Look at document.createElement()and element.appendChild().
看看document.createElement()和element.appendChild()。
var newdiv = document.createElement("div");
newdiv.innerHTML = val;
document.getElementById("showselecteditems").appendChild(newdiv);
Because you will likely encounter this in the near future: You can remove any elementwith this code:
因为在不久的将来您可能会遇到这种情况：您可以element使用以下代码删除任何内容：
element.parentNode.removeChild(element);

Using createElement:
function selecteditems() {
var container = document.getElementById('showselecteditems');
for (var i=1;i<=53;i++) {
var fld = document.getElementById('timedrpact'+i);
if (fld) {
var div = document.createElement("div");
div.appendChild(document.createTextNode(fld.value));
container.appendChild(div);
}
}
}
Full version using cloneNode (faster) and eventBubbling
使用 cloneNode（更快）和 eventBubbling 的完整版本
var div = document.createElement("div");
var lnk = document.createElement("a");
var img = document.createElement("img")
img.className="remove";
img.src = "https://uperform.sc.gov/ucontent/e14c3ba6e4e34d5e95953e6d16c30352_en-US/wi/xhtml/static/noteicon_7.png";
lnk.appendChild(img);
div.appendChild(lnk);
function getInputs() {
var container = document.getElementById('showselecteditems');
for (var i=1;i<=5;i++) {
var fld = document.getElementById('timedrpact'+i);
if (fld) {
var newDiv = div.cloneNode(true);
newDiv.getElementsByTagName("a")[0].appendChild(document.createTextNode(fld.value));
container.appendChild(newDiv);
}
}
}
window.onload=function() {
document.getElementById('showselecteditems').onclick = function(e) {
e=e||event;
var target = e.target||e.srcElement;
// target is the element that has been clicked
if (target && target.className=='remove') {
parentDiv = target.parentNode.parentNode;
parentDiv.parentNode.removeChild(parentDiv);
return false; // stop event from bubbling elsewhere
}
}
getInputs();
}
