[英]Showing input value in the url link (ReactJs Laravel)
我使用reactjs框架創建了laravel項目,而我是這個框架的新手。 我有問題,為什么每次提交表單時都會發生。
目標:用戶可以通過在線注冊
問題:
碼:
constructor() {
super();
this.state = {
f_name:'',
l_name:'',
m_name:'',
email:'',
home_num:'',
contact_num:'',
Job_name:[],
employ_status:'',
employ_relocate:'',
employ_start_date:'',
employ_file:''
}
this.handleSubmit = this.handleSubmit.bind(this);
this.handle_fname = this.handle_fname.bind(this);
this.handle_lname = this.handle_lname.bind(this);
this.handle_mname = this.handle_mname.bind(this);
this.handle_email = this.handle_email.bind(this);
this.handle_homenum = this.handle_homenum.bind(this);
this.handle_contactnum = this.handle_contactnum.bind(this);
this.handle_employ_status = this.handle_employ_status.bind(this);
this.handle_employ_relocate = this.handle_employ_relocate.bind(this);
this.handle_employ_start_date = this.handle_employ_start_date.bind(this);
this.handle_employ_file = this.handle_employ_file.bind(this);
}
componentDidMount() {

axios.get('/api/online_application_job_title/' +id).then(response => {
this.setState({

}
使用表單標簽時,提交將觸發基於提供的方法和操作URL的默認行為。 就像在您的示例中一樣,您正在顯式處理數據,因此應防止默認行為。 在句柄提交中添加以下代碼
handleSubmit(e) {
e.preventDefault();
...
...
}
這將防止默認行為。
狀態更新的改進:您不需要單獨的功能來更新輸入值即可聲明可以將其組合為一個功能。 要組合,請提供與狀態名稱相同的輸入名稱。
this.state ={
"f_name": '',
"l_name": '',
...
}
<input name="f_name" ... onChange={this.handleInputChange}/>
<input name="l_name" .. onChange={this.handleInputChange}/>
handleInputChange(e){
let target = e.target;
let name = target.name;
let value = target.value
this.setState({[name]: value})
}
有關更多信息,請參考此鏈接 。
首先,我只想向您介紹JavaScript(ES6)中的arrow函數 。 聲明這樣的私有方法:
handle_fname = (e) =>
{
this.setState({
f_name:e.target.value,
})
}
將節省您不必要的構造器綁定時間。
關於您的問題,您錯過了顯示this.handleSubmit()
的內容。 沒有這個,我可以假設表單提交觸發了一個get
調用,因為您未能將method
屬性放置在<form/>
標記中,並且沒有指明您的method屬性將導致默認的get method。 使用get方法時,提交的數據將在瀏覽器的頁面地址字段中可見。
編輯
您已經在問題中添加了handleSubmit()
,看起來還可以。 如果數據仍顯示在瀏覽器的地址字段中,請嘗試在表單標簽中添加method="post"
,如下所示:
<form onSubmit={this.handleSubmit} method="post">
