在地图中显示带有对象值的单选按钮 javascript

Question

我有一个对象 'obj' 并且需要为每个对象显示单选按钮。对于每个对象，显示两个单选按钮，当 i select radio button , for id"trans", it changes/reflects the other

  handleSend(){
    var selected_sendoption = this.shadowRoot.querySelector('input[name = "sending"]:checked').value;
    this.service_send = this.shadowRoot.getElementById("paymentservice_receive");
    this.service_send.innerHTML = selected_sendoption;
    this.selectedsend = selected_sendoption;
  }
render(){
return html`
   ${obj.map((pr)=>{
     <div class="form-check" @click=${this.handleSend}>
       <input class="form-check-input" name="sending" type="radio" id="provider-send-${obj.id}" value="trans">Trans
       <input class="form-check-input" name="sending" type="radio" id="provider-send-${obj.id}" value="insta">Insta
   </div>
<p id="service_send"></p> // display the selected radio button value for corresponding obj selected
   })
  }`;
}

var obj=[
{
    id:"id1",
    in:"trans" 
},
{ 
  id:"id2",
  in:"insta"
}
]

Expected Output:

Display radio buttons for id1

Display radio buttons for id2

Display selected radio buttons for corresponding id

Answer 1

我认为这会有所帮助:)

您需要 map 遍历数组
Return 使用 html
您想通过 id=${'..'}

这里是相关的changes/parts

render() {
  return html`
     ${obj.map((pr)=> html`
       <input id=${`provider-send-${pr.id}`} value=${`trans-${pr.id}`}>Trans
     `)
  `;
}
