JavaScript报错--未结束的字符串常量
今天在js中处理一个后台request传的值时,本来为了图省事,直接在js中使用EL表达式,一个成功了,另一个却老是报错:“未结束的字符串常量”!!!

最后发现,原来那个报错的EL表达式中传过去的值中有个中文的句号,导致了老是换行.........
function initpage(){
var str1 = "${periodTypeValue}";
var str2 = "${premiumValue}";
if(str1 != "" ||str2 != ""){
document.getElementById("showDesc").style.display = "";
document.getElementById("periodDesc").innerHTML = str1;
document.getElementById("premiumDesc").innerHTML = str2;
}
}
=============================================
最后经查资料,发现其他网友也有遇到过,是有隐藏域的形式解决的,即:不直接将该数据以参数形式传递,而是先将其赋值在一个隐藏的文本内,需要调用的函数里只需读取该文本里的内容即可.
意外发现后台Action中传过来一个null值是,这样显示的竟不是null,而是“”
var str1 = document.getElementById("periodTypeValue").value;
var str2 = document.getElementById("premiumValue").value;
