Javascript 非法令牌错误 [英] Javascript Illegal Token Error

问题描述

请原谅我，如果这是一个简单的问题，但我似乎无法找到此代码的原因:

Forgive me if this is a simple problem but I can't seem to find why this code:

function create_content(c)
        {
            var html = "<div id='header'>"+c+"</div>";
            if(c == "links")
            {
                var ul = "<ul><li><a href='http://www.mylink.com'>My Link 1</a></li>
<li><a href='http://www.mylink2.co.uk'>My Link 2</a></li></ul>";
                html = html + ul;
            }
            return(html);
        }

在 Chrome (win) 中给我这个错误:

Is giving me this error in Chrome (win):

未捕获的语法错误:意外令牌非法

Uncaught SyntaxError: Unexpected token ILLEGAL

在以var ul ="开头的行

On the line that starts with "var ul = "

任何建议都会有所帮助，谢谢！

Any advice would help thanks!

推荐答案

您正在 ul 字符串中插入一个换行符，在结束的 </li> 之间和开头

.JavaScript 字符串文字本身不能像这样跨越多行，除非你

You are inserting a line break in your ul string, between the closing </li> and the opening <li>. JavaScript string literals cannot span multiple lines like this by themselves, unless you

• 在除最后一行之外的每一行都添加一个 \(正如 Ivo Wetzel 所说):

• Trail a \ at each line but the last (as Ivo Wetzel says):

var ul = "<ul><li><a href='http://www.mylink.com'>My Link 1</a></li>\
<li><a href='http://www.mylink2.co.uk'>My Link 2</a></li></ul>";

将它们分开并连接起来，如下所示:

Break them and concatenate the parts, like this:

var ul = "<ul><li><a href='http://www.mylink.com'>My Link 1</a></li>";
ul += "<li><a href='http://www.mylink2.co.uk'>My Link 2</a></li></ul>";

(为了保持换行符，你需要在某处放置一个 \n ，但在 HTML 中这无关紧要.)

(To keep the newline there you would place a \n somewhere, but in HTML it won't matter.)
