【uniapp 开发】字符串工具类 StringUtil

替换字符串中的所有 “***” 子串

var str='Is this all there is';

var subStr=new RegExp('is','ig');//创建正则表达式对象,不区分大小写,全局查找
var result=str.replace(subStr,"");//把'is'替换为空字符串
console.log(result); //th all there 

var subStr=new RegExp('is','i');//创建正则表达式对象,区分大小写
var result=str.replace(subStr,"");//把'is'替换为空字符串
console.log(result); //this all there is

分割字符串为数组

var address= '111;222;333;444'
let addr = address.split(';');

隐藏店铺名称部分文字,至多隐藏四个字,

//例如：“ 欧莱雅旗舰店” 变为  **雅**店

    formatShopName: function(name) {
        var str_array = name.split("");
        
        if(str_array.length < 3){
            
        }
        else if(str_array.length == 3){
            name = name.replace(str_array[1],"*");
        }
        else if(str_array.length > 3){
            var index = 0;
            for (var i = 1; i < str_array.length; i+=2) {
                if(i!=str_array.length-1 && i!=str_array.length-2 && index<4){
                    name = name.replace(str_array[i],"*");
                    index ++;
                    console.log('name=='+name);
                }
            }
        }
        
        return name;
    },
