es6 模板字符串

模板字符串 提供构造字符串的语法糖，在 Prel/python 等语言中也都有类似特性。

1、反引号模板，可以换行

2、反引号模板，可以嵌套

用+``来嵌套

好处：语法更加简洁

        var name="123456一堆返回的数据"
        var desc="title内容";
        var tpl=`
        <div>
            <span>${name}</span>
        </div>
        `;
        console.log(tpl);
        /*<div>
        <span>123456一堆返回的数据</span>
        </div>*/
        var tpl2=`
        <div>
        <span>${name +`<strong>${desc}</strong>`}</span>
        </div>
        `;
        console.log(tpl2);
        /*<div>
         <span>123456一堆返回的数据<strong>title内容</strong></span>
         </div>*/

其它例子

// Basic literal string creation
`This is a pretty little template string.`

// Multiline strings
`In ES5 this is
 not legal.`

// Interpolate variable bindings
var name = "Bob", time = "today";
`Hello ${name}, how are you ${time}?`

// Unescaped template strings
String.raw`In ES5 "\n" is a line-feed.`

// Construct an HTTP request prefix is used to interpret the replacements and construction
GET`http://foo.org/bar?a=${a}&b=${b}
    Content-Type: application/json
    X-Credentials: ${credentials}
    { "foo": ${foo},
      "bar": ${bar}}`(myOnReadyStateChangeHandler);
