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




changed apache conf.htttp ~!!!

Jquery extend function

This is somehow good when extend data and overwrite

var object1 = {



  apple: 0,



  banana: { weight: 52, price: 100 },



  cherry: 97



};



var object2 = {



  banana: { price: 200 },



  durian: 100



};



 



// Merge object2 into object1



$.extend( object1, object2 );
object1 data
{"apple":0,"banana":{"price":200},"cherry":97,"durian":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 last position.

this is what I think

I might be good to change what I'm now working on.

Test Script

1. History.js

2. Iscroll4 

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 .


referenced by https://code.angularjs.org/1.1.5/docs/api/ng.directive:ngIf

1. <span ng-if="checked" ng-animate="'example'">
2. I'm removed when the checkbox is unchecked.
3. </span>
