javascript - Ionic - Check 2 radio buttons (different lists) by default -

-

i taking first steps in ionic, , trying create app.

in example, have 2 radio button lists (with options 1, 2, 3 , options 4, 5, 6):

enter image description here

i both radio buttons 2 , 4 checked default.

why radio button 4 checked?

what missing?

code below.

from model html:

<ion-view view-title="radio button demo">   <ion-header-bar align-title="left" class="bar-positive">     <h1 class="title">chosen option: {{item}}, {{item2}}</h1>    </ion-header-bar>    <ion-content> <ion-list>   <ion-radio ng-repeat="i in items" ng-value="i.id" ng-model="item.itemval" >{{i.name}}</ion-radio> </ion-list> <ion-list>   <ion-radio ng-repeat="i in items2" ng-value="i.id" ng-model="item2.itemval" >{{i.name}}</ion-radio> </ion-list>   </ion-content> </ion-view>

from controller javascript file:

.controller("mainctrl", function($scope) {   $scope.items = [     { id: 1, name: "test 1", value: "t1" },     { id: 2, name: "test 2", value: "t2" },     { id: 3, name: "test 3", value: "t3" }   ];    $scope.items2 = [     { id: 4, name: "test 4", value: "t4" },     { id: 5, name: "test 5", value: "t5" },     { id: 6, name: "test 6", value: "t6" }   ];    $scope.item = { itemval: "2" };   $scope.item2 = { itemval: "4" }; });

you need set name property on ion-radio denote belong different group.

make these changes in app.html make work:

<ion-view view-title="radio button demo">   <ion-header-bar align-title="left" class="bar-positive">     <h1 class="title">chosen option: {{item}}, {{item2}}</h1>   </ion-header-bar>     <ion-content>     <ion-list>       <ion-radio ng-repeat="i in items" ng-value="i.id" ng-model="item.itemval" name="group1">{{i.name}}</ion-radio>     </ion-list>     <ion-list>       <ion-radio ng-repeat="i in items2" ng-value="i.id" ng-model="item2.itemval" name="group2">{{i.name}}</ion-radio>     </ion-list>   </ion-content> </ion-view>

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 .
