Wang of numbers to uppercase

Usage scenario: You usually need to fill in uppercase numbers when writing regular amounts.

Implementation function: Digital to capitalize the main implementation: input lowercase Arabic numerals, converted to uppercase

Data example: input, 12345678.90 output, RMB: RMB ba Yuan, Qian Bai

Feature implementation:

HTML code

<Divclass= "Input-group">    <inputname= "KW"type= "text"class= "Form-control"placeholder= "Number"ID= "Lower"value= "12345678.90">    <Divclass= "Input-group-btn">    <Buttontype= "Submit"class= "Btn btn-success"ID= "Convert">Transformation</Button>        </Div></Div>

JS Code

<script src= "/wxp123/public/js/number/numberconvert.js" ></script> <script type= "Text/javascript" >                  $(function(){                      $("#convert"). Click (function() {Lower= $ ("#lower"). Val (); Upper=convertcurrency (lower); $("#upper"). val (upper);                      }); $("#lower"). Change (function() {Lower= $ ("#lower"). Val (); Upper=convertcurrency (lower); $("#upper"). val (upper);                  });               }); </script>
