AngularJS ng-style with a conditional expression

Question

I am handling my issue like this   ng-style    width  getTheValue        But to avoid having this function on the controller side  I would much prefer to do something like this   ng-style    width  myObject value     ok     100      0        How can I do this

EDIT  Ok i was previously not aware that AngularJS usually refers to Angular v1 version and only Angular to Angular v2  This answer only applies for Angular Leaving this here for future reference    Not sure how it works for you guys but on Angular 9 i have to wrap ngStyle in brackets like this   ng-style   quot    width     myObject value     ok      100      0     quot   Otherwise it doesn t work

On a generic note  you can use a combination of ng-if and ng-style incorporate conditional changes with change in background image    lt span ng-if  selectedItem  item id                ng-style    background-image   url    images      item id      active png    background-size   52px 57px   padding-top   70px   background-repeat   no-repeat   background-position    center    gt  lt  span gt           lt span ng-if  selectedItem  item id                ng-style    background-image   url    images      item id      deactivated png    background-size   52px 57px   padding-top   70px   background-repeat   no-repeat   background-position    center    gt  lt  span gt

also this syntax for ternary operator will work     ng-style   lt  scope var gt  lt condition gt                lt css-prop-1 gt      lt value gt       lt value2 gt   100                 lt css-prop-2 gt     lt string gt                         lt css-prop-1 gt     lt string gt              lt css-prop-2 gt     lt string gt              where  lt value gt  are  scope property values  In example   ng-style  column histograms value  gt 0             width    column histograms value     column histograms limit  100            background    F03040               width   1px        background    2E92FA              this allows for some calculaton into the css property values

jfredsilva obviously has the simplest answer for the question      ng-style     width     myObject value     ok      100      0        However  you might really want to consider my answer for something more complex   Ternary-like example    lt p ng-style   width   true  100   false  0    myObject value     ok     gt  lt  p gt    Something more complex     lt p ng-style       color         blueish   blue   greenish   green    color        font-size     0   12px   1   18px   2   26px    zoom      gt Test lt  p gt    If  scope color     blueish   the color will be  blue    If  scope zoom    2  the font-size will be 26px    x000D   x000D  angular module  app       x000D  function MyCtrl  scope    x000D     scope color    blueish   x000D     scope zoom   2  x000D    x000D   lt script src  https   ajax googleapis com ajax libs angularjs 1 0 1 angular min js  gt  lt  script gt  x000D   lt div ng-app  app  ng-controller  MyCtrl  ng-style    x000D     color         blueish   blue   greenish   green    color     x000D     font-size     0   12px   1   18px   2   26px    zoom   x000D     gt  x000D    color     color   lt br gt  x000D    zoom     zoom   x000D   lt  div gt  x000D   x000D   x000D
