This article describes how to format the amount, characters, and time in javascript. Examples of common javascript conversion techniques such as amount, character, and date are analyzed, which has some reference value, for more information about how to format the amount, characters, and time in JavaScript, see the examples in this article. Share it with you for your reference. The specific implementation method is as follows:

The code is as follows:

// Convert the amount to uppercase
Function toDaX (num ){
// Case-sensitive conversion of the amount
If (isNaN (num) | num> Math. pow (10, 12 ))
Return "";
Var cn = "";
Var unit = new Array ("qibai", "points ");
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 (/^ pick up/, "pick up ");
Tmp = (tmp1 + unit1 [I]. charAt (j-1) + tmp;
}

}
