我正在尝试创建一个应用程序来跟踪网页，当用户添加新 URL 时，链接将显示在输入框下方的网页上。 我想将 URL 转换为“ anchor ”标签并将标签作为字符串存储在数组中。 我可以获得输出，但我不知道如何将 url 转换为 achor 标记。 这就是我对 html 和 javascript 的看法。 总的来说，我正在尝试修改超链接，以便当用户选择链接时，该页面将出现在新选项卡中。要启用此功能，例如“”标签内的“target=”_blank”。

displayRadiobuttons+=clientlist+"<br>";
}
//display list
document.getElementById("showlist").innerHTML=displayRadiobuttons;

//delete item from objectarry at index i using splice
function deleteItem(i) {
//delete ONE item at index i
objectarray.splice(i,1);
//display modified list
displayList();
}
最佳答案
在显示列表时，只需将单选标记与 a 标记括起来
var objectarray=[];//array
function addToArray() {
//read items from form and create client object
var clientobject={url};
//input variables into clientobject
clientobject.url=document.getElementById("url").value;
//alert("Client Name: "+clientobject.firstname+" "+clientobject.lastname);
//load into objectarray
objectarray.push(clientobject);
displayList();//display object array
}
function displayList() {
//variables
var clientlist="";//this will be the list of elements in the array list
var displayRadiobuttons="";//display elements as a list of radio buttons
for (var i=0;i<objectarray.length;i++)
{
//local instance of clientobject
var clientobject={url};
clientobject=objectarray[i];
clientlist= clientobject.url;
//create radio button tags and elements
displayRadiobuttons+="<a href=https://"+clientobject.url+" target='_blank'><input type=radio name=listitem ";
displayRadiobuttons+=" value="+i+" ";
displayRadiobuttons+=" onchange=deleteItem(this.value)>";
displayRadiobuttons+=clientlist+"</a><br>";
}
//display list
document.getElementById("showlist").innerHTML=displayRadiobuttons;
}
//delete item from objectarry at index i using splice
function deleteItem(i) {
//delete ONE item at index i
objectarray.splice(i,1);
//display modified list
displayList();
