function urlParse() {
  let url = window.location.search;

删除url指定参数

function deleteParams(name){
    var loca = window.location;
    var baseUrl = loca.origin + loca.pathname + "?";
    var query = loca.search.substr(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,"&");
        return url
    };
}

删除url指定参数（vue hash模式 有#删除指定参数问题）

function deleteParams(name) {
   var loca = window.location;
   var baseUrl = loca.origin + loca.pathname + loca.hash.substring(0, loca.hash.indexOf('?') + 1);
   var query = loca.hash.substring(loca.hash.indexOf('?') + 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, "&");
         return url
    }
},
