我无法弄清楚如何做到这一点,好吧,需要帮助。 我正在尝试将我的信息放入一个将要显示的数组中,并始终能够增长。我需要帮助删除特定条目,通过搜索一个或通过指向鼠标并删除它,
有没有很好的简单方法呢?

我是一个jQuery选项,您可以找到所点击的require('nameOrPath')
的索引,并使用以下函数删除该元素:
<div>

我不是百分之百确定你要做什么或者其中一些是什么意思,但这是你想要做的事情吗?
var peopleTracker = {};
var peopleCounter = 0;
function addPerson()
{
// get the values
var firstName = document.getElementById("firstName").value.trim();
var lastName = document.getElementById("lastName").value.trim();
var birthday = document.getElementById("birthday").value.trim();
// make sure none are blank
if(firstName == "" || lastName == "" || birthday == "") return;
// give each person an ID so we can remove them later
var personID = ++peopleCounter;
peopleTracker[personID] = {
"firstName" : firstName,
"lastName" : lastName,
"birthday" : birthday
};
// add the person to the table
var row = document.getElementById("peopleList").insertRow();
row.insertCell().innerText = firstName;
row.insertCell().innerText = lastName;
row.insertCell().innerText = birthday;
row.insertCell().innerHTML = '<a href="#" onclick="removePerson(this.parentNode.parentNode, ' + personID + '); return false">remove</a>';
}
// delete a user from the tracker and remove the row
function removePerson(row, personID)
{
delete peopleTracker[personID];
row.parentNode.removeChild(row);
}

一些想法:
index
,因为当您从阵列中删除人员时,这会发生变化。答案 2 :(得分:0)
