First of all, the method of JS acquisition, which is more troublesome than the jquery method, followed by the jquery method for comparisonJS is a lot more troublesome than jquery, mainly because the FF browser, the FF browser, will take your newline as the most DOM element.Native JS Gets the child element under the element with ID test. Can be used:Like what:var a = Docuemnt.getelementbyid ("Dom"). Geteleme

Zeng Teacher's "Basic course of finite element Analysis" The third chapter has the derivation of two-dimensional rod element, and combines an example to analyze and solve the program based on MATLAB. But I feel the MATLAB code in the book is a bit wordy, and some of the implementation methods are more troublesome, such as already know the starting point and the end point coordinates, still need to give the

I have to say, Mathematica is a really good thing, before learning finite element, for the equation deduction in the book, see the past, never thought to deduce it yourself again, because the manual derivation is too complex. With the MM, the original very complex things suddenly become simple. 1. Unit Geometry Description is pure curved beam unit, length L, modulus e, area A, moment of inertia I. The displacement arrays of two nodes 1 and 2 are \[Q^

Finds all the parent elements of the current element until the matching element is encounteredIf the provided jquery represents a set of DOM elements, the. Parentsuntil () method also allows us to search through the ancestor elements of all elements until we encounter an element that matches the supplied parameter.
