Angular.js filter to reduce a word to the last space and add a '...' at the end

ReduceWord.js

app.filter('cut', function(){
        return function(value, wordwise, max, tail){
            if(!value)
                return ' ';

            max = parseInt(max, 10);

            if(!max)
                return value;
            if(value.length <= max)
                return value;

            value = value.substr(0, max);
            if(wordwise){

                var indexs = [];

                for(var i = 0; i < value.length; i++){
                    if(value[i].indexOf(' ') != -1){
                        indexs.push(i);
                    }
                }

                var lastspace = indexs[indexs.length - 1];

                console.log(value, indexs);

                if(lastspace != -1){
                    value = value.substr(0, lastspace);
                }
            }

            return value + (tail || ' ...');
        };
    });

To use it in the view {{ word | cut:true:30:' ...'}}

When:

• value: is the word you want to cut.
• wordwise: if it's true you reduce the word.
• max: max length you want to show.
• tail: by default is ' ...' but you can use what you want.
