去掉url的所有参数

window.location.href=window.location.href.split('?')[0]

去掉指定的参数

function funcUrlDel(name){
    var loca = window.location;
    var baseUrl = loca.origin + loca.pathname + "?";
    var query = loca.href.split('?')[1]
    if (query.indexOf(name)>-1) {
        var obj = {}
        var arr = query.split("&");
        for (var i = 0; i < arr.length; i++) {
            arr[i] = arr[i].split("=");
            obj[arr[i][0]] = arr[i][1];
        };
        delete obj[name];
        var url = baseUrl + JSON.stringify(obj).replace(/[\"\{\}]/g,"").replace(/\:/g,"=").replace(/\,/g,"&");
        console.log(url,'urlurlurlurl')
        return url
    };
}
