the method of realizing trapezoidal multiplication table by JavaScript

This article mainly introduces the JavaScript realization trapezoidal multiplication table method, involves the basic JavaScript combination table operation skill, needs the friend to be possible to refer to under

In this paper, we illustrate the method of JavaScript realization of trapezoidal multiplication table. Share to everyone for your reference. Specifically as follows:

The effect is shown in the following illustration:

The table is table,tr,td in HTML and then implemented with a for statement, loops out rows and columns, multiplies by the number of ranks, the first for loop outputs 9 rows, and then inserts a for, takes the value of the first for loop in the conditional expression and then outputs the table operation, Why take the first for loop, because the number of first for loops is the trapezoid arrangement rule, the trapezoid arranges the rule is the first row one lattice, the second row two squares, the third row three squares, and so on.

The complete code is as follows:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23-24
