问题
So I want to put a variable through a filter inthe ng-bind directive
ng-bind="input | filter"
but I want to insert more text
ng-bind="input | filter + 'more' "
but this isn't working. Is there a way to add more text in ng-bind, like you could if you were simply using {{}}:
{{input | filter}} more
回答1:
Instead of interpolating(using {{}}) something in the ng-bind directive you can simply enclose the filtered value with a parenthesis and append your text.
<h1 ng-bind="(input | filter) + ' more stuff'"></h1>
furthermore, if the text you want to add is not in any way dynamic then I suggest you append another element to bind the filtered value and then add the text after that element.
e.g.
<h1><span ng-bind="(input | filter)"></span> more stuff</h1>
This saves you one concatenation process.

You can do something like this:
<h1 ng-bind="'{{input | filter}}' + ' more stuff'"></h1>
