这里面有一个全角的”下双引号，修改Script为：
function buttonreport(buttonId,buttonName,buttonValue) {
var userMessage1="button id:"+buttonId+"\n";
var userMessage2="button name:"+buttonName+"\n";
var userMessage3="button value:"+buttonValue+"\n";
alert(userMessage1+userMessage2+userMessage3);
}即可（在button name右边）
追问
想问一下你这里JavaScript用的是什么开发软件，我是写的文档，很麻烦。

var userMessage2="button name:”+buttonName+"\n";// "button name:”闭合引号是中文的。改为英文的引号就好了
