1.获取地址栏参数

方法一：

const url = 'https://sls.console.aliyun.com/next/project/test-hz-hbb/logsearch/amber-hsinga?spm=5176.2020520112.108.d7.794b34c0Ocwl5o&hiddenBack=true';

function getUrlParams(url, hiddenBack) {
    let oUrl = new URL(url);
    return oUrl.searchParams.get(hiddenBack);
}
getUrlParams(url,'hiddenBack');    // "true"

方法二：

const url = 'https://sls.console.aliyun.com/next/project/test-hz-hbb/logsearch/amber-hsinga?spm=5176.2020520112.108.d7.794b34c0Ocwl5o&hiddenBack=true';

function getURLParams(url){ 
    let q={} 
    url.replace(/([^?&=]+)=([^&]+)/g,(_,k,v)=>q[k]=v) 
    return q 
}
getURLParams(url)
 //{spm: "5176.2020520112.108.d7.794b34c0Ocwl5o", hiddenBack: "true"}
