PURE Errors
If a PURE method encounters a situation that it cannot handle
it throws an error describing the problem. The following is a list of
the errors PURE can throw. You can catch these errors by putting your
method calls in a try{…} catch(e){…}
block.
The template <selector> was not found
No element in your web page matches the selector you supplied. Check the selector syntax above, and the class or id of the item you are trying to select.
The root of the template is undefined, check your selector
bad loop spec: <selector>:<loop specification>
"item<-..." is a reserved word for the current running iteration. Please choose another name for your loop.
bad selector syntax: <selector>
Your selector must be well formed. See the reference above for details of well formed selectors
The node <selector> was not found in the template:<template>
You have tried to name a place in your template which is not there. Possible reasons
-
You misstyped the selector
-
The selector is outside the selected template
-
The wrong template was selected
append/prepend cannot take place at the same time
You specified an action to extract a value from the data and both prepend and append it to the current content of the selected element. i.e. you had a link specifier like this
“<selector>”:”+<dataname>+”
That is not allowed. Try “selector”:”+dataname”, “selector”:”dataname+” if you really want to do this.
no append/prepend/replace modifiers allowed for loop target
Not sure what this means
cannot append with loop (sel: <selector>)
Not sure what this means
The template root, can't be looped.
You specified a loop item as your entire template. e.g. <li class=iterated></li> and then selected ‘iterated’ as your template. Try
<ol
id=myloop>
<li
class=iterated></li>
</ol>
and specify ‘myloop’ as your template.
sort is only available on arrays, not objects
JSON objects are defined as ‘unordered’, i.e. the order of the items is unpredictable. So sorting is not an option. Try to organise your data into an array ( […]) if you want to sort it.
cannot have more than one loop on a target
You have tried to loop over two separate arrays on the same target. You cannot do this. Instead, create a second target for the second loop. e.g.
<li
class=loop1><li>
<li
class=loop2><li>
Error in the selector: <selector> A directive action must be a string, a function or a loop(←)
You specified an <action> that was not a string (accessing a value in your data by its property name), a (lambda) function, or an object containing a loop specification. Check the <action> of the <selector> specified for typos etc.
