Question

I am having an issue with using Spring’s mechanism to fill in an array of strings if one of the strings contain a new line.

The jsp code looks like this:

function foo() {
    var strs = new Array();
    <c:forEach items"${strItems}" var="s">
        strs.push("${s}");
    </c:forEach>
}

After being rendered for the client, the javascript becomes:

function foo() {
    var strs = new Array();
        strs.push("item1");
        strs.push("item2
with
newlines
in it.");
        strs.push("item3");
}

Which is now invalid javascript. I need to keep the endlines in the string, so I cannot scrub the data of them. I am unsure of what to do, any suggestions would be a big help.

Thanks.

There are libs to do the type conversion:

• json-simple
• gson

And all you have to do is to let them serialize your array, and output the result as a string.
