Angular js - 返回一个包含HTML字符的字符串

Question

I made a filter just to add an antislash after a value if another given value is not empty and I would like to separate this antislash from the rest of the string with   . Actually the filter itself work but right the string " " as is in the page.

angular.module('ngMod', []).
filter('antislash', function() {
  return function(input) {
    if( input==null || input.length === 0 ){
      return null;
    }else{  
      return ' / '; 
    }
  }
});

It displays in the page :  / 

Does exist an html filter or something equivalent ?

Answer 1

It works by giving the unicode value for   .

angular.module('ngMod', []).
filter('antislash', function() {
  return function(input) {
    if( input==null || input.length === 0 ){
      return null;
    }else{  
      return '\u00A0/\u00A0'; 
    }
  }
});

You can also use $sanitize with ng-bind-html and ng-bind-html-unsafe to output html snipets.
