我想在用户点击右侧的红色十字按钮时删除列表项， 我为每个列表项动态添加了关闭按钮。 如何定位我添加到＆＃39; a＆＃39;标签＆＃39;点击链接＆＃39;从功能外部？
我想用纯粹的javascript实现这个目标
由于
(function(){
var clickGo = document.querySelector('.button-go');
var searchInput = document.querySelector('.search-input');
var list = document.querySelector('.list');
var listArray = [];
var clickGoFunc = function() {
var searchValue = searchInput.value;
// check if input field is empty
if(searchValue === ""){
alert("please put a value in the input field");
}else{
// check if list item already exists in the array named listArray
if(listArray.indexOf(searchValue) == -1){
listArray.push(searchValue);
// Function for creating loop for added array items and enclosing each array item inside <li>
//Also adding a close button to each array item by adding <a> Tag
var runIt = function (){
for(var i= 0; i < listArray.length; i++ ){
var liTag = document.createElement('li');
var removeItem = document.createElement('span');
var closeLink = document.createElement('a');
closeLink.className = "close-link";
closeLink.setAttribute('href', "#");
closeLink.textContent = 'X';
// adding <a> tag inside span
removeItem.appendChild(closeLink);
liTag.textContent = listArray[i].toUpperCase();
list.appendChild(liTag);
liTag.appendChild(removeItem);
list.appendChild(liTag)
}
// end of for loop
};
// end of runit
// clearing ul.list container before reloading array items.
list.innerHTML = "";
// calling runIt funtion which contains for loop for all the array items
list.appendChild(runIt());
}else{
alert("value already exisits");
}
// end of if and else statement which is checking if value is already there is the array
// pushing new values in the listArray array
// wrapping new array items in li tags and adding close button on each array item
}
// if statement checking if the input field is empty , if not it runs other function which checks following
// end of if and else statement which is checking if value is already there is the array
// pushing new values in the listArray array
// wrapping new array items in li tags and adding close button on each array item
}
// end of clickGoFunc
//calling function
clickGo.addEventListener('click', function(){
clickGoFunc()
});

使用jQuery，选择具有类.close-link的所有标记，并将事件绑定到click方法。
如果您需要从标记遍历以转到其li。你设置它的方式是这样的：
<li><span><a></a></span></li>
两个父母，所以使用：
$(this).parent().parent()
现在已选中点击的li的父a。致电.remove()以删除它及其所有孩子。最终结果：
$('.close-link').on('click', function(){
$(this).parent().parent().remove();
});
另外，我注意到你的css看起来像这样
HTML，身体，股利，跨度，小应用程序，对象，iframe中，H1，H2，H3，H4，H5 ...
CSS selectors可以在这里帮到你。在您的情况下，您想使用星号（*）来选择所有内容。

您只需向ConnectionSignUp.execute(Connection<?>) var添加onclick个事件即可删除closeLink。
