JavaScript中字符串拼接的基本方法

非常简单，就用一个"+"将两个字符串"相加"：

rush:js;"> var longString = "One piece " + "plus one more piece.";

要将多个字符串累积为一个字符串，还可以使用"+="操作符：

rush:js;"> var result = "";

result += "My name is Anders"

result += " and my age is 25";

要在字符串中添加换行符，需要使用转义字符""：

<div class="jb51code">
<pre class="brush:js;">
var confirmString = "You did not enter a response to the last " +
"question.Submit form anyway?";

var confirmValue = confirm(confirmString);
