angular.module(‘ng‘).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 lastspace = value.lastIndexOf(‘ ‘);
if (lastspace != -1) {
value = value.substr(0, lastspace);
}
}
return value + (tail || ‘ …‘);
};
});
Usage:
{{some_text | cut:true:100:‘ ...‘}}
Options:
- wordwise (boolean) - if true, cut only by words bounds,
- max (integer) - max length of the text, cut to this number of chars,
- tail (string, default: ‘ …‘) - add this string to the input string if the string was cut.
