Javascript未捕获语法错误：意外令牌。 对于array.length

Question

I am extremely new to programming and an assignment from class was to create a voting website. I was able to create variables and put them into local storage, as such:

var eventName = document.getElementById("eventName").value;
document.getElementById("p1").innerHTML = (eventName);
localStorage.setItem("eventName", eventName)
localStorage.getItem("eventName")

Now, we were supposed to include all of this into an array so that we can get multiple eventNames. My teacher is never really clear with his instructions, so this is what I got now:

var eventName = [];
var index ;

function submitNewEvent() {

eventName[index] = document.getElementById("eventName").value;
index = index + 1;
var eventNmString = JSON.stringify (eventName);
localStorage.setItem("eventName", JSON.stringify (eventName));
localStorage.getItem("eventName")
array = JSON.parse(localStorage.getItem("eventName"));

array = parse;
var output = "";
for (var i=0, array.length > i; i++){
output += "<p>"+array[i];
}
document.getElementById("p1").innerHTML = (output);

I would really appreciate any help if anyone can explain to me what I did wrong.

Here's the syntax error (the error message should point to that line as well):

for (var i=0, array.length > i; i++){
//          ^

The array.length expression is not a valid identifier name, like i is (in a statement like var i=0, array=5; or so). You wanted to use a semicolon there:

for (var i=0; i < array.length; i++){
//          ^
