The example in this article describes the js method of formatting amounts, characters, and time. Share it with everyone for your reference. The specific implementation method is as follows:

Copy code The code is as follows:

//Convert the amount to uppercase
Function toDaX(num){
//Amount case conversion
If (isNaN(num) || num > Math.pow(10, 12))
                     return "";
           var cn = "zero one two three four five Lu seven eight nine";
            var unit = new Array("十百千", "分角");
var unit1 = new Array("Trillion", "");
If(parseFloat(num)==0||num==''){
Return "zero circle";
           }
var numArray = num.toString().split(".");
var start = new Array(numArray[0].length - 1, 2);
             function toChinese(num, index) {
var num = num.replace(/d/g, function($1) {
Return cn.charAt($1) unit[index].charAt(start-- % 4 ? start % 4 : -1);
                    });
                   return num;
           }
for ( var i = 0; i < numArray.length; i ) {
var tmp = "";
for ( var j = 0; j * 4 < numArray[i].length; j ) {
var strIndex = numArray[i].length - (j 1) * 4;
var str = numArray[i].substring(strIndex, strIndex 4);
var start = i ? 2: str.length - 1;
var tmp1 = toChinese(str, i);
                    tmp1 = tmp1.replace(/(zero.) /g, "zero").replace(/zero $/, "");
                                                                                                                                                        tmp1 = tmp1.replace(/^一十/, "十");
                      tmp = (tmp1 unit1[i].charAt(j - 1)) tmp;
                }
                 numArray[i] = tmp;
           }
numArray[1] = numArray[1] ? numArray[1] : "";
numArray[0] = numArray[0] ? numArray[0] "元" : numArray[0],numArray[1] = numArray[1].replace(/^zero/, "");
numArray[1] = numArray[1].match(/分/) ? numArray[1] : numArray[1] "whole";

/**Amount formatting Add "," separator*/

function addPercent(str){
    var percent = Math.floor(str * 100) / 100;

I hope this article will be helpful to everyone’s JavaScript programming design.
