对于typescript用户

import react from 'react'

interface FormInterface {
    [key: string]: string
}

const handleSubmit = (event: React.FormEvent<HTMLFormElement>) => {
   event.preventDefault();
   let formData = new FormData(event.currentTarget)
   let formObj: FormInterface = {}
   for (let [key, value] of Array.from(formData.entries())) {
     formObj[key] = value.toString()
   }
};

<form onSubmit={handleSubmit}>
   <input type="text" name="email" placeholder="Email" />
   <input type="password" name="password" placeholder="Password" />
   <button type="submit">Login</button>
</form>

像这样给你的输入参考

<input type="text" name="email" placeholder="Email" ref="email" />
<input type="password" name="password" placeholder="Password" ref="password" />

然后你可以像soo一样在你的handleLogin中访问它

handleLogin: function(e) {
   e.preventDefault();
    console.log(this.refs.email.value)
    console.log(this.refs.password.value)
}

我认为这也是你需要的答案。此外，我在这里添加了所需的属性。每个输入组件都是函数。你需要在这里加入你自己的逻辑。

handleEmailChange: function(e) {
    this.setState({email: e.target.value});
},
handlePasswordChange: function(e) {
   this.setState({password: e.target.value});
},
formSubmit : async function(e) {
    e.preventDefault();
    // Form submit Logic
  },
render : function() {
      return (
        <form onSubmit={(e) => this.formSubmit(e)}>
          <input type="text" name="email" placeholder="Email" value={this.state.email} onChange={this.handleEmailChange} required />
          <input type="password" name="password" placeholder="Password" value={this.state.password} onChange={this.handlePasswordChange} required />
          <button type="button">Login</button>
        </form>);
},
handleLogin: function() {
    //Login Function
}

我像这样使用React Component state:

<input type="text" name='value' value={this.state.value} onChange={(e) => this.handleChange(e)} />

handleChange(e){
   this.setState({[e.target.name]: e.target.value})
}`

我建议采取以下方法:

import {Autobind} from 'es-decorators';

export class Form extends Component {

    @Autobind
    handleChange(e) {
        this.setState({[e.target.name]: e.target.value});
    }

    @Autobind
    add(e) {
        e.preventDefault();
        this.collection.add(this.state);
        this.refs.form.reset();
    }

    shouldComponentUpdate() {
        return false;
    }

    render() {
        return (
            <form onSubmit={this.add} ref="form">
                <input type="text" name="desination" onChange={this.handleChange}/>
                <input type="date" name="startDate" onChange={this.handleChange}/>
                <input type="date" name="endDate" onChange={this.handleChange}/>
                <textarea name="description" onChange={this.handleChange}/>
                <button type="submit">Add</button>
            </form>
        )
    }

}

这可能会帮助Meteor (v1.3)的用户:

render: function() {
    return (
        <form onSubmit={this.submitForm.bind(this)}>
            <input type="text" ref="email" placeholder="Email" />
            <input type="password" ref="password" placeholder="Password" />
            <button type="submit">Login</button>
        </form>
    );
},
submitForm: function(e) {
    e.preventDefault();
    console.log( this.refs.email.value );
    console.log( this.refs.password.value );
}
