How to solve Uncaught TypeError: Cannot read property 'length' of null

I have installed a wp plugin , When I use default wp theme , it works fine but when I use another theme it does not loads one of the tabs , by inspect element I get this
Uncaught TypeError: Cannot read property 'length' of null
The code on the page it is mentioning is this
function show_submissions(page,search)

Unable to cache ajax data on document.ready()

I am using following code to fetch and cache data from a ASP.NET handler. The problem is that whenever I cache data using a button click its working fine, but I want this to happen at document.ready() event. When I executed this code on document.ready() event, its fetching data perfectly, but its not getting data from the cache when I reload the page.
var localCache = {
data: {},
remove: function (url) {
delete localCache.data[url];
},
exist: function (url) {
return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
},
get: function (url) {
console.log('Getting in cache for url' + url);
return localCache.data[url];
},
set: function (url, cachedData, callback) {
cacheTime = (new Date()).getTime();
localCache.remove(url);
localCache.data[url] = cachedData;
if ($.isFunction(callback)) callback(cachedData);
}
};
var now;
var cacheTime;
var tDiff;
function getValueAtIndex(index) {
var str = window.location.href;
return str.split("/")[index];
}
//$(document).ready(function () {
$('#Button1').click(function (e) {
var url = '/Handlers/ResponseFetcher.ashx';
var topicid = "<%=desid %>";
$.ajax({
url: url,
type: "POST",
data:
JSON.stringify({ tid: topicid })
,
dataType: "json",
cache: true,
beforeSend: function () {
now = (new Date()).getTime();
if (localCache.exist(url)) {
tDiff = now - cacheTime;
if (tDiff < 20000) {
loadData(localCache.get(url));
return false;
}
}
return true;
},
complete: function (jqXHR, textStatus) {
localCache.set(url, jqXHR, loadData);
}
});
});
function loadData(data) {
console.log("now: " + now + ", cacheTime: " + cacheTime + ", tDiff:" + (cacheTime - now));
$('#responseloader').hide();
var resdata = JSON.parse(data.responseText);
$(resdata).each(function (i) {
$('#responsecontainer').append("<div>" + this.Title + "</div>");
});
}
Here tDiff will be undefined on first run. Is this the problem? or caching doesn't work if the page is reloaded? Please help!

says my function is undefined when assigning to a variable

i have a problem. I am trying to add a functions return value to a variable but it says the function is undefined. Here is my code. :
var selectedExpenseList = getSelectedExpenseIDs();
here is my function:

if ($(this)[0].id !== "checkAllExpenses") {
selectedExpensesList[i] = $(this)[0].id.split('_')[1];
++i;
}
});
return selectedExpensesList;
}

I noticed that your function code is tabbed once more than your code that calls it. It's possible that your function is scoped improperly (e.g. it's declared inside another function and you're calling it from outside that function).
If your function is coming back as undefined, it's almost certainly a scoping issue. I see nothing wrong with the function itself.
For instance:
$(document).ready(function () {
function myFunction() {
return 3;
}
});
var bob = myFunction(); //Error: myFunction is not defined.
