UPDATE
Plain JS delegation
Add the eventListener to the UL to delegate the click even on dynamically inserted LIs:
document.getElementById("ul").addEventListener("click",function(e) {
var tgt = e.target;
if (tgt.tagName.toUpperCase() == "LI") {
tgt.parentNode.removeChild(tgt); // or tgt.remove();
}
});
jQuery delegation
$(function() {
$("#submitButton").on("click",function() {
var text = $("#item").val(); //getting value of text input element
var li = $('
').text(text)$("#ul").prepend(li);
});
$("#ul").on("click","li",function() {
$(this).remove();
});
});
Original answer
Since you did not mention jQuery
var listItems = document.getElementsByTagName("li"); // or document.querySelectorAll("li");
for (var i = 0; i < listItems.length; i++) {
listItems[i].onclick = function() {this.parentNode.removeChild(this);}
}
you may want to wrap that in
window.οnlοad=function() { // or addEventListener
// do stuff to the DOM here
}
Re-reading the question I think you also want to add that to the dynamic LIs
li.innerHTML = text; //inserting text into newly created
elementli.onclick = function() {
this.parentNode.removeChild(this);
// or this.remove(); if supported
}
Here is the complete code as I expect you meant to code it
window.οnlοad=function() {
var button = document.getElementById("submitButton");
button.onclick = addItem;
}
function addItem() {
var textInput = document.getElementById("item"); //getting text input
var text = textInput.value; //getting value of text input element
var ul = document.getElementById("ul"); //getting element
- to add element to
var li = document.createElement("li"); //creating li element to add
li.innerHTML = text; //inserting text into newly created
elementli.onclick = function() {
this.parentNode.removeChild(this);
// or this.remove(); if supported
}
if (ul.childElementCount == 0) { //using if/else statement to add items to top of list
ul.appendChild(li); // will add if count of ul children is 0 otherwise add before first item
}
else {
ul.insertBefore(li, ul.firstChild);
}
}
In case you want to use jQuery, the whole thing gets somewhat simpler
$(function() {
$("#submitButton").on("click",function() {
var text = $("#item").val(); //getting value of text input element
var li = $('
').text(text)
.on("click",function() { $(this).remove()});
$("#ul").prepend(li);
});
});
最后
以上就是哭泣心锁为你收集整理的html li onclick,javascript - Remove clicked
