Javascript组合两个字符串总是去掉空格后的字符串？

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，感谢任何帮助，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);
