The regular expression verifies that the number format is not negative and the two digits are retained after the decimal point. The regular expression is as follows: ^ ([1-9] +) | ([0-9] + \. [0-9] {1, 2}) $ Tested. Very accurate. Attached JS judgment method: Function checkmoneyformat (VAL ){VaR Reg =/^ ([1-9] +) | ([0-9] + \. [0-9] {1, 2}) $ /;VaR ismoneyformatright = reg. Test (VAL );Return ismoneyfo

When processing the data of the currency type, we often encounter the display of the data of the currency type. For example, on a Chinese machine, the display format is always ￥50,200.00, If we want to display a format like $50,200, two points are involved:1. Set the current region to the United States. 2. Set the number of decimal places for the amount to 0. We can create a base class basepage an
