运行时模板字符串

var templateString = (template, values) => {
    let output = template;
    Object.keys(values)
        .forEach(key => {
        output = output.replace(new RegExp('\\$' + `{${key}}`, 'g'), values[key]);
    });
    return output;
};

Test

console.debug(templateString('hello ${word} world', {word: 'wonderful'}));

如果你正在寻找一些相当简单的东西(只是固定的变量字段，没有计算，条件…)，但这也适用于没有模板字符串支持的浏览器客户端，如IE 8,9,10,11…

开始吧:

fillTemplate = function (templateString, templateVars) {
    var parsed = templateString;
    Object.keys(templateVars).forEach(
        (key) => {
            const value = templateVars[key]
            parsed = parsed.replace('${'+key+'}',value)
        }
    )
    return parsed
}

可能最干净的方法是使用箭头函数(因为在这一点上，我们已经在使用ES6)

var reusable = () => `This ${object} was created by ${creator}`;

var object = "template string", creator = "a function";
console.log (reusable()); // "This template string was created by a function"

object = "example", creator = "me";
console.log (reusable()); // "This example was created by me"

.．.对于带标签的模板字面量:

reusable = () => myTag`The ${noun} go ${verb} and `;

var noun = "wheels on the bus", verb = "round";
var myTag = function (strings, noun, verb) {
    return strings[0] + noun + strings[1] + verb + strings[2] + verb;
};
console.log (reusable()); // "The wheels on the bus go round and round"

noun = "racecars", verb = "fast";
myTag = function (strings, noun, verb) {
    return strings[0] + noun + strings[1] + verb;
};
console.log (reusable()); // "The racecars go fast"

这也避免了eval()或Function()的使用，这可能会导致编译器出现问题，并导致大量的放缓。

这是我最好的尝试:

var s = (item, price) => {return `item: ${item}, price: $${price}`}
s('pants', 10) // 'item: pants, price: $10'
s('shirts', 15) // 'item: shirts, price: $15'

generalify:

var s = (<variable names you want>) => {return `<template with those variables>`}

如果你没有运行E6，你也可以这样做:

var s = function(<variable names you want>){return `<template with those variables>`}

这似乎比前面的回答更简洁一些。

const fillTemplate =(模板，值)=> { 模板= template.replace (/(?<=\${)\ w + (? =}) / g, v = >“。”+ v); 返回功能。应用(这个,””、“返回”模板“+ +”;“])打电话给(值); }; console.log(fillTemplate("The man ${man}是${brother}的兄弟"，{man: "John"，兄弟:"Peter"})); //约翰是彼得的兄弟

感谢@Quentin-Engles的出色想法和最佳答案，让我开始了!

但是我将新函数直接存储在一个变量中，而不是每次都返回函数，这样函数和模板文字都只构建一次，而不是每次调用它，就像在Quentin的回答中那样。

const templateString = "Hello ${this.name}.";
var myData = {
    name: "world"    
};

const buildItem = new Function("return `" + templateString + "`;");

console.log(buildItem.call(myData));  // Hello world.

myData.name = "Joe";
console.log(buildItem.call(myData));  // Hello Joe.
