用javascript修改表单动作

我有用c＃/ asp.net编写的多步骤webform。我正在尝试更改发布到网址分析原因的网址。我已经编写了下面的代码来更改客户端的url，但似乎并没有在最后使用参数发布到url。几乎喜欢它在客户端的onsubmit被改回。有任何想法吗？用javascript修改表单动作

它看起来像你在身体而不是形式上设置动作。除非我错过了某些东西，否则您应该可以像这样修复问题：

function setaction(step) { 
    var frm = document.getElementsByTagName("form")[0]; 

    frm.setAttribute("action", "webform1.aspx?step=" + step); 
    alert(document.location.href); 
}
