Eri*_*ria 1 javascript gruntjs
我在自定义的grunt任务中遇到了错误.下面我发布了一个与问题相关的简单测试用例:
Gruntfile.js
module.exports = function( grunt ){
grunt.task.registerTask( 'endsWith', 'Test of string.prototype.endsWith', function(){
var value = grunt.option('value');
grunt.log.writeln( typeof value );
grunt.log.writeln( value.endsWith( 'bar' ) );
})
};

就像grunt无法识别String.proptotype.endsWith函数一样.这是正常的吗?
编辑:我正在使用节点v0.10.4
.endsWith是ES6功能,并未在Node.js v0.10.4中实现.
要使用.endsWith升级Node.js或添加polyfill:
String.prototype.endsWith = function(suffix) {
return this.indexOf(suffix, this.length - suffix.length) !== -1;
};
