ngMocks.findTemplateRefs
Returns an array of all found TemplateRef
which belong to the current element and all its children.
If the element is not specified, then the current fixture is used.
ngMocks.findTemplateRefs( fixture?, directive )
ngMocks.findTemplateRefs( debugElement?, id )
ngMocks.findTemplateRefs( debugElement?, [attribute, value?] )
or simply with selectors which are supported by ngMocks.find
.
ngMocks.findTemplateRefs( cssSelector?, [attribute, value?] )
Assume, that a template has the next code.
<ng-template myTpl="header"></ng-template>
<ng-template myTpl="footer"></ng-template>
Then, we can find ng-template
like that:
// returns 2 elements
const allByDirective = ngMocks.findTemplateRefs(MyTplDirective);
// returns 2 elements
const allByAttribute = ngMocks.findTemplateRefs(['myTpl']);
// returns 1 element
const onlyHeaders = ngMocks.findTemplateRefs(['myTpl', 'header']);
// returns 1 element
const onlyFooters = ngMocks.findTemplateRefs(['myTpl', 'footer']);
// returns 0 elements
const empty = ngMocks.findTemplateRefs(['myTpl', 'body']);
