获取地址栏中参数

function getUrlParam(name) {
            let reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)');
            const urlStr = window.location.href;
            const state = urlStr.includes('?');
            if (state) {
              let str = urlStr.split('?')[1];
              let r = str.match(reg);
              if (r != null) return decodeURI(r[2]);
            }
            return '';
        }
        console.log(this.getUrlParam('tab'))
        console.log(this.getUrlParam('code'))
        console.log(this.getUrlParam('status'))

修改指定的地址栏参数

 function changeURLArg(url,arg,arg_val){ 
    var pattern=arg+'=([^&]*)'; 
    var replaceText=arg+'='+arg_val; 
    if(url.match(pattern)){ 
        var tmp='/('+ arg+'=)([^&]*)/gi'; 
        tmp=url.replace(eval(tmp),replaceText); 
        return tmp; 
    } else {
        if(url.match('[\?]')){ 
            return url+'&'+replaceText; 
        } else {
            return url+'?'+replaceText; 
        }
    }
    return url+'\n'+arg+'\n'+arg_val; 
}
console.log(changeURLArg('https://juejin.cn/search?query=js%20%E6%94%B9%E5%8F%98%E5%9C%B0%E5%9D%80%E6%A0%8F%E5%9C%B0%E5%9D%80&type=0','type', '9'))
