js原生实现一个简单的模版引擎

• 代码如下
  var template = "

  Name: {{name}}
  Company：{{company}}

  City：{{city}}

  ",
  me = {
  name: "sdcV",
  email: "[email protected]",
  company: "Microsoft",
  city: "London"
  };
  function applyDataToTemplate(templateString, dataObject) {
  var key, value, regex;
  for(key in dataObject){
  regex = new RegExp("{{" + key + "}}", "g");
  value = dataObject[key];

         templateString = templateString.replace(regex, value);
     }
      return templateString;
  }
  alert(applyDataToTemplate(template, me));
