Sightly jstl c:set analog

问题

On jsp I can write following code:

<c:set var="salary"  value="${object.salary}"/>

and then in code I can use ${salary} variable

Can you help to rewrite it using sightly?

P.S.

I tried this:

<div data-sly-use.salary="MySalary">
    <div data-sly-use.product="MyBean"  data-sly-unwrap>
        {
        <ul data-sly-list="${product.specifications}" data-sly-unwrap>
                "${item.sku ? item.sku : 'product'}" : "${item.label} ${item.value}"<div data-sly-test="${!itemList.last}" data-sly-unwrap>,</div>
        </ul>
        }
    </div>
</div>
<div data-bla-bla="${salary}"></div>

But I see compilation error

回答1:

You don't have the feature of assigning variables in Sightly. The maximum that is possible is comparing values, else all your logic goes into the Java or JavaScript Use-API classes.

When you are using data-sly-use, the value provided must either be

Java class that extends the WCMUse class or implements the Use interface or
JavaScript file that defines the use class.

Hence you receive a compilation error when the value of data-sly-use is neither of the above two.

However, I can suggest a workaround for your question, though I wouldn't recommend using the same. You can make use of data-sly-test and assign a variable name to that, which can later be used elsewhere.

For example.

<div data-sly-test.salary="MySalary"></div>
<div>
    <div data-sly-use.product="MyBean"  data-sly-unwrap>
        {
        <ul data-sly-list="${product.specifications}" data-sly-unwrap>
                "${item.sku ? item.sku : 'product'}" : "${item.label} ${item.value}"<div data-sly-test="${!itemList.last}" data-sly-unwrap>,</div>
        </ul>
        }
    </div>
</div>
<div data-bla-bla="${salary}"></div>
