Javascript：在Enter Key按下提交阻止表单

问题描述：

我有一个网页，当我点击回车键时，我有两个表格，我正在调用一个javascript函数来强制页面加载另一个页面。我的代码是

I have a web page where i have 2 forms when i click the enter key, I am calling a javascript function to force the page to load another page.My code is

function SearchUser()
{
var text = document.getElementById("searchItem").value;
text = text == "" ? -1 : text;
var by = document.getElementById("listBy").value;   
var on="";
if(by==1)
{
    on="USERNAME";
}
else if(by==2)
{
    on="FIRSTNAME";
}
else if(by==3)
{
    on="EMAIL_ID";
}

gotoUrl="userlist.php?searchItem="+text+"&onSearch="+on; 
    alert(gotoUrl); 
window.navigate=gotoUrl;

}

和

$(document).ready(function()
{
 $("#frmUserListSearch").keyup(function(event)
 {
  if(event.keyCode == 13)
  { 
    SearchUser();
  }
 });

}）;

但页面正在填写表格在调用SearchUSer函数时提交。我在alert中获取了正确的url。但是页面没有加载到浏览器中

But the page is doing a form submit when the SearchUSer function being called.I am getting the correct url in the alert.But The page is not loading in the brower

任何想法???

答

if (document.addEventListener) {
    document.getElementById('strip').addEventListener('keypress',HandleKeyPress,false);
} else {
    document.getElementById('strip').onkeypress = HandleKeyPress;
}

function HandleKeyPress(e) {
    switch (e.keyCode) {
        case e.DOM_VK_ENTER:
        if (e.preventDefault)
            e.preventDefault();
    else e.returnValue = false;
    }
}

由于原始问题编辑而编辑：

EDIT due to original Question edit:

您只需要：

$(document).ready(function()
{
    $("#frmUserListSearch").keyup(function(event)
        {
            if(event.keyCode == 13)
            {     
                SearchUser();
                if (e.preventDefault)
                    e.preventDefault();
                else e.returnValue = false;
            }
        });
});
