copy

问题 That's it :) I have a div with the id #toCopy , and a button with the id #copy . What's the best way to copy #toCopy content to clipboard when pressing #copy ? 回答1: UPDATED ANSWER Javascript was restricted from using the clipboard, early on. but nowadays it supports copy/paste commands. See documentation of mozilla and caniuse.com. document.execCommand('paste') make sure that you support browsers that don't. https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand http://caniuse

问题 I have a specific problem. I have to transform an XML structure to other, where the base XSD is same, different only the namespace definition. The first part is simple, because here I have to use field-mapping. The second part is the simple copy. And here is the problem. The copied "main" node contains the original xmlns attribute.

问题 I wonder whether copying a vector I am copying the vector with its values (whereas this is not working with array, and deep copy need a loop or memcpy). Could you hint to an explanation? Regards 回答1: You are making a deep copy any time you copy a vector. But if your vector is a vector of pointers you are getting the copy of pointers, not the values are pointed to For example: std::vector<Foo> f; std::vector<Foo> cp = f; //deep copy. All Foo copied std::vector<Foo*> f; std::vector<Foo*> cp = f

问题 I am trying to write a multithreaded program in Python to accelerate the copying of (under 1000) .csv files. The multithreaded code runs even slower than the sequential approach.
