I am using sessionStorage to get some data and able to use it to create a link and append it to the page.
(function() {
var rep_info = document.getElementById('rep-info'),
session = sessionStorage.getItem('ngStorage-getRepInfo'),
obj = JSON.parse(session),
vanity_name = obj.profile.data.vanityName,
your_URL = 'https://foo.com/';
console.log(obj.profile.data.vanityName);
rep_info.insertAdjacentHTML('afterbegin', 'foo.com/' + vanity_name + '');
})();
However if I copy and paste the URL of the page which contains the script above, it doesn't fire. Instead I get this error.
Uncaught TypeError: Cannot read property 'profile' of null
But when I do a refresh, the script fires.
I should mention this page/site is accessed via user authentification i.e. username & password.
I found this solution, but I couldn't figure out how to get it going.
Thanks in advance!

I included the library I referenced and my attempt at using to solve my problem, it's right after the module.

I have a filter script that ads a value to my url trough a set of checkboxes. Each checkbox group can only ad one value.
First click on a checkboxgroup looks like this:
/Network-CAT-cables?fss=yellow
Where the fss=yellow is the added parameter. A click on another chekcbox group would look like this:
/Network-CAT-cables?fss=yellow+cat6
If I check another checkbox in one of the above groups it replaces the previous value.
Now i need to add a parameter that looks like this:
&sps=d211av450240_2.0
If I set that as a value in the checkbox it kinda work. It ads the parameter and sort after it. And if i add a "normal" value it places before it. and that works too - like this:
?fss=yellow+cat5&sps=d211av450240_2.0
The problem is that when I have several of the new custom parameter in a group. In the other checkbox groups I can only have one value - and the chosen one replaces the old parameter. with the custom parameter I want to add it just ads on, instead of replaceing - like this.
?fss=yellow+cat5&sps=d211av450240_2.0+&sps=d211av450240_1.0
The correct outcome would have been
?fss=yellow+cat5&sps=d211av450240_1.0
I know this is because of the "&" in the parameter - but unsure how to work it out. I cant change the parameter either - and I know checkboxes are ment to be for multiple choices, but its like this for a reason.

I'm not an Angular guru, but couldn't you just move the functions to achieve a factory-like pattern? I have not tested this, but with about two minutes of copy-n-paste...

I am trying to create tree like component,
for the first level data is coming from the server ,
if the user clicks the node i need to populate the child nodes with the data from service call.
what is the best way to save the data for this tree component ?
because user will do some operations on the tree component like remove, add & move. Finally i need to send the updated data to the server .
This is the hashmap functionality I use in javascript.
I based it off the docs of java 7 hashmap.
http://docs.oracle.com/javase/7/docs/api/java/util/HashMap.html
I added the load and save variables to allow JSON storage. be careful though. if you stored any complex objects(like a hashmap in a hashmap) you will lose that.
You'd have to implement your own object instantiatiors in the load and save function.
A JSfiddle to play with if you like:
