JS 封装queryURLParameter方法

// 实现一个方法queryURLParameter获取一个URL地址问号？后面的参数信息
let url = 'http://www.baidu.com?id=123&name=hello&sex=1#box'
/*
    期望结果：{
        id:123,
        name:'hello',
        sex: 1
    }
*/
// 1.获取问号后面的值
let askIndex = url.indexOf('?')
let wellIndex = url.indexOf('#')
let askText = url.substring(askIndex + 1,wellIndex)
let wellText = url.substring(wellIndex + 1)
console.log(askText) // =>id=123&name=hello&sex=1
console.log(wellText) // =>box
// 2.问号后面值的详细处理
let askAry = askText.split('&')
console.log(askAry) // => ["id=123", "name=hello", "sex=1"]
let result = {}
askAry.forEach(item =>{
let keyValue = item.split('=')
result[keyValue[0]] = keyValue[1]
})
result["hash"] = wellText
console.log(result) // =>{id: "123", name: "hello", sex: "1", hash: "box"}
/*
   queryURLParams: 获取URL地址中问号传参的信息和哈希值
   @params: url[string] 要解析的URL字符串
   @return [object]包含参数和哈希值的对象 
*/
function queryURLParams(url){

    let askText = ''
    //url.substring(askIndex + 1,wellIndex)
    let wellText = ''
    //url.substring(wellIndex + 1)
    // #不存在
    wellIndex === -1 ? wellIndex = url.length : null
    //?存在
