分享一下url字符串拼接

【?】开头     
【&】开头[参数隔断符号] 
【=】参数值

+'参数名'+参数值

`参数名${动态参数值}``

let url = '/pages/particulars/'
let id = 2;
let childColumn = 11;
let childColumnName = 33

let A = url+'?id='+ id +'&childColumn='+childColumn +'&childColumnName='+childColumnName;
console.log('A :>> ', A);
let B = `${url}?id=${id}&childColumn=${childColumn}&childColumnName=${childColumnName}`;
console.log('B :>> ', B);
