eval

问题 i have eval function, which needs to execute javascript from php. but i need to pass element, so i can put mouse over tips on the link user clicked on. var globalEval = function globalEval(src, element) { if (window.execScript) { window.execScript(src); return; } var fn = function(element) { window.eval.call(window,src); }; fn(element); }; im using following way to pass $(this) element globalEval(js_code, $(this)); // js_code is = alert(element); i get error of undefined element, which is

问题 I have an elaborate plot routine that generates box plots with additional layers of scatter and adds them to a plot list. The routine generates correct plots if they are created during the for loop directly via print(current_plot_complete) . However, if they are added to a plot list during the for loop which is printed only at the end, then the plots are incorrect: the final indices are used to generate all plots (instead of the current index at the time the plot is generated). This seems to

问题 I have a string input file as below (one equation per line): 1.0 - x[0] - x[1] x[0] + x[1] I am trying to convert these equations to lambda functions using eval() in python and then use them in an optimization scheme. Here is what I do: def gen_const(input): list = input.read_eqs() for i in list: m = lambda x: eval(i) cons.extend([{'type': 'ineq', 'fun': m}]) return cons This cons fails when it is used inside the optimization scheme. However, if I only consider the first round inside the loop

问题 I have encountered a snippet of code where call contains another call. For example: a <- 1 b <- 2 # First call foo <- quote(a + a) # Second call (call contains another call) bar <- quote(foo ^ b) We can evaluate calls with eval ( eval(foo) ), however eval(bar) won't work. This is expected as R tries to run "foo" ^ 2 (sees foo as non-numeric object). How to evaluate such callception ? 回答1: To answer this question it might be helpful to split it up in 3 sub problems Locate any call within a
