javascript - 名字 中间名 javascript

Question

在 Javascript 中，我尝试将全名(名字、中间名和姓氏)输入到字段中，单击提交按钮后将输出到三个单独的字段:字符长度、中间名和 3缩写。到目前为止，我已经到达字符字段，但我对如何获取两个空格之间的信息感到困惑。

// strings.js
// This script takes a name and spits out its character length with initials.

// Function called when the form is submitted.
// Function performs the calculation and returns false.
function formatNames() {
'use strict';

// For storing the Full Name, Middle name, initials, length:
var lengthName;
var middleName;
var yourInitials;


// Get a reference to the form values:
var fullName = document.getElementById('fullName').value;

// Perform the character spit out:
lengthName = fullName.length;

// Pull out the middle name:

// Display the volume:
document.getElementById('nameLength').value = lengthName;

// Return false to prevent submission:
return false;

} // End of formatNames() function.

// Function called when the window has been loaded.
// Function needs to add an event listener to the form.
function init() {
'use strict';
document.getElementById('theForm').onsubmit = formatNames;
} // End of init() function.
window.onload = init;

这听起来像是家庭作业，所以我会在不破坏学习体验的情况下给您一些提示。

您可以使用split(' ')在字符串上获取该字符串中的单词数组(用空格分隔)。

您可以使用charAt(0)在字符串上获取字符串的第一个字母。
