How to declare, initialize and use a variable using SIGHTLY

[Dinu_Arya]

Hi,

I have a requirement which needs a counter integer variable to be incremented in loop or a flag variable to be set to 0/1 or true/false. I've to show 1st item using some UI and the rest of the items with another UI. How can I achieve using sightly? I have referred tutorials but no where mentioned how to create a variable in sightly as <c:set var="variableName" value="variableValue"/> in JSTL. Please help me in this.

Thanks,

Arya.

You can do that like this...

<div data-sly-test.yourName="${currentPage.name}" data-sly-unwrap></div>

Now you do things like

<div data-sly-test="${yourName}">....${yourName}</div>

Hi Feike,

Not sure if this is how it is supposed to work. If it is, how do I get my code working?

I have a requirement as below:

<div d-automode="${obj.message}"> <p>Content goes here</> </div>

The value of ${obj.message} is either 'true' or 'false'. But, when the value is false, sightly completely removes the attribute 'd-automode' and the resulting HTML is as below:

<div> <p>Content goes here</> </div>

How do I set value of 'false' in this attribute?

Cheers,

ashtrick

Hi Feike,

Thanks. It worked for me. For setting purpose this is ok. But we can't increment a variable in sightly. Also we can't check whether an object is null or not. I tried to check whether the object is null or not. But I got errors. Adobe has to provide these features. I think some background work is going on to implement these features. We can follow this for time being. I hope soon they will answer all these questions/issues related to Sightly.

Thanks,

Dinakar.

1. try this:
2.  
3. <div d-automode="${obj.message ? 'true' : 'false'}">
4. <p>Content goes here</>
5. </div>

hi,

Give me your example, where you get these errors.

Indeed you can't increment a counter, you should use a use-class for that.

Checking for null can be done like data-sly-test="${objectToBeChecked}

Hi Feike,

I tested like this ->  data-sly-test="${objectToBeChecked != null}"

I got errors.

Thanks,

Arya.

Already tried, no luck 

[Feike_Visser1]

just use this data-sly-test="${objectToBeChecked}" or data-sly-test="${!objectToBeChecked}".

cheers,

<div data-sly-test.message="${'false'}"></div>

${message}

<div d-automode="${message ? 'true' : ' false '}">

    <p>Content goes here</>

</div>

Thanks Feike.
