javascript - How to replace the content in the <p> tag in JS. Please give me some advice.

<p id="rads" class="formStyle selectOrder">
        <p>
             <input type="radio"  name="question" value="oui" checked >选项1
        </p>
        <p>
            <input type="radio"  name="question" value="non" > 选项2
        </p>
        <p>
            <input type="radio"  name="question" value="non" > 选项3
        </p>
    </p>
    <button class="blueBtn" onclick = "init()">替换</button>
var radioData = [{name:'紧急', value:1}, {name:'重要', value:2}, {name:'普通', value:3}];
function init(){
    for(var  i=0;i<radioData.length;i++){
            var pArray = $("#rads p");
            var radioObj = radioData[i];
            pArray[i].value =radioObj.name+"";
            
    }
    
  }

Replace option 1, option 2, and option 3 with the radioData content in the data. Please guide me. My code does not work.

    var oBox = document.getElementsByTagName("p");

        var radioData = [{name:'紧急', value:1}, {name:'重要', value:2}, {name:'普通', value:3}];
      for(var i=0;i<radioData.length;i++){
          console.log(oBox)
          oBox[i].childNodes[2].nodeValue=radioData[i].name
      }

    function init(){
    var $pArray = $("#rads input");
    $pArray.each(function(index,item){
       radioData.forEach(function(item1,index1){
           $(item).val(item1.name);
       });
    });
  }

var radioData = [{name:'紧急', value:1}, {name:'重要', value:2}, {name:'普通', value:3}];

function init(){
    for (x in radioData) {
        $("#rads p").eq(x).text( radioData[x].name )
    }
}

</script>

    What you want to replace is the value of input, not the value of p, and get each input

    There is no big problem with your code, no major changes are needed
    pArray[i].innerHTML =radioObj.name+""; Just change the value to innerHTML

    Hello, in your question, you want to replace <input> 标签后面的文本，而不是标签的 value 值。
    所以，你使用 pArray[i].value =radioObj.name+""; which is incorrect.
    The following is the code I gave for reference only: 

    <!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <title>Demo</title>
    <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script>
</head>

<body>
    <p id="rads" class="formStyle selectOrder">
        <p>
            <input type="radio" name="question" value="oui" checked> 选项1
        </p>
        <p>
            <input type="radio" name="question" value="non"> 选项2
        </p>
        <p>
            <input type="radio" name="question" value="non"> 选项3
        </p>
    </p>
    <button class="blueBtn" onclick="init()">替换</button>
</body>
<script>
var radioData = [{
    name: '紧急',
    value: 1
}, {
    name: '重要',
    value: 2
}, {
    name: '普通',
    value: 3
}];

function init() {
    for (var i = 0; i < radioData.length; i++) {
        var pArray = $("#rads p");
        var radioObj = radioData[i];
        pArray[i].innerHTML = /\<.*\>/.exec(pArray[i].innerHTML)[0] + '&nbsp;' + radioObj.name;
    }
}
</script>

</html>
