``` //假如这是我们获取到的数据 //返回的有可能是数组,我们就要用到 for in 或 for 遍历出来 //单独的一个object var myData = { "id":"123456789", "name":"pengyaping", "tel":"137-8888-8888", "Email":"364154405@qq.com" } var aaa = '<div>' + '[name]' + '</div>' //[name]替换成我们返回的对象里面的内容 aaa.replace(/name/g, myData.name) //document.write(aaa.replace(/name/g, myData.name)) $("#center").html(aaa.replace(/name/g, myData.name)); //多个字段替换 .replace().replace(); //str.replace(/name/g,myData.name).replace(/tel/g,'你好'); ```
