Declare variables locally
- The `allSections` variable was leaking into the global scope, due to a
typo in the declaration.
- `dataProcessed` can be declared more narrowly within the callback.
to successfully call a function with parameters by setTimeout,
it needs to be a function that will be called by setTimeout internally.
this patch actually enables multiple tries for calling the setState function.
Change the `MathJax.Hub.Queue(initializeRequest)` to a simpler function call
(`initializeRequest.call(this)`). This was failing to give a proper context
to initializeRequest, and `this.value` was turning up as `undefined`.
Also add a fallback if we need to display some code before MathJax finishes
its original typesetting.
I was stubbing out `Queue` in my specs, so the tests had to be changed around
a little.
Named `FormulaEquationInput` (name up for debate)
- Based off ChemEqnIn
- Add FormulaEquationInput in inputtypes.py
- Add a call to a skeleton method for a preview
javascript:
- Queue up some MathJax
- Put some ordering on the AJAX requests: add a parameter when the request was started, when it returns check that it isn't outdated before displaying the preview
- Tests
Note: we moved the `jsinput` tests and DISABLED them, because they were causing the tests to fail.
