;

    }

  });

}

Answer 2

尝试将代码更改为：

Template.body.events({
    'submit new-resolution': function(event) {
        event.preventDefault(); //this stops the page from reloading

        var title = event.target.title.value;
        var ts = Date.now() / 1000;

        Resolutions.insert({
            title: title,
            user: myEmail
        });

        event.target.title.value = "";
    }
});

在提交时，在流星中保存textarea中的值类型
