this article is about ajax and and using proxy server with apache httpd

I wanted to try get ajax data from other site..
and Chorme and WebBrowser told me that cross domain security so I can't access
this url...
there is good solution when you develope different site and test it

Jquery extend function

This is somehow good when extend data and overwrite

var object1 = { apple: 0, banana: { weight: 52, price: 100 },

maintaining position in list when history back

Recently I was ordered that I have to change paging list way to infinite list, that mean I have to query with special key, not page number.
I have to think seriously, can I do this???
I searched other homepages if there are hompages that use this pattern. Best homepage was Facebook to benchmark
Facebook show us topic in timeline and if scroll to bottom , ajax will get more data from the server.
but there are something that i should consider carefully.  what is that???
for example, i choose one topic and go backpage, list page will refresh and position I last saw will be lost. In other word, ajax loading data dosen't save homepage last state.
To solve this problem. I Think step.
1. in my list page, call list data from the server using ajax. 2. I scroll some position. 3. I click some data.   - I have to check scroll.x scroll.y and save in history. 4. detail page show 5. go back to list page 6. get the last scrollx, scroll.y from saved data     - ajax call againg 7. and scroll to las…

Element ready after appending data.

In jquery, there I can catch callback when data is fully loaded .
I wanted to knwo maybe in angularjs has too. I searched much time and find out how to use below is just example.

angular.element(document.querySelector('#contentBox')).append(data).ready(function(){ //                alert('ready complete'); $scope.loaded();
});

and 
angular.element i can use jquery lite  reference by

angular ng-if

how can I check if data is over number or like when in jstl
there i can use ng-if

for example .
