TypeError:Handlebars.registerHelper不是函数 [英] TypeError: Handlebars.registerHelper is not a function

问题描述

截至两天前，我对节点和车把是全新的，所以请多多包涵. 我正在尝试使用自定义车把帮手，但不完全确定将其放置在何处.

I am brand new to node and handlebars as of two days ago so bear with me. I am trying to use custom handlebars helpers but am not entirely sure where to put it.

我不断收到"TypeError:Handlebars.registerHelper不是函数"

I keep getting "TypeError: Handlebars.registerHelper is not a function"

现在，我将其保存在server.js文件中.不确定这是否正确.

Right now I have it in my server.js file. Not sure if this is correct.

var express  = require('express');
var app      = express();
var Handlebars  = require('express-handlebars');


app.engine('handlebars', Handlebars({
    defaultLayout: 'main'
}));

app.set('view engine', 'handlebars');

Handlebars.registerHelper("if", function(conditional, options) {
  if (options.hash.desired === options.hash.type) {
    options.fn(this);
  } else {
    options.inverse(this);
  }
});

推荐答案

根据此处找到的文档，您似乎需要像这样使用它:

It looks like you need to use it like this, according to the docs found here: https://github.com/ericf/express-handlebars

var hbs = Handlebars.create({
  // Specify helpers which are only registered on this instance.
  helpers: {
    foo: function () { return 'FOO!'; },
    bar: function () { return 'BAR!'; }
  }
});
