lastZero:function (num) {
var reg = /0+$/;
return reg.test(num)
}I wrote a rule, but I still think that the rule is just to determine whether the last number is 0
. what I want is some data returned in the background. If the end of these numbers is 0, I will make the colors of these 000s different, like
excuse me, how should this effect be achieved, whether it is in vue, is it possible to do it with a filter or other js code?
can you provide a sample code?
vue has not been used, but you can probably use 000 to deal with
.function splitNum(numStr){
var regex=/^(?=.*\.)([\d.]*?)(0+)$/;
var result=numStr.match(regex);
return result?(result[1]+","+result[2]):numStr;
}function lastZero(numStr){
var regex=/[^0](?=0+$)/;
return numStr.indexOf(".")>=0?numStr.replace(regex,"$&,"):numStr;
}regular can take out two parts of data at the same time
let str = "123.320000" ;
Number(str) //
// 123.32
str.length - String(Number(str)).length 0
//4
forgive me for forgetting the regular pattern.
