输入框帮助JavaScript / HTML

Question

MAJOR EDIT: Okay, so I am have to create a HTML page like this . I have already done the HTML work but I need help in the Javascript section. SO there are 2 parts of this - first to create additional textboxes when + is clicked, which I have already done

 textBoxNum = 2 function addElement() { if (textBoxNum => 2) { textBoxNum++; var objNewDiv = document.createElement('P'); objNewDiv.innerHTML = '<input type="text" placeholder = "Option ' + textBoxNum + '" id = "option' + textBoxNum + '" />'; document.getElementById('content').appendChild(objNewDiv); }; ;} 

The second part is to get information from the input boxes and save them into local storage in a variable, how do i do that considering the user could have clicked + and add more input boxes

Actually you can't set the Name of variable in that way, instead you can
1) create an array options = [], and keep use options[x]
2) create inputs with certain class (for example class="option") and use
var options = document.getElementsByClassName("option");
which returns an array
3) create inputs with certain name(for example name="option") and use
var options = document.getElementsByName("option");
which returns an array
4) get an array of all inputs on the page
var options = document.getElementsByTagName('input');
