js跳转action带参数

// 假设你要跳转到'action.html'并且带上参数'id=123'
window.location.href = 'action.html?id=123';

// 获取URL中的查询参数
function getQueryParam(param) {
    var urlParams = new URLSearchParams(window.location.search);
    return urlParams.get(param);
}

var id = getQueryParam('id'); // '123'

<form action="action.html" method="get">
    <input type="hidden" name="id" value="123">
    <button type="submit">Submit</button>
</form>

function submitFormWithParams(action, params) {
    var form = document.createElement('form');
    form.method = 'POST'; // 或者 'GET'
    form.action = action;

    for (var key in params) {
        if (params.hasOwnProperty(key)) {
            var input = document.createElement('input');
            input.type = 'hidden';
            input.name = key;
            input.value = params[key];
            form.appendChild(input);
        }
    }

    document.body.appendChild(form);
    form.submit();
}

// 使用示例
submitFormWithParams('action.html', { id: '123' });
