iframe - What happens when removing an object used by a ngRepeat in AngularJS? -

-

edit: jsfiddle example here.

i have ngrepeat spawns directives containing iframes. 

div(ng-repeat='element in elements')     ng-switch(on="element.type")          a-directive(ng-switch-when="something")         another-directive(ng-switch-when="somethingelse")

now, inside directive loading content iframe after event, doing:

$iframe[0].contentwindow.d_contents = "html" $iframe[0].src = 'javascript:window["d_contents"]'

everything works nicely.

when remove 1 of these elements model (in controller) like:

elements.remove(object) //using sugarjs, that's not issue, same behaviour splice

the ui gets updated accordingly, i.e. element disappear.

the problem

this works expected: 

elements.push(ele1) elements.push(ele2)  .. init iframes inside ele1 , ele2 content ..  elements.remove(ele2)

result: ele2 disappears ui, ele1 still there iframe loaded

this not:

elements.push(ele1) elements.push(ele2)  .. init iframes inside ele1 , ele2 content ..  elements.remove(ele1)

result: ele1 disappears ui, ele2 still there iframe, iframe content empty, , iframe.load() gets fired.

what happening here? why iframe getting reseted?

you need add loading logic inside load() reload content when dom changes.

var linkfn = function (scope, element, attrs) {     init(function () {         var $iframe = element.find("iframe")          var refresh = function () {             var doc = $iframe[0].contentwindow.document;             doc.open();             doc.write(scope.ele.source);             doc.close();         }          $iframe.load(function () {             console.log(scope.ele.id + ": loaded ");              //refreshing             refresh();         });          //initial loading         refresh()     }) }

you need use doc.write() scenario or recursive loop error.

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
