javascript - website gets slow when huge amount of data is being loaded -

-

i have internal team website build using python django , angularjs. website works fine when there low data/ content on it. when website gets scrolled , more data loaded. becomes slow. major problem occurs when try open modal or try write text in textarea. text lags while writing , modal open slowly.

i have used nested ng-repeat there 5 nested ng-repeat.

<div ng-repeat="x in xyz">    <div ng-repeat="y in xyz">    </div>    <div ng-repeat="img in xyz">    </div>    <div ng-repeat="y in xyz">      <div ng-repeat="z in xyz">      </div>    </div>  </div>

above example of structure being used in website. above snippet repeat around 100 times thorughout page. these having images, forms, text, input , user tagging facebook. ngcachebuster,ui.bootstrap, ngtagsinput, ui.mention,monospaced.elastic these external library being used in website. website built using bootstrap. there specific reason why website becomes heavy. each size of image around 100kb on average.

really? page loads slow when there alot of data? :d

anyway simple method speed-up heavy data apps conditionally load , render parts of it, example:

<div ng-repeat="x in bla" ng-click="showl1 = true">     <div ng-repeat="y in boo" ng-if="showl1  === true">         //more...     </div> </div>

on other part double check architecture, since there limited amount of data person can take page , therefor start thinking tabs , paging

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
