javascript - Javascript结合两个字符串总是在空格后取出字符串？

Question

我只是尝试组合两个字符串，例如：

var temp = "<meta property='og:title'  content="; temp += "work1 work2"; temp += "/>";

document.write(temp);

但结果总是：

<meta property='og:title'  content=work1 />

但应该是：

<meta property='og:title'  content=work1 work2 />

我是 javascript 新手，不胜感激，谢谢:-)

为范围内容属性值添加单引号：

var temp = "<meta property='og:title'  content='"; temp += "work1 work2"; temp += "' />";

document.write(temp);
