如何删除页面加载时的单选按钮值。单选按钮列表如此动态我必须删除此值<input type="radio" name=myradio value="Null">Null

<input type="radio" name=myradio value="Bill">one
<input type="radio" name=myradio value="Sale">two
<input type="radio" name=myradio value="Null">Null

Answer 1

你可以试试这个 - 首先制作一个Javascript函数，如：

<script>
    function remvalue()
        {
    document.getElementById('myradiobutton').value="";

    }
window.onload=remvalue;
</script>

然后将ID分配给单选按钮：

<input type="radio" id=myradiobutton name=myradio value="Null">Null

Answer 2

window.onload = function() {
    var myradios= document.getElementsByName('myradio'); //Get all myradio elements from document

    for (var i = 0; i < myradios.length; i++) { //Loop all myradio elements
        if (myradios[i].value == 'Null') { //If value of element == null
            myradios[i].parentNode.removeChild(myradios[i].nextSibling); //Removes the "Null"-Text
            myradios[i].parentNode.removeChild(myradios[i]); //Removes the radio button
        }
    }
}
