increment variable value in spark view engine

[nickname]

I try to go through a for each loop and increment value of variable to
name my label with below code

<set i="0"/>
<div each="var x in Model">

<input name='field-${i}' value='${x.Id}'/>

<set i=i+1 />
</div>
but it did not increment the value of 'i' , how can I increment the
value of i in above loop

thanks

maybe it's not parsing the attribute correctly? try adding quotes around it.

<set i='i+1' />

Another thing to consider is using one of the iterator autovariables to know what the index is. Just add the suffix Index to the iterating var, like:

<div each="var x in Model">

<input name='field-${xIndex}' value='${x.Id}'/>
</div>

You can also do i++. Always works for me

<set i="0"/> 
<div each="var x in Model"> 

<input name='field-${i++}' value='${x.Id}'/> 

</div>
