$scope.delete = function(){              here want t.number          };          
<li class="item" ng-repeat="t in items">                    <div class="row">                        <div class="col col-10"><i></i></div>                        <div class="col col-70">                            <span class="number">{{t.number}}</span>                            <p class="date">{{t.date}}</p>                        </div>                        <div class="col col-20">                            <i class="ion ion-ios-paper" ng-click="details()"></i>                            <i class="ion ion-trash-a" ng-click="delete()"></i>                        </div>                    </div>                </li>

please guide me how access html elements in angular js controllers.

here need in ng-click="delete(items, $index)'

<li class="item" ng-repeat="t in items">     <div class="row">         <div class="col col-10"><i></i></div>         <div class="col col-70">             <span class="number">{{t.number}}</span>             <p class="date">{{t.date}}</p>         </div>         <div class="col col-20">             <i class="ion ion-ios-paper" ng-click="details()"></i>             <i class="ion ion-trash-a" ng-click="delete(items, $index)"></i>         </div>     </div> </li>

then, in controller:

$scope.delete = function(array, index){     console.log('item number: ',index); // element number     array.splice(index, 1); // delete element };

and explain it, in ng-click, send array name items in case , index (location in array), delete function get's array want delete , position of item in array

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
