This article mainly introduces the operation techniques of the jquery array, and the friends who need it can refer to the following 1. $.each (array, [callback]) traversal [Common]nbsp; nbsp; Interpretation: Unlike the $.each () method of the JQuery object, this method can be used to iterate over any object (not just the array). The callback function has two parameters: the first is the index of the member or array of the object, and the second is the corresponding variable or content. If you

1. $.each (array, [callback]) traversal [common] Explanation: Unlike the $ (). each () method of the JQuery object, this method can be used to sample any object. The callback function has two parameters: the first is the index of the member or array of the object, and the second is the corresponding variable or content. If you need to exit each loop so that the callback function returns false, the other return values are ignored. Each traversal, believed to be new, is a variant of the For loop
