When deleting an element in the loop array, do not use the splice method.The problem occurs because splice causes the original array to change, and the array is still in the loop.Example:There are a number of groups FormData , requirements: Delete FormData itemlist, Queid = = = ' 001 ' of an item.The first thing I used was the splice method, but the error was: fo
Slice () and splice () are the Two methods of the prototype Array object in JavaScript, and because of the similarity of the method names, it is common to remember the roles of the two and make a clear distinction below. 1.slice (start[, end]) :Takes an element from an array, returns the sub-array that is fetched, and has no effect on the original array . Wherethe start parameter is required to indicate the starting position of the element, the end
First add a splice function:
Splice: The purpose of this method is to remove an element from an array
Array.splice (Index,count,value ...);
Index: Indicates from which subscript to start,
Count: Indicates the number of deleted elements
Value: Represents the added element
Example
1.var array = new Array (1,2,3,4,5,6);
Array.splice (0,1,2)
result:2,2,3,4,5
2.var array = new Array (1,2,3,4,5,6);

There are 10 small pictures with numbers ranging from 0 to 9 on hand. Now we need to splice them into a multi-digit integer image. In. net, bitmap and graphics can be used to achieve this.
First, we need to create a new bitmap as the result after splicing, and then create a graphics class instance for painting:

The splice () method of the JavaScript array changes the contents of the array, adds new elements, and eliminates the old elements.Grammar
Array.splice (index, Howmany, [element1][, ..., elementn]);
The following are the details of the parameters:
Index: The array at which the index starts to change.
