'increment variable value in spark view engine
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
Solution 1:[1]
The best way to do this is to use the built in indexer that Spark creates in a for loop. The above could be written like this:
<div each="var item in Model">
<input name='field-${itemIndex}' value='${item.Id}'/>
</div>
Even shorter than the original, and no need to track variables yourself. Also, no need to specifically use item
, in your case it would be xIndex
because x
was your instance.

With slight modification:
<var i="0"/>
<div each="var x in Model">
<input name='field-${i}' value='${x.Id}'/>
<set i="i+1" />
</div>
this should work.
The initial 'set' has been changed to 'var' and quotes were added around i+1.
