如何将字符串{}值替换为obj(键值) [英] How to replace string {} value to obj (key value)

问题描述

我最近开始在nodeJs上编程.

I recently started programming on nodeJs.

我有不同的字符串和Json对象；

I have different strings and Json Object;

例如:

var str = 'My name is {name} and my age is {age}.';
var obj = {name : 'xyz' , age: 24};


var str = 'I live in {city} and my phone number is {number}.';
var obj = {city: 'abc' , number : '45672778282'};

该如何自动执行此过程，因此我将使用字符串和obj将字符串{}值替换为obj(键值).

How do I automate this process, so using string and obj I will replace string {} value to obj (key value).

我尝试了PUG，但无法解析.

I have tried PUG but not able to parse.

pug.render(str, obj);

对我不起作用.

推荐答案

让我们看到，您想要制作类似于模板的东西，就像把手 http://handlebarsjs.com/.

lets see, you want to make something like templating, just like handlebars http://handlebarsjs.com/.

我将为您提供一个为您制作简单把手的示例:

I will give you this example to make a simple-handlebars for you case:

function render(template, properties)
{
     var result = template;
     for (i in properties)
     {
         result = result.replace("{"+i+"}",properties[i]);
     }
     return result;
}

但是，这只会更改各个属性的首次出现，如果您愿意，可以使用它来替换整个模板中的所有属性:

but this one will only change first occurence of respective properties, if you want you may use this for replace all in the whole template:

function render(template, properties)
{
     var result = template;
     for (i in properties)
     {
         var reg = new RegExp("{"+i+"}","g");
         result = result.replace(reg,properties[i]);
     }
     return result;
}
