带有回车和换行符的javascript错误

我在Java中有以下字符串：

"this is text1'r'nthis is text2'r'nthis is text3"

我将'r'n替换为<br/>，如下所示：

String temp = "this is  text1'r'nthis is text2'r'nthis is text3"
temp = temp.replaceAll("['r'n]+", "<br/>");

生成以下字符串："is text1 this is text2 this is text3"

现在，我想把它发送到JavaScript元素，如下所示：

var desc_str = "<%=temp%>";
document.getElementById('proc_desc').value = desc_str;

Java的输出很好，但在传递到HTML元素后，我收到了JavaScript错误"unterminated String literal"，我找不到线索，请帮忙。
