如何在角度表达式中数字等于0时显示空字符串

Question

<div>{{a.value | number:0}}</div>

this is what I have. I would like to display just "" if the value is 0. Anyway I can do that within the same line? or I have to filter it out in a controller.

Thanks

Answer 1

Pretty ugly but you can do it like this:

<div>{{a.value ? (a.value | number:0) : '' }}</div>

Not sure if there is more clearer way though.

Answer 2

Use ng-bind and ng-if . Like this:

<span ng-bind="a.value" ng-if="a.value"></span>
