通过javascript从URL中删除未使用的char

Question

我正在尝试从网址中删除自定义参数，但我做错了

有我的javascript

var removeFilterHelper = function(param) {
            var loc = location.protocol + '//' + location.host + '/Project/Search' + location.search;
            location.href = loc
                .replace(param, '');
}

例如，如果我喜欢这个网址：

http://localhost:5000/Project/Search/?categoryId=50,categoryId=20&subCategoryId=10

removeFilterHelper（ “的categoryId = 50”）;

结果如下：

http://localhost:5000/Project/Search/?,categoryId=20&subCategoryId=10

Answer 1

只需在您的参数中添加逗号即可。

＆＃13;

＆＃13;

var loc = "http://localhost:5000/Project/Search/?categoryId=50,categoryId=20&subCategoryId=10";
var param ="categoryId=50" + ','; // Also remove the trailing comma
console.log(loc.replace(param, ''))

＆＃13;
